Java dependent regions
You can start two types of Java™ message-driven dependent regions, either a JMP or a JBP region.
The JMP region is similar to an MPP region and is started in the same manner as an MPP region. The default job name is IMSJMP.
The JBP region is similar to a BMP region and is started in the same manner as a BMP region. The default job name is IMSJBP.
