Database Messages

KnlMsg

Run directory of the database (see Run Directory).

KNLMSG

Current kernel log file of the database, containing all kernel messages (error messages, warnings, and information)

This file is written in a pseudo-XML format.

The first part of the file contains messages of the database start into the operational state ADMIN: information about the software version, important paths and the current values of the database parameters. These messages are not be overwritten until the next database start, when the old version of the kernel log file is copied to the Database Messages (Old) file.

The second part of the file contains the messages that the database writes during operation. These messages will be overwritten cyclically. If the database crashes, a stack back trace is written.

Database Errors

KnlMsgArchive

Run directory of the database

KNLMSGARC

Error messages and start messages of the kernel since installation

This file is written in a pseudo-XML format.

This file is not overwritten cyclically. If you are analyzing database problems and the Database Messages and Database Messages (Old) files do not contain the relevant information anymore, check the Database Errors file.
