Graphic Configuration Errors
3270
You may encounter the following graphical errors:
- Message: ADM0275 E GRAPHICS CANNOT BE SHOWN
Several factors can cause this GDDM error message when attempting to display graphics. Check each of the following items carefully in the order listed and take corrective action:
- The host (VTAM) logmode you are using must be a queriable logmode. By default, your host LU is assigned a logmode which defines screen size and queriability features. If you have a non-queriable logmode, HostExplorer cannot display the graphics. Check with your VTAM systems programmer if you think your logmode is not defined as queriable; tell them that the PSERVIC parameter must start with '028' or '02C'.
- If your host uses a session manager such as CA-Supersession or TPX, the session manager must be configured such that device query is supported. Otherwise, HostExplorer cannot display the graphics because all host graphics applications perform a device query before sending its graphics data.
