今早上班发现在删除过期备份的控制文件镜像时报错，查询mos发现如下文章可以解决，特此记录： Error ORA-19606 on RMAN Delete (文档 ID 1215493.1)，
处理思路是将指定过期的镜像控制文件从控制文件记录的备份信息uncatalog出去，如下
SYMPTOMS：
=== ODM Issue Clarification ===
Receiving error on 'delete obsolete':
delete noprompt obsolete device type disk;
RMAN retention policy will be applied to the command
RMAN retention policy is set to recovery window of 5 days
Deleting the following obsolete backups and copies:
Type Key Completion Time Filename/Handle
-------------------- ------ ------------------ --------------------
Control File Copy 3 01-SEP-10 C:\APP\ADMINISTRATOR\PRODUCT\11.2.0\DBHOME_1\DATABASE\SNCFAXMPRD.ORA
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of delete command on ORA_MAINT_DISK_1 channel at 09/09/2010 02:04:24
ORA-19606: Cannot copy or restore to snapshot control file
CAUSE：
=== ODM Cause Determination ===
The snapshot controlfile is cataloged as a controlfile copy and is now obsolete. RMAN cannot delete this file as it is used by rman.
=== ODM Cause Justification ===
Error and information supplied justifies cause
SOLUTION： === ODM Solution / Action Plan === The snapshot controlfile must be removed as a valid controlfile copy. To do this, you would: RMAN> change controlfilecopy 'C:\APP\ADMINISTRATOR\PRODUCT\11.2.0\DBHOME_1\DATABASE\SNCFAXMPRD.ORA' uncatalog; Confirm with: RMAN> list copy of controlfile;
