Calling REST API on a clustered system fails randomly

(Doc ID 2069797.1)

Last updated on NOVEMBER 03, 2016

Applies to:

Oracle WebCenter Sites - Version 7.6.2 and later
Information in this document applies to any platform.

Symptoms

Some custom code calls a Sites REST API to retrieve data. When called successive times with the same parameters, sometimes if fails with an "invalid ticket" error, and sometimes it succeeds.
This is a clustered system, all access (including REST API) is via a loadbalancer. When testing with only one node enabled, tests are consistently successful.
