Use

The database system, database tools and interfaces write information and error messages in log files. Most log files are text files that you can read with a text editor.

Exceptions:

·        Binary log files

·        Log files that are only generated by the database system when requested by a user

To display the contents of such log files, use the Database Manager database tool, or the CCMS in SAP systems. You need the file ID of the log file.

Caution

Note that file IDs are case-sensitive.

See:

·        Database Manager GUI, Reading Database Files

·        Database Manager CLI, Opening a Database File

·        Database Administration in CCMS: MaxDB, Structure linkLogs and Structure linkMessages

·        Database Administration in CCMS: SAP liveCache Technology, Structure linkLogs and Structure linkMessages

For more information about the most important database directories, see Directories. For a list of the variables that are used for directory names in the documentation, see Variables and Examples.
