Again this morning I received a message of my departure I told myself that my database was full. When I looked at this one, it was the oc_filecache table that was full
For example look at the image below. I emptied it barely an hour ago and it is already at 205021
This sounds absolutely absurd to me. The oc_filecache table contains file metadata for every file/folder/share in ownCloud. Without it ownCloud can’t work. Deleting it, destroys ownership, share and a lot of other vital information. Why are you meddling with this? Are you getting a specific error message?
You will have to upgrade your plan to allow for a larger database, or remove data/users/shares from your owncloud installation in order to resolve this issue.
Sorry but I don’t speak English very well. I am translating what you say with google translate and if I understand correctly I have to take a larger database is that it?
What do you mean when you say
remove, data/users/shares from your owncloud installation in order to resolve this issue.
As other users already wrote: the file cache table is the main table which stores all the files and shares metadata. You must never touch this table unless you really know what you are doing.
From my experience, a big amount of filecache entries comes from the trashbin and version apps. When files are deleted or versioned they occupy an entry in the table. To reduce this “overhead” you may provide harder retention policies, see the documentation at Define the trashbin retention obligation and Define the files versions retention obligation
