IBDAC 4.0.1 + FB 2.5.1: Error "Invalid parameter in TBP"

Hi,

today I installed FB 2.5.1 x64 for testing purposes and now I have some problems with IBDAC (latest 4.0.1):

Connection works fine. When I try to load some data, I got the following error massage every time:

"Invalid parameter in transaction parameter block. Found more than one transaction isolation in TBP."

It has the error code -901 with SQL-Message "Unsuccessfull execution caused by system error that does not preclude successful execution of subsequent statements"

Befor installing FB 2.5 I worked with FB 2.0.6 (x32) and everything works fine.

Any idea what is going wrong here?

My environment: Delphi XE Pro German, Win7 Pro x64, FB 2.5.1 (x64), IBDAC 4.0.1

Greetings

Udo Treichel

Please check that you don't have several transaction isolation levels (concurrency, read_committed, consistency) in transaction parameters. If there is only one transaction isolation level in transaction parameters, please try creating a small sample to demonstrate the problem and send it to andreyz*devart*com.
