Server performance

Hi Guys,

I am running Oracle database on RHEL 2.6.18-164.el5, now I want to check and make sure that my server is performing optimally.

I check top:
Code:
top - 09:45:03 up 2 days, 15:22,  3 users,  load average: 2.57, 2.85, 2.77
Tasks: 433 total,   3 running, 430 sleeping,   0 stopped,   0 zombie
Cpu(s):  3.0%us,  0.5%sy,  0.0%ni, 93.6%id,  2.7%wa,  0.0%hi,  0.2%si,  0.0%st
Mem:  65997076k total, 58306788k used,  7690288k free,   217256k buffers
Swap: 66557284k total,        0k used, 66557284k free, 45256956k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
23430 weblogic  19   0 18.2g 5.2g 5024 S 101.8  8.3 214:10.85 java

23572 oracle    16   0 5395m 1.5g 1.5g R  7.8  2.3   5:32.58 oracle
 2443 oracle    16   0 5395m 1.5g 1.5g D  3.9  2.3   3:54.75 oracle
 5220 oracle    18   0 5400m  79m  67m S  3.9  0.1   7:45.31 oracle
 2441 oracle    15   0 5393m 1.5g 1.5g S  2.0  2.3   3:30.00 oracle
 7206 oracle    15   0 5404m  73m  71m S  2.0  0.1   2:42.38 oracle
13871 oracle    15   0 5392m  46m  43m S  2.0  0.1   0:01.95 oracle
    1 root      15   0 10348  692  584 S  0.0  0.0   0:04.08 init

How do I tell if my server is running optimally or is there anything that I should take note of from the results of top above?

Thanks in advance...

Please help !!!!

MONITOR(8)						      System Manager's Manual							MONITOR(8)

NAME
monitor - Directory Server script for monitoring database performance SYNOPSIS
monitor [ -Z serverID ] [ -D rootdn ] [ -w password ] [ -b basedn ] [-P protocol] [-h] DESCRIPTION
Retrieves performance monitoring information. To run this script, the server must be running. OPTIONS
A summary of options is included below: -Z Server Identifier The server ID of the Directory Server instance. If there is only one instance on the system, this option can be skipped. -D Root DN The Directory Manager DN, or root DN. If not specified, the script will search the server instance configuration for the value. -w password The rootdn password. -b basedn The DN of a backend from cn=config. -P Protocol The connection protocol to connect to the Directory Server. Protocols are STARTTLS, LDAPS, LDAPI, and LDAP. If this option is skipped, the most secure protocol that is available is used. For LDAPI, AUTOBIND is also available for the root user. -h Display the usage. EXAMPLE
monitor -P STARTTLS Note: security must be enabled to use protocol STARTTLS. If STARTTLS is not available it will default to next strongest/available protocol automatically. monitor -Z instance2 -D 'cn=directory manager' -w password -b 'cn=monitor,cn=userRoot,cn=ldbm database,cn=plugins,cn=config' Note: You only need to bind as the root DN if you want to look at a backend monitor. DIAGNOSTICS
Exit status is zero if no errors occur. Errors result in a non-zero exit status and a diagnostic message being written to standard error. AUTHOR
