Maven İle Oracle JDBC Thin Driver

JDBC Thin Driver vs OCI

Açıklaması şöyle. Yani Java kullanıyorsak JDBC Thin Driver yeterli.

Oracle provides four types of drivers for their database, but I'll only enumerate the two you asked about.

The OCI driver is a type 2 JDBC driver and uses native code to connect to the database. Thus, it is only an option on platforms that have native Oracle drivers available and it is not a "pure" Java implementation.

Oracle's JDBC Thin driver is a type 4 JDBC Driver that uses Java sockets to connect directly to Oracle. It implements Oracle's SQL*Net TCP/IP protocol directly. Because it is 100% Java, it is platform independent ...

Sınıflar

Bazı sınıflar şöyle 

OracleDataSource

OracleConnection

Connection Pool

Oracle Universal Connection Pool kullanılabilir.

Universal Connection Pool - PoolDataSource Sınıfı yazısına bakabilirsiniz.

Universal Connection Pool - PoolDataSource Sınıfı

Giriş

Açıklaması şöyle. Yani 12c'den sonra JDBC sürücüsü de en az 12.1.0.2 olmalı

Prior to 12c (i.e., 12.1.0.1.0), UCP could work with any version of Oracle JDBC driver. With the new pool, UCP 12.1.0.2, it is dependent on Oracle JDBC driver 12.1.0.2.

Örnek

Şöyle yaparız. OracleDataSource sınıfını kullanıyor

import oracle.ucp.jdbc.PoolDataSource;
import java.sql.Connection;
import java.sql.SQLException;

PoolDataSource ds = PoolDataSourceFactory.getPoolDataSource();
ds.setUser("...");
ds.setPassword("...");
ds.setConnectionFactoryClassName("oracle.jdbc.pool.OracleDataSource");
ds.setURL("jdbc:oracle:thin:@exampledb?TNS_ADMIN=/msdataworkshop/creds");
Connecton con = ds.getConnection();

Örnek

Şöyle yaparız.

PoolDataSource pds = PoolDataSourceFactory.getPoolDataSource();

pds.setURL(...);
pds.setUser(...);
pds.setPassword(...);
pds.setConnectionFactoryClassName("oracle.jdbc.pool.OracleDataSource");

//Setting pool properties
pds.setInitialPoolSize(5);
pds.setMinPoolSize(5);
pds.setMaxPoolSize(20);

Connection conn = pds.getConnection();

Şöyle yaparız.

int usedConnectionCount = pds.getBorrowedConnectionsCount();
int availableConnectionCotun = pds.getAvailableConnectionsCount();
