VTS Manager
A component of tableEXTENZ, DataKinetics VTS Manager is a shared table management product that extends the capabilities of tableBASE. It allows identical shared tables to be used across many LPARs within a Sysplex environment. VTS Manager also provides powerful change-control features for the seamless updating of high-use tables, and increases the performance of the applications accessing your table data.
 Sysplex / Multi-LPAR Operation
|
|
It is possible to use tableBASE data on multiple LPARs within a Sysplex, but it is a precarious management task. With Read-Write tables, it can be a challenge to maintain data consistency across LPARs. There are methods to accomplish this, but they are likely to introduce significant overhead, and would compromise the inherent tableBASE performance advantage.
With tableENTENZ and VTS Manager, you can organize your Read-Only data in multiple LPARs within a Sysplex. By loading all tables from source tables in a VSAM LDS, you can guarantee that data used on different LPARs will be consistent.
VTS Manager provides an immediate ROI, and continues to add value indefinitely in increased utility, maintainability and flexibility. |

Improved Table Change-control Workflow

Workflow complexities
Maintaining large complex systems can be daunting, and maintaining large numbers of tableBASE tables doesn't make it any easier. Standard tableBASE table refreshing can occur in the middle of a transaction, and many organizations will only allow refreshes during downtime for this reason. Further, the sequential nature of table refreshing means that significant delays can be experienced in environments with large numbers of tables.
Table updates can be performed in the background while transactions are being processed on current tables. Updated tables can then be switched in real time, into the production environment without the need for restarting applications, and without interrupting current transactions. Users will not be affected by data updates. |

Increased Performance, Reduced Load Time
|
VTS Manager increases your data access performance over and above the increased performance offered by tableBASE alone.
Improved Startup Performance
Waiting time for tens or hundreds of tables to load from DASD at initialization is measureable, especially if tables are large, and have many indexes associated with them. It can take many minutes, sometimes an hour or even more. With Process Manager, tables are instantly available, fully indexed and ready to use. If your outage costs are $250.00 per second, and it takes one minute to load your table data each day, Process Manager can save your business $15,000.00 per business day.
Improved Run Time Performance
Run time processing performance is also improved. With VTS Manager, you can replace your current local TSR-based tables with shared VTS-TSR based tables--and these can be Read-Only tables. In this way, you can eliminate data update time, table locking overhead and queuing overhead, and increase the percentage of time dedicated to data processing.
