12.5(1)
This section lists the Unified CCE components on which you can and cannot install this engineering special.
You can install Unified CCE 12.5(1) ES46 on all core Unified CCE components:
Donot install on any other components except following
Check the version of tomcat installed by running <ICM HOME>\tomcat\bin\version.bat . If it is 9.0.37 or higher, then do the following steps:
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.

UCCE
- Router MDS queue alerts needs a configurable threshold |
Caveats are ordered by severity then defect number.
Defect Number: CSCvw05139
Component: mds
Severity: 3
Headline: UCCE - Router MDS queue alerts needs a configurable threshold
Symptom:
Currently there is an SNMP alert generated when Router queue size in increasing
ra-mds MDS time delivery queue size is increasing, current size
is: 799, but will continue to send messages.
This
warning is not based on absolute queue size. It is just an indication that the
queue size has increased continuously. So for every continuous increase in
queue size this warning would pop up and it would go to normal when it
decreases in the next cycle.
Conditions: When router is busy and MDS queue size is increasing.
Workaround: None.
Further Problem Description: This defect provides (by default) the
following 2 new changes to the TDQ warning mechanism.
It
creates a default threshold of 500 on the TDQ depth, below which there won't be
a warning
It
increases the consecutive increase requirement to 50 instead of 10
Both
of these values can be changed by two registry keys, which will not be created
by default. They are as follows:
MDS\CurrentVersion\Process\SyncMaxTDQMinThreshold
- DWORD(32) - overrides the default threshold of 500
above.
MDS\CurrentVersion\Process\SyncMaxTDQIncreaseCount
- DWORD(32) - overrides the default consecutive
increase value of 50 above.
These
registry keys must be created on both sides of the central controller and MDS
must be restarted for them to take effect.
