RPMDB(8) System Manager's Manual RPMDB(8)
rpmdb - RPM Database Tool
rpmdb [options] {--initdb|--rebuilddb}
rpmdb [options] {--verifydb}
rpmdb [options] {--exportdb|--importdb}
The rpmdb is used for rpm database maintenance 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.
See rpm-common(8) for the options common to all rpm executables.
There are several configurables affecting the rpmdb operations,
but in particular the following (see rpm-config(5) for details):
• %_dbpath
• %_db_backend
On success, 0 is returned, a nonzero failure code otherwise.
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.
See rpm-common(8) for the options common to all operations.
popt(3), rpm(8), rpm-common(8)
rpmdb --help - as rpm(8) supports customizing the options via popt
aliases it's impossible to guarantee that what's described in the
manual matches what's available.
