Transaction Status Manager Service

[janeg]

Hi please could someone point me where I can find some documentation explaining what the transaction status manager service does

and when out of process recovery is required

[mmusgrov]

It is referenced in the failure recovery guide: http://docs.jboss.org/jbosstm/4.17.2.Final/guides/arjunacore-failure_recovery_guide/index.html

An attempt, by the RecoveryManager, to recover a transaction that is still progressing in the original

process(es) is likely to break the consistency. Accordingly, the recovery modules use a mechanism

(implemented in the com.arjuna.ats.arjuna.recovery.TransactionStatusManager package) to check to

see if the original process is still alive, and if the transaction is still in progress. The RecoveryManager

only proceeds with recovery if the original process has gone, or, if still alive, the transaction is

completed. (If a server process or machine crashes, but the transaction-initiating process survives,

the transaction will complete, usually generating a warning. Recovery of such a transaction is the

RecoveryManager’s responsibility).
