Patching JDBC/OCI - Trend Micro Office scan
Here's one information for any of you trying to patch JDBC/OCI.
My company is using Trend Micro Office Scan. What I found out today - when downloading patch 9367425 from metalink, Trend Micro will intercept the zip file on the fly, insert it's own classes into the zip, and make oracle java classes dependent on Trend Micro.
The result is - when this patch is applied on server, OCI is not working any more. The error message is complaining about not being able to find com.trend.iwss.jscan.appscan.runtime.session.
The solution? Bypass the anti-virus when downloading the patch.
