QUESTION 101 A critical error is occuring on a production node causing the JVM logs to rapidly fill up . Which resolution should the WebSphere administrator take as the first step for troubleshooting? The logs are self-managing and can roll over based on time ro file size, so simply opening the logs with a text editor will ensure that new log files are created. Removing the application server from the network, either administratively or physically, is necessary to stop the JVM processing. Stopping the JVM process from the command line, removing the application administratively thru the console and restarting the JVM will allow processing to continue on other applications. The administrator should remove the failing application server from user requests, thereby stabilizing the application server so that troubleshooting can begin.

QUESTION 11 An application server is using data source connections being managed thru connection pooling.How ever, the server is logging database errors resulting from lack of connections. In this context, what applies to tuning database connections? Data sources are abstracted from the JDBC drivers to permit database upgrades without impacting the application logic. The administrator should decrease the connection timeout value. The connection pool is managed by the application server container, so in addition to increasing the connection setting, additional connections allowed must be configured on the database. The data sources are released at the end of the commit phase when using Type 4 JDBC drivers. New  connections will be created upon the next database access. It is necessary to tune the applications before tuning WebSphere application server. Connections not returned to the pool are often caused by programs not closing connections properly. Answer: D...

Java Database Connectivity JDBC technology is an API (included in both J2SE and J2EE releases) that provides cross-DBMS connectivity to a wide range of SQL databases and access to other tabular data sources, such as spreadsheets or flat files. With a JDBC technology-enabled driver, you can connect all corporate data even in a heterogeneous environment

Application Server: As for the application server, according to our definition, an application server exposes business logic to client applications through various protocols, possibly including HTTP. While a Web server mainly deals with sending HTML for display in a Web browser, an application server provides access to business logic for use by client application programs. The application program can use this logic just as it would call a method on an object  ####################################################################### Web Server : A Web server handles the HTTP protocol. When the Web server receives an HTTP request, it responds with an HTTP response, such as sending back an HTML page. To process a request, a Web server may respond with a static HTML page or image, send a redirect, or delegate the dynamic response generation to some other program such as CGI scripts, JSPs (JavaServer Pages), servlets, ASPs (Active Server Pages), server-side JavaScri...

the naming of connection factory is independent of the name specified by JMS client. This is made possible by WAS (Web sphere application server) with its resource references. It isolates the application from object names. This feature is important because it gives us the flexibility to change the administered object without changing the JMS client code

CHANNEL specifies the name of the server connection channel. Generally this is Web Sphere MQ network abstraction. The default standard used by CHANNEL is SVRCONN which is the server connection channel. This server is generally used to communicate to the queue manager by the client

Web sphere MQ and Web Sphere Business integration manager Broker are very useful in providing Java messaging services to wide range of clients (publisher –subscribe, point to point). Java classes are chiefly responsible for translating the API calls to API`s defined by web sphere. It is very useful to have knowledge of Web sphere MQ for proper configuration

This feature is very useful in instant messaging across different clients through intranet and internet. This supports high volume and high performance across different clients. It uses the concept of light weight transport which is again based on IP rather than the queue process.

Compute grid is also known as Web sphere batch. Web sphere extended deployment offers a Java batch processing system called as Compute Grid. This forms an additional feature to Web sphere network environment. Various features are provided which help a developer to create, manage and execute batch jobs.

Managing singletons will be a thing of the past and it also provides hot recovery of singletons which makes you forget about your GC collected singletons. Transaction logs can stored on a shared file system. For clustering run time operations deployment manager`s role was eliminated. J2EE failover support and cell configuration support is also present

A caching proxy can be configured in forward direction or as a proxy. Content requested by the user is cached by edge before sending or adhering to the query. Page fragments arising from JSP or servlets are cached by Edge and the caching process is slow. Performance and scalability of J2EE applications can be increased by edge

Web sphere almost reduces the work of server administrator as he can manage load on servers efficiently without any hassles. It also gives him flexibility to divide the load and applications among different server farms. He can also predict about the incoming load on servers. Email alerts, restart options, memory leak detection, etc

Asymmetric clustering applications are primarily used in electronic trading systems employed in banks. Some of the features are, partitions can be declared during run time and are usually run on a single cluster at a time. Work specific to a particular can be routed to that cluster
