Chapter 1 Jaguar Configuration

Using the OTS Transaction Monitor

You can monitor and administer transactions on a single Jaguar server from Jaguar Manager. You must be connected to the Jaguar server before you can monitor or administer it.

To administer OTS/XA transactions:

Select OTS Transaction Viewer for a server. The dialog displays the following information for all incomplete transactions. Because the OTS Transaction Viewer captures the information about incomplete transactions at a particular moment, you need to refresh the OTS Transaction Viewer to see any changes in the incomplete transaction status or any changes that you have made directly in the OTS Transaction Viewer.

Transaction ID The local identifier associated with the transaction on a specific server.
Family ID The identifier of the root transaction that this transaction belongs to.
Because Jaguar does not support nested transactions, the Family ID is the same as the Transaction ID.

State Describes the status of the transaction and can be:

State	Description
local_state_active	The transaction is currently active in the server.
local_state_inactive	The transaction is not currently active in the server.
local_state_preparing	The transaction is in the process of being prepared.
local_state_prepared	The transaction has been prepared.
local_state_committing	The transaction is in the process of being committed.
local_state_committed	The transaction has been committed.
local_state_commit_complete	The transaction has committed and all participants have been informed, but the outcome may not have been reported to the transaction originator. For example, there may have been heuristic outcomes.
local_state_before_abort	The transaction has rolled back but has not yet started the rollback process.
local_state_aborting	The transaction is in the process of rolling back.
local_state_aborted	The transaction has been rolled back.
local_state_abort_complete	The transaction has rolled back and all participants have been informed, but the outcome may not have been reported to the transaction originator. For example, there may have been heuristic outcomes.
local_state_finished	The transaction has completed.
local_state_none	The server knows about the transaction, but the server is not a participant in the transaction.
local_state_present	The transaction is active in the server but is not yet a participant in the transaction.

You can execute Rollback only on transactions that are not yet in the prepared state. You can execute all other operations only on transactions that have been prepared.

Lock Holder The transaction that holds the lock.
Lock Waiter The transaction that is waiting for a lock to be released.
Level An integer that represents the level of a nested transaction. Since Jaguar does not support nested transactions, this field is always 1.

In the dialog that displays, select a transaction and click one of these buttons:
- Refresh List Refresh the list of all unfinished transactions.
- Rollback Roll back the entire transaction, including any sub-transactions.
  Jaguar does not currently support nested OTS/XA transactions (also called subtransactions).
- Force Complete Force the transaction's rollback or commit processing (whichever outcome the transaction coordinator determined for the transaction) to be completed.
- Heuristic Commit Perform a heuristic commit.
- Heuristic Rollback Perform a heuristic rollback.
- Global Info Displays the global transaction identifier and the identifier of the application that started the transaction.
