DB_KEEP_CACHE_SIZE suitable size
I am using an Oracle 10g Release 1 database and was wondering if anybody has any suggestions on how one can investigate if it is appropriately sized ? The current setting in our environment is 1 Gbyte. We have a very large table 100 Gbyte , which contains LOB data where the KEEP option has been set (ALTER TABLE KEEP).
I am looking for ways to investigate if the current setting of 1 Gbyte is appropriate ?
That is depend up on the size of memory available and tables to be in Keep cache
if you donot have less menory in keep than the table soze .. table will be on memory+disk
Please go through the Doc ID: Note:257643.1

Table size exceeds Keep Pool Size (db_keep_cache_size)
Hello,
We have a situation where one of our applications started performing bad since last week.
After some analysis, it was found this was due to data increase in a table that was stored in KEEP POOL.
After the data increase, the table size exceeded db_keep_cache_size.
I was of the opinion that in such cases KEEP POOL will still be used but the remaining data will be brought in as needed from the table.
But, I ran some tests and found it is not the case. If the table size exceeds db_keep_cache_size, then KEEP POOL is not used at all.
Is my inference correct here ?

Does it mean that if the db_keep_cache_size < table size, there is no caching for that table ?
Or am I missing something ?

Many thanks for your response.
Here is the test I ran;

Private strand flush not complete how to find optimal size of redo log file
hi,
i am using oracle 10.2.0 on unix system and getting Private strand flush not complete in the alert log file. i know this is due to check point is not completed.
I need to increase the size of redo log files or add new group to the database. i have log file switch (checkpoint incomplete) in the top 5 wait event.
i can't change any parameter of database. i have three redo log group and log files are of 250MB size. i want to know the suitable size to avoid problem.

umeshHow often should a database archive its logs
Re: Redo log size increase and performance
Please read the above thread and great replies by HJR sir. I think if you wish to get concept knowledge, you should add in your notes.
"If the FAST_START_MTTR_TARGET parameter is set to limit the instance recovery time, Oracle automatically tries to checkpoint as frequently as necessary. Under this condition, the size of the log files should be large enough to avoid additional checkpointing due to under sized log files. The optimal size can be obtained by querying the OPTIMAL_LOGFILE_SIZE column from the V$INSTANCE_RECOVERY view. You can also obtain sizing advice on the Redo Log Groups page of Oracle Enterprise Manager Database Control."

Render file size bigger After Effects CC 2014
Hello, this seems like a silly question, but ever since the 'After Effects CC 2014' update my rendered files seem to be enormous in comparison to the files I rendered before the update!
I don't see why the update would have adjusted my render preferences, but it must have done as a 2min clip that rendered at 140mb before is now 10GB!!!
My knowledge of codecs and compression is limited but I had a good preset before the update which now seems to have changed (although I have always been rendering h.264/full quality/no audio so I don't understand how the file size can change so drastically).
Has anyone else experienced anything similar?
If not could you please advise me on how to render these files to a suitable size. Like I said they need to be h.264, 1920 x 1080 with no audio.
Thanks.After Effects CC 2014 no longer supports the output of many delivery codecs, such as Mpeg4 and H264, through the Render Queue.
You can output far more formats, and in greater quality, using Adobe Media Encoder. You can send AE renders directly to AME from After Effects. You can import AE projects directly into AME. And you can also render high quality and/or lossless formats from the AE Render Queue and then re-encode them from AME. -

I use ResourceBundle and *.properties files.
Each property file matched to class.getName() and located next to *.class file.
E.g.
/com/samsol/project1/LoginPanel.class
/com/samsol/project1/LoginPanel.properties
/com/samsol/project1/LoginPanel_ru_RU.properties
1. Is this propper location for *.properties files?
2. How to localize multiline messages? How and when to use "\n", "\r\n", |\n\r" for different platforms.
3. Depended on the default font size in the system I want to display icons in menu and toolbars having suitable size. How to use scalable icons?
4. How to localize the icons? Example. For "login" button somebody like to see the lock, other the key, but some the ID (passport). (This is just example). But how to do it?
5. Is there are any method to change the localization on the fly?1. Whatever you decide.
2.
3. Start from [1] and see how you can manage to use SVG for this purpose. [2] can you give some additional ideas.
5.
void setLocale(Component component, Locale locale) {
component.setLocale(locale);
if (component instanceof Container) {
Container cont = (Container) component;
for (int i = 0; i < cont.getComponentCount(); i++)
setLocale(cont.getComponent(i), locale);
}Before calling the method above, do
Locale.setDefault(new Locale(this.langCode, this.countryCode));
frame.applyComponentOrientation(ComponentOrientation
.getOrientation(Locale.getDefault()));where langCode / countryCode specify the locale you wish to set and frame is your main frame (do it for all open frames with Frame.getFrames()). In addition, you'd have to update all the localized showing controls (such as buttons and so on).
4. Change the icons inside the method above.

After having problems with Parallels I am giving Boot Camp a try.
However, the assistant only mentions Windows Vista and XP.
So which instructions should I follow? Or are there some updated ones for Windows 7.
Also, could you give me any suggestions as to the most suitable size for the Boot Camp partition.Relax. Your model more than qualifies for Win7.
Make sure you have everything square on the Mac side first with software and firmware updates. Launch Software Update and run it until nothing is left to update.
Now, it's on to the Boot Camp Assistant. Launch this from/Applications/Utilities, and follow the prompts.
Move your Windows partition slice so that you have, say, 50 GB for Windows. This can actually be any size above 40 GB. Windows 7 x86 needs about 20 GB during installation alone, though actual used space is much less once it's installed. The same applies to the x64 version, but let's give that one, say, 60 GB or more as some files may be duplicated for the two different "architectures" in that version to run concurrently.
When you've apportioned your hard disk space, get your Windows DVD out and let Boot Camp start it. If you missed this step, you can insert the DVD later and hold the C key as the Mac starts.
If your unit shipped with OS X 10.6, have your Install Discs handy. If you upgraded from 10.5, then the 10.6 upgrade DVD will do. We'll soon use either one.
During the Windows Setup process, you'll be asked to do an upgrade or custom install. Choose Custom, which will take you to a partitioning screen.
On this screen,you must click Advanced and then select the volume tagged BOOTCAMP. You will then have to click Format while this volume is highlighted. Click Yes to confirm.
Let the Setup program finish out the install, then set up your Windows account.
Since the soft-eject key at the top of your keyboard won't have a driver yet, you'll be removing the Windows disc as follows: Click Start, Computer, and then select the DVD icon. Click Eject in the upper toolbar of the Computer window.
Now, insert your Mac install disc (or 10.6 upgrade) and run the Setup file when prompted by AutoPlay. This will start Boot Camp 3.0. Follow the wizard through.
From here,you may restart in Mac OS at points in this walkthru. To avoid this, hold the Option key to bring up a boot menu, then click Windows.
Back in Windows again, run Apple Software Update to pick up any and all fixes for your new Boot Camp package. You could be doing this 2-3 times. Repeat until no required updates remain.
Do the same for Windows Update as well.
Once all updates are in, add your favorite software, and you're done.

In Photoshop Elements 1, how do I put a frame/box around some type ?
I am doing a post card and I want to find out how to put a box around some text (i.e. a text box) and then be able to alter the thickness of the line.
Go to File>new>blank file. Enter the dimensions of the card, background white (or whatever suits you), resolution 300px/in
With the rectangular marquee tool, drag out a box of suitable size. You will see "marching ants" surrounding the rectangle.
Open a blank layer at the top in the layers palette
Go to Edit>Stroke(Outline) selection. Enter the width of the stroke (try 5 px), select the color, place it inside
Type the text to be within the confines of the text box with the type tool
N.B. The advantage to having the stroke on a separate layer is that if you don't like it, you can delete the layer and replace it -

Can apple tv2 show raw photo files
Using Apple tv2 in a windows 7 home network environment. Music files and photo files (both JPEG and RAW files) stored on Synology network disk.
Typically I shoot photos in Canon Camera Raw format and store. My wife shoots in JPEG format.
We are using the screensaver in apple tv to show our photos, and it's not obvious whether I need to convert the raw files over to jpeg in order for those photos to show on the slide show when apple tv is operating.
Can apple tv display raw format photo files?Whatever iTunes does to populate the AppleTV2 with user photos I have no doubt it will not be sending the original images, only derivatives thereof - if Windows can natively decode these RAW files I suspect iTunes uses them 'As Shot' and then downscales to a lower quality compressed version to send to the AppleTV - if it did not do this AppleTV would not be able to hold many photos from modern cameras due to their resolution and file sizes which would particularly be an issue with RAW files.
AppleTV has 8GB of solid state memory - we don't know how much is available for photos and other tasks, but depending on the camera I doubt you'd get that many RAWs to it if it transferred them as is.
Bear in mind AppleTV 2 can only output 720p quality max which equates to a resolution of 1280x720 so having photos much larger than that (maybe add 50-100% to allow for zooms) is probably not going to help in terms of visual quality.
You might not want a set of redundant smaller JPGs just for AppleTV but they probably wouldn't that much space if you batch processed them to a suitable size.

Hey Harm,
In my several months without Internet, I've fallen waaaay behind in my tech reading. What's your opinion of the I/O controllers on Areca cards? What to look for, what to avoid, that kind of thing. (3 drive RAID 3 planned.)Hi Harm,
Before I ask for a perspective, I just want to thank you for all your efforts in sharing information with folks that are more novice such as myself. I have spent a lot of time in the various forums over the past 3 - 4 weeks considering a variety of perspectives related to the computer build that I am currently working on and all of your informative posts, as well as your responses to questions by others, have been EXTREMELY useful to me and the thought processes that I am currently going through. Thank you - very much!
I am formalizing my plan on the drive configuration for my new build and have decided to take the SSD plunge for the OS and Program files. Whereas I am going to buy the ASUS Rampage III MOBO (which offers SATA III), I plan to stick with Intel's X25-M G2 160GB SSD based on cost (and being a suitable size for OS/Programs) as compared with Crucial's SATA III 256 GB SSD at a couple of hundred dollars more. I'll move my old WD740 Raptor SATA drives, currently in a RAID 1 (MOBO) into the new system and use the new MOBO for a 140 GB RAID 0 scratch drive. For the media output/storage drive I have decided to invest in the Areca 1880ix-12 controller. My plans are to stand it up with a RAID 3 with 3 or 4 1 TB drives, likely Spinpoint F3s, thinking that while I will not use all the SATA III capabilities or all the 12 ports now, there will be ample capability for me to expand in the future with a SATA III-based RAID or with additional drives. (As a novice user, I don't think that I would ever exceed the limit of the board, but then again, neither did you!)
My question centers on whether to get the low profile (1880ixl-12) or the full-height (1880ix-12) controller. Looking at Areca's photo's http://www.areca.com.tw/support/photo_gallery.htm), the two cards appear somewhat different - on the low profile card there's a small fan; on the full-height card there are two large heat-dissipation/cooling fin assemblies. On the full-height board there's a large connector along the top edge that's not on the low-profile board - presumably this is some type of multi-connector or a "ganged" arrangement for individual drive connectors.
Any thoughts on:
(1) proposed drive structure, and
(2) full-height versus low-profile controller card?
In advance, thanks.

Export FCP movie for burning in iDVD
I created a 30 minute movie in Final cut pro. When I exported the file, it was 25 gig. I want to burn the movie to DVD in Imovie and obviously it was a smidge large.. What are the best and most effective settings in FCP to do this. I am new to FCP so any help is greatly appreciated.
It doesn't matter how large the file is.
Drop it into iDVD and iDVD should compress it to a suitable size for a DVD.
The only measurement that matters is the length as iDVD cannot deal with projects longer than around 2 hours. -
[SOLVED] SGA_MAX_SIZE pre-allocated with Solaris 10?
Hi all,
I'm about to build a new production database to migrate an existing 8.1.7 database to 10.2.0.3. I'm in the enviable position of having a good chunk of memory to play with on the new system (compared with the existing one) so was looking at a suitable size for the SGA... when something pinged in my memory about SGA_MAX_SIZE and memory allocation in the OS where some platforms will allocate the entire amount of SGA_MAX_SIZE rather than just SGA_TARGET.
So I did a little test. Using Solaris 10 and Oracle 10.2.0.3 I've created a basic database with SGA_MAX_SIZE set to 400MB and SGA_TARGET 280MB

$ I wasn't sure whether Solaris 10 was one of the OSs with truly dynamic memory for the SGA but had hoped it was... this seems to say different. Really I'm just after some confirmation that I'm reading this correctly.
Thanks.

Edited for clarityI don't want to get bogged down in too many details, as the links provided in previous posts have many details of SGA tests and the results of what happened. I just want to add a bit of explanation about the Oracle SGA and shared memory on UNIX and Solaris in particular.
As you know Oracle's SGA is generally a single segment of shared memory. Historically this was 'normal' memory and could be paged out to the swap device. So a 500 MB SGA on a 1 GB physical memory system, would allocate 500 MB from the swap device for paging purposes, but might not use 500 MB of physical memory i.e. free memory might not decrease by 500 MB. How much physical memory depended on what pages in the SGA were accessed, and how frequently.
At some point some people realised that this paging of the SGA was actually slowing performance of Oracle, as now some 'memory' accesses by Oracle could actually cause 'disk' accesses by paging in saved pages from the swap device. So some operating systems introduced a 'lock' option when creating a shared memory segment (shmat system call if memory serves me). And this was often enabled by a corresponding Oracle initialisation parameter, such as lock_sga.
Now a 'locked' SGA did use up the full physical memory, and was guaranteed not to be paged out to disk. So Oracle SGA access was now always at memory speed, and consistent.
Some operating systems took advantage of this 'lock' flag to shared memory segment creation to implement some other performance optimisations. One is not to allocate paging storage from swap space anyway, as it cannot be used by this shared memory segment. Another is to share the secondary page tables within the virtual memory sub-system for this segment over all processes attached to it i.e. one shared page table for the segment, not one page table per process. This can lead to massive memory savings on large SGAs with many attached shadow server processes. Another optimisation on this non-paged, contiguous memory segment is to use large memory pages instead of standard small ones. On Solaris instead of one page entry covering 8 KB of physical memory, it covers 8 MB of physical memory. This reduces the size of the virtual memory page table by a factor of 1,000 - another major memory saving.
These were some of the optimisations that the original Red Hat Enterprise Linux had to introduce, to play catch up with Solaris, and to not waste memory on large page tables.
Due to these extra optimisations, Solaris chose to call this 'locking' of shared memory segments 'initimate shared memory' or ISM for short. And I think there was a corresponding Oracle parameter 'use_ism'. This is now the default setting in Oracle ports to Solaris.
As a result, this is why when Oracle grabs its shared memory segment up front (SGA_MAX_SIZE), it results in that amount of real physical memory being allocated and used.
With Oracle 9i and 10g when Oracle introduced the SGA_TARGET and other settings and could dynamically resize the SGA, this messed things up for Solaris. Because the shared memory segment was 'Intimate' by default, and was not backed up by paging space on the swap device, it could never shrink in size, or release memory as it could not be paged out.
Eventually Sun wrote a work around for this problem, and called it Dynamic Intimate Shared Memory (DISM). This is not on by default in Oracle, hence you are seeing all your shared memory segments using the same amount of physical memory. DISM allows the 'lock' flag to be turned on and off on a shared memory segment, and to be done over various memory sizes.
I am not sure of the details, and so am beginning to get vague here. But I remember that this was a workaround on Sun's part to still get the benefits of ISM and the memory savings from large virtual memory pages and shared secondary page tables, while allowing Oracle to manage the SGA size dynamically and be able to release memory back for use by other things. I'm not sure if DISM allows Oracle to mark memory areas as pageable or locked, or whether it allows Oracle to really grow and shrink the size of a single shared memory segment. I presumed it added yet more flags to the various shared memory system calls.
Although DISM should work on normal, single Solaris systems, as you know it is not enabled by default, and requires a special initialisation parameter. Also be aware that there are issues with DISM on high end Solaris systems that support Domains (F15K, F25K, etc.) and in Solaris Zones or Containers. Domains have problems when you want to dynamically remove a CPU/Memory board from the system, and the allocations of memory on that board must be reallocated to other memory boards. This can break the rule that a locked shared memory segment must occupy contiguous physical memory. It took Sun another couple of releases of Solaris (or patches or quarterly releases) before they got DISM to work properly in a system with domains.
I hope I am not trying to teach my granny to suck eggs, if you know what I mean. I just thought I'd provide a bit more background details.

Help this newbie save her film UNSQUASHED before she loses her mind!!
I'm working on my first project in FCP v6. Managed to work out everything except how to get the thing saved at a suitable size without it being SQUASHED.
I've read just about everything I can find about this and tried all sorts of different settings. No joy. Squashed every time, and it takes about 45 minutes to save each 10 minute clip. I've been trying to do this for six weeks! HELP!
It was a mini DV clip and I need to save it for web streaming / YouTube.
I'm exporting using Quicktime conversion.
Can someone please kindly hold my hand?
THANK YOUfirst of all:
make an IN (I) and OUT (O) in your timeline for testing a 5sec clip, so you don`t have to render the whole sequence or movie again and again to test the settings we`ll try.
now a few questions:
1) is your sequence playing with the correct settings in fcp? with other words, is it be squashed before or after rendering out the movie?
2) is it 16:9 or 4:3 footage?
3) do you have the Compressor Application in your system?
4) Please right click one clip in your timeline and choose "format" or Object Settings".
Please post again with the answers....
