Downgrading Tanzu Greenplum Text

You may downgrade Tanzu Greenplum Text versions 3.7.0 and higher to Tanzu Greenplum Text version 3.6.0. Downgrading a Tanzu Greenplum Text system installs the older Tanzu Greenplum Text software release on all hosts in the Greenplum cluster, and then downgrades the Tanzu Greenplum Text system.

Downgrading a Tanzu Greenplum Text Release

  1. Download the Tanzu Greenplum Text 3.6.0 installer for your platform from Tanzu Network.

  2. Extract the release package.

    $ tar xfz greenplum-text-3.6.0-<platform>.tar.gz
    
  3. Verify that ZooKeeper and Tanzu Greenplum Text are running.

    $ gptext-state
    
  4. Run the Tanzu Greenplum Text installer.

    $ greenplum-text-3.6.0-<platform>.bin -d $TARGET_GPTEXTHOME 
    

NOTE: You must install old and new Tanzu Greenplum Text versions under the same parent directory.

  1. The installer prompts you to accept the license agreement and to choose and create the installation directory.

  2. The installer verifies the environment to ensure that prerequisites are present, such as Python and Java. If any problems are discovered, the installer outputs an error message and stops. Correct the problem identified by the error message and then follow the instructions in the message to continue downgrading.

  3. After the downgrade has completed, source the greenplum-text_path.sh in the 3.6.0 Tanzu Greenplum Text release directory and run gptext-state healthcheck to verify the Tanzu Greenplum Text system:

    $ source /usr/local/greenplum-text-3.6.0/greenplum-text_path.sh
    $ gptext-state healthcheck
