Monitoring data-sharing systems

To monitor data sharing, you obtain information on the status of the following: IRLM, IMS systems and databases, the RECON data set, and coupling facility structures.

Obtaining the status of IRLM activity
Use the MODIFY z/OS command to display the status of an IRLM.
Displaying components and resources
Monitoring components and resources in a data-sharing environment requires the same kinds of procedures as in a non-sharing environment.
Monitoring information in the RECON data set
Evaluate information from the RECON data set on a daily basis to understand the status of the total data-sharing workload and response times for all critical data-sharing transactions.
Monitoring structures on a coupling facility
The DISPLAY XCF,STRUCTURE and DISPLAY XCF,STRUCTURE,STRNAME=z/OS operator commands are especially useful in monitoring structure activity.
