The Oracle Client is a software suite allowing you to administer your database remotely, perform basic network configurations, write PL/SQL applications, connect your database to Java, Python type applications, etc. To be able to do that, you may install the Oracle Database Client and configure it correctly.


If you install the Toad with ignoring the warning message, you will get Ora-655535 error message when you open Schema Manager of Toad.To administer your Oracle Database remotely, you will need to connect to the database instance, especially from an SQL*Plus terminal. Without this variable, you will see 'oracle 64 bit client failed with warning' message. Or add C:\Oracle\19.3\InstantClient_圆4 to PATH environment variable in the first place. Install Toad for Oracle 13.1.1.5 64 bitsĬreate OCI_LIB64 environment variable to C:\Oracle\19.3\InstantClient_圆4 An x86 application will load the x86 libraries, and an 圆4 application loads the 圆4 libraries without any further modification on your system. Set TNS_ADMIN environment variable to a common location, for example TNS_ADMIN=C:\Oracle\Common\network\adminġ0. HKLM\Software\Wow6432Node\ORACLE\KEY_OraClient193_home1\ORACLE_HOME_NAME to OraClient193_home1ĩ. Using C:\Oracle\19.3\InstantClient_x86 should also work. Set Registry value - HKLM\Software\Wow6432Node\ORACLE\KEY_OraClient193_home1\ORACLE_HOME to C:\Windows\System32\ora193 ( not C:\Windows\SysWOW64\ora193 ). Using C:\Oracle\19.3\InstantClient_圆4 should also work.Ĩ. HKLM\Software\ORACLE\KEY_OraClient193_home1\ORACLE_HOME_NAME to OraClient193_home1 Open Registry Editor and set Registry value - HKLM\Software\ORACLE\KEY_OraClient193_home1\ORACLE_HOME to C:\Windows\System32\ora193 If needed set your ORACLE_HOME environment variable to C:\Windows\System32\Ora193ħ. NOTE : C:\Windows\SysWOW64\ora193 must not be in PATH environment variable.Ħ. Modify the PATH environment variable, replace all entries like C:\Oracle\19.3\InstantClient_x86 and C:\Oracle\19.3\InstantClient_圆4 by C:\Windows\System32\ora193, respective their \bin subfolder. Run command line tool, go to folder %WINDIR%\SysWOW64 and create a symbolic link ora193 to folder C:\Oracle\19.3\InstantClient_x86 Run command line tool, go to folder %WINDIR%\System32 and create a symbolic link ora193 to folder C:\Oracle\19.3\InstantClient_圆4 Download and unzip Oracle 圆4 client to C:\Oracle\19.3\InstantClient_圆4ģ.

Download and unzip Oracle x86 client to C:\Oracle\19.3\InstantClient_x86Ģ. ORACLE_HOME_NAME is called OraClient193_home1ġ. Below procedures show how to install 32-bit and 64-bit Oracle Clients on 64-bit Windows machine.
