Specifying disk volumes

To make the best use of your disk space, you can specify your own disk volumes and device types to be used to install CICS® Transaction Server.

If you intend to install CICS Transaction Server into disk space managed by the storage management subsystem (SMS) component of MVS/DFP, you do not have to specify your own disk volumes; SMS can determine device assignment. In this case, proceed to Specifying SMP/E zone attributes. For further information about installing system-managed storage and about planning for and migrating storage to an SMS-managed environment, see z/OS DFSMSdfp Storage Administration

You can specify your own disk details using the following parameters:

DEFVOL volume disktype
Defines the default disk on which the contents of the disk volumes CMACVOL, DISTVOL, OPTVOL, SMPVOL, and TARGVOL resides if the appropriate parameter is not coded in the DFHISTAR job. For example, if you do not code the DISTVOL parameter, the CICS Transaction Server distribution libraries resides on the disk defined by DEFVOL.
volume
Is one of the following entries:
  • The volume serial identifier, in the range 1 through 6 characters, of the default volume.
  • A period (.) if all volumes other than CMACVOL and SMPVOL that are not specifically defined by the appropriate parameter of the DFHISTAR job are put onto any available volume. The CMACVOL and SMPVOL volumes are put onto the same volume as the library specified by the TEMPLIB parameter.
disktype
Is the UNIT parameter of the volume.

If you omit the DEFVOL parameter, all volumes that are not specifically defined by the appropriate parameter of the DFHISTAR job are put onto the same volume as the library specified by the TEMPLIB parameter.

DISTVOL volume disktype
Defines the disk on which the CICS Transaction Server distribution libraries resides.
volume
Is one of the following entries:
  • The volume serial identifier, in the range 1 through 6 characters, of the volume on which the distribution libraries resides.
  • A period (.) if the CICS Transaction Server libraries are to be put onto any available volume.
disktype
Is the UNIT parameter of the volume.
If you omit the DISTVOL parameter, the distribution libraries are put on the volume specified by the DEFVOL parameter. If the DEFVOL parameter is omitted, or if a period (.) is specified for its volume operand, the distribution libraries are put onto any available volume.
TARGVOL volume disktype
Specifies details of the disk containing the CICS Transaction Server target libraries.
volume
Is one of the following entries:
  • The volume serial identifier, in the range 1 through 6 characters, of the volume on which the CICS Transaction Server target libraries are to reside.
  • A period (.) if the CICS Transaction Server target libraries are to be put onto any available volume.
disktype
Is the UNIT parameter for the volume.
If you omit the TARGVOL parameter, the CICS Transaction Server target libraries are put onto the volume specified by the DEFVOL parameter. If the DEFVOL parameter is omitted, or if a period (.) is specified for its volume operand, the CICS Transaction Server target libraries are put onto any available volume.
SMPVOL volume disktype
Specifies the disk that contains the permanent, non-VSAM SMP/E data sets for CICS Transaction Server that are associated with global or distribution zones and are therefore unique.
volume
Is one of the following entries:
  • The volume serial identifier, in the range 1 through 6 characters, of the volume on which the permanent non-VSAM SMP/E data sets are to reside.
  • A period (.) if the permanent non-VSAM SMP/E data sets are to be put onto the same volume as the library specified by the TEMPLIB parameter.
disktype
Is the UNIT parameter for the volume.
If you omit the SMPVOL parameter, the permanent non-VSAM SMP/E data sets for CICS Transaction Server are put on the volume specified by the DEFVOL parameter. If the DEFVOL parameter is omitted, or if a period (.) is specified for its volume operand, the data sets are put onto the same volume as the library specified by the TEMPLIB parameter.
OPTVOL volume disktype
Specifies details of the disk onto which the optional source material is copied.
volume
Is one of the following entries:
  • The volume serial identifier, in the range 1 through 6 characters, of the volume on which the optional source material is to reside.
  • A period (.) if the optional source material is to be put on any available volume.
disktype
Is the UNIT parameter of the volume. This is required only if volume is specified.
If you omit the OPTVOL parameter, the optional source material is put on the volume specified by the DEFVOL parameter. If the DEFVOL parameter is omitted, or if a period (.) is specified for its volume operand, the optional source material is put onto any available volume.
CMACVOL volume
Defines the disk on which the VSAM KSDS, DFHCMACD, resides. This data set is used for the CICS Transaction Server messages facility (CICS-supplied transaction CMAC).
volume
Is one of the following entries:
  • The volume serial identifier, in the range 1 through 6 characters, of the volume on which the VSAM KSDS, DFHCMACD, is to reside.
  • A period (.) if the DFHCMACD data set is to be put onto the same volume as the library specified by the TEMPLIB parameter.
If you omit the CMACVOL parameter, the DFHCMACD data set is put onto the volume specified by the DEFVOL parameter. If the DEFVOL parameter is omitted, or if a period (.) is specified for its volume operand, the DFHCMACD data set is put onto the same volume as the library specified by the TEMPLIB parameter.
