V class hang

[Bryan D. Quinn]

Thanks Steve, actually the operator tried to login from the console window on the test station also. This also hung. So, telnet and rlogin were not the only methods tried.

It's a head scratcher. One of the previous times before I tried to save the dump but it was a partial dump and HP said it was in-conclusive.

Hi,

Though there are 28G of ram, however how much swap space do your system have?

HPUX's process will allocate it's share of swap space before it can start, no matter it will use it or not.

Anyone please correct me if I get it wrong.

Regards,
Thomas

We have the same amount of swap space as physical memory, 28GB.

Bryan,

Why can't you just start check the performance from OS

There are many tools to debug your problem.

1. Sar (Generally runs every 10 Mins) - if you have setup

2. IOSTAT and VMSTAT

3. TOP/Glance

To get more information what is wrong with system

do dmesg and syslog.

Check for any ems messages.

Finally check you space for all vg00 file systems

Ensure that SAP (batch jobs)will not run from cron, they have their backup tool (sm35/36) to do its system admin, so check with SAP BASIS team.
