The Wiert Corner - irregular stream of stuff: jpluimers

A couple of notes on NMQ_MQ_LIB and the WebSphere MQ aka MQSeries client libraries:

• NMQ_MQ_LIB specifies the MQ DLL to use
• Depending in your interface, the NMQ_MQ_LIB can be an environment variable, application setting, or hardcoded DLL name
• MQSeries 5.x and WebShpere MQ 6.x require you to specify the bitness in the MQIC DLL name (they don’t accept mqic.dll, but require mqic32.dll) when you access it from the C or Delphi interface.
  MQM DLL does not require bitness: it is mqm.dll in all versions.
• From client applications, use mqic.dll or mqic32.dll.

And a few links:

• C# – .NET client connecting to IBM MQ over SSL – Stack Overflow.
• WebSphere MQ 7: defining which connection type to use.
• WebSphere MQ 6: defining which connection type to use.
• MQSeries.net :: View topic – Connecting to an MQ Server without MQ Client installed.
• MQSeries.net :: View topic – NMQ_MQ_LIB=MQIC32.dll.

I needed this to get some apps talking to MQ on AS/400 aka iSeries aka System i working correctly by getting the DLLs right.
