I have two jobs running almost at the same time. Both of them access and update the same Adabas files. These two jobs have a successful completion code most of the times. But at times one job fails with an “Invalid CID value” error. When its rerun without any modifications it runs successfully.
I dont understand the meaning of this error. I think its because of parallel updates to the database. Kindly let me know the reason of this error. Also, please throw some light on the locking mechanisms and parallel updates in Adabas.
Thanks for the help.
