  1. CICS and TSO What you need to know

  2. CICS • Customer Information Control System (CICS) is a software package designed by IBM to allow computerized storage and retrieval of information. • A great deal of the information stored in CICS is confidential and access to this information is restricted through the use of USERIDs and Passwords. • Access to CICS is given on a need-to-know basis. Not everyone has access to CICS and those that do are not necessarily granted access to all the information stored in CICS.

  3. Your Responsibilities • Since students do not have access to CICS, we are not expected to troubleshoot and solve problems within the CICS system itself. • We do, however, need to insure that the customer is a valid OU faculty or staff member AND that they are able to connect to both the domain controller and the internet (basic network troubleshooting applies here) • A walkthrough of your CICS/TSO responsibilities will be covered later.

  4. CICS Passwords • Passwords must be 5-8 characters • Passwords must begin with an alphabetic character • Passwords will automatically expire after 90 days and can never be reused. • E.g. a customer cannot even reuse a password they selected back in 1994 even though they would have been through over 32 different passwords

  5. Connecting to CICS • There are two ways to connect to CICS • Through Host On Demand • Through the SNA servers

  6. Host On Demand (HOD) • HOD is a TCP/IP solution to connecting to CICS. It is just as secure as the SNA servers but it is not limited to the number of connections. • Since an LU is not required, IT can grant as many people as need access the ability to connect to CICS

  7. HOD (continued) • HOD can be installed from this link: http://infoserv.ou.edu/it/mainframe/hod/index.cfm after clicking on the online instructions. • Everyone in the Helpdesk should get experience installing HOD at least one time so as to be able to walk a customer correctly through the process.

  8. SNA Servers • These are servers with a finite number of connections over a coaxial lines. There are several SNA servers IT maintains. • Connecting requires an LU (unique identifier) of which there are a finite number. • IT is moving away from using SNA servers and is directing new users to Host on Demand.

  9. Helping the User If a user is having trouble accessing CICS/TSO, ask them if they are able to see the interlocking OU. If they are not getting this far, ask how they are access CICS/TSO. Options include, SNA, HOD, or Cellview for Macs.

  10. Helping the User (cont’d) • Verify they are using their CICS ID, not their 4x4 (all CICS ID’s begin with a “C”). • If they get user ID revoked or invalid password message, transfer them to either Colleen Cowin or Sherol Robertson.

  11. Helping the User (CICS) At this point IT should be able to turn over specific functions to the customer’s area where they should have some resources available to use the data processing functions of the mainframe.

  12. Helping the User (CICS) This screen indicates the customer has successfully logged onto CICS. From this point, they need to contact their supervisor for proper CICS usage. For the customers that are using CICS for the student information systems on campus, there is a PDF file located at this sight: http://www.ou.edu/admrec/cicsindex.htm.

  13. Helping the User (TSO) The next screen that appears after the OU screen is the password screen. This includes their user id (supplied from the last screen), their current password, their logon procedure their project code (account number), and the next common parameter is the new password field.

  14. Helping the User (TSO) The first screen after signing on to TSO is the READY prompt. Most development done in TSO is performed in ISPF a screen driven facility designed to write, run and debug programs as well as several other job related functions that staff, faculty and researchers need the mainframe’s computing power and storage.

  15. Helping the User (TSO) At this point IT should be able to turn over specific functions to the customer’s area where they should have some resources available to use the data processing functions of the mainframe.
