今天启动ASM报错了,ORA-29701: unable to connect to Cluster Manager

在用DBCA过程中,同样遇到这个问题.
 
搜索了metalink 459775.1
 
Symptoms
When multiple oracle homes exist on a server, the startup of ASM instance fails with error:

ORA-29701: unable to connect to Cluster Manager

Cause
The cluster service is linked to one oracle home and the startup of the ASM instance to another oracle home and thus failing with ORA-29701
Solution
1. Stop CSS process currently running

$ Kill -9

2. With the root user authentication switch to oracle_home/bin directory

#cd $ORACLE_HOME/bin
#localconfig reset $ORACLE_HOME

3. Start the CSS process

# /etc/init.d/init.cssd start

4. Start the ASM instance

由于所在的环境有两个ORACLE_HOME，localconfig reset $ORACLE_HOME 解决自己的问题。

另外可能的情况：
ORA-29701: unable to connect to Cluster Manager

因为安装完10g以后，就直接把/etc/inittab中的h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1这句注释了
取消注释
重新启动

Cause
Connect to CM failed or timed out.

Action
Verify that the CM was started. If the CM was not started, start it and then
retry the database startup. If the CM died or is not responding, check the 
Oracle and CM trace files for errors.

 参考资料,如果出现上面的错误,就检查文件/etc/inittab,看看是否有下面的行:

 h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1

 如果没有上面的行,请添加上;如果注释掉,请取消注释
