checking max_async usage - I have glance

[John Jimenez]

We received an Oracle error that might have to do with the kernal MAX_ASYNC I found another thread where someone asked how to check how much is being used. Someone said you could use glance. But I have not seen this specific kernal measurement in there. Does anyone know where exactly in glance it is? Or another command to measure utilization? thanks.

Try the sysdef command.

sysdef shows the value, but not how much is actually being utilized. Plus MAX_ASYNC is not one listed.

[Geoff Wild]

How about kcusage?

What version of OS are you running?

Thank you Geoff, but kcusage does not monitor MAX_ASYNC either.

[John Jimenez]

HPUX 11.23. The command did show one issue on both servers.

Hi John,

Actually Enhancement request has been raise for monitorinng MAX_ASYNC_PORT to be included into measureware metrics, but no news.

if you are familiar with P4 kernel debugging tools, there is p4_async_print will give you what you need. You may request from HP Support

Thank you. I have never heard of P4 kernel debugging tools. I will check on that. Yes HP got back with me and told me that I am out of luck that glance or anything else will not measure this.
