ETL tool cannot extract from database with Advanced Security
Attempting to use the Informatica ETL tool to connect to an Oracle 8.1.7.4 database with Advanced Security. Informatica can connect and successfully extract a very small amount of data (< 100 rows), but with data volumes any greater than that, it just hangs.
If the tnsnames.ora file on the Informatica Server is modified to use the TCP protocal (versus TCPS) and port 1521 (instead of port 6252) then it works fine.
So far, Informatica tech support has been unable to help. Is there some configuration parameter that may need to be modified on the Oracle side?
