The source HiRDB and the target Datareplicator use a data linkage file to report the extraction status. If an error occurs in the data linkage file or the data linkage file is initialized, conformity between the source and target databases might be compromised, because the data linkage preexisting at the source Datareplicator is lost. In such a case, you must re-create the target database. For details about how to re-create a target database, see 6.5.6 Source HiRDB handling procedure.

HiRDB checks the data linkage file when a synchronization point dump is collected. If the data linkage file has been initialized, the source HiRDB cancels HiRDB Datareplicator linkage and resumes its own processing at the source HiRDB.
