Lesson - 27 : Hibernate - Built-in connection pooling in Hibernate
 
18:08
Hibernate – Built-in Connection Pooling in Hibernate: 1. If a java program wants to obtain a connection with a database then java API as provided or JDBC API as provided two ways. A) java.sql.DriverManager class B) javax.sql.DataSource interface 2. If a java program want to get direct connection with the database then we use DriverManager class. 3. The connection returned by DriverManager class is a nonreusable connection. The non reusable connections will increase the burden on a database. 4. To overcome the above problem we got connection pooling technique in java. 5. In connection pooling a group of reusable connections(pooled connections) are stored in a pool and the connections are provided to the clients whenever required. 6. To obtain a connection from a connection pool we use DataSource interface in a java program In hibernate connection pooling mechanism is divided into three types 1. Built-in connection pooling / jdbc connection pooling 2. Standalone connection pooing/Third party connection pooling 3. Server side connection pooling Built-in connection pooling / jdbc connection pooling : 1. Hibernate by default comes with automatic connection pool. This is also called jdbc connection pool. 2. As a programmer we are allowed to set the maximum pool size for hibernate built- in connection pool 3. If you want to set maximum pool size then we need to configure connection pool size property in hibernate.cfg.xml file 4. <property name=“hibernate.connection.pool_size”>10</property> 5. The built- in connection pool of hibernate is only for testing purpose, but it should not be used in real time application (production.system) Configurations: <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:xe</property> <property name="hibernate.connection.pool_size">50</property> <mapping resource="Payment.hbm.xml"/> </session-factory> </hibernate-configuration> Hibernate Examples Project Github Link : https://github.com/SadaLearningHub1/Hibernate-Projects

26:23
Advanced Java Tutorial :adv java: JDBC Connection Pool and Its Utilization | java Database connectivity :JDBC Connection Pooling: JDBC Connection pool is a factory that contains set of readily available JDBC connection objects. Using JDBC Connection pool we can make more clients interacting with Database by using minimum JDBC connection objects. JDBC DataSource object represent JDBC Connection pool that means to access connection objects from connection pool we need to use DataSource object. DataSource Object means its the object of a class that implements javax.sql.DataSource interface There are two types of JDBC connection objects: ----------------------------------------------- 1) Direct Connection object: Created by programmer (manually) Ex. Class.forName("oracle.jdbc.driver.OralcleDriver"); Connection con=DriverManager.getConnection("url","user","pass"); 2)Pooled Connection object: It is the object that is collected from JDBC connection pool using JDBC DataSource object. Two types of JDBC connection pools: ----------------------------------- 1) DriverManaged JDBC Connection Pool: (Driver itself maintains connections) -Suitbale for standalone application. -Uses Type 1/2/4/5 drivers directly. -Only few JDBC drivers support this kind of JDBC connection pools ex. Oracle OCI, thin driver 2) Server managed JDBC connection pool: -Suitable for web applicatoin which runs on web/proxy server. -Uses type 3 with type 1/2/4/5 JDBC drivers. -Suitable for 3-tier/n-tier applicatoin which runs on server environment. Example JDBC application on Oracle thin driver to manage the JDBC connection pool for Oracle: ========================================================================= import java.sql.*; import javax.sql.*; import oracle.jdbc.pool.*; public class ConnectionPoolTest { public static void main(String[] args) throws Exception { //create the Empty jdbc datasource object representing driver managed Connection pool for oracle OracleConnectionPoolDataSource ds=new OracleConnectionPoolDataSource(); //give the details to create JDBC connection objects in the above empty datasource connection pool i.e 'ds' ds.setDriverType("thin"); ds.setServerName("localhost"); ds.setPortNumber(1521); ds.setServiceName("orcl"); ds.setUser("scott"); ds.setPassword("boss"); //Upto here JDBC connection pool ready with JDBC connection object //get one JDBC connection object from connnection pool Connection con=ds.getConnection(); // Write the JDBC persistant logic Statement st=con.createStatement(); ResultSet rs=st.executeQuery("select * from student"); while(rs.next()){ System.out.println(rs.getInt(1)+"\t"+rs.getString(2)+"\t"+ rs.getString(3)); } rs.close(); st.close(); con.close(); // --- returns/release the conection object back to JDBC connection pool } }

connection pool in weblogic server
 
03:47
JDBC Connection Pooling JDBC connection pooling is conceptually similar to any other form of object pooling. Database connections are often expensive to create because of the overhead of establishing a network connection and initializing a database connection session in the back end database. In turn, connection session initialization often requires time consuming processing to perform user authentication, establish transactional contexts and establish other aspects of the session that are required for subsequent database usage. Additionally, the database's ongoing management of all of its connection sessions can impose a major limiting factor on the scalability of your application. Valuable database resources such as locks, memory, cursors, transaction logs, statement handles and temporary tables all tend to increase based on the number of concurrent connection sessions. All in all, JDBC database connections are both expensive to initially create and then maintain over time. Therefore, as we shall see, they are an ideal resource to pool. If your application runs within a J2EE environment and acquires JDBC connections from an appserver defined datasource then your application is probably already using connection pooling. This fact also illustrates an important characteristic of a best practices pooling implementation -- your application is not even aware it's using it! Your J2EE application simply acquires JDBC connections from the datasource, does some work on the connection then closes the connection. Your application's use of connection pooling is transparent. The characteristics of the connection pool can be tweaked and tuned by your appserver's administrator without the application ever needing to know. If your application is not J2EE based then you may need to investigate using a standalone connection pool manager. Connection pool implementations are available from JDBC driver vendors and a number of other sources.

Lesson - 28 : Hibernate - Third party connection pooling in Hibernate

Hibernate – Built-in Connection Pooling in Hibernate: 1. If a java program wants to obtain a connection with a database then java API as provided or JDBC API as provided two ways. A) java.sql.DriverManager class B) javax.sql.DataSource interface 2. If a java program want to get direct connection with the database then we use DriverManager class. 3. The connection returned by DriverManager class is a nonreusable connection. The non reusable connections will increase the burden on a database. 4. To overcome the above problem we got connection pooling technique in java. 5. In connection pooling a group of reusable connections(pooled connections) are stored in a pool and the connections are provided to the clients whenever required. 6. To obtain a connection from a connection pool we use DataSource interface in a java program In hibernate connection pooling mechanism is divided into three types 1. Built-in connection pooling / jdbc connection pooling 2. Standalone connection pooing/Third party connection pooling 3. Server side connection pooling Standalone connection pooing/Thirdparty connection pooling Hibernate has recommended to use one of the following two third party connection pool. When hibernate is used in a standalone or desktop project in java 1. C3p0 connection pool 2. Proxool connection pool C3p0 connection pool Configuration : <hibernate-configuration> <session-factory name=""> ... <property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property> <property name="hibernate.c3p0.max_size">10</property> <property name="hibernate.c3p0.min_size">3</property> ... </session-factory> </hibernate-configuration> C3p0 connection pool : 1. Cp0is an open source third party connection pool maintained by sourceforege.net. 2. If we configure c3p0 connection pool related properties in hibernate.cfg.xml file then internally hibernate itself creates a c3p0 connection pool and obtains connections from that pool . 3. The c3p0 connection pool properties required in hibernate.cfg.xml file are A) hibernate .connection.provider_classs B) hibernate.c3p0.min_size C) hibernate.c3p0.max_size 4. <property name=' hibernate .connection.provider_class'>org.hibernate.connection.c3p0ConnectionProvider</property> <property name=' hibernate.c3p0.min_size'>3</property> <property name=' hibernate.c3p0.max_size'>10</property> 5. To test c3p0 connection poolin a hibernate application do the following A) In hibernate.cfg.xml file of fist application(application1), add the above c3p0 connection pool properties. B) set c3p0-version.jar in classpath apart from the remaining jar files of hibernate. Proxool connection pool Configuration : <hibernate-configuration> <session-factory name=""> ... <property name="hibernate.proxool.xml">Proxool</property> <property name="hibernate.proxool.pool_alias">abcd</property> <property name="hibernate.connection.provider_class">org.hibernate.connection.ProxoolConnectionProvider</property> ... </session-factory> </hibernate-configuration> 1. It is another third party connection pool maintained by sourceforege.net. 2. This third party connection pool is also internally created by hibernate but we need to configure it's required properties into hibernate.cfg.xml. 3. In proxool connection pool we need to construct a separate xml file with anyname.xml and we need to configure the following information in that xml file. A) Pool alias name. B) Connection properties C) Maximum pool size 4. In proxool, minimum pool size is always 1. it is not possible to set user defined minimum size of the pool. 5. In hibernate.cfg.xml file, we need to configure the following proxool related properties A) hibernate.proxool.xml B) hibernate.proxool.pool_alias C)hibernate.connection.provider_class Hibernate Examples Project Github Link : https://github.com/SadaLearningHub1/Hibernate-Projects

JDBC has been around for a long time but because the database interaction happens through higher abstraction API (such as JPA/Hibernate or jOOQ), it’s easy to forget that the actual communication plays by the database driver and the database engine rules. This presentation goes through the most common sources of performance bottlenecks: database connection management, batch updates, statement caching, result set fetching and concurrency control mechanisms with practical references for the most common database systems: Oracle, SQL Server, PostgreSQL and MySQL.

Tuning RDS & JDBC For High-Performance Java Persistence
 
03:43
In this series I cover many high-performance RDS and JDBC characteristics and settings that will enable you to create truly scalable Java persistence applications . I cover: - Importance of Master, Slave & Read replica databases and the role they play. - Why large connection pools per application does not mean better performance - How large numbers of active connections across all application nodes does not mean better performance - Why connection pools are great and how to use the fastest connection pool Hikari-CP at scale. - Prepared Statement Database Caching (In the Database) - Prepared Statement client-side Caching (JDBC) - Importance of setting the Fetch-Size when using JDBC for queries - Major importance of batch transactions when using JDBC - Using multi-value inserts and tuning PostgreSQL for multi-value inserts. - Transaction Isolation Levels - Pessimistic and Optimistic locking for scalability - Indexes for retrievals and why you should remove redundant indexes. - Best practise connection pooling in AWS Lambdas when connecting to AWS RDS or a relational database (From my experience) - Closing open resources such as connections, preparedstatements etc. - Physical location of your database and applications and latency introduced. - Why i switched from MyBatis to use Jooq and raw JDBC for performance I hope you enjoy the series!!! Till part 1 soon. Philip :)
