Use the CA XCOM Data Transport Health Checks to Tune the CA XCOM Data Transport Regions

The IBM Health Checker for z/OS allows you to identify potential problems in your z/OS environment by checking system or product parameters and system status against recommended settings. The IBM Health Checker for z/OS is structured as a framework that includes a health check started task and various separate check routines provided by IBM or other vendors. CA XCOM Data Transport provides health checks for virtual storage usage (above and below the line) as well as task-level monitoring. When exception conditions are found, the CA XCOM Data Transport health checks provide detailed recommendations on how to correct the problem. The CA XCOM Data Transport health checks also make best practice recommendations for using CA XCOM Data Transport.

These health checks are automatically activated when the CA XCOM Data Transport region is started if the following components are configured and running on your system:

• IBM Health Checker for z/OS—This free component is distributed with every supported level of z/OS. If you have not yet set up this component, see the IBM Health Checker for z/OS User Guide for details on how to set it up.
• CA Health Checker Common Service—a free CA Common Services component. The load library for this component must be authorized and installed in the link list on the target system where the CA XCOM Data Transport health checks will be run. A new address space is not required for the CA Health Checker Common Service. For the CA Common Services release levels that support this functionality, see http://support.ca.com.
