  • X RMAN Crosscheck后delete obsolete遇到RMAN-06091的解决

    先摘录一段对CROSSCHECK的描述

    当archivelog或是backup被手工删除后,需要运行crosscheck.该命令确保recovery catalog或是控制文件中记录的数据与硬盘上的文件一致。

    对于找不到的文件,CROSSCHECK会把它的状态标为EXPIRED.然后,你运行DELETE EXPIRED命令就可以把rman repository中的相关记录和硬盘上的文件删除。

    如果有些文件被错误地标为EXPIRED,那么在确认文件存在时,再次运行CROSSCHECK BACKUP可以将这些文件重置为AVAILABLE状态。

    也就是说,对于硬盘上已经不存在的文件,用DELETE EXPIRED在RMAN中删除相关记录。对于已经超过retention policy的备份,用DELETE OBSOLETE从硬盘和磁带设备上删除,并从RMAN中把记录删除。

    在执行完

    Crosscheck backup;

    Crossscheck backuppiece;

    Crosscheck archivelog all;

    Delete obsolete;报RMAN-06091: no channel allocated for maintenance (of an appropriate type)

     

    研究了一下,之前的备份一部分是直接备份在硬盘上,另一部分是通过DP备份在磁带上的。出现这样的错误是因为有磁带上的数据,但是未申请磁带类型的channel造成的。

    RMAN> allocate channel for maintenance type disk;

    allocated channel: ORA_MAINT_DISK_6

    channel ORA_MAINT_DISK_6: sid=137 devtype=DISK

    RMAN> delete expired archivelog all;

    specification does not match any archive log in the recovery catalog

    这个应该是正常的,没有发现expired log.

    RMAN> delete obsolete;

    RMAN retention policy will be applied to the command

    RMAN retention policy is set to redundancy 1

    Deleting the following obsolete backups and copies:

    Type                 Key    Completion Time    Filename/Handle

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

    Backup Set           2499   2011-11-24 11:39:28

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

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

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

    RMAN-03002: failure of delete command at 12/15/2011 17:05:42

    RMAN-06091: no channel allocated for maintenance (of an appropriate type)

    这里出错了

    解决的办法是分别删除硬盘上与磁带上的过期备份数据。

    RMAN>delete obsolete device type disk;

    删除硬盘上的过期备份

    RMAN retention policy will be applied to the command

    RMAN retention policy is set to redundancy 1

    Deleting the following obsolete backups and copies:

    Do you really want to delete the above objects (enter YES or NO)? YES

    deleted backup piece

    backup piece handle=/backup/db_full_31.1 recid=31 stamp=768343384

    deleted control file copy

    control file copy filename=/backup/bj.ctl recid=4 stamp=768343437

    deleted backup piece

    backup piece handle=/backup/db_full_32.1 recid=32 stamp=768343461

    deleted backup piece

    backup piece handle=/u01/oracle/flash_recovery_area/GZ/backupset/2011_12_14/o1_mf_annnn_TAG20111214T144526_7gjkjly0_.bkp recid=38 stamp=769877137

    deleted backup piece

    Deleted 17 objects

    deleted backup piece

    backup piece handle=/backup/sp recid=11 stamp=768061712

    deleted backup piece

    backup piece handle=/backup/arc0dmsld1e recid=13 stamp=768259119

    deleted backup piece

    backup piece handle=/backup/arc0emsld29 recid=14 stamp=768259146

    Deleted 3 objects

    这回成功了

    RMAN>  allocate channel for maintenance device type 'sbt_tape' PARMS 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=gz,OB2BARLIST=swt-oracle-full)';

    这里PARMS后面的参数与备份时RMAN脚本中的参数相同

    allocated channel: ORA_MAINT_SBT_TAPE_7

    channel ORA_MAINT_SBT_TAPE_7: sid=136 devtype=SBT_TAPE

    channel ORA_MAINT_SBT_TAPE_7: Data Protector A.06.11/243

    RMAN> delete obsolete;

    RMAN retention policy will be applied to the command

    RMAN retention policy is set to redundancy 1

    Deleting the following obsolete backups and copies:

    Type                 Key    Completion Time    Filename/Handle

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

    Backup Set           2499   2011-11-24 11:39:28

      Backup Piece       2511   2011-11-24 11:39:28 swt-oracle-full<gz_7:768051562:1>.dbf

    Do you really want to delete the above objects (enter YES or NO)? yes

    deleted backup piece

    backup piece handle=swt-oracle-full<gz_7:768051562:1>.dbf recid=1 stamp=768051562

    Deleted 26 objects

    这样就成功了
