E1: KER: What Is the Recommendation for 500+ Concurrent Users per Enterprise Server in EnterpriseOne? (Doc ID 2656004.1)

Last updated on JULY 26, 2021

Applies to:

JD Edwards EnterpriseOne Tools - Version 9.1 and later
Information in this document applies to any platform.


Oracle recommends for EnterpriseOne customers to have no more than 500 concurrent users using any single enterprise server instance.  Following this recommendation will reduce the contention among enterprise server processes for IPC mutex locks within a single instance.

The contention for mutex locks is particularly high among multiple metadata kernels and UBE batch processes.  This is because the metadata kernels spend much of their time using mutex locks to build sets of TAM files under the spec/RunTimeCache folder while the other kernels and batch processes are waiting for these mutex locks.  The greater the number of metadata kernels, the greater the contention among them for mutex locks for accessing the shared files in the RunTimeCache folders.


The contention for mutex locks is also high for JDENET message data transfer across multiple network, kernel and batch processes which uses IPC Blob when the message data size is larger than the value defined in maxLenFixedData attribute under [JDENET] section in JDE.INI.
