CICS have special future for data Base updates i.e. TWO FACE COMMIT. On completion of CICS program, syncpoint will execute which will commit the changes from CICS end and request for DB2 Commit.

For this question, here there is no explicit DB2 Commit request and the CICS not completed. So the changes will rollback.
