Hang/slowness in WebSphere Application Server Administrative console
 Technote (troubleshooting)
 
Problem(Abstract)
Hang/slowness in IBM WebSphere Application Server Administrative console to check the status of application servers or applications.
 
Cause
When the server status page is accessed, deployment manager will communicate with all node agents to get the server status. This could take long time. The status of the servers are not cached. So, if there are lot of servers, you will notice significant amount of delay in loading status of all servers.

If you take javacores, the stack for the thread will be similar to one shown below:

at java.net.Inet4AddressImpl.getLocalHostName(Native Method)
at java.net.InetAddress.getLocalHost(InetAddress.java(Compiled Code))
at org.apache.soap.util.mime.MimeUtils.getUniqueValue(Unknown Source)
at org.apache.soap.rpc.SOAPContext.setRootPart(Unknown Source)
at org.apache.soap.rpc.SOAPContext.setRootPart(Unkkkkkknown Source)
at org.apache.soap.rpc.SOAPContext.setRootPart(Unknown Source)
at org.apache.soap.transport.TransportMessage.save(Unknown Source) at com.ibm.ws.management.connector.soap.SOAPResponse.writeSOAPResponse( SOAPResponse.java(Compiled Code))
at com.ibm.ws.management.connector.soap.SOAPConnector.service(SOAPConnector.java Compiled Code))
at com.ibm.ws.management.connector.soap.SOAPConnection.handleRequest (SOAPConnection.java(Compiled CODE))
at com.ibm.ws.http.HttpConnection.readAndHandleRequest(HttpConnection.java(Compiled Code))
at com.ibm.ws.http.HttpConnection.run(HttpConnection.java(Compiled code)
........

 
Resolving the problem
Add the below property in generic command line arguments for Deployment Manager JVM to cache the localhost information:
-Dcom.ibm.cacheLocalHost=true

Instructions to set the above property from console

  1. Open administrative console,
  2. Expand System Administration
  3. Select Deployment Manager > JVM Settings > System Property > New
  4. Add a new Custom Property for JVM to cache the local host information:
    System Property Name: com.ibm.cacheLocalHost
    System Property Value: true
  5. Save changes and restart the Deployment Manager.
