Notes:
- Source for the C samples is in the file QMQMSAMP/QCSRC. Include files exist as members in the file QMQM/H.
- Source for the COBOL samples are in the files QMQMSAMP/QCBLLESRC. The members are named AMQ0
xxx4, wherexxxindicates the sample function. - Source for the RPG samples is in QMQMSAMP/QRPGLESRC. Members are named AMQ3
xxx4, wherexxxindicates the sample function. Copy members exist in QMQM/QRPGLESRC. Each member name has the suffix G. - The executable version of the IBM MQ MQI client samples share the same source as the samples that run in a server environment. Source for the samples in the client environment is same as the server. IBM MQ MQI client samples are linked with client library LIBMQIC and IBM MQ server samples are linked with server library LIBMQM.
- If client executable for sample application of Reconnectable client and asynchronously consumer application has to be run, it has to be compiled and linked with threaded library LIBMQIC_R. Hence, it has to be run in threaded environment. Set the environment variable QIBM_MULTI_THREADED to 'Y' and run the application from qsh.
See Setting up IBM MQ with Java and JMS for more information.
In addition to these, the IBM MQ for IBM i sample option includes a sample data file, which you use as input to the sample programs, AMQSDATA and sample CL programs that demonstrate administration tasks. The CL samples are described in the Administering IBM i . You could use the sample CL program amqsamp4 to create queues to use with the sample programs described in this topic.
