环境Linux 5.8 10.2.0.5 RAC,两个节点只能一个节点mount,如果尝试mount另外节点就报ORA-01105和ORA-01606错误
数据库版本
复制代码 代码如下:

SQL> select * from v$version;

节点1 mount报错
复制代码 代码如下:

SQL> startup
ORACLE instance started.

Total System Global Area  171966464 bytes
Fixed Size                  2094832 bytes

ORA-01105: mount is incompatible with mounts by other instances
ORA-01606: gc_files_to_locks not identical to that of another mounted instance
Error:    ORA 1105 
Text:     mount is incompatible with mounts by other instances 
-------------------------------------------------------------------------------
Cause:  An attempt was made to mount the database, but another instance has already mounted 
        a database by the same name, and the mounts are not compatible.
        dditional messages will accompany this message to report why the mounts are incompatible.
Action:  See the accompanying messages for the appropriate action to take.

Error:  ORA 1606 
Text:   GC_FILES_TO_LOCKS not identical to that of another mounted instance 
-------------------------------------------------------------------------------
Cause:  The initialization parameter GC_FILES_TO_LOCKS is not the same as 
        another instance mounted in parallel mode.
        This parameter must be the same as that for all shared instances.
Action: Modify the parameter to be compatible with the other instances, then
        shut down and restart the instance.
 

根据这个错误提示,查询两个节点的gc_files_to_locks参数,均为空值(默认值),也就是值相同
复制代码 代码如下:

SQL> show parameter gc_files_to_locks;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
gc_files_to_locks                    string
 

检查两个节点的gc相关隐含参数,发现所有值也均一致

_gc_undo_affinity_locks        if TRUE, get affinity locks for undo                                  TRUE   
_gc_use_cr                     if TRUE, allow CR pins on PI and WRITING buffers                      TRUE   
_gc_vector_read                if TRUE, vector read current buffers                                  TRUE
 

仔细对比数据库参数,发现undo异常
复制代码 代码如下:

--节点1
SQL>  show parameter undo

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
undo_management                      string      MANUAL
undo_retention                       integer     900
undo_tablespace                      string      SYSTEM

 
--节点2
SQL>  show parameter undo

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
undo_management                      string      AUTO
undo_retention                       integer     900
undo_tablespace                      string      UNDOTBS1
 

这里已经明确,因为两个节点的undo_*相关参数配置不正确,导致数据库只能一个节点mount。进一步定位问题发现,原来是因为dba粗心在编辑节点1的参数文件的时候把undo_*相关的参数给弄丢了,从而数据库使用了默认值undo_management=manual,undo_tablespace=system
