Distributed DBs Don’t Live Up To Hype

ddbVendors love to solve problems by declaring them solved. Declarations don’t require much research and development, don’t take much time to produce and don’t cost much to make.

Unfortunately, simply saying something is so doesn’t make it so.

Client/server database systems, for example, are not necessarily distributed database systems. No matter what their vendors might say — and some vendors are trying to equate the two — the two are different.

Spotting a client/server database system is pretty easy. A server machine runs database server software. Some machines networked to that server run client software that uses the data-management services of the server database software. Read More »

Netware 4.0 Was A Powerful Beast

ntwwapWhile most users will greet NetWare 4.0 with open arms when it is introduced next month, those desiring sophisticated, multiplatform storage management will be left wanting.

Although it was slated for release in NetWare 4.0, Novell Inc.’s Storage Management Services (SMS), a technology designed to ease backup by integrating much backup processing into NetWare itself, won’t be delivered entirely in 4.0, officials confirmed.

“We’re waiting for it, and our customers are clamoring for it,” said one tape-backup vendor who asked to remain anonymous. “It’s late and incomplete. Users need it, and [not delivering it] is hurting users.”

Which Factors Decide Hard Drive Recovery Costs?

Hard drive recovery costs may vary from case to case. Prices cannot be the same for every type of hard drive and for every kind of hard drive failure. There can be a range of factors which decide what would be the total data recovery cost will be for you. Some of these factors are listed here.

save-moneyOne of the very basic factors on which the cost of hard drive recovery depends is the type of hard drive itself. Hard drives differ in interface; e.g. recovering data from an SCSI drive would be more costly than that from an IDE drive. Similarly, it is obvious that there would be different costs associated with data recovery from drives of different sizes and model.

Another common factor deciding hard drive recovery cost to a great extent is of course the type of damage rendered to the drive. A physically damaged drive usually requires more effort for data recovery than a logically damaged drive.

The type of operating system also has an impact on the cost of data recovery. Data recovery pricing for the UNIX file system would be higher than for the Windows Operating system, as an example.

Besides, the above mentioned factors, often the attempts made by the user to recover the data can also result in an increase in the costs (as well as dangerous chemical exposure) because in most cases, such attempts further increase the damage.

Data Recovery From A Drive That Beeps

When you have a hard drive that is out of order, not completely non-responsive but producing a beeping sound, it means that the motor is trying to spin the drive but cannot do so and hence you hear a sound. This can happen due to two major hardware problems – both of which are of a serious nature. When a drive is not running, the heads of drive park either in the center or at the edge of the platter and never come in contact with the data area of platter. A problem arises when the heads park over the data area once the platters stop spinning. Hard drive data recovery in such cases can only be done in a lab by a professional who will carefully remove the heads from the platter and may replace the heads if needed.

The second possible cause of such beeping sounds can be the seizure of motor spindle around which the platters rotate. If the spindle gets damaged, it may stop spinning and in such cases, the hard drive data recovery can be performed either by replacing the faulty spindle or by moving the platters with their heads to a new hard drive altogether. In both cases, effective data recovery requires the services of a professional. Damaged hard drive units should NOT be touched by an amateur. Read More »

Jocks And Computers: The NFL Story

nflFootball is big business, and the Super Bowl is the biggest of the big. The National Football League, a PC Week Corporate Lab Partner, spent two weeks building a miniature village near the site of the Super Bowl, complete with stores, houses, offices, an amusement park and a satellite-dish forest. And this village is becoming increasingly computerized.

The day before the Super Bowl, NFL officials took us on a tour of the official statistics control center. During the game, this small room is a hotbed of activity as each play, participant and result is entered into a Xenix-based multiuser system. This system, written by a small consulting firm called Emphasys, runs on a network of Zenith MultisPort laptops. During the game, statistical summaries are selected by the NFL and synchronized with the in-house Read More »

R:Base Was Pure Dopeness

dosWhen DOS 2.0 was brand-new in 1983, I was using Lotus 1-2-3 to maintain a mailing list. It was easier than using EDLIN and the DOS Sort utility, but it still seemed like a clumsy, error-prone approach.

That’s when I decided to get acquainted with my first database package — Microrim’s R:base. My reaction was love at first prompt.

That early experience with R:base gave me some convictions about the proper way to configure a database. Those convictions persist to this day, although I was often forced to use other tools because of a client’s preference.

When I recently had the chance to get reacquainted with Read More »

IBM Still Powers The IT Industry

ibmspIBM is on a roll, at least as far as PCs are concerned. Granted, the company has just announced the Mother of all Corporate Losses, and John Akers has joined the ranks of presidents without portfolio. Nevertheless, there’s one part of the company that appears to have gotten its act together and is competing effectively — the Personal Computer Co.

The descent into the netherworld of non-competitiveness took a while: After all, IBM has always been a force, and what might have killed other companies just weakened Big Blue.

Yet from 1988 to the end of the third quarter of 1992, it was pretty darn hard to justify buying a Blue box, and fewer and fewer customers did. Prices ranged from merely exorbitant (50 percent more for the same configuration) to outrageous (250 percent more for similar systems). Read More »

cmaThe U.S. semiconductor industry has staged a startling comeback from its dark days of the mid-1980s.

It was in 1986 that American semiconductor companies, which had once enjoyed a 70 percent share of worldwide sales, watched their market share slip below 40 percent and their number of dynamic RAM manufacturers dwindle from 11 to two. Japan quickly capitalized on the erosion of the U.S. semiconductor industry and vaulted to the top.

“People seriously thought there wasn’t going to be a semiconductor industry in the United States by the end Read More »

Oracle “Glue’s” It All Together

orclOracle Corp. customers will see the benefit of the company’s new Glue middleware immediately: Glue’s architecture is built to take advantage of the optimization features of the Oracle database server. But while Glue has a strong architecture, its success will depend on its acceptance and use by other software vendors.

PC Week Labs examined a beta version of Oracle’s middleware, a software layer that allows front-end software to talk to back-end databases. Glue takes middleware a step further by including E-mail and personal digital assistants (PDAs) as data sources that can be linked into the corporate data network.
