Caches and the Clear Cache Option

Caches and the Clear Cache Option

Informatica Data Director maintains a cache of MDM Hub metadata that describes base objects, columns, relationships, and other details. If you change the MDM Hub metadata, click
Clear Cache
in the IDD Configuration Manager before you export an application from IDD.
The Clear Cache option in the IDD Configuration Manager clears the cache for the selected IDD application. In a Microsoft SQL Server environment, Informatica recommends that you clear the cache when you make changes to the ORS metadata through the Hub Console. For example, if you add a relationship to a base object in the Hub Console and then save and validate the change, you can redeploy the IDD application for the change to take effect. However, you must clear the cache before you export the IDD application to see the new relationship in the Metadatabundle.properties file.
You can also restart the application server to clear the cache.
IDD also maintains caches of SAM role definitions and assignments and lookup values. IDD refreshes the caches at a rate that you can configure through IDD global properties.
