CESL - sign-on long

Use CESL to sign on to CICS® using a password or a password phrase or similar authenticator.

The CESL transaction can be used as a 3270 transaction from a 3270 terminal or as a single-line command from both 3270 and non-3270 devices. This section describes the 3270 transaction. For information about the line command, see .

CESL supports sign-on with a password phrase of 9- to 100-characters or with a standard password of up to 8 characters. If a user enters a password that is 9- to 100-characters, CESL treats the password as a password phrase. In other respects, CESL operates in the same way as the CESN sign-on transaction. CESN does not support password phrases but you can specify CESN as an alias for CESL. See Changing CESN to permit password phrases for more information about how to create an alias for CESL.

The CESL sign-on transaction displays a BMS map. The transaction is pseudo-conversational and uses the EXEC CICS SIGNON command. For details of the parameters on the BMS map, see SIGNON.

Notes:
  1. If a user signs on at a terminal that is already signed on, CESL signs off the previous user. However, it does not happen unless the user completes the CESL panel before pressing ENTER.
  2. Ensure that the PROFILE for the sign-on transaction CESL specifies UCTRAN(NO). This is the value for the CICS-supplied definitions. Otherwise, passwords and password phrases are converted to uppercase.
  3. CICS saves the value of the UCTRAN option for the terminal and temporarily sets it to UCTRAN(NO) while the user is prompted to enter credentials. The user ID and other parameters are always translated into uppercase but the password remains in the case entered by the user. When the CESL transaction completes, the UCTRAN attribute is restored to its original value. If the user disconnects from the terminal before the transaction is completed, the terminal might be left with the UCTRAN(NO) attribute set.
  4. If the old password expires, this dialog prompts for a new password. The password can also be changed before it expires.
  5. Do not use a standards password as authorization to enter a new password phrase. Do not use a password phrase to authorize a new standard password.
  6. Autoinstall of BMS maps is not carried out within the CESL transaction. When CESL tries to send out any BMS map that is not installed, CESL sends out the English BMS map.
  7. You can customize the CESL map set only if you do not change the format of the symbolic map set. The source for the CESL map is included in map set DFHSNLE in the SDFHSAMP library. After customization, regenerate the physical map sets in the usual way into a load library, which must be included in your DFHRPL concatenation in front of the CICS libraries. For more information, see Basic mapping support.
  8. The 40 x 12 map does not support password phrases.
  9. Unsuccessful sign-on and sign-off errors cause DFHCEnnnn messages to be issued.
  10. RACF OIDCARD users can use CESL to sign on if the card reader supports the DFHOPID attention identifier (AID). If it does not, you will need to write your own sign-on program using the EXEC CICS SIGNON command. For programming information, see SIGNON.
