JQPRRCMD02 error message VTAM RECVCMD failed

Q:

I am upgrading my JQP installation and am getting the following error:
JQPRRCMD02 ** VTAM RECVCMD FAILED, RC:14 FB2:6D
What am I doing wrong?

A:

You should only receive this error if you are running JQP 2.4 or above. This error indicates AUTH=SPO has not been added to the JQP APPL statement.  Update your VTAM APPL definition for JQP, vary the major node inactive and back active, then start JQP.
