关闭
1.先关数据库:
1. 分别创建两个实例的ASM目录
任意一个实例,grid用户下:
SQL> alter diskgroup FRI add directory '+FRI/TANTEST';SQL> alter diskgroup FRI add directory '+FRI/TANTEST/ARCH1';
还可以通过asmcmd创建目录:
ASMCMD> pwd+FRI/TANTESTASMCMD> mkdir ARCH2
2.修改归档参数
任意一个实例,oracle用户下:
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH1' SCOPE=both SID='tantest1'; ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH2' SCOPE=both SID='tantest2';
3.两个节点上分别都执行:
SQL> SHUTDOWN IMMEDIATE;SQL> STARTUP MOUNT;SQL> ALTER DATABASE ARCHIVELOG;SQL> ALTER DATABASE OPEN;
--修改一个实例时,另一个实例不能在open状态,否则报ORA-01126: database must be mounted in this instance and not open in any
4.分别检查:
SQL> archive log listDatabase log mode Archive ModeAutomatic archival EnabledArchive destination +FRI/tantest/arch1Oldest online log sequence 14Next log sequence to archive 15Current log sequence 15SQL> archive log listDatabase log mode Archive ModeAutomatic archival EnabledArchive destination +FRI/tantest/arch2Oldest online log sequence 6Next log sequence to archive 7Current log sequence 7SQL>
