I exported a database to a transportable tablespace and send the data to a customer. They received the error: ORA-28365 Wallet is not open. Do I need to close the wallet before creating the export? Is there something on the customer's end that they can do to allow them to import this data?
Haven't had this problem with any other customer since switching to 12c in the last 6 months so this is strange to me that this is the only customer having this problem?
Thanks for any insight!
