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/TANTEST ASMCMD> 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 list Database log mode Archive Mode Automatic archival Enabled Archive destination +FRI/tantest/arch1 Oldest online log sequence 14 Next log sequence to archive 15 Current log sequence 15 SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination +FRI/tantest/arch2 Oldest online log sequence 6 Next log sequence to archive 7 Current log sequence 7 SQL>
