The Vexcel Control Processor (COP) is a flexible, highly configurable distributed task scheduler. A central master controller and a relational database comprise the heart of the control processor. Remote Task Executor entities are in charge of executing tasks on the specified host and observe their execution and return value.
The master controller and the task executors are written in Java. They communicate via the socket-based Java Remote Method Invocation protocol. The database interface is built upon the Standard Query Language (SQL) foundation. It is kept as general as possible to allow different database products to be used interchangeably. Notably, SQLServer and Oracle are possible choices for the database server.
