Tablespace creation with different block size

OS - rhel 4.3
kernel - 2.6.9
Oracle - 10.2
Hardware - IBM X series 346.
Defined block size for the db - 8kb.
Question: Can I create a tablespace with 16k?
regards,
Lily

You can create a tablespace with 16k blocks if, as Daljit suggests, you create a 16k block buffer cache.
I would, however, ask why you would want to create such a tablespace? The ability to have tablespaces with different block sizes in a single database was created primarily to allow the use of transportable tablespaces in situations where different databases had different block sizes. If you are trying to create a 16k block size for a different reason, there are a couple of things to be aware of
- While there are theories out there that tablespaces with different block sizes can have dramatic effects on performance, I've never seen any solid evidence that backs up this theory.
- Using different block sizes in the same database can significantly increase the complexity of managing a database. You'll have multiple buffer caches that you'll have to size, for example, automatic SGA management doesn't work with non-standard block size buffer caches, etc.

Database Tablespaces with different block sizes...

Hi ,
What are the pros and cons of setting different block sizes to tablespaces, and where may be this useful???
Thanks,
Simon

generally speaking tablespaces with different block sizes than the db standard are for transportable tablespaces only.
however,
Burleson will tell you to micromanage your memory allocations with multiple block sized tablespaces and various keep/recycle caches.

I think its overkill and you can most likely get performance improvements from looking at other things such as the SQL your applications are running against the db. My rule of thumb is that 70% of your performance improvements are going to come from sql tuning. You can focus on the other 30% when the vast majority of your queries use 5 LIO per row per join.

Creation of PDF with different page sizes

I am generating PDF using Acrobat Distiller from my application from the .ps file. From one machine, the PDF is generated with different page sizes.one page with 8.5*12.99 and other pages with 8.5*11 in the same PDF. However the PDF is created with correct page sizes for all the pages in another machine. The only difference between the machines is the Internet Explorer version. I am using Internet explorere 11.0 and the other machine have a version of 8.0 installed.
Why the difference in page size occured? Is there any dependency on the Internet explorer used while creating the PDF using Distiller? Any help for the issue with the discrepancy in the page sizes is really appreciated.
Thanks!

Acrobat Distiller uses the page size in the PS file. May be a problem of your application which create the PS file.

How to create a report with different page sizes

Hi,
I would like to create a report with different page sizes, it's possible to do it with diadem?
When I change the layout parameters, changes afect to all sheets...
Is there a way to change page size individually for each sheet?
Thanks in advance.
Marc

Hi Marc,
You can use the DocStart and DocEnd commands along with the PicPrint command to spool multiple print commands to the same output PDF file using the direct printer approach. This should enable you to programmatically specify the page size differently for each sheet that you add to the print job.
' Print PDF Page by Page.VBS
OPTION EXPLICIT
Dim i, Path, OldPrintName
Path = AutoActPath & "2D Stacked"
Call DataDelAll
Call DataFileLoad(Path & ".TDM")
PDFFileName = Path & " Page by Page.pdf"
IF FileExist(PDFFileName) THEN Call FileDelete(PDFFileName)
OldPrintName = PrintName
PrintName = "winspool,DIAdem PDF Export,LPT1:" ' Set to PDF printer

Creating a document with different page sizes.

I'm trying to produce a leaflet with different pages sizes. To try and explain what I mean I have included a picture of what I'd like the front cover to look like. When producing a booklet there doesn't seem to be a provision to individually alter each page size in the pages or document set up panel. Is there anyway around this or do I have to create each page seperately, export to pdf and then combine into the leaflet? Help gratefully received. tomas

The build booklet feature is for very basic booklets, not something like this.
Sorry, but you’ll need to make everything full size and then do the cutting.

How to install 10g database on windows with db block size 16k

Hi,
Can somone help me install oracle 10g database on windows xp with db block size as 16k.
i need this database, because it is one of the recommendations for insalling OWB(Oracle Warehouse Builder).
Thanks,
Philip.

1) In Initialization parameter pile
DB_BLOCK_SIZE=8192/16K - One way
2) The other way once you install Oracle 10 G then at the time when you are creating database with Database Configuration Assistant you can modify the block size by the[b] Initialization parameter screen.
- Sizing Tab
Block Size 8K/16K
*** Remember by default Oracle 10 G uses 8K block size.
You use the options on the Sizing tab to configure the block size of your database
and the number of processes that can connect to this database. The Block Size setting corresponds to the smallest unit of storage within the Oracle database. All storage of database objects (tables, indexes, and so on) are governed by the block size. The block size defaults to 8KB, but you can modify it. Once the database is created, you cannot modify this setting.
The maximum and minimum size of an Oracle block depends on the operating system. Generally, 8KB is sufficient for most transaction-oriented applications, and larger block sizes such as 16KB and higher are used in data warehousetype applications.
The Processes setting specifies the maximum number of simultaneous operating system processes that can be connected to this Oracle database. You must include at least six processes for each of the Oracle background processes. You can increase this number on the Initialization parameter screen.

Material Cost Estimate with different lot size.

What happens if the material cost estimate is run twice using different lot sizes each time (all other parameters unchanged) for the same period?
Will the cost estimate run later overwrites the results from cost estimate run earlier (though the lot size is different)? What is the role of lot size in a material cost estimate?

The costing lot size impacts your cost estimate if you have lot size independent costs (i.e. setup cost). Those fixed costs are spread over the costing lot sizee to give you a cost per unit.. Larger costing lot sizes can also help you minimize rounding issues.
You can only have one marked cost estimate in a given period. However, you can create and save a cost estimate as many times as you want as long as you have not marked it for release. When you save the estimate it will overwrite an existing estimate. You also have the option of creating multiple estimates under different versions or with different costing variants.

Loading images with different horizontal sizes

I would like to load images with different horizontal
resolutions (vertical resolution to be the same) dymanically into
an empty movie clip. I would like them to load with the right hand
side of the image lined up with the right hand side of my site. I
have seen many tutorials about how to accomplish the loading of the
movies, but I cannot figure out how to make them open with the
right hand side always lined up on the right.
To be more specific, let's say I have three images of the
varying pixel resolutions (1200x600, 800x600, and 400x600 for
example). I would like the horizontal size to always extend away
from the right hand side of the site with the right hand edge of
the images always lined up.
Is this possible to do by loading them into an empty movie
clip?
thanks

When you load an image file into an empty movieClip, that
clip takes on the dimensions of the loaded content. The
registration point for the clip is set to the upper left corner.
So, once the new image is loaded, just set that clip's .x to the
stage width - the width of the clip.

Material number for chemical with different packing sizes

A same chemical that we purchase from supplier can be in 25Kg bag, 1000kg bag and 50 kg bag. When we receive the chemicals, the physical goods of the chemical are in 25 KG Bag, 1000kg Bag and 50Kg bag store in the warehouse.
When we sell to customer, it can be in those 3 standard bag size or in KG depend the order quantity from customer.
For the above Chemical what is the best way to catalogue the material number, should it be 3 material numbers for the 3 different pack size, or 1 material number only?

you can have two solution for this with both pros & cons with one material master:
1. You can have three different unit of measure for 25KG, 1000KG & 50KG bag and you can maintain the relationship in the material master. This will help you to get the total stock in KG in your company and you can sell to the customer. Only problem is you will not be able to determine how much of each type of packaging you have.
2. You can define the material relevant for batch management. Create three batches 25KG,1000KG & 50KG, also create three different unit of measures as explained above. Now whenever you are doing the GR just put the material in correct batch, by doing this you can easily track you material along with the type of packaging. Also you can sell the material, while delivery you can use the functional of batch determination based on some log. Only problem is manual intervention which can be covered if you use some exit while doing GR so that correct batch is selected based on the Order Unit.
Hope this will help you..
Enjoyyyyyyyyyyyyy

Creating a list with different row sizes...

I'm new to AS 3.0 and CS4 and I've been getting up to speed
on all of it. I've used the List component before with my own
CellRenderer. I now need to create a list with different row
heights. The List component is great and does everything that I
want but it requires all rows to be the same height.
I'm unsure of where to go. Creating my own class seems like a
lot of work. The TileList and Grid components don't allow different
sized (and dynamically changing) row heights either. Is there some
base class (SelectableList? BaseScrollPane?) that I should extend
or do I need to just bite the bullet and write it all from scratch?
I need each row to have it's own height and interaction with
a row could change the height of the row. The main use is a list of
data. If the user clicks in an item, it turns the display into
something they can edit (which will need more height).
Thanks for any thoughts on a direction I should think about.
By the way, I really like that AS 3.0 is much more consistent of a
programming language than previous MX versions that I've used.
We're doing a lot of AS/Flash/AIR work with it and it's turning
into a wonderful environment...

Any ideas about this??

Fail to create PDF from 2 templates with different page sizes

Hi, I am having problems to create a PDF with multiple page sizes and using 2 templates. I have to create a PDF using two dynamic templates. The second template has multiple pages, some A4 some A3, which I select through subforms (A3 specific subforms are on an A3 page). So: ^job <mdf1> -zOut.pdf <fields> ^form <mdf2>.mdf ^page 2 ^group G_heading_A3 <fields> The templates on their own are ok, but when I combine them the second is always A4, even if a) the subforms are on A3 (heading_A3) and if b) the page is A3 (page 2). I couldn't find anything on the web nor in the documentation. Does anyone have a clue? Thanks, Edward

Multi-clipping with different frame sizes

I have two video clips that I would like to merge into a multiclip. Unfortunately, they have two different formats. One is an Apple ProRes 422 (1024x768), while the other one is a PAL 720x576.
As far as I know, there's no way of making a multiclip out of the two, so I'm trying to compress the ProRes into a PAL 720x576, but the result is just awful. Considering the ProRes 422 is a screen capture, any suggestion on how to obtain a high quality multiclip out of the two original tracks?
I'm using Compressor and Final Cut Pro 7.

Let's do the math…
Your ProRes contains a bit less than 800,000 pixels per frame while your PAL is only about 400,000; one of every two of your original pixels is being thrown away or smooshed into the PAL format so, yes, I imagine it looks pretty bad. You can, of course, scale up the PAL but then you are merely doubling the size of every pixel, you are ot adding any new detail or resolution.
Decisions like this are made by carefully assessing the output requirements, not the editing setup. How will you display the final piece? If you have HD playback resources and needs, you must scale the PAL up If you are going to standard def of DVD, then both of your sources are going to get smooshed into obscurity.
If you have the ability to maintain the highest rez, you can bring your 768 footage into a 576 sequence and, without scaling it so the video is cropped, move it around in sync with your soundtrack so the important part of the screen capture is visible. Export at 576. You will also need a full screen version to handle cutaways.
However, just my opinion, using multiclip for two inputs is way overkill. Easier to just edit conventionally with two tracks and a razor blade.

Can't process a batch with different page sizes. - Acrobat X Std / Windows 7 Ent. / Fujitsu-fi-6140

Unable to scan Letter and Legal pages in the same batch, the output is either all legal or letter. Need to detect page sizes and scan them as what they are into a single PDF file.

Please help.

Hi Test Screen Name,
While reproducing the problem I realized I was in error as to how far in the sequence the problem occured. I actually do get as far as batch creating PDF,. The only difference there is that I can no longer "drag and drop" files in the batch create window. I have to use the "Add files..." command in the upper left of the batch create window.
So, the application batch creates the files. Afterward, I use the Action Wizard to batch "Password Protect" the files. It is during this command run that the error occures. (Note: I am trying to save over the old files by having them save to the same directory under the same name, just like I used to be able to do.) The error I get is:
Action Completed.
Saved to: \\HOME\path-to-original-files\
Warning/Errors
The file may be read-only, or another user may have it open. Please save the document in a different
Document: Name of document1.pdf
Output: Name of document1.pdf
The file may be read-only, or another user may have it open. Please save the document in a different
Document: Name of document2.pdf
Output: Name of document2.pdf
The error message loops through all the documents. I don't have the documents open or in use. By default they shouldn't be "read-only". This all did not occure when I previously used the application with Windows XP.
I have not yet tried saving them to a different directory. I will try that later today. (I didn't want to have a lot of versions of the same documents, it tends to be confusing.)
Thank you for your reply,
TPK

Save FrameMaker Book as PDF - Files with different page sizes

I've created a book with 2 files - the pages in the first file are 8.5 x 11, the pages in the second file are 8.5 x 14.
How can I save the book as a PDF but keep both page sizes? Right now if I change the page size in the PDF settings dialog, it changes all pages.
Thanks.

Something's not right. Try this route then:
1. Use the Print Book option and have the AdobePDF printer instance selected, turn off the the Print to File, enable the "Generate Acrobat Data" option.
2. Click the PDF Setup button to ensure that the Page size is set to the largest (as in the previous message),
3. Then click the Setup... button to configure the printer for the largest size required.
4. Then click the OK button to get back to the Print Book and finally click Print.
5. You should be prompted where to place the file (unless you left the default configuration which may place it on your desktop).
This should have all the pages correctly cropped as in the following sample with Letter, Legal and Tabloid all in one book:
