SP4

  • I am going to be upgrading our SQL Servers to SP4.  We are currently on SP3a Hotfix 878.

    From what I have read I believe there are no security patches in SP4.  Is this true?

  • I don't know about that but I would jump to hotfix 2040 because SP4 (2039) has a bug that stops the SQL seeing all the memory in your server if you are using memory beyond 2GB.

    Even if you aren't going to use memory above 2GB I would still apply the hotfix to save yourself some head scratching later on.

    SP4 has a number of performance enhancements as well.

  • That is correct. There have been no SQL Server related security patches since SP4. You can always verify by checking out here:

  • Sorry what I meant to ask is:

    There have been no security patches between SP3a hotfix 878 and the latest SP4 hotfix?

    Another question is:

    If I have to roll back I will not lose any data from my user databases?  From what I understand, the changes to the master db will be lost if you rollback, but there should be no effect on your user databases?

     

     

     

     

  • The release notes for SP4 say that it cannot be rolled back therefore take a full backup of everything before your attempt and install.

    That said, I have not had any problems where I have applied the SP. I always make sure that the patch is applied AFTER a restart of the MSSQLSERVER service. This ensures that you have a fresh rebuilt TEMPDB.

    I also make sure that I have plenty of disk space.
