AUTO; WRITE and AUTO; WRITE&CLEAR
A closed cycle is formed if this chain tries to include the same System more than once; that
is, a sending System (waiting for acknowledgment) is itself sent an Automatic Entry as part
of the same transaction. That System would never be able to handle the incoming
transaction, as it will never receive the acknowledgment it is waiting for.
For example, suppose your System A sends an external Automatic Entry to System B,
which needs to send an external Automatic Entry to System C before the transaction is
complete. If System C then tries to send an external Automatic Entry to System A as part
of this transaction, you have attempted to create a closed cycle, and the attempted
external Automatic Entry from System C will receive this error notification.
For OLTP Automatic Entries
For OLTP Automatic Entries, the following table shows the values of GLB.HUBSTATUS
when GLB.STATUS is five asterisks (*****).
