IBM C2090-541 Exam Syllabus Topics:

IBM DB2 9.7 DBA for Linux UNIX and Windows Sample Questions:

1. A database administrator created a new database from an existing full database backup image. If the original database resided on a 64-bit AIX server and the new database was created on a different 64-bit AIX server, which two statements are correct? (Choose two.)

A) Incremental backup images for the original database can be used to restore the new database.
B) Incremental backups are not allowed until a non-incremental backup is taken.
C) Existing packages will be copied to the new database and can be used immediately.
D) Existing SQL procedures must be dropped and re-created in the new database before they can be used.

2. Due to an application error, some data was deleted from a very large table residing in table space TS1. The table space was then renamed TS2 before the error was detected. Rather than try and rebuild this table, it was decided that database DB1 would be restored and then rolled forward to a point-in-time (PIT) before the delete operation took place. Unfortunately the PiT roll forward was done to a time that was too early and some critical transactions were missing when the database was brought back on-line. Which steps must be taken to ensure that the critical transactions which are currently missing from the database are correctly applied to the database and that table space TS1 is renamed TS2?

A) 1. Restore table space TS1 from the DB1 backup image.
2.Roll forward to the correct point-in-time.
3.Rename table space TS1 to TS2.
4.Re-run the batch processes.
B) 1, Restore database DB1
2. Roll forward to end of logs.
C) 1. Restore table space TS1 from the DB1 backup image.
2. Roll forward to end of logs.
D) 1. Restore database DB1.
2.Roll forward to the correct point-in-time.
3.Rename TS1 to TS2.

3. If a non-recoverable database crashes, how can a DBA successfully restart the database if a table space is damaged and cannot complete crash recovery?

A) The damaged table space will require that the entire database be restored from the latest backup image because the database is non-recoverable and will not be accessible.
B) The damaged table space must be restored from the latest backup and any active transaction logs in the log path can then be applied to it using the TABLESPACE ONLINE option of the ROLLFORWARD DATABASE command. This will bring the table space on-line and synchronize it with the rest of the database.
C) The database must be restarted using the RESTART DATABASE command with the DROP PENDING TABLESPACES option specified. At that point, the database can be brought on-line and the damaged table space must be dropped and re-created.
D) The damaged table space must be restored from the latest backup image. Once restored from the backup image, the RESTART DATABASE command can be issued to apply all the relevant transactions from the active logs. At that point, the database will come on-line and all table spaces will be synchronized.

B) Log file 101 will be successfully created in the primary log path since infinite logging has been enabled. Applications will continue processing normally.
C) The database will appear to be hung since the active log space is full and the BLK_LOG_DSK_FUL parameter is set to YES.
D) Log file 101 will go into the OVERFLOWLOGPATH directory since the active log space is full and infinite logging has been enabled.
