Deprecated and discontinued configuration parameters
Due to changes in related functionality, the introduction of new functionality, or the removal of support, some Informix® configuration parameters that are available in earlier releases are either deprecated or discontinued. Review the summary of the changes to understand the overall impact on your environment.
- Deprecated configuration parameters
- During migration be aware of the configuration parameters that are deprecated. Support for these configuration parameters might be removed in a later release. Avoid creating new dependencies that rely on these configuration parameters, and if you have existing dependencies on them, develop plans to remove these dependencies.
- Discontinued configuration parameters
- If you are migrating, be aware of the functions that are no longer supported.
