FABSPSSI PSSRIN data set

The PSSRIN control data set contains your specifications for a user exit, a DATXEXIT and data compression of *CS format for PSSR.

These specifications are effective when PSSR runs in the IMS™ environment.

Subsections:

USEREXIT control statement
DATXEXIT control statement
COMPRESSED control statement

Format

PSSRIN usually resides in the input stream. However, it can be defined either as a sequential data set or as a member of a partitioned data set. It must contain exactly one 80-byte fixed-length record. BLKSIZE, if coded, must be a multiple of 80. The PSSRIN data set can be coded as follows:

 //PSSRIN    DD  *
  USEREXIT=UEXPGMA,L
  DATXEXIT=YES
  COMPRESSED=YES
 /*

USEREXIT control statement

Specifies whether PSSR invokes a user exit routine.

This control statement is optional. If you do not specify this control statement, no user exit routine is invoked.


>>-USEREXIT=--exitname--+----+---------------------------------><
                        '-,L-'

exitname: The name of a user exit routine. Specify this operand if you use the exit interface of PSSR. The specified exit routine must reside in the IMS2 DD data set.
L: Specify this operand only if the user exit routine is to be run under an environment of LE (Language Environment®). This option is effective when the user exit routine is written in Enterprise COBOL for z/OS® or Enterprise PL/I for z/OS. This option is not effective for Assembler.

DATXEXIT control statement

Specifies whether PSSR invokes a data conversion exit routine.

This control statement is optional. If you do not specify this control statement, PSSR does not activate the data conversion exit.


              .-NO--.   
>>-DATXEXIT=--+-YES-+------------------------------------------><

YES: Activates the data conversion exit.
NO: Deactivates the data conversion exit.

The conjunction of the DATXEXIT using of unload utilities of IMS High Performance Unload, PSSR, and IMS HP Load must be one of the following:

Reorganization in the stored form: Specify NO for all three jobs.
Reorganization in the application view form: Specify YES for all three jobs.

COMPRESSED control statement

Specifies whether the input unloaded records in the *CS format are to be compressed by a segment edit/compression exit or not.

This control statement is optional. If you do not specify this control statement, COMPRESSED=YES is used.

This control statement is effective only when all of the following conditions are met:

The format of the unloaded database data set is *CS.
The data compression is specified in the DBD.
The DBD is defined as non-HALDB.

If the listed conditions do not apply, then this statement is ignored.


                .-YES-.   
>>-COMPRESSED=--+-NO--+----------------------------------------><

YES: Specifies that the input unloaded data set is in the *CS format and the data is compressed. PSSR assumes the input unloaded records as compressed.
NO: Specifies that the input unloaded data set is the *CS format and the data is not compressed.
