How oracle.exe uses cpu

Hi all,
Does anyone know how Oracle 10g uses CPU on windows OS?
I'm interested to know is the oracle responsible for load balancing across the CPUs or OS do that.
Is there some Oracle technical documentation?
Thanks.

The OS handles CPU scheduling, not Oracle.
All of the Oracle docs can be had at http://docs.oracle.com

How oracle is used in Essbase

Hi
I just want to know how oracle is used in Essbase, to what extent it is used.
Do i need to write procedures ,triggers....... in essbase.
Krishna

Oracle and/other relational systems can be a source of data for Essbase databases, but the data is not currently shared between Oracle and Essbase. Data is extracted from Oracle (tables and views) and loaded into Essbase. Essbase has it's own database to store the data. Depending on how it is loaded, the source system can also be used in a "Drill through" situation to get more detail than the Essbase database holds. Oracle can also be used as a repository for some of the companion products of essbase to hold "system" data. Things like report definitions, screen format, users, etc.

Oracle.exe using 100% when loadjava

I have a problem when loading a jar file that pause at resolving stage for a long time. This is because the oracle.exe to use up 100% system resource. Could anyone tell me how large the jar file have to be inorder to avoid it? I had try to restart the system and it work only for one jar file after that my second jar file lead to the same problem again.

I upgraded to iTunes 10.5 on XP and now it and applemobiledeviceservice.exe use 100% CPU. How do I fix this?

I upgraded to iTunes 10.5 on XP and now it and applemobiledeviceservice.exe use 100% CPU. How do I fix this?

When I called Apple Support to ask about the 100% CPU usage, they wanted to charge me because my Ipod was out of warranty. I insisted on talking to someone and finally got to talk to a software engineer for free. He said that he had never heard of the problem in his three years at Apple. Nonetheless, he sounded really interested and suggested that it might be a conflict with anti-virus software. I deleted the antiviruse and that DID NOT HELP AT ALL.
It seems as if Apple could care less. There is no official response. Their primary response is to look at the Forum. At least you find out that the problem isn't your fault, it really is Apple!!!!
So far the best solution is just to delete iTunes and use Mediamonkey to sync your pod.
Apple, please fix this!!!!!

Oracle.exe consuming 100% CPU on windows and database hang

Hi all,
every time my oracle database is hanging when the application run, the problem is the oracle.exe consum 100% CPU but not memory and the server hang and the dabase is going to inaccessible, we need to restart oracle instance service or server to bring the databas eback to normal but it's not permanent because the problem occurs once the application turn on.
Checking the log file i found the below error every time:

Is this a new application on this database?
Has it run well in the past?
I have had this happen before on a 32bit Windows server. Our problem was a poorly written procedure that kept pegging the cpu to 100%. You should be able to figure out what SQL is being used that is causing this problem, it will be the Top Working SQL most likely.
I also had this problem on a Logical Standby server which was trying to apply SQL to the SYS.AUD$ table. As soon as SQL Apply was started, the CPU went to 100%. Once I truncated that table, the cpu usage went back to normal. Not sure what you are using to monitor your database but if you can, try to find out what SQL is running when your CPU goes to 100%.

How to find memory taken by Oracle processes using top command

I wanted to know how to find the memory taken by Oracle processes using top command. The output of the top command is as follows as an example:
Mem: 16436072k total, 16215708k used, 220364k free, 395128k buffers
Swap: 25165816k total, 1168288k used, 23997528k free, 13366520k cached

5199 oraprod 16 0 6745m 1.1g 1.0g S 0.0 6.8 2:51.23 oracle
The different Oracle processes could be Oracle database, Oracle listener, Oracle enterprise manager etc.
I hope, my question is clear as to how to find the memory taken by a process using top command.
Please revert with the reply to my query.
Regards

a short and correct answer would be: you can't.
As oracle uses a fair amount of shared memory, and that shared memory is attached to most of the oracle processes, the same memory appears a number of times.
you should rephrase your question / what is it you want to achieve?
you can ask oracle how much memory is assigned to it, v$sga, v$sgastat, v$process (for PGA). moreover, you as DBA are the one who configured that.
you can look at major an minor faults per process to see what is causing the paging (if you have any).
you can also look at the /proc/pid/statm pseudofilesystem for your oracle pids.

New x301 - Taskmgr.exe uses "constant" amount of CPU. My t60 does not why?

When I click on "Start Task Manager" I notice that even with ALL programs closed, the only process to use CPU between 2% and 10% is the Task manager (taskmgr.exe).
I also have a t60 (xp pro sp3) and noticed that task manager users 0% CPU. I know its not absolute zero but not enough to count as 1% and does not kept using up CPU.
This is my first 64 bit system. It's 1.4 dual core with 4gb ram and 128gb solid state drive.
Why is taskmgr.exe using up so much CPU %? How can this be fixed?
Anyone else with an x301 or 64bit lenovo with this similar behavior?
Thanks

anyone?

If your still having beachball issues, what I suspect has occured (which a lot of people mistakenly do) is the hard drive got sectors damaged when the computer was moved/bumped while it was in operation.
The fix for this (and anything else) is rather drastic, all user data off the Macintosh HD will have to be removed, the entire partition Disk Utility > Erase with Secure Zero (or middle selection option), OS X reinstalled and updated, programs reinstalled and files returned.
If one has a previous uneffected bootable clone or TimeMachine backup that can be used to restore.

How to get resultset from oracle procedure use ejb3

how to get resultset from oracle procedure use ejb3
i know oracle procedure should like this
Create or replace PROCEDURE resultset_test(
aaa IN NUMBER,
bbb OUT sys_refcursor) ....
but what s the ejb3 scripts looks like? please give me an example or link~
ths

- there are no EJB3 scripts, only compiled application code
- the part of the EJB spec that deals with databases is called the Java Persistence API, but likely you are just looking for the JDBC API.
Now you should know what to Google to get your "example script": "java jdbc oracle procedure"

How to prevent Oracle from using an index when joining two tables ...

How to prevent Oracle from using an index when joining two tables to get an inline view which is used in an update statement?
O.K. I think I have to explain what I mean:
When joining two tables which have many entries sometimes it es better not to use an index on the column used as join criteria.
I have two tables: table A and table B.
Table A has 4.000.000 entries and table B has 700.000 entries.
I have a join of both tables with a numeric column as join criteria.
There is an index on this column in table A.
So I instead of
where (A.col = B.col)I want to use
where (A.col+0 = B.col)in order to prevent Oracle from using the index.
When I use the join in a select statement it works.
But when I use the join as inline view in an update statement I get the error ORA-01779.
When I remove the "+0" the update statement works. (The column col is unique in table B).
Any ideas why this happens?
Thank you very much in advance for any help.
Regards Hartmut

I think you should post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your query resp. update statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Usually if you're using the CBO (cost based optimizer) and have reasonable statistics gathered on the database objects used the optimizer should be able to determine if it is better to use the existing index or not.
Things look different if you don't have statistics, you have outdated/wrong statistics or deliberately still use the RBO (rule based optimizer). In this case you would have to use other means to prevent the index usage, the most obvious would be the already mentioned NO_INDEX or FULL hint.
But I strongly recommend to check in first place why the optimizer apparently seems to choose an inappropriate index access path.
