The other week, I decided to take the home wireless networking plunge.
My first step in the world of 802.11 was buying a wireless router. I began my search by looking around for sites that offer purchaser submitted reviews. Why? I value the assessment of someone like me, a marginally tech savvy person with limited needs.
For me, ease of setup, security and cost were the major criteria. I didn't care if my router would allow me to work 1,236 feet away at 42 Mbps because chances are I would only be a room away.
I recount this story because I would like to ask you for some mainframe tips. Who better to offer advice to mainframers than their brethren in the Big Iron foxhole? Have you upgraded to z/OS? Dabbled with Linux on the mainframe? Written CICS applications lately?
Now, some of you may doubt you have any worthwhile tips to submit. Here is another way of looking at it: imagine there is a new person working on the mainframe. What little pearls of wisdom would you tell him? What tricks have you learned that makes your job easier?
I am sure there are little tricks you use every day that others would find very helpful.
Click here to submit a tip. You can also send them directly to me, [EMAIL PROTECTED] Thanks.

Mainframe trivia mania

Mr. Know-IT-All is back with a new quiz, but he promises its shorter size does not mean it's easier. In fact, he intends this for mainframers who know IBM wasn't the only Big Iron maker in town. Did you know GE made mainframes long before it owned NBC? If you do, then this quiz is for you. Do you think you have what it takes? If so, take the quiz below. Good luck!

This Week: In the forums

A Search390.com user asked in our operating systems forum:
In our shop, branches send transactions to the IMS through LU 6.2, using APPC (that is, via SNA). The Web server does that in the same way (using SunLink). In that context, the client sends the USERID and the PASSWORD as part of the protocol (the FMH-5 header) to establish connection with mainframe. The APPC/MVS is able to handle this user id and Password and ask RACF to validate both. If RACF denies access, the client receives an error and the client Program is able to manage the error.
If the error is "password expired," the client program initiates a conversation with an SNA internal implementation service transaction program that maintains password on APPC/MVS ...
Now, we want to change our connectivity from SNA to TCP/IP, and have started to use IMS Connect to send the transactions to IMS, and IMS Connect is able to handle the password and User Id to talk with RACF to verify user and Password, but in case of "password expired," or just because of the user want to change the password there is not an equivalent mechanism to change the password using some equivalent program to the X'06F3F0F1' in the SNA world. IBM says that there is no standard method
and that there is no plan to develop it in near future, and that if we want to do that, we must "do it yourself" using the user Exits of IMS Connect and TCP/IP. Is there anybody with the same problem? How has been solved?
