>Our Windows Server Team is looking for alternatives to our current Aviva solution. Other than using a different tn3270 client application. Does anyone have any suggestions or know of anything on z10's? > Not sure if the direction is to run this through an application which would use TN3270 (say CICS) and have it accessible using a Browser. In general HOD is just a 3270 emulator which requires the download of a small JAVA applet to the user's PC. Keep in mind all the emulators do the 3270 data stream conversion to HTML in the PC and HTML to 3270 DataStream. Thus some are called FAT-Clients or maybe HOD could be called a Skinny-Client but the conversion happens at the PC level. If all the users are internal, then it may not be a problem of loading software. If users are external, some do not appreciate their PC being updated with software.
In general there was a requirement for outside entities to access systems and the HATS product was chosen. There are samples included and in less than 3 weeks, there was a WEB-like application in production with the only requirement on the end user of having a Browser. If one uses HATS, you have to be running Websphere Application Server either on z/OS, zLinux, or Windows (maybe Linux on Intel). The backend 3270 screens stay the same and the HATS application runs as a JAVA Plug-in with WAS to do the conversion of the 3270 datastream to HTML. Another aspect to keep in mind is how these are development and the need to buy tools. Buying HATS gives you a number of copies of Rational Application Developer to be used exclusively for HATS development. Then one has to buy HIS (Host Information Services) licenses (consists of a license for a user to use HATS, HOD or PCOM). Buying say 500 licenses gets you 5 RAD for HATS development for free. In general there are other vendors software to do the same kind of things. I would definitely ask about having to buy the tools to develop the applications. In the end, the 3270 green screens have not been altered, the HATS screens appear to be a true WEBApp and 99% of the users do not know this is coming from the IBM Enterprise Server (mainframe app of old). In most cases, only the needed information has been taken from the green screen and presented on the web page along with logos, pulldowns, lists, etc. I am told if you can code WORD Style Sheets, then HATS is a breeze. Oh yes, in HATS 7.5 and the new RAD, you can send the green screen to a cellphone. RAD has the development area for ensuring the Webpage will fit onto a cellphone. Have yet to explore that aspect yet, although it sounds like in some cases a CICS application may be needed to interact with one of the users locally as they are riding home on the Metro train. jim ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
