About DTS Software

DTS Software, Inc is recognized worldwide as a leader in enterprise storage management technology. Specializing in products for the IBM z/OS, Hitachi VOS3, and Fujitsu MSP operating systems, DTS Software products provide superior function and features that allow managers and users to more effectively utilize their investment in storage systems. The company was founded in 1991. We currently have over 1000 customers in the US, Canada, Europe, and the Far East. You can visit their website here.


Products:

DLm Control Center (DCC)
The EMC Disk Library for mainframe (DLm) is a Virtual Tape Library for IBM compatible mainframes. All the "tape drives" in an DLm are emulated devices where tapes are actually disk files located on backend storage. Each DLm VTE (node) is attached to an IBM compatible mainframe using FICON or ESCON channels, and typically connects to backend NAS storage using dual-channel gigabit network connections.

SRS (Space Recovery System)
The Space Recovery System (SRS) eliminates all types of storage space-related errors. Whether the error is caused by application growth, out-of-date JCL, volume space fragmentation, or job conflicts, SRS steps in to dynamically modify space needs, find available space, and prevent failures. SRS not only improves system throughput, but provides a critical "safety net" that allows installations to achieve higher rates of disk space utilization than could ever be accomplished in any other way.

Eliminate B37, D37, E37 abends and VSAM errors. SRS determines in advance when an out-of-space condition will occur and prevents the error. Production downtime and reruns due to space problems are eliminated.

Support for all types of data. SRS can prevent problems for all types of datasets, SMS-managed or non-SMS, VSAM or non-VSAM, striped, extended-format, HFS, and others.

Automatic Reorganization of Multivolume Datasets. When an application releases a dataset that SRS has extended to an additional volume, SRS can automatically invoke system utilities to copy the dataset back to a single volume if space is available.

Catalog and Tape Error Prevention. SRS does more that just prevent DASD space errors. Duplicate dataset name and NOT-CATLGD-2 errors can be stopped, S837-08 tape errors can be eliminated, and output datasets can automatically be switched to tape units with non-empty automatic cartridge loaders.

Extensions allow better control over space use. The SRSE function allows installations to automatically route desired datasets to VIO, limit dataset space requests, add RLSE parameters, choose optimal tape and disk blocksizes, and control other aspects of dataset usage.



Allocation Control Center

The Allocation Control Center (ACC) provides complete control over the creation and placement of SMS-managed and non-SMS data. ACC allows installations to easily define policies which implement standards for dataset naming, device type, volume selection, and space usage. Because the DFSMS ACS routines rely on the existence of well-defined standards, they are a crucial factor in successful implementation of system-managed storage. ACC then goes beyond standards enforcement to provide advanced features that aid administrators and users in making the most effective use the storage subsystem.


Enforce Dataset Standards.
ACC allows datasets to be created using existing naming conventions and characterics while warning of potential errors during the transition to new standards. ACC's extensive SMF recording, messaging, simulation, and logging facilities make it easy to track and report violations while allowing JCL to be modified "on-the-fly" to meet installation requirements.


Control Dataset Placement.
ACC can make the datasets go where you want! Whether it is directing small tape files to DASD, establishing disk pools, migrating to new device types, or selecting volumes for use based on performance characteristics or space availability, ACC can place datasets where they are best suited, without the need for users to change JCL or programs.


SMS Extensions.
ACC doesn't stop with improving standards enforcement or controlling dataset creation. Storage and database administrators can benefit from extensions designed to make system-managed storage easier to use.

"Keep-Away" algorithm eliminates the need to use guaranteed-space storage classes to place performance-sensitive SMS-managed datasets such as DB2 tablespaces.

Real-time ACS tracing allows users to answer the question "Why is this dataset on this volume?" by providing a line-by-line trace of the logic used by the DFSMS ACS routines to assign SMS classes.



Simulate-2000
Simulate 2000 supports simulation of multiple clocks on one machine. Specifying alternate dates is fast and easy: through an ISPF interface, directly within JCL or through online screens in CICS or IMS/DC.

Online users can control dates by Region, Terminal, User or Transaction. Batch programs are controlled by Job Name, Step Name, Program Name, Job Class, User ID, etc. Alternate dates can be specified for either the job or individual steps.

BREAKING NEWS
Breaking news regarding any customer who use the following products:

DLM Control Center, Space Recovery System, Allocation Control Center and Simulate-2000

IBM z/OS 1.12 no longer honours the unprotected page bit for nucleus storage backed by large pages. The DIF memory update routine has been modified to use DAT OFF updates when necessary.

Note: z/OS 1.12 installations must upgrade to at least SCC SL10202 to run any of the above products.
