Property Configurator

http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PropertyConfigurator.html

All option values admit variable substitution. The syntax of variable substitution is similar to that of Unix shells. The string between an opening "${" and closing "}" is interpreted as a key. The value of the substituted variable can be defined as a system property or in the configuration file itself.

appc

The appc compiler generates and compiles the classes needed to deploy EJBs and JSPs to WebLogic Server. It also validates the deployment descriptors for compliance with the current specifications at both the individual module level and the application level. The application-level checks include checks between the application-level deployment descriptors and the individual modules as well as validation checks across the modules.

externally-defined

The externally-defined element lets you explicitly indicate that you want the security roles defined by the role-name element in the weblogic-ejb-jar.xml deployment descriptors to use the mappings specified in the Administration Console. The element gives you the flexibility of not having to specify a specific security role mapping for each security role defined in the deployment descriptors for a particular Web application. Therefore, within the same security realm, deployment descriptors can be used to specify and modify security for some applications while the Administration Console can be used to specify and modify security for others.

If you see this error in logs/DefaultAuditRecorder.log when anonymous access to WLS JNDI tree is disabled

#### Audit Record Begin Nov 30, 2010 1:42:14 PM Severity =FAILURE Event Type = Authorization Audit Event V2 Subject: 0
ONCEjndi type= jndi , application=, path={weblogic}, action=lookup Audit Record End ####


you can disable internal WLS application
Async web service support is not fully configured. The async response web service /AsyncResponseServiceSoap12Https for this server was not fully deployed because the JMS reliability queue was not defined/deployed: weblogic.wsee.DefaultQueue. The server will periodically retry completing the deploy for the service. This message can usually be ignored unless there are async web service applications. To completely disable async web service support, thus avoiding this message, set -Dweblogic.wsee.skip.async.response=true

Connection pool overload on Weblogic server - forcibly release inactive connection

The number of inactive seconds on a reserved connection before WebLogic Server reclaims the connection and releases it back into the connection pool.

You can use the Inactive Connection Timeout feature to reclaim leaked connections - connections that were not explicitly closed by the application. Note that this feature is not intended to be used in place of properly closing connections.

When set to 0, the feature is disabled.

MBean Attribute (Does not apply to application modules) :
JDBCConnectionPoolParamsBean.InactiveConnectionTimeoutSeconds

Configure Java logging file handler

http://download.oracle.com/javase/6/docs/api/java/util/logging/package-summary.html


java.util.logging.config.file defines file used
by LogManager to configure root logger

FileHandler

%g the generation number to distinguish rotated logs

java.util.logging.FileHandler.count specifies how many output files to cycle through (defaults to 1).

http://www.linuxtopia.org/online_books/programming_books/thinking_in_java/TIJ317_021.htm

FileHandlers for non-root logger must be specified using Java.

FileHandler fh = null;

Java Troubleshooting, Profiling, Monitoring and Management Tools

Java VisualVM


jvisualvm

A graphical tool that provides detailed information about the Java technology-based applications (Java applications) while they are running in a Java Virtual Machine. Java VisualVM provides memory and CPU profiling, heap dump analysis, memory leak detection, access to MBeans, and garbage collection.

jconsole A JMX-compliant graphical tool for monitoring a Java virtual machine. It can monitor both local and remote JVMs. It can also monitor and manage an application.

Monitoring Tools

jps JVM Process Status Tool - Lists instrumented HotSpot Java virtual machines on a target system.

jstat JVM Statistics Monitoring Tool - Attaches to an instrumented HotSpot Java virtual machine and collects and logs performance statistics as specified by the command line options.

Troubleshooting Tools

jinfo Configuration Info for Java - Prints configuration information for a given process or core file or a remote debug server.

jhat Heap Dump Browser - Starts a web server on a heap dump file (eg, produced by jmap -dump), allowing the heap to be browsed.

jmap Memory Map for Java - Prints shared object memory maps or heap memory details of a given process or core file or a remote debug server.

jsadebugd Serviceability Agent Debug Daemon for Java - Attaches to a process or core file and acts as a debug server.

jstack Stack Trace for Java - Prints a stack trace of threads for a given process or core file or remote debug server.
