Crash message server process

Description – crash message server using kill.

Run node – primary node where ASCS is running.

Run steps

hahost01:~ # ps -ef | grep ms
ha1adm   15452 15441  0 13:35 ?        00:00:00 ms.sapHA1_ASCS00 pf=/usr/sap/HA1/SYS/profile/HA1_ASCS00_ascshost
root     16832  8801  0 13:41 pts/1    00:00:00 grep --color=auto ms
hahost01:~ # kill -9 15452

Expected result – because the Restart_Program_00 = local $(_MS) pf=$(_PF) is in the ASCS instance profile, the message server will restart on the same node and no action is taken by the cluster.

hahost01:~ # ps -ef | grep ms
ha1adm   17013 15441  0 13:42 ?        00:00:00 ms.sapHA1_ASCS00 pf=/usr/sap/HA1/SYS/profile/HA1_ASCS00_ascshost
root     17116  8801  0 13:42 pts/1    00:00:00 grep --color=auto ms

Recovery procedure – N/A.
