The database is missing some indexes. Due to the fact that adding indexes on big tables could take some time they were not added automatically. By running “occ db:add-missing-indices” those missing indexes could be added manually while the instance keeps running. Once the indexes are added queries to those tables are usually much faster.

Missing index "owner_index" in table "share".
Missing index "initiator_index" in table "share".

Some columns in the database are missing a conversion to big int. Due to the fact that changing column types on big tables could take some time they were not changed automatically. By running ‘occ db:convert-filecache-bigint’ those pending changes could be applied manually. This operation needs to be made while the instance is offline. For further details read the documentation page about this.

  • filecache.mtime
  • filecache.storage_mtime

This instance is missing some recommended PHP modules. For improved performance and better compatibility it is highly recommended to install them.
