automatic-recovery

false

(optional) If true, the server instance attempts transaction recovery during startup.

timeout-in-seconds

0

(optional) Specifies the amount of time after which the transaction is aborted. If set to 0, the transaction never times out.

tx-log-dir

directory specified by the log-root attribute of the domain element

(optional) Specifies the parent directory of the transaction log directory instance-name/tx. The directory in which the transaction logs are kept must be writable by the user account under which the server runs. A relative path is relative to the log-root attribute of the domain element.

heuristic-decision

rollback

(optional) If the outcome of a distributed transaction cannot be determined because other participants are unreachable, this property determines the outcome. Allowed values are rollback and commit.

retry-timeout-in-seconds

600

(optional) Determines the retry time in the following scenarios: 

• At the transaction recovery time, if resources are unreachable.

• If there are any transient exceptions in the second phase of a two phase commit protocol.

  A negative value specifies infinite retries. A value of 0 (zero) specifies no retries. A positive value indicates the time after which a retry is attempted.

keypoint-interval

65536 (64 K)

(optional) Specifies the number of transactions between keypoint operations in the log. Keypoint operations reduce the size of the transaction log file by compressing it. A larger value for this attribute results in a larger transaction log file, but fewer keypoint operations and potentially better performance. A smaller value results in smaller log files, but slightly reduced performance due to the greater frequency of keypoint operations.
