A rule to determine how many batches can run simultaneously is that the combined number of parallel streams should keep the CPU 100 percent busy. These can either be multiple EIM processes running simultaneously, or the same EIM process repeated against multiple partitions of the same table.
If you run EIM processes in parallel on a DB2 database with the default setting of
A similar problem might occur if parallel processes access the same child tables while updating foreign keys. Therefore, analyze your EIM mappings and processes, and do not run these processes in parallel. Alternatively, you can try altering the locking level from Page to Row.
