Hello Biswajit,
thank you for the info.
Could you please take a look at "RZ21 --> Topology --> Context Overview --> Display Overview", if the "Transactional RFC and Queued RFC" context is available and on which instance it is located? You need to check the selfmonitoring structure in RZ20 of this instance for any open alerts or errors. Please check it under:
RZ20 --> SAP CCMS Technical Expert Monitors
--> CCMS Selfmonitoring
--> <SID> --> MoniInfra_<instance>
In this structure please check, if you have enough space on this instance:
Expand "Space" and then double click on "FreeAlertSlots". Are there enough free slots available?
Then please check:
Tooldispatching (short running tasks)
--> Alerts for "Messages"
Do you see here alerts for the method CCMS_tRFC_Collector?
Then please check, if all is OK with the autoabap dispatcher. Please take a look at the structure:
Sapmssy8
Is the runtime less than 5 Min? Display details for the MTE "Sapmssy8_Messages". Do you see here regularly the entries "SAPMSSY8 started" and "SAPMSSY8 completed"?
Please check the MTE:
DataSupplier --> Alerts and details for the MTE "Log" for the methd CCMS_tRFC_Collector
If you cannot find any problems here, then please reset the monitoring segment of the affected instance in "WARMUP" status in RZ21, wait 10 minutes and check the selfmonitoring structure of the instance again, if any errors are reported for CCMS_tRFC_Collector. Please check also startup tools under "RZ20 --> SAP CCMS Technical Expert Monitors --> CCMS Selfmonitoring --> CCMS_Selfmonitoring --> Startuptools once per system", if any problems are reported here for the affected method during "WARMUP" of the CCMS shared memory segment.
Regards,
Alwina
