Anzo Upgrade Notes

If you are upgrading Anzo from a previous release, review the following notes for important details about upgrades to Anzo platform components.

Review Your License when Upgrading Between Major Versions

If you are upgrading to a new major version of Anzo, such as from 4.x to 5.x, your Anzo license may need to be updated to add the new version. Before upgrading between major versions, contact Cambridge Semantics to review and update your license if necessary.

Upgrade the Anzo Unstructured Leader and Worker Nodes

Updates to the Anzo server typically include changes to the Anzo Unstructured (AU) cluster software. If you are upgrading from a previous release, upgrade the AU worker and leader nodes to the latest version. For instructions on upgrading an AU cluster, see Upgrading Anzo Unstructured.

When upgrading the AU software, the leader and worker applications must be upgraded at the same time using the same installer so that the software versions are identical across the cluster. You cannot upgrade the worker nodes without upgrading the leader and vice versa.

Upgrade Any CData ODBC and JDBC Drivers

Updates to the Anzo server often include improvements to the CData ODBC and JDBC drivers. To take advantage of the improvements, Cambridge Semantics recommends that you upgrade any existing ODBC or JDBC drivers with the latest version after upgrading Anzo. For instructions, see Downloading the Anzo ODBC and JDBC Drivers.

Updating the AnzoGraph Graph Data Interface Extension

If you do not upgrade AnzoGraph when updating Anzo, and Cambridge Semantics Support recommends that you update the AnzoGraph Graph Data Interface (GDI) extension for your existing installation, you can follow the instructions below to replace the existing extension. Your Customer Success Manager can provide the new gdi-<version>.jar file.

  1. Download the gdi-<version>.jar file provided by Cambridge Semantics to the AnzoGraph leader server.
  2. Remove or move the existing GDI .jar file from the <install_path>/lib/udx directory on the leader server.
  3. Copy the new gdi-<version>.jar file to the <install_path>/lib/udx directory on the leader server.
  4. Run the following command to change the owner of the file to the anzograph user:
    chown anzograph:anzograph -R <install_path>/lib/udx/gdi-<version>.jar

    For example:

    chown anzograph:anzograph -R /opt/cambridgesemantics/anzograph/lib/udx/gdi-4.0.0-202205280158.jar
  5. Restart AnzoGraph to apply the update.
