BMC CHANGE ACCUMULATION PLUS

Reduce time, resources, and costs for change accumulation

IMS data is growing, IT budgets are shrinking, and IMS experts are retiring. Continuous availability requirements demand fast recoverability, but change accumulation jobs do not generally execute quickly.  How can you protect IMS data, ensure a fast, accurate recovery, and keep IMS online?

BMC solution

BMC CHANGE ACCUMULATION PLUS minimizes DASD usage and I/O by allowing multiple sort tasks and by compressing and reformatting log records, which reduce the amount of sort work space needed for change accumulation. Parallel processing significantly reduces the time required for reading log data sets, which is the most time-consuming step in the change accumulation process.

Features and benefits

• Performs change accumulation to any point in time, allowing faster recoveries with no log input
• Allows creation of incremental image copies that are logically correct as verified with a pointer checking utility
• Processes multiple change accumulation groups with a single pass of the input logs to minimize I/O activity and overall elapsed time
• Employs multiple sort tasks with separate sort areas and optimal key lengths for maximum efficiency and speed
• Automatically selects and dynamically allocates preferred and alternate log data sets

Key differentiators

• Recovery Extension feature  - produces multiple copies of output data sets and allows automatic registration and use of the additional copies
