PSP0 (ospid: 20847): terminating the instance due to error 472
System state dump requested by (instance=1, osid=20847 (PSP0)), summary=[abnormal instance termination].
System State dumped to trace file /u01/app/oracle/diag/rdbms/emr/emr/trace/emr_diag_20870_20240131161126.trc
Instance terminated by PSP0, pid = 20847
分析:
这个错误和官方的一个BUG比较接近:Bug 9903826 - ORA-7445 [kcbsacc] and PMON crashing with ORA-7445 [kcbsslc] Causing Instance to Terminate (Doc ID 9903826.8)
解决办法:
alter system set DB_CACHE_ADVICE = OFF;
