instance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 string
db_file_name_convert string
db_name string oracle
db_unique_name string oracle
global_names boolean FALSE
instance_name string oracle1
lock_name_space string
log_file_name_convert string
processor_group_name string
service_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
[grid@node4 ~]$ srvctl status database -d oracle
Instance oracle2 is running on node node3
Instance oracle1 is running on node node4
[grid@node4 ~]$ srvctl stop database -d oracle
[grid@node4 ~]$ crs_stat -t
