DBREPAIR

DBREPAIR's architecture centers around its core module, which executes the database checking and repair operations. This module interacts directly with the CA IDMS database, accessing and modifying data structures to identify and correct errors. The utility operates within the z/OS environment, leveraging system services for I/O and resource management.

The primary components include the DBREPAIR module, the JCL interface, and the reporting subsystem. The DBREPAIR module is the core engine, responsible for executing the CHECK, REPAIR, and REPORT commands. The JCL interface provides the means to configure and control DBREPAIR operations, specifying the database to be processed, the type of operation to perform, and various configuration parameters.

The reporting subsystem generates detailed reports on the database status, including the errors found and the actions taken. Communication between these components is primarily through internal function calls and data structures within the z/OS environment. DBREPAIR does not expose any APIs.

The utility uses the CA IDMS database as its primary storage mechanism, accessing and modifying data directly within the database files. There are no specific network ports or external network requirements for DBREPAIR. The utility is executed within the z/OS environment and interacts directly with the database files.
