SAS code that uses the Interface to WebSphere MQ may fail with the
following message:

   MQCONN: failed with reason= -1

The code may fail in SAS 9 even if the code ran successfully in SAS 8.2.

There are 3 items that need to be in place in order to run SAS 9 code
that interfaces with WebSphere MQ:

  1.) Installation of the WebSphere MQ 64-bit client libraries on the
      server.

      The installation of the client libraries can be found in a support
      pack found on IBM's site: (download the client libraries for the
      appropriate system)

http://www-306.ibm.com/software/integration/support/supportpacs/category.html#cat3


    ie.  MQSeries Client Libraries for HP-UX (64-bit)
         WebSphere MQ Client for Windows - V5.3
         MQSeries Client Libraries for AIX (64-bit)

     The page contains installation instructions and links to libraries
     and headers.  Only the libraries are needed to run with the SAS
     Interface to Messaging.

  2.) Set the WebSphere MQ environment variable "MQSERVER" to point to
      Queue Manager.

  3.) Set the MQMODEL variable in SAS before making any MQ calls:
      %let MQMODEL=CLIENT;

Check the following link for details on setting the MQMODEL variable in
SAS.
