Data Set Types

The data sets are of the following types:

Distribution

Consists of SMP distribution libraries that are used during the installation and maintenance of a product, for example, dsnpref.OPB9.ccdsname.

Local PDS

Consists of run-time PDS files that are allocated during setup for use by an active region, and cannot be shared between multiple regions, for example, dsnpref.rname.dsname.

Local Sequential

Consists of run-time sequential files that are allocated during setup for use by an active region, and cannot be shared between multiple regions, for example, dsnpref.rname.dsname.

Local VSAM

Consists of run-time VSAM files that are allocated during setup for use by an active region, and cannot be shared between multiple regions, for example, dsnpref.rname.dsname.

Other PDS

Consists of shared non-VSAM PDS created separately to this product.

Run-time PDS

Consists of shared non-VSAM SMP target files that are allocated during installation and used by an active region, for example, dsnpref.OPB9.ccdsname.

Run-time PDS (external)

Consists of shared non-VSAM SMP target libraries that are not used by a region.

Run-time PDSE

Consists of shared non-VSAM SMP target files that are allocated during installation and used by an active region, for example, dsnpref.OPB9.ccdsname. Program objects that must be executed from a PDSE are stored in these files.

Shared PDS

Consists of run-time PDS files that are allocated during setup for use by an active region, and can be shared between multiple regions, for example, dsnpref.OPB9.dsname.

Shared run-time VSAM (MODSDIS, NETINFO, NSCNTL, PANLDIS, OSCNTL, and UAMS)

Consists of files identified by the unique data set prefixes you enter when you set up your regions. You can choose to select a data set prefix for each file. You can make the data set prefix the same or different from those prefixes you have used for other files.

Active regions can share these run-time files.

VSAM data sets that can be shared in this manner are defined using SHAREOPTIONS(3,3).

Staging

Consists of shared non-VSAM files that are used during the installation process to store sequential copies of files including the product panels, MODS, and OSCNTL files, for example, dsnpref.OPB9.ccdsname.S. These sequential copies are then merged to create the run-time files. If you intend to create additional regions at a later date, you can use the staging files as input to the setup process.

TESTEXEC

Is a file identified by the unique data set prefix you enter when you set up your region.
