Running applications in the WebSphere MQ client environment

We can run a WebSphere MQ application both in a full WebSphere MQ environment and in a WebSphere MQ client environment without changing your code, provided that:

• It does not need to connect to more than one queue manager concurrently

• The queue manager name is not prefixed with an asterisk (*) on an MQCONN or MQCONNX call

• It does not need to use any of the exceptions listed in What applications run on a WebSphere MQ client?

Note:

The libraries you use at link-edit time determine the environment in which your application must run.

When working in the WebSphere MQ client environment, remember that :

• Each application running in the WebSphere MQ client environment has its own connections to servers. It will have one connection to each server it requires, a connection being established with each MQCONN or MQCONNX call the application issues.

• An application sends and gets messages synchronously.

• All data conversion is done by the server, but see also MQCCSID.
