How can I implement checkpoint restart logic in DB2. The one similar in IMS?
I have an issue here - A Job that is doing database update got failed. But while restarting, I have given wrong GDG base and it has updated with yesterday's data. Luckely I have found it while checking the data.
Can someone help me to fix this? I need the Job to be abended if we use a wrong input file(GDG/Flat).
I dont have much experience in DB2. Can someone please help me?
