Oracle Virtual Desktop Infrastructure 3.4 Shows "High Availability Not Enabled" (Doc ID 1503742.1)

Last updated on MAY 05, 2021

Applies to:

Oracle Virtual Desktop Infrastructure - Version 3.4 and later
Information in this document applies to any platform.

Symptoms

Oracle Virtual Desktop Infrastructure features a HighAvailability mode for its underlying MySQL database engine.  This feature is based upon two servers being available to run MySQL so that, should one fail, the remaining server can provide MySQL functionality.  When only one of the two servers is functional a backup is no longer available and the High Availability feature is temporarily disabled.  This can be seen in messages like those below in the Cacao logs where the Master server is functional but the Slave is not functional.

 

Changes

The /etc/hosts files on the two servers might have been changed so that the address of one server is listed as belonging to the other server.
