High Availability Check
Introduction
The High Availability Check!! monitors two Anywhere365 Application Servers and automatically starts the Unified Contact Center services on the passive server if the UCC A Unified Contact Center, or UCC, is a queue of interactions (voice, email, IM, etc.) that are handled by Agents. Each UCC has its own settings, IVR menus and Agents. Agents can belong to one or several UCCs and can have multiple skills (competencies). A UCC can be visualized as a contact center “micro service”. Customers can utilize one UCC (e.g. a global helpdesk), a few UCC’s (e.g. for each department or regional office) or hundreds of UCC’s (e.g. for each bed at a hospital). They are interconnected and can all be managed from one central location. service is no longer running on the active server. Optionally, an email can be sent if one of the two servers is taking over the role of active Anywhere365 Application Server.
Limitations
The High Availability Check!! only works when both Anywhere365 Application Servers are installed in a single Lync Microsoft Lync (formerly Microsoft Office Communicator) is an instant messaging program designed for business use and is the successor of Windows Messenger. In order to use Lync, a Microsoft Lync Server is required./Skype for- Business Trusted Application Pool. If the Anywhere365 Application Servers are installed in separate Skype-for-Business Trusted Application Pools the Disaster Recovery Scenario should be followed instead. Also, the script will only work if both Anywhere365 Application Servers can be pinged. If this is not the case the script stops, and optionally sends an email to notify that the Anywhere365 Application Servers cannot be pinged and network connectivity should be checked. Finally, make sure the Recovery options for the Unified Contact Center service on both the active and the passive Anywhere365 Application Server are turned off.
Scenario 1 Lowest Footprint
In this scenario the passive Anywhere365 Application Server monitors the active Application Server. As soon as the passive Anywhere365 Application Server detects the Unified Contact Center service on the active Application Server is not running it will take over. From this moment on, the former active Anywhere365 Application Server, will become passive, and starts monitoring the former passive Application Server.
Scenario 2: Using a Witness
In this scenario, there is a third server, that is not an A365 Application Server. This so-called Witness Server, monitors both the active A365 Application Server as well as the passive A365 Application Server. The benefit of this scenario is that network connectivity will not interfere with the decision to take over the Unified Contact Center service from the active to the passive server. As soon as the Witness Server detects the Unified Contact Center service on the active A365 Application Server is not running it will start the service on the passive A365 Application Server and vice versa.
