Oracle11g RAC开启关闭、设置归档小结
关闭
1.先关数据库：
2.再关闭crs服务
[
启动：
[oracle@oeltan1 ~]$srvctl start asm -n node_name
上述开机一般已经启动
归档设置：
1. 分别创建两个实例的ASM目录
任意一个实例，grid用户下：
[grid@oeltan1 ~]$ sqlplus “/as sysasm”
SQL> select name from V$asm_diskgroup;
NAME
——————————————————————————–
CRS
DATA1
FRI
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>
