Input Parameters

Input parameters for the function routine are:

SSOB
SSIB
IAZSSJP
IAZJPCLS (Job Class Information)

SSOB Contents: The caller sets the following fields in the SSOB control block on input:

Field Name: Description
SSOBID: Identifier 'SSOB'
SSOBLEN: Length of the SSOB (SSOBHSIZ) control block
SSOBFUNC: SSI function code 82 (SSOBSSJP)
SSOBSSIB: Address of the SSIB control block or zero (if this field is zero, the life-of-job SSIB is used). See Subsystem Identification Block (SSIB) for more information about the life-of-job SSIB.
SSOBINDV: Address of the function-dependent area (IAZSSJP control block)

Set all other fields in the SSOB control block to binary zeros before issuing the IEFSSREQ macro.

SSIB Contents: If you do not use the life-of-job SSIB, the caller must provide an SSIB and set the following fields in the SSIB control block on input:

Field Name: Description
SSIBID: Identifier 'SSIB'
SSIBLEN: Length of the SSIB (SSIBSIZE) control block
SSIBSSNM: Subsystem name: name of the subsystem to which this JESPLEX Information Services request is directed.

Set all other fields in the SSIB control block to binary zeros before issuing the IEFSSREQ macro.

IAZSSJP Contents: The caller must set the following fields in the IAZSSJP control block on input:

Field Name

Description

SSJPID

Eyecatcher for the control block (set to 'SSJP')

SSJPLEN

Length of the IAZSSJP (SSJPSIZE) control block

SSJPVER

Input version of the IAZSSJP control block. Set to SSJPVER1 for version 1 of the control block or to SSJPVERC for the current version of the control block.

SSJPFREQ

Function to be performed on this request. Valid functions and their related SSJPUSER area are:

Field Value: Description
SSJPJCOD: IAZJPCLS Job Class Information service, obtain data
SSJPJCRS: IAZJPCLS Job Class Information service, release storage

SSJPUSER

Pointer to service specific data area '(IAZJPCLS)'

Set all other fields in the IAZSSJP control block to binary zeros before issuing the IEFSSREQ macro.

Job Class Information service, IAZJPCLS contents: For the Job Class Information service (function code SSJPJCOD), the caller must set the following fields in the IAZJPCLS control block:

Field Name: Description
JPCLID: Eyecatcher of the control block (set to 'JPCLASSD')
JPCLLEN: Length of the IAZJPCLS (JPCLSZE) control block
JPCLVER: Input version of the IAZJPCLS control block. Set to JPCLV010 for version 1 of the control block. Set to JPCLVER# for the current (latest) version
JPCLSTRP: Storage management anchor for use by the subsystem that responds to this request. It is expected that the caller will set this field to zero the first time IAZJPCLS is used and from that point on the field will be managed by the subsystem.

The caller can also set the following fields in the IAZJPCLS control block on input to limit (or select) which data will be returned.

Field Name

Description

JPCLFLG1

Flag byte which describes which filters to use to limit or select the data to be returned. Each bit corresponds to a filter that must be matched before data is returned.

Bit Value: Description
JPCL1CLS: Return job class information for those job classes that match the class name indicated by JPCLCNAM.
JPCL1GRP: Filters on a job class group.

JPCLGNAM

The group name to filter on.

Set all other fields in the IAZJPCLS control block to binary zeros before issuing the initial IEFSSREQ macro invocation.

For the Job Class Information service function code SSJPJCRS (release storage), the caller should not alter any fields in the IAZJPCLS control block returned on the last SSJPJCOD function call.
