Abstract: Provided are a computer program product, system, and method for maintaining metadata from a catalog in a repository to return to requests for the metadata. A first instance of a request for metadata from a catalog of metadata on data sets is intercepted from an application and the metadata is retrieved from the catalog and saved in a repository. The retrieved metadata is associated with the request in the repository. The metadata retrieved from the catalog is returned to the application for the first instance of the request. A second instance of the request is intercepted from the application. A determination is made whether to fulfill the second instance of the request from the repository. The metadata for the second instance of the request is retrieved from the repository in response to determining to fulfill the second instance of the request from the repository.

Abstract: A method can include obtaining catalog data of a catalog. The catalog can include one or more records. The method can further include detecting one or more damaged records among the one or more records and isolating the one or more damaged records. The method can further include identifying one or more undamaged records among the one or more records. The method can further include transferring the one or more undamaged records to a backup catalog. The method can further include obtaining a transfer status of a first undamaged record of the one or more undamaged records. The method can further include obtaining an access request corresponding to the first undamaged record. The method can further include determining, based on the transfer status, a response to the access request and generating, based at least in part on the backup catalog, a restored catalog.
