HASH Based Change Detection errors JDBC connector RRS feed

  • Question

  • Hi,

    I have configured FAST to crawl MS SQL databases using JDBC connector.

    I have enabled change detection using HASH and i receive lots of errors. there are 3 million items to be crawled (SQL). Many items does not appear in Fast Collection because of these error.

    What could be wrong? May be it is better to use TIMESTAMP based detection?

    errors:

    09:54:03,519 ERROR [ChangeDetectorSQLServer] Could not register success operation for docid:00319E-R3010ALTfr-FR - msg - null
    09:54:03,535 ERROR [CCTKCallbackHandler] Error when registering callback in checksum database for document:00319E-R3010ALTfr-FR
