If you ever need to determine the version of the Oracle Workflow server you are running, you can connect to your Oracle Workflow database account using SQL*Plus and run a script called wfver.sql. See: wfver.sql.

In addition, all Oracle Workflow modules, such as the Workflow Definitions Loader, Oracle Workflow Builder, notification mailers, and the Workflow Monitor, automatically verify that the module is compatible with the version of the Oracle Workflow server that it is operating against. This version compatibility check helps to prevent problems such as running Oracle Workflow Builder 2.6.3 against an Oracle Workflow 2.0.3 database.
