E1: UBE: KER: UBEs and Business Functions Running Slow on AS400 (IBM I series) Platforms After Upgrading Tools Release to 9.2.3.3 or 9.2.3.4 or 9.2.3.5 (Doc ID 2600839.1)

Last updated on APRIL 01, 2020

Applies to:

JD Edwards EnterpriseOne Tools - Version 9.2 to 9.2 [Release 9.2]
Microsoft Windows (32-bit)
Microsoft Windows x64 (64-bit)
IBM i on POWER Systems

Symptoms

After upgrading the tools release to 9.2.3.3, 9.2.3.4 OR 9.2.3.5, UBEs take longer time to complete and are processing considerably slower as compared to previous tools release. Significant performance decrease may also be observed in business function processing (Call Object Kernels), especially large running business functions. 

Performance impact is more noticeable on platforms where Non-Unicode datasources are still in place. Non-Unicode datasources are known factors for slow running UBEs, and this issue manifests as a further decrease in performance of UBEs or business functions on such systems.

This issue has following characteristics which may distinguish it from other performance issues on UBEs and Business functions;

  1. There is no performance impact on UNIX, LINUX and SOLARIS platforms.
  2. The performance impact is more noticeable where large datasets from multiple tables are involved.
  3. The performance impact is observed despite SQL queries returning results in timely fashion. Any slowness or performance degradation due to long running SQL queries as observed during log analysis, must be considered as a different issue which requires further analysis.
  4. Slowness is observed despite fast network and communication channels. Any slowness or performance degradation due to network latency must be considered as a different issue which requires further analysis.
  5. While IBM-I (AS400 I-SERIES ) platforms are known to be impacted significantly w.r.t. to UBEs, the impact on windows platform is not observed to be very high so far . Hence, if a significant and very high performance degradation is being observed for UBES and Business functions running on WINDOWS platforms, then it is possible that additional issues exist in system which requires further analysis.
