Multi node EBS 11.5.10

I have deleted my single instance EBS 11.5.10 environmenr and installed a multi node 11.5.10 environment. I have two nodes, and seperated the database + conc. managers from the application tier. Everything seems to work fine, but when I want to startup a forms session..something goes wrong with the jinitiator. Maybe someone has had the same problem.
In the javaconsole I recieve the following error :

Support status Oracle on vmware...

Following support status from Metalink note 249212.1

Oracle provides support of the Oracle Stack when running on a VMware virtual machine in the following manner. If a problem arises and it is a known Oracle issue, Oracle support will recommend the appropriate solution. If that solution does not work, the issue will be referred back to VMware for support. If the problem is determined to be an unknown Oracle issue when running on a VMware virtual machine, and the issue cannot be reproduced on a physical system by Oracle support, the issue will be referred back to VMware for support. Oracle and VMware have in place a joint customer support agreement to enable customer support issues to be transferred between the two partners. In addition, all versions of RAC are not supported on VMWare by Oracle.

changing applications background

Some practical notes times time. For my own EBS 11.5.10 installation I wanted to change the background in applications. To do this, modify the $OA_HTML/bin/appsweb.cfg
Look for 'background' and give the complete path to the gif you want to use. The gif must be placed in the $JAVA_TOP/oracle/apps/media directory.

When you bounce the webserver, youw own background should be visible.

You can also change or remove the default Oracle splash screen. In the same appsweb.cfg, look for splashscreen and comment it out or change the gif, be sure to place the new gif in the same directory.
