tableBASE VTS datasheet

DataKinetics® Product Datasheet: VTS®
VTS: Shared in-memory tables
tableBASE® allows you to access your most critical data directly
from memory, at memory speed, allowing for increased capacity
and volume of online transactions processed, while decreasing
the time needed to process those transactions.
VTS allows for multi-region access to special shared in-memory
tables. These tables, known as VTS-TSRs, reside in their own dataspaces, and can be accessed by any number of regions. The
result is a significant decrease in the memory requirements of
multi-region systems, and a significant reduction in the time
needed to load tables at initialization of the application.

tableBASE, by itself, is enough for some mainframe operations.
In cases where there are many tables accessed by many regions,
and in cases where large tables are accessed by many regions,
sharing tables can be beneficial.

How VTS works
When multiple regions access the same data, they all access it
from their own dataspaces—one copy of the data is in memory
for every region (Figure 2). Since the tables are populated from
a single source (DB2, VSAM, etc.), they are loaded sequentially.
Figure 2: Multiple regions using multiple copies of data
VTS shared in-memory tables can be used in place of the inmemory tables within a specific region’s dataspace (in the local
TSR). Shared tables use dedicated non-region-specific dataspaces that can be accessed from other regions (Figure 3). In this
way, many regions require only one copy of the data, dramatically reducing the requirement for memory and caching resources,
and reducing the amount of time required for initialization of
the application.
A recent customer had 60 regions all loading data into memory from a single source. It took hours to load all the tables into
each region, and then their systems had to maintain this data in
memory (and to cache it) during business hours. After installing
VTS, they were able to load the shared tables in memory in just
a few minutes, and all regions had access to it immediately after
initialization. The demands on their systems were reduced to
1/60th of that which was required prior to installing VTS.
VTS features
Compatibility
VTS is compatible with DataKinetics’ tableBASE base product.
Accessing VTS tables
The tableBASE API contains the capability to access shared VTS
tables.
64-bit support
VTS is a 31-bit application; it does not use virtual storage above
the 2G bar. z/OS fully supports 31-bit applications.
