The dbvoldump utility may be used to display volume file information.
usage: dbvoldump [options]
options:
-c cfg - configuration file name
-S - output summary about total DATA space
-d flags - debug flags
The options below are intended for use by product support only:
-vp - output volume parameters
-vn - output node directory
-f file - specify single volume file name
The options are:
- -help
- The -help option displays a brief help text.
- -c cfg
- The -c option specifies the eloqdb server configuration file name. If not specified,
the default configuration file name depends on OS platform and Eloquence version.
- -S
- The -S option displays additional summary info about total DATA volume space.
- -d flags
- The -d option specifies debug flags and is normally not used.
- -vp
- The -vp option displays internal volume parameters (used by product support).
- -vn
- The -vn option displays internal node directory info (used by product support).
- -f file
- The -f option specifies a single volume file name for options -vp or -vn.
- Periodically monitoring dbvoldump -S as well as file system free space helps to
prevent database server crashes caused by running out of space inside the volume
files or during an automatic volume expansion.
- The dbvoldump -S results are based on the VolumeFileSizeLimit in the eloqdb server
config file; they may be incorrect when the limit of the running server has been
changed with the "dbctl volume limit" command.
The following example displays volume information.
The option -S shows summary information on available disk space
in the data volumes.
$ dbvoldump -c eloqdb.cfg -S
