While configuring TDE and try to open with keystore command getting following error.

Error: ORA-28367: wallet does not exist

SQL> ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY password;
ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY password

ERROR at line 1:
ORA-28367: wallet does not exist

Solution:

Check the following view where the Oracle is finding the keys:

SQL> select wrl_parameter from v$encryption_wallet
;

WRL_PARAMETER
--------------------------------------------------------------------------------
E:\ORACLE\WALLETS\ORCL\tde\

Use this path while creating the encryption keys:

SQL> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE 'E:\ORACLE\wallets\orcl\tde' IDENTIFIED BY password;

keystore altered.

Open the keystore:

SQL> ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY password container=all;

keystore altered.
