Not Equal Result for Process Entry Slots (MAXPROCESSCNT) after Autogen

rickysetia — Wed, 20 Mar 2013 12:10:38 GMT

Hi,

I have problem with my OpenVMS 4-node cluster.

Due to an issue, I increase Process Entry Slots from 200 to 400.

Changing in SYS$COMMON:[SYSEXE]MODPARAMS.COMMON :

Change :

MAX_MAXPROCESSCNT = 200

To :

MIN_MAXPROCESSCNT = 400

Then : @SYS$UPDATE:AUTOGEN GETDATA REBOOT FEEDBACK

In node 1-3 :

show mem/full

Slot Usage (slots): Total Free Resident Swapped

Process Entry Slots 400 318 82 0

Balance Set Slots 398 318 80 0

However in node 4 :

Slot Usage (slots): Total Free Resident Swapped

Process Entry Slots 1015 932 83 0

Balance Set Slots 1013 932 81 0

Can advice me why in node 4 the the Process Entry Slots become 1015, not 400 as in other nodes ?

Is this normal condition ?

Thanks a lot.

Check SYS$SYSTEM:AGEN$PARAMS.REPORT for node 4. There may be a reason for AUTOGEN incrementing that parameter. Or check any node-specific parameter files for node 4.

Hi Volker,

Thanks for your help.

I wasn't aware of the AGEN$PARAMS.REPORT file.

One difference of this node 4 AGEN$PARAMS.REPORT compared to the others :

There are lines :

This run of AUTOGEN is *NOT* based on FEEDBACK information.
The resulting calculations may not be representative of your workload.
Hewlett-Packard recommends the use of feedback to
adjust system resources to match system workloads.

I am sure I used : @SYS$UPDATE:AUTOGEN GETDATA REBOOT FEEDBACK

I attach the params.report.

Maybe there is another command to force the node to read the MODPARAMS.COMMON ?

Thanks.

Hi,

you used GETDATA REBOOT FEEDBACK, but maybe there was no feedback data available ? Consider using SAVPARAMS as first parameter to make sure, that feedback data get collected.
