Allocate more cpu

We have a test server that has 1 database.
OS: Win2k3
DB: 10gR2
We have a handful of users or less on that test server at any given time. I am running a query against a huge view (about 50 million records); and it's taking forever. The host CPU utilization is only ranging at 11% - 13%.
resource_limit on the database is FALSE. No profiles limiting resources were created on test server.
No one is using the machine right now and it's driving me nuts to think I can only utilize 11-13% of the machine's brains.
So, my question is,
1) will allocating more cpu utilization (especially when no one else is using it) improve my query run-time?
2) if so, how do I do it?

How can i allocate more RAM for my onboard video card on a 2011 macbook pro 13 inch running windows 7 via bootcamp

I noticed that since Macbooks.. macs in general use an EFI instead of BIOS. . .. Now i need to allocate some more RAM for the onboard video card since its currently running with an estimated 50mb.. I would like to increase this to 512 and cut the 3.95 down to 3.5 MB for the rest of the system ( allowing me to run more graphic intensive games and the such ... ) I know this could slow down the entire system.. ( i am aware of this ) and have gotten a 3rd party application to control and close out uneeded processes during gaming.. I just need more ram for my onboard video card.. Any help?

You don't allocate more RAM towards your video card, you put more RAM into the machine and hopefully some machines will bump the CPU graphics RAM allocation up a little.
The problem is you bought a integrated only graphics computer, if you want to 3D game you need a dedicated graphics computer with it's own or dedicated VRAM.
If your this serious about 3D gaming, your on the wrong platform.
Get a Windows 7 64bit i7 8GB RAM expandable 3D gaming tower with a good power supply and video card upgrade path, this way every few years you buy and stick in a new video card to play the latest games.
Mac's are not gaming machines and never will be because they would last too long if we could upgrade them.

How do I allocate more system resources to a program?

I have a large spreadsheet that is very slow
I wanted to allocate more of my sysyems resourses to enable it to crunch the data quicker
I have upgraded to 8G of Ram and have the highest CPU available

There is no explicit way to do this. Programs request all the resources they need, and the system provides what is available. Lion manages system resources very efficiently.
To ensure the program can use what it needs, quit all other programs that may be running (this includes your login items as well as any third party kernel extensions that you may have installed), and ensure you have adequate free space on your hard disk. That's all you can do.

How do i allocate more memory to my iphoto application? i am unable to add more photos to my library i keep getting a pop up saying not enough memory in my application

how do i allocate more memory from my hd to my iphoto application? i have over 80 gb on my hard drive, but only 1.7 gb allocated to my iphoto application & i am unable to add more photos to my library. i keep getting a popup that says not enough application memory.

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
A long-running process with a memory leak (a kind of bug)
Not enough memory for your usage pattern
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 ("Mavericks.") The procedure may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, remove the software. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

How to allocate more ram to T410 IntelHD graphics? CONFUSED

Hello There
I have a T410 Thinkpad, and I would like to know how to allocate more ram to the IntelHD graphics so that I can run my video games a lot better. I have searched through the bios and cannot find how
Sorry for my English

While sync : can't allocate more memory !!!(WCE)

Hi All,
I'm synchronizing (/Orace/mSync.exe) several MB of data (not much more of 10 MB) on a CASSIOPEIA E-200 (64 MB) with a SD Card extension of 128 MB. While synchronizing, main memory decreases dramatically (main memory, not external memory) and finally i get the message:
-2000 can't allocate more memory -2000:0
Other synchronizations with a smaller amount of data are working ok.
It is posible for a sync of ~10 MB to drain >40MB of main memory?? !!
By now, i'm using the SD Card directory to store the synchronized client DB, but this is not enough to solve the problem.
I think that temporary files and processes on main memory are involved in this problem. It is posible to use memory cards for this??
Some ideas????
Thanks in advance.
Andris

Humm,
I think the problem may be the size of a single table replication.
The replication of 10000 registers from this table is working ok, but replicating 25000 i get the error ("Can't allocate more memory").
Anyone knows a limitation in the number of registers or size of a table replication????!!!
Thanks!!
Andris

Use V$SESSTAT to determine which sessions are using most CPU, and investigate what SQL these users/sessions are executing:
SQL> select ss.sid, se.command, ss.value CPU, se.username, se.program
from v$sesstat ss, v$session se
where ss.statistic# in
(select statistic#
from v$statname
where name = 'CPU used by this session')
and se.sid=ss.sid
order by ss.value desc;

RMAN parameters - to use more CPU for Backup & Restore

Hi Friends,
I am using RMAN backup on 11g database on windows.
RMAN is taking almost 1 hr to restore the database and i could see the CPU usage is very less - less than 10% during restore.
so how can i make the RMAN backup and restore faster by using more CPU on windows.
Regards,
DB

Even better, check the wait events in your database and you'll know why the backup / restore is not as expected.

Urgt:How to identify TOP 5 SQL using more CPU time without using statspack

How to identify the TOP 5 SQL queries which are consuming more CPU time during the timespan of 24 hours for entire database. There are N number of users who have issued sql queries, out of which few users have disconnected and few user are still connected to the database(I need to consider all sessions). My database version is 9.0.1. I don't want to use statspack. Is there any way to identify TOP 5 SQL consuming more CPU time without affecting the performance of the database. Can any one help me on this? Its urgent!!. I don't want to use statspack becasue it degrades the performance and i cannot afford to run it for 24 hours.

You don't run statspack for 24 hours, that would infact be pointless...
Run statspack for say a 10 or 15 minute window during a particular "busy" period on your database. If you run it for longer then all the useful data will have been "averaged out". You want a snapshot in time, not an average over the day.

Particularly in your case statspack is the best.

Higher response time after adding more CPU

Hello all,
have you ever experienced that after incresing SAPs (adding 2 more CPU + 4 GB of memory) on the VMware ESX 3.5 the DB response time went from 150 to 400-500 ms ? NO DB parameter were changed. In app server, only extended memory and program buffer were enlarged.
We are running ECC6 system on MAXDB 7.6.6.3 (SLES9). MAXCPU is set to 1
Any idea ?
Thank you.
Pavol

> We are running ECC6 system on MAXDB 7.6.6.3 (SLES9). MAXCPU is set to 1
I'd always set MAXCPU to the number of physical CPUs/cores you have. It's VERY unlikely that the database will use more CPU than the application.
The database can't scale, if one CPU is used other requests have to wait.

How to find which query taking more cpu

Hi,
How to find which query taking more CPU
at a particular point of time .
Chhers,

Take a look at Server Standard Reports. It has a few CPU usage oriented reports.
You can also track CPU usage by server-side tracing:
http://www.sqlusa.com/bestpractices/createtrace/
Glenn Berry's CPU usage query:
SELECT TOP(25) p.name AS [SP Name], qs.total_worker_time AS [TotalWorkerTime],
qs.total_worker_time/qs.execution_count AS [AvgWorkerTime], qs.execution_count,
ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second],
qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count
AS [avg_elapsed_time], qs.cached_time
FROM sys.procedures AS p WITH (NOLOCK)
INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK)
ON p.[object_id] = qs.[object_id]
WHERE qs.database_id = DB_ID()
ORDER BY qs.total_worker_time DESC OPTION (RECOMPILE);
