When running Load Data Warehouse, an error is thrown in the bg-dwh.log:
An error occurred executing SQL: SELECT CASE WHEN a.record_count > 0 THEN 1 ELSE 0 END record_exists FROM (SELECT COUNT(1) record_count FROM DWH_CUSTOM_OBJECT_NAME_V src WHERE (CLARITY_UPDATED_DATE IS NULL OR CLARITY_UPDATED_DATE >= to_date('1910/01/01 00:00:00', 'yyyy/MM/dd HH24:mi:ss'))) a [CA Clarity][Oracle JDBC Driver][Oracle]ORA-01775: looping chain of synonym
Custom synonyms are created on the Clarity database on all objects. When synonyms exist, and you uncheck an object from Data Warehouse, when an object is unchecked, the view gets deleted in Clarity. If there is a synonym on it, that will cause a problem.
Release: Any Supported Release
This workaround does not guarantee the problem will not reoccur in the future. If you would like to resolve the problem, please apply the solution below
Drop all custom synonyms from the Clarity database. Custom synonyms are not supported, and since you have errors, you must work with your DBA to drop them. This is the actual cause of the problem and might cause other issues with the application.
