System-Related Considerations

The following system-related issues must be considered when using the PIPE parameter in a Control-M job scheduling definition.

• Parallel processing changes resource usage in the system. All resources required for all the jobs in the Collection must be available when the jobs are submitted.

  This means that more resources, such as initiators, tape drives, CPUs, are required for shorter time periods; they become available after the jobs using the pipe finish execution. Therefore, when using pipes, resource usage in the system in which the jobs are to run must be reviewed to ensure that all required system resources are available at the time the jobs are submitted.

• The change in resource usage may necessitate changing the maximum quantities defined for Control-M to satisfy the changed requirements.
