Começando pelo final rs…. basta executar o script abaixo com seus devidos parâmetros.
[oracle@host script]$ limpezaLogU01.sh
É necessário passar os parâmetros de instância e tempo de retenção, caso contrario ele fará a pergunta e mostrará as instâncias disponíveis , exemplo:
[oracle@host script]$ ./limpezaLogU01.sh
DEFINA INSTANCIA: ORCL
[oracle@host script]$ ./limpezaLogU01.sh ORCL
DEFINA DIAS DE RETENÇÂO: 1 | 2 | 3 | 4 …. |10|20|30
A maneira correta é passar a instância e a quantidade de dias de retenção que deseja remover. Ele executará a limpeza e vai gerar um arquivo de log:
[oracle@host script]$ ls -l *.out
-rw-rw-r– 1 oracle oracle 831 Nov 24 14:50 limpezaLogU01_host.20161124.out
[oracle@host script]$ cat limpezaLogU01_ORCL.20170316.out
