APAR status

  • Closed as program error.

Error description

  • For decision services with a large number of rules
    (about 50k rules), applying the actions of a query perform very
    poorly if setting "teamserver.build.elementOnCommit" is true
    for the projects of the DS.
    

Local fix

  • The "build on-commit" project option should be turned off for
    all projects of the Decision Service.
    Actually this option should better be off in all cases. This
    way the IRL gets generated when building the rulesets, then
    other optimizations can be used in order to handle several
    rules in a single operation.
