Issue/Introduction

Issue:

This issue occurs on a customer Oracle RAC issue, the loginTimeout in TenantConfigurationManager.java is dropping all the connections when they take beyond 5 sec. On some environments this is causing an issue : errors are thrown in the logs, the database servers are unavailable, systems are in outage.

Error messages that can be seen in the logs:

ERROR 2016-02-22 02:25:01,376 [http-nio-7020-exec-149] filter.RequestTenantIdExtractor (none:none:none:none)

We also note random restarting of the affected services for app and bg.

1. On a system with a slower connections to the database, install CA PPM 14.3
2. Note that the database connections do not get created when they hit 5 sec
