STORAGE SHORTAGE IN structure_name - UNABLE TO RECONNECT

Explanation

This message is issued when VTAM® is attempting to reconnect to a coupling facility structure. A storage shortage in the structure was detected before attempting to reconnect. A storage shortage is defined as one or more of the following:
  • 80% or greater of list entries are being used.
  • 80% or greater of list elements are being used.

Before VTAM will connect to the structure, the storage problem must be corrected.

structure_name is the name of the MVS™ coupling facility structure.

System action

VTAM will remain disconnected from the coupling facility structure until the storage usage drops below 80%.

Operator response

Issue D NET,STATS,TYPE=CFS,STRNAME=structure_name to display the storage utilization of structure_name.

If either entry or element utilization is greater than 80%, start a rebuild using the SETXCF START,REBUILD command. This will cause VTAM to adjust the number of entries and elements in use. See the z/OS Communications Server: SNA Network Implementation Guide for more information about the SETXCF command.

If the rebuild does not relieve the storage shortage, the size of the structure will need to be increased. See the z/OS Communications Server: SNA Network Implementation Guide for information about how to adjust the size in the case of a storage shortage.

To force VTAM to reconnect to the structure regardless of storage utilization, issue the V NET,CFS,ACTION=CONNECT command.

System programmer response

None.
