The following changes have been made to the Cb Response Server Cluster Management Guide:

  1. Python 2.7 Changes:  The Cb Response 6.2.2 server has upgraded the Python version to 2.7. Because of this and related modifications, the files that must be manually removed to complete a server uninstall procedure have changed. See the "Uninstalling a Cb Response Server" section.  [CB-18079]
  2. In the Ports and Protocols chapter, the API port (default=443) for master-to-minion communication has been added. [CB-16951]
  3. List of Tasks: Added a List of Tasks section in addition to the standard table of contents.
  4. Made various other minor corrections and improvements.
  5. Corrections to Backup and Restore: In the "Server Backup and Restoration" chapter, several corrections have been made [CB-17344, CB-18129]:

  • Removed erroneous "sfd" in the backup procedure for Yum files.
  • Removed Logrotate steps, which are no longer relevant.
  • Removed RabbitMQ cookie step, which is no longer relevant.
  • Corrected a missing dash (was single, should be double) before selinux in the command for Cb installer backups.
  • Corrected the note associated with the Postgres Database step -- the step is relevant when doing a configuration-only backup, not a full backup.
  • Removed multiple obsolete statements and steps that described matching the number of Solr data shards on the server to be restored with those on the backup image.
  • In the Restore Postgres database step, removed pg_catalog.setval('sensor_activity_id_seqsensor_comm_failures_id_seq', 1, false);, which is no longer valid.
  • Removed a step for clearing purge times in the restore section.
