关闭
1.先关数据库：
[oracle@oeltan1 ~]$ srvctl stop database -d tantest
</div>2.再关闭crs服务
[
root@oeltan1 ~]# crsctl stop crs
</div>
启动：
[root@oeltan1 ~]# crsctl start crs
[oracle@oeltan1 ~]$srvctl start asm -n node_name
</div>
上述开机一般已经启动
[oracle@oeltan1 ~]$ srvctl start database -d tantest
</div>归档设置：
1. 分别创建两个实例的ASM目录
任意一个实例，grid用户下：
# su - grid
[grid@oeltan1 ~]$ sqlplus "/as sysasm"
SQL> select name from V$asm_diskgroup;
NAME
--------------------------------------------------------------------------------
CRS
DATA1
FRI
</div>
SQL> alter diskgroup FRI add directory '+FRI/TANTEST'; SQL> alter diskgroup FRI add directory '+FRI/TANTEST/ARCH1';</div>
还可以通过asmcmd创建目录：
ASMCMD> pwd +FRI/TANTEST ASMCMD> mkdir ARCH2</div>
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';</div>
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;</div>
--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></div> </div>
