APPN

[Guest.Visitor]

My company have two Ethernet line. One is for passthru and QSNADS. The other is for mirroring. The system QCMNARB1 is creating a device under the first line with device name is the same as the one on mirroring with extension 00 at end. It also happens for device on the first line create on the second line. For example, LINE1 CTL1 DEV1 DEV200 LINE2 CTL2 DEV2 DEV100 Can anyone know why and explain ? Is there any PTF as well? Thanks Edgar Maung

Edgar, Your consternation has to do with the protocol, APPC/APPN and SNADS. You have a table configured for remote systems. This table defines paths to other machines. It is also associated with Modes of Service, Classes of Service, and other features, all part of OS/400. When you trigger a SNADS transmission, SNADS asks for the quickest path to the target. APPC/APPN figures out what the quickest hops are. APPC will cause automatic creation of a device to handle the transmission for the Controller handling the path. If APPC sees a device with the name it wants to use, it appends a number to it's new device name. You can see DEVD, DEVD00, DEVD01, DEVD02, etc. If this is really causing a problem look in the *APPNRMT table (WRKCFGL *APPNRMT) and delete or correct the paths. Hope this helps. Happy holidays.
