ORA-01618: redo thread 2 is not enabled - cannot mount 错误

今天用两台linux Red Hat 4 搭建RAC(10G)的时候出现此错误,,后来解决了,给分享一下。

我刚刚建立好RAC,能打开节点1,打开节点2时报此错,查看节点1的日志如下:

SQL> select * from v$Log; // 只有节点1的日志,却没有节点2的日志

GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- ---------
1 1 2 52428800 2 NO INACTIVE 473022 02-APR-12
2 1 3 52428800 2 NO CURRENT 500037 02-APR-12

在节点1上给节点2建立日志组

SQL> alter database add logfile thread 2
2 ('+dg1','+recovery') size 10m;

Database altered.

再建立一组日志,好和节点1一样都有两组日志

SQL> alter database add logfile thread 2
2 ('+dg1','+recovery') size 10m;

Database altered.

添加完后我又在节点二打开数据库,却还是报此错误,又在节点1执行了下面的操作才OK的

SQL> alter database enable thread 2;

Database altered.
