Each node of a Teradata system can have one hybrid server that provides protected mode, multiple-threaded execution for external language procedures and UDFs to all AMPs and PEs on the node. (Protected mode UDFs are those that do not include the EXTERNAL SECURITY clause in their UDF SQL definitions.)
Each group of HybridServer fields specifies settings that the server uses when servicing procedures and UDFs written in the language specified by the HybridServerLanguage field of the group.
Example: HybridServer fields
The following group of cufconfig fields, all HybridServer3 settings, specify custom settings used by the hybrid server when running UDFs defined to have a LANGUAGE attribute of EAH.
