Multiple PDS Configuration
A multiple PDS configuration in Primo allows sites to configure one or more failover servers for the Primo PDS. In this configuration, only one server is active, while the others are inactive.
If a failure occurs in the active PDS server, an inactive server must be started manually to provide PDS service.
Guidelines
When configuring a multiple PDS configuration, the following guidelines must be followed:
-
All PDS servers must be configured using the following page in the Back Office:Primo Home > Ongoing Configuration Wizards > PDS Configuration Wizard
-
All PDS servers must use the host name of the currently configured PDS. Update the pds_configuration_url field on the following page in the Back Office:Primo Home > Advanced Configuration > General Configuration
-
Only one PDS server can be active at a time. All other PDS servers must be inactive. Set the pds_url and pds_internal_url fields on the following page in the Back Office to the host name of the active PDS:Primo Home > Advanced Configuration > General Configuration
-
All FE servers must be restarted after a change to the Primo Home > Advanced Configuration > General Configuration page.
