tableBASE Process Manager provides a new and higher level of data and table management. It is a three-tiered system based on the table-sharing capabilities of our tableBASE VTS product, and it has built-in features that will permit the tableBASE family of products to capitalize on the advanced multithreading capabilities inherent in today’s mainframe technology.
tableBASE Process Manager incorporates Linear Data Sets (LDSs), a standard IBM technology, into its architecture, giving you the means to increase the performance, flexibility, manageability and security of your applications without ever touching a line of application code. With tableBASE Process Manager, the LDS contains an image of the shared table space regions, which means that table data is paged in as needed, eliminating entirely the initial overhead otherwise required to load tableBASE tables into memory.
A new VTS switching feature permits seamless 24/7 switching from one set of tableBASE tables to another while applications and tableBASE VTS-TSRs are up and running. Started transactions will complete with the tableBASE tables that are being taken offline, and new transactions will start up with the set of tables that are being brought online.
tableBASE Process Manager provides the following benefits:
- Performance: Eliminating the need to open tables and rebuild indexes after system shutdown; updating libraries without taking down your production application; increasing transaction throughput with shared read-only tables, eliminating enqueues and table locks where not required; reducing start-up time after system termination with a warm start; synchronizing live updates to active tables.
- Flexibility: Share LDSs, and therefore data, across LPARs; run more than one maintenance level of tableBASE (e.g., production, test, Q/A) on the same LPAR; define multiple VTS-TSRs under a single second-tier VTS Manager; designate individual table space regions as read-only or read/write; refresh table data content without interrupting the running transaction or application; define, start up, shut down or delete VTS-TSRs as operational demands require.
- Manageability: On-demand and/or pre-scheduled table data updates; parallel testing capabilities to safely prove enhancements before going to production; application-appropriate data access via read-only or read/write table space regions; ability to change shared table data without changing the shared table name used by the application.
- Security: Standard IBM resources such as RACF to secure access to LDSs; read-only table spaces to add another layer of protection to corporate data; segregation of update applications to specific read/write table space regions.
