Restoring Microsoft Sql Server 7 Master Databases - HP BB118BV - StorageWorks Data Protector Express Package User Manual

•
3. Restart the SQL Server service using the SQL Server Enterprise Manager.
Step 8. Restore the msdb database
Refer to Restoring SQL Server User Databases earlier in this appendix for specific information on
restoring SQL Server databases.
When restoring the msdb database, keep the following considerations in mind:
The msdb database supports SQL Executive and provides a storage area for scheduling information.
•
The schedules that you implement using SQL Enterprise Manager are maintained in the msdb
database. This includes such things as the tasks that you schedule from the Task Scheduling window,
the automatic backups you schedule from the Database Backup/Restore window and all replication
tasks, which are automatically created by the system if the server is configured as a replication
distributor.
During installation of a server, the setup program automatically creates two devices (of 2MB and
•
1MB) on the same disk drive as the master database and then places the msdb database on the 2MB
device (MSDBDATA) and its transaction log on the 1MB device (MSDBLOG). Scheduling
information is then stored in this database.
During a rebuild of the master database, the setup program drops and re-creates the msdb database,
•
which results in a loss of all scheduling information.

Restoring Microsoft SQL Server 7 master databases

A damaged master database is evident by the failure of the SQL Server to start, by segmentation faults or
input/output errors or by a report from DBCC. An example of an error might be damage caused by media
failure in the area in which master database is stored.
The procedure used to recover a damaged master database is different from the procedure used to recover
user databases. If the master database becomes unusable, it must be restored from a previous dump. All
changes made to the master database after the last dump are lost when the dump is reloaded and therefore
must be reapplied.
It is strongly recommended that the master database be backed up each time it is changed. This is best
accomplished by prohibiting the creation of user-defined objects in the master database and by being
aware of the statements and system procedures, and the equivalent actions in SQL Enterprise Manager,
that modify it.
