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.
