Transactional file locking Shared Hosting

Steps to reproduce

  1. Opening the general configuration

Expected behaviour

Tell us what should happen

Actual behaviour


I’ve installed Owncloud in shared hosting and I have the warning:

  • Transactional file locking should be configured to use memory-based locking, not the default slow database-based locking. See the documentation :arrow_upper_right: for more information.

I’ve read the document but I didn’t find information to shared hosting.

Server configuration

Linux Shared Hosting

Web server:

Database: MYSQL

PHP version: 7

ownCloud version: (see ownCloud admin page)

Updated from an older ownCloud or fresh install: Fresh Install

Where did you install ownCloud from: Manual

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
paste the results into and puth the link here.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.


If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/…

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/…

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Client configuration


Operating system:


Web server error log

Insert your webserver log here

ownCloud log (data/owncloud.log)

Insert your ownCloud log here

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log
b) The network log 
c) ...


i think this documentation is also valid to enable the transactional file locking on a shared hosting:

But i think the shared hosting needs to provide redis out of the box because i don’t think that you can install it on your own.

Hi Tom,

In cPanel i have configured the redis php, I’ve talked with my hosting supplier and too is active on server.

Use the command line to try to connect to the redis server with the credentials and details given by your provider to confirm it works.

Usually if everything is correct it should just work. And if you are connected using redis-cli you can run keys * to see the saved keys in redis.

Hi Eneubauer,

I have ssh access to my shared hosting but i can’t execute this line redis-cli.

Thanks for your reply


if you know that php-redis is module and the redis server is installed and if you know the connection details to the redis server then i think you can continue with editing the config.php of ownCloud as explained in the previously linked documentation:

If you don’t know the redis server connection details maybe your hosting supplier could provide these to you?

Hi Tom,

I don’t know the redis server connection details. I’ve contacted my hosting supplier, i hope they have the solution.

I share my screen with the errors:
