OWM says "The directory OH /owm/wallets/oracle" does not exist

Question

Hello, RHEL 6, x86-64
Oracle 11.2.0.4 Ent Edition
I just upgraded the database from 11.2.0.3 to 11.2.0.4.  User reports "ORA-28365: wallet is not open" while trying to access tables in a certain schema.
I have little experience with Wallet so I find out that I can "open" the wallet using OWM.  I start OWM and follow the instructions in section 9.4.3 of http://docs.oracle.com/cd/B28359_01/network.111/b28530/asowalet.htm#i1006711, and after step 2 which is to select a directory for the wallet, it tells me, ""The directory <OH>/owm/wallets/oracle" does not exist".  Ahh!  (By the way, this was when I was pointed to the ORIGINAL oracle home (11.2.0.3) because I wanted to see if the wallet existed there.
Now I am moderately panicked.  What do I try next?  I gotta get the wallet open!
Thank you in advance for taking the time.
Humbly,

Hi,
If you have TDE encrypted objects, one must open the wallet from the sqlplus.
1) make sure the sqlnet.ora from your $ORACLE_HOME/network/admin has ENCRYPTION_WALLET_LOCATION parameter set, example:
ENCRYPTION_WALLET_LOCATION =
(SOURCE =
  (METHOD = FILE)
  (METHOD_DATA =
  (DIRECTORY = /home/oracle/wallet)
2) connect as sysdba and run:
   alter system set encryption wallet open identified by "wallet_password";
3) select wallet status and path from : select * from v$encryption_wallet;
4) select again from the encrypted objects
