CA IDMS Tuesday Tip by Edward Gorga, Principal Support Engineer for June 4, 2013.
There is also a screen that will let you select the remote system to monitor from a list of actively running CVs (PF19 - Active System Summary).
This feature uses cross memory communication services provided by a new address space, the IDMSINFO service provider which has to be started as a separate started task, one per LPAR.
Two comments on PERFMON so far.
The Performance-Monitor Sysgen Module delivered with R18.5 is actually the R18.0 one. If you have done a Base Install, you will have to include the PERFORMANCE-MONITOR-DYN-185U module manually to get all the 18.5 definitions.
If you have ASG VDB installed on any CV, the VDB Access module ACCNAME will appear instead of the Startup module name in the new System screen. Seems to work though.
I wasn't quite accurate. It seems to be just Program definition PMMSGSRT which is missing from module PERFORMANCE-MONITOR. It is in the PERFRMANCE-MONITOR -DYN member.
You can get the problem by trying to cancel a Task on an External system from the new PERFMON. Then you get the Unable to Load PMMSGSRT message.
This is now resolved with PTF RO60033- "PERFMON PROGRAM FOR 18.5 NOT DEFINED IN INSTALL". It provides an updated DLODPERF member.
Once you are inside Perfmon you can change the system with the command[b] SYStem <sys name> .
