从Java代码还原DB2数据库

Question

I need to backup and resotre DB2 database from Java code. I can make backup by executing

CALL SYSPROC.ADMIN_CMD('BACKUP DATABASE MY_DB ONLINE TO "/tmp" EXCLUDE LOGS WITHOUT PROMPTING')

On the other hand, I have some linux db2 client commands to restore

db2 connect to MY_DB; 
db2 quiesce db immediate force connections; 
db2 connect reset;
db2 'RESTORE DATABASE MY_DB ONLINE FROM "/tmp" TAKEN AT 20151223185416 WITHOUT PROMPTING';
db2 ROLLFORWARD DATABASE MY_DB TO END OF LOGS ONLINE;

Can I somehow turn it into the stored procedure and call it from java code?

Thanks

It's not possible to perform a database-level recovery operations ( RESTORE or ROLLFORWARD ) while the database is online. Thus, you can't be connected to the database and do this. You can, however, perform tablespace-level recovery operations; you can restore any tablespace (other than SYSCATSPACE ) and perform the rollforward operation.

Keep in mind if you are doing this, you could run into minimum-point-in-time recovery issues – the database catalog can't disagree with the state of a tablespace.

Be aware, though, that the ADMIN_CMD procedure is not compatible with RESTORE , so you won't be able to do this via a JDBC connection to your database.
