In short
Oraoledb is a driver made in the standard OLEDB that serves to connect to Oracle databases.
If this message appears in your company’s application, it is most likely that the bank is down, falling or is too busy processing slow queries.
Long explanation
First, understand that OLEDB is an API developed by Microsoft based on the COM, Component Object Model, a model invented by Microsoft itself to ensure interoperability between applications. This API represents a COM interface library that allows universal access to various data sources, including non-SAS data sources such as Microsoft Excel, Exchange Email Server and Directory Services (Active Directory).
The design of OLEDB focuses on the concept of consumer (Consumer) and provider (Provider).
Each provider implements a set of COM interface standards to handle consumer requests. A manufacturer can implement optional COM interfaces to add even more functionality to its provider.
The Oraoledb is an implementation of an OLEDB provider for access to Oracle’s database.
See the Oracle diagram illustrating the OLEDB flow.

It is possible that it is because it is too short and does not have many details. Mainly, when you cite the error in the system of your work. You did not put the conditions for such an error to happen, there is no code, etc. Another reason might be that your question about Oraoledb does not fit perfectly in the definition of programming, which is the focus of Stackoverflow. Perhaps a moderator could point that question elsewhere like the Super User.
