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 9 System Definition.
You should define local buffers when both of the following conditions apply:
Since UAPs that are always connected to HiRDB have a major impact on the system (in terms of use of memory, server processes and the like), do not define local buffers for such UAPs.
