    Daemon (SlurmDBD) configuration information.
    The file location can be modified at system build time using the
    DEFAULT_SLURM_CONF parameter or at execution time by setting the SLURM_CONF
    environment variable.
    .LP
    The contents of the file are case insensitive except for the names of nodes
    and files. Any text following a "#" in the configuration file is treated
    as a comment through the end of that line.
    Changes to the configuration file take effect upon restart of
    SlurmDbd or daemon receipt of the SIGHUP signal unless otherwise noted.
    .LP
    This file should be only on the computer where SlurmDBD executes and
    should only be readable by the user which executes SlurmDBD (e.g. "slurm").
    If the slurmdbd daemon is started as user root and changes to another
    user ID, the configuration file will initially be read as user root, but will
    be read as the other user ID in response to a SIGHUP signal.
    This file should be protected from unauthorized access since it
    contains a database password.
    The overall configuration parameters available include:

    .TP
    \fBArchiveDir\fR
    If ArchiveScript is not set the slurmdbd will generate a file that can be
    read in anytime with sacctmgr load filename.  This directory is where the
    file will be placed after a purge event has happened and archive for that
    element is set to true.  Default is /tmp.  The format for this files name is
    .na
    $ArchiveDir/$ClusterName_$ArchiveObject_archive_$BeginTimeStamp_$endTimeStamp
    .ad
    We limit archive files to 50000 records per file. If more than 50000 records
    exist during that time period, they will be written to a new file.  Subsequent
    archive files during the same time period will have ".<number>" appended
    to the file, for example .2, with the number increasing by one for each file in
    the same time period.

    .TP

    When purging events also archive them.  Boolean, yes to archive event data,

    transaction data, no otherwise.  Default is no.

    .TP
    \fBArchiveUsage\fR
    When purging usage data (Cluster, Association and WCKey) also archive it.
    Boolean, yes to archive transaction data, no otherwise.  Default is no.

    .TP
    \fBAuthInfo\fR
    Additional information to be used for authentication of communications
    with the Slurm control daemon (slurmctld) on each cluster.
    The interpretation of this option is specific to the configured \fBAuthType\fR.

    \fBjwt_key=\fR
    Absolute path to JWT key file. Key must be HS256, and should only be accessible
    by SlurmUser.
    .RE

    .TP
    \fBAuthType\fR
    Define the authentication method for communications between Slurm
    components.
    Acceptable values at present include "auth/none" and "auth/munge".
    The default value is "auth/munge".
    \fBDo not use "auth/none" if you desire any security\fR.
    "auth/munge" indicates that LLNL's MUNGE system is to be used
    (this is the supported authentication mechanism for Slurm;
    see "https://dun.github.io/munge/" for more information).
    SlurmDBD must be terminated prior to changing the value of \fBAuthType\fR
    and later restarted.

    .TP
    \fBCommitDelay\fR
    How many seconds between commits on a connection from a Slurmctld.  This
    speeds up inserts into the database dramatically.  If you are running a very
    high throughput of jobs you should consider setting this.  In testing, 1 second
    improves the slurmdbd performance dramatically and reduces overhead.  There is
    a small probability of data loss though since this creates a window in which
    if the slurmdbd seg faults or exits abnormally for any reason the data not
    committed could be lost.  While this situation should be very rare,
    it does present an extremely small risk, but may be the only way to run in
    extremely heavy environments.  In all honesty, the risk is quite low, but still
    present.

    .TP
    \fBCommunicationParameters\fR
    Comma separated options identifying communication options.
    .RS
    .TP 15

    Disable IPv4 only operation for the slurmdbd. This should also be set in your
    \fBslurm.conf\fR file.
    .TP
    \fBEnableIPv6\fR
    Enable using IPv6 addresses for the slurmdbd. When using both IPv4 and IPv6,
    address family preferences will be based on your /etc/gai.conf file. This
    should also be set in your \fBslurm.conf\fR file.

    This value must be specified.

    .TP
    \fBDbdPort\fR
    The port number that the Slurm Database Daemon (slurmdbd) listens
    to for work. The default value is SLURMDBD_PORT as established at system
    build time. If no value is explicitly specified, it will be set to 6819.
    This value must be equal to the \fBAccountingStoragePort\fR parameter in the
    slurm.conf file.

    .TP
    \fBDebugFlags\fR
    Defines specific subsystems which should provide more detailed event logging.
    Multiple subsystems can be specified with comma separators.
    Most DebugFlags will result in verbose logging for the identified subsystems
    and could impact performance.
