Converting to DFSMSrmm from CA-1

Chapter 6. Data extraction 225

6.2.4 CA-1 PARMLIB options

Review carefully all of the CA-1 PARMLIB options before proceeding. Pay

particular attention to the CA1.PPOPTION members, which include most of the

system options.

You must modify the DFSMSrmm options to reflect the same defaults as

specified in the CA-1 options. The most important DFSMSrmm options for the

conversion are:

 OPTION statement:

–OPMODE parameter

– BLP parameter

– CATSYNC parameter

– MASTEROVERWRITE parameter

– RETPD parameter

TMSXEXP Allow modification of the

expiration date and eligible for

RDS indicator or the TMC

record update to be bypassed.

You can use either the TSO RMM subcommands, the

ISPF dialog, or the API to change any information in the

DFSMSrmm CDS. To change the volume status from

MASTER or USER to SCRATCH you need the batch

utility, EDGHSKP,PARM=

′EXPROC.′

TMSXOCAT Use for MVS catalog and TMC

synchronization.

Use the EDGHSKP and EDGUTIL utilities to

synchronize the DFSMSrmm control data set with user

catalogs.

TMSXTPNT Reject volume for label

processing.

You can define and delete volumes at any time with out

having to take

DFSMSrmm Implementation and

Customization Guide

, SC26-7405 out of service. In

DFSMSrmm you need not define volume groups or

volume ranges.

TMSXTPPR Provide various options to

control the processing of

tapes.

- -

TMSXVLT1 Allow TMC record selection

for vault management system

processing.

The retention and movement policies you define to

DFSMSrmm are known as VRSs. You use them to say

how long and where you want to keep data sets or

volumes. You also use them to define how volumes are

to be moved among the libraries DFSMSrmm supports,

and the storage locations defined for vital records, and

disaster recovery purposes. All information about

storage location management processing is stored in

the DFSMSrmm CDS.

CA-1 function DFSMSrmm equivalent

226 Converting to DFSMSrmm from CA-1

– TPRACF parameter

– UNCATALOG parameter

– VRSJOBNAME parameter

– VRSEL parameter

 VLPOOL statement

Only if you use multiple scratch pool support

 LOCDEF statement

Only if you use location names different from the installation defaults

The CA-1 PARMLIB options should be input to the conversion tools so that the

relevant values for policy creation can be used when the DFSMSrmm VRS

records are built. Other than the VRS creation, the CA-1 PARMLIB options must

be manually converted to DFSMSrmm options.

Table 6-7 lists the CA-1 PARMLIB options and their DFSMSrmm equivalences.

Table 6-7 CA-1 PARMLIB options and DFSMSrmm equivalences

Option

CA-1 DFSMSrmm

Preferred date format

DATEFMT

Specifies the default format of the date

DATEFORM

Specifies the default format of the date:

mm/dd/yyyy - American

dd/mm/yyyy - European

yyyy/mm/dd - ISO

yyyy/ddd - Julian

SCRPOOL scratch pool management

SCRPOOL

Defines ranges or subranges of scratch pools

VLPOOL

Use the VLPOOL command in PARMLIB to define

pools. When you add a new volume to the library,

DFSMSrmm assigns it a shelf location from the

specified pool.

Chapter 6. Data extraction 227

Assignment control statement

DSN / JOB / POOL

Assigns a data set to a tape pool

EDGUX100

Installation-wide exit, EDGUX100, can be used to

assign data sets to a specified scratch pool.

Refer to

DFSMSrmm Implementation and

Customization Guide

, SC26-7405, or to “How the

conversion process works” on page 315 for an

example of how the VRSTABLE is used by

EDGUX100.

Specific mount message intercept

XMSG

Prefixes specific mounts with special message

IDs

MNTMSG

Use the MNTMSG command to tailor mount and

fetch messages so they display the volume serial

number and pool name or rack number.

Label change action

LCHG

Changes label if the label type of a tape mounted

to satisfy a request is different from that specified

in the JCL

BLP

Specifies how DFSMSrmm controls BLP. If

BLP(RMM) is specified, you can use BLP for input

from and output to volumes in user status and for

input from volumes in master status. When the

BLP(NORMM) option is specified, you can use BLP

for input from and output to volumes in user and

master status and for output to scratch tapes.

If the label is being changed and you are not using

BLP, you also need access to the profile in the RACF

FACILITY class:

STGADMIN.EDG.LABEL.volser

or

STGADMIN.EDG.NOLABEL.volser

Option

CA-1 DFSMSrmm
