***************************
rac1 修改初始化参数文件
修改 归档日志存放路径
主库端（RAC)修改spfile：
添加以下内容：
db_unique_name 不需要 删掉此项
*.LOG_ARCHIVE_CONFIG=‘DG_CONFIG=(prod,racdb)‘
LOG_ARCHIVE_DEST_1=
‘LOCATION=/u01/arch1
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)

LOG_ARCHIVE_DEST_2=

VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)

LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
LOG_ARCHIVE_MAX_PROCESSES=10
FAL_SERVER=racdb
FAL_CLIENT=prod
prod1.FAL_CLIENT=prod1
prod2.FAL_CLIENT=prod2
*.STANDBY_ARCHIVE_DEST=‘/u01/arch1‘
DB_FILE_NAME_CONVERT=‘/u01/app/oracle/oradata/racdb‘,‘+DG1/prod/datafile‘,‘/u01/app/oracle/oradata/racdb‘,‘+DG1/prod/tempfile‘，‘/u01/app/oracle/oradata/racdb‘，‘+DG2/prod/datafile‘
LOG_FILE_NAME_CONVERT=‘/disk1/oradata/racdb‘,‘+DG1/prod/onlinelog‘,‘/disk2/oradata/racdb‘,‘+RECOVERY/prod/onlinelog‘
STANDBY_FILE_MANAGEMENT=AUTO

rac1 添加standby日志 （比redo日知组多一组）
alter database add standby logfile thread 1 线程1 组 5
(‘+dg1/prod/onlinelog/std_redo01a.log‘ ,‘+recovery/prod/onlinelog/std_redo05.log‘) size 50m;
alter database add standby logfile thread 1 线程1 组 6
(‘+dg1/prod/onlinelog/std_redo02a.log‘ ,‘+recovery/prod/onlinelog/std_redo06.log‘) size 50m;
alter database add standby logfile thread 1 线程1 组 7
(‘+dg1/prod/onlinelog/std_redo03a.log‘ ,‘+recovery/prod/onlinelog/std_redo07.log‘) size 50m;
alter database add standby logfile thread 2 线程2 组 8
(‘+dg1/prod/onlinelog/std_redo04a.log‘ ,‘+recovery/prod/onlinelog/std_redo08.log‘) size 50m;
alter database add standby logfile thread 2 线程2 组 9
(‘+dg1/prod/onlinelog/std_redo04a.log‘ ,‘+recovery/prod/onlinelog/std_redo09.log‘) size 50m;
alter database add standby logfile thread 2 线程2 组 10
(‘+dg1/prod/onlinelog/std_redo04a.log‘ ,‘+recovery/prod/onlinelog/std_redo10.log‘) size 50m;
alter database add standby logfile thread 2 线程2 4组
(‘+dg1‘,‘+recovery‘) size 50m ;
两个节点 故添加 线程1 线程2
查看添加的standby 日志
[email protected] prod1 >select group#,thread#,status from v$standby_log;
GROUP# THREAD# STATUS
---------- ---------- ----------
7 1 UNASSIGNED
8 1 UNASSIGNED
9 1 UNASSIGNED
10 1 UNASSIGNED
11 2 UNASSIGNED
12 2 UNASSIGNED
13 2 UNASSIGNED
14 2 UNASSIGNED
数据库物理结构发生变化 故 重建 standby 控制文件
[email protected] prod1 >alter database backup controlfile to trace;
[email protected] prod1 >create spfile=‘/home/oracle/spfileprod1.ora‘ from pfile;
集群环境下的spfile 只有 一句话而已
***************************
rac 1 启动实例
[email protected] prod1 >alter database create standby controlfile as ‘/home/oracle/std_control02.ctl‘ ;
Database altered. 创建新的控制文件
[email protected] prod1 > startup force nomount pfile=‘/home/oracle/initprod.ora‘;
[email protected] prod1 > create spfile=‘+DG1/PROD/spfile.ora‘ from pfile=‘?/dbs/inittmp.ora‘;
其实创建spfile pfile 不用启动数据库 只要进入sqlplus 环境就可以了 呼呼
