Overview

Universal Data Mover Gateway can use a database space of an existing database or you can install a database specifically for the Controller.

We recommend an initial size of 100MB.

Database Permissions

In order to install Universal Data Mover Gateway, the database user configured for the UDMG Server requires DDL (Data Definition Language) permission in the database during the install and during the migration steps for release upgrade.

...

Database Management Systems

The following database management systems are supported:

...

Once the database user is ready, the database parameters can be setup in UDMG Server configuration. The database content is initialized on the first execution and further maintained during release upgrades (see the "Upgrading UDMG Server" in the Linux and Windows installation guides)

MySQL

[mysqld]
# Fix 'ERROR 1419 (HY000): You do not have the SUPER privilege and binary logging is enabled'
log_bin_trust_function_creators = 1

mysql> CREATE DATABASE udmg;

MariaDB [(none)]> CREATE DATABASE udmg DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

mysql> CREATE USER 'udmg_user'@ IDENTIFIED BY 'udmg_password';
mysql> GRANT ALL PRIVILEGES ON udmg.* TO 'udmg_user'@ WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

[mysqld]
# Fix 'ERROR 1419 (HY000): You do not have the SUPER privilege and binary logging is enabled'

mysql> FLUSH PRIVILEGES;

PostgreSQL

PostgreSQL for Linux

1. Create a blank database on the server. An already existing database can be used, but this is not recommended.

2. Add a user that will be used as the owner of the related tables but also to authenticate with the server.
   In order to install or perform upgrades, this database user requires DDL (Data Definition Language) permission in the database during the installation or upgrade.
   Once the installation or upgrade has been completed successfully, the configured database user requires only DML (Data Manipulation Language) permissions.

...

• Install a PostgreSQL database server.

• Once the installation is complete, initialize the PostgreSQL database.

• Enable and start the PostgreSQL Server:

• Create a user for UDMG Server.

...

• Finally, change the pg_hba.conf, to allow database connection with a password. For example, for a system where the database server is on the same host as the UDMG Server, by changing this line from:

to:

The exact configuration depends on the OS and database version, on the preferred security settings, and on the system architecture.

...

For example, for a system where the database server is on the same host as the UDMG Server, by changing this line from:

to:

For a system where the database server is on the same subnet as the UDMG server, change it to:

The exact configuration depends on the OS and database version, preferred security settings, and system architecture.

The location of the pg_hba.conf can be returned by PostgreSQL Console (psql):

The current password encryption method can be returned by PostgreSQL Console (psql):
