TCPIP$SSH - ID uses more Pgflquo now

Hi All,

We had a issue with SFTP while transferring files between windows to openvms server. It was identified that the TCPIP$SSH was using more page file quota (180,000) than defined (20,000). Is there a way to identify how the page file quota used by the account exceeded suddenly, as it was working well before for same file transfers?

   How, exactly?

   I don't know.  I'd guess that something somewhere changed, which
caused the increased memory usage, but I can't see your files, or what
your "same file transfers" actually do.  And if I could see them, I
might still not know anything useful.

   If you run multiple jobs at the same time, and this quota is shared
among them, then that might do it.

   If you have a support contract, then I'd ask there.  Otherwise, if
it's really necessary, then I'd probably increase Pgflquo for that
account, and wait for more trouble.

Exactly HOW did you determine PGFLQUOTA usage of the processes running under the TCPIP$SSH account ?

PGFLQUOTA is a 'pooled limit' and is shared between all processes running concurrently under the same process job tree. An incoming SFTP connection creates a network process TCPIP$SS_BGnnnn and a subprocess TCPIP$SSH_nn, both running under the TCPIP$SSH account and sharing their PGFLQUOTA. A SHOW PROC/QUOTA/ID=xxx for both processes shows the same value - the remaining PGFLQUOTA for this job tree.

Then there is also the dynamic SYSGEN parameter PQL_MPGFLQUOTA, which determines the minimum amount of PGFLQUOTA for any created process.
