Abstract
A native Job Control Language (JCL) execution engine is provided in a mainframe rehosting platform/open platform for executing a migrated JCL job without converting the JCL job to another language. The JCL execution engine provides a framework which supports an internal JCL mechanism, a simulation of a plurality of mainframe utilities commonly used in JCL jobs, and a simulation of commonly used database utilities. When the JCL execution engine receives a JCL job, it generates a statement sequence from the JCL job, orders statements in the sequence into a doubly-linked sequence, and parses the doubly-linked sequence to construct a job element hierarchy tree for execution. A plurality of job initiators are provided to dequeue jobs from a job queue and dispatch the jobs to the JCL execution engine or another type of execution engine.
