First, you need to decide how many time blocks or hours you want the jobs to run in. So let’s start with scenario one where you pick for example four time blocks. First, you declare a variable with the time block in it and we will feed in the @@SERVERNAME to let determine a value for the time block that server will run. Then we wrap our code around our time block, our example we will run Index Maintenance for a 12 period spread out for three hours. Mind you for my index process which I probably should blog about as well I am processing one index at a time have something that BREAKs out of the procedure when it exceeds the time block it is. So below we run Index Maintenace between start the index maintenance job on a server between the hours 6 PM and 5 AM based on the time block value we got back.
