MERLIN - the future of OS/2

The Merlin beta was officially launched in June, although it was July before many copies became available in the UK. Even then, there was an unfortunate scarcity of copies that frustrated a lot of interested and enthusiastic people. If it is any consolation, one of the first actions of Simon Dyson, following his promotion from head of IBM software in the UK to a similar European position, was to have more copies made. A few EurOS/2 members have obtained copies, of which I'm one. Although the gamma is now in existence, and the real thing isn't far away, here are just a few personal impressions of the Merlin beta.

My immediate impression was of a brighter user interface. All of the windows and controls have a more sculptured, 3-D appearance. The default font has been updated, so text appears crisper and more attractive. These changes, combined with more colour, give an impression of modernity that is encouraging. To me, the very clever context dependent automatic help is irritating. It pops up and gets in the way just when I'm trying to do something. For some of my colleagues, it even hung the system. The OS/2 Warp Centre also got in my way, floating to the top and obscuring useful buttons on applications. But that's not a fair judgement for the typical user, who may be less impatient and less familiar with OS/2.

Voice recognition as an integral part of the system has a good deal of interesting potential, and I can imagine a number of users who would be keen to dictate directly to the computer. However, during the beta it was impractical to get very far with this, as a particular microphone is needed (not easily obtained outside the US for the moment) and one ideally needs to have an American accent! But I'm looking forward to trying out the UK version when the product is fully released.

What of the significant technology developments in Merlin? To me, further emphasis on Java and OpenDoc show the way forward. Java is one of the Internet based ideas that may radically alter the direction of computing in the near future (see the article on the "Java Earthquake" below). As Java becomes more familiar, and applications start to pour out from the many developers who have enthusastically embraced it, IBM hope to see OS/2's popularity increasing as the best available Java platform. Likewise, the development of compound documents really needs better technology than OLE and it would be encouraging to see OpenDoc gather more momentum. So it is good to see these standards built into Merlin.

Although I haven't been able to try it yet, the mail functions for Merlin promise a great deal. A new Lotus Notes mail client provides not only basic e-mail functions within the LAN, but also builds on the Notes replication model to ensure that e-mail connectivity can be easily maintained by users who switch between LAN connection and mobile use through a modem. Notes Mail will include a full featured word processing editor with multiple fonts, colour and formatting options. But in addition, Notes Mail will operate as an Internet mail client, providing POP3 and MIME facilities, allowing users to receive all e-mail in one place, and including the ability to send and receive attachments of any kind.

How about stability and compatibility? Well, it crashes from time to time, which is only to be expected with a beta. The gamma is said to be very much improved (see below). But I was pleasantly surprised that I was able to run IBM's Restricted Workplace Shell and our own network login programs without much difficulty. I found that the Object Rexx seemed to work better than the "Classic" Rexx, and had to make a few small changes in my programs, but nothing major. The system was running well enough that I've been using it for Visual Age Smalltalk development work. It seemed fast and stable enough that I preferred it to my rather slow regular machine. So I'm optimistic that the final released version will be speedy and reliable.

For another individual perspective, see Kris Kwilas' Merlin comments at the [EurOS/2 Web Site] and the July edition of the [OS/2 e-Zine!] carried a Merlin review. The official IBM story can be found at [the OS/2 Warp Home Page].

MERLIN gamma shows promise

Based on an article in PC Week Online August 23rd, 1996, by Norvin Leach

IBM appears to have solved many of the installation problems that plagued the final beta version of Merlin, the forthcoming OS/2 Warp client, according to testers of the recent gamma version. The gamma, sent to fewer than 200 users on Monday, was designed to clean up the last remaining bugs in the product, most of which revolved around installation issues.

IBM hopes to complete the code and ship it to manufacturing by the end of the month, IBM officials said. The formal launch for Merlin is scheduled for September 25th, with the product planned to be in US users' hands by September 28th at the latest. Another "Warp Teleseminar" has also been scheduled for that date by John W Thompson, head of the IBM Software Company.

One tester found only "one small problem" in the gamma release, instead of the multitudes in the beta. "I was not surprised to see how much cleaner the gamma was compared to the beta, said Brandon Allbery, senior programmer with Telotech Inc., in Beechwood, Ohio. "It has been working quite well as my primary work platform over the past several days. A few problems still remain. For example, testers said Merlin does not support a new NCR Corp. chip set in host bus adapters. Still, most agreed that the majority of bugs in the beta had been eliminated.

Multi-Processor Warp wins plaudits

A beta tester of the Warp Server SMP (Symmetric Multi-Processing) reports that "I have had such good performance running the beta that I am currently testing every application I can get hold of . It is the only operating system I have not been able to bring down very easily. It's flawless so far but, of course, I want more enhancements."

"Rumour has it that IBM may be developing a SMP module that could convert any OS/2 verion to SMP kernel. That or some Merlin features in Warp Server SMP would make my day!"

Fix Pack 22 wins approval

from a report on Compuserve

After two weeks, I can now safely say that FixPack 22 is so far the best of the fix packs released by IBM. After applying it to two seperate systems, neither machine has experienced a TRAP, hang, or lockup of any kind. My home system, which I keep up 24 hrs a day, 7 days a week, normally would lockup four or five times a week requiring a reboot.

Since applying FP22, I have yet to get a hang or lockup condition, and no traps whatsoever. And I BEAT on my home system, too! The office system is used primarily as a common communications point between the mainframe MVS/ESA system, the office Intranet (TCP/IP), and the office E-Mail system (NetBIOS). The home system is used for scanning, word processing, graphics work, communications, and GAMES GAMES GAMES.

Only problem? The color corruption problem in TD-Gammon introduced in FP17 is still unresolved, though the truncated characters in Vx-REXX appear to be fixed. However, the SYS3175 error in shutting down Vx-REXX is still not fixed, even though I reported this problem way back when I first installed FP17, and IBM sent me a SOM.DLL that corrected the problem. Why that fixed SOM.DLL is not in FP22 is beyond me.

Fix Pack 22 can be obtained from IBM, or from the [EurOS/2 web site].

The Java Earthquake

Robin Bloor of Bloor Research predicts that "the thin client will eat about 50% of the total PC market and about 70% of the corporate market". According to Bloor Research, Java is the centre of an "earthquake" that heralds a return to centralised or "server-centric" computing.

Bloor's predictions are based on inexpensive "thin clients" such as Larry Ellison's Network Computer taking market share as client computing devices, while servers grow in power with greater use made of massively parallel processing (MPP) technology. The impact on vendors is expected to be apparent by autumn 1997, when the PC market will begin to decline.

"Java has removed the PC and server lock-in. Soon the whole gamut of PC applications will be available in Java. The browser will become the PC desktop operating system". This will result in a decline in the importance of systems such as Windows 95 and OS/2. Bloor claims that the web browser breaks the de facto monopoly of Windows applications, and that the "Java HTML approach will gradually evict the current approach to client/server because of the economies it deliver".

At the same time, Nick Davis, brand manager for operating systems at IBM, says that Merlin's built in Java engine will allow application icons residing on the Internet or an intranet to be dragged onto the Merlin desktop, from where they will be run using Merlin's Java engine, rather than as an applet within a browser. Davis claims Merlin provides a more resilient platform for running Java applications than using a browser. He emphasises the reputation OS/2 has for performance and robustness.

It appears that IBM is expecting Bloor's predictions to be fulfilled, with the next generation of PC applications based on Java, releasing users from the hegemony of Windows. Nick Davis suggests that software will come in boxes with "Written in Java" rather than "Compatible with Windows" and that this will make OS/2 Merlin the platform of choice. IBM already claims to have a 15% corporate market share with OS/2 and up to 30% in the UK's financial sector.

OS/2 News

In the US, it is claimed that OS/2 has emerged as industry leader in the retail banking arena. Mentis Corporation, a leading research firm for the banking industry, says that OS/2 has increased its overall client operating system marketshare among large banks from nine percent in 1994 to a projected 25 percent in 1996. This compares to only seven percent for Windows/NT in 1994 and a projected nine percent in 1996. In addition, OS/2 has maintained over the past two years approximately one third of the marketshare in all large US banks for its server operating systems, compared to the 13 percent held by Windows/NT. Within the community banking sector, OS/2 marketshare for clients and servers has more than tripled, with Windows/NT penetration declining dramatically.

Netscape has committed to providing a native OS/2 version of its Navigator web browser. The initial implementation will be at the 2.x level, but unofficial comment suggests that the forthcoming version 4 will be brought to OS/2 along with other major platforms. IBM is evidently lining up with Netscape for its OS/2 browsing facilities, seeking to establish a broad front to combat the incursions of Microsoft's Internet Explorer. For the moment, Netscape Navigator is firmly in control of its position as the leading browser. Details of the IBM - Netscape announcement for OS/2 are obtainable via the Web links section.

Users of Version 1.1 of LinkRight can get an upgrade to Version 2.0 for $29.95 plus $5.00 shipping and handling. You can order by email or FAX. Further details from +1-(301) 762-1185 (fax) or Jeff Tremble <>.

Sysbench is a benchmarking program for OS/2. You can find the latest version on where it will be moved into the /os2/wpsutil directory. This is a bug fix version of the current 0.9.1a and 0.9.1 versions.

Mount Vernon, WA, August 19, 1996 - Perez Computing has released Ctrl-Alt-Del Commander v. 1.5, a $29 utility for OS/2 Warp that defends against desktop and application freeze-ups. It takes control of the boot services of an OS/2 Warp system, and prevents accidental rebooting of OS/2 from within any type of OS/2, DOS, or Windows session. In addition, it also allows "rebooting" of the Workplace shell without stopping any running applications. It gives complete command over all application's status (including their priorities), and allows selective shutdown of errant applications which cannot normally be shutdown via OS/2's Ctrl-ESC key sequence. It also provides a handy status line and enhanced task list to let you control applications from your PM Desktop. Finally, it includes a Game Boost option for DOS and Win full screen games to enhance their performance under OS/2.

At the August "Object World" show, IBM and Sun announced a scheme to consolidate their CORBA-compliant object request brokers. The partnership calls for the merger of IBM's SOM & DSOM and Sunsofts's Neo through the Internet InterORB Protocol (IIOP). The companies will seek to create a common code base. IBM will license its' MQSeries middleware to Sun, and Sun will license its' Joe Java-to-Neo middleware to IBM. Another highlight of the show was a deal between Next Software and Iona Technologies to combine technologies and incorporate the IIOP standards into future products.

CUPERTINO, CA, August 20, 1996 ... IBM and Sun Microsystems, Inc. today announced an agreement to integrate technology developed by IBM's wholly owned subsidiary, Taligent Inc., into the Java** development environment. The Taligent class libraries, which implement key components of the Unicode** international character set, will enable developers to create global applications and applets in Java. Using the class libraries' interfaces, Java applets and applications can recognize and respond to different languages and individual country requirements automatically. These libraries adapt dates, currencies, numbers and text to fit respective countries' formats. For example, a German developer working with Java will be able to represent currency in Deutschmarks and dates in German formats, while Japanese programmers can work with the information in their native formats.
