In my experience one of our downstream extract from Oracle 11g to SQL SERVER, It was reported either job not finishing or time out.

We found SQL Server side connection driver not latest version, which was upgraded.

Network data transfer byte rate was increased.

Records to Commit rate was increased

With all changes on SQL SERVER our extract was fast.

One of their vendors, using SQLSERVER, is having an intermittent issue connecting to the oracle database; their sqlserver program is sending a generic timeout expired exception. We've reviewed the sqlnet log, alert log, listener.log, and the audit trail for connections for this system. While we have found frequent TNS 12535/12170 combinations from that server in the alert log and TNS 12518/12564 from the enterprise manager agent in the sqlnet log file, all of those errors are unrelated to the specific instance that we're trying to track down (as a side, we are investigating resolutions to those as well)
