Windows7-64bit installation oracle11g

① first problem encountered: physical memory when installing Oracle ... Installation Prerequisites Check all failed to install, show NA

　　cause : The Oracle execution prerequisite check is dependent on the C $ share, and Win7 shuts down this for security by default, causing the check to pass.

　　workaround : Ensure that the Server service in the service is functioning properly, then enter net share c$=c in the cmd command console: OK, (search cmd, right-click Cmd.exe Run as Administrator)

If you still cannot pass the prerequisite check, modify the computer name, account name, domain, or workgroup name in English, and make sure that the network connection is healthy (although it is not necessary to connect to the network during installation)

②pl/sql Developer 8 has only 32 bits so you need to install the Oracle client "Instantclient-basic-nt-11.2.0.4.0.zip" This client is 32-bit. (Oracle is 64-bit)

Directly unzip to any place in the "Instantclient_11_2" folder to create "Network/anmin" folder and then put "D:\Sun\product\11.2.0\dbhome_1\NETWORK\ADMIN"

The "Tnsnames.ora" file is copied to the newly created folder.
