5,配置tnsnames.ora后出现的错误

配置监听再次打开实例的时候出现下列问题：

ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Solaris-AMD64 Error: 2: No such file or directory
Process ID: 0
Session ID: 0 Serial number: 0

经过了解是因为在配置tnsnames.ora的时候将ip改成了服务器主机号，改回服务器ip后oracle正常启动

希望知道的大神帮忙告知一下

LISTENER_TESTDB11 =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.103)(PORT = 1521))

TESTDB11 =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.103 )(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TestDB11)
    )
)

ORA-01034 ORA-27101
