IBM Z Table Accelerator

Maximize IBM Z transaction throughput and minimize system resource usage with a real-time, high-performance in-memory table manager

IBM Z® Table Accelerator is a memory-resident table-management system that handles row data in similar ways to a database management system (DBMS) but with substantially faster performance.

IBM Z Table Accelerator is ideal for organizations that need to get every ounce of power out of their mainframe systems in order to maximize performance and transaction throughput, while still minimizing system resource usage at the application level.

It allows for more powerful and efficient applications while lowering mainframe total cost of ownership and reducing operational spend. It can also help to increase the timeframe between upgrade capital expenses.

Benefits Batch processing optimization

Help processing by reducing the pressure considerably in many I/O (In/Out) - intense batch applications.

Increase in capacity

Use your legacy applications as the starting point for new data-driven applications with externalized business rules and logic, permitting agile development.

Reduction in resource usage

Your mainframe applications are able to process at an improved rate, using far fewer CPU, I/O, MIPS/MSU, or real and cache memory resources.

Controlled operating costs

Faster applications use fewer resources and cost less to run. Applied to several applications, this can save you 5%–10% on yearly operating costs.

Rules processing optimization

Maintain your business rules outside of legacy applications, from highly maintainable high-performance in-memory tables.

Lower cost per transaction

Sharply reduce the number of I/Os used by mainframe applications, significantly reducing the CPU cost associated with those transactions.

Batch application and Online Transaction Processing accelerator

Optimize batch applications or Online Transaction Processing applications with very high transaction throughput rates to use fewer resources (CPU and I/O (In/Out)) while improving application performance. Sharply reduce batch run times and dramatically improve overall system performance.

z/OS, Db2, and IMS version compatibility

You can operate IBM Z Table Accelerator on all version levels of the z/OS operating system; on all version levels of DB2 (and in a Db2 stored procedure environment with multiple Task Control Blocks; and all version levels of IMS (with the optional IBM Z Table Accelerator /ISPF interface supporting all version levels of Interactive System Productivity Facility).

Virtual Table Share Manager

With Virtual Table Share (VTS), you can augment the IBM Z Table Accelerator core product with the capability of sharing table data across regions.

Agile market-reactive application solution

Run applications almost as fast as embedded-rules applications, but with business rules externalized so that they can be updated in hours or days rather than weeks or months.

Sysplex support

Run IBM Z Table Accelerator with full capability in a Sysplex environment. Read-Only (R-O) tables are fully supported across LPARs—updates to R-O tables are managed using Linear Data Set mappings. Read/Write tables can be managed using Db2 stored procedures. Datasets are fully supported across all MVS (Multiple Virtual Storage) images in a GRS configuration.
