The database supports several different types of request processors, which are known as partitions. A partition is specified when a session is established by the CLIv2 Run String addressed in the DBCAREA. CLI operates identically for all partitions. Although the structure of requests and responses is the same for all partitions, the contents vary by partition. The following partitions are supported by the system for general use:

Partition Action Taken
DBC/SQL Processes SQL requests
EXPORT Used by FastExport utility
HUTCTL and HUTPARSE Used by ARC utility
FASTLOAD Used by FastLoad utility
MLOAD Used by MultiLoad utility
MONITOR Processes performance monitor requests

The remaining sections of this document assume use of the DBC/SQL partition.
