Oracle soa 11g log files

For lists of loggers, see Oracle Service Bus Loggers. Service Bus includes a variety of loggers to handle messages for various modules. These loggers are all located in the oracle. You cannot configure the oracle. Service Bus provides debug loggers in the oracle. A View list for selecting the type of loggers for which to view information. Choose from runtime or persistent state loggers. A table that displays the logger name, the Oracle Diagnostic Logging ODL level for setting the amount and type of information to write to a log file, the log file, and the log level state.

The Log Files tab displays the log handlers, the log file paths and names, the format of the log messages, the rotation policies used, and other parameters based on the log file configuration class. The Log File page appears.

Changes you make here are not specific to Service Bus. WLST provides commands for updating the logging configuration for a single server. Although debugging should be disabled during normal Service Bus operation, you may find it helpful to specify debug logging for specific modules while you are developing and experimenting with your solution. For example, you may want to turn on the alert debugging flag when you are developing alerts and want to investigate how the alert engine works.

The change takes effect immediately and does not require the server to be restarted. For information about available loggers, see Loggers.

If you monitor log files or services using third-party tools that expect to find "BEA" in log messages and SOAP faults, those tools may no longer work as expected.

To continue using the "BEA" prefix in Service Bus messages, set the following system property at runtime:. When you are working with Service Bus offline instead of running in an application server, the logging environment is not automatically configured. To configure offline logging, you need to configure the logging.

You can download log files to your local client and view them using another tool; for example, a text editor or another file viewing utility. To view Service Bus log messages:. For more information about the search criteria on this page, see the online help for the page and " Searching Log Files " in Administering Oracle Fusion Middleware. To group messages by message attributes, such as ECID, message type, or target, select the combination of attributes in the Show field.

To export the messages to a file, click Export Message to File and then select the type of file text, XML, or comma-separated. To change the refresh rate for messages, click in the refresh field and select a second refresh rate, 1-minute refresh rate, or manual refresh.

The View menu above the log file entries lets you select which columns to display and in what order. You can also define how to sort the displayed messages. Click the View menu, point to Columns , and then select a column name to display. Click the View menu, point to Columns , and then deselect a column name to remove it. Click the View menu, point to Sort , and then select Advanced. Repeat the above step for any additional columns to sort by, and then click OK.

Select a column to reorder and then move it up or down in the list using the arrow buttons on the right. Repeat the above step for any additional columns to move, and then click OK. WLST provides commands for searching and viewing log messages. These list the standard loggers provided with Service Bus and list the debug loggers along with their correspondence to the debug loggers from the previous version.

Post a Comment. Oracle 11gR2 is a major release upgrade from 10gR2 and 11gR1 both. All rights reserved. Many of the adrci commands are very similar to the standard Unix vi commands. By default, the log files are rotated when they reach 10 MB. The maximum size of all log files for a particular component is MB. The maximum size of the log file. You specify that a new log file be created when a specific time or frequency is reached. For Start Time, enter the date when you want the rotation to start.

For example, enter SEP For Frequency, you can select Minutes and enter the number of minutes, or you can select Hourly, Daily, or Weekly. For Retention Period, you can specify how long the log files are kept. You can select Minutes and enter the number of minutes, or you can specify Day, Week , Month, or Year. Specifying a shorter period means that you use less disk space, but are not able to retrieve older information.

You can specify size-based rotation or time-based rotation. For example, to specify that the log files rotate daily and that they are retained for a week, use the following command:.

To specify that the size of a log file does not exceed 5MB and rotates when it reaches that size, use the following command:. You can configure the amount and type of information written to log files by specifying the message type and level.

For each message type, possible values for message level are from 1 highest severity through 32 lowest severity. Some components support only some of the levels for each message type. Generally, you need to specify only the type; you do not need to specify the level. When you specify the type, Oracle Fusion Middleware returns all messages of that type, as well as the messages that have a higher severity. Table shows the message types and the most common levels for each type. Table Diagnostic Message Types and Level.

A serious problem that may be caused by a bug in the product and that should be reported to Oracle Support. A serious problem that requires immediate attention from the administrator and is not caused by a bug in the product. An example is if Oracle Fusion Middleware cannot process a log file, but you can correct the problem by fixing the permissions on the document.

A major lifecycle event such as the activation or deactivation of a primary sub-component or feature. Trace or debug information for events that are meaningful to administrators, such as public API entry or exit points. Detailed trace or debug information that can help Oracle Support diagnose problems with a particular subsystem.

Very detailed trace or debug information that can help Oracle Support diagnose problems with a particular subsystem. For other types and levels, note the following:. You can enable this level occasionally on a production environment to debug problems. This level should not be enabled on a production environment, except on special situations to debug problems. This level should not be enabled in a production environment.

It is intended to be used to debug the product on a test or development environment. For Log Level, select the logging level. Run-time loggers are loggers that are currently active. Persistent loggers are loggers that are saved in a configuration file and log levels of these loggers are persistent across component restarts.

A run-time logger can also be a persistent logger, but not all run-time loggers are persistent loggers. In the table, to specify the same level for all loggers, select the logging level for Root Logger for run-time loggers or oracle for persistent loggers. Then, for the child loggers, specify Inherit from Parent. For most situations, that is sufficient.

However, if you need to specify the level for a particular logger, expand Root Logger or oracle, then, for the logger that you want to modify, select the logging level.

For example, for the logger oracle. To get the current message level, you use the getLogLevel command. You must be connected to WebLogic Server before you use the configuration commands. You can view the log level for a logger for an Oracle WebLogic Server. You can set the log level for a particular logger.

You can also filter logger names using the pattern parameter and a regular expression. By default, information is written to log files in ODL text format.

ODL-Text is the default. The language and data formats used in the log files are determined by the default locale of the server Java Virtual Machine JVM. The character encoding of log files is determined by the server JVM's default character encoding or an optional configuration setting. You should choose an encoding that supports all languages used by the users, or the log file may be corrupted.

By default, log is in the server JVM's default character encoding. If you change the encoding, delete or rename old log files to prevent them from being damaged by the new logs appended in a different encoding. On Windows, you can enable UTF-8 logging as described in the following topics. You can specify the log file locale using WLST commands or by editing a file, as described in the following topics:.

You can use the encoding parameter to specify the character set encoding. To specify the log file encoding in the logging. You can specify the encoding property to specify the character set encoding. Oracle Fusion Middleware components provide message correlation information for diagnostic messages.

Message correlation information helps those viewing diagnostic messages to determine relationships between messages across components. An ECID is a globally unique identifier associated with the execution of a particular request. An ECID is generated when the request is first processed.

A RID distinguishes the work done in one thread on one process, from work done by any other threads on this and other processes on behalf of the same request.

By searching for related messages using the message correlation information, multiple messages can be examined and the component that first generates a problem can be identified this technique is called first-fault component isolation. Message correlation data can help establish a clear path for a diagnostic message across components, within which errors and related behavior can be understood.

The RID is one or more numbers separated by a colon :. The first RID created for a request is 0. Each time work is passed from a thread that has an ECID associated with it to another thread or process, a new RID is generated that encodes the relationship to its creator.

A different and much more flexible approach is service discovery. In this approach, the identity of the target service is not known at programming time, but is discovered at run time. The user program finds target services that meet its requirements, and chooses one of them.

This is called asset wrapping. When an enterprise adopts an SOA, asset wrapping is typically applied to existing application software packages. This provides a significant benefit:. This technique is called virtualization. Virtualization can be used to enable programs that were written to use one asset to be executed with a different asset. But in the context of SOA it is more commonly used to create virtual assets that are functionally similar to the underlying assets. This can deliver two benefits:.

Model-driven implementation refers to the automatic realization of a system or application from an abstract model. Where the model starts at a high level of architectural abstraction, it is usually referred to as Model-Driven Architecture MDA. SOA lends itself particularly well to model-driven implementation, because it is based on a high-level software module concept the service for which there are good definition and interface standards.

In SOA, model-driven implementation can be applied to service compositions as well as to software services. TekSlate is the best online training provider in delivering world-class IT skills to individuals and corporates from all parts of the globe.
