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):

Condition		Formula for the memory requirement (KB)
HiRDB single server configuration (32-bit mode)		800 + W
HiRDB single server configuration (64-bit mode)		800 + W
HiRDB parallel server configuration (32-bit mode)	MGR	800 + X
	Servers specified with the -s option#1	Y
	BES#2	Z
HiRDB parallel server configuration (64-bit mode)	MGR	850 + X
	Servers specified with the -s option#1	Y
	BES#2	Z

#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 19.2.4 Memory size required for the execution of the database reorganization utility (pdrorg).
