Oracle Database Discussions

Hi,

i've been getting PROTOCOL VIOLATION ERROR when java based applications trying to connect to Oracle 10g. The jdbc drivers tried are classes1.zip, classes12.jar, ojdbc4.jar, ojdbc5.jar. But of no use. This error associates the following errors also

java.sql.SQLException: OALL8 is in an inconsistent state.
ora-12155: TNS: received bad datatype in NSWMARKER packet.

Tried to connect thru TOAD also but of no use.

Is this a problem with oracle or ???.

I've tried of tracing the tns connections i cudn't find any errors.
