MQSeries.net :: View topic - ETC, BlockIP2 and TXSeries issue in the same host

camauz · Posted: Tue Jun 03, 2008 6:15 am Post subject:

Hi all,
first I'm describing the architecture:
TXSeries 6.2 (AIX 5.3)
WebSphere MQ Extended Transactional Client 6.0 (AIX 5.3)
BlockIP2 2.69 (AIX 5.3)
WebSphere MQ 6.0 (AIX 5.3)

The original problem: assign a different MCAuser to client connection opened by TXSeries (CICS) via Extended Transactional Client (ETC).
We have configured the BlockIP2 exit (http://www.mrmq.dk/BlockIP2.htm) to implement MCAuser definition on the fly.

All this stuff run OK if the TXSeries region and the WSMQ queue manager are on different hosts (different IP addresses).
If the TXSeries region and the WSMQ queue manager are running on the same host (same IP address), the client connection stops immediately after start and the XA protocol peeks up an error.
The configuration seems to be "the same" in both scenarios, so I'd would appreciate someone else with a similar problem using BlockIP2:
- can it be used in an unrestricted way when client and server are in the same host?

I'm appending a piece of log of BlockIP2:

Any hints?
Thanks in advance
