   2021-03-23 07:23:12,608| ERROR | main | com.castsoftware.adg.webservice.dao.portfolio.TechnologyDao | Skip snapshot [name:'rct4-common', date:'Mon Mar 15 14:17:00 CDT 2021', id:'17220'], because of inconsistent technological object [id:'

   1. Run the below query on central to check the corruption related to technological objects :

      SELECT DISTINCT doi.snapshot_id,
                      doi.object_id,
                      doi.object_type_id,
                      dot.object_type_name AS OBJECT_NAME,
                      'Technologic '
                      || dot.object_type_name
                      || ' object'        AS OBJECT_DESCRIPTION,
                      dot.object_type_name AS OBJECT_FULL_NAME
      FROM  dss_link_info dli
            JOIN dss_object_info doi
              ON doi.snapshot_id = dli.snapshot_id
                  AND doi.object_id = dli.next_object_id
            JOIN dss_object_types dot
              ON dot.object_type_id = doi.object_type_id
            LEFT JOIN dss_objects dos
                    ON dos.object_id = dli.next_object_id
      WHERE  dli.link_type_id = 2
            AND dos.object_id IS NULL
      

   2. ]If the query returns result then run the below query to fix the corruption in central :

      insert into DSS_OBJECTS (OBJECT_ID, OBJECT_TYPE_ID, OBJECT_NAME, OBJECT_DESCRIPTION, OBJECT_FULL_NAME)
      select distinct doi.OBJECT_ID, doi.OBJECT_TYPE_ID, dot.OBJECT_TYPE_NAME as OBJECT_NAME,
      'Technologic ' || dot.OBJECT_TYPE_NAME || ' object' as OBJECT_DESCRIPTION, dot.OBJECT_TYPE_NAME as OBJECT_FULL_NAME
      from DSS_LINK_INFO dli
      join DSS_OBJECT_INFO doi
      on doi.SNAPSHOT_ID = dli.SNAPSHOT_ID and doi.OBJECT_ID = dli.NEXT_OBJECT_ID
      join DSS_OBJECT_TYPES dot
      on dot.OBJECT_TYPE_ID = doi.OBJECT_TYPE_ID
      left join DSS_OBJECTS dos
      on dos.OBJECT_ID = dli.NEXT_OBJECT_ID
      where dli.LINK_TYPE_ID = 2 and dos.OBJECT_ID is null

   3. Once done, consolidate the central to measurement schema.
