About Cisco Unified CCE (and Unified CCE Engineering Specials)


The Engineering Special (ES) is a cumulative update applied at the Unified Contact Center Enterprise (CCE) server level. Each ES includes all features, security patches, and resolved caveats from the base release, tailored to specific server roles within the system. The ES packages are categorized as follows:

  1. Router/Logger/Rogger ES – Applies to Router, Logger, and Rogger servers.
  2. Peripheral Gateway/Dialer ES – Applies to Peripheral Gateway and Dialer servers.
  3. Admin Workstation/Distributor ES – Applies to Admin Workstation, Distributor, and Admin Client servers.
  4. Common ES – Applies to common CCE components across all server types, such as Diagnostic Portico, Tomcat, and other security-related updates.

 

Each ES is cumulative within its specific category. These ES packages are released quarterly, but only if updates are available for that category. If no changes are required for a category in a given quarter, an ES for that category will not be issued.

To ensure the latest patches are applied:

Unified CCE Engineering Special Installation Planning


Planning for maintenance window and downtime


You can use graceful shutdown procedure to install this ES with Zero down time. To avail this Zero Down Time feature, ES68 in Rogger/Router server, ES69 in Peripheral Gateway, ES70 in Admin Workstation/Distributor servers is a prerequisite to be present in the system.

Note: Prior to initiating installation or uninstallation, ensure that only one user session is active on the target servers. Concurrent user logins are not allowed during this process.

Installing Unified CCE 12.6(2) ES101


 To install the Unified CCE 12.6(2) ES101 with maintenance mode (Zero Downtime), follow the steps:

  1.  Using maintenance mode stop services on side A.
  2.  Install this ES on side A and restart VM.
  3.  Start services on side A.
  4.  Using maintenance mode stop services on side B.
  5.  Install this ES on side B and restart VM.
  6. Start services on side B

For more information about graceful shutdown, please refer to Administration guide for unified contact centre enterprise release -https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cust_contact/contact_center/icm_enterprise/icm_enterprise_12_6_2/administration/guide/administration-guide-for-cisco-unified-contact-center-enterprise-release-1262/ucce_m_graceful-shutdown.html?bookSearch=true

NOTE: During the installation or upgrade process, Tomcat will reset all related registry entries to their default values. It is highly recommended to back up any existing registry entries prior to proceeding with the installation. Failure to do so may result in the loss of custom configurations.

Uninstall Directions for Unified CCE 12.6(2) ES101


 NOTE: Tomcat version will be upgraded during installation but will not be downgraded during un-installation of this ES. If the ES needs to be un-installed, then downgrade the Tomcat manually using the Cisco Upgrade Tomcat Utility to 9.0.89 or lower versions.

 

To Uninstall the Unified CCE 12.6(2) ES101 with maintenance mode (Zero Downtime), follow the steps:

  1.  Using maintenance mode stop services on side A.
  2.  Uninstall this ES on side A and restart VM.
  3.  Start services on side A.
  4.  Using maintenance mode stop services on side B.
  5.  Uninstall this ES on side B and restart VM.
  6.  Start services on side B

Note: Remove patches in the reverse order of their installation. For example, if you installed patches 3, then 5, then 10 for a product, you must uninstall patches 10, 5, and 3, in that order, to remove the patches from that product.

Security Updates

 

Note: Upgrading Tomcat will reset all Tomcat-related registry entries to their default settings. Any custom configurations will need to be reapplied after completing the ES installation.
