Remove all calls to InetAddress.getHostName() (causes reverse DNS lookup)
-------------------------------------------------------------------------
Key: JBAS-3794
URL: http://jira.jboss.com/jira/browse/JBAS-3794
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Clustering
Affects Versions: JBossAS-4.0.4.GA
Environment: Java 5
JBoss 4.0.4
Reporter: Michael Newcomb
Assigned To: Brian Stansberry
Priority: Minor
Any call to InetAddress.getHostName() will cause a reverse DNS lookup. If DNS is not configured properly, can cause slow startup/join times between JBoss clusters.
The most notable is in ClusterNode.java:
public ClusterNode(IpAddress jgAddress)
{
if (jgAddress.getAdditionalData() == null)
{
this.id = jgAddress.getIpAddress().getHostAddress() + ":" + jgAddress.getPort();
}
else
{
this.id = new String(jgAddress.getAdditionalData());
}
this.originalJGAddress = jgAddress;
StringBuffer sb = new StringBuffer();
java.net.InetAddress jgIPAddr = jgAddress.getIpAddress();
if (jgIPAddr == null)
sb.append("<null>");
else
{
if (jgIPAddr.isMulticastAddress())
sb.append(jgIPAddr.getHostAddress());
else
----->>>> sb.append(getShortName(jgIPAddr.getHostName()));
}
sb.append(":" + jgAddress.getPort());
this.jgId = sb.toString();
}
The following:
if (jgIPAddr.isMulticastAddress())
sb.append(jgIPAddr.getHostAddress());
else
sb.append(getShortName(jgIPAddr.getHostName()));
should be replaced with:
sb.append(jgIPAddr.getHostAddress());

[JBoss JIRA] Created: (JBCLUSTER-135) Extract the common use clustering code from the JBoss AS codebase
by Brian Stansberry (JIRA)
Extract the common use clustering code from the JBoss AS codebase
-----------------------------------------------------------------
Key: JBCLUSTER-135
URL: http://jira.jboss.com/jira/browse/JBCLUSTER-135
Project: JBoss Clustering
Issue Type: Task
Security Level: Public (Everyone can see)
Reporter: Brian Stansberry
Assigned To: Brian Stansberry
Priority: Critical
Fix For: Q3Y6
Remoting, Messaging, JBoss Cache and JBoss AS all have clustering aspects to their functionality. There is potential for code reuse between these projects that can't be realized if the clustering code resides in the cluster module of the AS codebase.
1) Extract general purpose clustering code from the AS cluster module into a separate project and produce binaries that other projects can use without creating a dependence on the AS project.
2) Provide APIs that both support standalone functionality of non-AS projects and facilitate ease of integration into the AS.
This task is meant to be an umbrella task, with specific detailed subtasks.
This task is primarily focused on meeting the short requirements of JBMESSAGING-516, but we also need to give due consideration to potential use in other projects.
