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=

LOG_ARCHIVE_DEST_STATE_2=ENABLE
LOG_ARCHIVE_MAX_PROCESSES=10
FAL_SERVER=racdb
FAL_CLIENT=prod
prod1.FAL_CLIENT=prod1

*.STANDBY_ARCHIVE_DEST='/u01/arch1'

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

SYS@ 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

SYS@ prod1 >alter database  backup controlfile  to trace;

SYS@ 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

SYS@ prod1 >alter database  create  standby controlfile as '/home/oracle/std_control02.ctl' ;

Database altered.            创建新的控制文件

SYS@ prod1 > startup force  nomount pfile='/home/oracle/initprod.ora';

SYS@ 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
