ORA-29532: Java call terminated by uncaught Java exception: java.lang.RuntimeException: java.lang.Ru

Hi Team,

We created a terradata site TRAS  using jdbc_dblink_config as below

INSERT INTO jdbc_dblink_config (st_nm, jdbc_url, user_id, driver_class)

VALUES ('TRAS', 'jdbc:teradata://< Teradata server name>/database=AP_UAL_P,TMODE=TERA,CHARSET=ASCII', 'AP_UAL_P'','com.teradata.jdbc.TeraDriver');

COMMIT;

Then we created a function PASSWD_TRAS using wrap for DB password of user AP_UAL_P

But when we are testing the JDBC UTIL we are getting below error. This is espically happening after last PSU patching (Oracle PSU 11.2.0.4.180717). What could be the issue? which permissions  on which files must I check?
