The *.ora file location can be a location different from the standard ORACLE_HOME /network/admin directory. NET configuration file or within the *.ora file itself. ODP.NET tnsnames.ora, sqlnet.ora, and ldap.ora parameter values can be set in a.

Even if the user does not have all the database connection information readily available, Oracle recommends inserting placeholder values during the install process, then modifying the tnsnames.ora file later with actual values to replace the placeholders. If no alias information is provided, then no tnsnames.ora file is created. OUI then automatically creates the tnsnames.ora file.
If you install onto a computer without any previous Oracle homes present, then OUI prompts the user for the database connection alias information. If you install into an existing ODAC or RDBMS Oracle home, then no new *.ora files is copied or created. The *.ora files can be customized if the new Oracle home uses a different configuration from the previous Oracle home from which the files were copied over. OUI provides location information for these files from up to three other existing Oracle homes if they exist. That is, they are both 32-bit installations or they are both 64-bit installations.Īlternatively, existing *.ora files can be copied over from another existing Oracle home, besides the last active one, to the new ODAC Oracle home.
When installing Oracle Data Access Components (ODAC) in a new Oracle Home, Oracle Universal Installer (OUI) automatically copies the Oracle local naming (tnsnames.ora), profile (sqlnet.ora), and directory (ldap.ora) parameter files and settings from an existing Oracle home into the newly installed ODAC home, as long as they share the same bitness. 1 is equivalent to true and 0 is equivalent to false. NET configuration settings accept true, false, 1, and 0 as valid values.

ODP.NET only reads the Windows Registry and the XML configuration file when it is loaded into memory, thus any configuration changes made after that are not read or used until the application is re-started.Īll boolean attributes in ODP.NET. NET Framework on which ODP.NET runs, not from the version of ODP.NET. Note that ODP.NET reads the nfig files from the version of the. Note that for any setting that does not exist in a config file ( nfig or application/web config), the value in the registry for a loaded version of ODP.NET is used, as in previous releases. However, having ODP.NET configuration values in the application or web config file assure that these settings are applied only for that application, thus providing more granularities.įor example, if the application or web.config file has a StatementCacheSize configuration setting of 100, this application-specific setting forces the version of ODP.NET that is loaded by that application to use 100 for the StatementCacheSize and overrides any setting in the nfig and in the registry. The Windows registry value settings for a given version of ODP.NET affect all the applications that use that version of ODP.NET. The application or web config file can be useful and sometimes essential in scenarios where more than one application on a computer use the same version of ODP.NET, but each application needs a different ODP.NET configuration. Īny attribute settings that are equivalent to the connection string override everything. To override the nfig subsection, create a subsection for that version in the app/web/config file, that is.
For and sections, a nfig with a specific ODP.NET version subsection, that is,, will override an app/web.config subsection that references all versions generically, that is. There is one exception to app/web/config settings overriding nfig.
