Plsqloracle_home solution cannot be identified by plsql on 64-bit ORACLE clients
1. Problems

Plsql has only 32-bit programs so far, and most desktop systems use 64-bit windows operating systems. On 64-bit windows, in most cases, the 64-bit ORACLE client program is installed. This combination causes plsql to not identify the ORACLE_HOME directory and cannot read tnsnames. connection string in the ora File

2. Solution 2.1 configure ORACLE_HOME environment variables on windows

For example, the value of ORACLE_HOME in my environment is "C: \ oracle \ product \ 12.1.0 \ dbhome_1"

2.2 reference instantclient-basic-win32-10.2.0.5

Decompress the instantclient-basic-win32-10.2.0.5.zip file and copy the compressed file to the product directory in the installation directory of PLSQL Developer, for example, C: \ oracle \ product \. The final instantclient directory is C: \ oracle \ product \ C: \ oracle \ product \ instantclient-basic-win32-10.2.0.5 \ instantclient_10_2

Instantclient-basic-win32-10.2.0.5.zip files, the author has been uploaded to the "System Performance Optimization professional group" group sharing for you to download.

2.3 configure ORACLE_HOME and OCI database 2.3.1 in PLSQL to configure ORACLE_HOME

On the PLSQL Main Menu, Click Tools and select the Preferences sub-menu to go to the "preferred page" dialog box. On the right side of the "connection" tab, find "Oracle main directory name (empty for automatic detection )", enter the oracle home directory name in this box, for example, "C: \ oracle \ product \ 12.1.0 \ dbhome_1"

On the right side of the "connection" tab, find "OCI Library (empty for automatic detection )", enter oci in this box. dll file absolute path, such as: "C: \ oracle \ product \ instantclient-basic-win32-10.2.0.5 \ instantclient_10_2 \ oci. dll"

3. Results

After completing the preceding four steps, restart PLSQL to identify ORACLE_HOME and find the database connection string in the tnsnames. ora file of the ORACLE client.
