How to connect Dameng DB to ONLYOFFICE Docs

This guide suggests that a test bench has already been implemented in a separate feature/damengdb-compose branch:

BUILD=&lt;build-number-from-develop&gt; docker compose up -d

When installing ONLYOFFICE Docs using Docker, it’s possible to specify the available variables (DB_TYPE, DB_NAME, DB_HOST, DB_USER, DB_PWD, DB_PORT) which allow customizing your database connection.

To connect Dameng DB, add connection conditions and parameters to the initialization entry point script of the ONLYOFFICE Docs (Document Server) image.

Add a new DB type:

"dameng")
      DB_PORT=${DB_PORT:-"5236"}
      ;;

Add the function of remote database creation:

create_dameng_tbl() {
  DM8_USER=SYSDBA
  DM8_PASS=SYSDBA001

  (cd /opt/dmdbms/bin/ &amp;&amp; ./disql $DM8_USER/$DM8_PASS@$DB_HOST:$DB_PORT -e "create user "onlyoffice" identified by "onlyoffice" password_policy 0;")
  # Create db on remote server
  echo "EXIT" | tee -a $APP_DIR/server/schema/dameng/createdb.sql
  (cd /opt/dmdbms/bin/ &amp;&amp; ./disql $DM8_USER/$DM8_PASS@$DB_HOST:$DB_PORT \`$APP_DIR/server/schema/dameng/createdb.sql)
}

After these changes have been added to the entry script, Document Server is ready to initialize the connection to the database.

Create a simple compose file in which you specify the necessary variables for Document Server:

DB_TYPE: damengdb
DB_HOST: Name (dns name) of the database service in compose file
DB_NAME: Name of a database to use. Should be existing on container startup.
DB_USER: Username
DB_PWD: User password
DB_PORT: Service port with database

Mount the binary directory from the damengdb container so that the Document Server container has access to the disql utility. Refer to the docker-compose.yml to learn more.

Running a stand

To start the stand, execute the following commands:

git clone -b feature/damentdb-compose https://github.com/ONLYOFFICE/Docker-DocumentServer.git
cd Docker-DocumentServer/tests/damengdb/
docker compose up –d

Note: The database image must be available on hub.docker. We have uploaded the image v8.1.2.128 for your convenience: check it here.
