Note:
- You might not need to run DFHIHFS0 if you have installed an earlier release of CICS® TS, because CICS creates the /cicsts directory that is common to all releases of CICS. If you do need to run DFHIHFS0, run this job once only.
- You must grant RACF® ALTER ACCESS to the OMVS data sets before running DFHIHFS0.
- The /cicsts directory contains only directories, each being a mount point.
- CICS requires the MOUNT issued by DFHIHFS0 to access files stored in the file system, but the MOUNT command is lost when you re-IPL MVS. SDFHINST member DFHBPXP0 contains a MOUNT command for inclusion in a BPXPRMxx member of the SYS1.PARMLIB data set. The MOUNT command applies to the data set specified in the HFS0DSN parameter of the DFHISTAR job to be mounted at directory /pathprefix/usr/lpp/cicsts. Copy this command into a BPXPRMxx member of the SYS1.PARMLIB data set to ensure the mount is restored when MVS is IPLed.
- All steps of DFHIHFS0 must end with return code zero for the job to be successful.
