If you receive a BBOT00xxW message, you must use
RRS panels to view the outcome of other branches in the transaction
and set the outcomes of InDoubt units to match the outcome of those
other branches.
Before you begin
When a BBOT00
xxW message is displayed, there is a possibility
of an heuristic outcome. See
z/OS® MVS™ Programming:
Resource Recovery for more information on how to use the RRS
panels and what administrative access (RACF® access
to the facility class, for example) is needed to resolve URs and remove
interests.
About this task
Perform the following steps to remove an expression of
interest in this UR if you receive any of the following error messages:
- Messages BBOT0019W and BBOT0020W, which appear together, indicate
that this server could not determine the outcome from its superior.
Message BBOT0020W, describes the resource to which the product could
not provide an outcome.
- Message BBOT0021W, which indicates that a server has determined
the transaction outcome but has not been able to communicate it to
its subordinates.
- Message BBOT0022W, which indicates that the transaction outcome
was determined and communicated to the subordinate, but the subordinate
resource has not been "forgotten".
Procedure
- Select option 3, Display/Update RRS Unit of
Recovery information on the main RRS panel.
- To view the details of this URID, enter it in the URID
Pattern field on the query panel. Press the Enter key
to execute the query. The query results should display
the UR. Take note of whether the state of this UR is InCommit, InBackout
or InForget. In the column labeled S, enter v to
display the details for this UR.
- Remove the OTS interest. The RRS Unit of Recovery
Details panel opens. Near the bottom of the panel, find the Expressions
of Interest heading. This heading is followed by one or more rows
that represent each individual expression of interest in this UR.
Complete these steps to remove the OTS interest:
- Find the row that represents the OTS interest. This
row will have an RM name in the form of BSS00.xxx.yyy.IBM,
where xxx is the system to which the server was configured
and yyy is the specific server name.
- Type r in the column labeled S to indicate
that you want to remove this interest.
- Press the Enter key to execute the query.
- Press the Enter key to confirm the removal of this
interest. The RRS Remove Interest Confirmation panel opens.
The RM name and UR identifier fields are pre-filled. Press the Enter key
to confirm the removal of this interest.
Results
You know you are done when RRS marks the subordinate server
as restart anywhere. Determine this by choosing option 1 under Browse
and RRS log stream, and then choosing sub-option 4 under RRS Resource
Manager Data log.
What to do next
Any subordinate nodes that restart and ask this server about
this UR can not obtain this information. If you restart the server
containing these nodes, they might be assigned an outcome that is
different from the outcome of the transaction. You must manually resolve
these nodes before you bring up the servers and start the server for
which you just released the UR.
