  • Ensure to create secrets with requisite confidential credentials for system passphrase, database, MQ server and Liberty. You can use the given configuration files under pak_extensions/pre-install/secret directory.
  • Ensure that dataSetup.enable parameter is set to true and dataSetup.upgrade is set as true when you want to install the chart on a database on an older release version. This upgrades the given database tables and metadata to the latest version.
