Oracle研究中心案例分析：运维DBA反映在对Oracle数据库进行恢复时报错，执行recover database报RMAN-06004 RMAN-20003错误。

最近遇到11.2.0.3 RAC FOR AIX平台在出账高峰期生成的归档日志有损坏，导致归档日志文件备份失败。

关键在此系统上有DG，并且在出账的期间，由于需要，将备库转换成SNAPSHOT STANDBY，此时遇到主库已经成功传输到备库的归档文件在主库不能删除的BUG，还由于其它一些原因，禁用主机传输到备库的归档路径。悲剧来了，归档日志文件坏了，没有办法，月初高峰期后，使用增量备份来前滚物理备库吧，但是不巧的是又遇到下面的报错。

released channel: t1

released channel: t2

released channel: t3

released channel: t4

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of recover command at 05/05/2016 16:29:47

RMAN-06004: ORACLE error from recovery catalog database: RMAN-20003: target database incarnation not found in recovery catalog

下面是整个操作过程

1，主库进行增量备份

提供命令给备份工程师，让备份工程师完成增量备份

SELECT MIN(checkpoint_change#) FROM V$DATAFILE;

BACKUP INCREMENTAL FROM SCN xxxxx DATABASE FOR 'STANDBY_20160000'；

大概几个小时后，增量备份完成。

2，主库备份控制文件

主库备份控制文件，并传输到备库主机

backup current  controlfile  for standby format='/tmp/con_standby.ctl';

scp con_standby.ctl 192.168.111.12:/tmp

3，备库还原控制文件

QL> !rman target /

Recovery Manager: Release 11.2.0.3.0 - Production on Thu May 5 16:14:46 2016

Copyright (c) 1982, 2011, Oracle and/or its affiliates.  All rights reserved.

connected to target database: ACCT (not mounted)

RMAN> restore controlfile from '/tmp/con_standby.ctl';这里应该使用restore standby controlfile

RMAN> alter database mount;

database mounted

released channel: ORA_DISK_1

4，更改数据文件路径

由于主库与备库的数据文件路径不一样，需要手动修改

RMAN> catalog start with '/linshi/dev';

修改数据文件的路径

RMAN> switch database to copy;

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of switch to copy command at 05/05/2016 16:17:32

RMAN-06571: datafile 1 does not have recoverable copy

这里数据文件1有报错，感觉不好，正常情况这里应该。下面使用手动的方式来实现

SQL> select 'set newname for datafile '||file#||' to '||chr(39)||name||chr(39)||';' from v$backup_copy_details order by file#;

'SETNEWNAMEFORDATAFILE'||FILE#||'TO'||CHR(39)||NAME||CHR(39)||';'

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

set newname for datafile 1 to '/linshi/dev/vx/rdsk/htz/lv_system_111.dbf';

set newname for datafile 2 to '/linshi/dev/vx/rdsk/htz/lv_sysaux_111.dbf';

set newname for datafile 3 to '/linshi/dev/vx/rdsk/htz/lv_undo_111.dbf';

set newname for datafile 4 to '/linshi/dev/vx/rdsk/htz/lv_users_111.dbf';

...............................................................................

5，recover数据库

oracle@htz#[/linshi/shell]nohup sh ./recover_database.sh &

[1]     30671256

oracle@htz#[/linshi/shell]Sending output to /home/oracle/nohup.out

Starting recover at 05-MAY-16

released channel: t1

released channel: t2

released channel: t3

released channel: t4

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of recover command at 05/05/2016 16:29:47

RMAN-06004: ORACLE error from recovery catalog database: RMAN-20003: target database incarnation not found in recovery catalog

6，查看数据库的角色

SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PRIMARY

这里看到数据库主库模式，下面重新还原一次控制文件

SQL> !rman target /

Recovery Manager: Release 11.2.0.3.0 - Production on Fri May 6 00:47:09 2016

Copyright (c) 1982, 2011, Oracle and/or its affiliates.  All rights reserved.

connected to target database: ACCT (not mounted)

RMAN> restore standby controlfile from '/tmp/standby.ctl';

Starting restore at 06-MAY-16

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=2002 device type=DISK

channel ORA_DISK_1: restoring control file

channel ORA_DISK_1: restore complete, elapsed time: 00:00:01

output file name=/linshi/control.ctl

Finished restore at 06-MAY-16

SQL> select database_role from v$database;

DATABASE_ROLE

--------------------------------

PHYSICAL STANDBY

RMAN> list incarnation;

using target database control file instead of recovery catalog

List of Database Incarnations

DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time

------- ------- -------- ---------------- --- ---------- ----------

2       2       ACCT     3716340531       CURRENT 14754146318553 30-APR-16

RMAN> reset database to INCARNATION  1;

database reset to incarnation 1

RMAN> list incarnation;

List of Database Incarnations

DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time

2       2       ACCT     3716340531       ORPHAN  14754146318553 30-APR-16

7，还原数据文件

SQL> alter system set standby_file_management=manual;

System altered.

run

{

ALLOCATE channel t1 type 'sbt_tape';

ALLOCATE channel t2 TYPE 'sbt_tape';

ALLOCATE channel t3 TYPE 'sbt_tape';

ALLOCATE channel t4 TYPE 'sbt_tape';

send 'NSR_ENV=(NSR_SERVER=htzback,NSR_CLIENT=htz01)';

restore datafile 647,645,646 from tag 'FORSTANDBY2319';

}

8，RECOVER数据库

RMAN>  run

2> {

3> allocate channel t1 type 'sbt_tape' PARMS 'ENV=(NSR_SERVER=htzback,NSR_CLIENT=htz02)';

4> allocate channel t2 type 'sbt_tape' PARMS 'ENV=(NSR_SERVER=htzback,NSR_CLIENT=htz02)';

5> allocate channel t3 type 'sbt_tape' PARMS 'ENV=(NSR_SERVER=htzback,NSR_CLIENT=htz01)';

6> allocate channel t4 type 'sbt_tape' PARMS 'ENV=(NSR_SERVER=htzback,NSR_CLIENT=htz01)';

7> recover database;

8> release channel t1;

9>  release channel t2;

10>  release channel t3;

11>  release channel t4;

12>  }

这里没有在报错了

9，添加STANDBY日志文件

SQL>

alter database add standby logfile  thread 1 '/htz/standby11.dbf'  reuse

alter database add standby logfile  thread 1 '/htz/standby12.dbf'  reuse ;

alter database add standby logfile  thread 1 '/htz/standby13.dbf'  reuse ;

alter database add standby logfile  thread 1 '/htz/standby14.dbf'  reuse ;

alter database add standby logfile  thread 1 '/htz/standby15.dbf'  reuse ;

alter database add standby logfile  thread 1 '/htz/standby16.dbf'  reuse ;

alter database add standby logfile  thread 1 '/htz/standby17.dbf'  reuse ;

alter database add standby logfile thread 2 '/htz/standby21.dbf'   reuse ;

alter database add standby logfile thread 2 '/htz/standby22.dbf'   reuse ;

alter database add standby logfile thread 2 '/htz/standby23.dbf'   reuse ;

alter database add standby logfile thread 2 '/htz/standby24.dbf'   reuse ;

alter database add standby logfile thread 2 '/htz/standby25.dbf'   reuse ;

alter database add standby logfile thread 2 '/htz/standby26.dbf'   reuse ;

alter database add standby logfile thread 2 '/htz/standby27.dbf'   reuse ;

10，时时运用模式

SQL> recover managed standby database using current logfile disconnect;

Media recovery complete.

11，启用块跟踪与修改文件管理参数

整个增量前滚DG完成
