Hi, related to WFLY-3512, disable a datasource used by some application, undeploy the application, tested in 8.1 and 9.0 snapshot. I saw that org.jboss.as.connector.subsystems.datasources.DataSourceDisable (connector module) is called, but there is no previous check about deployments that uses it. How can datasource subsystem get to know the deployment dependencies for resources (datasource and resource adapter) ? Is there a listener mechanism where datasource subsystem can listen to deploy enablement, and check the resources dependencies ? This way, datasource subsystem can have a lista of dependency and check it before disable/remove of datasources. 1. https://issues.jboss.org/browse/WFLY-3512 -- Claudio Miranda claudio(a)claudius.com.br http://www.claudius.com.br
