Hi All,

When im Trying to inserts segments into the database using a Cobol IMS program, the job is getting abended with following error message....

Can this be resolved by checkpoint logic??? If yes could you please let me know how to incorporate checkpoint restart logic in a cobol IMS program....

Code:
DFS0781I ABEND 0775 IN DFSECP20+S203+SP53+910+05/08/05PQ98461 A         IMSL

U0775
BMP program abended due to exceeding IMS calls between checkpoints.
Program has made too many calls without taking a checkpoint.

Could previous statements be the reason?

Thanks for the reply....yaa i guess soo....

If u could give me a sample logic of how to incorporate checkpoint logic in program that would be very helpful....

U775 - UNABLE TO AQUIRE A BLOCK OF STORAGE FOR QUEING CONTROL BLOCKS

since we do not know anything about Your system setup, we cannot tell
it might even be a gross mistake in defining the QCB pool characteristics

the best thing would be to ask You support and work with them for a solution
maybe just enlarging/adjusting the IRLM parameters could be enough

You cannot expect a forum to provide/teach what could be the object of an hefty consulting contract...

too many things to take into account, the programming part is just a low level technicality

Hello,

The "logic" is quite simple - just issue the checkpoint. . .

Having said that, the challange arises deciding when/where to issue the checkpoints. Checkpoints ar mostly to mark the end of a logical unit of work and ensure they are committed to the database (ie - a subsequent data error or program abend will not "undo" them). If you choose to checkpoint within a process, you also need to know how to restart/rerun the prcess. Which should be decided by your organization, not implemented for a single program.

Also, performing the CHKP call will make you lose position in all of your databases. So if you are walking a database and using it as your driver, you have to save that key, take the checkpoint, then do a GU call to get back to that key in the DB.

To see how your shop handles this, I'd suggest you do a scan on the source library for "CHKP". Then study that program a little bit to see how your shop's standards are implemented.
