Oracle 10gR2 installation on Z/Linux 5

I'm installing Oracle 10gR2 on Z/Linux 5.

While starting the installer, got the following errors:
JVMDG080: Cannot find class com/ibm/jvm/Trace
JVMXM012: Error occurred in final diagnostics initialization
Could not create the Java virtual machine.

Did export JAVA_COMPILER=NONE according to document 400785.1 then started it again. Now got a different error:

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2010-07-26_04-13-20PM. Please wait ...[oracle@zLinux70 database]$ The java class could not be loaded. java.lang.ExceptionInInitializerError

Then I tried the flag -ignoreSysPrereqs, and got the following errors:
Exception java.lang.ExceptionInInitializerError occurred..java.lang.ExceptionInInitializerError at java.awt.Component.(Component.java:548) at oracle.sysman.oii.oiif.oiifm.OiifmGraphicInterfaceManager.(OiifmGraphicInterfaceManager.java:222) at oracle.sysman.oii.oiic.OiicSessionInterfaceManager.createInterfaceManager(OiicSessionInterfaceManager.java:194) at oracle.sysman.oii.oiic.OiicSessionInterfaceManager.getInterfaceManager(OiicSessionInterfaceManager.java:203) at oracle.sysman.oii.oiic.OiicInstaller.getInterfaceManager(OiicInstaller.java:437) at oracle.sysman.oii.oiic.OiicInstaller.runInstaller(OiicInstaller.java:932) at oracle.sysman.oii.oiic.OiicInstaller.main(OiicInstaller.java:872)Caused by: java.lang.NullPointerException at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:2171) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:2006) at java.lang.Runtime.loadLibrary0(Runtime.java:824) at java.lang.System.loadLibrary(System.java:910) at sun.security.action.LoadLibraryAction.run(LoadLibraryAction.java:76) at java.security.AccessController.doPrivileged1(Native Method) at java.security.AccessController.doPrivileged(AccessController.java:287) at sun.awt.NativeLibLoader.loadLibraries(NativeLibLoader.java:81) at sun.awt.DebugHelper.(DebugHelper.java:56) ... 7 moreException in thread "main" java.lang.NoClassDefFoundError: oracle/sysman/oii/oiif/oiifm/OiifmMainFrame at oracle.sysman.oii.oiif.oiifm.OiifmGraphicInterfaceManager.(OiifmGraphicInterfaceManager.java:222) at oracle.sysman.oii.oiic.OiicSessionInterfaceManager.createInterfaceManager(OiicSessionInterfaceManager.java:194) at oracle.sysman.oii.oiic.OiicSessionInterfaceManager.getInterfaceManager(OiicSessionInterfaceManager.java:203) at oracle.sysman.oii.oiif.oiifm.OiifmAlert.(OiifmAlert.java:151) at oracle.sysman.oii.oiic.OiicInstaller.runInstaller(OiicInstaller.java:990) at oracle.sysman.oii.oiic.OiicInstaller.main(OiicInstaller.java:872)

It's working after run the verification utility supplied by Oracle. It's documented as
