Use Maximum Private Buffers per Connection (-Bpmax) parameter to control the number of private buffers a connection can request through the private read-only buffers (-Bp) parameter.

Operating system and syntax UNIX / Windows -Bpmax n
Use with Maximum value Minimum value Single-user default Multi-user default
Database Server 25% of -B 1 64 64
n
An integer specifying the maximum number of private buffers.

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 an OpenEdge database, the connection requests -Bpn private buffers. Prior to 9.1C, the maximum value of -Bp was 64. With the -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.

The Maximum Private Buffers per Connection (-Bpmax) parameter may be modified while your database is online using PROMON or through the _DbParams VST. This change will only take effect on new connections to the database.
