connecting remote Oracle is to use OCI. The Oracle Calling interface (Oracle call interface, OCI) provides a set of interface functions that can be accessed from an Oracle database, which can be accessed by invoking the third-generation programming language for the purpose of accessing the Oracle database.

, computers on external networks cannot be connected to virtual machines by default. Therefore, virtual machines cannot provide services such as WEB browsing. Host-only (Host machine virtual network adapter): This mode allows virtual machines to communicate with the Host machine, but this virtual adapter does not connect to any external network, only special software such as a proxy server can be set up on the host machine to connect the virtual adapter to the physical adapter. In fact, virtual
This article introduces a simple example of connecting PHP to the MYSQL database in the LAN. If you need it, refer to it.
The Code is as follows:
$ Conn = mysql_connect ('192. 168.0.220 ', 'root', '123 ');If (! $ Conn) echo "failed! ";Else echo "successful! ";// SQL statement used to extract information from the table$ SQL = "SELECT * FROM user where userName = '$ user_name '";// Execute SQL query$ Result = mysql_db_query ('info', $ SQL, $ conn )
survival, maybe it is still dependent on the next. In fact, I am glad that at least I have changed the technical direction when I first entered the society, and I have entered a more popular field. There are various great gods around me, I can only work harder and learn more. My friends said, "persistence is victory." I am going to continue.
