.SH DESCRIPTION
The \fBovsdb\-tool\fR program is a command-line tool for managing Open
vSwitch database (OVSDB) files. It does not interact directly with
running Open vSwitch database servers (instead, use
\fBovsdb\-client\fR).
.
.SS "Basic Commands"
.IP "\fBcreate\fI db schema\fR"
Reads an OVSDB schema from the file named \fIschema\fR and creates a
new OVSDB database file named \fIdb\fR using that schema. The new
database is initially empty. This command will not overwrite an
existing \fIdb\fR.
.IP
\fIschema\fR must contain an OVSDB schema in JSON format. Refer to
the OVSDB specification for details.
.
.IP "\fBcompact\fI db \fR[\fItarget\fR]"
Reads \fIdb\fR and writes a compacted version. If \fItarget\fR is
specified, the compacted version is written as a new file named
\fItarget\fR, which must not already exist. If \fItarget\fR is
omitted, then the compacted version of the database replaces \fIdb\fR
in-place.
.
.IP "\fBconvert\fI db schema \fR[\fItarget\fR]"
Reads \fIdb\fR, translating it into to the schema specified in
\fIschema\fR, and writes out the new interpretation. If \fItarget\fR
is specified, the translated version is written as a new file named
\fItarget\fR, which must not already exist. If \fItarget\fR is
omitted, then the translated version of the database replaces \fIdb\fR
in-place.
.IP
This command can do simple ``upgrades'' and ``downgrades'' on a
database's schema. The data in \fIdb\fR must be valid when
interpreted under \fIschema\fR, with only one exception: data in
\fIdb\fR for tables and columns that do not exist in \fIschema\fR are
ignored. Columns that exist in \fIschema\fR but not in \fIdb\fR are
set to their default values. All of \fIschema\fR's constraints apply
in full.
.
.IP "\fBneeds\-conversion\fI db schema\fR"
Reads the schema embedded in \fIdb\fR and the standalone schema in
\fIschema\fR and compares them. If the schemas are the same, prints
\fBno\fR on stdout; if they differ, print \fByes\fR.
.
.IP "\fBdb\-version\fI db\fR"
.IQ "\fBschema\-version\fI schema\fR"
Prints the version number in the schema embedded within the database
\fIdb\fR or in the standalone schema \fIschema\fR on stdout. A schema
version number has the form \fIx\fB.\fIy\fB.\fIz\fR. See
\fBovs\-vswitchd.conf.db\fR(5) for details.
.IP
Schema version numbers and Open vSwitch version numbers are
independent.
.IP
If \fIschema\fR or \fIdb\fR was created before schema versioning was
introduced, then it will not have a version number and this command
will print a blank line.
.
.IP "\fBdb\-cksum\fI db\fR"
.IQ "\fBschema\-cksum\fI schema\fR"
Prints the checksum in the schema embedded within the database
\fIdb\fR or of the standalone schema \fIschema\fR on stdout.
.IP
If \fIschema\fR or \fIdb\fR was created before schema checksums were
introduced, then it will not have a checksum and this command
will print a blank line.
.
.IP "\fBquery\fI db transaction\fR"
Opens \fIdb\fR, executes \fItransaction\fR on it, and prints the
results. The \fItransaction\fR must be a JSON array in the format of
the \fBparams\fR array for the JSON-RPC \fBtransact\fR method, as
described in the OVSDB specification.
.IP
The \fIdb\fR is opened for read-only access, so this command may
safely run concurrently with other database activity, including
\fBovsdb\-server\fR and other database writers. The \fItransaction\fR
may specify database modifications, but these will have no effect on
\fIdb\fR.
.
.IP "\fBtransact\fI db transaction\fR"
Opens \fIdb\fR, executes \fItransaction\fR on it, prints the results,
and commits any changes to \fIdb\fR. The \fItransaction\fR must be a
JSON array in the format of the \fBparams\fR array for the JSON-RPC
\fBtransact\fR method, as described in the OVSDB specification.
.IP
The \fIdb\fR is opened and locked for read/write access, so this
command will fail if the database is opened for writing by any other
process, including \fBovsdb\-server\fR(1). Use \fBovsdb\-client\fR(1),
instead, to write to a database that is served by
\fBovsdb\-server\fR(1).
.
.IP "\fBshow\-log\fI db\fR"
Prints a summary of the records in \fIdb\fR's log, including the time
and date at which each database change occurred and any associated
comment. This may be useful for debugging.
.IP
To increase the verbosity of output, add \fB\-m\fR (or \fB\-\-more\fR)
one or more times to the command line. With one \fB\-m\fR,
\fBshow\-log\fR prints a summary of the records added, deleted, or
modified by each transaction. With two \fB\-m\fRs, \fBshow\-log\fR
also prints the values of the columns modified by each change to a
record.
.
.SH OPTIONS
.SS "Logging Options"
.so lib/vlog.man

.SH "FILES"
The default \fIdb\fR is \fB@DBDIR@/conf.db\fR. The
default \fIschema\fR is \fB@pkgdatadir@/vswitch.ovsschema\fR. The
\fBhelp\fR command also displays these defaults.
