Answer Posted / sampath
Checkpoint Code:
CALL ‘CBLTDLI’
USING FUNC-CODE,
I/O PCB,
I/O AREA,
(CHKPT-DCB)
FUNC-CODE : ‘CHKP’
I-O PCB : Real or dummy
Returns status code
I-O Area: 8 byte CHKPT ID going out should be alphanumeric
in a BMP or MPP
Will return a segment that will permit the system to
shutdown
CHKPT-DCB : This is optional. If specified it goes to OS/VS
check point. It is needed to checkpoint non-IMS resources
or to restart program at other than entry point.
Restart:
Works with extended restart (XRST) call to restart your
program
Can save as many as 7 data areas in your program, which are
restored when your program is restarted
CALL ‘CBLTDLI’ USING FUNC-CODE
I/O PCB, I/O AREA LEN, I/O AREA,
1ST AREA LEN, 1ST AREA,
[…,…, 7TH AREA LEN, 7TH AREA]
Used to restart a program after abnormal termination
Restart from
Specific checkpoint ID
Date/Timestamp (YYDD/HHMMSS)
Last checkpoint
Issue it once as the first call in the program
Call format similar to symbolic checkpoint call
