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 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

2048

(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 (for example, 4096) results in a larger transaction log file, but fewer keypoint operations and potentially better performance. A smaller value (for example, 100) results in smaller log files, but slightly reduced performance due to the greater frequency of keypoint operations.
