Session Database References

The product documentation of SAP Convergent Charging includes one database reference for the SAP CC Session Database component:

SAP CC Session Database

SAP CC Session Database is a back-end database of SAP CC Core Server, the component of the SAP Convergent Charging software product provided by SAP for your industries.

SAP CC Session Database contains the different data related to the business objects handled by SAP CC Core Server during session-based charging operations via the Online Charging Services (OCS) implemented in your SAP system landscape to dynamically price and charge the customer usage of digital services.

Recommendation

Refer to the SAP CC Application Help (aka SAP CC Library) for more information about the system landscape architecture and the deployments of SAP Convergent Charging.

Technology

SAP CC Session Database supports the Oracle and Oracle RAC database technologies.

Database Editions

The edition of the Session database corresponds to an enterprise edition which ensures high performances, high-volume data management, and high-availability (HA) feature.

Reserved Storage Spaces

SAP Convergent Charging defines some reserved spaces named tablespaces on one or multiple disks where the database systems store data objects like database tables and database indexes. This optimizes the storage of data in the database systems of the Session Database.

You create this reserved storage spaces and define a maximum size, an initial size and other options like the minimum size of each subelement into a tablespace.

Database Partitioning

SAP Convergent Charging provides advanced functions to ensure the highest level of performance (high volume, very high end-to-end throughput and latency) and high availability.

These functions require database partitioning to improve the database performance with large and very large databases. Refer to the SAP CC Sizing and Performance Tuning Guide and SAP CC Sizing Guidelines to determine when the database partitioning applies to your business requirements.

Note

SAP CC provides some specialized SQL scripts to setup the database schema with partitions in your database systems.
