System Extensions (SARXTD)

The product has been designed to function without any modifications to operating system code. However, some features are so closely tied to the operating system that they could not be implemented if the policy of no system modifications were strictly adhered to. These features are available through CA View system extensions.

To implement a system extensions feature, CA View "front ends" the appropriate operating system function by dynamically interfacing to the running system (for example, changing an address in the SVC table). Because the change is dynamic, no permanent change is ever made to operating system code. Choosing to implement the features in this manner has two major benefits:

• The features can be activated or deactivated when required.
• CA View does not affect the operating system maintenance.

Currently, only three features require implementation using system extensions:

• Security of CA View data sets
• Automatic report archival
• Capture of job accounting data

If you require any of these features, activate system extensions on each processor at your site.

The system extension task is not a continuously running task and only executes long enough to interface dynamically to the system; then it terminates.

If the data set security feature of system extensions restricts access to the CA View LOAD library, the CA View LOAD library cannot be used in a STEPLIB or JOBLIB DD statement of any executable job.

You cannot use the CHKPT macro or the CHKPT=EOV JCL statement with SARXTD alone. Use them with CA Deliver.

Note: For more information about archival, see Automatic Report Archival in the chapter "Archival."
