Crash message server process

Description – crash message server using kill.

Run node – primary node where ASCS is running.

Run steps

root@hahost01 ~]# ps -ef | grep ms
ha1adm    182227  182215  0 16:19 ?        00:00:00 ms.sapHA1_ASCS00 pf=/usr/sap/HA1/SYS/profile/HA1_ASCS00_ascshost
root      182994  178689  0 16:22 pts/0    00:00:00 grep --color=auto ms
[root@hahost01 ~]# kill -9 182227

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.

[root@hahost01 ~]# ps -ef | grep ms
ha1adm    183041  182215  0 16:22 ?        00:00:00 ms.sapHA1_ASCS00 pf=/usr/sap/HA1/SYS/profile/HA1_ASCS00_ascshost
root      183425  178689  0 16:24 pts/0    00:00:00 grep --color=auto ms

Recovery procedure – N/A.
