Maintenance Tasks
Additional commands are provided for common maintenance tasks like upgrading the application, migrating the database and pruning expired resumption tokens.
Pruning Expired Tokens
When serving large amounts of records the OAI-PMH2 Data Provider splits the result set in batches issuing resumption tokens for flow control. Those are kept in the database, but expire after a certain time. It is therefore advisable to regularly remove expired tokens.
# Delete expired tokens
bin/cli oai:prune:tokensInstead of running this command manually over and over again it is recommended to set up a maintenance cronjob.
Performing Upgrades
Upgrading the OAI-PMH2 Data Provider is as easy as running a single command.
# Upgrade to the latest stable release
bin/cli app:upgradeInitializing a new database or migrating an existing database after a manual upgrade can be performed by running the
following command. (app:install:db
and app:upgrade:db
are aliases of the same command.)
# Migrate (or initialize) the database
bin/cli app:upgrade:dbBe aware that migrations can potentially lead to data loss. Always keep a backup when performing upgrades and migrations!
