Just like we have checkpoint in BMP , do we similarly have syncpoint for MPP. What is the difference ? Can you provide me any link to a good document

Thanks

What exactly you wanted to do in MPP?

There is no syncpoint keyword in IMS.

If you want to store the database updates, you can issue TERM call.

Syncpoint is a kind of taking backup before running any updation jobs....Checkpont is used in ims programs to commit the changes for regular intervals...

For MPP's one doesn't program CHKP-calls. The ENTER button hit on the keyboard makes IMS take checkpoints automatically.

When you do a checkpoint, you control that within your application program. Your tech services - IMS systems programmers will help. Syncpoints in MPP programs are normally set by your tech services group - your systems programmers. You normally should not really have no control over your syncpoints in an online application program.
