Java/PCF Program to Delete an IBM MQ Channel

A couple of days ago, I posted a Java/PCF program that would create a IBM MQ channel. So, if you require creating a channel via Java/PCF then you probably will need to delete a channel via Java/PCF. If you are used to deleting an IBM MQ channel using runmqsc command then the following simple Java/PCF […]

Java/PCF Program to Create an IBM MQ SVRCONN Channel

A couple of weeks ago, I posted a Java/PCF Program to Create an IBM MQ Queue. So, today I thought I would create a Java/PCF program to create an IBM MQ SVRCONN channel If you are used to creating an IBM MQ channel using runmqsc command then the following simple Java/PCF program will create a […]

Java/PCF Program to Create an IBM MQ Queue

The other day, someone on StackOverflow asked about creating an IBM MQ queue from JMS. I know it is possible to send PCF commands as a JMS message to the Command Server but it seems overly complex when you can simply do it from Java/PCF (non-JMS). If you are used to creating an IBM MQ […]
