DataGuard部署及主从切换

主库：vsgpdb 备库：dgdb 1、确认主库处于归档模式 SQLgt; archive log list Database log mode Archive Mode Au

主库：vsgpdb
 备库：dgdb
 

1、确认主库处于归档模式
 SQL> archive log list
 Database log mode              Archive Mode
 Automatic archival            Enabled
 Archive destination            /gp/arch
 Oldest online log sequence    1307
 Next log sequence to archive  1312
 Current log sequence          1312
 

2、将primary 数据库置为FORCE LOGGING 模式。通过下列语句：
 SQL> select force_logging from v$database;
 

FOR
 ---
 YES
 

SQL> alter database force logging;
 

3.配置Primary数据库的初始化参数
 修改客户端初始化参数文件，增加下列内容
 *.DB_UNIQUE_NAME=vsgpdb
 *.LOG_ARCHIVE_CONFIG='DG_CONFIG=(vsgpdb,dgdb)'
 *.LOG_ARCHIVE_DEST_2='SERVICE=dgdb LGWR SYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=dgdb'
 *.LOG_ARCHIVE_DEST_STATE_2=DEFER
 

 

SQL> alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(vsgpdb,dgdb)';
 SQL> alter system set LOG_ARCHIVE_DEST_2='SERVICE=dgdb LGWR SYNC AFFIRM
  VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=dgdb';
 SQL> alter system set LOG_ARCHIVE_DEST_STATE_2=DEFER;
 

#--------配置standby 角色的参数用于角色转换
 *.FAL_SERVER=DGDB
 *.FAL_CLIENT=VSGPDB
 *.DB_FILE_NAME_CONVERT='/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb'
 *.LOG_FILE_NAME_CONVERT='/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb'
 *.STANDBY_FILE_MANAGEMENT=AUTO
 

SQL> alter system set FAL_SERVER=DGDB;
 

System altered.
 

SQL> alter system set FAL_CLIENT=VSGPDB;
 

System altered.
 

SQL> alter system set DB_FILE_NAME_CONVERT='/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb';
 alter system set DB_FILE_NAME_CONVERT='/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb'
                  *
 ERROR at line 1:
 ORA-02096: specified initialization parameter is not modifiable with this
 option
 

 

SQL> alter system set DB_FILE_NAME_CONVERT='/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb','/gp/oradata', '/opt/dgdb/oradata/dgdb' scope=spfile;
 

System altered.
 

SQL>
 SQL> alter system set LOG_FILE_NAME_CONVERT='/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb' scope=spfile;
 SQL> alter system set STANDBY_FILE_MANAGEMENT=AUTO;
 修改完之后重启
 

4.创建控制文件--primary 库操作
 SQL> alter database create standby controlfile as '/opt/ora10g/oradata/vsgpdb/dgdb03.ctl';
 

SQL> create pfile from spfile;
 

File created.
 

shutdown immediate  --一定要关掉主库再传送数据文件
 

5.传送文件到备库
 初始化参数文件+控制文件+数据文件
 备：192.168.165.26是备库IP
 scp /opt/ora10g/product/10.2.0/db_1/dbs/initvsgpdb.ora dgdb@192.168.165.26:/opt/dgdb/product/10.2.0/db_1/dbs/initdgdb.ora
 scp /opt/ora10g/oradata/vsgpdb/dgdb03.ctl dgdb@192.168.165.26:/opt/dgdb/oradata/dgdb/dgdb01.ctl
 scp /opt/ora10g/oradata/vsgpdb/dgdb03.ctl dgdb@192.168.165.26:/opt/dgdb/oradata/dgdb/dgdb02.ctl

 scp /opt/ora10g/oradata/vsgpdb/sysaux01.dbf dgdb@192.168.165.26:/opt/dgdb/oradata/dgdb/
 scp /opt/ora10g/oradata/vsgpdb/temp01.dbf dgdb@192.168.165.26:/opt/dgdb/oradata/dgdb/
 scp /gp/oradata/temp01.dbf dgdb@192.168.165.26:/opt/dgdb/oradata/dgdb/
 scp /gp/oradata/users01.dbf dgdb@192.168.165.26:/opt/dgdb/oradata/dgdb/
