Oracle 9i is not using RAM

Hi,
I am working on Windows Server 2003 R2 , it contains 32GB RAM. Oracle 9i R2 is installed on it but it is not using more than 150MB of RAM. How i can fix this problem because my applications and other huge stored procedures are not getting memory.

How to not display nodes in a tree if Oracle roles are NOT used?

How to not display nodes in a tree if Oracle roles are NOT used?
We don't use Oracle DB roles to grant users access to Forms from the menu. We use a template and role system of our own. Basically a few tables with templates and roles.
We want to convert our normal Forms menu to a tree menu and one of our key requirements is that when the tree is populated ONLY nodes with programs (i.e. forms) he has been granted to execute is shown.
Since we don't use Oracle Roles how to do this in a tree?
I created a function to show/hide LEAF nodes, BUT problem is that there are sub-menu nodes showing even if the leaf-nodes under it has not being displayed. My function has suppressed it.
My tree query is like this:
SELECT
     t.status, LEVEL, t.label, t.icon, t.node VALUE
FROM
     tma_tree_menu t
WHERE
tma_authenticate_sys_chk_role(USER, t.node) = 1
CONNECT BY
     PRIOR t.node = t.master
START WITH
     t.MASTER IS NULL
ORDER SIBLINGS BY
t.position
The tma_authenticate_sys_chk_role will return 1 only if the user has access to the form under that node.
I tried the FTree functions in Forms but even that has nothing.
Any help would be greatly appreciated.

Would you share the source code? I guess what I need is how exactly you retreive the user credentials from the DB table and set that boolean variable.
and then how to condition it in UIX?

Photoshop CS4 does NOT use RAM as scratch disk

Photoshop CS4 does NOT use RAM as scratch disk
as far as I can tell.
I have 20 GB RAM and still Photoshop uses the hard disk as scratch disk.
(OS = Win 7 64).
Can I force the use of RAM as scratch disk?
/Larry

Hi PECourtejoie,
I really try to understand this, please.
I don't know if 'Hitting the hard disk brings unacceptable slowdowns in my workflow'.
Because I don't know what unacceptable slowdowns are.
Any operation in Phshp takes time, and you always want it to go as fast as possible..
I know that if Phshp only worked against RAM instead of constantly saving to (and reading from) the hard drive it ought to go faster.
But I still don't know if this is the case, because there is a constant use of a tempfile on the hard drive's Scratch disk!
So far I understand that Phshp may BOTH work in RAM AND save data to the hard drive Scratch disk.
It could be possible that the writing to the hard disk happens when Phshp is idle from other tasks and that the reading only happens when data has disappeared from the Cache in RAM.
That could be a scenario where a Scratch disk on Hard drive doesn't interfere with Phshps performance, and an explanation why we should not bother about the Scratch disk on the hard drive.
But I would very much like to have some confirmation on this, IF this is the explanation of how the Scratch disk on a hard drive works without influencing Phshp's performance??
Everybody just seem to assume that Photoshop uses (some) parts of RAM as work space - I just need a better understanding of this. And some correct descriptions.

Is there a way to hibernate tab groups so that they do not use RAM memory?

Is there a way to hibernate tab groups so that they do not use RAM memory? I have a lot of tabs open and have organized them into tabgroups but my computer still uses a lot of the RAM on mozilla. Can I hibernate some of the tabgroups in any way?

Photoshop CS4 not using RAM

I'm aware that Photoshop CS4 (Mac) is a 32 bit application and therefore limited to 4 GB of RAM.
My Mac (OSX Lion) has 8 GB of RAM. So I would expect Photoshop to use 4 GB of it, but in the preferences dialogue it only lists 3072 MB "available" RAM, and even suggests to only use 1689 – 2211 MB of it. (Obviously Photoshop assumes that the Mac has not more than 4 GB of total RAM and that the user must be protected from allocating too much RAM to Photoshop.) But although I told Photoshop to use at least those 3072 MB which it assumes to be available, it doesn't even do that: According to the activity monitor, no matter how big a file is and how low the "efficiency" drops, it never uses more than 2.45 GB of RAM.
What's going on? How can I make Photoshop to use at least those 3072 MB? Is there a trick to make it use the full 4 GB which it should be able to see?

While the address space available to a 32 bit application is theoretically 4 Gig, the reality is that the OS takes a lot of space, plus the space taken by loading the application binaries and OS library code. That leaves around 3 Gig available. After working for a while, the address space gets fragmented -- 1 Gig total might be available, but it's scattered in 1 Meg pieces around the address space so you can't really allocate a large buffer. And as you work, the OS consumes more address space for it's purposes and Photoshop frees up space as needed.
If Photoshop uses all the available address space, then the MacOS code will start crashing because it assumes that it will always be able to allocate more memory. And many third party plugins assume that they'll be able to allocate large chunks of memory, and tend to crash when they can't. So Photoshop can't safely use 100% of the available address space (hence the preference).
All in all, what you're describing sounds normal for a 32 bit application.

Aperture not using RAM?

I'm wondering how I can speed Aperture up a little, it seems pretty slow.
One thing I've noticed is that Aperture (2.14) doesn't use much RAM at all - I have 16 GB of RAM in a Mac Pro, approximately 200K referenced images on a RAID that is separate from the system drives. When I load more images or do an action where the system gives me the beach ball, Aperture uses less than 1GB of memory and usually far less.
Any ideas?

In my experience with aperture 3, the program uses as much RAM as it needs, but it also seems to try and avoid swapping if possible.
On my mac pro with 18GB of ram, I've seen it use up to about 6GB while zooming in on a heavily brushed 5d2 raw file. This exact same process on my macbook pro with 4GB of ram didn't really go past 3 GB of ram usage.
To answer your original question on how to speed it up - Upgrade to aperture 3, and 10.6.3 if you haven't already. Since you use referenced masters, the upgrade will be less painless. Just create a blank aperture 3 library and use File->Import library to Copy your current aperture 2 referenced library. It will import it and leave the original in tact.
You can do this with the trial version even to test it out. A 200K referenced library in aperture 3 should be about 80GB. Just be aware that switching back and forth between v2 and v3 will probably require manually deleting preferences and preset files each time you switch versions.
And you'd probably want to disable faces and auto preview generation during import too.

I assume you have Windows on the client. The "Drivers" page of the ODBC_DSA should list all installed drivers. You require:
name= Oracle ODBC Driver
version= 8.01.07.00 (or something similar)
company= Oracle Corporation DO NOT USE the Microsoft one.
If this does not show, then either it was not included in the Oracle Client installation or you have not rebooted after the Oracle Client installation; the ODBC driver is not visible until rebooted.

note: BPEL keeps it's own "offline" copy of table and database items. A column that is marked not null in the database can be marked as nullable in this area. (if you kmow that a trigger is going to cater for this ..)
One workaround is to use a trigger to provide value rather than use the column default ..

Indexes not used in Oracle 8i

Hi Everybody,
Does anybody know how can i know which indexes are not used in our Oracle 8iR3 Database.
We need to purge as soon as possible all indexes not used
in our Datawarehousing system because they're growing and growing.
I know there's some mechanism in Oracle 9i to query which are unused is it possible to simulate something similar?
Kind regards and thank you in advance.

Are you asking about index monitoring in 8i? One way (and there aren't very many at all) of doing this is to collect (query them out of the DD) execution plans and scan those for index usage.

Could not use the Brush tool because there is not enough RAM? Photoshop CS6?

That and I couldn't even save a project I was working because (There was not enough RAM)
My computer is running Windows 7 with 4 (3 usable) GB Ram, Pentium Dual Core; @ 2.00 Ghz
-I have allocated all possible RAM to CS6
-I set 6 scratch disks (the first two are 1TB external HDD)
-I fixed the file peeling so that there is quite a bit of it
- I have Photoshop CS5 still installed (it works fine) as well as Elements 9, I don't know if that could be a problem or not.
I like the new features of CS6 especially the new 5000 px brush, but half the time I can't even use it because of this problem! What can I do to fix it?
I mostly use it for digital art so the pictures get to be at most 5000-3300 pixels. I get the problem mostly when I use brushes at 5000 px. CS5 works just fine and it uses the scratch disks I emplace, it seems as though CS6 doesn't even use them.

Obviously, you are running Win7 32-bit OS. Is that correct?
What are the full specs. of your Windows Virtual Memory, the Page File? What is its size, location, and is it static, or dynamically managed?
With a 32-bit OS, I would set the Page File to a fast, internal, physical HDD, set it to be statically managed, and size it to about 2.5x the installed RAM (~ 10GB in your case, and with a 32-bit OS).
That should provide more resources, and by being statically managed, save you CPU cycles too.
I also agree that you do NOT want to allocate all RAM to PS, as the OS needs some too. That will be counter-productive.
Good luck,
Hunt

HELP: Premiere Pro CC not using all CPU and RAM during rendering and export

Hello,
I am using Premiere Pro CC on a Windows 7. My timeline is quite simple with two videos, one with the movie (mpeg) and the other with the subtitles (avi).
When I render the sequence in PP or export, the rendering time is way too slow and it only uses around 15-20% of the CPU and 3 GB of RAM.
My hardware config is :
- CPU : i7-4770k 3.50Ghz
- RAM : 8 GB
- Disk : 2 x 3 TB SATA (no raid)
RAM is not the bottleneck, neither the disk access.
I have tried rendering and exporting the same project on an iMac (with an i5 2.7 Ghz and 4 GB RAM and only 1 disk) and the result is 4x faster !!!
The CPU usage is close to 100% as well as RAM usage.
So how come PP uses all resources availble on an iMac and not on a Windows 7 ?
Is there any known bug or software bottleneck on Windows 7 ?
My machine is brand new and nothing much installed besides Adobe products.
Any help is very much appreciated.
Thanks,

I just rendered out a a 2 minute sequence with about 100 clips in it and Colorista effects on everything to the Vimeo 1080 H264 preset. It took about 5 minutes to render straight from Premiere, it used all the recourses it could, my CPU was running at near %100, same with my ram and GPU, I was happy.
Then I did another render with Red Giant Denoiser and it now wants to take 30 mins and it is only using about %20 of the recourses available. My problem isn't that its taking longer with Denoiser but that its not using all of my computers CPU and GPU.
Im rendering at maximum render quality and bit dept to H264 (Im happy to wait the extra time), if I try to use VRB 2 it encodes 1 pass at a time and wants to take up to 40 minutes.
I would appreciate some advice on this.

After Effects not using free RAM?

Hi there
Just like to ask question regarding after effects and ram usage.
I remember before I installed the app Memory Booster - that allows you to keep track of how much ram, there was a healthy use of RAM there from after effects.
But i noticed today, whilst rendering and doing background cache rendering, the free RAM still available stays at around 4GB and I am wondering why it's not using this free RAM to help faster rendering?
this is my current multi-processing/ram settings on AE- essentially it should be using up to 6.5 GB of RAM as i allocated as I need faster rendering? Just wondering why it's staying stuck at around 3-4GB of free RAM on my system when it could clearly be used by AE. I want AE to use the RAM as it is the only running program on my system when i work!
Memory Booster down to 3.18GB with one safari tab open for Adobe forums, when exiting, it jumps back up to 4GB free RAM
Confused!
Thanks

Different projects, different footage attributes, different AE features used, different effects used, different delivery specs....
...are you comparing apples to apples, or apples to ORANGES? We don't know that.

Why index is not used if oracle have to do implicit conversion?

my db version: 10gR2
I created bitmap index on each of the column used in below sql.
the datatype of all three columns are VARCHAR2,
while i am using NUMBER in the query, which means oracle needs to do the implicit conversion before running the sql.
the problem is that, when I use NUMBER as below, execution plan will not use bitmap indexes at all.
but when I use STRING instead, it will make use of those bitmap indexes.
select FI_YTD,1,2,FI_KPI_ID
from DM_F_FI_ALL_KPI
where
    FI_KPI_ID=4140
    and FI_PERIOD=201012
    and FI_ORG_ID=10000000;So, I wonder why? how the implicit conversion affects the access path?
