How do I configure remote access in Oracle? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1. Network snooping configuration

# listener.ora Network Configuration File: C:\ app\ Administrator\ product\ 11.2.0\ dbhome_1\ network\ admin\ listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER = SID_LIST = (SID_DESC = (SID_NAME = CLRExtProc) (ORACLE_HOME = C:\ app\ Administrator\ product\ 11.2.0\ dbhome_1) (PROGRAM = extproc) (ENVS = "EXTPROC_DLLS=ONLY:C:\ app\ Administrator\ product\ 11.2.0\ Dbhome_1\ bin\ oraclr11.dll ") LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1521)) (ADDRESS = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521)) ADR_BASE_LISTENER = C:\ app\ Administrator

For more than one IP, it is as follows:

LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1521)) (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 172.24.226.2) (PORT = 1521))) (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 172.24.226.3) (PORT = 1521)))

2.TNS configuration

# tnsnames.ora Network Configuration File: C:\ app\ Administrator\ product\ 11.2.0\ dbhome_1\ network\ admin\ tnsnames.ora# Generated by Oracle configuration tools.ORCL= (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl)) ORACLR_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (PROTOCOL = IPC) (KEY = EXTPROC1521))) (CONNECT_DATA = (SID = CLRExtProc) (PRESENTATION = RO)) LISTENER_ORCL = (ADDRESS = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521))

For more than one IP, it is as follows:

ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = 172.24.226.2) (PORT = 1521)) (ADDRESS = (PROTOCOL = TCP) (HOST = 172.24.226.3) (PORT = 1521)) (SOURCE_ROUTE = yes) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl))

3. Stop and start the service

Stop the following services before starting.

OracleOraDb11g_homeTNSListenerOracleService*

Client configuration

1. Download the ODAC package.

two。 Extract the downloaded ODAC package.

3. Execute installation command

Example:

Install.bat all D:\ Program\ ODAC\ 12040x64 OracleHome true

4. Add environment variabl

ORACLE_HOME: is the directory where ODAC is installed.

TNS_ADMIN: the directory where the file tnsnames.ora is located, usually in network\ admin under the ODAC installation directory.

Note: TNS_ADMIN can be directly copied to the ODAC installation directory without adding the tnsnames.ora file.

Add% ORACLE_HOME% to the PATH environment variable.

5. Configure TNS

Add to the configuration file tnsnames.ora

DBORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST =) (PORT = 1521)) CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME =)

Description:

The IP or computer name of the database computer

: name of the database TNS configuration
