They are completely different entities. Environment variables are UNIX (and Windows) constructs that are used for user and OS information to be stored and used; i.e. for keeping information on what PATHs to use for programs and libraries and for storing program settings such as the ORACLE or DB2 version. These environment settings can, and often are, passed on when a process is forked and are also kept when one process calls a program or procedure
Job Parameters are variables that need to be declared on both the calling and job side and are used to pass specific runtime values to a job.
