Kernel Messages: HistoryLocate this document in the navigation structure


The Messages user menu of the DBA Cockpit contains a display of the log files that were backed up during a database crash, as well as the kernel message history. Normally, at least the kernel log knldiag, the database trace log knltrace, and the memory dump rtedump are backed up if the database crashes. These files are in a subdirectory of the directory diaghistory, where they can be used for diagnoses.


Open the DBA Cockpit (transaction DBACOCKPIT) and choose Start of the navigation path Diagnosis End of the navigation path.Start of the navigation path Messages Next navigation step Kernel Messages: Historie End of the navigation path.


For SAP NetWeaver 7.1, you can access the kernel messages through the History user menu.


The existing subdirectories of the diaghistory directory are displayed, sorted according to the time your backup was performed. The available kernel message history (KnlMsg_<timestamp> files) is displayed. You can open and analyze any of the log files.
