Exemplo: Criando um provedor JDBC e origem de dados usando a API Java Management Extensions e a ferramenta de script wsadmin

O código de amostra a seguir é um script JACL (wsadmin - ferramenta de script) utilizado para criar uma nova origem de dados.

Utilize esse script para criar apenas as origens de dados para as quais o produto não forneça um modelo. Para cada provedor JDBC WebSphere® Application Server suporta, o produto fornece um modelo de origem de dados correspondente. Consulte o tópico Criando Objetos de Configuração usando a ferramenta wsadmin para obter instruções sobre como utilizar o comando createUsingTemplate para estabelecer essas origens de dados. Para obter uma lista completa de provedores JDBC suportados (e, portanto, uma lista completa de origens de dados que devem ser criadas utilizando um modelo), consulte o tópico, configurações necessárias mínimas da Origem de Dados, pelo fornecedor.
