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:
