Abstract

A computerized method is provided for managing replicated database resources. Systems and methods described can use a plurality of geographically distributed servers to query a replicated database and determine the databases health based on monitored golden signals in response to the query. The various servers can be geographically distributed and can report their database health findings to a monitoring agent which can use quorum logic based on all of the reporting servers to identify resource health and trigger failover to another instance of the replicated database when warranted. Such systems and methods can thereby detect not only hard failures but also so-called grey failures resulting in diminished resource performance and trigger failovers to increase resource performance.

Claims20

Dependent claims

A computerized method for managing replicated database resources, the method comprising:

querying a first instance of a replicated database with a plurality of global service manager (GSM) servers;
receiving, at each GSM server, a plurality of golden signals from the first instance of the replicated database in response to the query;
at each the plurality of GSM servers, separately determining database health for the first instance of the replicated database based on the received plurality of golden signals, wherein the database health comprises an indication of healthy or unhealthy and wherein one or more of the plurality of golden signals received by one of the plurality of GSM servers exceeding a threshold causes that GSM to provide an indication of unhealthy;
receiving, at a monitoring agent, the database health indication from each of the plurality of GSM servers;
comparing, at the monitoring agent, the database health indication received from each of the plurality of GSM servers;
and
triggering a failover switch to a second instance of the replicated database when a number of database health indications of unhealthy received from the plurality of GSM servers exceeds a threshold.

A computer system for managing replicated database resources, the system comprising a processor in communication with a non-transient memory and operable to perform the steps of:

querying a first instance of a replicated database with a plurality of global service manager (GSM) servers;
receiving, at each GSM server, a plurality of golden signals from the first instance of the replicated database in response to the query
at each the plurality of GSM servers, separately determining database health for the first instance of the replicated database based on the received plurality of golden signals, wherein the database health comprises an indication of healthy or unhealthy and wherein one or more of the plurality of golden signals received by one of the plurality of GSM servers exceeding a threshold causes that GSM to provide an indication of unhealthy
receiving, at a monitoring agent, the database health indication from each of the plurality of GSM servers;
comparing, at the monitoring agent, the database health indication received from each of the plurality of GSM servers;
and
triggering a failover switch to a second instance of the replicated database when a number of database health indications of unhealthy received from the plurality of GSM servers exceeds a threshold.
