short_description: Gather information about Oracle servers
description:
- Gathers information about Oracle servers.
options:
filter:
description:
- Limit the collected information by comma separated string or YAML list.
- Allowable values are C(version), C(databases), C(settings), C(users).
- By default, collects all subsets.
- You can use '!' before value (for example, C(!users)) to exclude it from the information.
- If you pass including and excluding values to the filter, for example, I(filter=!settings,version),
the excluding values, C(!settings) in this case, will be ignored.
type: list
elements: str
login_db:
description:
- Database name to connect to.
- It makes sense if I(login_user) is allowed to connect to a specific database only.
type: str
exclude_fields:
description:
- List of fields which are not needed to collect.
- "Supports elements: C(db_size). Unsupported elements will be ignored."
