Deleted records

 

On the iSeries™ server, a record is marked as deleted by the server.

This is done either when an active record is deleted by an application or when a file is created with deleted records (for example, with the Initialize Physical File Member (INZPFM) command). A record that is added to a file or changed in a file is never marked as deleted, unless a subsequent delete operation is performed. On some other servers, like the System/36™, a special data value in the record might be used to indicate deleted status. For example, if a record contains all hex FFs, it might be considered deleted.

This means that an iSeries application normally used to add or change records in a local file might encounter errors when attempting these operations with a remote file on a server that is neither an iSeries server nor a System/38™. If the application happens to supply a record that is considered deleted by the target DDM server, the target might reject the add-or-change request.
