Dynamic group definition
BMC ThruPut Manager
With BMC ThruPut Manager, DJC groups are defined dynamically by JECL statements inserted in the JCL of the jobs that are in the group. The group is defined by the first reference to it by a participating job.
IBM
In contrast, the IBM JEC group or network is predefined by a new construct called a JobGroup. The JobGroup is submitted as a block of JCL that defines the jobs that belong to the group (distinguished by a user chosen JobGroup name) and the dependencies amongst the jobs. The block of JCL containing the definition consists of JES2 Execution Control Statements.
The JCL for the jobs in the group contains a SCHEDULE statement which ties them to the JobGroup by name. The network definition is static and must be ‘registered’ before any of the jobs are submitted.
