关闭
1.先关数据库:
[oracle@oeltan1 ~]$ srvctl stop database -d tantest
2.再关闭crs服务
root@oeltan1 ~]# crsctl stop crs
启动:
[root@oeltan1 ~]# crsctl start crs
[oracle@oeltan1 ~]$srvctl start asm -n node_name
上述开机一般已经启动
[oracle@oeltan1 ~]$ srvctl start database -d tantest
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
1
2
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:
1
2
3
ASMCMD> pwd
+FRI/TANTEST
ASMCMD> mkdir ARCH2
2.修改归档参数
任意一个实例,oracle用户下:
1
2
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:
1
2
3
4
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:
