IN XA/PURESCALE ENVIRONMENT, XA-END COULD BE BROADCASTED TO ALL NODES EVEN IF THEY WEREN'T PART OF THE TRANSACTION.

| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
In XA/Purescale environment, XA-END could be broadcasted to
all nodes even if they weren't part of the transaction.
When running multiple XA-transactions under the same
connection to the database, if one transaction does some remote
processing because of
1. DDL
2. implicit rebind/recreate/regenration of package/procedure
when invoking a package/function/procedure.
the remote nodes visited in this transaction could be used for
all subsequent transactions under the same connection.
This sends multiple unnecessary XA-END interrupts to remote
nodes.
During this issue reproduction, we can see the following
