Fix for IBM Rational Developer for z System 22.214.171.124 Host (FMID HHOP951).
In version 9.5.1, the RSE and JES Job Monitor related functions moved from IBM Rational Developer for z Systems to another product, IBM Explorer for z/OS. IBM Explorer for z/OS is now a prerequisite for IBM Rational Developer for z Systems. This implies that Rational Developer for z Systems must be reinstalled. There is no PTF to bring version 9.5 to version 9.5.1.
Refer to the IBM Explorer for z/OS support page for their recommended fix list or go directly to the Mainframe Dev - Eclipse Tools site for the latest IBM Explorer for z/OS PTF.
