20.2.14 Memory size required for execution of the free page release utility (pdreclaim) and global buffer residence utility (pdpgbfon)

Use the following formulas to determine the memory size required for execution of the free page release utility (pdreclaim) and global buffer residence utility (pdpgbfon):

ConditionFormula for the memory requirement

HiRDB/Single Server (32-bit mode)800 + W
HiRDB/Single Server (64- bit mode)800 + W
HiRDB/Parallel Server (32-bit mode)MGR800 + X
Servers specified with the -s option1Y
BES2Z
HiRDB/Parallel Server (64-bit mode)MGR850 + X
Servers specified with the -s option1Y
BES2Z
1 If the -s option is omitted, the table storage RDAREA used for processing is at the first defined server.
2 If there are multiple back-end servers, add this memory size for each back-end server.
W: Memory required for a Single Server when the database reorganization utility (pdrorg) is executing.
X: Memory required for a MGR when the database reorganization utility (pdrorg) is executing.
Y: Memory required for a DS when the database reorganization utility (pdrorg) is executing.
Z: Memory required for a BES when the database reorganization utility (pdrorg) is executing.

For details about the size of the memory required when the database reorganization utility (pdrorg) is executing, see 20.2.4 Memory size required for the execution of the database reorganization utility (pdrorg).
