Upgrade the TimesTen Custom Resource Definitions (CRDs)

To upgrade the TimesTen Custom Resource Definitions (CRDs) in your cluster, use the ttcrd chart from the new release.

This example upgrades from TimesTen release 22.1.1.19.0 to 22.1.1.20.0. For more information about TimesTen releases, see Overview of release numbers in the Oracle TimesTen In-Memory Database Installation, Migration, and Upgrade Guide.

Let's assume you previously created the new_kube_files directory and unpacked the new release of the TimesTen Operator distribution into this directory.

  1. Review the current ttcrd release that is deployed in your namespace.
    helm list

    Output.

    The ttcrd chart version is 2211190.1.0 and appversion is 22.1.1.19.0 corresponding to the TimesTen 22.1.1.19.0 release.

  2. On your development host, change to the new_kube_files/helm directory. 
    cd new_kube_files/helm

    This directory contains the new release of the charts. For more information about the helm directory, see Set Up the Environment.

  3. Upgrade to the new release.
    helm upgrade ttcrd ./ttcrd

    Output.

    Release "ttcrd" has been upgraded. Happy Helming!
