Analytics Causing Performance Slowdown with Async Property Bug (Doc ID 2041720.1)

Last updated on JUNE 01, 2017

Applies to:

Oracle Knowledge - Version 8.5.0.2 to 8.5.1 [Release 8.5]
Information in this document applies to any platform.
Oracle Knowledge Analytics can be run with asynchronous or synchronous logging. Synchronous logging would wait for a response from the JMS queue each time it writes analytic information and Asynchronous logging is faster because it does not wait for a response from the JMS queue.

Asynchronous logging should have a 10 percent performance cost on the product, but synchronous logging can have 100 to 150 percent cost depending on the speed and location of the jms queue.

Symptoms

Oracle Knowledge performance could be running slower than expected if Analytics JMS queue function is writing Analytics to the JMS queue synchronously.

Changes

The ok.async.logging=true property needs to have extra spaces removed.
