Oracle11g RAC开启关闭、设置归档

Oracle11g RAC开启关闭、设置归档


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

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
