Chapter 5. Configuration

The default location of DDS's configuration file is ~/.DDS/DDS.cfg. If missing, the configuration file will be automatically created once the DDS environment script is sourced.

DDS's configuration engine looks for the configuration file in the following order:

$HOME/.DDS/DDS.cfg
$DDS_LOCATION/etc/DDS.cfg
$DDS_LOCATION/DDS.cfg

Table 5.1. DDS configuration variables

Key	Description
server.work_dir	DDS commander will use this directory to create session files.
server.sandbox_dir	Some RMS, like LSF and slurm for example, require a shared files system to submit jobs. A shared folder (shared between the submit host and worker nodes). DDS will place RMS job script in this folder and will also use this folder as a sandbox for DDS workers.
server.log_dir	DDS commander will use this directory for logs.
server.log_severity_level	A global log severity level. Used by all DDS modules. Log severity can be one of the following values: p_l - protocol low level events and higher, p_m - protocol middle level events and higher, p_h - protocol high level events and higher, dbg - general debug events and higher, inf - info events and higher, wrn - warning events and higher, err - error events and higher, fat - fatal errors.
server.log_rotation_size	Log rotation size in MB. Once a log file reaches this number DDS will automatically create another log file.
server.log_has_console_output	0 or 1. If 1, then DDS console outputs will be also saved into the log.
server.commander_port_range_min and server.commander_port_range_max	A port range used by the commander.
server.idle_time	An idle time in seconds. DDS Commander and Agents respect this number and will automatically shutdown if inactive for this amount of seconds.
agent.work_dir	Use this key if you want to relocate working directories of DDS agents. By default they will use the directory specified by "server.sandbox_dir".
