    After installing oracle 10gr2 on Leopard, got ORA-12547

      Hello everyone,

      I've installed on Leopard 10.5.6. Once I created a database, I connected to it and then logged out successfully. But after a reboot, I cannot connect to it anymore.

      SQL> conn / as sysdba
      ORA-12547: TNS:lost contact

      Here's lsnrctl output:

      And tnsping is OK:
