See Using tnsnames. Specifies either the IP address or the server name if your network supports named servers of the Oracle server. For example, Specifies whether the connection is established using a shared or dedicated server process UNIX or thread Windows. If set to Shared, the server process to be used is retrieved from a pool. The socket connection between the client and server is made to a dispatcher process on the server. This setting allows there to be fewer processes than the number of connections, reducing the need for server resources.
Use this value when a server must handle many users with fewer server resources. If set to Dedicated, a server process is created to service only that connection.
The socket connection is made directly between the application and the dedicated server process or thread. When connecting to UNIX servers, a dedicated server process can provide significant performance improvement, but uses more resources on the server. When connecting to Windows servers, the server resource penalty is insignificant.
Use this value if you have a batch environment with low numbers of users. If unspecified, the driver uses the server type set on the server. The database service name that specifies the database used for the connection. The service name is a string that is the global database name-a name that typically comprises the database name and domain name. For example:. The Oracle System Identifier that refers to the instance of the Oracle database running on the server. This property is mutually exclusive with the ServiceName property.
The path and filename to the tnsnames. The tnsnames. Using a tnsnames. The value of this property must be a valid path and filename to a tnsnames. If this property is specified, do not specify the following properties to prevent connection information conflicts:.
If any of these properties are specified in addition to this property, the driver generates an exception. The Oracle net service name used to reference the connection information in a tnsnames.
The value of this property must be a valid net service name entry in the tnsnames. The case-insensitive default user name used to connect to your Oracle database. A user name is required only if security is enabled on your database.
If so, contact your system administrator to obtain your user name. Operating System authentication is not currently supported by the Oracle driver. The Oracle driver allows you to retrieve basic connection information from a tnsnames. NET Providers. Windows PowerShell Cmdlets offering straightforward command-line access live data.
Straightforward Apps for data replication with on-premise and cloud databases. Features Compatible with Oracle Database Access Oracle through standard Java Database Connectivity. Support for bit and bit operating systems. JDBC Driver Performance With traditional approaches to remote access, performance bottlenecks can spell disaster for applications.
Common issues include: Network Connections - Slow network connections and latency issues are common in mobile applications. Service Delays - Delays due to service interruptions, resulting in server hardware or software updates. Large Data - Intentional or unintentional requests for large amounts of data.
Disconnects - Complete loss of network connectivity. Smart Caching Smart caching is a configurable option that works by storing queried data into a local database. Each row returned by the query will be inserted or updated as necessary into the corresponding table in the cache database.
Explicit Cache - Cache only on demand. Developers decide exactly what data gets stored in the cache and when it is updated. Explicit caching provides full control over the cache contents by using explicit execution of CACHE statements. No Cache - All requests access only live data and no local cache file is created.
Add a new Data Connection from the server explorer and select the Oracle Data Source Configure the basic connection properties to access your Oracle account data. After configuring the connection, explore the tables, views, and stored procedures provided by the Oracle JDBC Driver. These constructs return live Oracle data that developers can work with directly from within the IDE. Access Oracle Database from virtually any application that can access external data.
Offers advanced wire-protocol SSL security for remote connectivity. There are two tabs you can use to connect. Free Download DbSchema When the download finished please follow this steps:. This will be the name of this specific connection to the database. Each database can have multiple connection and authentication methods. Switch to a different method from the dropdown menu. At the end of your JDBC program, it is required explicitly to close all the connections to the database to end each database session.
However, ifyou forget, Java's garbage collector will close the connection when it cleans up stale objects. Relying on the garbage collection, especially in database programming, is a very poor programming practice. You should make a habit of always closing the connection with the close method associated with connection object. To ensure that a connection is closed, you could provide a 'finally' block in your code.
A finally block always executes, regardless of an exception occurs or not. Explicitly closing a connection conserves DBMS resources, which will make your database administrator happy. Import JDBC Packages The Import statements tell the Java compiler where to find the classes you reference in your code and are placed at the very beginning of your source code. Approach I - Class. The following example uses Class.
Using a Database URL with a username and password The most commonly used form of getConnection requires you to pass a database URL, a username , and a password : Assuming you are using Oracle's thin driver, you'll specify a host:port:databaseName value for the database portion of the URL.
