Backup a DB2 database and restore redirect it to a different location

[[email protected] ~]$ db2 backup db erpdb to /home/db2inst1/backups

[[email protected]primarynode-1 ~]$ scp ERPDB.0.db2inst1.NODE0000.CATN0000.20170511104723.001 172.16.0.77:/home/db2inst1/backups/

重定向：

[[email protected]oracle backups]$ db2 restore db erpdb from /home/db2inst1/backups/ into devdb77 redirect generate script new_db.txt

修改重定向文件：

[[email protected] backups]$ vi new_db.txt

[[email protected] backups]$db2 list application for db devdb77

[[email protected] backups]$db2 force application (5497) 或者

[[email protected] backups]$db2 force application all

重定向恢复：[[email protected] backups]$db2 -tvf  new_db.txt

最后回滚日志：

[[email protected] backups]$ db2 rollforward db devdb77 to end of logs and complete

表空间满的情况：修改表空间大小

SET TABLESPACE CONTAINERS FOR 5 USING ( FILE ‘/db/db2inst1/data/devdb77/TBS_GAME01_4K‘ 3932160 )

SQL0968C The file system is full. SQLSTATE=57011

[[email protected] backups]$ db2 "ALTER TABLESPACE TBS_GAME01_4K RESIZE (ALL 2392160)"

DB20000I The SQL command completed successfully.

原始大小为3392160 修改为2392160
