After Oracle completes the installation, services will be registered in the system. Among the registered services, the following two services must be started, otherwise Oracle will not be able to use normally:
(1) OracleOraDb11g_home1TNSListener: Indicates the listening service. If the client wants to connect to the database, this service must be turned on. This service also works during program development .
(2) OracleServiceORCL: Indicates the main service of the database, naming rules: OracleService database name. This service must be turned on, otherwise Oracle cannot be used at all.

A. Installation notes for 32-bit Oracle 11g Client (win32_11gR2_client.zip) (client installation):
When selecting the installation type, select "Administrator", as shown below:
The other steps are similar to installing the server side.
B. Notes on PL/SQL Developer installation:
Configure oracle's environment variables:
TNS_ADMIN -- F:\app\kevin\product\11.2.0\dbhome_1\NETWORK\ADMIN
As shown below: (If this environment variable is not matched, the plsql tool cannot connect to the database instance)
Before installing PL/SQL, you need to install the Oracle client first.
My system environment:
1. 64-bit Windows 7 Ultimate
2、64位Oracle 11g R2 DB
3. 32-bit Oracle 11g Client (64-bit Oracle 11g Client will make an error)
4、PL/SQL Development 8.0.4
Notice:
(1) PL/SQL Development should not be installed in the default C:\Program Files (x86) directory, otherwise an error will be reported because the path with () cannot be parsed.
(2) When the 64-bit Oracle 11g Client is installed on the Oracle client, an error will be prompted when PL/SQL Developer is started.
Reason: oci.dll is 64-bit, the 32-bit application PL/SQL Developer cannot be loaded, you can install a 32-bit Oracle Client to solve it.
=================================================
1. Install 64-bit oracle11g
Second, install the 32-bit oracle11g client
Third, install pl/sql developer. Set oracle home and oci library in tools->perference->connection.
如：oracle home : C:\app\Administrator\product\11.2.0
oci library : C:\app\Administrator\product\11.2.0\client_1\bin\oci.dll
