The WebSphere MQ layer
This is the second layer we should install and test—if this layer does not work then Q replication will not work!
We can either install the WebSphere MQ Server code or the WebSphere MQ Client code. Throughout this book, we will be working with the WebSphere MQ Server code.
If we are replicating between two servers, then we need to install WebSphere MQ Server on both servers. If we are installing WebSphere MQ Server on UNIX, then during the installation process a user ID and group called mqm
are created. If we as a DBA want to issue MQ commands, then we need to get our user ID added to the mqm
group.
Assuming that WebSphere MQ Server has been successfully installed, we now need to create the Queue Managers and the queues that are needed for Q replication. The details of what we need to create for each scenario are discussed in Appendix A. This section also includes tests that we can perform to check that the MQ installation and setup is correct. The following diagram shows...
