Oracle oem where error log file

This is a trace file for Console application. The Management Service saves information to this log file for background modules such as the loader, job system, event system, notification system, and so on. This trace file provides additional logging for the background modules such as the loader, job system, event system, notification system, and so on when DEBUG or INFO level logging is enabled for these modules.

This file can provide Support personnel with even more information about actions these modules were performing when a particular problem occurred.

OMS log and trace files are stored in the following location:. OMS log and trace files increases in size over time as information is written to the files. However, the files are designed to reach a maximum size.

When the files reach the predefined maximum size, the OMS renames or rolls the logging information to a new file name and starts a new log or trace file. This process keeps the log and trace files from growing too large.

As a result, you will often see multiple log and trace files in the OMS log directory. To control the maximum size of the OMS log and OMS trace files, as well as the number of rollover files, run the following command, and specify details as described in Table :. The size of the log is specified in units of bytes.

This optional property indicates how many times OMS will rollover the log file to a new file name before deleting logging data. Note: Because the log file does not contain as much data as the trace file, it is usually not necessary to create more than one rollover file. When the OMS trace file reaches this size, then OMS copies the logging data to a new rollover file and creates a new emoms.

This property indicates how many times the OMS will rollover the trace file to a new file name before deleting tracing data. By default, the OMS will save all critical and warning messages to the emoms. However, you can adjust the amount of logging information that the OMS generates. To change the logging module, contact Oracle Support.

Different components of the Oracle WebLogic Server generate their own log files. These files contain important information that can be used later by support personnel to troubleshoot problems. This log can be restricted, rotated by size, time, and other conditions from the WebLogic Console.

The default settings are:. The messages written to sysout and syserr will be available in the. They cannot be rotated by size or time.

They are rotated only when the server starts. They are located at:. By default, the Enterprise Manager Cloud Control configures OHS logs to rollover periodically to a new file, so that each file does not grow too large in size.

You must also ensure that you delete the old rollover files periodically to free up the disk space. You can use an operating system scheduler, like cron on UNIX, to periodically delete the rollover files. Skip Headers. This reflects the local time zone.

The type and amount of information written to trace log files is determined by the message type and log level specified. Select from one of the values listed in Table , ordered from highest to lowest severity.

The lower the severity level, the more information is written to the log file. Table Trace Log Levels of Severity. A serious problem, such as one from which you cannot recover.

The problem may be caused by a bug in the product and 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. A potential problem, such as invalid parameter values or a specified file that does not exist, that should be reviewed by the administrator. A major lifecycle event such as the activation or deactivation of a primary subcomponent or feature.

Trace or debug information for events that are meaningful to end-users of the product, such as public API entry or exit points.

This file is used for troubleshooting the OMS restart problem. It provides information such as the exact time when the OMS is restarted and which module has caused the crash. This directory stores all log and trace files related to OMS 12c. You can choose to change this, if you want, in the installer. However, you can change it for only advanced installation and not for simple installation.

OMS log and trace files increases in size over time as information is written to the files. However, the files are designed to reach a maximum size. When the files reach the predefined maximum size, the OMS renames or rolls the logging information to a new file name and starts a new log or trace file.

This process keeps the log and trace files from growing too large. As a result, you will often see multiple log and trace files in the OMS log directory.

To control the maximum size of the OMS log and OMS trace files, as well as the number of rollover files, run the following command, and specify details as described in Table :. The above command will set the property for all OMSes. The OMS name has to be similar to example. The size of the log is specified in units of bytes.

This optional property indicates how many times OMS will rollover the log file to a new file name before deleting logging data. Note: Because the log file does not contain as much data as the trace file, it is usually not necessary to create more than one rollover file.

Table Component Log File Location. This log can be restricted, rotated by size, time, and other conditions from the WebLogic Console. The default settings are:. The messages written to sysout and syserr will be available in the. They cannot be rotated by size or time. They are rotated only when the server starts. They are located at:. You must also ensure that you delete the old rollover files periodically to free up the disk space.

You can use an operating system scheduler, like cron on UNIX, to periodically delete the rollover files. You can set up Cloud Control to receive alert notifications in the context of targets when patterns are found. This allows you to be more proactive and learn of problems as an administrator before end users discover them.

Log Viewer enables administrators to view, search, and download middleware-related log files regardless of where the files reside on disk. Complex search criteria can be specified and saved for future reference in order to help administrators quickly diagnose performance problems across multiple middleware components spanning multiple Fusion Middleware Farms and WebLogic Domains. For log viewer features to fully function in this environment, you must apply additional configuration changes.

You must take the rootca of the custom certificate from the Admin Server target for the domain against which you want to view log messages and import it into the trust store of the OMS. When accessing Log Viewer, default search criteria is specified for the selected target type. The administrator can then refine the search criteria based on diagnostic requirements for the particular Fusion Middleware Farm. By using the Add Fields button, you can refine the search criteria to include:.

The administrator modifies the search as needed and clicks the Save Search button on the Log Viewer. The search criteria specified, including the targets against which the search was performed, is then saved to the Management Repository for the currently logged in administrator.

You can click on the Saved Searches button to retrieve and apply a previously stored Search Criteria. You can click on the Manage Saved Searches and bring up a pop-up to edit or delete the previously Saved Search Criteria.

You can use Log File Monitoring to monitor WebLogic Server and Application Deployment log files for specific patterns and thereby reduce troubleshooting time. You can set up Cloud Control to receive alert notifications in context of targets when patterns are found. In addition, you can specify a perl pattern to be ignored for the log file. Periodic scanning, which occurs by default every 60 minutes, is performed against any new content added since the last scan.

Lines matching the ignore pattern are ignored first, then lines matching specified match patterns result in one record being uploaded to the repository for each pattern. You can set a threshold against the number of lines matching the given pattern.

File rotation will be handled within the given file. You can also use the monitoring templates functionality, which allows an administrator to configure a metric once in a template and then apply the template to several WebLogic Server or Application Deployment targets at once, rather than having to configure each WebLogic Server log file monitoring metric individually.

If you are currently using log file monitoring via the Host target type, you should configure log file monitoring via the Fusion Middleware related target type instead so you can see alerts in context of a Fusion Middleware target. Log File Monitoring requires a local Management Agent monitoring target. In other words, the host on which the log files you want to monitor reside must have an agent installed and running. The OS user who installed the agent must have read access to directories where the monitored log files reside.

Log file monitoring is disabled by default. You must enable it in order to use this feature. Once you enable and configure Log File Monitoring, the default collection schedule is set for every 60 minutes. Click Add to add new object s in order to specify settings for the log files to be monitored. Add objects to the Monitored Objects table. The Reorder button specifies which log file to scan first.

However, this behavior has been updated wherein only "" an empty string is the prescribed method not to ignore any lines. The Match Pattern in Perl value specifies the pattern that should be monitored in the log file. Perl expressions are supported in this field, and case is ignored. The Ignore Pattern in Perl value specifies the pattern that should be ignored in the log file. The Warning Threshold and Critical Threshold values should be set to a number such that if the pattern occurs in the log file the specified number of times within the collection schedule, then an alert will be triggered.

If the number of occurrences is specified in the advanced settings, then this factors into when alert is raised. For example, if you set the critical threshold to 1 if pattern found more than 1 time in log file, it is critical alert and the number of occurrences to 2, then a critical alert is raised only when the pattern is found more than once in the log file within 2 consecutive collections.

Log file locations must be the same across targets to which the template is applied. You can apply the template to multiple WebLogic servers or Application Deployment targets at once rather than setting monitoring settings individually on a per-target basis.

If after configuring the Log File Monitoring metric the log file contains the specified patterns but the alerts are not generated in the OMS, you should do the following:. Providing an asterisk in the ignore pattern field will also ignore all the lines which include the matched patterns. If an error message displays indicating that logging configuration is missing or invalid for certain targets, you can try the following options. Oracle JRF consists of components not included in the Oracle WebLogic Server installation and that provide common functionality for Oracle business applications and application frameworks.

To view log messages, the target must be Oracle JRF enabled. The value for this property could be true or false. If the value is false, then the domain is not Oracle JRF enabled.

If you are unable to access log messages in the context of a specific managed server, then navigate to the relevant managed server's Monitoring Configuration page. If the value is false, then the managed server is not Oracle JRF enabled. Second, the Enterprise Manager Cloud Control administrator who is trying to access log messages does not have the necessary target privileges to do so.

Talk to your Oracle Enterprise Manager's site administrator or super administrator regarding whether you have this privilege or not. Refer to later questions in this document for additional details on this target privilege and granting the privilege to administrators.

You can configure the host, its credentials, and archive location information for a WebLogic domain and for all targets under the domain. You can either configure everything collectively under the target at the same time, or you can configure the targets individually. The host name you selected now appears in the Host column of the Configure Archive Locations page, and the column also displays this host for all of the child targets.

Double-click a directory name to enter in the host name field, then repeat this process for each sub-directory that you want to in the field. Click OK when you have finished. The directory location you selected now appears in the Archive Location column of the Configure Archive Locations page, and the column also displays this location for all of the child targets. To configure the targets separately, follow the procedure above, except select a particular target rather than the WebLogic domain.
