Maintaining state in VFP COM+ components
Today I got the following email from a VFP developer:
We are looking to a way to distrubute the application server load (FoxPro MTDLL) by using a COM+ clustering configuration. Question: How FoxPro COM+ state will replicated through all cluster members? The COM+ are mainly to access MS SQL DB.
The answer is:
You can never count on state being replicated across servers. COM+ itself is designed to be stateless. You'll need to keep state information in a central location, for example SQL Server, or send all the state information every time you CREATEOBJECT() on a COM+ object.
