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 BBOT00xxW 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.
