Users of Oracle databases can specify connection strings: on the command line (as in: sqlplus scott/tiger@connection_string ) via environment variables ( $TWO_TASK in Unix-like environments; %TWO_TASK% in Microsoft Windows environments) [1] in local configuration files (such as the default $ORACLE_HOME/network/admin.tnsnames.ora) [2]
Users initiate a connect request by passing a user name and password along with a network service name in a connect string for the service to which they want to connect: CONNECT username/password@net_service_name
List of tz database time zones. The tz database partitions the world into regions where local clocks all show the same time. This map was made by combining version 2023d with OpenStreetMap data, using open source software. [1] This is a list of time zones from release 2024a of the tz database. [2]
Transparent Network Substrate (TNS), a proprietary Oracle computer-networking technology, supports homogeneous peer-to-peer connectivity on top of other networking technologies such as TCP/IP, SDP and named pipes. TNS operates mainly for connecting to Oracle databases .
At the application level, CockroachCloud provides the connection string and parameter information that applications need to connect to the database cluster through code using PostgreSQL database ...
Connections are built by supplying an underlying driver or provider with a connection string, which is a way of addressing a specific database or server and instance as well as user authentication credentials (for example, Server=sql_box;Database=Common;User ID=uid;Pwd=password; ).
In computing, a data source name ( DSN, sometimes known as a database source name, though "data sources" can comprise other repositories apart from databases) is a string that has an associated data structure used to describe a connection to a data source.
Connection conn = DriverManager.getConnection( "jdbc:somejdbcvendor:other data needed by some jdbc vendor", "myLogin", "myPassword"); try { /* you use the connection here */ } finally { //It's important to close the connection when you are done with it try { conn.close(); } catch (Throwable e) { /* Propagate the original exception ...
For example, if F = { a, b, c, d, e, f, g, h }, and R = { 1, 2, 3, 4, 5, 6, 7, 8 }, then FR denotes the set of all chess board coordinates in algebraic notation, while e R denotes the set of all coordinates of the kings' file . In this context, sets of strings are often referred to as formal languages.
In software engineering, a connection pool is a cache of database connections maintained so that the connections can be reused when future requests to the database are required. [1] Connection pools are used to enhance the performance of executing commands on a database.
