Forum Reference:
Create a way to close XAResource at the end of the recovery cycle
processing
----------------------------------------------------------------------------
Key: JBTM-3325
URL:
https://issues.redhat.com/browse/JBTM-3325
Project: JBoss Transaction Manager
Issue Type: Enhancement
Components: JTA
Affects Versions: 5.10.5.Final
Reporter: Ondrej Chaloupka
Assignee: Ondrej Chaloupka
Priority: Major
From discussions about Narayana integration to Agroal (
https://agroal.github.io/) there
came an idea how to make easier for Agroal to integrate with Narayana recovery
processing.
Usually (or at least Agroal does so) the brand new {{XAResource}} is provided from the
call of the {{XAResourceRecovery}}
(
https://github.com/jbosstm/jboss-transaction-spi/blob/7.6.0.Final/src/mai...).
aka. Agroal implements the {{XAResourceRecovery}} and register it with the Narayana with
adding it to with
https://github.com/jbosstm/jboss-transaction-spi/blob/7.6.0.Final/src/mai...
to be used in {{XARecoveryModule}}.
When the periodic recovery cycle ends the {{XAResource}} is not used (next time the
recovery processing calls the {{XAResourceRecovery#getXAResources()}} to get the resource
for scanning again). The transaction manager announces that the scan ended with call
{{XAResource.recover(XAResource.TMENDRSCAN)}} (this is an internal to how Narayana
works).
It would be beneficial provide an option that Narayana closes {{XAResource}}s at the end
of the recovery cycle when Narayana does not plan to use it again.
The idea is to check if the {{XAResource}} is {{AutoCloseable}} and if so then the
{{XAResource}} is closed at the end of the recovery cycle processing.
