Understanding the Fundamentals of FTP

File Transfer Protocol (FTP) is a widely accepted standard on almost all platforms that have implemented TCP/IP. It’s used to transfer files between two systems. RFC 959 is the definitive Internet Engineering Task Force (IETF) document that defines the FTP protocol, and it also contains an excellent overview, history, and detailed explanation of the FTP protocol. The objectives of FTP, according to RFC 959, are to:…

MAXM Database Advisor for IMS From BMC Software

The cost that results from downtime due to an unscheduled reorganization of an IMS database is very expensive. Since IMS powers many important applications requiring fast, highly available access to data, any outages cost companies dearly. For this reason, IMS DBAs have always spent significant amounts of time monitoring, analyzing, and circumventing space and performance issues that could cause an outage. In addition, planned database outages that use significant computing resources are scheduled on a periodic basis to permit reorganizations to be performed—whether they are needed or not—to prevent the possibility of an unscheduled outage. The time, knowledge, and experience necessary to perform these maintenance functions on a regular basis are extensive, and many of these DBAs will be retiring in the not too distant future. A new product that increases DBA productivity, improves the utilization of system resources, and expands data availability offers a solution to these issues…

Rapid adoption of Service-Oriented Architecture (SOA) is altering the perception and role of the mainframe in modern business computing, making it much more capable of participation in loosely coupled, standards-based, cross-platform environments. To be more competitive and adaptable to change, organizations with enormous investments in legacy mainframe systems are turning to SOA to  provide more infrastructure flexibility with reduced development cycles and lower costs. However, there are right and wrong ways to go about mainframe SOA enablement…

z/Bottom Line: Keeping Up With the YUMPIES

We are a vocal community when it comes to verbalizing impending danger to our industry. Over the years we’ve hashed out and solved (at least in our minds) the problems of the mainframe world. We’ve most recently been very concerned with the “geriatric” state of our workforce. The very caretakers of the important mainframes are indeed graying, retiring or otherwise leaving, potentially creating a vacuum of human talent to run our magnificent mainframe data centers. We in the industry called for it, and IBM responded by creating an inspired program to cultivate young talent, called the IBM Academic Initiative System z program (www-304.ibm.com/jct09002c/university/scholars/ products/zseries/). This program even features a series of contests with prizes appealing to these younger recruits, including an iPod Nano, a Sony Playstation, even a trip to the IBM Mainframe Lab (was that first or last prize?)—no kidding (www-304.ibm.com/jct09002c/university/students/ contests/mainframecontest.html)! You can learn more about IBM’s Academic Initiative by reading Mike Todd’s article in this issue titled “Students Compete to Master the Mainframe.”…

Compliance Options: A Value Proposition

A few months ago, I received an interesting proposition from a conference organizer. If I and my speaking partner would accept an expenses-paid trip to beautiful San Francisco, I could teach a topic I’m passionate about to a group of eager-to-learn leaders of data governance programs. If I didn’t accept, the workshop wouldn’t be offered at all, and these leaders would miss out on the lessons I could teach them about describing the value of what they do, gaining respect, getting results, and getting funding for their programs…
