MQSeries::Command fails for type MQSC

Hi Hildo, Hope it's all going well. We've found a bug in the MQSeries::Command code which means MQSC commands fail to parse the returned messages properly. The error message seen in Debug mode is this: [Fri Mar 4 14:03:43 2005] qStatus.pl: Unrecognized MQSC buffer: +MQDX QUEUE(TSTEUCLR.REMOTE ) TYPE(QREMOTE ) [Fri Mar 4 14:03:43 2005] qStatus.pl: at /var/mqm/home/perl/MQSeries/Queue.pm line 581 We have determined where the error is occurring. Line 825 of Base.pm looks like this: $buffer =~ s!^\*\S+\s+!!; We added a second line like this: $buffer =~ s!^\+\S+\s+!!; and this solved our problem. However, this works for us because we use the command prefix +qmgr, e.g. +MQD1. This value is user definable so I think it will require a bit of thought to make it more generic. Having said that, it may not be too long before we can dispense with MQSC on the mainframe entirely ;-) Cheers, Paul

This is an ongoing issue that'll be hard to resolve generically - parsing MQSC is just to darn unreliable. For what it's worth, I recommend a slightly different patch to the parser, having one regexp instead of two: old: $buffer =~ s!^\*\S+\s+!!; new: $buffer =~ s!^[\+\*]\S+\s+!!; I'll add this patch to release 1.24 of the MQSeries module, but please don't hold your breath for a release - I aim to add MQ V6 support to it, wait for MQ V6 to be GA, and then release it. And yes, I aim to support PCF for the mainframe, and then let MQSC support bitrot... Please let me know whether the sugegsted patch solves your issue and I'll close the ticket.

Hi Hildo, Yes, that is a bit more elegant and it works for us. So this match will work for anyone who's using a Command Prefix starting with either a + or a *. I agree it's difficult to think of a good, generic solution but at least it's fairly easy to update this for anyone using other characters until we all roll out Version 6! Cheers, Paul
