Error description

  • While testing and preparing to upgrade from 9.4.1 FP3 to 10.1
    FP1...?Despite seeing some clear improvement in concurrency with
    Parallel Interaction enabled, which they have designed some key
    processes to take advantage of, they have isolated a couple
    problems/concerns:?- Performance of a process to push data from
    a number of cubes to a reporting cube is approximately 2 times
    slower with Parallel Interaction enabled than the current 9.41
    FP3 production version?- They are observing situation where they
    see improvements in the time to load a large number of values to
    a cube from a flat file (which is what this data push process
    uses) when they remove other, what they are certain are
    unrelated, cubes from the TM1 Server (which doesn't make much
    sense)
    

Local fix

  • There are ongoing efforts to improve this performance in upcomin
    g releases. In the meantime, a workaround that could provide som
    e improvement to the performance (to alleviate some of the time
    establishing and evaluating dependencies) would be to utilize th
    e BatchUpdate function in your TI Process(es). Should you decide
     to implement this workaround, please open a PMR with support re
    ferencing this APAR to evaluate, review, and quantify the improv
    ement from this change so this APAR may be updated with addition
    al information.
