PL/SQL Developer connect to the Oracle (64Bit) diagram installed on Win7

PL/SQL Developer connects to the Oracle (64Bit) diagram installed on Windows 7. Thanks to the continuous update of hardware technology, Windows 7 has gradually become the mainstream and the computer memory has gradually increased, to make full use of memory resources (because 32 is the system can only use about 3 GB of memory) and improve system performance, many people begin to use Win7 (64Bit) systems. The 64-bit Oracle database is installed on a 64-bit system, but there is no corresponding 64-bit PL/SQL Developer. In this case, PL/SQL Developer cannot be used for direct connection, therefore, other methods are required to achieve the connection. The following describes how to implement connections. Www.2cto.com 1. Download the Oracle client: Workshop.

Select the first Instant Client for Microsoft Windows (32-bit) for download. Do not download 64bit. I have tried it and cannot implement the connection. 2. Configure the Oracle client to download and decompress it without installation. For example, extract it ...... under the \ TOOLS_APP directory, create a two-tier Folder \ NETWORK \ ADMIN under the instantclient_11_2 directory, and then create a tnsnames under the ADMIN folder. add the following content to the file: www.2cto.com [plain] ORACLE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521 )) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORACLE) LISTENER_ORACLE = (ADDRESS = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521) ORACLR _ CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1521) (CONNECT_DATA = (SID = CLRExtProc) (PRESENTATION = RO ))) the above content can be copied here: E: \ OracleDB \ app \ MuLing \ product \ 11.2.0 \ dbhome_1 \ network \ admin \ tnsnames. ora. Www.2cto.com 3. Install PL/SQL Developer and install the downloaded PL/SQL Developer (not downloaded on the Internet by yourself). However, note that the installation path cannot contain parentheses, do not install Files in the C: \ Program Files (x86) directory. 4. Configure PL/SQL Developer: After the installation is complete, run PL/SQL Developer. The logon form that appears cannot be logged on. Click the Calcel button, in this case, the system enters the non-Logon status.

Configure the relevant information and configure the information of the decompressed package:

5. Restart PL/SQL Developer to log on.

Enter the relevant information to log on. 6. Verify that an SQL statement has been written to Oracle for verification. The following results are displayed in the query, indicating that the connection is successful.
