You can operate BTS in a single CICS® region. However, BTS processes are sysplex-enabled. In a sysplex, you can create one or more BTS-sets. A BTS-set is a set of CICS regions across which related BTS processes and activities may execute. For example, the activities that constitute a single process may execute on several regions.
In a BTS-set, the CICS transactions that implement your BTS activities can be routed dynamically across the participating regions. When an event is signalled, an activity is activated in the most appropriate region in the BTS-set, based on one or more of the following:
You can control the dynamic routing of your BTS activities by either of the following means:
Dynamic routing of BTS activities is described in Using BTS in a sysplex.
You can create an audit trail for the BTS processes and activities that run in your CICS regions. Doing so allows you to, for example, track the progress of a complex business transaction across the sysplex.
The CICS code contains BTS audit points in much the same way as it contains trace points. However, because in a sysplex environment different parts of a process may execute on different regions, each audit record contains system, date, and time information. By sharing log streams across regions, you can gather audit information from different regions in the same log.
