The Initiator paramater in a JCL is used in the JCL Jobcard, for example, below the Initiator parm is CLASS=A.

//Job12345 JOB (acccode),'This is a JobCard',

//                 CLASS=A,MSGCLASS=X,MSGLEVEL=(1,1)

This enables a batch job to run in a TSO address space via a JES INITIATOR, in the example above, initiator class defined as A. 

JES initiators are configured by your systems programmers and can be either numeric or alpha - depending upon your site standards. 

Initiator 'classes' can also be defined to control resource allocations for different jobs running in different initiator classes i.e. jobs running in a particular class might have more resources i.e. CPU etc than those of a different class ~ this is site specific and your systems programmers should be able to tell you what the classes are and their differing priorities. 

Hope this helps?
