ORA-00980: synonym translation is no longer valid
This error usually means that the synonym used is based on a table, view, or synonym that no longer exists. in order to fix it you will need to replace the synonym with the name of the object it references or re-create the synonym so that it refers to a valid table, view, or synonym. However, this is not always simple. following are some common causes and suggested solutions.
1) If you imported a specific schema, it is possible that one of the sysnonyms is pointing to an object on a different schema that is simply not there. run SELECT * FROM all_synonyms and verify that all the table name are there and reachable.
2) If you imported from a different version it is also possible that that the synonym is pointing to an object that does not exists in the new version. This could be due to the fact that this component was not installed on the new version or that the component is not in a valid state.
SELECT comp_name, version,status FROM dba_registry and make sure that all the components are valid.
3) it is also possible that object is there but you don’t have access to it. connect as system and do the SELECT * FROM dba_synonyms WHERE owner=’YOUR USER”. again, make sure that your user have access to all the objects under TABLE_NAME. If not, grant it.
4) if this issue happens during import or export, add trace=y to the imp/exp command (imp user/pass file=filename.dmp trace=y) This will create a trace file that will provide more information on what is failing.
