DB Integrity job failed (using Ola hallengren's script)

  • I am using Ola Hallengren's script for DB integrity so I tested the script 1st on our dev environment and the script ran successfully however, it failed on production server when I executed the same script. Both server are running on 2008 R2 (SP2). Below is the script which I have used.
    USE [DBMAINT]
    GO
    /****** Object:  StoredProcedure [dbo].[DatabaseIntegrityCheck]    Script Date: 12/10/2018 7:27:52 AM ******/
    SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO

    ALTER PROCEDURE [dbo].[DatabaseIntegrityCheck]

    This is the error I am getting.

    Unable to start execution of step 1 (reason: Variable SQLLOGDIR not found).  The step failed.

    Can someone guide me on how to fix this issue?

  • These are never fun to troubleshoot... it could be permissions, configuration of SQL, configuration of Ola's scripts.... Here's how I'd attack this:

    First, check the server settings to make sure they are the same

    USE master;
    GO
    EXEC sp_configure 'show advanced option', '1';
    RECONFIGURE;
    EXEC sp_configure;
    Run that on both machines and compare. Fix any differences (If you are not sure, assume Production is right and take one change at a time to the Dev environment and test, test, test). And it should go without saying, document any changes.

    Next, I'd check Server services for SQL - are the services run by the same users? Do those users have the same permissions on each server? Make changes one by one and test. Since the variable name is SQLLOGDIR, I'd check the Log directories for matching permissions.

    Once I'm reasonably sure the 2 environments are more or less similar, I'd fully uninstall Ola's scripts, download the latest versions, reinstall then try again.

    This is the error I am getting.

    Unable to start execution of step 1 (reason: Variable SQLLOGDIR not found).  The step failed.

    Can someone guide me on how to fix this issue?

    Have you checked the log file for the job. His script will create a log file and write on every run. Check the error log location and get some input.
