Hi,

We are continuously getting core dump files generated, when we issue sqlplus command from the HP-UX Virtual machine running 11.31 and also bus error messages. Pls see the below message from server.

$ sqlplus "/ as sysdba"
Illegal instruction(coredump)

$ rm -f corea

$ sqlplus "/ as sysdba"

Have you analyzed it with gdb? Can you get a stack trace?
gdb sqlplus core
Did it say you have a NaT fault?

Hi,

Thanks for the reply... This is a virtual machine which we have installed using a net_recovery created from another virtual machine.

The following errors are seen in the alert log, and these errors disappeared when the server was rebooted.

But now we often see â Illegal instruction (core dump)â error and the sessions terminated and when we try the next time it works.

ORA-07445 is very generic error and is OS dependent.
I would suggest you log a SR with Oracle with the information you provided.
This could be a bug.
