[jboss-jira] [JBoss JIRA] (WFCORE-1255) ugly style allowing to start multiple servers refer to the same server-config file

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-1255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13143843#comment-13143843 ] 

Brian Stansberry commented on WFCORE-1255:
------------------------------------------

JEPS 102 (http://openjdk.java.net/jeps/102) may make it feasible to do something meaningful about this (i.e. drop a PID in a file in the data dir and fail boot if there's already such a file and the process with that pid is still alive.)

> (1) create datasource "ds4node1" to node1 which created above.

> (2) careate datasource "ds4node2" to node2
>     and ds4node1 which was created in step(1) is deleted from standalone.xml,
>     ds4node2 is written into  standalone.xml.    
> ↓
> (3) careate datasource "ds4node3" to node3
>     and ds4node2 which was created in step(2) is deleted from standalone.xml,
>     ds4node3 is written into  standalone.xml.

> after restarting the three nodes, the three nodes refers to standalone.xml, and share the last created datasource "ds4node3"。
