Win8 64-bit +oracle 11g 64-bit use PL/SQL Developer workaround

1) Install Oracle 11g 64-bit
2) Installing the 32-bit Oracle Client (instantclient-basic-win32-11.2.0.1.0)
Download Instantclient-basic-win32-11.2.0.1.0.zip (must be 32-bit, do not make the wrong version, the Oracle website has downloaded), Unzip it to product under the Oracle installation directory (this machine is named: instantclient_11_2): D:\Oracle\app\YM\product\instantclient_11_2.
Copy a directory under the root directory of the database installation D:\Oracle\app\YM\product\11.2.0\dbhome_1\NETWORK to the Oracle client directory D:\Oracle\app\YM\product\ Instantclient_11_2 (in fact, only need to Network\admin\tnsnames.ora, it is best to copy this file directly into the D:\Oracle\app\YM\product\instantclient_11_2 directory)
3) Install PL/SQL Developer
Install PL/SQL Developer, set up OCI library and Oracle_home in Perference->connection, for example, native settings:
Oracle home:d:\oracle\app\ym\product\instantclient_11_2
OCI Library:d:\oracle\app\ym\product\instantclient_11_2\oci.dll

4) Set Environment variables (modify path and tns_admin environment variables)


For Nls_lang environment variables, it is best to set to the same as the database side, first query the character set information from the database side:
Sql> Select Userenv (' language ') Nls_lang from dual;
Nls_lang
----------------------------------------------------
Simplified Chinese_china. Zhs16gbk


Right-click My Computer-Properties-advanced-environment variables-system environment variables:
1> Select "Path"-click "Edit" to add "D:\Oracle\app\YM\product\instantclient_11_2;"
2> Click "New", the variable name is set to "Tns_admin", the variable value is set to "D:\Oracle\app\YM\product\instantclient_11_2;", click "OK";
3> Click "New" and the variable name is set to "Nls_lang" and the variable value is set to "simplified Chinese_china. ZHS16GBK ", click" OK ";
Finally click "OK" to exit.


Start PL/SQL Developer and run without problems.
