ERROR => JHVM_LoadJavaVM: Cannot create Java VM (rc=-6)

[Former Member]

Hi experts

We installed JAVA AS, EP Core and EP (netweaver2004s) on windows 2003 SP2 x64 and MS SQL 2005 as MSCS.

We installed system succesfully. After changing some java parameter for both dispatcher and server via configtool. We could not start system.

We see this messages

dev_server0:

Hi

I know that oss note. Our problem occured after applying of that oss note.

There are two instance on our system because of MSCS. We applied all parameters on both instance. We could not remember default values of parametres, so we could not undo.

How can we find which parameter cause this problem?

Hai,

have a look at the following parameters for JVM in config tool.

<b>Memory Works in JAVA (JVM):</b>

Two types of memory: 1.Heap, 2.Perm

--> When Objects are instantiated, they use heap memory.

--> when a new class is loaded, it uses perm memory.

Each memory type has a start and max setting. Make the start and max settings for

heap the same.

--> -Xms1024m start

--> -Xmx1024m max

You may increase the value if you have sufficient memory available.

Make the start and max settings for Perm for the same fixed value

--> -XX:PermSize=128m start

--> -XX:MaxPermSize=128m max

hope this helps..

Regards,

Gopinathan.

Hi Gopinathan

There are six location for these parameters.

cluster_data ->instance_ID18808->servers general

cluster_data ->instance_ID18808->dispatcher_ID1880800->general

cluster_data ->instance_ID18808->server_ID1880850->general

cluster_data ->instance_ID76308->servers general

cluster_data ->instance_ID76308->dispatcher_ID7630800->general

cluster_data ->instance_ID76308->server_ID7630850->general

Which of these i should change?

Best Regards....

Hai,

These above settings can apply to the Servers (not dispatcher). So edit in the server Settings.
