Hello there!

I would like to ask what syncpoint command does in the pgm?. Is this really help to release the resources?
E.g. System 1(Screen1) do a tranx, then System 2 (screen2) is also doing a tranx, then screen 2 abended with error SQL 911 (contention with Screen1).
Screen1 calls a program that updates the file (FILE1) w/c Screen2 also using.
With this, they told me to use the SYNPOINT command in screen 1 as per their explanation this is not to hold FILE1 too long (to release FILE1) so that other screens can access the FILE1.
Thanks!

syncpoint is similar to commit.

if you update a record then it will held until you issue syncpoint or end of transaction.

if you issue syncpoint rollback. your updates will be cancelled.
