One EUS wallet per database

Hello,

I'm working with 11.2 and 12.1 databases versions; I use EUS and TDE components and my question is about the management of EUS wallet(s).

With TDE, it's possible to define one encryption wallet per database by including the $ORACLE_SID in the encryption wallet location like that:

ENCRYPTION_WALLET_LOCATION=

  (SOURCE=

    (METHOD=FILE)

      (METHOD_DATA=

        (DIRECTORY=/var/opt/oracle/Wallets_TDE/$ORACLE_SID/)))

For EUS, is it also possible to include the $ORACLE_SID in the wallet location in order to specify one EUS wallet per database like that:

WALLET_LOCATION =

  (SOURCE =

    (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /var/opt/oracle/Wallet_EUS/$ORACLE_SID/)
