[jboss-jira] [JBoss JIRA] Commented: (AS7-1751) infinispan setup to support environment variables within the standalone.xml file

    [ https://issues.jboss.org/browse/AS7-1751?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12627740#comment-12627740 ] 

Brian Stansberry commented on AS7-1751:
---------------------------------------

My comment above wasn't meant to discourage doing this or to argue for or against doing it by default. Paul, I'm just pointing out the proper way to implement this. The core management layer has a standard way of dealing with expressions (i.e. system property substitution) in configuration values, and that should be used. But it's not used a lot, so people may not know about it and instead roll their own solution.

> When I kickstart the inifispan subsystem by using the start=EAGER option, saw that there are multiple "clusters" that get kickstarted as: 
>     GMS: address=traffic_instance_PL-3-31315, cluster=hibernate
>     ........................................, cluster=web
> and others.
> Now, if I do have mutliple blades e.g. SC-1, SC-2, PL-3, PL-4 and then I would like to define two clusters e.g. "oam" , "traffic" where "oam" should be assigned for SC-x and "traffic" for PL-x, then I will certainly need to go in the standalone-ha.xml file and change all the "cache-container name" entries in order to have "oam" cluster distinguished from "traffic" cluster, right ?
> If so, it would be better if for example I could pass an jvm option via e.g. -DCLUSTER="oam" and then in the standalone-ha.xml file have this set as: "cache-container name=${CLUSTER}-"
> In this way, I can obtain a dynamic config at runtime.
