Recovery manager utility program (DFHRMUTL)

This section describes the recovery manager utility program, DFHRMUTL, for overriding the type of CICS® startup produced by a START=AUTO, and improving the performance of cold and initial starts.

Note:
For detailed information about the type of startup produced by each possible combination of START setting, global catalog and system log contents, and autostart override, see the CICS System Definition Guide.

DFHRMUTL processes the global catalog data set. It can insert or modify the recovery manager autostart override record. Optionally, it can extract a subset of the catalog records to build a reduced new catalog for a cold start.

You can use the recovery manager utility program to:

DFHRMUTL sets a return code indicating if it has succeeded.

You can specify what you want DFHRMUTL to do by supplying parameters in a single optional record in the input data set, SYSIN. See Specifying parameters for DFHRMUTL.

You may need to supply one or two CICS global catalog data sets:

DFHGCD
The catalog from which a copy is extracted or, if no copy is being made, the one in which the autostart override record is placed.
NEWGCD
The catalog which is cleared and receives the copy, if one is requested.

DFHRMUTL writes some or all of the following to the output data set, SYSPRINT:

The catalogs DFHGCD and NEWGCD may be updated. If no copy is requested, DFHGCD may have an override record inserted, or updated. If a copy is requested, DFHGCD is unchanged, NEWGCD is cleared, and the copy and new override record written to NEWGCD.
