Crash enqueue server process

Description – crash enqueue server process using kill.

Run node – primary node where ASCS is running.

Run steps

hahost01:~ # ps -ef | grep enq ha1adm 15453 15441 0 13:35 ? 00:00:01 enq.sapHA1_ASCS00 pf=/usr/sap/HA1/SYS/profile/HA1_ASCS00_ascshost root 17487 8801 0 13:44 pts/1 00:00:00 grep --color=auto enq hahost01:~ # kill -9 15453

Expected result – because the Start_Program_01 = local $(_ENQ) pf=$(_PF) parameter is in the ASCS instance profile, the cluster will failover ASCS (message server process and enqueue process) to the secondary node.
