Content Manager database connection errors after disabling TLS 1.0

By default, the IBM JDK/JRE that is supplied with Cognos only supports TLS 1.0.

Connection errors for the Content Manager database can occur when TLS 1.0 has been disabled on the server that Cognos is installed on.

To configure IBM JDK/JRE to use TLS 1.1 or 1.2

You must edit the following environmental variable on the server.

In Windows Control Panel > System > Advanced system settings > Environment Variables > New.
Change the values for IBM_JAVA_OPTIONS:

-Dcom.ibm.jsse2.overrideDefaultTLS=true -Dcom.ibm.jsse2.overrideDefaultProtocol=TLSv12
