3.0.0

Upgrading RED

Version 10.2.0.0 has potentially breaking changes for upgraded repositories; therefore, upgrades should be tested thoroughly before upgrading production environments:

  • All ODBC, Database, Extensible Source Connection and Scheduler Configuration credentials have moved to the RED Profile, therefore each user of RED should generate their own local profile file (see the user guide for details) to continue using RED.
  • For new installs, from RED 10.2.+, you will find the the wsl_scheduler_profile_maintenance host script under your Host Script's in your RED metadata repository. For upgraded repositories you will need to load this script into RED manually from <RED_Installation_Directory>\Administrator\Scripts\wsl_scheduler_profile_maintenance.ps1
  • All Azkaban components require upgrading and the encrypted Scheduler profile records added to redadmin.ws_scheduler_profile (see the user guide for details) in order for jobs to run.
  • Post upgrade it is encouraged to remove all credentials from the metadata since these should now reside in the in-memory session level credentials only. Run the following update on the metadata to achieve this: 
    Code Block
    languagesql
    titleRemove credentials after upgrade
    -- Remove credentials from Database, ODBC and Extensible Source connections
UPDATE red.ws_dbc_connect
SET dc_extract_userid='', dc_extract_pwd='', dc_admin_userid='', dc_admin_pwd=''
WHERE dc_type IN ('D','O','Z');

-- Remove credentials from Scheduler Configuration
UPDATE red.ws_wrk_external_scheduler
SET wes_dashboard_userid='', wes_dashboard_pwd='', wes_restapi_userid='', wes_restapi_pwd='';

Upgrading Azkaban

This version 10.23.0.0 has changes to the Azkaban components; therefore, all Azkaban Web Servers and Executor Servers need upgrading as well as the Azkaban metadata.

  • In RED 10.2 3 Advanced Connect is always enabled and therefore there are new azkaban.local.properties fields (and response.xml tags) required that support this feature. Automated install script will need to take into account these new fields. Each of the Azkaban metadata, Azkaban Web Servers and Azkaban Executors will need to be upgraded to work with this release.
