19c数据库PGA设置过高出现告警
19c数据库启动后,发现alert日志里面出现告警:
2021-04-26T09:14:24.671750+08:00
**********************************************************************
PGA_AGGREGATE_TARGET specified is high
Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl1/trace/orcl1_ora_13774.trc (incident=144013):
ORA-00700: soft internal error, arguments: [pga physmem limit], [14574157824], [8228128153], [], [], [], [], [], [], [], [], []
Incident details in: /u01/app/oracle/diag/rdbms/orcl/orcl1/incident/incdir_144013/orcl1_ora_13774_i144013.trc
根据提示,PGA设置过高,如果SGA+PGA>OS Memory * 80%,启动时则会给出错误警告(仅在19c版本中给出错误告警)
处理方法显而易见了,将PGA调小,使得SGA+PGA<OS Memory * 80%即可
