错误现象：
[oracle@node1 ~]$ srvctl add database -d stddb -o /u01/app/oracle/product/11.2.0/db_1/ -n cuug
[oracle@node1 ~]$ srvctl add instance -d stddb -i stddb1 -n node1
[oracle@node1 ~]$ srvctl add instance -d stddb -i stddb2 -n node2
[oracle@node1 ~]$ srvctl config database -d stddb

[oracle@node1 ~]$ srvctl start database -d stddb
[oracle@node1 admin]$ sqlplus '/as sysdba'

通过sqlplus连接Instance：
[oracle@node1 admin]$ sqlplus sys/oracle@stddb as sysdba

尽然连接的是idle的instance
解决方法：
[oracle@node1 ~]$ srvctl add database -d stddb -o $ORACLE_HOME -n cuug
将Oracle软件包的主目录换成变量！
[oracle@node1 ~]$ srvctl add instance -d stddb -i stddb1 -n node1
[oracle@node1 ~]$ srvctl add instance -d stddb -i stddb2 -n node2
[oracle@node1 ~]$ srvctl start database -d stddb
[oracle@node1 ~]$ sqlplus '/as sysdba'
