    Oracle 11g R2 on CentOS 6.3, and Net Configuration Assistant

      This is my first time to install Oracle 11g R2 on Linux.

      I made all instructions in Oracle documentation.

      But in the installation process, the Net Configuration Manager is failed.

      I continued the process, and after it finished, I couldn't connect to the sqlplus.

      This is my tnsnames.ora

      # tnsnames.ora Network Configuration File: /Oracle/u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
      # Generated by Oracle configuration tools.

      ORCL =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
      (SERVICE_NAME = orcl.localhost)
      and listener.ora

      # listener.ora Network Configuration File: /Oracle/u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
      # Generated by Oracle configuration tools.

      LISTENER =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))

      ADR_BASE_LISTENER = /Oracle/u01/app/oracle
      Output of lsnrctl status

      Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521)))
      TNS-12541: TNS:no listener
      TNS-12560: TNS:protocol adapter error
      TNS-00511: No listener
      Linux Error: 111: Connection refused

      My Solutions:

      I open ./netca to reconfigure the listener again.

      But the program told me that the port is in use.

      I deleted it and added a new one but the same warning that port is in use
