I would prefer the code solution, but how do I create a second instance of TIB_session, TIB_Cursor, TIB_connection? Could some one provide me with an example please!

I normally start by creating a TIB_Session instance and then thereafter I use that instance as the Owner when I create the subsequent connections, queries, etc. Then, I have the thread do whatever is needed within that TIB_Session context.The rule of thumb is as long as you only have a thread active within a single TIB_Session's full context you are thread safe.Jason

Subject: [IBO] IBO and threadsI'm developing a threaded server and use IBO and Delphi XE4. But how do I create a IBconnection, IBcursor and IBsession for each thread? I tried putting the creation under threadvar. I can compile but gets a runtime error (read access error)
