Defining Log Streams and GDGs

This section describes the process of collecting and updating command flow data.

To get the latest command flow data, you should complete two basic tasks:
  1. Review and run the sample CIUJCDLS job that collects the data, and
  2. Review and run the sample CIUJCLCG job that defines the attributes for the command flow GDG dataset.

Both these tasks are covered in the sections that follow.

Before you start collecting data, consider the possible storage options for the CICS® IA log stream:
  1. Coupling facility, where log stream data is duplexed to a logger data space or staging data set. The coupling facility allows data from multiple CICS regions running on multiple z/OS® images to log command flow data to the same log stream
  2. DASD-only, where log stream data is duplexed in the MVS™ logger data space. The DASD-only option allows data from multiple CICS regions running on the same z/OS image to log command flow data to the same log stream
