SQL Server 2000 permits the creation of links to OLE DB data sources called linked servers. After linking to an OLE DB data source, it is possible to reference rowsets from the OLE DB data sources as tables in Transact-SQL statements and to pass commands to the OLE DB data sources and include the resulting rowsets as tables in Transact-SQL statements. Each distributed query can reference multiple linked servers and can perform either update or read operations against each individual linked server. A single distributed query can perform read operations against some linked servers and update operations against other linked servers. The Microsoft OLE DB Provider for Oracle allows distributed queries to query data in Oracle databases.
Transact-SQL scripts can be used to create defined operators or alerts. Scripting all the
predefined operators and alerts and copying them to the servers if the same group of operators is responsible for responding to the same alerts on other servers can save time.
The scenario states that power interruptions have occurred in the past. By buying a battery backup solution for the disk controllers the power interruption problem would be prevented.
The DBCC SHRINKDATABSE cannot be executed until the previous job step, the differential backup, has been completed. We should increase the time between these two job steps, or even better configure the last job step to run only after the differential backup has been completed.
Note: The DBCC SHRINKDATABASE statement shrinks data files on a per-file basis but shrinks log files as if all the log files existed in one contiguous log pool. The target size for the data and log files cannot be smaller than the minimum size of a file that was specified when the file was originally created, or the last explicit size set with a file size changing operation such as the ALTER DATABASE statement with the MODIFY FILE option or the DBCC SHRINKFILE statement.
