D: Elastic message overflow is the ability for WebLogic JMS to take advantage of solid state disks, especially on Exalogic, for paging of JMS messages. This is especially important in spikes of traffic. Access to SSD is much faster than disks or the database, which are used for true persistent storage. This speed of writing and reading enables the system to absorb the spikes in traffic.

A:

* Troubleshooting Slow Response Time from the Client and Low Database Usage

These symptoms are usually caused by a bottleneck upstream of the database, perhaps in the JDBC connectionpooling. Monitor the active JDBC connections in the WebLogic Console and watch for excessive waiters and wait times; increase the pool size, if necessary.

* Attribute: Maximum Capacity

Maximum number of physical database connections that this connection pool can contain. Different JDBC Drivers and database servers may limit the number of possible physical connections.

C: Attribute: Statement Cache Size

The algorithm used to maintain the statement cache:

LRU - After the statementCacheSize is met, the Least Recently Used statement is removed when a new statement is used.

Fixed - The first statementCacheSize number of statements is stored and stay fixed in the cache. No new statements are cached unless the cache is manually cleared.

E: If the queue appears starved but adding execute threads does not improve performance,

there may be resource contention. Because CPU utilization is low, the threads are probably

spending much of their time waiting for some resource, quite often a database connection.

Use the JDBC monitoring facilities in the console to check for high levels of waiters or long

wait times. Adding connections to the JDBC connection pool may be all that is required to

fix the problem.

Note:

* If you had a JDBC connection pool where the Initial Capacity and Maximum Capacity attributes were different, you might want to create a gauge monitor to monitor the maximum and minimum number of connections.

By setting the Threshold Low value to be one less than the Initial Capacity, your gauge monitor trapcould monitor the ActiveConnectionsCurrentCount attribute of the JDBCDataSourceRuntime MBean and alert you whenever the number of active connections are less than the Initial Capacity (which might indicate database connectivity problems).

The major components of the WebLogic JMS Server architecture, as illustrated in the figure below.

* (A) JMS servers that can host a defined set of modules and any associated persistent storage that reside on a WebLogic Server instance.

* (B) JMS modules contains configuration resources (such as queues, topics, and connections factories) and are defined by XML documents that conform to the weblogic-jmsmd.xsd schema.

* Client JMS applications that either produce messages to destinations or consume messages from destinations.

* JNDI (Java Naming and Directory Interface), which provides a resource lookup facility. JMS resources such as connection factories and destinations are configured with a JNDI name. The runtime implementations of these resources are then bound into JNDI using the given names.

* (E) WebLogic persistent storage (file store or JDBC-accessible) for storing persistent message data.

The following figure illustrates the WebLogic JMS architecture.

JCA Adapter

This product is a wrapper to the WebLogic Tuxedo Connector (WTC) found as part of the WebLogic Server (WLS) product. WTC can only be used on WebLogic, but the JCA adapter allows deploying WTC capabilities on other Java Application Servers that support the Java EE JCA specification.

Note:

* Tuxedo (Transactions for Unix, Extended for Distributed Operations) is a middleware platform used to manage distributed transaction processing in distributed computing environments. Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages. Developed by AT&T in the 1980s, it became a software product of Oracle Corporation in 2008.
