You must have a MySQL 5.7-8/MariaDB database with utf8md4 settings

Since this is not a risk-free operation it is necessary to back up the database before proceeding.

First you have to add a couple of parameters to the jdbc connection url of LogicalDOC

  1. Shutdown LogicalDOC system service/daemon
  2. Locate the file context.properties in <LOGICALDOC_INSTALLATION_DIR>/conf
  3. Edit the file context.properties by adding a couple of parameters to the value of key jdbc.url
  4. Locate the key jdbc.url and add the parameters characterEncoding=utf8&allowPublicKeyRetrieval=true
    e.g.: jdbc.url=jdbc:mysql://localhost:3306/lddemo761?useSSL=false&characterEncoding=utf8&allowPublicKeyRetrieval=true
  5. Save the file and restart LogicalDOC system service/daemon

Connect to the database using mysql client

mysql -u root -p logicaldoc

Check the status of the charset settings are OK with the query below

 SHOW VARIABLES LIKE 'char%';
MySQL queries to check charset and collation to store emoticons in LogicalDOC filenames


Execute the following SQL statements on the relevant field of the tables: ld_document, ld_version, ld_history

ALTER TABLE
    ld_document
    CHANGE ld_filename ld_filename
    VARCHAR(255)
    CHARACTER SET utf8mb4
    COLLATE utf8mb4_unicode_ci;

ALTER TABLE
    ld_version
    CHANGE ld_filename ld_filename
    VARCHAR(255)
    CHARACTER SET utf8mb4
    COLLATE utf8mb4_unicode_ci;

ALTER TABLE
    ld_history
    CHANGE ld_filename ld_filename
    VARCHAR(255)
    CHARACTER SET utf8mb4
    COLLATE utf8mb4_unicode_ci;
