Defining the devices in use

GDDM V3R2 Diagnosis
SC33-0870-01
GDDM supports a wide range of devices. It is important that you report the device environment accurately. You should report:
  • The device type and model
  • The controller type and model to which the device is attached
  • The device tokens, if used
  • The device definitions
  • The display type
  • The display adapter type
An application always has a primary device opened. This may be a real device, or a dummy device. If it is a real device, report its device type and model and those of the controller to which it is attached. If it is a dummy device, report the device token. The application has a dummy device if it is running in a batch environment or on a disconnected VM machine.
Some applications may use device tokens even though they have a real primary device. Report this.
The application may also have an alternate device open. If there is an alternate device and it has a device token associated with it, report this token.
If a device token supplied by GDDM is being used, report the token name. If a user-defined token is being used, you may be asked to give the definitions for it.
If the symptom is associated with a GDDM family-1 printer, report the LU type of the printer.
On some subsystems, the device definitions to the subsystem or telecommunication access method are important:
  • If TSO is being used, report the PSERVIC.
  • If the GDDM/TSO Print Utility is being used, report the PSERVIC.
  • If IMS is being used, report the device token being used by the system definition database.
  • If CICS is being used, report the feature operands in the DFHTCT macro.
  • If GDDM-PCLK is being used, report the following:
    • the emulator in use
    • the emulator level
    • the definitions on the GDDM-PCLK setup panels
  • If GDDM-OS/2 Link is being used, report the following:
    • the OS/2 version - run SYSLEVEL from an OS/2 session
    • the GQFLEVEL information - run GQFLEVEL from an OS/2 session
    • the CSD level information - run SYSLEVEL from an OS/2 session
    • a copy of the CONFIG.SYS file
    • what national language you are using
