OBIEE 11g log files path

In this post, we are going to see where the log files in OBIEE 11g reside.
In OBIEE 10g, we can check the different log files in the installation directory. In OBIEE 11g, we have got Enterprise Manager Console, where we can check log files but we can still see these files in OBIEE install directory.

• Enterprise Manager Console

Log on to EM Console (http://localhost:7001/em) . Once you logged on, in the left pane navigate to Farm_bifoundation_domain –> Business Intelligence–>coreapplications–>Diagnostics–>Log Messages
Here you can see the Most Recent Errors and Most Recent Warnings. After warning messages,  you can also see all the log files grouped by categories using Log Viewer.
Available files:
• Presentation Services Log
• Server Log
• Scheduler Log
• JavaHost Log
• Cluster Controller Log
• Action Services Log
• Security Services Log
• Administrator Services Log

• Manually open log files from your install directory

Use of Log Viewer: You can search for and view the log entries for Oracle Business Intelligence components using Fusion Middleware Control Log Viewer. The log files can be searched for log messages, and you can apply filters that can, for example, target a certain date range, user, user transaction, or level of message (error, warning, notification, and so on). You can also view log files in their entirety from the Fusion Middleware Control Log Viewer
