Custom Configuration Parameters

This page displays customer-specific, custom variables that are not part of off-the-shelf TopBraid solutions. These are commonly used in installation that have multiple environment, such as DEV, SIT and PROD. Initially, the page contains only the instructions for creating a file in TopBraid Composer, how to create custom properties, then upload to a TopBraid server. Once the custom environment variable property is defined, the Custom Configuration Parameters page will display the defined properties. The following image illustrates that the variable 'myEnvVar' is defined using the steps stated on the Custom Configuration Parameters page. Property values can then be entered, such as 'HelloWorld' in this image.

After the 'Save Changes' button is clicked, the variable will be defined in the Graph defined by following the instructions. The page also shows how to access the variable value via a SPARQL query.

Cached Graphs

Note that Cacheable (Database) Graphs only pertains to persistence (Application data storage) using RDBMS or MarkLogic data stores, not TDB. And SDB Database Maintenance only pertains to RDBMS.

Cacheable (Database) Graphs

For graphs stored in relational or MarkLogic databases but not TDB (e.g., see EDG Configuration Parameters > MarkLogic or RDBMS Configuration Parameters) this allows administrators to reset each DB-backed graph's cached triples if they should become out-of-sync with their back-end storage state. This might have happened, for example, if the back-end version has been modified by another user or process. This is common when using TopBraid Composer to modify data on the server.

If Cache all graphs is unselected, a Cache at startup checkbox will appear in each row to let you decide which graphs shouldn't or shouldn't be cached at startup.  If Cache all graphs is selected, all RDBMS graphs are cached upon system restart.

SDB Database Maintenance

If RDBMS is used (not MarkLogic nor TDB), then the RDBMS Vacuum button will delete all "orphaned node" rows from the nodes table in the relational database. Those rows are no longer connected to other data. Use this with care; the onscreen text explains this further.

Lucene Maintenance

This pertains to the Lucene index for Search the EDG. The Refresh Lucene Index button forces an index of all the graph's selected in the Search the EDG configuration.

Product Registration

This page displays any previously entered license information (for example, the number of users or expiration dates). User can now update the registration with the license keys obtained from To register your product simply click the "Change or Update license" link, this will display a button which will allow you to upload your license key. Once uploaded your license key file will be validated and registered for you. Note: prior to 4.5.0 numeric license key files were used, if you still have one of these license key files they were deprecated as of 4.6.0, you will need to contact to get a new license file.

License Registration File

Reconfigure Deployment Descriptor

This can be used to generate a new web.xml for Tomcat installation. See EDG Server Installation and Integration: Tomcat Installation Instructions.
