I am using SQL Server 2008. I am confused about which account will be used when a SQL Server agent job runs. My confusions are,

  1. SQL Server agent as a Windows Service which we could control from Windows Service Management Console, from there we could set the account to run SQL Server Agent (LocalSystem in my computer);
  2. Could I set SQL Server agent job level account to run on?
  3. Could I set in each step which account SQL Server agent job step will run on?

I have above confusions because 3 different account systems may be used and my concern is what is the actual account each step will run on, and I want to avoid any permisson issues (i.e. I want to make sure the account have enough permission.). Any comments or advice? Appreciate anyone could clarify the 3 levels of accounts, which makes me very confused.

thanks in advance,
George

Need An Account,

    I would typically run the SQL Server Agent jobs under the same account as your app accesses the database.

    If that account is too limited in its permissions (which might be a good thing!), I would create a single account for that app and all its SQL jobs (if that’s possible) and run all SQL jobs under that account.

    You could potentially run each step under a different account, but I wouldn’t use that in general (it just makes it really hard to know and understand what is run under which account). Only use it if you have to run a particularly sensitive step that needs a bunch of extra permissions and those permissions are only available to a particular system account or something.

    The account under which the SQL Server Agent windows service runs really doesn’t have an impact on what your job steps will be run under.

    So it boils down to really just two accounts:

    • one account is needed to run the SQL Server Agent Windows service – this is a Windows account on your machine / server which needs to have enough permissions to run the service, start and stop it – either use LocalSystem, Network Service, or whatever other Windows account you have to run services with

    • The other account would be the account to run your SQL Server Agent steps under – that’s typically a SQL Server account (which could be based on a Windows account), and it needs enough privileges inside SQL Server to do its job, e.g. it needs access to the database objects and all. I would strive to have just one account for each app that runs the SQL Server jobs – makes life a whole lot easier!

    PS: To set the user to run a step under, you need to use the “Advanced” page on the Job step property dialog and select the user from a popup window:
