Technical Tips

End-user gets GD024, and job log shows associated GC136 error messages in CBEEDITP

This is generally an indication of a problem with a 3270 emulator passing Invalid 3270 data to PHOENIX/PREFERENCE. There is a special case for CICS terminal sessions on PREFERENCE where the user can trigger this error condition from a problem 3270 emulator. This can occur if the user presses the help request key multiple times before the Help screen is displayed.

We cannot work around the problem with the 3270 emulator. However, it is possible to to address one of the underlying conditions that causes the user to repeatedly press the help request key ..

Slow help key response time may be due to CICS having a higher dispatching priority than PREFERENCE. This condition will allow CICS users to queue requests to PREFERENCE faster than PREFERENCE can process them. To address this issue we recommend the following:

• check to see what the dispatching priority is for your PREFERENCE Region
• check to see what the dispatching priority is for each of the CICS Regions that communicate with PREFERENCE.
• compare the PREFERENCE Region dispatching priority to each of the selected CICS Regions.
• The dispatching priority of PREFERENCE must be at least as high as these CICS Regions.
• If PREFERENCE processing is slower for users connected through CICS, then you may want to consider setting the PREFERENCE priority a bit higher than CICS.
