# Erros comuns

## ORA-12514 — Listener não reconhece o serviço

Verifique o SID ou Service Name com o administrador do banco. O valor deve ser exatamente igual ao registrado no listener Oracle.

### ORA-01017 — Credenciais inválidas

Confirme que está usando as credenciais do DataDike PAM e não as do banco Oracle diretamente. Verifique também se a conta está configurada corretamente no ativo.

### ORA-12541 — Sem listener

O banco de dados pode estar fora do ar ou a porta está bloqueada por firewall. Verifique com o administrador se o serviço Oracle está ativo e se a porta 1521 está liberada.

### Ativo Oracle não aparece para o usuário

Verifique os seguintes pontos: regra de autorização (Asset Permission) criada para o ativo, usuário incluído na regra, ativo pertence ao nó autorizado e conta de ativo configurada.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.datadike.com/integracoes/databases/oracle/erros-comuns.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
