  ORA-28362: Master key not found tips

Oracle Database Tips by Donald BurlesonMarch 25, 2015

Question:  How to I stop the ORA-28362 error.  When when I delete my wallet and try to re-create it using: alter system set encryption key identified by "password"; it give "ORA-28362: master key not found" however it creates the wallet.

Answer:  First, try hard-coding the wallet location in the sqlnet.ora file.   The Oracle oerr utility says this about the ORA-28362 error:

ORA-28362: Master key not found

Cause:  The required master key required could not be located. This may be caused by the use of an invalid or incorrect wallet.

Action:  Check wallet location parameters to see if they specify the correct wallet. Also, verify that an SSO wallet is not being used when an encrypted wallet is intended.

see MOSC Note 1301365.1 titled "Known TDE Wallet Issues".  This could be Bug # 9215461 MOSC Doc 1301365.1 Notes:

"Modifying the wallet with OWM or orapki leads to various errors: ORA-600 [ZTSMSTORE FAILED], ORA-28368, ORA-28367, ORA-28362

It is sometimes needed to modify the TDE wallet manually, using OWM or orapki, in order to change the wallet password or to make it auto login. As a result, subsequent wallet access would fail with one of the errors ORA-600 [ZTSMSTORE FAILED], ORA-28368, ORA-28367, ORA-28362 The issue affects all Oracle releases using TDE."
