-====== Database administration ======
-{{indexmenu_n>2}}
-UDR (built-in database, user data repository) is used for permanent storage of data on services and policing settings for the subscribers.
-**List of database tables**
-^ Table ^ Purpose ^
-|bindings| login and address binding|
-|bindings_multi| login and address binding for multu-subscribers (with several IPs)|
-|policing| Subscriber policing setting|
-|profile_names| Names of profiles|
-|profiles| Profiles of services and policing|
-|services| Subscriber services setting|
-|vchannel_policing| Channel policing setting|
-|ip_props| BRAS subscriber properties|
-==== Activating the built-in database ====
-<note important>UDR activation is required to support dynamic IPs and subscribers with several IPs.</note>
-UDR is activated by the configuration parameter in **///etc/dpi/fastdpi.conf//** file.
-<code>udr=1</code>
-The created database is located in the **///var/db/dpi//** directory
-<note important>You can make a copy of the database without stopping the DPI with a backup command
-<code>mdb_copy/var/db/dpi./DB</code>
-and handle further manipulations in the copied database.</note>
-==== Enlarging the DB ====
-By default, the database size is limited to 1GB. If you have more than 1 million policing profiles, you will need to increase the default size:
-<code>udr_size=2147483648</code>
-will set the DB size of 2GB.
-<note>The built-in database does not require administration and is fault tolerant. However, in rare cases, damage to the embedded database occurred. In this case, one of the following options is possible.</note>
-==== Database recovery with data transfer ====
-Stop the fastDPI
-<code>service fastdpi stop</code>
-Run the script
-<code>
-rm -rf /var/db/dpi.recover/*
-mkdir -p /var/db/dpi.recover/tmp
-for table in $(mdb_dump -l /var/db/dpi); do
-mdb_dump -f /var/db/dpi.recover/tmp/dump.$table.load -s $table /var/db/dpi
-mdb_load -f /var/db/dpi.recover/tmp/dump.$table.load /var/db/dpi.recover
-done
-rm /var/db/dpi/lock.mdb
-mv /var/db/dpi/data.mdb /var/db/dpi.recover/data.mdb.backup
-cp -f /var/db/dpi.recover/data.mdb /var/db/dpi/</code>
-Start the fastDPI
-<code>service fastdpi start</code>
-==== Deleting a database and reloading data back from an external source (billing, etc.) ====
-Stop the fastDPI
-<code>service fastdpi stop</code>
-Delete the DB
-<code>/bin/rm /var/db/dpi/*</code>
-Start the fastDPI
-<code>service fastdpi start</code>
-Reload all the settings into the database using own scripts.
-===== Experimental Section =====
-==== Restoring a database to the fdpi_ctrl command format ====
-Stop the fastDPI
-<code>service fastdpi stop</code>
-Run the script
-<code>mdb_dump -p -a -f dump.sh /var/db/dpi
-/bin/rm /var/db/dpi/*</code>
-Start the fastDPI
-<code>service fastdpi start</code>
-Run the script
-<code>chmod +x dump.sh
-./dump.sh</code>
-==== Restoring certain tables to the fdpi_ctrl command format ====
-Stop the fastDPI
-<code>service fastdpi stop</code>
-Run the script
-<code>for table in $(mdb_dump -l /var/db/dpi); do
-mdb_dump -p -f dump.$table.sh -s $table /var/db/dpi
-done
-/bin/rm /var/db/dpi/*</code>
-Start the fastDPI
-<code>service fastdpi start</code>
-Choose and run the scripts you need, **for example**
-<code>chmod +x dump.bindings.sh
-./dump.bindings.sh</code>
