RPM Database Tool

Synopsis

rpmdb [options] {--initdb|--rebuilddb}

rpmdb [options] {--verifydb}

rpmdb [options] {--exportdb|--importdb}

Description

The rpmdb is used for rpm database maintenance operations.

Operations

--initdb

Create a new database if one doesn't already exist. An existing database is not overwritten.

--rebuilddb

Rebuild database from the installed package headers. Rebuilding discards any unreadable (corrupt) headers from the database, but also compacts the database in case it has grown large over time.

Can also be used to convert between different rpmdb formats.

--verifydb

Perform a low-level integrity check on the database. Rarely useful, for system health rpm --verify -a is a far more meaningful operation.

--exportdb

Export the database in header-list format, suitable for transporting to another host or database type. The data is output to standard output.

--importdb

Imports a database from a header-list format as created by --exportdb. The data is read from standard input.

Options

See rpm-common(8) for the options common to all rpm executables.

Configuration

There are several configurables affecting the rpmdb operations, but in particular the following (see rpm-config(5) for details):

%_dbpath
%_db_backend

Exit Status

On success, 0 is returned, a nonzero failure code otherwise.

Examples

rpmdb --initdb --dbpath /tmp/testdb: Initialize a new database in /tmp/testdb directory.
rpmdb --rebuilddb: Rebuild the system rpmdb.
rpmdb --verifydb --root /mnt: Verify the system database of a system image mounted at /mnt.
rpmdb --exportdb > /tmp/headers: Export the system database to /tmp/headers file.
rpmdb --importdb --define "_db_backend ndb" --dbpath /tmp/newdb < /tmp/headers: Import contents of /tmp/headers header list to a (new) ndb-format database in /tmp/newdb.
