Manage active and prepared transactions

Use this task to manage active and prepared transactions that might need administrator action.

Overview

Note: If you choose to complete a transaction on an application server, it is recorded as having completed in the transaction service logs for that server, so will not be eligible for recovery during server start up. If you complete a transaction, you are responsible for cleaning up any in-doubt transactions on the resource managers affected. You can use the administrative console to display a snapshot of all the transactions in an application server that are in the following states:

Manual transactions

Transactions awaiting administrative completion. For each transaction, the local id or global id is displayed. You can choose to display information on each resource (specifically, which resource manager it is associated with) associated with the transaction. You can also choose to commit or rollback transactions in this state.

Retry transactions

Transactions with some resources being retried. For each transaction, the local id or global id is displayed, and whether the transaction is committing or rolling back. You can choose to display information on each resource (specifically, which resource manager it is associated with) associated with the transaction. You can also choose to finish (abandon retrying) transactions in this state.

Heuristic transactions

Transactions that have completed heuristically. For each transaction, the local id or global id and the heuristic outcome is displayed. You can choose to display information on each resource (specifically, which resource manager it is associated with) associated with the transaction. You can also choose to clear the transaction from the list.

Imported prepared transactions

Transactions that have been imported and prepared but not yet committed. For each transaction, the local id or global id is displayed. You can choose to display information on each resource (specifically, which resource manager it is associated with) associated with the transaction. You can also choose to commit or rollback transactions in this state.

To manage the active and prepared transactions for an application server, use the administrative console to complete the following steps:
