Base não conecta e desmonta automáticamente.

Estou com um probleminha...Instalei o servidor Oracle Xe e funciona perfeitamente...Conectado a um sistema em VB ele funciona tranquilamente...Foi criado um utilitário que todos os dias a 00:30 ele dispara o comando "exp usuario/senha file=backup.dmp log=backup.log owner=CADASTROS statistics=none"Ai vem um problema... algumas vezes ao tentar entrar no Sistema usando a Base Oracle ela esta desmontada... e para voltar a funcionar, tenho que Parar a Base e Iniciar novamente.Logo no inicio não acontecia... mas sempre depois de 2 ou 3 dias começa a dar esse problema todos os dias.Alguem pode me dizer se o comando EXP requer que a base seja montada novamente depois??? ou onde posso localizar o log do servidor para poder encontrar o que pode estar acontecendo?Obrigado a todos.

Muricy, Verifica o ALERT.log da sua instância Oracle, que se encontra no diretorio BDUMP. O EXP não precisa estar em MOUNT, alias, ele nem funciona em MOUNT, somente OPEN! Alguma rotina de backup COLD deve estar sendo realizada na empresa e esqueçeram de colocar o comando ALTER DATABASE OPEN; Abraços,

Alphamek, Como posso verificar essas informações para lhe passar?Fiz a instalação padrão do Oracle XE e não mudei nada.

[alphamek 2]

Para verificar faça o seguinte:

 

conect-se no banco de dados com o usuário SYS AS SYSDBA, exemplo:

 

C:\> set ORACLE_SID=XEC:\> echo %ORACLE_SID%C:\> sqlplus sys as sysdba

Depois, para verificar o serviço de ARCHIVE, basta executar:

 

SQL> archive log list

E coloque a resposta aqui no fórum.

 

Abraços, ;)
