Hi All,

Can someone please help in analysis of the GC logs of WAS 7 (64 Bit) on Solaris (System Configuration: Sun Microsystems sun4v SPARC Enterprise T5120 & Memory size: 65408 Megabytes).

The application seems to be having a unusual large GC.

Can someone provide any hits at where i can start looking at tuning the GC.

The application is a JSF (WAS 7 - JSF 1.2) application. The application was working really well in WAS 6.1 (JSF 1.1)

mx - Min Heap Size 2300
ms - Max Heap Size 2300
PermSize 512
MaxPermSize 512
MaxNewSize - -XX:MaxNewSize 1000
NewSize --XX:NewSize 1000
-XX:SurvivorRatio=6
-XX:+UseConcMarkSweepGC
-XX:+UseParNewGC
-XX:ParallelGCThreads=16


We have observed the following in the GC. can this impact the performance ? what are the time specified in like user , sys and real ?

CMS: abort preclean due to time 77664.614: CMS-concurrent-abortable-preclean: 8.588/8.588 secs Times: user=8.65 sys=0.15, real=8.59 secs

NamingException on call from WPS 6.1 Portlet to Remote EJB 3.0 on separate Machine

Hi All

Just attaching a small diagrammatic representation of my problem.


Hi all

i am trying to call a EJB3.0 in WAS 6.1.0.13 server from a WPS Express (WPS 6.1.0.15) that is in a separate instance.

i have got the signer certificate for a SSL Connection.

when i try to call the EJB i am able to get the Context

System.out.println(ctx.getEnvironment());

but when it comes to lookup it give the following exception

Object obj = ctx.lookup("ejb/JPAEJBEAR/JPAEJB.jar/CreditorBean#com.dk.bs.ejb.CreditorI nterface");

System.out.println(obj.toString());

CreditorInterface credInterface = (CreditorInterface)PortableRemoteObject.narrow(obj, com.dk.bs.ejb.CreditorInterface.class);



Creditor objCreditor = new Creditor(new Integer(302), new Double(1.0D), new String("work"), new Date(), new Date(), new Date(), "test", new Date());

System.out.println(credInterface.toString());

credInterface.addCreditor(objCreditor);

System.out.println("Creditor Done");
