The sgedbwriter script starts the dbwriter program. The script is located in sge_root/dbwriter/bin/sgedbwriter. The sgedbwriter script reads the dbwriter configuration file, dbwriter.conf. This configuration file is located in sge_root/cell/common/dbwriter.conf. This configuration file sets the debug level of dbwriter. For example:
# # Debug level # Valid values: WARNING, INFO, CONFIG, FINE, FINER, FINEST, ALL # DBWRITER_DEBUG=INFO
You can use the –debug option of the dbwriter command to change the number of messages that the dbwriter produces. In general, you should use the default debug level, which is info. If you use a more verbose debug level, you substantially increase the amount of data output by dbwriter.
You can specify the following debug levels:
Displays only severe errors and warnings.
Adds a number of informational messages. info is the default debug level.
Gives additional information that is related to dbwriter configuration, for example, about the processing of rules.
Produces more information. If you choose this debug level, all SQL statements run by dbwriter are output.
Displays information for all levels. For debugging.
