Multiple Scheduler Instances

Support for storing task data in networked databases allows multiple instances of the Scheduler service to run at the same time, on multiple servers, creating a fault-tolerant configuration. If one of the Scheduler instances goes down, the remaining instances will continue to function. Having multiple Scheduler service instances will not result in a task being run more often than its designated frequency. The Scheduler service can be installed independently of the full Logi Info product.

A multi-instance configuration is not supported when using the standard embedded VistaDB (.NET) or Derby (Java) databases.

For the purposes of interacting with multiple Scheduler service instances from a Logi application, the application's _Settings definition must be properly configured to address all of the instances. This is discussed in Using Logi Scheduler.
