Oracle 11G RAC开启和关闭归档日志
Oracle 11G RAC开启和关闭归档日志
一、RAC开启归档日志
1.创建归档日志存放目录
[grid@coredb1 ~]$ asmcmd
ASMCMD> cd /
ASMCMD> ls
DATA/
FLASH/
ASMCMD> cd FLASH
ASMCMD> mkdir coredb
ASMCMD> cd coredb
ASMCMD> mkdir arch
ASMCMD> cd arch
ASMCMD> pwd
+FLASH/coredb/arch
2.检测各节点是否开启归档，并设置归档路径
[oracle@coredb1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.1.0 Production on Fri Jan 29 13:05:24 2016
Copyright (c) 1982, 2009, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Data Mining and Real Application Testing options
SQL> archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination /u01/app/oracle/product/11.2.0/db_1/dbs/arch
Oldest online log sequence 23
Current log sequence 24
SQL> alter system set log_archive_dest_1='location=+FLASH/coredb/arch' scope=spfile sid='*';
System altered.
3.关闭集群数据库
[grid@coredb1 ~]$ srvctl stop database -d coredb
[grid@coredb1 ~]$ crs_stat -t
Name Type Target State Host

4.开启归档日志（只需在一个节点进行以下操作）
将一个节点启动到mount状态,在该节点进行以下操作
[grid@coredb1 ~]$ srvctl start instance -d coredb -i coredb1 -o mount
[root@coredb1 ~]# su - oracle
[oracle@coredb1 ~]$ sqlplus / as sysdba

SQL> alter database archivelog;
Database altered.

Database altered.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +FLASH/coredb/arch
Oldest online log sequence 23
Next log sequence to archive 24

5.启动其他节点数据库（目前只有节点2）
[grid@coredb1 ~]$ srvctl start instance -d coredb -i coredb2
二、关闭归档日志
1.关闭数据库集群
[grid@coredb1 ~]$ srvctl stop database -d coredb
2.将一个节点启动到mount状态,在该节点进行以下操作
[grid@coredb1 ~]$ srvctl start instance -d coredb -i coredb1 -o mount
[root@coredb1 ~]# su - oracle
[oracle@coredb1 ~]$ sqlplus / as sysdba

3.启动其他节点数据库（
