CRS打补丁时因为种种意外失败,会导致无法启动CRS:
[root@wydb01:5 ~]$ crsctl start crs CRS-6706: Oracle Clusterware Release patch level ('1645742981') does not match Software patch level ('441346801'). Oracle Clusterware cannot be started. CRS-4000: Command Start failed, or completed with errors.
原因是打补丁失败导致本地补丁包不一致,清理本地patch即可启动crs及db,如下操作:
clscfg -localpatch
然后就可以正常启动crs
因此为了避免网络中断等意外原因导致操作失败,打补丁时应该采用后台运行的方式!
