TclPro1.1 comes with a 107-page User's Guide in both hard- and soft-copy formats. The soft copy is in PDF format and requires the Acrobat 3.0+ viewer. Local on-line documentation also includes browser-based help and man pages. Additional information, resources and links are available at http://www.scriptics.com/resources/.
I compared a couple of the User's Guide chapters with the browser's help content. The User's Guide and the local browser-based help content are similar in some respects and also contain some differences. One primary difference is the availability of message IDs within the on-line help.
I did notice a couple of minor things about the browser-based on-line help. The on-line “Using TclPro Checker” topic referred to a nonexistent example. I did find the same topic and example in the User's Guide. On the other hand, I attempted to use an example command from the book and it failed. The command usage error messages and the on-line help quickly pointed out the book's error.
At the time of this writing, Scriptics' web site and other literature indicated TclPro is licensed to a named individual and not the platform. No clear indication was given as to how licenses could be reallocated within an organization if a personnel turnover were to occur. Licensing relief may be on the horizon. The next release of TclPro will offer a UNIX-based network license package. A five-user license will be the smallest available network license.
A 30-day e-mail installation and evaluation support service is included. As mentioned above, my experience with this support was quite positive. Scriptics also offers three levels of fee-based support. The lowest level is an annual product update service. This level of support provides only product updates. The two other levels of support, Gold and Platinum, go beyond product updates and are sold on a per-user basis. At the time of this review, the product update service is a prerequisite for either the Gold or Platinum support levels—not an unreasonable condition. I feel some of the other conditions on support need to be rethought. For example, the Gold-level support required purchasing support for a minimum of five users. This is rather expensive if you own only one or two licenses.
I was unable to find recommended minimum system requirements in the documentation or on the web site. This product's command-line tools run on a 486/66 platform with 24MB of RAM. I do not recommend running the debugger on this class machine unless you do not mind waiting several minutes. TclPro1.1 runs quite nicely on a 300MHz Pentium II with 64MB of RAM.
I found TclPro Version 1.1 easy to learn and found value in each of the four TclPro tools. I feel the product is definitely worth the download and evaluation. The User's Guide very adeptly describes TclPro: “TclPro is an evolving piece of software. We will continually improve TclPro according to the user feedback and the needs of the Tcl community.” Let Scriptics know if it does not meet your needs.
Note that a beta release of TclPro Version 1.2 was made available shortly before this article was submitted for publication.

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
