Annual Salary Survey: IT managers with mainframe and large Unix-based systems skills earn as much as 20 percent more than those in Wintel-based positions.
Enterprises are increasingly recognizing the value of remote workers and are working to develop more flexible, innovative and cost-effective remote access solutions. Companies are helped in this mission by an explosion of wireless access technologies, with the enterprise WLAN market expect to continue its rapid growth rate. Learn what's happening in the wireless marketplace, and what's around the corner for the industry.
The worldwide VPN equipment market is expected to reach two billion dollars in 2004, which bodes well for Linux product developers. Linux should provide enterprises with alternatives to the Solaris and NT products, currently dominating the market, as vendors and users both realize that Linux is out there.
Businesses are quickly implementing virtual private networks in attempts to connect far-flung network users. Despite their popularity, however, two key issues remain: data security and reliable, consistent application delivery. This article explains these key VPN issues, and shows how to implement both security and reliability on your VPN with the implementation of next-generation Quality of Service (QoS), also known as Application Service Quality (ASQ).
Message queuing enables applications on geographically separated systems to interact effectively, without synchronizing activities on communication ends. This makes message queuing a preferred technology for many large-scale e-commerce applications. MQSeries, IBM's message queuing product, can be used for exchanging messages between applications running on the same system, as well as on different systems.
Las Vegas isn't all gambling, showgirls and Sigfried and Roy. It's become one of the nation's hot spots for conventions and trade shows. And competition for business is fierce. Bally's has met the challenge by rewiring their facilites with fiber optic cabling direct to floor pockets in convention and meeting rooms, making it possible to create networks that handle data, voice, video, audio and other media at any desired speed throughout its far-flung meeting areas.
Slow performance from Windows NT/2000 makes you feel like falling to pieces? Network managers know that such performance can be improved by keeping files and free space defragmented. But, there are other benefits to defragmentation. In many cases, defragmentation software can provide an economical alternative to an upgrade of system hardware.
Availability managment is a proactive approach to systems management that identifies and responds to systems events -- before they cause larger problems or even a systems failure. Availability is maximized by continually monitoring system components, identifying events likely to occur and taking preventive action.
GDPS provides all of the benefits of a Parallel Sysplex, while enhancing an enterprise's disaster recovery abilities and managing planned exception conditions. GDPS allows a business to achieve its own continuous availability and disaster recovery goals.
Several years ago, Verizon Data Services rethought its availability strategy, making it a part of the company's operating culture. A redesign of its strategy focused not only on systems and platforms, but involved a combination of a high-performance infrastructure, continuous data accessibility and protection from data loss.
As companies continue to generate vast quantities of data, they must have compact, inexpensive ways to store the information they need to do business. Efficiency and cost control are at the heart of virtual tape technology. Recent software-based, hardware-independent advances in virtual tape technology enable storage managers to create a virtual tape environment from any combination of OS/390 disk and tape hardware - including resources the organization already owns.
Today, most mainframe installations are increasingly interested in TCP/IP implementation and connnecting the intranet and Internet to their enterprise systems to access their legacy data and applicatios. This is where the Netfinity ESCON Adapter offers capabilities not found in other channel-attach products, TCP/IP Direct Connect and the Multi-Path Channel (MPC+) drivers.
New mission-critical e-business applications must be developed more rapidly, meet higher quality standards, and be updated quicker than ever before. This demand for speed is captured in the now familiar terms "Internet time" or "e-time."
With the evolution of network management, more responsibility has been placed upon the "framework" to fulfill the TMN FCAPS model. Typical network operations centers, which support Simple Network Management Protocol (SNMP)-based logical and physical devices, must now be capable of supporting all business units in a uniform fashion.
Java development efforts are sweeping through the enterprise. Existing legacy applications are being reengineered to include Web front-ends. E-business is an idea whose time has come. This article introduces an Object-Oriented Project Size Estimation technique that can help predict the amount of time it takes to design, code and test an object-oriented project.
The SIAC now identifies exact operational functions of the COBOL programs running in its S/390 environment. Using InCert Examiner, SIAC gains the understanding needed to test the "right stuff" and eliminate the uncertainty of guesswork.
A counter view of today's Fibre Channel frenzy.
Database marketing firm Acxiom Corporation relies on SyncSort Inc.'s PipeSort to help slash the company's MVS elapsed time by 40 percent.
