RE: Maxlen Excedendo

In Response To: Maxlen Excedendo (LONDONMS LONDONMS)

Olá.

Há vários posts no fórum IIUG sobre performance, basta procurá-los, ok? Cada instalação e ambiente são totalmente peculiares, ou seja, não basta informar relatórios do Informix para que seja sugerida alguma solução. O tunning deve incluir o Informix, o hardware envolvido, assim como a própria instalação do produto.

Caso ainda assim você não consiga realizar o tunning, sugerimos que entre em contato com parceiros especializados. Há vários deles que podem realizar este tipo de serviço, inclusive aqui no Brasil.
