O2F-00337: Schema not found, or no types found in schema

O2F-00337: Schema not found, or no types found in schema
Cause: A request was made to generate declarations for all the types in a database schema. Either the schema was not found, no user-declared types were found in the schema, or unable to connect to Oracle.
Action: Ensure that a login/password string was specified for OTT and that the Oracle database can be accessed with it. Ensure that the USER_TYPES table contains at least one row.

O2F-00337:未找到模式,或模式中找不到类型,
.原因:请求生成数据库模式中所有类型的声明。无法找到模式,在模式中找不到用户声明的类型,或无法连接到Oracle。,
.操作:确保为OTT指定了登录/密码字符串,并且可以使用该数据库访问Oracle数据库。确保USER_TYPES表至少包含一行。,
