PTF SA89838 for Domino R5.04 is a Domino for AS/400 hotfix that is now available and is known to improve the performance of certain applications using LotusScript. In particular, this improvement has been seen in Domino.doc, as well as that of the ezMerchant product from Binary Tree. It improves performance of large LotusScript agents in Domino applications by disabling a run-time check for duplicate names. This check is unnecessary in most instances, as duplicate name problems should have been debugged when the agents were developed. If you wish to turn this check back on to investigate problems with agents that are not executing properly, you can set the variable "LS_Dup_Name_Check=1" in notes.ini and recycle the task that is running the agents (or just recycle the entire server).This fix will be included in the 5.0.4a QMU.
