Unable to export
Without writing it long, here is the story. Our daily backup is simple and strange forward. The Oracle database is on a Windows Server.
A scheduled task is run every night. This scheduled task basically just triggers to run a cmd file.
In the cmd file, it has the conventional export command, exp xxx/xxx@xxx
No problem, every day is happy and running. Last Monday, per our vendor's request, we need to install a second
Oracle Client 11g on it to run a new version of vendor base application, existing one in the server installed is 10g client by the way.
