Several AS/400 configuration objects are required to attach an APPC connection via a twinaxial controller. You must have the authority to manage AS/400 configuration objects. A summary of the objects:

        Sample Oject name   type        description

    (1)     CTL01           *CTL ----   Twinax workstation controller
    (2)         DSP010405   *DEV 5150   twinax front end for APPC connection

    (3) QTDL8258000         *LIN *TDLC  Twinax DLC line description
    (4)     STEVE           *CTL *APPC  APPC controller for PC location
    (5)         STEVE       *DEV *APPC  APPC device for PC location

    (6)     QVIRCD0001      *CTL *VWS   Virtual workstation controller 1
    (7)         STEVES1     *DEV 3197   virtual display device 1
    (8)         STEVES2     *DEV 3197   virtual display device 2
    (9)         STEVES3     *DEV 3812   virtual printer device 3

The names of the devices will no doubt be different for your system. Some are common and support many APPC devices, some are specific to just a single twinax APPC connection. A more detailed description of the AS/400 objects follow:

(1)     CTL01           *ctl        Twinax controller

This controller name defaults to CTL01 and an AS/400 can can contain several workstation controllers (twinax and other such as Async controllers). This controller may be one of several controller model types.

DO NOT DELETE this controller description as it likely supports many other devices.

(2)         DSP010405   *dev 5150   twinax front end for APPC connection

This device description forwards the APPC conversation from the twinax controller (CTL01 in this example) to the QTDL... APPC twinax line description. The name of this object depends on several variables. If the system builds the object then it will follow the guidelines set in the system values (see command WRKSYSVAL *SYSCTL value QDEVNAMING). This object can be created manually and then the name can be almost any value.

This object is specific to a single twinax location and should be deleted if the station is being reconfigured either in type or in APPC location name (also called control point name).

You can use the PRTDEVADR command with the appropriate twinax controller name (see object (1)) to list all attached device names and types. This command will generate a report you may print or view on the print spool (with the DSPOUTQ command or the WRKSPLF command).

You can use the WRKDEVD DSP010405 command (with your object name in place of parameter one) to delete the object, or use the WRKSYSSTS *DEV DSP010405 command to view the object status. When in the WRKSYSSTS command use option 2 to vary off the object (assuming it is not active at the time) and option 8 to work with the object description where you may use option 4 to remove/delete the object. You can also use the command WRKSYSSTS *CTL CTL01 to display the controller and all attached devices to manage the description.

(3) QTDL8258000         *lin *TDLC  Twinax DLC line description

This line description manages all Twinax Data Link Control (TDLC) communications. The AS/400 builds this object and depending on the volume of objects on your system, you may have more than one of these objects.

DO NOT DELETE this controller description as it likely supports many other controllers and devices.

(4)     STEVE           *ctl *APPC  APPC controller for PC location

This APPC controller is built by the AS/400 specifically for the twinax location. The name defaults to the same as the PC location name (also known as PC control point name). This oject may also exist with a 00 or 01 suffix appended to the end of the name. If this occurs it is suggested that all variations of the object be deleted.

This object is specific to a single twinax location and should be deleted if the station is being reconfigured either in type or in APPC location name (also called control point name).

You can use the WRKCTLD STEVE* command (with your object name in place of parameter one) to delete the object, or use the WRKSYSSTS *CTL STEVE* command to view the object status. When in the WRKSYSSTS command use option 2 to vary off the object (assuming it is not active at the time) and option 8 to work with the object description where you may use option 4 to remove/delete the object. You can also use the command WRKSYSSTS *LIN QTDL* to display the line, controller and all attached devices to manage the object. You will have to vary off the QTDL* line description before you can delete the controller description which will temporarly shut down all other APPC stations attached to that line.

(5)         STEVE       *dev *APPC  APPC device for PC location

Similar to the APPC controller, the APPC device is built by the AS/400 specifically for the twinax location. The name defaults to the same as the PC location name (also known as PC control point name). This oject may also exist with a 00 or 01 suffix appended to the end of the name. The device description with a suffice of S1-S9, T1-T9, U1-U9 are virtual devices described later. If the (00 suffix) occurs it is suggested that all variations of the object be deleted.

This object is specific to a single twinax location and should be deleted if the station is being reconfigured either in type or in APPC location name (also called control point name).

You can use the WRKDEVD STEVE* command (with your object name in place of parameter one) to delete the object, or use the WRKSYSSTS *DEV STEVE* command to view the object status. When in the WRKSYSSTS command use option 2 to vary off the object (assuming it is not active at the time) and option 8 to work with the object description where you may use option 4 to remove/delete the object. You can also use the command WRKSYSSTS *LIN QTDL* to display the line, controller and all attached devices to manage the object. You will have to vary off the QTDL* line description and APPC controller before you can delete the device description.

(6)     QVIRCD0001      *ctl *vws   Virtual workstation controller 1

This controller description manages virtual workstations (the display and printer devices you use). The AS/400 builds this object and depending on the volume of objects on your system, you may have more than one of these objects.

DO NOT DELETE this controller description as it likely supports many other devices.

(7)         STEVES1     *dev 3197   virtual display device 1

The virtual devices are created automatically by the AS/400 when you establish a display or printer session with the AS/400. They default to the name of the PC location name followed with a two character suffix (S1 - U9). However, the PC operator may configure a unique name in the WinAPPC configuration that may no match this naming scheme. This device is a workstation type/model, either display or printer, exact model depending on how the operator has configured the PC devices. There may be many (1 to 32) of these descriptions.

While this object is specific to a single twinax location it need not be deleted unless it is no longer to be used. The AS/400 will automatically recreate the object if it is deleted.

You can use the WRKDEVD STEVE* command (with your object name in place of parameter one) to delete the object, or use the WRKSYSSTS *DEV STEVE* command to view the object status. When in the WRKSYSSTS command use option 2 to vary off the object (assuming it is not active at the time) and option 8 to work with the object description where you may use option 4 to remove/delete the object. You can also use the command WRKSYSSTS *CTL QVIR* to display the controller and all attached devices to manage the object. You will have to vary off the QVIR* controller description before you can delete the device description.

In summary if you are moving the location of a twinax APPC station on the twinax controller (either port or address 0-6) or changing the PC location name (aka PC control point name) you should delete the 5150 device attached to the twinax workstation controller and the APPC controller and description specific to that PC location. All other objects can remain on the system. If the PC station is no longer going to be used, then the virtual devices may also be deleted to reduce AS/400 clutter. You must have *IOSYSCFG authority on the AS/400 in order to perform these operation.

If you have any specific questions or are in doubt on whether you should delete an object - ASK SOMEONE FIRST. Either call your AS/400 system administrator or your Synapse technical support represenative.
