Use Maximo webservice with JSON content

While the JSON API in newer version of Maximo is quite useful, for many integration scenarios, I still prefer to use the old API infrastructure with Publish Channel and Web Service. However, the native format for this feature is XML.

To send or receive JSON with Publish Channel or Enterprise Service, we can translate the default to JSON format before it goes out / into the system. Below is a simple example to set it up.

Setup standard Publish Channel to send XML message

Message Engine doesn't start after setting up cluster

This issue hit me a few times and always took me some time to figure out what happened. So I thought it's a good idea to note it down.

Symptom:

When setting up cluster environment for Maximo, I will need to setup an integration bus with a message engine for each cluster (IF, UI, Cron etc.)

Each message engine will require its own individual schema (and thus individual user if the Oracle DB is used)

After integration bus are setup and Maximo cluster started, we see a lot of errors in the log file, usually in the Cron or MIF cluster due to message engine is not available.
