This offers multiple advantages. For one, it gives you the ability to Web-enable an existing legacy app without changing that app. Yet another, not-so-obvious advantage is being able to write new apps solely for Web invocation without requiring Web knowledge on the part of the programmer. Read more about the advantages in this tip. >> CLICK for the full tip: http://www.search390.com/tip/1,289483,sid10_gci856854,00.html Got a CICS tip of your own?

What is the easiest way to create a similar (same external look) user interface through the Web? We don't want to use TN3270 emulation. >> CLICK for Jim's expert response: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid494310_tax285032,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ROLL YOUR OWN SCRIPTING -- USE LUA | by Jim Keohane Jim Keohane points out the advantage of a scripting facility within CICS (or on the same host as CICS) to reduce ping-ponging between host and Web app for multiple COMMAREA or screen interactions, to allow for rapid prototyping and ad hoc usage, to simplify Web access to the back end without too much of a CPU penalty and, best of all, to underwrite Jim's "play time." >> CLICK for full tip: http://search390.techtarget.com/tip/1,289483,sid10_gci833537,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= HELP WITH STRINGS CONSIDERATIONS FOR ESDS FILES? | by Robert Harris Dear Ask the Expert, I read in the CICS Performance Guide that "there are some special performance considerations when choosing a STRINGS value for an ESDS file. If an ESDS is used as an 'add-only' file (that is, it is used only in write mode to add records to the end of the file), a string number of 1 is strongly recommended. Any string number greater than 1 can significantly affect performance because of exclusive control conflicts that occur when more than one task attempts to write to the ESDS at the same time." Would you be able to elaborate on the principle behind this statement? >> CLICK for Robert's expert response: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid495634_tax289214,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= SEARCH390 DISCUSSION FORUMS | Developer Search390.com user "Samaga" posted the following in the Developer forum and received some advice from Jim Keohane: "We can implement MQ Series in CICS, but can we do MQ Messaging/Notifications in TSO through batch jobs? If yes, is there any difference in the implementation when compared to CICS? Can we call MQPUT1 from both CICS and batch?" >> CLICK to post a response or to read the full discussion: http://search390.discussions.techtarget.com/WebX?[EMAIL PROTECTED]@.ee83ff7/619 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= TAKE OUR POLL | Search390 What's the biggest advantage of upgrading to z/OS? >> CLICK to post your response: http://search390.techtarget.com/poll ____________________________________________________________________ ::::::::::::::::::::: SEARCH390 CONTACTS ::::::::::::::::::::::::::: BJ RAMA, Site Editor (mailto:[EMAIL PROTECTED]) >> Send us your original articles and best practices.
