对于unknown的进程要crs_stop -f 加进程名
再start
crs启动失败 crs_start -all CRS-0184: Cannot communicate with the CRS daemon.
因为crs_start属于应用层的指令，启动crs的时候会失败
[[email protected] ~]$ crs_start -all
CRS-0184: Cannot communicate with the CRS daemon.
[[email protected] ~]$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
ps -ef |grep init
crs有个启动的高可能进程 开机它在自动起 CRS
有时候开机启不起来 可以先杀了这个进程试下
/etc/init.d/init.ohasd
所以要在集群层启动crs
使用root用户权限执行crsctl
或者 /etc/init.d/init.crs
或者 /u01/app/11.2.0/grid/bin/crsctl start crs
[[email protected] ~]# /oracle/product/crs/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
然后设置开机自启动
[[email protected] ~]# /oracle/product/crs/bin/crsctl enable crs
[[email protected] ~]# /oracle/product/crs/bin/crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
再在oracle 用户下使用crs_stat -t
