Maximum Private Buffers per Connection (-Bpmax)
n
An integer specifying the maximum number of private buffers.
The Maximum Private Buffers per Connection (
-Bpmax
) parameter is a broker setting which controls the number of private buffers a connection can request through the Private Read-only Buffers (-Bp
) parameter.The number of blocks in the database buffers is controlled by the Blocks in Database Buffers (-B) parameter. Up to 25% of the blocks created may be allocated for use as private buffers. When a client connects to a Progress database, the connection requests
-Bp
n private buffers. Prior to 9.1C, the maximum value of -Bp
was 64. With the new-Bpmax
parameter, the broker may override this limit by allowing the value of -Bp
to be up to 25% of -B.NOTE: Each use of a private read-only buffer reduces the number of public buffers. The total number of private buffers for all simultaneous users is limited to 25% of the total blocks in database buffers.
