Searching for resources specified by a print job

The locations where resources are stored depend on the resource type. Resource types are stored in these locations:

Inline in the print data set

All resource types

System and user path libraries

Extended code pages
Object containers (also called data object resources)
TrueType and OpenType fonts

System and user PDS or PDSE libraries

FOCA fonts
Form definitions
Object containers
Overlays
Page definitions
Page segments

See Table 2 for examples of resource types.

When a resource is referenced by a print data set, PSF only searches the locations where that resource type can be stored. PSF searches for the resource in this order:

If a resource can be activated by PSF, resources that are resident in the printer.

If PSF finds an Invoke Medium Map (IMM), internal copy groups immediately preceding IMM records in the print data set.

Inline resources in the print data set.

Resources in user path libraries.

Resources in user PDS or PDSE libraries in the order they are specified.

Resources in system path libraries.

Resources in system PDS or PDSE libraries in the order they are concatenated.

Notes:

PSF truncates the resource name to eight characters when searching PDS or PDSE libraries.
Only the security libraries (if PSFMPL is active) and the system libraries are searched for resources to be used on auxiliary data sets. For B1 security information, see PSF for z/OS: Security Guide.
An overlay called out in the Printer Inventory or the PRINTDEV is always loaded from the system libraries.
For soft IOCA resources, which are those not specified in the data stream with the MDR structured field, PSF searches the system PDS or PDSE libraries before searching the system path libraries.
