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:
- Review and run the sample CIUJCDLS job that collects the data,
and
- 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:
- 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
- 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
