SET RUNTIMESUBVARS - my favorite new feature in 11.1.2.3

Hi there,
I must say it!
My favorite new feature in 11.1.2.3: SET RUNTIMESUBVARS see here:
http://docs.oracle.com/cd/E40248_01/epm.1112/essbase_tech_ref/frameset.htm?set_runtimesubvars.html
No longer the need in a MaxL scipt to create and/or set server variables first to be used in calculation (csc) and no need to delete or reset or to tidy up them.
(And no more (these senseless) error messages in MaxL protokoll saying that a variable already exists)
It is much leaner and cleaner now.
Thats pretty cool! You should take a look...
Thank to the dev team and best Regards
Andre

I have often found that the pleasure related to the anticipation of an event or thing is often greater than the actual act or thing. We anticipate that it is gonna work. However here is the reality (or I think it is)
FIX(Jan,Sales,"100-10",@RELATIVE(Market,0))
     "Actual"(
        IF(@ISUDA(Market,"Major Market"))
                    @CREATEBLOCK (@UDA(Market,"Major Market"));
        100;
        ENDIF
ENDFIXI don't see it working. Techref says use @CREATEBLOCK under a FIX (If you use it without opening a block you get this error "Error: 1012000 Invalid Syntax - Not a CALC command [@CREATEBLOCK]")
SET RUNTIMESUBVARS works if you can assign a value to the variable.
SET RUNTIMESUBVARS
   myMarket ="New York";
   salesNum = 120;
   pointD ="Actual"->"Sales";
FIX(Jan,&myMarket)
     Actual(
          &pointD=&salesNum;
ENDFIXHowever if you use the prompt string (I'm not sure where the prompt will appear (Tech Ref says it is calc script, so I'm assuming that when we validate it should prompt for input)
SET RUNTIMESUBVARS
   myMarket <RTSV_HINT>myMarket: Input the value as a string, such as "New York"</RTSV_HINT>;
   salesNum <RTSV_HINT>salesNum: Input the value as an integer, such as 100</RTSV_HINT>;
   pointD <RTSV_HINT>pointD: Input the value as a member name or a member combination, such as "Actual"->"Sales"</RTSV_HINT>;
FIX(Jan,&myMarket)
     Actual(
          &pointD=&salesNum;
ENDFIXI think we've to wait for more inputs on these.

  • What are your top three favorite new features in 8?

    First off, let me say that I am blown away with this update. It really has almost everything I could have hoped for. Bug fixes, workflow improvements galore, not a bunch of new plug ins but great improvements on the old ones, and I personally love the new look. Job well done apple. Three features that will revolutionize the way I work:
    1. Key command for hiding plug ins. Some plugs take a ton of time for the graphics to load, that used to be really annoying.
    2. Key command for disabling control surfaces. I am always needing to switch from using my control surface as a mixer controller to using it to quickly automate some CC on a MIDI track. This makes it very quick and easy.
    3. Delay Designer. I just got into this one, absolutely amazing. Those melodic patterns really got me excited. This completely obliterates any other delay I've ever seen feature wise, and the interface is great. I used to use Ohmboyz as my go to for complex delays, but Delay Designer blows it away from what I can tell. The compressor improvements are very nice as well!

    1. Mainstage - Even though I probably won't use Logic for live performance much, I love how simple, clean, and intuitive the interface looks. I will probably use this when composing as it seems to be one of the easiest ways to route drum pads, create keyboard layers, etc. really quickly, and the interface is very inviting.
    2. Delay designer looks really fun. I remember spending 30 minutes once in Sonar trying to get the stupid delay to do a really simple thing. I finally gave up and layered the audio data to make my own delay because it didn't give me enough control to make it happen in the plugin. It looks like I could have just drawn it into the Delay Designer and been done with it.
    3. Import from Garageband - Not a new feature, but I love using Garageband as a musical notepad when all I want to do is create something simple or jot down an idea. In this period, I don't need all the features of Logic, but I will eventually, and then I just open it up in Logic and get more advanced.

  • Favorite new Pages and iWork '09 features?

    What do you think, guys?
    I will get us started. My favorite new feature is the interface with EndNote, although I have noticed one bug that has to do with formatting Book citations (it won't make the titles italic). I think Pages' iteration of CWYW is much more user-friendly and much more intuitive and workflow friendly than Word's. There is no acknowledgment on Endnote's page that it works with Pages. Did Apple go at this alone? Or did they work with Thomson Research?
    The full-screen and outlining features seem to work as advertised and are long overdue. I wish that Apple would have allowed you to changed the background of the page in fullscreen rather than just the gutter.
    Has anyone noticed any unadvertised new features? So far, I've noticed that:
    1. You can now reduce file size from the File menu which hopefully means there will no longer be 18 MB Pages files using the original images instead of the edited ones,
    2. Word count is in the status bar (which is much more intuitive and works much better than word count in the inspector),
    3. There's a scroll widget that allows you to designate what you want to scroll through,
    4. Export... is gone,
    5. You can now insert Auto page numbers and filenames.
    Also, in Numbers, you can finally Freeze columns or rows, which should have been included in the 1.0 release.
    Anything else?
    Overall, I'm very happy with this update. Pages is now only missing a few things for me (split pane and multiple orientations within a document), and those few things are easily done without. I've been using it since Pages 1.0, and it seems that Pages 4.0 finally gets it (mostly) right. Although I said goodbye to Microsoft Word a few years back, with 4.0 I don't even miss it anymore (actually that happened with 3.0). This version of Pages reminds me of Keynote 3.0, when PowerPoint became a distant memory.
    --S.

    Henrik, if you had answered simply "yes" or "no", everyone would have understood within a fraction of a second.
    Det er ret og rimeligt / that's right and reasonable.
    In so far as Apple does not provide access to drawing glyph designs with Private Use Area 'characters' supplied by the Adobe Type Library and the Linotype Type Library in so-called OpenType, then the public source character string stays intact in Pages, as it should.
    (Unhappy the Word users who have Adobe and Linotype products since the intention of Adobe and Linotype is to 'help' them bastardize their public character strings.)
    Meanwhile, in PDF the source characters for anything in the font file that is not directly drawn as a character code - ligature reshaping which is automatic, reshaping which is specified selectively by the user e.g. small capitals - is unsafe for searching.
    Obviously, Al Gore interchanges PDF. There are probably not that many people Al Gore might be working with who interchange the source Pages file format. Especially since there seem to be many, many, many users who have had trouble with that.
    Perhaps, while on the subject of denial, the problem of PDF, the problem of PDF from PostScript, the problem of Type 1, the problem of 'OpenType' and the general problem of the place of the configurable name space model introduced in PostScript in 1985 is deserving of discussion. Because if you begin by corrupting or clipping your character string, you are left guessing.
    At this point, the person who has the contract to develop the PDF/X validation and the PDF/A validation for Adobe is Olaf Drümmer of Callas in Berlin. And the person who provides the patented heuristics for synthesising character strings from glyph identifiers is Thomas Merz of PDFLib in München. This is the technology sold in Adobe Acrobat Professional. The project is applying pressure where pressure should be applied offline and online. And if you want to apply pressure, now you know where.
    Best,
    Henrik

  • What are your favorite apps/new features you like after the 2.0 upgrade?

    I discovered one feature by mistake, after finally getting my iPhone going again! I pressed the top button and home button at the same time once and saw a white flash on the screen! It turns out it works like a print screen button!! Very cool! Whatever you see on your iPhone, you can save directly to your photos, just press those two buttons simultaneously once until it flashes! If you guys already knew about this, I apologize. Please post any other favorite new features or apps here!! Thanks.

    Well the update worked fine for me and one thing I love is that I can access the app store using the Edge network & not just via wi-fi. but if i can access the app store over the edge network then why not allow users to access the itunes store over the edge network as well? either way i'm happy. also, i liked the fact that when i tested the "locate me" feature in maps that the iphone prompted me for permission. that's a great security feature so that other ppl can't try to access your phone remotely or something and try to determine your location w/o your permission.

  • History applies default presets of new features

    In LR3, I set as default the new feature "Enable Profile Corrections". That's fine for newly imported pictures, but if I play with the history of a picture which was imported with an older version (clicking on some step in the history), the feature will sometimes (pretty randomly, as it seems to me) be activated and when I go back to the history step where I was before the picture has changed (with e.g. double correction of vignetting). It means that in some cases you cannot revert to the developed picture you had originally selected, and that's really bad. A similar (though less acute) problem exists with camera calibration profile if you click on a history step named "reset settings": the actual default settings are applied and you cannot revert to the originally developed picture using history.
    The problem also exists with snapshots: a snapshot of a picture with "Enable Profile Corrections"=No can activate this feature when recalled. Not in all cases - I simply cannot find out what the logic is.
    Can somebody help and propose a workaround? I find it extremely annoying to know that the settings I selected for my pictures perhaps cannot be reverted to when playing with history.
    Pierre

    OK, here is an example:
    Here is the picture as I imported and developed it in an older LR version (it's a Nikon NEF with an xmp companion):
    Now I click in history on an older state (here "Quantité de vignettage", i.e. vignetting):
    Note that Profile Corrections are now checked (and vignetting is doubly corrected, once automatically and once manually.)
    If I get back to the initial state:
    Profile Correction is still enabled; the picture has changed although the history state is the same as originally.

    Hi I am currently have a subscription to PS CC but I don't think I have the latest version.  I believe this because I don't get the new welcome screen and don't have new features like the structure and color setting in the content aware patch tool.  I have checked for updates and it tells me I have the current version.  I check in PS I have version 14.2.1.  I also have CS6 installed on my PC, could this be somehow be doing something or am I doing something wrong.  Would anyone have any suggestions.

  • Camera RAW 8.3 new feature to set White and Black Sliders

    How does the new feature in ACR 8.3 and Lightroom 5.3 to shift double click the White and Black sliders affect the recommended way to adjust an image?

    I found this out by accident, but it is mentioned in the release notes for the PS-CC ACR 8.3 RC plug-in, not LR, but it works in both products.  The Temp and Tint also have independent auto-behavior, now, too:

    I am glad there was a copy paste added but it would have been nice to use your own ringtones and I don't understand why they could not use gps for the direction of the phone too.
    I am sure if they can pinpoint you on the map they could tell what direction your holding the phone on the 3g.
    The cam is very poor on the 3g phone it,s more like an afterthought.
    I don't understand why apple did not have the function of moving your photos and ringtones with drag and drop onto itunes rather than sync to a folder.
    yes there are apps you can buy but even a £20 phone lets you do all of above without added cost to the user.
    and where is the software reset for clearing the memory or is that an afterthought too.
    PS not picking holes it's a fact.
    The HTC phone is a nice phone mate has one.

  • FAQ: New feature overview

    This text guide helps you find most major new features in Photoshop CS. For a comprehensive video walkthrough, see this Ask A Pro session with Senior Product Manager Zorana Gee. 
    Retouching and transforming
    Content-Aware Move tool
    The Content-Aware Move tool lets you quickly recompose images without complex layering or slow, precise selections. Extend mode convincingly expands or contracts objects such as hair, trees, or buildings. Move mode lets you place objects in completely different locations (most effectively when the background remains similar).
    In the toolbar, hold down the Spot Healing Brush, and select the Content-Aware Move tool.
    In the options bar, choose Mode > Extend or Move. Adaptation options control how closely the new area reflects existing image patterns.
    In the image, circle the object you want to extend or move, and drag it to a new location.
    Tip: To best extend architectural objects, use photos shot on a parallel plane, rather than at an angle.
    Content-Aware Patch tool
    The updated Patch tool includes a Content-Aware option that seamlessly replaces unwanted image elements by synthesizing nearby content. The natural-looking results are similar to Content-Aware Fill, but the Patch tool lets you select the area from which the fill is drawn.
    In the toolbar, hold down the Spot Healing Brush, and select the Patch tool.
    In the options bar, choose Patch > Content-Aware. Adaptation options control how closely the patch reflects existing image patterns.
    In the image, circle the area you want to replace, and drag over the area you want to generate a fill from.
    Redesigned Crop tools
    The redesigned Crop tool provides an interactive preview so you can better visualize results. A streamlined set of toolbar options includes a helpful Straighten tool, and aspect ratio controls you can adjust while a crop is active in the image window. (To maintain the current aspect ratio or resolution, right-click the image to access additional options.)
    To crop an image, click the Crop tool in the toolbar. Then either adjust default crop borders in the image window, or drag in the window to start with specific borders.
    Note: If you deselect Delete Cropped Pixels to apply a nondestructive crop, you can later click the image to see areas outside current crop borders.
    To correct image perspective, hold down the Crop tool and select the Perspective Crop tool.
    Type
    Paragraph and Character styles
    In the Window > Paragraph Styles panel, create, store, and reapply the characteristics of groups of highlighted sentences. In the Window > Character Styles panel, specify the look of selected letters, words, or phrases.
    Double-click existing styles to edit them and update all associated text in the current document. From the panel menus, save and load styles to apply them to other documents. Or drag styles from one document to another.
    Type styles are hierarchical: Manual overrides replace any applied character styles, which in turn replace applied paragraph styles. This hiearchical approach lets you combine the efficiency of styles with the flexibility to customize your designs.
    Tip: To create a style without first selecting text, click the Create New Style icon [ICON] at the bottom of the Paragraph or Character Styles panel. To edit a style without applying it to text, select an image layer, such as the Background.
    Drawing
    Vector layers
    The Line and Shape tools now create fully vector-based objects. Apply strokes and fills using the options bar. Stroke objects with dashed lines and other designs. Fill objects with preset or user-defined gradients, colors, and patterns.
    To later revise stroke and fill settings, simply select the object layer, and then select the Path Selection or Direct Selection tool.
    Tip: To reduce anti-aliased edges, ensuring that vector objects look as sharp as possible, select Align Edges in the options bar.
    Intuitive path editing
    By default, dragging with the Direct Selection tool adjusts multiple related segments, letting you quickly transform path shapes. To edit only segments between selected anchor points, reflecting previous Photoshop versions, select Constrain Path Dragging in the options bar.
    Video
    Choose Window > Timeline to access the redesigned, clip-based Timeline panel, including transitions and effects that give finished videos professional polish. Easily change clip duration and speed, and apply motion effects to text, still images, and Smart Objects.
    Video Groups combine multiple video clips and content such as text, images, and shapes on a single Timeline track. Separate audio tracks allow for easy editing and adjusting.
    The redesigned video engine also supports a wider range of import formats. When you're ready to output final video, choose File > Export > Render To Video. Photoshop provides helpful presets and options for the DPX, H.264, and QuickTime formats.
    Note: In Windows, you must install QuickTime separately.
    Correcting wide-angle lenses
    Choose Filter > Adaptive Wide Angle to quickly straighten lines that appear curved in panoramas or photos shot with fisheye and wide-angle lenses. The filter uses the physical characteristics of individual lenses to automatically correct images.
    Fine-tune the adjustments with these options in the Adaptive Wide Angle dialog box:
    In the upper left of the dialog box, choose the Constraint or Polygon Constraint tool. Then drag across key objects you want to straighten or align vertically or horizontally. (If necessary, right-click constraint lines in the image, and choose an orientation from the pop-up menu.)
    In the upper right of the dialog box, choose the lens type and focal length, and adjust Scale andCrop Factor to compensate for any blank image areas the filter introduces. (To save and load customized settings for use with future images, click the menu icon.)
    Tip: To see a visual representation of the transformations applied to the image, select Show Mesh at the bottom of the dialog box.
    Photographic blur gallery
    Choose Filter > Field Blur, Iris Blur, or Tilt-Shift to quickly create three distinct photographic blur effects with intuitive on-image controls.
    Use Iris Blur to add one or more focus points to your photo. Then move the on-image controls to alter the size and shape of the focus points, the amount of blur in the rest of the image, and the transition between sharp and blurred areas.
    For a different look, build a gradient blur effect using the Field Blur option, placing multiple pins with different blur amounts. Or align blur along one or more planes with the Tilt-Shift option.
    With the blur adjustments complete, style the overall effect with Bokeh brightness and color controls.
    Tip: Combine multiple blur types to produce creative results.
    Camera Raw 7
    Simplified Basic controls in the Develop tab improve highlight and shadow rendering. New local corrections are available for white balance, highlights, shadows, noise reduction, and moiré.
    The new Basic sliders and new local adjustments options appear when you process new images or convert previously-processed images to Process Version 2012 (PV2012). To convert an image, click the exclamation-point icon in the lower-right corner of the image preview area.
    Selecting and adjusting colors
    Skin-tone selection and face-detection
    Choose Select > Color Range. Then, from the top pop-up menu in the Color Range dialog box, choose Skin Tones to easily isolate those tones. To reduce the resulting selection to faces in the image, select Detect Faces.
    Or, start off by selecting only faces: Choose Sampled Colors from the top pop-up menu, and then select Localized Color Clusters and Detect Faces. This approach lets you use the eyedropper samplers to refine the selection.
    Note: To create a selection that preserves skin tones while you adjust the color of everything else, select Invert below the eyedropper samplers.
    Improved Auto corrections
    Perfectly enhance your images in a single step with improved Auto options for theLevels, Curves, and Brightness/Contrast adjustments.
    Painting and patterns
    Oil Paint filter
    Choose Filter > Oil Paint to easily create the look of a classic painting.
    Erodible and airbrush tips
    Choose Window > Brush Presets to quickly access new erodible and airbrush tips, or Window > Brush to customize them.
    Erodible pencils and pastels wear down naturally with use. Customize a variety of Brush Tip Shape options: Softness controls the rate of wear, Shape provides settings from flat to round, and Sharpen Tip returns to original crispness. As you paint, watch the amount of wear with the Live Brush Tip Preview to the upper left of the image.
    Airbrush tips replicate spray cans with a 3D conical spray. Customize Brush Tip Shape options like Granularity,Spatter, Hardness, and Distortion controls. With a stylus, alter the spread of sprayed strokes by changing pen pressure.
    Brush Pose holds stylus tilt, rotation, and pressure
    Choose Window > Brush, and select Brush Pose to paint with a specified tilt, rotation, and pressure. Use a stylus to change the stroke relative to the default pose, or select Overrideoptions to maintain a static pose.
    Brush Projection applies stylus tilt and rotation to tip shapes
    Choose Window > Brush, and select Shape Dynamicsfrom the list at left. At the bottom of the options at right, select Brush Projection. As you paint with a stylus, changes to tilt and rotation alter the tip shape.
    Color Dynamics remain consistent for each stroke by default
    Color Dynamics settings automatically vary color as you paint. In previous versions of Photoshop, dynamics settings changed color for each distinct tip stamp in a stroke. In Photoshop CS6, however, dynamic changes occur once at the beginning of each stroke. This lets you vary color between strokes, rather than within each individual stroke.
    To revert to the behavior of previous versions, choose Window > Brush, and select Color Dynamics from the list at left. At the top of the options at right, select Apply Per Tip.
    Scripted patterns
    Select Edit > Fill, choose Pattern from the Use menu, and then select Scripted Patterns to choose from several geometric options. Build sophisticated designs by combining these scripts with Custom Pattern presets and blending modes.
    Workflow and workspace
    Fresh new look
    Work with a fresh, elegant interface with design enhancements like the following:
    Select from four different brightness levels: Choose Edit > Preferences (Windows) or Photoshop> Preferences (Mac OS). In the Interface section, select a Color Theme swatch.
    Note: To quickly decrease interface brightness, press Shift + F1. To increase brightness, press Shift + F2.
    On-image displays keep you informed as you use your favorite tools, showing dimensions for selections, angles for transformations, and more. To adjust the placement of these values, in the Interface preferences, choose an option from the Show Transformation Values menu.
    A new Mini Bridge gallery offers easier access to images and documents. Choose Window >Extensions > Mini Bridge.
    To maximize screen space, functions formerly in the application bar have moved elsewhere. To switch between Standard and Full Screen display modes, click the button at the bottom of the toolbar.
    Speed from Mercury Graphics Engine
    Experience blazing-fast interactions with processing intensive commands likeLiquify, Warp, Puppet Warp, and Crop.
    Layer filtering
    At the top of the Layers panel, new filtering options help you find key layers in complex documents quickly. Display subsets of layers based on name, kind, effect, mode, attribute, or color label.
    Preset migration and sharing
    Choose Edit > Presets > Migrate to easily move presets, workspaces, preferences, and settings from Photoshop CS3 and later to Photoshop CS6. Choose Edit > Presets > Export/Import Presets

  • ITunes 9.2.1 New Feature: Sync with iPhone 4 on-the-go?????

    The following was the first of a few new features in iTunes 9.2.1:
    "Sync with iPhone 4 to enjoy your favorite music, movies, TV shows, books and more on-the-go"
    Can someone who owns an iPhone 4 and has updated to iTunes 9.2.1 explain what this feature is?

    Hello, I have the same problem! (iTunes 9.0.1.8 iPhone 3G 3.1.2 (7D11) Windows7 64bit msi EX630 notebook)
    My temporally solution is bit anoying but simple!
    Everything is closed just iTunes is opened. System performance is set to max level.
    So transfer Your music just 1 album at once!
    So if You have 4albums to transfer just make it four times. If you transfer single tracks then make it just 8 or 10 songs at once.
    I don't know why it works but it works for Me...!
    ps: Apple need really fix this! It is annoying!

  • Oracle 10G New Feature........Part 1

    Dear all,
    from last couple of days i was very busy with my oracle 10g box,so i think this is right time to
    share some intresting feature on 10g and some internal stuff with all of you.
    Have a look :-
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Oracle 10g Memory and Storage Feature.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1.Automatic Memory Management.
    2.Online Segment Shrink
    3.Redolog Advisor, checkpointing
    4.Multiple Temporary tablespace.
    5.Automatic Workload Repository
    6.Active Session History
    7.Misc
    a)Rename Tablespace
    b)Bigfile tablespace
    c)flushing buffer cache
    8.ORACLE INTERNAL
    a)undocumented parameter (_log_blocks_during_backup)
    b)X$ view (x$messages view)
    c)Internal Structure of Controlfile
    1.Automatic memory management
    ================================
    This feature reduce the overhead of oracle DBA.previously mostly time we need to set diff oracle SGA parameter for
    better performance with the help of own experience,advice views and by monitoring the behaviour
    of oracle database.
    this was just time consuming activity.........
    Now this feature makes easy life for oracle DBA.
    Just set SGA_TARGET parameter and it automatically allocate memory to different SGA parameter.
    it focus on DB_CACHE_SIZE
    SHARED_POOL_SIZE
    LARGE_POOL
    JAVA_POOL
    and automatically set it as
    __db_cache_size
    __shared_pool_size
    __large_pool_size
    __java_pool_size
    check it in alert_log
    MMAN(memory manager) process is new in 10g and this is responsible for sga tuning task.
    it automatically increase and decrease the SGA parameters value as per the requirement.
    Benefit:- Maximum utlization of available SGA memory.
    2.Online Segment Shrink.
    ==========================
    hmmmmm again a new feature by oracle to reduce the downtime.Now oracle mainly focus on availablity
    thats why its always try to reduce the downtime by intrducing new feature.
    in previous version ,reducing High water mark of table was possible by
    Exp/imp
    or
    alter table move....cmd. but on these method tables was not available for normal use for long hrs if it has more data.
    but in 10g with just few command we can reduce the HWmark of table.
    this feature is available for ASSM tablespaces.
    1.alter table emp enable row movement.
    2.alter table emp shrink space.
    the second cmd have two phases
    first phase is to compact the segment and in this phase DML operations are allowed.
    second phase(shrink phase)oracle shrink the HWM of table, DML operation will be blocked at that time for short duration.
    So if want to shrink the HWM of table then we should use it with two diff command
    first compact the segment and then shrink it on non-peak hrs.
    alter table emp shrink space compact. (This cmd doesn't block the DML operation.)
    and alter table emp shrink space. (This cmd should be on non-peak hrs.)
    Benefit:- better full table scan.
    3.Redolog Advisor and checkpointing
    ================================================================
    now oracle will suggest the size of redo log file by V$INSTANCE_RECOVERY
    SELECT OPTIMAL_LOGFILE_SIZE
    FROM V$INSTANCE_RECOVERY
    this value is influence with the value of FAST_START_MTTR_TARGET .
    Checkpointing
    Automatic checkpointing will be enable after setting FAST_START_MTTR_TARGET to non-zero value.
    4.Multiple Temporary tablespace.
    ==================================
    Now we can manage multiple temp tablespace under one group.
    we can create a tablespace group implicitly when we include the TABLESPACE GROUP clause in the CREATE TEMPORARY TABLESPACE or ALTER TABLESPACE statement and the specified tablespace group does not currently exist.
    For example, if group1 is not exists,then the following statements create this groups with new tablespace
    CREATE TEMPORARY TABLESPACE temp1 TEMPFILE '/u02/oracle/data/temp01.dbf'
    SIZE 50M
    TABLESPACE GROUP group1;
    --Add Existing temp tablespace into group by
    alter tablespace temp2 tablespace group group1.
    --we can also assign the temp tablespace group on database level as default temp tablespace.
    ALTER DATABASE <db name> DEFAULT TEMPORARY TABLESPACE group1;
    benefit:- Better I/O
    One sql can use more then one temp tablespace
    5.AWR(Automatic Workload Repository):-
    ================================== AWR is built in Repository and Central point of Oracle 10g.Oracle self managing activities
    is fully dependent on AWR.by default after 1 hr, oracle capure all database uses information and store in AWR with the help of
    MMON process.we called it Memory monitor process.and all these information are kept upto 7 days(default) and after that it automatically purge.
    we can generate a AWR report by
    SQL> @?/rdbms/admin/awrrpt
    Just like statspack report but its a advance and diff version of statspack,it provide more information of Database as well as OS.
    it show report in Html and Text format.
    we can also take manually snapshot for AWR by
    BEGIN
    DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
    END;
    **The STATISTICS_LEVEL initialization parameter must be set to the TYPICAL or ALL to enable the Automatic Workload Repository.

    Benefit:- Now DBA have more free time to play games.....................:-)
    Advance version of statspack
    more DB and OS information with self managing capabilty
    New Automatic alert and database advisor with the help of AWR.
    6.Active Session History:-
    ==========================
    V$active_session_history is view that contain the recent session history.
    the memory for ASH is comes from SGA and it can't more then 5% of Shared pool.
    So we can get latest and active session report from v$active_session_history view and also get histortical data of
    of session from DBA_HIST_ACTIVE_SESS_HISTORY.
    v$active_session_history include some imp column like:-
    ~SQL identifier of SQL statement
    ~Object number, file number, and block number
    ~Wait event identifier and parameters
    ~Session identifier and session serial number
    ~Module and action name
    ~Client identifier of the session
    7.Misc:-
    ========
    Rename Tablespace:-
    =================
    in 10g,we can even rename a tablespace by
    alter tablespace <tb_name> rename to <tb_name_new>;
    This command will update the controlfile,data dictionary and datafile header,but dbf filename will be same.
    **we can't rename system and sysaux tablespace.
    Bigfile tablespace:-
    ====================
    Bigfile tablespace contain only one datafile.
    A bigfile tablespace with 8K blocks can contain a 32 terabyte datafile.
    Bigfile tablespaces are supported only for locally managed tablespaces with automatic segment-space management.
    we can take the advantage of bigfile tablespace when we are using ASM or other logical volume with RAID.
    without ASM or RAID ,it gives poor response.
    syntax:-
    CREATE BIGFILE TABLESPACE bigtbs
    Flushing Buffer Cache:-
    ======================
    This option is same as flushing the shared pool,but only available with 10g.
    but i don't know, whats the use of this command in prod database......
    anyway we can check and try it on test server for tuning n testing some query etc....
    SQL> alter system flush buffer_cache;
    System altered.
    ++++++++++++++++++
    8.Oracle Internal
    ++++++++++++++++++
    Here is some stuff that is not related with 10g but have some intresting things.
    a)undocumented parameter "_log_blocks_during_backup"
    ++++++++++++++++++++++++
    as we know that oracle has generate more redo logs during hotbackup mode because
    oracle has to maintain the a complete copy of block into redolog due to split block.
    we can also change this behaviour by setting this parameter to False.
    If Oracle block size equals the operating system block size.thus reducing the amount of redo generated
    during a hot backup.
    WITHOUT ORACLE SUPPORT DON'T SET IT ON PROD DATABASE.THIS DOCUMENT IS JUST FOR INFORMATIONAL PURPOSE.
    b)some X$ views (X$messages)
    ++++++++++++++++
    if you are intresting in oracle internal architecture then x$ view is right place for getting some intresting things.
    X$messages :-it show all the actions that a background process do.
    select * from x$messages;
    like:-
    lock memory at startup MMAN
    Memory Management MMAN
    Handle sga_target resize MMAN
    Reset advisory pool when advisory turned ON MMAN
    Complete deferred initialization of components MMAN
    lock memory timeout action MMAN
    tune undo retention MMNL
    MMNL Periodic MQL Selector MMNL
    ASH Sampler (KEWA) MMNL
    MMON SWRF Raw Metrics Capture MMNL
    reload failed KSPD callbacks MMON
    SGA memory tuning MMON
    background recovery area alert action MMON
    Flashback Marker MMON
    tablespace alert monitor MMON
    Open/close flashback thread RVWR
    RVWR IO's RVWR
    kfcl instance recovery SMON
    c)Internal Structure of Controlfile
    ++++++++++++++++++++++++++++++++++++
    The contents of the current controlfile can be dumped in text form.
    Dump Level Dump Contains
    1 only the file header
    2 just the file header, the database info record, and checkpoint progress records
    3 all record types, but just the earliest and latest records for circular reuse record types
    4 as above, but includes the 4 most recent records for circular reuse record types
    5+ as above, but the number of circular reuse records included doubles with each level
    the session must be connected AS SYSDBA
    alter session set events 'immediate trace name controlf level 5';
    This dump show lots of intresting information.
    it also show rman recordes if we used this controlfile in rman backup.
    Thanks

  • New Features and Improvements for CS6

    IMPORTANT:
    By default, Photoshop comes with the Proofing Colors (Cmd/Ctrl+Y) activated and set to CMYK. Adobe must warn about that, because I was editing a large amount of pictures for work and I was doing it under that color profile/work space.
    LAYERS PANEL:
    Layer Adjustments:
    Solid Color: visual feedback in real time.
    Gradient: IDEM as above.
    Pattern: IDEM as above.
    Gradient Map: IDEM as above.
    Gradient Editor: IDEM as above.
    Opacity and Fill: IDEM as above.
    Curves and Levels: Ability to load alfa channels. This way, the adjustments made on the alfa channel won't be destructive.
    CHANNELS PANEL:
    Channel Luminosity Selection:
    Ability to add and subtract from the selection.
    Ability to designate an area to be selected.
    For point 1, by using the shortcut Cmd+Alt+[number] the luminosity of a channel is loaded as selection. With Cmd+Alt+Shift+[number], the selection grows. But there is no way to subtract from selection (unless by clicking with the mouse on the channel's thumbnail). I think that can be solved by using Cmd+Alt+Shift+[- or +] in order to subtract or add from selection.
    Point 2 maybe even more important than point 1, because it allows selecting a designated area by the user, instead of the default luminosity selection, which ranges from 50% of the mid tones to the highlights (or shadows, if the selection is inverted). The user should be allowed to select the starting and finishing points of the luminosity selection.
    I thought 2 ways for solving these issues (and making it more intuitive and faster):
    A) By using the Histogram Panel, by dragging and highlighting an area on it, that it should load the selected luminosity pixels as a selection, as shown in figure 1:
      figure 1
    So the result of doing that will be a selection based on the area of the histogram that have been highlighted.
    B) By creating a new Adjustment Layer:
    It can be based in the same structure of the HUE Adjustment Layer, like figure 2 shows:
    Figure 2
    Or it can be this way (much better). Figure 3:
    Figure 3
    The selection can also be controlled by using the Click and Drag as suggested in the figure 1, as shown in the figure 4:
    Figure 4
    The overlaid highlighting over the histogram can be functional or just a mere graphic representation of the Range and Fade Selector. The "Fading" areas should be also be draggable in order to increase smooth the selection. However, the smoothing can be much better done with the Refining Selection tool and it can be ignored from this new tool.
    In any of these cases, the adjustments should give real time feedback when growing or shrinking selection; we must see the selection going bigger or smaller and also, the highlighted area should be draggable as well.
    TOOLS PANEL:
    Brush: detect edges while painting on masks (for manual mask refining. It would work similar to the Replace Color Brush, but only for masks and alfa channels). It also needs a shortcut to set the opacity.
    Dodge & Burn: Protect Tones should be allowed when painting on masks or alfa channels (for manual mask refining). D&B can also use edge detection as well.
    FILTERS:
    Some of them, like the ones involving Blur or the High-Pass and the Unsharp Mask filter, should work in real time (these ones, at the least).
    It can also added a Particle Generator Filter.
    It would be really nice having the ability to create particles such as dust, fog, rain, snow, etc in a more realistic manner than just the scattering function from the Brush Palette, or by mixing different filters with different blends. The Particle Generator should have an slider to control the depth of field, so it will give a feeling of depth and also, a way to load masks, so that way, the particles can exists before the image and also, behind. It would be great for creating a nice feeling of depth (kind of a bokeh effect).
    I've been playing with After Effect few times, and the way to create shapes and forms from nothing is the way of easier than in Photoshop.
    TIME LINE:
    I think it's time give dynamism the filters applied to a movie clip, and also, dynamics to the fade effects, like it happens in After Effects by adding Bezier Curves.
    HISTOGRAM:
    It should be possible to zoom in into the histogram, for a more precise feedback and analysis of the image tonal values.
    ADDITIONAL FEATURES:
    The fade tool should work in real time.
    Loupe/Magnificator View:
    This is very useful when it comes to edit and image in detail, with a lot of zoom, like 3200%. Unfortunately, Photoshop doesn't provide a real time feedback in an additional window, such as the Window/Arrange/New Window For […].
    It would be really useful having a window showing the image at fit on the screen while working on the other window at 100% or 3200% of zoom, but in real time. This way, you can see if you're doing a good job on the pixels or, if you're overdoing it.
    It happens that, when working with big images at 100% of the image size (or more), the brain cannot figure out how is looking the whole image, so having a realtime feedback in the other window would help a lot for detailled work.
    And why not, ading the same real time structure descrived above but to the Navigator, for faster and lighter use of the hardware capabilities. Probably, adding a check box to the navigator that blocks it to a given zoom, so when zooming into the image in the navigator, the image shown in the window isn't magnified too.
    Give me a chance to show you some examples of what I have done by improvising particles and fog about 5 years ago:
    http://mart1980.deviantart.com/gallery/5027033#/d1m119x
    And what I did 7 years ago by manually, selecting different shades of gray and using just Levels for 8 hours (which coule be done faster and easier with another tool I thought, which I will post later):
    I cannot post examples of the other features I'm suggesting because there are not such new features yet (I would have to create an hipothetical enviroment, but I think, you can fiure it out in your mind).
    Unfortunately, I don't know programing, even though, I tried something with Filter Factory, achieving good results, but that pluging consumes too much resources and/or is bad designed/have not the right tools for certain things.
    Hope this post is enough worthy of the Adobe's attention.
    Thanks,
    س

    This is a poorly explained reason about why is so important having a loupe in Photoshop. I've not also, used the best example, but I will. This belongs to the ADDITIONAL FEATURES: Loupe/Magnificator View:. Also, I will try to make my english clrearer, but here it goes:

  • (V7.3)RDBMS 7.3 Enterprise Edition NEW FEATURE에 대한 Q&A

    제품 : ORACLE SERVER
    작성날짜 : 2004-08-13

    2. Q) Oracle 7 Release 7.2와 7.3의 새로운 Parallel feature에는 어떤 것이
    있습니까?
    A) Oracle 7 parallel query 에 의한 parallel operation에는 다음과 같은 내
    용이 있습니다.
    > Parallel Data Loading : conventional and direct-path, to the same
    table or multiple tables concurrently.
    > Parallel Query : table scans, sorts, joins, aggregates, duplicate
    elimination, UNION and UNION ALL(7.3)
    > Parallel Subqueries : in INSERT, UPDATE, DELETE statements.
    > Parallel Execution : of application code(user-defined SQL functions)
    > Parallel Joins :
    nested loop,
    sort-merge,
    star join optimization(creation of cartesian products plus the
    nested loop join),
    hash joins(7.3).
    > Parallel Anti-Joins : NOT IN(7.3).
    > Parallel Summarization(CREATE TABLE AS SELECT) :
    query and insertion of rows into a rollup table.
    > Parallel Index Creation(CREATE INDEX) :
    table scans, sorts, index fragment construction.
    3. Q) Release 7.2와 7.3에서 추가된 optimization 기능에는 어떤 내용이 있습
    니까?
    A) 다음과 같은 기능들이 있습니다.
    1> Direct Database Reads
    Parallel query 프로세스들은 필터링이나, 소팅, 조인과 같은 작업을 수행하
    기 위해서는 아주 큰 테이블을 scanning해야 합니다. Direct Database Reads는
    read efficiency와 성능의 향상을 위해 contiguous memory read를 가능하게 해
    줍니다. 또한, concurrent OLTP와 같은 작업을 수행시 따르는 경합을 없애기 위
    해 버퍼 캐쉬를 bypass합니다.
    2> Direct Database Writes
    Parallel query 프로세스들은 intermediate sort runs, summarization
    (CREATE TABLE AS SELECT), index creation(CREATE INDEX)과 같은 작업의 수행
    결과를 디스크에 종종 기록해야 합니다.
    Direct Database Writes는 write efficiency와 성능의 향상을 위해 direct
    contiguous memory로 하여금 contiguous disk writes를 가능하게 해줍니다.
    또한, concurrent OLTP 작업과 DBWR 프로세스에 의한 경합을 없애기 위해 버
    퍼 캐쉬를 bypass합니다.
    결론적으로, Direct Database Reads와 Writes는 concurrent OLTP와 DSS 작
    업에 따르는 복잡한 부하를 조절하면서 Oracle 7 서버를 분리된 형태로, 또한 최
    적의 튜닝을 가능하게 해줍니다.
    3> Asynchronous I/O
    Oracle 7은 이미 sorts, summarization, index creation, direct-path
    loading 에 대한 asynchronous write 기능을 제공하고 있습니다.
    Release 7.3부터는 보다 나은 성능의 향상을 위해 asynchronous read-ahead
    기능을 제공하여 최대한 processing과 I/O의 병행성을 증가시켜 줍니다.
    4> Parallel Table Creation
    CREATE TABLE ... AS SELECT ...와 같은 구문을 제공하여 상세한 데이타를
    갖는 큰 테이블의 조회된 결과를 저장하기 위해 임시 테이블을 생성합니다.
    이 기능은 보통 intermediate operation의 결과를 저장하기 위해 drill-down
    분석을 할 때 사용됩니다.
    5> Support for the Star Query Optimization
    Oracle 7은 수행 속도의 향상을 위해 star 스키마가 존재하고, star query
    optimization을 invoke합니다. Star query는 먼저 여러 개의 작은 테이블을
    join하고, 그런 후에, 그 결과를 하나의 큰 테이블로 join합니다.
    6> Intelligent Function Shipping
    Release 7.3부터 parallel query를 처리하는 coordinator 프로세스는
    non-shared memory machine(cluster 또는 MPP) 내의 노드들을 처리하기 위해
    디스크나 데이타들 간의 유사성에 대해 인식하게 될 것입니다.
    이 사실에 근거하여, coordinator는 data들이 machine의 shared
    interconnect를 통해 전달될 필요가 없다는 점에서, 특정 node-disk pair로 수
    행되고 있는 프로세스들에게 parallel query operation을 지정할 수 있습니다.
    이 기능은 연관된 cost나 overhead없이 'shared nothing' 소프트웨어 아키텍
    쳐의 잇점을 제공하면서 효율성과 성능, 확장성을 개선할 수 있습니다.
    7> Histograms
    Release 7.3부터 Oracle optimizer는 테이블의 컬럼 내에 있는 데이타 값의
    분포에 관한 더 많은 정보를 이용할 수 있습니다. Value와 상대적 빈도수를 나타
    내는 histogram은 optimizer에게 index의 상대적 'selectivity'에 관한 정보와
    어떤 index를 사용해야할 것인가에 관한 더 좋은 아이디어를 제공해 줄 것입니다.
    적절한 선택을 한다면, query의 수행시간을 몇 분, 심지어 몇 시간씩이나 단축
    시킬 수가 있습니다.
    8> Parallel Hash Joins
    Release 7.3부터 Oracle 7은 join 처리시간의 단축을 위하여 hash join을 제
    공합니다. 해슁 테크닉을 사용하면 join을 하기 위해 데이타를 소트하지 않아도
    되며, 기존에 존재하는 인덱스를 사용하지 않으면서 'on-the-fly' 라는 개념을 제
    공합니다.
    따라서, star schema 데이타베이스에 전형적으로 적용되는 small-to-large
    테이블 join의 수행 속도를 향상시킬 것입니다.
    9> Parallel UNION and UNION ALL
    Release 7.3부터 Oracle 7은 UNION과 UNION ALL과 같은 set operator를 사
    용하여 완전히 parallel하게 query를 수행할 수 있습니다. 이러한 operator를 사
    용하면, 큰 테이블들을 여러 개의 작은 테이블의 집합으로 나누어 처리하기가 훨
    씬 쉬워질 것입니다.

    P.S. I have checked the CD rom itself by doing the installation in our classroom on a Windows XP Pro machine and it loaded like a charm. I have been emailing and calling Compaq customer support on this issue, and I've done everything they've suggested, including a Quick Format of the hard drive. I am still getting the same results. I have been able to load a small program (Palm Desktop) on the Compaq without a problem, so I don't think it's the CD drive that's the problem, either. Thanks for any help you can give me!!! Deborah
