从Delphi应用程序连接到同一台计算机上的Interbase服务器

Question

I have an XE8 project that (is supposed to) access an Interbase server running on the same machine. A few days ago it was working fine, but has developed the problem that if I attempted to set the Connected property of a TIBDatabase component to True , either in the IDE or in code at run-time, I get the error:

Connection rejected by remote interface

Attempting to connect to the server using the IBConsole utility also produces this error.

I've cleared as much of Interbase as I can find from the machine & its registry and re-installed it but the problem persists. Googling the message text finds a modest number of things, but I've tried the few suggested solutions to no useful effect.

Btw, the PortQry utility confirms that port 3050 is open and that the gds_db server is listening.

My question, obviously, is does anyone recognise this symptom and know how to fix it?

Answer 1

I eventually found the cause of this problem. I have an instance of the Firebird server installed on the problem machine and set up as a service, and at some point recently, its Startup Type had been changed from Disabled to Automatic and the fact that it was running was evidently causing the IB server to misbehave. Reverting it to `Disabled' caused the problem to vanish.

I imagine that it was actually the FB server that was the 'remote interface' that was rejecting the connection.
