ORA-00245: control file backup operation failed

1、现象：

使用rman备份RAC的控制文件不成功。

查看rman的配置如下：

RMAN> show all;

RMAN configuration parameters for database with db_unique_name PROD9 are:

CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

CONFIGURE BACKUP OPTIMIZATION OFF; # default

CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/export/home/ora11/%F';

CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default

CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE MAXSETSIZE TO UNLIMITED; # default

CONFIGURE ENCRYPTION FOR DATABASE OFF; # default

CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default

CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/PROD/product/11.2.0/dbs/snapcf_PROD91.f'; # default

备份的时候报错如下：

RMAN> run {

2> allocate channel d3 type disk;

3> backup format '/export/home/ora11/cntrl_%d_%p_%c_%s' current controlfile;

4> }

allocated channel: d3

channel d3: SID=2458 instance=PROD91 device type=DISK

Starting backup at 23-JUL-12

channel d3: starting full datafile backup set

channel d3: specifying datafile(s) in backup set

released channel: d3

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

RMAN-03009: failure of backup command on d3 channel at 07/23/2012 11:22:33

ORA-00245: control file backup operation failed

2、解决：

重新配置控制文件快照的存放位置，下面show的最后一句：

RMAN> show all;

RMAN configuration parameters for database with db_unique_name PROD9 are:

CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

CONFIGURE BACKUP OPTIMIZATION OFF; # default

CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/export/home/ora11/%F';

CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default

CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE MAXSETSIZE TO UNLIMITED; # default

CONFIGURE ENCRYPTION FOR DATABASE OFF; # default

CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default

CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+SYS/PROD9/snapcf_PROD91.f';

请看上面这个最后一句，rac环境中，控制文件的快照必须备份到能够被所有节点的数据实例访问到的地方，也就是必须放在共享的位置。

配置完之后，再进行控制文件的备份，成功。

RMAN> run {

2> allocate channel d3 type disk;

3> backup format '/export/home/ora11/cntrl_%d_%p_%c_%s' current controlfile;

4> }

allocated channel: d3

channel d3: SID=2458 instance=PROD91 device type=DISK
