oracle11g rac修改归档

oracle11g归档日志可以放在本地、共享存储或ASM磁盘，本次修改放在本地盘中

1、创建归档所需要的路径

节点1：

mkdir /arch1

chown -R oracle:oinstall /arch1

chmod -R 777 /arch1

节点2：

mkdir /arch2

chown -R oracle:oinstall /arch2

chmod -R 777 /arch2

2、备份spfile

任意节点执行create pfile='/u01/app/oracle/initdljyzs1.ora' from spfile; 来备份spfile

3、修改归档日志存放地

alter system set log_archive_dest_1='location=/arch1' scope=both sid='inst1';

alter system set log_archive_dest_1='location=/arch2' scope=both sid='inst2';

4、修改归档模式

1. The following steps need to be taken to enable archive logging in a RAC database environment:

-- shutdown immediate all database instances
$ srvctl stop database -d <db_unique_name>

-- startup database in mount mode
$ srvctl start database -d <db_unique_name> -o mount

-- enable archive logging
$ sqlplus / as sysdba
sql> alter database archivelog;
sql> exit;

-- stop database
$ srvctl stop database -d <db_unique_name>

-- restart all database instances
$ srvctl start database -d <db_unique_name>

-- verify archiving is enabled/disabled by means of:
sql> archive log list;

alter system archive log current;或alter system switch logfile;

至于这两种切换日志的区别我博客有提到。
