Linking Servers

  • We are rewriting one of our in-house applications, including database modifications.  The current version passes data to another application database residing on the same SQL server using embedded SQL statements. 

    We are creating a new version of our database to allow us to rollout the new application in stages across the company and our new database will reside on a different server but need to write data to the same secondary application database.  I a researching pros and cons of linking the two servers, I have testing in development and it appears to answer all our problems.  Both are SQLServer 2000.  Any input on this subject will be greatly appreciated.

  • linked servers can be a real Godsend.  You should exercise great care in setting up the security between them.  I have seen several cases where the linked server login mapping leaves the target server wide open.  You should also generally avoid joining large tables across the servers.

  • I've been unsuccessful linking servers.  Could you give me any guidance ?

    Thanks
