Recovering from failures

Performance problems

Performance problems are generally perceived as:

• Sluggish response at the operating system prompt

• Slow program execution

• Some users/programs unable to get a response

Use the following procedure to troubleshoot a performance problem:

Step 1. At the console window of the SSP, use one or both of the following

commands to check for active processes making heavy use of system

resources:

• ps

• top

See Managing Systems and Workgroups and the ps and top man pages

for more information about options and usage.

Step 2. Enter a

Ctrl-C from the terminal exhibiting the problem to abort an

executing command.

Step 3. Check another terminal to verify that the problem is not just a console

hang.

Step 4. Contact the Hewlett-Packard Customer Response Center.

HP-UX kernel configuration can affect performance. Refer to

“Configuring HP-UX for V-Class Servers” on page 120. For more detailed

information refer to HP-UX 11.0 Configurable Kernel Parameters and HP

V-Class Server HP-UX Configuration Notes available at the following
