Net8 Getting Started Release 8.0.6 for Windows NT and Windows 95/98 A70007-01 |
|
This appendix describes how to edit and add Oracle-related settings.
Specific topics discussed are:
Net8 contains the following registry entries:
Description | Default Value Entry |
---|---|
Specifies the location of the Net8 directory. |
ORACLE_HOME\NET80 |
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES contains subkeys that correspond to services. Depending upon what is installed, possible Net8 services are:
Each service subkey contains the following parameters:
To edit the Oracle-related settings:
On Windows NT: |
C:\>REGEDT32
|
On Windows 95/98: |
C:\>REGEDIT
|
The Registry Editor window appears:
The left-hand side of the windows shows the hierarchy of registry keys, and the right-hand side of the window shows various values associated with a key:
An editor dialog box appears:
You can use the following parameters on Windows NT and Windows 95/98:
Net8 first checks for the parameters as environment variables, and uses the values defined. If environment variables are not defined, these parameters are searched for in the registry.
You can add the LOCAL parameter to make a connection without specifying a connect string service name. The value for LOCAL is the service name in the TNSNAMES.ORA file located in the ORACLE_HOME\NET80\ADMIN directory.
For example, if the LOCAL parameter is specified as finance, you connect to a database from Server Manager with the following:
SVRMGR> CONNECT SCOTT/TIGER
Net8 checks if LOCAL is defined as an environment variable or as a parameter the registry, and uses finance as the service name. If it exists, Net8 connects.
You can add the TNS_ADMIN parameter to change the directory name for configuration files from the default location. For example, if you set TNS_ADMIN to ORACLE_HOME\TEST\ADMIN, the configuration files are used from ORACLE_HOME\TEST\ADMIN.
You can set the USE_SHARED_SOCKET parameter to TRUE to enable the use of shared sockets. It this parameter is set to TRUE, the network listener passes the socket descriptor for a client connections to the database thread. The result is the client does not need to establish a new connection to the database thread, and database connection time improves. Also, all database connections share the port number used by the network listener, and this may be useful if you are setting up third-party proxy servers.
Enabling this option, however, does not allows you to bring the network listener up and down if any database connection spawned by the network listener is active. You may need to shut down all the databases serviced by a network listener before you can bring down and restart a network listener. This is because shared sockets implementation in WINSOCK2 does not allow a thread to a network listener on a port number reliably if some other connections are active on the port.
This parameter only works in a dedicated server mode in a TCP/IP environment.
You can add these optional configuration parameters in three ways:
C:\>SET LOCAL=SERVICE_NAME
This method only lasts for the current login session.
The parameters must have a value class of REG_EXPAND_SZ and be located:
The instructions below explain how to add a parameter entry to the registry.
To add a parameter to the registry:
On Windows NT: |
C:\>REGEDT32
|
On Windows 95/98: |
C:\>REGEDIT
|
The Registry Editor window appears.
The Add Value dialog box appears:
The String Editor dialog box appropriate for the data type appears:
The Registry Editor adds the parameter.
The registry exits.
The instructions below explain how to add a parameter entry to the Control Panel System Properties window. This functionality is only available on Windows NT.
To add a parameter:
The System Properties window appears.
The Environment view appears:
The parameter is added to the System Variables list box.
