rac dataguard搭建过程

这几天要为rac大家dataguard，但是实际上rac现在只有但节点运行，因为另一个节点服务器坏了需要维修。


如果某天节点1修好了，在起数据库之前务必先修改tnsname.ora，添加HNDG的部分。不然归档会缺失


sid都叫HNDB
备库监听名叫HNDG好了
db_unique_name 主库叫HNDB，备库叫HNDG






在备库tnsnames.ora添加


HNDB =
  (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hn-db1-vip)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = hn-db2-vip)(PORT = 1521))
      (LOAD_BALANCE = yes)
      (CONNECT_DATA =
        (SERVER = DEDICATED)
        (SERVICE_NAME = HNDB)
      )
  )


HNDG =
  (DESCRIPTION =
     (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = hn-dg)(PORT = 1521))
     )
     (CONNECT_DATA =
        (SERVICE_NAME = HNDB)
     )
  )
  
HNDB2 =
  (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hn-db2-vip)(PORT = 1521))
      (CONNECT_DATA =    
        (SERVER = DEDICATED)        
        (SERVICE_NAME = HNDB)              
        (INSTANCE_NAME = HNDB2)                    
      )
  )
  
HNDB1 =
  (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hn-db1-vip)(PORT = 1521))
      (CONNECT_DATA =    
        (SERVER = DEDICATED)        
        (SERVICE_NAME = HNDB)              
        (INSTANCE_NAME = HNDB1)                    
      )
  )














在主库tnsnames.ora添加
HNDG =
  (DESCRIPTION =
     (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = hn-dg)(PORT = 1521))
     )
     (CONNECT_DATA =
        (SERVICE_NAME = HNDB)
     )
  )

起来的时候
出现这个
ORA-03113: end-of-file on communication channel


alert显示
LGWR: Error 12541 verifying archivelog destination LOG_ARCHIVE_DEST_2
 
Error 12541 received logging on to the standby
Check whether the listener is up and running.


然后自己就直接shutdown了。。。。。。。。


没办法改成这个试试


alter system set log_archive_dest_2='SERVICE=HNDG lgwr SYNC valid_for=(online_logfile,primary_role) db_unique_name=HNDG' scope=spfile;
这个居然可以正常开机了。。


又改回async，这次没自动关机了，alert后台不断报12541而已
alter system set log_archive_dest_2='SERVICE=HNDG lgwr async valid_for=(online_logfile,primary_role) db_unique_name=HNDG' scope=both;


把spfile弄成pfile再拷过去备库




ps:可以用SELECT force_logging from v$database看看是不是强制写日志






















在备库添加standby log
如果要回切需要在主库也加




ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 11('+VGDATA/hndb/onlinelog/slog11a.ora','+VGRECOVERY/hndb/onlinelog/slog11b.ora') SIZE 100m;

在主库上部署备份脚本










#bk.rcv
connect target sys/abc@HNDB2
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
set limit channel c1 kbytes 1800000;
set limit channel c2 kbytes 1800000;
backup full

format '/orabackup/backup/rman2/dataguard%n_%s_%p_%T'
database include current controlfile for standby;
sql 'alter system archive log current';
release channel c1;
release channel c2;
}










备库

漏了删*.remote_listener='LISTENERS_HNDB'




startup nomount 
ok了






清空原数据文件


建好目录




$ mkdir datafile
$ mkdir tempfile
$ mkdir VGDATA
$ mkdir VGRECOVERY
$ 
$ ll
total 0
drwxrwxrwx   2 oracle     oinstall        96 Dec 19 15:02 VGDATA

drwxrwxrwx   2 oracle     oinstall        96 Dec 19 15:02 tempfile
$ pwd
/oracle/app/oradata/HNDB








在备库的/etc/hosts添加










在这个目录下部署恢复脚本
/var/backup/script




run
{
allocate channel chan1 type disk;
allocate channel chan2 type disk;
allocate auxiliary channel aux1 type disk;
allocate auxiliary channel aux2 type disk;
duplicate target database for standby nofilenamecheck;
}




保证和主库的备份目录一致，做一个软连接
cd /orabackup/backup




ln -s /var/backup/rman /orabackup/backup/rman2


nohup rman target  sys/hndb123@HNDB2 auxiliary / @recover.rcv log recover.log &




看来要等很久，归档空间应该毫无压力。
修改备份脚本


主要去掉 delete input
添加
delete noprompt archivelog until time "to_date(to_char(sysdate-2,'yyyy-mm-dd hh24:mi:ss'),'yyyy-mm-dd








connect target sys/abc@HNDB
run{
allocate channel c1 type disk connect sys/hndb123@HNDB2;
allocate channel c2 type disk connect sys/hndb123@HNDB2;
sql 'alter system archive log current';
backup tag 'full-archive-bk'
       filesperset 3
       format '/orabackup/backup/arch_bak1/arch%n_%s_%p_%T'
archivelog all;
delete noprompt archivelog until time "to_date(to_char(sysdate-2,'yyyy-mm-dd hh24:mi:ss'),'yyyy-mm-dd
 hh24:mi:ss')";


release channel c1;
release channel c2;
}




shutdown immediate;  
startup nomount;
alter database  mount standby database;
alter database recover managed standby database disconnect from session;




不断出现
PING[ARC1]: Heartbeat failed to connect to standby 'HNDG'. Error is 16191


忘记替换密码文件




果然是这问题


看看正常不
select sequence#,applied,ARCHIVAL_THREAD# from v$archived_log order by sequence#;




把源库的脚本解注释


明天回来再搞备库的删归档脚本






百思不得其解。。。为毛主库建了standby_log之后，rman恢复备库没有standby_log?
印象中单机dg会有啊，难道是我记忆错乱还是双机不一样？


尝试一下在备库建吧。。修改一下路径


alter database recover managed standby database cancel;
