生产环境，Oracle Linux 6.4 RAC 11.2.4.0，今天出现了grid集群因为OCR磁盘组不能访问而不能通过命令来显示集群状态信息，在手动mount OCR磁盘组后，准备重启节点2时出现了ORA-01105,ORA-01606错误，具体信息如下:
SQL> startup ORACLE instance started. Total System Global Area 5.3447E+10 bytes Fixed Size 2265864 bytes Variable Size 1.3019E+10 bytes Database Buffers 4.0265E+10 bytes Redo Buffers 160698368 bytes ORA-01105: mount is incompatible with mounts by other instances ORA-01606: parameter not identical to that of another mounted instance
查看错误详细说明，根据错误描述可知是由于2号实例与1号实例由于某些参数设置一样所导致的
[oracle@db2 dbs]$ oerr ora 1105 01105, 00000, "mount is incompatible with mounts by other instances" // *Cause: An attempt to mount the database discovered that another instance // mounted a database by the same name, but the mount is not // compatible. Additional errors are reported explaining why. // *Action: See accompanying errors. [oracle@db2 dbs]$ oerr ora 1606 01606, 00000, "parameter not identical to that of another mounted instance" // *Cause: A parameter was different on two instances. // *Action: Modify the initialization parameter and restart.
使用spfile文件来创建文本格式的pfile文件

从文本参数文件看不出来有什么参数是两个实例不一致的。 通过执行下面的语句来查看2号实例与gc相关的参数

64 rows selected.通过对比发现_gc_read_mostly_locking参数在1号实例中为true，2号实例为false
将所有实例中的_gc_read_mostly_locking参数设置为true
SQL> alter system set "_gc_read_mostly_locking"=true scope=spfile sid='*'; System altered.
重启2号实例成功
SQL> shutdown immediate ORA-01507: database not mounted ORACLE instance shut down. SQL> startup ORACLE instance started.

原因是因为之前有人修改过_gc_read_mostly_locking隐藏参数，只是只修改了1号实例。
