SBR Databases can be created with different sized session databases for each Policy and Charging Mated Sites instance. Each instance of the Session SBR Database can be sized appropriately for the expected level of signaling traffic at that set of mated sites.
Session SBR Databases can be resized without loss of policy or charging data and without disruption to policy or charging signaling. Binding SBR Databases can be resized without loss of binding data and without disruption to policy signaling.
For further information about how to resize an SBR database, refer to SBR Database Resizing Plans.
