TNS-00583: Valid node checking: unable to parse configuration parameters

 TNS-12560: TNS:protocol adapter error  TNS-00583: Valid node checking: unable to parse configuration parameters

I  Received following errors when trying to startup my listener. I verified the listener.ora and sqlnet.ora files and everything seemed to look normal.

I had below line in my sqlnet.ora file.

[oracle@Linux03 admin]$ cat sqlnet.ora_bak
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/12.1.0.2/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ENCRYPTION_WALLET_LOCATION =
  (SOURCE =(METHOD = FILE)(METHOD_DATA =
    (DIRECTORY = /u01/app/oracle/admin/$ORACLE_SID/encryption_keystore/)
   

Solution (in my case): Removing the ENCRYPTION_WALLET_LOCATION info did the trick for me.

[oracle@Linux03 encryption_keystore]$ lsnrctl start
