Only some databases are listed as supported in the product documentation. How will TIBCO support me if I use an unlisted database?

The list of JDBC DB's listed are the one's we've verified in Quality Assurance and regression testing. You are free to try others and the StreamBase runtime platform does not limit use to those we've listed.

We expect to connect to any JDBC DB with a 2.0 compliant driver that supports transaction isolation. The JDBC specification does allow JDBC 2.0 compliant drivers to be compliant by effectively saying "I recognize that setting" without actually supporting or implementing the setting. We know the DBs we've listed actually implement transaction isolation.

If you run into problems with a database we do not list, we'll still be happy to investigate and will not reject the Support case because of this. If an Engineering fix is required, Engineering may defer action and Support will then advise to use a supported database or other available workarounds.
 

Most JDBC 2.0 databases will work with StreamBase.
