CPU Utilization in K 210 Server

We have one HP 800 series K-210 server with:

Harddisk ( int + Ext ) : 122 GB
Memory: 1 GB
OS: HP-UX 10.20
Database : Oracle 8.0.6
No. of users : 200

Problem Description: The CPU utilization in the machine is always 100 % and it takes more time for processing.We are running only oracle application.

Please give us a solution.

Thanks in advance.

Regards,
Surbal.

Re: CPU Utilization in K 210 Server

Hi,
The cpu utilization of 100% on a loaded box could be normal...
What makes you think you are in trouble?
what is the output of top?
what does swapinfo give you?
Are there any zombies?
...

Re: CPU Utilization in K 210 Server

hi,
ALWAYS at 100% might be an indication that your cpu is the bottleneck.
However 1GB RAM for 200 users on Oracle8 might not enough, so your server might be swapping like hell, which also consumes cpu (and disk activity).
Always check the three major sources together : cpu, memory & disk I/O. An overload on one will always cause an increased load on the other.

All unix flavours are exactly the same . . . . . . . . . . for end users anyway.

Re: CPU Utilization in K 210 Server

Hi
100% CPU utilisation can be due to kernel configuration also
What are the values of
DBC_MAX_PCT
NPROC
MAXFILE
MAXLIES_LIM
SHMMAX
..
Check it using command sysdef or kmtune -l
And in oracle
check the values of
db_blcok_size
log_buffer
shared_pool_size
... Check in the init*.ora

...BPK...
