The activity log does not analyze any other log files, such as default_stderr.log or tracefile. To analyze these records, right click on a record in the tree on the left (click on the UnitOfWorkView at the top to get them all), and select Analyze. Any records with a green check mark next to them match a record in the symptom database. When you select a check-marked record, you will see an explanation of the problem in the lower right-hand pane.
Updating the symptom database
The database of known problems and resolutions used when you click the Analyze menu item is periodically enhanced as new problems come to light and new versions of the product are introduced. To ensure that you have the latest version of the database, use the File > Update Database > WebSphere Application Server Symptom Database menu item from within the log analyzer tool at least once a month. Users who have just installed the product and have never run the update should do so immediately, since updates may have occurred since the version was first released.
The knowledge base used for analysis is built gradually from problems reported by users. For a recently released version of the product, you might not find any analysis hits. However, the Log Analyzer tool still provides a way to see all error messages and warnings from all components in a convenient, user-friendly way.
