I used this program before to import schema using datapump file, but it is no longer working.
I also tried using oracle client 19.17 from my local machine with the following command
impdp admin/<password>#serviceName credential=OBJECT_STORE_CRED directory=data_pump_dir dumpfile=<object storage url> parallel=2 encryption_pwd_prompt=yes exclude=cluster,indextype,db_link
and got the following error

Any suggestion about what is going wrong? Is there another method to import into autonomous database?

Answer 1

My read of this is that the error in the first case is saying that the parameter for this call (line 20 of your program) is not valid:
dbms_datapump.add_file(handle => job_handle, filename => dump_file_name, directory => credential_name, filetype => dbms_datapump.ku$_file_type_uridump_file);
When this happens, it could be the dumpfile name or the credential that is not valid for this operation. There can be other causes for the UDI error, as detailed in "How to resolve the Data Pump error ORA-31623 UDE-31623 (a job is not attached to this session via the specified handle) ? (Doc ID 1907256.1)" (https://support.oracle.com/epmos/faces/DocContentDisplay?id=1907256.1) but with the combination of the secondary error, and of the issue with the command-line version of the operation as well, I think it likely that the URI for the dumpfile and/or the credential being specified are not valid.
I'm not as sure about the second case, though, because you mention using the 19.7 client. The banned shows the 21.3 client being used, connecting to the 19c server. While the 21c client was made backward compatible, I would want to see the latest client in use to be sure it isn't a bug that has already been fixed. The latest instant client is version 21.8.
