Data Model Cache

The Data Model Cache page displays all the Data Model Caches created in the Wyn application in the Resource Portal.

A user can perform the following activities using the Data Model Cache page:

  • View all the Data Model Caches along with their status

  • Rebuild the invalid Data Model Cache manually when the cache model cannot be edited or reloaded

  • Search the specific Data Model Cache

  • Sort Data Model Cache by Name

  • View status information and last error message

  • Option to search for only the Failed Data Model Cache

View Data Model Cache

  1. On the Admin Portal, navigate to System Management > Data Model Cache Status.

    Data Model Cache Status page is displayed with all the Data Model Caches created in the Wyn application.


    To view only the failed cache models select the checkbox Only show failed data model cache at the top next to the search box. The failed cache models include Invalid Data Model Cache and Data Model Cache with Warnings. You can rebuild these failed data model caches by clicking the Rebuild Cache button.

    Note: The Data Model Cache Status page supports pagination. Documents are listed page-wise, so it helps in terms of overall navigation and the process of listing the documents is also faster. You can specify the number of documents to be displayed per page from the drop-down list. Like here, we have selected 20 documents per page. If you want to go to a particular page, you can enter the page number in Go to and press Enter or click the page number, or you can use the Next Page/Previous Page arrows. This feature is available from Wyn 7.0 onwards.

    Cache Model Status

    Cache status of the model depends on the cache status of the entities it contain.

    • Entity cache status in the cache model has three types: Available, Unavailable, and Available(previous data version).

    • Each model may contain multiple entities, so due to the three status types of the entity, the model may have the following situations and the model cache will show three status types:

    Cache Model Status

    Cache Model Entities Status





    Available, Unavailable

    Unavailable, Available(Previous Data Version)

    Available, Unavailable, Available(Previous Data Version)


    Available, Available(Previous Data Version)

    Available(Previous Data Version)
