Scheduling is a big issue in MIIS and, when new to it, it seems rather odd that there is no native scheduling within the basic application. <\/span><\/span><\/p>\n

I expect most people quickly find out about MASequencer from the <\/span>MIIS Resource Toolkit<\/span><\/a>, and this isn’t a bad starting point. With MASequencer you can create series of MIIS tasks to run in a particular order, each with optional pre- and post-steps, which may include other external process, such as firing off a DTS package, or running another script. Once you have your sequences configured, use the Windows Scheduler to automate them.<\/span><\/span><\/p>\n

I think this approach would probably work fine for a simple MIIS system, but mine quickly outgrew it. The best practise, as far as I can see, is to ensure that only one MIIS job is running at a time – more than that and you risk SQL process blocking. So how closely should you schedule your MASequencer tasks? Too close and you risk process blocking; too far apart and your Delta imports will take even longer.<\/span><\/span><\/p>\n

With MASequencer I couldn’t change the tasks for different circumstances. What’s the point of running an Export if there is nothing waiting to go out? When the Export must be followed by a Full Import\/Sync (as is the case for certain MA types) you are slowing down your system and filling up your <\/span>Run History<\/span><\/a> for no good reason.<\/span><\/span><\/p>\n

The answer to all these problems is to be found in the WMI Provider. For a good introduction read About the WMI Provider<\/a> in the MIIS Developer’s Reference.<\/span><\/span><\/p>\n

I ended up writing my own scheduling mechanism in VBScript: more on that to come<\/a>.<\/span><\/span><\/p>\n\n\n
