16.2.3 Formulas for shared memory used by a unit controller

Organization of this subsection
(1) 32-bit mode HiRDB
(2) 64-bit mode

(1) 32-bit mode HiRDB

The size of memory required for the unit controller in each server machine from startup to termination of the unit is the sum of the items listed as follows:

Ensure that the size of the shared memory within the entire controller does not exceed 2 gigabytes.

Lock server
  • When there is a server (FES, BES, or DS) in the unit:
For the values of the operands that are used for each server to determine the value for guest BESs in the unit subject to standby-less system switchover (effects distributed) (such as pd_lck_pool_size, pd_lck_hash_entry, and pd_max_bes_process), use the maximum value among those specified for all guest BESs in that unit, not the operand values for a particular guest BES. In the unit that is subject to standby-less system switchover (effects distributed), servers in the unit means all host BESs + all guest BESs.
In a unit subject to standby-less system switchover (1:1), servers in the unit means all accepted BESs + all alternate BESs.

MGR: System manager
FES: Front-end server
DS: Dictionary server
BES: Back-end server

(2) 64-bit mode

The size of memory required for the unit controller in each server machine from startup to termination of the unit is the sum of the following items:

Process item Shared memory calculation formula (bytes)

  • When there is a server (FES, BES, or DS) in the unit:
For the values of the operands that are used for each server to determine the value for guest BESs in the unit subject to standby-less system switchover (effects distributed) (such as pd_lck_pool_size, pd_lck_hash_entry, and pd_max_bes_process), use the maximum value among those specified for all guest BESs in that unit, not the operand values for a particular guest BES. In the unit that is subject to standby-less system switchover (effects distributed), servers in the unit means all host BESs + all guest BESs.
In the unit subject to standby-less system switchover (1:1), servers in the unit means all accepted BESs + all alternate BESs.
