    If you don't get to connect on database, you will have to restore it.

    The basic restore command for restoring a full database from a disk backup image is

    db2 RESTORE DATABASE dbname FROM directory TAKEN AT timestamp

    To restore from TSM use:

    db2 RESTORE DATABASE dbname USE TSM TAKEN AT timestamp

    The timestamp represents the time the database

    was backed up (it's the timestamp you see when the backup completes and

    it also exists in the recovery history file and for backups to disk you

    can see it in the filename or path)

    Assuming the backup was done online with log archiving enabled, there is one more thing to do. When you perform an online backup, the restore must apply any transactions that were going on when the backup occurred in order to make sure the database is consistent. So now you must roll forward the database or the tablespaces to a point of consistency. For database level restores, you can roll forward to any point between the end of the backup and the current time (i.e. end of logs).

    To check if a backup image is corrupted, you can use the db2ckbkp command

    db2ckbkp -h <backup_image>

    To check the backups taken on your server you can perform the following command

    db2 list history backup all for <dbname>

    Output:

    Op Obj Timestamp+Sequence Type Dev Earliest Log Current Log Backup ID

    -- --- ------------------ ---- --- ------------ ------------ --------------

    B D 20080328013138001 N D S0000002.LOG S0000002.LOG

    Contains 4 tablespace(s):

    00001 SYSCATSPACE

    00002 USERSPACE1

    00003 SYSTOOLSPACE

    00004 DMS_TS

    Comment: DB2 BACKUP SAMPLE ONLINE

    Start Time: 20080328013138

    End Time: 20080328013213

    Status: A

    EID: 8 Location: c:\SAMPLE.0\DB2\NODE0000\CATN0000\20080328

    The Start Time: 20080328013138 is the backup image timestamp.

    To roll the database forward to the end of the logs and open the database for access

    db2 ROLLFORWARD DATABASE dbname TO END OF LOGS AND STOP

    To rollforward to a given point in time you can say

    db2 ROLLFORWARD DATABASE dbname TO isotime USING LOCAL TIME AND STOP

    If you able to connect on database, but some tablespaces are offline or are in the not normal state, you need to check and fix the problem.

    Soon, a document will be post here with more details step by step to teach what you have to do when a database get crashed
