In response to a Put Attribute request, which includes a value for an attribute previously defined by the Teradata utility, an Access Module must respond with a return code indicating whether the attribute name was recognized. This is a passive function, meaning that an Access Module can only receive the value of the provided information. An Access Module cannot actively retrieve information from a Teradata utility.
For example, if a Teradata utility needs to provide an Access Module with the value of several attributes that describe its state of operation (such as DBSVersion, ClientState, CurrDBS, or CurrTable), the Teradata utility can perform a Put Attribute function whenever one of these attributes is first defined or changed. The Access Module then receives each Put Attribute request and responds each time, indicating whether the attribute name was recognized.
