Overview

Last Updated : Dec 20, 2022 |

Avaya Analytics™ disaster recovery provides a planned approach to re-establish critical services at a secondary data center when a complete outage occurs at the primary data center.

This section provides information on how to configure a geographically redundant Avaya Oceana®, so that when a primary data center outage occurs, the redundant site can be made operational.

In this configuration, two instances of Avaya Analytics™ are deployed in two separate data centers with Write Ahead Log (WAL) streaming between the operational reporting databases. With WAL streaming, the primary data center database continuously streams updates to the secondary data center.

Avaya Analytics™ also provides support for disaster recovery scenarios where you might lose the primary DB node in DC1 for an extended period of time and you want to configure your DC2 system to stream from the failed over replica node on DC1 instead of the default primary node.

Analytics Geo Enhancements

The Analytics Geo solution is enhanced for Historical Reporting so that the custom reports and local users in the metadata are replicated from a primary DC to a secondary DC.

  • Replication of Historical Reporting Local users in metadata to DC2.

  • Replication of Historical Reporting custom reports in metadata to DC2.

    Note:

    In this configuration where two instances of Avaya Analytics™ are deployed the Historical Reporting Administrator credentials must be identical as this is replicated between both DC1 and DC2.

Warning:

If Geo Primary performs a full backup during a network outage and Geo Standby cannot access the NFS server on Geo Primary, Geo Standby loses the WAL archive sequence to catch up after the network outage is resolved.

Losing the WAL archive sequence to catch up causes the Geo alarm to trigger as the last update received on Standby exceeds the time limit.

Consequently, it is necessary to run the CCM analytics script on Geo Standby to recreate the standby system based on the new backup and WAL archives.
