New Features

  • Added support for the following SQL Server SP versions: 2014 SP1, 2012 SP2 and SP3, 2008R2 SP3, 2008 SP4.
  • This version of SQL Server Plug-in v201.5.10 excludes Windows Internal Database instance on Windows Server 2008/2012 from any protection level.

 

Changed Features

  • This plug-in supersedes the previous released Neverfail for SQL Server Plug-in v201.5.9

 

Issues Fixed

  • Replication filters may be removed if a database is detected or declared offline (EN-507).

 

Known Issues

  • SQL Server monitoring rules do not use the very same DB connection string as the one specified in the SqlServerConnections.xml (EN-672).
  • Applies to SQL Server 2014  using In-Memory Optimized Tables: After a switchover is performed the user might see a warning message in the user-interface or logs stating that a certain Instance/Database is in a recovery state and the "Database Online Status" rule is unable to mark that instance/database as being ONLINE; Example " Rule Triggered: The following databases are not online: Instance/Database RECOVERING. File filters will be removed for these databases. They will be restored when the databases come back online: OFFLINE DBs detected"  (Ref-EN-329).
    Explanation/Workaround: This is just a temporary/misreported state, which doesn't affect SQL Plugin functionality. If a database is using in-memory tables, when SQL Server 2014 is started, SQL Server will rebuild the database from the checkpoint files stored on the disk. Once the "In Recovery" state is cleared out, the user can open the Neverfail Heartbeat Management Client -> Applications tab -> Summary tab -> click the "Clear" button.
  • SQL Server 2012 File Tables are not supported. See Knowledgebase article #2495  - Neverfail for SQL Server Replication Stops in the Presence of SQL Server 2012 File Tables for more information (Ref-13103).
  • MSDTC.log file location changes are not replicated to the passive server(s) (Ref-13106).
    Workaround: Please see Knowledgebase article #2480  - Neverfail for SQL Server Plug-in Does Not Replicate MSDTC.Log File Location Changes to the Passive Servers.
  • Filter discovery does not protect database snapshots created outside of current database directory (Ref-13236).
  • SQL Server Plug-in reverts to the default LocalSystem account if incomplete username credentials are provided for filter discovery (Ref-13245).
  • When editing the User Account for Neverfail for SQL Server Plug-in, if the Local System account is used, it must be entered with initial caps ("Local System"). Using all lowercase characters will result in the plug-in failing to authenticate (Ref-13246).
  • The tempdb.mdf and templog.ldf files are protected when deploying with SQL Server 2004 SP4; this may cause degraded system performance when the Alter Index runs (Ref-13193).
    Workaround: Manually create Exclusion File Filters for the tempdb.mdf and templog.ldf files to prevent the additional overhead caused by replicating temp files.
  • This version of SQL Server Plug-in does not support SQL Server 2012 Express Edition (LocalDB) version. Attempting to install Neverfail for SQL Server with LocalDB will cause Neverfail SQL Server/File Filter Discovery to fail with the following message:

    The SqlServer/File Filer Discovery failed with the following warning: File Filter Discovery: Plug-in task failed:Errors encountered. Some data may not be protected. Please see logs. (System.ApplicationException: Errors encountered. Some data may not be protected. Please see logs. at SqlServerNFPlugin.x1426749251740f8a.OnUpdateFileFilters())

    For more information about this issue, see  - SQL Server Filter Discovery Fails With The Message: System.ApplicationException: Errors encountered. Some data may not be protected.
