- SQL Server parallelism optimization
  The performance of an SQL Server database instance can often be improved by small tweaks. Performance might also be hindered by simple oversights. In fact, some SQL Server parallelism settings have suboptimal default values. Moreover, they have to be re-tuned after an hardware upgrade. Other issues might arise from inadvertent hardware configurations, especially when SQL Server is hosted on a virtual machine (VM).

Uninstalling a Linux replication server

To uninstall a replication server, call the database-stored procedure delete_replication_server, which removes the specified ID from the replication set.

Ensure you specify the identifier of the server to delete.

If you are using the DB2 database, log in and run the following procedure:

call dbo.delete_replication_server(n)

where n is the identifier of the server to delete.

If you are using the Microsoft SQL Server database, log in and run the following procedure:

exec BFEnterprise.dbo.delete_replication_server n

where n is the identifier of the server to delete.
