This section lists the Unified CCE components on which you can and cannot install this engineering special.
You can install Unified CCE 12.5(2) ES43 on these Unified CCE components:
· Router and Rogger Nodes
Do not install this engineering special other than the following components:
· Router and Rogger Nodes
Installation of
this patch requires that all Unified CCE services be shut down during the
entire period of installation.
If the Unified
CCE Services are set to manual, using the Unified CCE Service Control, start
all the Unified CCE Services.
The installation or uninstallation of this patch does not require a down
time for Unified CCE Router service. You can install the ES in the following
order to ensure no downtime for Router service. Steps are written assuming the
ES installed on Side-A first.
·
Stop Side-A of the Router service and other CCE
services.
·
Install the ES on Side-A. Start on Side-A.
·
Stop Side-B of the Router service.
·
Install the ES on Side-B. Start the Router
service on Side-B.
These steps will ensure the Router service is updated without bringing down
both services together. The Contact Center routing service is operational
without any downtime while installing the ES.
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.

Congestion
Control will cause INCRP to bounce |
Caveats are ordered by severity then defect number.
Defect Number: CSCwm74585
Component: router
Severity: 2
Headline: Congestion Control will cause INCRP to bounce
Symptom: If
using INCRP peripheral, when Congestion control gets invoked, it will cause a
condition where INCRP will not respond to NM, triggering Node Manager to
forcefully restart the INCRP process.
Conditions: Using INCRP and Congestion Control is invoked.
Workaround: None. Once call volume decreases to a point that Congestion
Control is no longer being invoked, INCRP will correctly communicate with NM
and stop bouncing.
Further Problem Description: NM will cause the INCRP process to bounce
during congestion control.
