Load error : file 'MVS_JOB_STEP_RESOURCE_MGR'

Problem:

The error shown below occurs when attempting to run an IMS transaction in Enterprise Server:

Load error : file 'MVS_JOB_STEP_RESOURCE_MGR', .

141111 10232263       2292 MFTEST   CASSP0014S Process termination due to RTS error.
Load error : file 'MVS_JOB_STEP_RESOURCE_MGR'

141111 10232283           CASCD1056S IMS MPR Process for Server TESTSVR abended by signal 00011 10:23:33

Resolution:

The PATH variable was specified incorrectly.  It was missing a "\\".

This error can also occur if you are attempting to use Code Watch to debug a program, and it cannot load it. In this instance, it was not being used.

It's always a good idea to check your Env.Var. within ESMAC, to verify the environment variables as Enterprise Server sees them.
