Troubleshooting Solaris platforms

The following procedures describe how to troubleshoot Solaris platform workstation
issues.
Procedure 8-1 Problem: Slow processing on a Solaris workstation and
CPU peaks
The workstation is taking too long to perform a task. Check the CPU status to ensure
that one process is not using most of the CPU cycles. Then use the mpstat and ps
commands to further review CPU usage data.
When CPU usage remains high, and performance suffers, contact your Alcatel-Lucent
support representative. Provide the data collected in this procedure.
You can also perform other procedures:

8-2
• If you are you performing a large listing operation using the 5620 SAM client
GUI or OSS, check the LAN throughput using the netstat command, as described
in Procedure 9-3.
Check for excess disk usage using the vmstat command, as described in
•
Procedure 8-3.
Open a command or shell tool.
Change to the 5620 SAM installation directory by typing:
cd /installation_directory ↵
where installation_directory is the installation directory of the 5620 SAM software
Run the prstat command to check for processes that are consuming CPU cycles:
i To list the top CPU processes using the UNIX utility prstat, type:
prstat ↵
Depending on your system configuration, approximately the top 20 processes
are displayed.
ii Review the output.
The top 5620 SAM process listed under the CPU column should be the Java
process. However, the Java process should not be consuming too much CPU.
Some Oracle processes could also take CPU time, depending on the database
load.
iii Press ESC-Q to quit or CTRL-C to stop the top command.
