Oracle De-install Utility
Remover o Oracle Database pode dar muito trabalho, e você pode esquecer de remover algo no processo. Mas o Oracle Database 11gR2 tem um utilitário para desinstalação completa do produto – que pode ser baixado a parte e sem custo, na mesma página onde são baixados os outros arquivos que fazem parte do Oracle Database: por exemplo, esta é a página de download para Linux x86-64: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-linx8664soft-100572.html
É impressionante ver que o desinstalador é baixado como um arquivo compactado de 135MB. Bem, se o RDBMS todo são alguns Gigabytes, é compreensível que o desinstalador seja deste tamanho.
Veja na demonstração abaixo, a utilização é simples (basta indicar o ORACLE_HOME que será desinstalado) e ele funcionou sem problemas.
