[infinispan-issues] [JBoss JIRA] Commented: (ISPN-267) Change Infinispan cache manager jmx name to be hostname:<jmx-port> based

[Galder Zamarreno (JIRA)]

    [ https://jira.jboss.org/jira/browse/ISPN-267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12494301#action_12494301 ] 

Galder Zamarreno commented on ISPN-267:
---------------------------------------

Using InetAddress.getLocalHost().getHostName should be fine because the jmx code in the vm always tries to bind to InetAddress.anyLocalAddress(), which is 0.0.0.0. So, there's no way you can start two jmx agents in the same port in a machine, hence, for only naming purposes, we can safely assume that there won't be 2 identical combos of InetAddress.getLocalHost().getHostName():<jmx:port>

> <galderz> until now, i had named the CacheManager in jopr as: global-jmx-domain at address
> <galderz> this is a bit of pain because the address changes everytime you restart infinispan
> <galderz> but jopr does not realise this and considers an infinispan started in same jmx port in same address to be the same
> <galderz> so, when you restart, u see infinispan cache manager in jopr but it has the wrong name, this will be confusing
> <galderz> heiko told me this is a limitation of the jopr
> <galderz> on top of that, if u wanna do things correctly and import the new cache manager, u need to delete the old one, let auto discovery run and get the new one
> <galderz> and then you're back to your starting point, so if had tweaked any scheduling options in the previous infinispan instance, you're back to defaults
> <galderz> so, i'm gonna change this name to simply be:  global-jmx-domain at InetAddress.getLocalHost().getHostName():<jmx:port>
> <galderz> that way we'll avoid this confusion and you can always get the address from the RpcManager, so not big deal
