FIX: The replication on the server does not work any longer when you manually fail over databases in SQL Server 2005 (912471)


The information in this article applies to:

  • Microsoft SQL Server 2005 Standard Edition
  • Microsoft SQL Server 2005 Enterprise Edition
  • Microsoft SQL Server 2005 Developer Edition
BUG #: 415917 (SQLBUDT)
Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.

SUMMARY

This article describes the following about this hotfix release:
  • The issues that are fixed by the hotfix package
  • The prerequisites for installing the hotfix package
  • Whether you must restart the computer after you install the hotfix package
  • Whether the hotfix package is replaced by any other hotfix package
  • Whether you must make any registry changes
  • The files that are contained in the hotfix package

SYMPTOMS

Consider the following scenario. In Microsoft SQL Server 2005, you set up database mirroring for more than one database to run in high-availability mode. You also configure the databases as publishers for transactional replication. You set up a replication to replicate data between the principal server and the mirror server. In this scenario, when you restart the principal server and manually fail over the databases, the replication on the server does not work any longer.

CAUSE

This problem occurs because the sys.databases catalog view is updated incorrectly after you fail over the database that is mirrored. The replication is disabled because the is_published column of the sys.databases catalog view is set back to 0.

Steps to reproduce the problem

  1. Set up three instances of SQL Server 2005 on the following three computers:
    • The principal server
    • The mirror server
    • The witness server
  2. Set up database mirroring for two user databases on the servers in high-availability mode.

    For more information about high-availability mode, see the "Synchronous Database Mirroring (High-Availability and High-Protection Modes)" topic in SQL Server 2005 Books Online.
  3. Set up a replication on the two databases between the principal server and the mirror server.
  4. Restart the principal server to fail over the databases in the next step.
  5. Manually fail over the principal server to the mirror server.

    For more information about how to manually fail over the principal server, see the "Transact-SQL Settings and Database Mirroring Operating Modes" topic in SQL Server 2005 Books Online.
When you complete these steps, the replication on the server does not work any longer.
