In FUJITSU Enterprise Postgres 10, Mirroring Controller changes the connection setting below when connecting to an instance to detect failure of each database element.

• Application name

FUJITSU Enterprise Postgres 9.6 or earlier

• The application name is an empty string.

FUJITSU Enterprise Postgres 10 or later

• The application name is 'mc_agent'.

There is no method for changing the application name.

Therefore, if there is an application that identifies a database connection session of Mirroring Controller with the application name being an empty string, modify the process so that identification is performed using 'mc_agent'.
