The working directory of a database instance is the directory where the database system saves configuration and log files. If you enter a relative path when working with a database instance, the database system will always interpret this path as being relative to the run directory.
If you create a new database instance, you configure the <independent_data_path>, thereby implicitly configuring the working directory path. The default value for the working directory path is <independent_data_path>\wrk\<database_name>. The database system stores the working directory path in the general database parameter RUNDIRECTORY.
Run directory of the database instance DEMODB
Microsoft Windows:
C:\Documents and Settings\All Users\Application Data\sdb\data\wrk\DEMODB
UNIX/Linux:
/var/opt/sdb/data/wrk/DEMODB
After a system breakdown and a restart, the database system transfers the old log files to the <diag_history_path> directory (default value: <independent_data_path>\wrk\<database_name>\DIAGHISTORY).
