Oracle Enterprise Manager Total Cloud Control 12c - Error: "perl: warning: Setting locale failed."

Ao tentar inicializar o Oracle Enterprise Manager Total Cloud Control 12c ocorreu o seguinte erro:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Ao executar o comando locale, pude verificar que a variável LC_ALL não estava setada:

$ locale

LANG=en_US.UTF-8

LC_CTYPE=UTF-8

LC_NUMERIC="en_US.UTF-8"

LC_TIME="en_US.UTF-8"

LC_COLLATE="en_US.UTF-8"

LC_MONETARY="en_US.UTF-8"

LC_MESSAGES="en_US.UTF-8"

LC_PAPER="en_US.UTF-8"

LC_NAME="en_US.UTF-8"

LC_ADDRESS="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"

LC_MEASUREMENT="en_US.UTF-8"

LC_IDENTIFICATION="en_US.UTF-8"

LC_ALL=

Para resolver o problema, basta adicionar no .bash_profile:

export LC_ALL="en_US.UTF-8"
