Local buffers are maintained in the process private memory and are used for input/output of data that is stored in an RDAREA on disk. The types of local buffers are as follows:
Local buffers are defined for each UAP in the UAP environment definition. By allocating a dedicated local buffer to a UAP, it is possible to avoid global buffer contention with other UAPs or waiting for buffer locks. For details about UAP environment definition, see the manual HiRDB Version 8 System Definition.
You should define local buffers when both of the following conditions apply:
Because a UAP with an enduring connection to HiRDB has a large influence on the system (memory pressure, process contention, etc.), definition of local buffers in such a case is not appropriate.
