Unsupported activities: what should I know when using TQ Data Foundation?

Below are a list of unsupported activities to be aware of when using TQ Data Foundation.

Environment – on-premise installations

  • Always take a backup of the workspace prior to upgrades or major changes in the environment. When using a relational database, also back up (dump) the database. When using TDB (Data Foundation built-in triple store), always use the backup and restore utility in TQ Data Foundation, or stop Tomcat to do a snapshot. When using TDB, the workspace contains the TDB database and will contain locks when the data is being written.

  • TQ Data Foundation does not support downgrading workspaces. If you perform an upgrade on a workspace, you cannot re-install the previous version of TQ Data Foundation and use that same workspace.

  • Test customizations and upgrades on a development environment that mimics production prior to production. Customers recieve 2 development licenses for such purposes.

  • Do not delete graphs/collections directly from the file system unless directed to by TopQuadrant support. Use the UI.

  • Refer to the supported platforms page for technology dependencies. If unsure, ask TopQuadrant for assistance in determining if your technology stack is supported. https://www.topquadrant.com/supported-platforms/

  • Install monitoring for disk space and memory. Running out of disk space can cause corruption issues for TDB.

General

  • Test SPARQL or GraphQL queries on a development environment as well. Some unsupported queries can cause a deadlock on your system or be rejected. For example a GraphQL mutation of over 800 top level concepts, or running an expensive SPARQL query.

  • Using TDBLoader is unsupported by TQ Data Foundation.

  • Do not remove system graphs or projects from your workspace using “base uri management” or the file system. This will cause the workspace to become unavailable.

  • Deleting Text Indicies from Server Administration will require a server restart.

SaaS – additional items for SaaS customers

  • SaaS customers should not exceed data load for their instance. If approaching the maximum, do not load large amounts of data without discussing with TopQuadrant support first. Instances can be upgraded to allow more memory for more data.

  • SaaS customers using the instance for performance or benchmark tests should notify TopQuadrant support so that backups can be taken. Doing benchmark testing might impact the availablity of TQ Data Foundation and therefore SLAs will not apply.

  • Do not upload projects or delete projects from your instance. These need to be tested and approved prior to installation.
