Creating data sets unique to each CICS region, DFHDEFDS job

You can use the DFHDEFDS job to delete and recreate copies of the following data sets for each CICS® region.

Name
Data set
DFHADEM
Resource manager for enterprise beans.
DFHAUXT
Non-VSAM auxiliary trace (A).
DFHBRNSF
Bridge.
DFHBUXT
Non-VSAM auxiliary trace (B).
DFHDMPA
Non-VSAM dump (A).
DFHDMPB
Non-VSAM (B) dump.
DFHEJDIR
Bridge.
DFHEJOS
Object store.
DFHGCD
Global catalog.
DFHHTML
HTML template data set.
DFHINTRA
Intrapartition transient data.
DFHLCD
Local catalog.
DFHLRQ
Local request queue.
DFHTEMP
Temporary storage.
FILEA
Sample program data.
DFHDPFMB
The debugging profiles base data set.
DFHDPFMP
The debugging profiles path data set.
DFHDPFMX
The debugging profiles alternate index data set.

Use DFHISTAR to create a copy of the DFHDEFDS job for each CICS region. Edit DFHISTAR, specifying the parameters DSINFO and SELECT, and run it once for each region.

In DFHISTAR, specify the following parameters:

The format of the data set names is:

dsindex.CICSqualifier.dsname
dsindex
is the high-level index for the data sets, specified on the DSINFO parameter of DFHISTAR. The default is hlq.
qualifier
is the region qualifier for the data sets that are used by this CICS region, specified on the DSINFO parameter of DFHISTAR. The default is no qualifier.
dsname
is the name of the data set being defined.

For example, the default name for the CICS local catalog is hlq.CICS.DFHLCD.

The DFHDEFDS job comprises the following job steps:

  1. DELETE any existing copies of the data sets
  2. DEFINE defines the clusters for the data sets
  3. INITDP initializes the debugging profiles base data set
  4. DEFALT defines the alternate index for the debugging profiles data set
  5. BLDDP builds the alternate index for the debugging profiles data set
  6. INITGCD initializes the CICS global catalog
  7. INITLCD initializes the CICS local catalog
  8. DEFTRACE defines the trace data sets
  9. DEFDUMP defines the dump data sets
  10. LOADFILE loads the sample data into the FILEA data set
  11. LOADHTML loads HTML templates for CICS supplied transactions.
