Hi all!

I've got one problem with CPU in Solaris 10.
Only one database, nothing except it running in Sun Sparc V890, 4 CPU, 16gb memory.

The SGA_TARGET parameter was set to 10gb, pga=2gb.

However, whenever some client retrieve data from report which was running by Oracle Application Server, both of OAS & Database 's CPU achieved to 100%. The reports statements, of course, was tuning again and again, if I ran them from sqlplus, they'd taken about 0.03% CPU per statement.

May you guide me how to limit CPU usage for oracle?
The purpose just I want to set Oracle Database will achieve only 70%-75% total CPU.

Thank you very much!

Database and OAS hosted in same server?

Thank you Mahesh Rajendran, for your reply!

Database and OAS are not in same server.
I brief them as following:
- Database in Sun Sparc V890, Solaris 10, 4 CPUs, 16gb Memory, SAN Storage 1TB, Raid 1 and Single Instance.
- 5 OAS separate instances with OC4J in 5 servers running Windows Server 2003, Linux RedHat 4 - HP Proliant ML 350, 4 CPUs, 8gb Memory per server machine.

First time, when clients retrieve data for report monthly through application in OAS, the process & virtual memory in OAS increased more and more. When them (OAS machine server's CPU) achieved 100%, the Database Machine Server's CPU will increase concurrently to 100%.

I'll give to you the log file (in both of OAS and Database) as soon as possible.

By any way, thank you!

This is a well known issue with Oracle Application servers.
Check metalink. There are too many cases with too many scenarios.
Best to open an SR.

Yesterday, we tested the report module with ~ 100 concurrent sessions in Database, ~ 750-820 concurrent session cached in OAS. And, they're .. death, both of Database, AS & Machine. In Database, I've got

Of course, I searched the error in google and metalink, some article like
Quote:

The EAGAIN error means the fork(2) failed because of a temporary resource outage. Perhaps this user had hit the limit for the maximum number of child processes. Check your:

$ ulimit -a

as this user. I would have expected a system call that returned EAGAIN to be retried until it succeeds or the process decides it has tried enough, but I don't know what the RDBMS does here.

Thank you, Swan!

I've read the article, more and more yesterday. It looks like a bug of Oracle, but still now, I've not understood why system downed.

May be I have to search continue!

It appears the actual error is an OS error.
It could be induced by Oracle bug or by Oracle init.ora value which you particular system can't correctly handle.

The various trace files
Errors in file /u02/app/oracle/admin/VNP/bdump/vnp_psp0_12072.trc
may provide clues; then again they may be a wild goose chase.

@BlackSwan & Mahesh Rajendran:

Yesterday, my database had got problem such as those above.
And I found something, especially. However, I separate one by one:

No such need content information, and then, try to search in metalink.

On 10.2.0.2 in Production:
the following error occurs in the alert.log

ERROR
Errors in file /u01/oracle/admin/MFACTOR/bdump/mfactor1_psp0_954436.trc:
ORA-27300: OS system dependent operation:fork failed with status: 11

BUSINESS IMPACT
The issue has the following business impact:
Due to this issue, users cannot connect to the database.


Verified the issue in the log file as noted below:

LOG FILE
Filename = alert_MFACTOR1.log
See the following error:

Process startup failed, error stack:

Mon Sep 18 18:10:35 2006
Process P073 died, see its trace file

Cause
The issue is caused by the following setup: maximum number of processes allowed per user.

The error messages indicating that oracle has problem in forking more process.

Checked the "maxuproc", it is only set to 128.



Please remove the metalink content after Swan & Mash read, Thank you..

OK, now, I will show to you about max_uproc:
$ su
Password:
# echo maxuprc/D | adb -k
physmem 1fd745
maxuprc:
maxuprc:        29995
# sysdef | grep v_maxup
   29995        maximum processes per user id (v.v_maxup)
# echo maxusers/D | adb -k
physmem 1fd745
maxusers:
maxusers:       2048


In Solaris:

max_nprocs = (10 + 16 * maxusers)
maxuprc = (max_nprocs - 5)


Where:

* max_nprocs = Total number of system wide processes

* maxuprc = Total number of processes a non-root user can have occupying a process table slot at any point in time

Quote:

maxusers is a tunable parameter at the kernel level that is by default set to the lesser of the amount of memory in Mbytes or 2048. Range: 1 to 2048, based on physical memory if not set in the /etc/system file; and 1 to 4096, if set in the /etc/system file.



Therefore, I've got:
logvnp@VNP> select (10+(16*2048)-5) max_uprc from dual;

  MAX_UPRC
----------
     32773

logvnp@VNP>


There is one big problem in here:
maxuprc_os is only 29995 but really is 32773.

May you suggest me for something?

Thank you very much!

You may need to increase your JOB_QUEUE_PROCESSES

@gentlebabu: Thank you for your reply!

It's not simple to do with only increasing job_queue_process initialization parameter. I know about my database, and I am sure how many jobs are running concurrently. In my database, there're 4 jobs was submitted by DBMS_JOBS, 5 jobs submitted by DBMS_SCHEDULER, and job_queue_procees=14.

So that, according to OS max_uprocs & max_users, there are
: 29995 max processes, 2048 max users. In Solaris, how many users are default? There is about 18 users, I'm sorry if it's not exactly, but ~18-22, except oracle users. In one server, how many program for each users? Usually, no much, except oracle's application. Trying to execute "vmstat", "prstat", "sar -u x x", "swap -l" to get the list of memory%, cpu%, vm%, swap% for all users's programming whose are concurrently connect to.

What's about oracle processes? OK, using "ps -ef | grep oracle" and pmap -id in which, id is the PID of oracle's process. I often use those commands to calculate what's size of each process, may be DBWr0, J000, ARC0...

And in oracle database, what's the memory size of each process? Oh, in Dedicated Server, PGA & UGA are not separate components, my database was configured to be dedicated server. Select statement's result come from v$statname, v$sesstat, v$session, v$process will show memory. According to v$pgastat, v$sgastat I can tell you that "The problem is in here". Why can I tell that? Because of statspack. The coding of application had got problem, big one! hmm, what's the problem? Tracing bdump, udump, and ash_report, I found that 2 big problems.

One is INSERT statement: 2972118 buffer_get for only 16 executions.
One is one job scheduled by DBMS_SCHEDULER, in which, scan one very big table ~ 120gb, to execute DML Interval=1 mins.

May be they're really problems, may be the really one is other, by anyway, I said that "Thank you". Because you tell me about jobs.

In note 579365.1, Oracle suggests the DBA to increase max_uprocs & max_nprocs, and you see the post below, in my server, max_upros=29995, and for the 11, ORA-27300: OS system dependent operation:fork failed with status: 11, metalink site has one note: https://metalink2.oracle.com/metalink/plsql/f?p=130:14:2428737725030416143::::p14_database_id,p14_docid,p14_show_header,p14_show_help ,p14_black_frame,p14_font:NOT,392006.1,1,0,1,helvetica

I'll feed back to you when I find the really problem, of course, if the problem are not belonged to our coding. Very Happy

Thank you!

Hello,

Yes; Your correct; You may need to increase the processes value; How your going to increase? What's your calculation...

Thank you for your reply, gentlebabu!
I am going to increase pga (pga_aggregate_target) from 2gb to 2.5gb.

I'm sorry because I removed some thing, it's not the referent table to calculate pga

You see 0000000380000000 10485784K rwxsR [ ism shmid=0x24 ]

Take total=10610264 - 10485784 =

logvnp@VNP> select (10610264 - 10485784)/1024 Mb from dual;

        MB
----------
  121,5625


121MB, the process take it from physical memory. Try to capture each other to calculate.

May you correct me if i'm wrong?
Thank you very much!
