MQ-related CRON job setting

Recently my colleague was faced with the crontab issue. Below is the description:

1. CRON Tab

We developed a JAR where it connects to the Queue Manger and puts message into the Queue to kick start the WMB flow. We have created a Shell script to send message to the queue. It is successful by executing the Shell script manually where it connects to the Queue Manager and successfully put the message into the Queue.

Unfortunately, the CRON job failed to execute this script. After a few rounds of investigation we found out that this is due to the AIX Environment Setting. We need to set the environment variables at our Shell script as below before connecting to MQ:
. /opt/IBM/mqsi/6.1/bin/mqsiprofile

The default environment setting for CRON does not have the MQ Specific environment.
Therefore, when we are using server binding, we need in include this into our Shell script.
If the Shell is running externally as client, we do not need to include this.
