Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM Common Data Provider for z * * Systems v2.1. * **************************************************************** * PROBLEM DESCRIPTION: HBO6114W message does not make sense, * * when Data Streamer heap is in high * * usage but only a little amount of * * sender data is discarded. * **************************************************************** * RECOMMENDATION: Apply this PTF. * **************************************************************** In some cases, the key contributor for the heap is not the sender. When this happens, only a little amount of data in the biggest sender will be discarded for GC (Garbage Collection) using the current logic. CDP needs to adjust the heap management to prevent this kind of invalid discard of data.
Problem conclusion
CDP v2.1 is updated to enhance the logic of heap management by adding a check of whether the sender is the key contributor of the heap or not, before discarding the data to enhance the GC efficiency of Data Streamer.
