We upgraded our mainframe Adabas from 744 to 814 and encountered the error: Adabas response code 240 when executing Native SQL statement EXEC Adabas. The error refers : ATM encountered an error. There is no sub code to this error. We have never used Adabas Transaction Manager in this environment.
Has anyone experienced this error before? We had to backout the upgrade as critical applications were failing with the error.
