E1: JAS: Submitting UBEs from Web Client Causes JDBC Connection Leaks

(Doc ID 1471819.1)

Last updated on MAY 30, 2017

Applies to:

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

Symptoms

EnterpriseOne is unresponsive or unstable after submitting several UBEs from HTML/Web clients in a short period of time (under 2 min). Monitoring the JDBC connection pool size from Server Manager Console shows that the pool is reaching its maximum size when the symptoms start.

Analyzing debug logs, it is possible to see how some of the connections generated by the UBE submission are only checked in after they are timed out:

Changes

This is a new installation on EnterpriseOne 9.1 with Tools Release 9.1.0.3, but the same behavior is seen with TR 9.1.0.2.

In this case, there are high performing Solid State Disks (SSD) which allows users to submit several reports in a few seconds from the HTML/Web clients.
