RMAN备份集不能有效释放空间

Posted 2020-11-09

公司某生产系统，每天凌晨一点做数据库全被。crontab调用rman脚本实现其数据库备份，备份目录是通过NFS挂载到本地，有同事发现该目录有7.5T的空间一直留有5月1号至今的备份集为能释放。登陆主机进行查看；

下面是备份脚本，以及删除脚本
[[email protected] ~]$ more /home/oracle/nfs/rman_level0.sh
#!/bin/bash
source ~/.bash_profile
rman target / nocatalog log /home/oracle/nfs/rman_full.log append << EOF
run
{allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup filesperset 3 as compressed backupset database format ‘/home/oracle/nfs/fulldata%d%T%s%p‘;
sql ‘alter system archive log current‘;
sql ‘alter system archive log current‘;
sql ‘alter system archive log current‘;
sql ‘alter system archive log current‘;
sql ‘alter system archive log current‘;
backup archivelog all format ‘/home/oracle/nfs/arch%d%T%s%p‘ delete input;
backup current controlfile format ‘/home/oracle/nfs/ctl%d%T%s_%p‘;
}
EOF
rman target / nocatalog log /home/oracle/nfs/rman_delete.log append << EOF
allocate channel for maintenance type disk;
crosscheck backupset;
crosscheck archivelog all;
delete noprompt expired backup;
crosscheck copy;
report obsolete;
delete noprompt obsolete;
EOF

脚本两部分，一部分是备份数据库，第二部分是删除过期失效备份集，没有问题；

查看RMAN的保留周期；

自己动手删除一下过期备份看看

RMAN> delete noprompt obsolete;

RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
using channel ORA_DISK_1
Deleting the following obsolete backups and copies:
Type Key Completion Time Filename/Handle

报错了，这个在印象里是个bug，下面是解决方法；
RMAN> show SNAPSHOT CONTROLFILE NAME;

RMAN configuration parameters for database with db_unique_name UASDB are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/u01/app/oracle/product/11.2.0/db_1/dbs/snapcf_uasdb.f‘; # default

RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/u01/app/oracle/product/11.2.0/db_1/dbs/snapcf_uasdb-temp.f‘;

new RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/u01/app/oracle/product/11.2.0/db_1/dbs/snapcf_uasdb-temp.f‘;
new RMAN configuration parameters are successfully stored
