oracle 11g rac进程起停

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

[oracle@host1 ~]$ crs_start  -all
CRS-0184: Cannot communicate with the CRS daemon.

[oracle@host1 ~]$ 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

[root@host1 ~]# /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

[root@host1 ~]# /oracle/product/crs/bin/crsctl enable crs
[root@host1 ~]# /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
