Configuring the Fields in the Subscriber Sessions Table (SRC CLI)


The format of subscriber identity information stored for each session is managed by the subscriber sessions table, which is controlled by the cluster’s client node/management servers. The configuration of the subscriber sessions table is copied to all nodes in the cluster, so all nodes operate with the same information.

The preconfigured schema defines the table’s indexes. The default set of database fields in the subscriber sessions table addresses the needs of most carriers, however you can modify certain fields to address unique needs and situations. SSR Database Schema describes the default configuration and fields that can be modified.

  7. (Optional) If the type is specified as either binary or string, specify whether the value is variable. If set, the SQL data type will be varbinary or varchar, respectively. For example, to specify the type as variable:
