环境:

现象:alert告警日志报错

Clearing Resource Manager plan via parameter

ORA-00020: No more process state objects available
ORA-20 errors will not be written to the alert log for
the next minute. Please look at trace files to see all
the ORA-20 errors.
Process m000 submission failed with error = 20
Process m000 submission failed with error = 20
原因:
安装数据库后没有调整参数,processes参数使用默认值150,不够用。
处理:
调整参数:
alter system set processes=1000 scope=spfile
顺便调整:
alter system set open_cursors=800 scope=both
结果:
重启后观察不再报该错。
