使用RMAN备份在一台机器上恢复已有DB NAME数据库

案例背景，开发人员需要从生产库同步数据到UAT数据库，由于数据量较大，恢复需要的时间较长，而这期间测试人员还要在UAT环境进行测试，不能耽误测试人员的工作，这样就需要在恢复数据库的同时，UAT数据库还要正常对外提供服务，这样，UAT服务器上就需要面临两套DBID和DBNAME同样的数据库，数据库版本11.2.0.4.0。

如果同一台主机上存在两个DBNAME相同的数据库，那么在后启动的数据库在MOUNT的时候会遇到ORA-01102错误。

SQL> alter database mount;
alter database mount
*
ERROR at line 1:
ORA-01102: cannot mount database in EXCLUSIVE mode

告警日志报错信息如下；

ALTER DATABASE   MOUNT
sculkget: failed to lock /opt/oracle/product/11g/dbs/lkIVLDB exclusive
sculkget: lock held by PID: 9257
ORA-09968: unable to lock file
Linux-x86_64 Error: 11: Resource temporarily unavailable
Additional information: 9257
ORA-1102 signalled during: ALTER DATABASE   MOUNT...

这个问题是因为在$ORACLE_HOME/dbs目录下面的lk+DBNAME文件的锁竞争导致的，如果删除这个文件，那么后启动的数据库可以正常启动，之前启动的数据库将不能正常访问。因此，在使用RMAN恢复数据库之前，需要将之前的数据库的DBNAME改掉，如下为使用nid工具修改DBNAME案例：

首先将数据库启动到MOUNT状态。

修改参数文件和密码文件。

[oracle@SL010A-IVO03 ~]$ cd $ORACLE_HOME/dbs
[oracle@SL010A-IVO03 dbs]$ mv orapwIVLDB orapwIVLUAT
SQL> alter system set db_name='IVLUAT' SCOPE=SPFILE;

ORA-01589: must use RESETLOGS or NORESETLOGS option for database open

必须以resetlogs的方式打开数据库。

SQL> alter database open resetlogs;

Database altered.

修改数据库的service_names参数，重新注册监听。

SQL> alter system set service_names=IVLDB;

System altered.
SQL> alter system register;

System altered.

此时，应用程序已经可以访问UAT数据库，可以使用RMAN恢复另一套数据库了。

登录UAT数据库，查看数据文件存放目录，新的数据库数据文件不要和原有数据库的数据文件存放到一起。

SQL> select name from v$datafile;

NAME
---------------------------------------------
/data/u01/IVLDB/system01.dbf
/data/u01/IVLDB/sysaux01.dbf
/data/u01/IVLDB/undotbs01.dbf
/data/u01/IVLDB/users01.dbf
/data/u01/IVLDB/datafile/TB_TS_MC01.DBF
/data/u01/IVLDB/datafile/TB_TS_IV01.DBF

/data/u01/IVLDB/datafile/TB_TS_IV03.DBF
/data/u01/IVLDB/datafile/TB_TS_IV04.DBF
/data/u01/IVLDB/datafile/TB_TS_IV05.DBF
/data/u01/IVLDB/datafile/TB_TS_IV06.DBF

创建参数文件，修改后作为新数据库的参数文件。

SQL> create pfile from spfile;

File created.

修改参数文件，主要修改以下内容。

[oracle@SL010A-ISITDB3 dbs]$ vi initIVLDB.ora
*.memory_target=4294967296    --内存足够可以不用修改
*.control_files='/data/u01/uatdb/control01.ctl','/data/u01/uatdb/control02.ctl'

修改参数文件名字为inituatdb.ora，uatdb是新要恢复的数据库的SID。

[oracle@SL010A-ISITDB3 dbs]$ mv initIVLDB.ora inituatdb.ora

设置ORACLE_SID环境变量为uatdb，连接数据库，将数据库启动到nomount状态。

[oracle@SL010A-ISITDB3 dbs]$ sqlplus / as sysdba

创建数据文件存放目录，这里统一存放在/data/u01/uatdb目录下面。

[oracle@SL010A-ISITDB3 ivldb]$ cd /data/u01/
[oracle@SL010A-ISITDB3 u01]$ mkdir uatdb

将生产库的备份上传到UAT服务器，由于生产库做的是增量备份，所以需要将周日(6月7日的全备)及6月13日的备份拷贝到UAT服务器。传输过程略。

恢复控制文件。

此时，数据库已经MOUNT状态，此时的数据库service_names参数和原有的UAT数据库的service_names参数冲突，修改为uatdb。

安装开发人员需求，尝试基于时间点的不完全恢复。

RMAN> run{
2> allocate channel t1 device type disk;
3> allocate channel t2 device type disk;
4> allocate channel t3 device type disk;
5> allocate channel t4 device type disk;
6> set until time "to_date('2015-06-12 00:00:00','yyyy-mm-dd hh24:mi:ss')";
7> recover database;
8> release channel t1;
9> release channel t2;
10> release channel t3;
11> release channel t4;
12> }

此时，告警日志会抛出一堆的错误，但是不要紧，恢复已经进行，RMAN并不会中断。

这个错误是由于恢复的时候没有 和restore放到一起导致的，因为restore的时候，制定了set newname转换了数据文件，这个错误不用理会，因为马上就会在告警日志看到以下可爱的信息。

恢复完成后，打开数据库遇到ORA-03113错误，这个错误通常是数据文件损坏或不存在导致。

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel

登录数据库查看下resetlog是否成功。

UAT数据库不需要打开归档，关闭归档。

SQL> alter database noarchivelog;

Database altered.

再次尝试打开数据库，遇到ORA-30012错误。

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-30012: undo tablespace 'UNDOTBS1' does not exist or of wrong type
Process ID: 28079
Session ID: 421 Serial number: 3

这个报错信息就很明显了，因为生产库是RAC环境，UAT是单实例环境，而打开这个UAT数据库的参数文件是从单实例的数据库拷贝过来的，当时修改参数的时候并没有更改undo_tablespace参数。

SQL> alter system set undo_tablespace='IVLDB1_UNDO' scope=spfile;

System altered.

SQL> alter database open;

Database altered.

修改undo_tablespace参数后，数据库可以启动，此时，恢复工作并没有完成，还需要增加临时文件。

SQL> select NAME, FILE#,TS#,STATUS from v$tempfile;

/data/u01/uatdb/ivalue_temp1.dbf
/data/u01/uatdb/ivalue_temp2.dbf
/data/u01/uatdb/ivalue_temp3.dbf

至此，恢复完成，UAT数据库可正常提供服务。

总结：如果要在一台服务器上恢复一套DB NAME相同的数据库，而且这两个数据库需要同时对外提供访问，那么需要将一套数据库的DB NAME改掉。
