Symptoms
After standby switchover, the RMS process terminates the instance due to the following error:
ORA-00600: internal error code, arguments: [kcbz_zib_simulation_1], [53956], [805], [], [], [], [], [], [], [], [], []
You have the following set in your parameter file:
db_lost_write_protect=TYPICAL
memory_target=314572800
From the trace file, it can be seen that there is a SCN Mismatch:
For example, in this case:
========= Dump for incident 221050 (ORA 600 [kcbz_zib_simulation_1]) ========
