oracle RAC－－归档日志的开启方法

oracle RAC－－归档日志的开启方法

 

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

 

10g R1  要修改cluster_database参数  ，10G R2和以后的版本就不需要了
 
1. 例子(10g R1或之前)： 
srvctl stop database -d RAC
节点1
sql>startup mount
SQL> alter system set log_archive_dest_1='location=/racdb1_arch' scope=spfile sid='RAC1';
SQL> alter system set log_archive_dest_1='location=/racdb2_arch' scope=spfile sid='RAC2';
SQL> alter system set log_archive_dest_2='service=rac2' scope=spfile sid='RAC1';
SQL> alter system set log_archive_dest_2='service=rac1' scope=spfile sid='RAC2';
SQL> alter system set  standby_archive_dest='/racdb2_arch' scope=spfile sid='RAC1';
SQL> alter system set  standby_archive_dest='/racdb1_arch' scope=spfile sid='RAC2';
sql>alter system set cluster_database=false scope=spfile;
sql>shutdown immediate
sql>startup mount
sql>alter database archivelog
sql>alter database open
sql>alter system set cluster_database=true scope=spfile;
sql>shutdown immediate
srvctl start database -d RAC

2. 例子(10g R2或之后)：  
节点1
SQL>startup mount;
SQL> alter system set log_archive_dest_1='location=/racdb1_arch' scope=spfile sid='RAC1';
SQL> alter system set log_archive_dest_1='location=/racdb2_arch' scope=spfile sid='RAC2';
SQL> alter system set log_archive_dest_2='service=rac2' scope=spfile sid='RAC1';
SQL> alter system set log_archive_dest_2='service=rac1' scope=spfile sid='RAC2';
SQL> alter system set  standby_archive_dest='/racdb2_arch' scope=spfile sid='RAC1';
SQL> alter system set  standby_archive_dest='/racdb1_arch' scope=spfile sid='RAC2';
srvctl stop database -d RAC

节点1
SQL> startup mount
SQL> alter database archivelog;

srvctl start database -d RAC

 

3. 测试归档日志的切换：

 

 

节点一，二上分别执行切换日志操作如下：

SQL> alter system switch logfile; 操作执行这条语句5次

 

节点一查询：

SQL> !ls -l /racdb*
/racdb1_arch:
