1、监听程序配置：

[oracle@localhost admin]$ vim listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

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

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = sun)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

(global_dbname = sun)

)

(SID_DESC =

(SID_NAME = sun1)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

(global_dbname = sun1)

)

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

(PROGRAM = extproc)

)

)

2、配置tnsnames.ora:

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

SUN =

(DESCRIPTION =

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

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = sun)

)

)

SUN1 =

(DESCRIPTION =

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

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = sun1)

)

)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

)
