I ahev a doubt that can we connect more then one PI MDB to each other in central PI MDB ?
Depending on what you are trying to accomplish you may want to consider utilizing the PI Asset Framework tools instead of the PI Module Database. In comparing the two tools one might say PI MDB is old and limited, whereas PI AF is new and full featured. An OSIsoft staff person may correct me, but the PI MDB is a legacy feature supported for those who utilized it and may still be utilizing it in their operation. OSIsoft still uses it for storing key configuration settings for your PI Data Archive.
I do know that modules can be copied and pasted in various capacities (Values, Hierarchy, etc.) and there is an 'Insert Link' capability, but mine is disabled in my development server (see image below). I believe that permits you to link to PI MDBs on other PI Data Archive servers.
With that said I still recommend migrating to PI AF because linking external tables, AF Databases, controlling all your security settings, etc. is pretty easy compared to trying to accomplish the same things in the PI MDB.
Hi Kajal. I would say James is on the right track in suggesting you try to have your application use AF. In short: an MDB belongs to a single PI server and there is no supported synchronization method (that I know of) to share a single MDB structure among multiple servers. Can you tell us a little more about why you're trying to combine MDBs?
