我是rac模式开启,显示失败,只要把另一个节点关了就好了,不知道以后会不会出问题
问题描述
SQL> shutdown immediate ORA-01109: database not openDatabase dismounted. ORACLE instance shut down. SQL> startup nomount; ORACLE instance started. Total System Global Area 2505338880 bytes Fixed Size 2255832 bytes Variable Size 738198568 bytes Database Buffers 1761607680 bytes Redo Buffers 3276800 bytes SQL> alter database archivelog; alter database archivelog*ERROR at line 1:ORA-01507: database not mounted SQL> alter database mount 2 ;Database altered.

当前为RAC集群模式,更改归档到ASM磁盘组,但是启动归档模式 的时候启动不起来.
问题定位
SQL> show parameter cluster_database NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ cluster_database boolean TRUE cluster_database_instances integer 2 SQL> show parameter name NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ cell_offloadgroup_name stringdb_file_name_convert string db_name string oracle db_unique_name string oracle global_names boolean FALSE instance_name string oracle1 lock_name_space stringlog_file_name_convert string processor_group_name stringservice_names string oracle
因为这个是RAC数据库,他对比单机数据库区别就是: cluster_database参数,这个参数为true的话就是RAC数据库,
cluster_database_instances --->这个就是两个数据库链接到了这个RAC数据库上.
然而,归档日志的话必须为单节点实例才能开启归档模式
所以需要把集群改为单节点实例
即 cluster_database改为false
问题解决
关闭集群
