Geronimo plug -in, connector 1.6 in Java class library 1.6: Affairs management of optimizing application performance (JTA11) skills
introduction:
As the needs of enterprise applications are becoming more and more complicated, the performance optimization of transaction management is becoming more and more important.The Geronimo plug -in and connectors in Java provides some powerful functions and skills to help developers optimize application performance and better manage affairs.This article will introduce some techniques to use the Geronimo plug -in and connectors 1.6 to optimize the performance of the application.
1. Use batch operations
When performing database operations, multiple similar operations often need to be performed.In this case, using batch operations can effectively improve performance.Here are examples of batch operations using Geronimo plug -in and connectors 1.6:
import javax.resource.spi.work.Work;
import javax.transaction.UserTransaction;
public class BatchWork implements Work {
private UserTransaction utx;
public BatchWork(UserTransaction utx) {
this.utx = utx;
}
@Override
public void run() {
try {
utx.begin();
// Batch execution database operation
// ...
utx.commit();
} catch (Exception e) {
// Roll back transactions
try {
utx.rollback();
} catch (Exception ex) {
// Treatment of transaction is abnormal
}
// Treatment abnormalities
}
}
@Override
public void release() {
// Release resources
}
}
Using the above code, multiple database operations can be encapsulated in a batch task and executed in one transaction.This can avoid opening and submitting transactions many times to improve performance.
2. Enable secondary cache
Geronimo plug -in and connectors 1.6 support enable secondary cache to improve application performance.The secondary cache can cache the query results in the database operation to avoid frequent access to the database, thereby improving the performance of the application.The following is an example of using the Geronimo plug -in and connectors 1.6 to enable the secondary cache:
import org.apache.geronimo.connector.outbound.GenericConnectionFactory;
import org.apache.geronimo.connector.outbound.connectionmanagerconfig.TransactionSupport;
import org.apache.geronimo.connector.outbound.pool.DefaultThreadPool;
import org.apache.geronimo.connector.outbound.pool.PoolingAttributes;
public class CacheExample {
public static void main(String[] args) {
GenericConnectionFactory factory = new GenericConnectionFactory();
// Configure the connection pool
PoolingAttributes poolAttributes = new PoolingAttributes();
porattributes.setcacheSize (100); // Set the cache size
porattributes.setBlockingtimeout (3000); // Set the blocking timeout time
poolattributes.setIdIdInuteminutes (15); // Set free time overtime time
DefaultThreadPool threadPool = new DefaultThreadPool();
Threadpool.setmaxpoolsize (10); // Set the maximum connection number
Threadpool.setminPoolsize (3); // Set the minimum connection number
factory.setConnectionManager(poolAttributes);
factory.setConnectionFactory(new MyConnectionFactory());
Factory.SettransactionSupport (transactionSupport.transaPPortlevel.
factory.setThreadPool(threadPool);
// Use connecting the factory to perform database operations
// ...
}
}
In the above example, the cache size of the connection pool can be used to enable the secondary cache and set the appropriate connection pool attribute.
in conclusion:
By using the functions and skills provided by the Geronimo plug -in and connectors 1.6, developers can optimize the performance of the application and better manage the affairs.The use of batch operations and enable secondary cache is the two important techniques to improve performance.It is hoped that the content of this article will help developers who use the Geronimo plug -in and connectors 1.6 for transaction management.
