These indices are built initially when Fedora is started for the first time on a non-empty OCFL. As content is added, updated and deleted, the indices are updated accordingly. You may at some point wish to rebuild these indices from scratch for a variety of reasons. For example, it is likely that a future change (in subsequent releases) to the index structures could require a rebuild. In that case you can accomplish this task by taking simply restarting Fedora with the following steps.
- Stop Fedora
- Remove the index data in your database (see instructions below for the database you are using)
- Start Fedora
flag:
| Code Block |
|---|
-Dfcrepo.rebuild.on.start=true |
NOTE: Depending on the size of your repository, the type of database, and/or the capacity of your database server, the rebuild can take anywhere from a few seconds to several hours (i.e if you have many millions of objects).
Removing Index Data
Step 2 above will be accomplished differently depending on which underlying database you're using and how your system is configured.
Embedded (H2) Database users
NOTE: The H2 database should not be used in a production installation.
To remove the default (ie H2 database) simply delete the following files from your <fedora_home>/data directory if they exist:
- fcrepo-h2.lock.db
- fcrepo-h2.mv.db
Postgres, MariaDB, and MySQL Users
If you are using one of the three available SQL databases, you'll need to take one of the following actions:
...
Drop or truncate the fcrepo database tables if it is inconvenient to drop the entire database. Below is a list of the affected tables.
