Nextcloud accept larger upload filesize
By default, Nextcloud only accept small upload filesize.
This is due the configuration of php.ini in Apache, and the settings in Nextcloud itself.

By the way? Have you already update your php to version 7? Read here how to do this: Nextcloud update php5.6 to php7.0

In this example we use a new maximum file size of 200 GB. We change the php.ini as follow:
- Open php.ini by your favorite editor, for example ‘nano’.
  sudo nano /etc/php*/apache2/php.ini
- Find upload_max_filesize and change it to 200 GB (along with post_max_size)
- Save the file
- Restart apache
  sudo service apache2 restart
- Edit admin settings in NC to reflect php.ini

Use an external MySQL database like Synology
By default Traccar Server uses embedded H2 database. If you want to use MySQL database engine you need to replace following lines in configuration file:
```
<entry key='database.driver'>org.h2.Driver</entry>
<entry key='database.url'>jdbc:h2:/home/user/Documents/traccar/target/database</entry>
<entry key='database.user'>sa</entry>
<entry key='database.password'></entry>
```
Configuration parameters for MySQL (replace 127.0.0.1, [DATABASE], [USER], [PASSWORD] with appropriate values):
```
<entry key='database.driver'>com.mysql.jdbc.Driver</entry> 
<entry key='database.url'>jdbc:mysql://127.0.0.1:3306/[DATABASE]?allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=latin1&amp;sessionVariables=sql_mode=ANSI_QUOTES</entry>
<entry key='database.user'>[USER]</entry> 
<entry key='database.password'>[PASSWORD]</entry>
```
NOTE: Traccar will create tables for you, but you need to create database with selected name by yourself.

Configuration of devices

RF-V16

Device transmits on port 5005. Traccar listens default to this protocol (H02) on port 5013. Make port forward in router 5005 → 5013 or swap port numbers in .xml configuration file.

Known issues

Using Synology MySQL database (update)

= (UPDATE) PROBLEM SOLVED in version 3.4 = You can make version 3.3 work with the Synology MySQL database with a small modification. Change in the .XML configurationfile ‘UTF-8’ to ‘latin-1’. The developer know this problem and it will be solved in the near future.

Version 3.2 works great without this specific modifcation
