[esb-issues] [JBoss JIRA] Commented: (JBESB-3286) Having the value "create" for the Juddi persistence.xml "hibernate.hbm2ddl.auto" property breaks the juddi Dabase in a ESB cluster

    [ https://jira.jboss.org/jira/browse/JBESB-3286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12526126#action_12526126 ] 

Kevin Conner commented on JBESB-3286:
-------------------------------------

We had "update" in there initially, but were advised not to use it and that we should change it to "create" instead.

The downside of this is that it does delete the database on startup, which is problematic in a cluster.

We definitely need to handle this better.

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: Registry and Repository
>    Affects Versions: 4.8
>         Environment: JBoss ESB 4.7 CP1 or 4.8 cluster with at least two JBoss ESB instances sharing the same Juddi database
>            Reporter: Maurice Zeijen

> In a ESB cluster, with a shared Juddi DB, the value "create" for the Juddi persistence.xml "hibernate.hbm2ddl.auto" property causes the juddi database to be recreated after every JBoss ESB Instance is started. This results in the removal of the service registration of the JBoss ESB that was started first.
> The following happens:
>  - JBoss ESB server 1 starts
>  - Tables in the Juddi database get created
>  - Registry entries of JBoss ESB server 1 are created in the Juddi database
>  - JBoss ESB server 2 starts
>  - All records in the existing tables of the Juddi database are deleted.
>  - Registry entries of JBoss ESB server 2 are created in the Juddi database
