The ability to perform patch updates on the UEM VMs is now supported.
Under normal circumstances, available software updates are perfomed on the UEM through the standard USP upgrade process as described above. However, under certain circumstances patch updates may be made available for the UEM to minimize system downtime. The patched software files are applied manually as per the instructions that follow.
The UEM is comprised of the following software modules:
Service Configuration Manager (SCM)
Life Cycle Manager (LCM; note that this is also sometimes referred to as the VNFM-Proxy)
Service Level Agreement Manager (SLA-M)
The UEM patch process allows for each of these modules to be updated individually.
UEM software patches are distributed as a binary file containing a number of files for each of the three software modules identified above. The files are organized into separate directories based on the module:
SCM patch upgrade files are contained in scm/:
LCM patch upgrade files are contained in vnfm-proxy/:
SLAM-M patch upgrade files are contained in sla-m/:
UEM VMs are deployed in an HA cluster. The patch update process must be performed on each of these VMs as described in the procedure that follows.
