Setting up CICS data sharing servers

To initialize CICS® data sharing servers, you must set up AXM system services and define appropriate data sharing servers. You must also ensure that AXM and any data sharing server address spaces being used are started before the CICS regions try to use them.

CICS data sharing servers support the following functions:

Temporary storage data sharing
Coupling facility data tables
Named counters

Note:

Users implementing CICSPlex® SM sysplex optimized workload management will require a region status server to be configured. This server is a bespoke type of CFDT server into which CICS regions broadcast generic system status data which is subsequently interrogated by CICSPlex SM for making dynamic routing decisions. The table structure managed by this server may not be modified, adjusted, or reconfigured for user application utilization.
