Oracle is not installed, and pl/SQL is directly used to connect to oracle server in 3 minutes. Many people, especially those who do not like oracle, must learn from oracle and think that oracle occupies a lot of memory. I do not like to install oracle on physical machines, most of which are windows users, and most developers provide a solution based on the above requirements: www.2cto.com installs the oracle server on the virtual machine, and provides the minimum memory to the virtual machine on the physical machine. Most people use windows, directly to the next installation-free pl/SQL develop so that those who have the above needs can be assured of the following specific steps for the above planning and writing: www.2cto.com ① copy all oci packages from the server installation package to a specific path, for example, E: \ instantclient, pay attention to version issues. Oracle does not support 64-bit oci, that is, you can only copy 32-bit oci, for example:
② Configure tnsnames. ora, the path should be the same, for example: E: \ instantclient \ NETWORK \ ADMIN configuration case: [SQL] orcl = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = 195.167.253.115) (PORT = 1521) (CONNECT_DATA = (SERVICE_NAME = orcl.oracle.com) ③ configure pl/SQL to start PL/SQL Developer. On the logon window, click "cancel" to go to the main interface. Click "Tools"> "Preferences". In the connection, you must configure the following two parameters: Oracle Home: e: \ instantclient OCI Library: e: \ instantclient \ oci. dll example:
So far, pl/SQL dev can work normally.
