These address spaces look like stored procedure address spaces and they are
likely marked as a server . Their goals would be managed under the DDF

It is recommended to run the SYSVIEW started tasks in the WLM service class
SYSSTC. Since SYSVIEW is a monitoring product, it is important for the STCs to
have the high priority associated with this class in times of problem
determination.

Put monitors in SYSSTC.
This gives them the second highest DP in the system. You cannot completely

Thank you all for your response and advise. My only reservation is that
SYSVIEW, at times, tends to be heavy-footed and causes the system to
'pause'. This is only because of the data we capture at periodic intervals.
Anyway, that's for me to investigate further and fix.
Thanks, again,
