Yes, it’ll give quite a bit of information, and unless the answer to this next question is yes, irrelevant.
Have you done any work management performance tuning? Such as are the HTTP servers running in *BASE and/or anything else other than the OS running there? Are the applications that manage the HTTP jobs running in *BASE? Is the number of jobs under the HTTP server high enough to handle the highest load?
Has anyone looked at the SQL index advisor to see if there are constant index actions taking place that could be helped if you built the indexes?
I understand the vendor’s request, but I highly doubt that would help. I understand you have reviewed the performance graphs, but they won’t show much if everything is consistent (bad or good) .

Subject: HMC Command - Dynamic Platform Organizer (DPO)
We have a vendor application that runs on our Power 10 that can be accessed via ACS "green screen" telnet session or a local browser. The browser-based version is not accessible outside of the company network. There is an instance that run under QHTTPSVR and a correlating application that runs under its own sub-system to manage sessions and data.
We are experiencing intermittent performance issues with the browser-based version. The ACS session version does not experience any issues. We have reviewed performance graphs and time-of-day related data and see no repeatable issue.
The vendor has requested we execute a command on the HMC - address Dynamic Platform Organizer - DPO.
The command is:
optmem -m managed-system -o start -t affinity [-p partition-names | --id partition-IDs]
[-x partition-names | --xid partition-IDs]
If there are issues, we can stop the process with
optmem -m managed-system -o stop [--optid ID]
I am not familiar with this command. Has anyone used this command and is there any concerns with its execution?
