    SAP's Web Application Server 6.2 vs. BEA's WebLogic | existent questions and Pass4sure dumps

    How attain you rate WAS 6.2 from SAP compared to WebLogic from BEA?

    SAP's upcoming Web Application server (WAS) 6.2 is supposed to allow developers to create Java Server pages to access the R/3 application server. This will be accomplished by integrating the Java virtual machine from a Java application server vendor that SAP purchased nearly two years ago.

    However, BEA has been in the Java application server industry for over five years now, and their WebLogic server is a highly respected product. WebLogic is currently seen as the default industry criterion in Java application servers, and includes features designed to back mission captious applications. Using clustering and loadbalancing, you can ensure that your Java applications maintain 24x7x365 availability, and BEA continues to provide innovative technologies such as Web services in each release.

    SAP's Web Application server should be ready for primetime in a year or two, but for now it should be seen as an initial pains into the Entperprise Java infrastructure space. The other component of WAS is the ability to combine ABAP and HTML directives to create dynamic Web applications for SAP. If you necessity to leverage existing ABAP skills to create applications for the Internet, the WAS is simply the only route to go.

    Configuring WebLogic Server 9.x JDBC | existent questions and Pass4sure dumps

    WebLogic Server 9.x provides database connectivity with data sources. A data source is a pool of database connections from which a connection can be obtained. A data source can be configured separately or as a multi-datasource. A multi-data source is collection of data sources. A data source is configured with a JNDI binding. A DataSource kick is obtained with a JNDI lookup. A Connection kick can be obtained from a DataSource kick with the getConnection() method. WebLogic Server provides an administration console to configure a data source. WebLogic Server 9.x includes ilk 4 JDBC drivers from DataDirect for DB2, Informix, Microsoft SQL Server, Sybase, and Oracle databases. JDBC drivers for other databases can be incorporated in the server by including the JAR files for the JDBC drivers in the server classpath.

    novel JDBC features in WebLogic Server 9.0 comprise back for JDBC 3.0, multiple JNDI names for a data source, and back for a Logging ultimate Resource transaction option. SQL Statement Timeout has been added to the connection pool configuration. SecondsToTrustAnIdlePoolConnection and PinnedToThread connection pool properties, which we'll debate below, maintain been added to ameliorate data source performance. The connection request failover feature has been improved. Statistics collection has been added for the different connection parameters for performance diagnostics. novel features maintain been added to WebLogic ilk 4 JDBC drivers and there's novel identity-based connection pooling. Transaction, diagnostic, and security tabs are now Part of the administration console for configuring a data source.

    Setting the EnvironmentDownload WebLogic Server 9.1. To install the application server double-click on the server910_win32 application. Click on the Next button in the BEA Installer. Select Create a novel BEA Home in the select BEA Home Directory frame and specify a directory in the BEA Home Directory field. Click on Next.

Add the MySQL JDBC driver JAR file mysql-connector-java-3.1.11-bin.jar file to the CLASSPATH variable of the <weblogic91>\samples\domains\wl_server\bin\startWebLogic script file. <weblogic91> is the directory in which WebLogic Server 9.1 is installed. Double-click on the <weblogic91>\samples\domains\wl_server\startWebLogic to start the WebLogic examples server.

    Creating a Data SourceA data source is a pool of JDBC connections from which a connection can be obtained with the getConnection() manner of a DataSource object. In this section we'll create a data source in the administration console. Access the administration console with the URL http://localhost:7001/console. In the administration console select the node Services>JDBC>DataSources.

    To create a novel JDBC data source click on novel in the Data Sources table (see motif 1).

    Specify a data source cognomen in the Create a novel JDBC Data Source frame and a JNDI cognomen for the data source. A data source is bound on a JNDI tree with a JNDI name. Select a Database Type. We'll create a data source with the MySQL database. Select MySQL as the Database Type. Select MySQL's driver (Type 4) as the database driver and click on Next (see motif 2).

    A data source can be configured with any of the commonly used databases. WebLogic provides ilk 4 JDBC drivers from DataDirect for DB2, Informix, Oracle, SQL Server, and Sybase. The DataDirect drivers are pre-installed in the <weblogic9.1>/server/lib directory (see motif 3). The different JDBC ilk 4 drivers included with WebLogic Server are listed in Table 1.

    Databases other than those for which a JDBC driver is included can also be selected. If a JDBC driver other than the WebLogic driver is selected add the driver zip/JAR file to the CLASSPATH variable in the startWebLogic script (see motif 4).

    In the Transaction Options frame the transaction attributes of the data source are specified. If a XA driver is selected global transactions are automatically supported with the two-phase confide transaction protocol. A global transaction, or a distributed transaction, is a transaction that involves two or more transactions over multiple (or single) resource managers (a RDBMS database is a resource manager). A global transaction is managed by a Transaction Manager using JTA. For a non-XA data source to back global transactions, check the Global Transactions checkbox. Select the protocol that supports global transactions. The different transaction protocols are listed in Table 2.

    In the Transaction Options page click on Next (see motif 5).

    In the Connection Properties frame specify the Database Name, test for the default database instance. Specify Host cognomen as localhost, Port as 3306, and user cognomen as root. A password isn't required for the root username. Click on the Next button (see motif 6).

    In the Test Database Connection frame the driver class name, connection URL, and username for the MySQL database are specified. Click on the Test Database Configuration button to test the connection with the database (see motif 7).

    A message gets displayed indicating if a connection has been established. If database doesn't pickup connected an mistake message gets displayed. Click on the Next button.

    In the Select Targets frame select a server where the data source will be deployed. To deploy to the examples server, select examplesServer and click on the Finish button (see motif 8).

    A data source gets configured and added to the Data Sources table (see motif 9).

    Click on the Activate Changes button to construct the data source available to applications in the server.

    Configuring a Data SourceIn this section the data source created in the ultimate section will be configured. Select the data source to configure in the Data Sources table. Select the Configuration tab (selected by default). In the Configurations frame the data source JNDI cognomen can be modified (see motif 10).

    The other configuration options for a data source are listed in Table 3.

    To configure the connection pool associated with data source select the Connection Pool link. Initial capacity, maximum capacity, and capacity increment can be set in the connection pool configuration (see motif 11).

    Some of the connection pool settings are listed in Table 4.

    The transaction protocol settings can be configured with the Transaction link. Monitoring statistics can be collected with the Diagnostics link (see motif 12).

    Some of the data source profiles that can may be collected are listed in Table 5.

    To monitor a data source select the Monitoring tab. To administer the WebLogic Server instances to which the data source is deployed select the Control tab. In a deployed server instance the statement cache can be cleared and server can be suspended or shut down.

    Creating a Multi-Data SourceA multi-data source is an abstract group of data sources, which provides failover and load balancing around data sources. A multi-data source has a JNDI binding similar to a data source. To create a multi-data source click on the Services>JDBC>Multi Data Sources link in the administration console (see motif 13).

    In the Multi Data Sources table click on the novel button to create a novel multi-data source (see motif 14).

    In the Configure the Multi Data Source frame specify a data source cognomen and a JNDI cognomen for the data source. Select the algorithm ilk as Failover or Load Balancing. Click on the Next button (see motif 15).

    In the select Targets frame select the examplesServer or another server to deploy the multi-data source to. Click on the Next button (see motif 16).

    In the Select Data Source ilk frame select XA driver for an XA data source or a non-XA driver for a non-XA data source. Click on the Next button (see motif 17).

    In the Add Data Sources frame add data sources from the Available list to the Chosen list. If novel data sources are required click on the Create a novel Data Source button. Then click on the Finish button (see motif 18).

    A novel data source gets configured and added to the Multi Data Sources table. Click on the Activate Changes button to construct the data source available to applications (see motif 19).

    A multi-data source can be configured by selecting the multi-data source link. The targets to which the multi-data source is deployed can be configured with the Targets tab. The data sources in the multi-data source can be configured with the Data Sources link in the Configuration tab. The multi-data source JNDI cognomen can be modified in the Configuration>General frame. The Algorithm ilk specifies the algorithm used to select a data source from which a connection is obtained. If the algorithm ilk is Failover, connection requests are sent successively to the data sources in the list until a connection is obtained or the finish of the data source list is reached. If the algorithm ilk is a Load Balancing connection request the load is distributed evenly over the data sources in the list. If load balancing is the selected connection, failover is also provided with the connection requests being sent to different data sources in the list until a connection gets established or the finish of the data source list is reached (see motif 20).

    A multi-data source also provides the Failover Request If Busy, Failover Callback Handler, and Test Frequency settings. For a multi-data source with the Failover algorithm if Failover Request If diligent is selected the connection request is sent to the next data source if entire the connections in a data source are busy. The Failover Callback Handler specifies the application class to wield the callback sent when a multi-data source is ready to transmit a Failover connection request to another data source. Test Frequency specifies the interval in x number of seconds after which connections are tested. If a connection fails the connection is closed and reopened. If the connection fails again the connection is closed (see motif 21).

    Performance Tuning JDBCSome of the JDBC design considerations to ameliorate performance comprise the selection of the JDBC driver. The WebLogic ilk 4 JDBC drivers from DataDirect provide comparable performance. The connection pooling provided by WebLogic Server data sources improves performance by keeping a pool of connections available for JDBC applications. Connection don't maintain to be opened and closed for each client. Tune the number of connections by setting the Initial Capacity equal to Maximum capacity in a connection pool. Maximize the reuse of connections rather than closing and opening connections. A connection may be pinned to a thread by setting the PinnedToThread configuration pool attribute. immediate connections after a connection is not required.

    Test Connections on Reserve tests connections before making a connection available to a client, but connection testing can reduce performance. To preclude frequent connection testing set the connection pool assign Seconds to faith an Idle Pool Connection, which specifies the number of seconds for which a connection returned by a client isn't tested with a SQL query. Data source performance can be improved by selecting Row Prefetch Enabled and an optimal pre-fetch size in configuring a data source. Row pre-fetching improves performance by fetching multiple rows from the server to an external client. Caching statements improves performance by reusing statements rather than creating novel ones. Statement caching is specified in the connection pool configuration.

    Developing a JDBC JSP ApplicationIn this section we'll develop a JSP application to retrieved data from a MySQL database table with the data source configured in the Creating a Data Source section. First, create an illustration database table in the MySQL database. Access the MySQL database with the command mysql.


    To create a database table in the test database instance login to the test database.

    mysql>use test

    Create a table, Catalog with the SQL script in Listing 1.

    Create a JSP, catalog.jsp. In the JSP import the java.sql, javax.sql, java.util, and javax.naming packages.

    <%@ page



    Create a InitialContext object.

    InitialContext ctx=new InitialContext();

    Create a DataSource kick from the JNDI cognomen of the MySQL data source.

    DataSource ds=(DataSource)ctx.lookup("jdbc/MySQLDS");

    Obtain a JDBC connection from the DataSource object.

    Connection connection=ds.getConnection();

    Create a Statement kick from the Connection object.

    Statement stmt=connection.createStatement();
