Performance tuning

Performance can be affected by many factors. The following information is related to map execution and may improve performance.

• Reduce the size of the structure validation file.

  Review Card 7: structure detail file.

• With z/os processing, suppress the run map log.

  Review Card 8: system information file.

• Skip the initial compliance processing step with SkipTTValidation setting.

  Review the Configuration information details section.

• Workspace and page overrides.

  Review the Configuration information details section and the following information.

The best configuration settings for the map RUN calls for the schema validation map, and the segment validation map, depend on the size of the transactions to be processed by the compliance check maps. The default setting uses work files that are in memory, and is best for small to medium size transactions. The transaction size at which performance improves by using a work file on disk, depends upon the amount of memory available after other applications and services are taken into account.

The recent compliance check maps use the setting in the configuration files without map modifications. You can review the WorkSpace configuration setting. However, older versions of the compliance check maps may not be using the configuration setting. Therefore, it may require the following map modifications.
