When running the “topas” command on AIX , 3 CCI processes are consuming 100% of CPU in total.
Process names are:
- ccirmtd with 48.7 %
- caiccid with 25.5 %
- ccijimd with 24.5 %
By running the ‘rmtcntrl status’ command, we found that CCI remote process (ccirmtd.exe) tried to initiate a connection to itself on “localhost”
Localhost INACT RETRY
An easy workaround is to add such "localhost" entry in the ccirmtd.prf file:
LOCAL = aixserver1 aixserver1 32768 startup
REMOTE = localhost localhost 32768 nostart retry=0
Then you have to recycle CCI with:
"unisrvcntr stop CA-CCS"
ensure there is no remaining cci process running, otherwise kill them
"unisrvcntr start CA-CCS"
After subsequent startup, the “rmtcntrl status” command is going to display this new line:
Localhost INACT NORETRY
This above line means there won't be any CCI retry to reconnect this "localhost" and the CPU usage will be normal and stable
Note: if you stop CA-CCS components, and the machine is also running Autosys, you'll have to bounce Autosys to re-establish the communication between Autosys and CA-CCS components
