Erro no Enterprise Manager após mudanças de Horário de verão.

Buenas.

Este erro ocorre em 100% dos Bancos que estão configurados o EM, ao trocar a hora no server referente ao horário de verão o EM até levanta mas mostra vários erros na tela se tornando impossível trabalhar.

Para resolver este problema vou postar um script muito útil que poderá lhe ajudar apenas executando um comando.

Vale lembrar que este script é utilizado apenas para plataforma UNIX.
Antes de rodar o script, certifique-se de que a variável TZ esteja configurada no server.

Copiar e colar o script abaixo em um arquivo sh e mandar executar.

# SCRIPT NAME: set_agent_tzrgn.sh
