Maintenance #

--initdb

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

--rebuilddb

Rebuild the database from the installed package headers. Discards any unreadable (corrupt) headers and compacts the database in case it has grown large over time.

Can also be used to convert between different rpmdb formats.

--parkdb

Park the database. Prepares and optimizes the database for inclusion on read-only media, such as immutable OS images.

Write operations, such as RPM transactions, will unpark the database and continue normally, leaving the database unparked when finished. Thus, to unpark manually, use --rebuilddb.

Depending on the backend used, this operation may include the removal of auxiliary, backend-specific files from disk, such as the write-ahead log or shared memory index, and thus facilitate bit-for-bit reproducible OS images.

Diagnostics #

--verifydb

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

Migration #

--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.
