Input Parameters

Input parameters for the function routine are:

SSOB
SSIB
IAZSSJI
IAZJBCLD (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 71(SSOBSSJI)
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 on the life-of-job SSIB
SSOBINDV: Address of the function-dependent area (IAZSSJI control block)

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

SSIB Contents: If you don't 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 Job Information Services request is directed

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

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

Field Name

Description

SSJIID

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

SSJILEN

Length of the IAZSSJI (SSJISIZE) control block

SSJISVRN

Input version of the IAZSSJI control block. Set to SSJISVR# for version 1 of the control block

SSJIFREQ

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

Field Value: Description
SSJIFJCO: IAZJBCLD Job Class information service, obtain data
SSJIFJCR: IAZJBCLD Job Class information service, return storage

SSJIUSER

Pointer to service specific data area (IAZJBCLD)

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

Job Class Information service, IAZJBCLD contents: For the job class information service (function code SSJIFJCO) the caller must set the following fields in the IAZJBCLD control block:

Field Name

Description

JBCLSSID

Eyecatcher of the control block (set to 'JBCL')

JBCLLEN

Length of the IAZJBCLD (JBCLSZE) control block

JBCLSVRN

Input version of the IAZJBCLD control block. Set to JBCLSVR# for the current (latest) version.

JBCLSTRP

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 IAZJBCLD is used and from that point on the field will be managed by the subsystem.

JBCLFLAG

Flag byte

JBCL1JOB: Return a particular job class indicated by JBCLNAM

JBCLJNAM

Single job class to be returned.

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

For the Job Class information service function codes SSJIFJCR (return storage), the caller should set JBCLSTRP in the IAZJBCLD control block to indicate the storage to be released.
