Richard Achmatowicz commented on AS7-1751:
------------------------------------------
Discussed this issue with Paul and we decided to do the following:
(i) define a new attribute of the cache-container transport element called cluster which
allows specifying a name for the underlying JGroups channel used to support the cache
container:
{noformat}
<cache-container name="web" ...>
<transport cluster="some-cluster-name" .../>
</cache-container/>
{noformat}
(ii) allow the following attributes to allow expressions:
JGroups subsystem: default-stack, site, rack, machine
Infinispan subsystem: default-cache-container, default-cache, cluster
In this instance, we chose the minimal set of attributes which would be cluster / machine
dependent.
infinispan setup to support environment variables within the
standalone.xml file

Key: AS7-1751
URL:
https://issues.jboss.org/browse/AS7-1751
Project: Application Server 7
Issue Type: Enhancement
Components: Clustering
Affects Versions: 7.0.1.Final
Reporter: Dan Sirbu
Assignee: Richard Achmatowicz
Priority: Blocker
Fix For: 7.1.1.Final
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.
