Verifying the recovery fault recording setup

To verify the setup of recovery fault recording, insert a JCL statement like the following into the abending step of any of the other IVP jobs, for example, the HFZVPCOB IVP job (see Verifying the use of Z Abend Investigator with COBOL):

//GO.HFZRFRON DD DUMMY

When the HFZRFRON ddname is allocated to the abending step being analyzed by Z Abend Investigator, then a deliberate abend U0777 is issued. This abend activates the recovery fault recording feature to write a TDUMP or SDUMP depending on the setup described in Recovery fault recording, and a recovery fault recording fault entry.

Before submitting the job, ensure that the HFZS subsystem is started.

Messages similar to the following should be displayed:


+HFZ0001I Z Abend Investigator V1R1M0 (AHFZ110  2019/11/22) invoked by HFZXCEE using SYS1.PARMLIB.F1.USER(HFZCNF00)
+HFZ0157I Z Abend Investigator about to deliberately abend U0777 and take RFR dump due to HFZRFRON DDname
+HFZ0047S HCL Z Abend Investigator internal abend. U0777

IEA822I COMPLETE TRANSACTION DUMP WRITTEN TO HFZRFRHQ.TDUMP.F1.D181215.T013821.S00072

Reanalysis of the recovery fault recording fault entry identified in message HFZ0126I should result in a report, which is almost identical to the one from the same IVP run without the HFZRFRON DD statement.
