We have an Oracle database server (maintained and supported by 3rd party co). It developed an issue some time ago (its a standby server) whereby the connection cannot be made from the 3rd party program to the database via odbc.
They had a brief look at it and quoted to fix the issue 'due to a hardware problem' of some kind. The server/database is running on a VM so we have argued that the problem isn't hardware, rather oracle/software.
They also said it has an 'internal oracle error 600' which relates to hardware problem. I've searched and cannot see anything that would indicate this problem.
We are now nowhere further to resolving.
Is there anyone that has come across this sort of problem and pointers for me proving this is really not a hardware fault?
