Keeping all copies of your database templates at the same level

Any time you install a new release of RACF®, or install a PTF that includes new templates, you need to insure that all three copies of the templates are at the same level. You use IRRMIN00 to do this. For a detailed description of the IRRMIN00 utility, see RACF database initialization utility program (IRRMIN00).

There are three cases to consider:

You install a new release of RACF, or a PTF that includes new templates and requires an IPL, and you remember to run IRRMIN00 PARM=UPDATE before you do the required re-IPL.
You install a new release of RACF, or a PTF that includes new templates and requires an IPL, and you re-IPL without running IRRMIN00 PARM=UPDATE.
You install a PTF that has new templates and does not require an IPL.
