Hi Gurus !!!

During upgrade from 9.2 to 10.2 we have install patches and now we are ready to call dbua (upgrade assistant).

When we call dbua an error occurs :


Error message

Failed to load Main Class: oracle.sysman.assistants.dbma.Dbma

We've check enviroments variables and all are Ok.

Any ideas ?

Thanks in advance.

thats a java error.

I´d guess there are some files missing within the oracle installation or he cannot find them or got the wrong permissions.

Could be .jar files.

Which user are you currently logged in and which OS type do you use?

On Linux you can try to "strace" the dbua to see where he gets a "file not found". So you know which file he´s complaining about.

Hi Xavier Canals Asin,

You also need to set the JAVA_HOME environment variable.

For unix after login to the oraSID user

setenv JAVA_HOME /opt/java1.4(java location may differ check in ur system)

then check the version of the java with command java -version

if still you are getting the error

check the metalink

Exception in thread "main" java.lang.NoClassDefFoundError [ID 359067.1]

If still it is not working please reply back to me.
