Reducing application downtime during failover
First Claim
1. A system for reducing application downtime during failover, the system comprising a computer processor and a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that when executed by the computer processor cause the system to carry out the steps of:
- identifying a critical line in the startup of an application, the critical line comprising the point in the startup of the application in which the application begins to use dependent resources;
checkpointing the application at the critical line of startup;
identifying a failure in the application; and
restarting the application from the checkpointed application at the critical line.
