SHow -APPN TreeCache [COS name]

No default

Description

The TreeCache parameter displays the Topology and Route Selection tree cache for different classes of service. If you do not specify a COS name, the display shows all the SNA-defined COS tree caches.

The following is an example of the display obtained using the SHow -APPN TreeCache:

------------------------Network Node Tree Cache--------------------

Cached tree for COS #INTER ..

(0) node = US3COMHQ.CUBE (total wt = 60)

(1) node = US3COMHQ.CN5 (total_wt = 90)

(2) node = US3COMHQ.SPHERE (total_wt = 180)

(1) node = US3COMHQ.IBM4 (total_wt = 150)

The display shows the information regarding the route for the specific COS. The "total_wt" shown is the weight of the route to the corresponding node, including the weight of the node itself. The nodes are displayed in the order they are traversed on the route to the destination node.

Because the tree cache may not be cached if there is an ongoing session using a specific COS, you can force a tree cache calculation by performing an APpnPING to itself (the local node). For example, to obtain the tree cache for the COS #BATCH on local node US3COMHQ.LOCAL, enter:

ApnPING US3COMHQ.LOCAL Mode=#batch

After performing the ApnPING, display the tree cache for the COS #BATCH by entering:

SHow -APPN TreeCache #BATCH
