Benefits of the HSSP function

The high-speed sequential processing (HSSP) function provides a number of benefits.

Some of the benefits of the HSSP function include:

• HSSP generally has a faster response time than regular batch processing.
• HSSP optimizes sequential processing of DEDBs.
• HSSP reduces program execution time.
• HSSP typically produces less output than regular batch processing.
• HSSP reduces DEDB updates and image copy operation times.
• HSSP image copies can assist in database recovery.
• HSSP locks at UOW level to ease bottle-necking of cross IRLM communication.
• HSSP uses utility private buffers, allocated in either 31-bit extended common storage or 64-bit common storage, which reduces the impact on NBA/OBA buffers.
• HSSP allows for execution in both a mixed mode environment, concurrently with other programs, and in an IRLM-using global sharing environment.
• HSSP optimizes database maintenance by allowing the use of the image-copy option for an updated database.
