Generally, in Visual Studio subscriptions, this requirement applies to Windows, Windows Server, Microsoft Office client applications, and Expression Studio. Activating a productĪctivation is required for certain products. If you need downloads and/or product keys, contact your admin. If access to downloads is disabled for your subscription, access to product keys is also disabled. ODBC users should follow the ODBC Installation Instructions.If your subscription is provided to you by your work or school, your subscription admin controls whether you get access to software downloads. Then set the environment variable TNS_ADMIN to that directory name. This is the default Oracle client configuration directory for applications linked with this Instant Client.Īlternatively, Oracle client configuration files can be put in another, accessible directory. If you intend to co-locate optional Oracle configuration files such as tnsnames.ora, sqlnet.ora, ldap.ora, or oraaccess.xml with Instant Client, then create a subdirectory such as C:\oracle\instantclient_19_3\network\admin.Instant Client 12.1 requires the Visual Studio 2010 redistributable. Instant Client 18 and 12.2 require the Visual Studio 2013 redistributable. Instant Client 19 requires the Visual Studio 2017 redistributable.


Restart any terminal windows or otherwise make sure the new PATH is used by your applications. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path. Add this directory to the PATH environment variable.Unzip the packages into a single directory such as C:\oracle\instantclient_19_3.All installations require the Basic or Basic Light package.

Download the appropriate Instant Client packages for your platform.For example, Oracle Call Interface 19, 18 and 12.2 can connect to Oracle Database 11.2 or later. See the Instant Client Home Page for more information about Instant Client packages.Ĭlient-server version interoperability is detailed in Doc ID 207303.1.
