The quickest way to obtain support is by e-mail. You can expect a quick response, typically less than an hour, during U.S. East Coast business hours. During the evening, on weekends, and on OCS holidays, response will be slower. Support during non-business hours can be arranged with prior scheduling.

Product End-of-Life Policy
If a version of any of our products is covered by paid support, we will never designate an "End of Life" or "End of Support" date for that product/version. We will answer questions about its use, do our best to track down problems, offer workarounds, and where possible offer patches to your version. Of course some fixes and features cannot be retrofitted into back versions, and you will either have to upgrade to a newer version (at no additional cost) or live with the old behavior.

The one caveat to this policy is where the hardware and/or operating system version on which the product runs is no longer supported by its manufacturer. In this case we will do our best to work with the customer to arrange use of their equipment or to share the additional costs of maintaining such outdated environments.

Steve North really went out of his way to help. He provided custom probes to extend RootCause so it could handle our application, which makes heavy use of shared libraries and spawned processes; it has a very complex design. On many other occasions, OC Systems support staff has been very helpful.
