Configuration Database Synchronization

Raw Content; Working title
[PRIYA] Is CME the application name?
When there are updates in the configuration server, then Feature Server synchronizes the following objects.

• SIP Switch objects:
  • CFGDN
  • CFGAgentLogin

Tenant objects:

• • CFGAgentGroup
  • CFGPerson
  • CFGPlace

SIP Feature Server synchronization with configuration database consists of three functional facilities:

• Initial Import
• Real-time Synchronization
• History Log Synchronization

Initial Import

Initial import is the type of synchronization that occurs during the first time Master Feature Server is started. During this synchronization, switch objects and tenant objects are imported from the configuration database. To avoid repeating the import, Feature Server saves/retains initial import flags in Cassandra Database. After the check, Feature Server imports when required.

Important

• Master and confsync nodes perform the initial import of switch objects.
• Master node performs the initial import of tenant objects.

Real-time Synchronization

During real-time synchronization, Feature Server dynamically synchronizes Cassandra database with updates from Configuration database.

Important

• All Feature Server nodes perform the real-time sync of switch objects.
• Only Master and Confsync Feature Server nodes perform real-time sync of Tenant related objects.

History Log Synchronization

History log retrieval synchronization occurs when Feature Server is disconnected and then reconnected to the Configuration Server. During this process, Cassandra is updated with all the changes in the configuration database during the time Feature Server was disconnected. If the history log is lost owing to a Feature Server outage, reimport mechanism is triggered automatically. For configuring Reimport procedure, please refer the link: https://docs.genesys.com/Documentation/FS/latest/Admin/reimpcassdb

Important

• Non-master/confsync The FS nodes perform Historical Synchronization of Switch related objects.
• The Master and confsync Feature Server perform Historical Synchronization of Tenant related objects.
