The following formula is used to determine the size of a synchronization point dump file.

Formula

Size of synchronization point dump file (bytes) = Number of records in synchronization point dump file#1 x 4,096#2

#1: See (2) as follows; the obtained value is specified in the -n option of the pdloginit command.

#2: This is the record length of a synchronization point dump file.

Condition		Formula for determining the number of records
HiRDB/Single Server		{1,520 x (2 x a + 7)} 4,096 + (96 + 112 x c) 4,096 + 3
HiRDB/Parallel Server	Front-end server	(320 x b + 840) x (2 x a + 7) 4,096 + 4
	Back-end server	{1,456 x (2 x d + 7) + 64 x (2 x d + 7) x (b x 4 + f + 2)} 4,096 + (96 + 112 x c) 4,096 + 3
	Dictionary server	{1,456 x (2 x e + 7) + 64 x (2 x e + 7) x (b x 4 + f + 2)} 4,096 + (96 + 112 x c) 4,096 + 3

a: Value of the pd_max_users operand

For multi-front-end servers, value of the pd_max_users operand + 1

b: Number of back-end servers

c: Value of the pd_lck_until_disconnect_cnt operand

d: Value of the pd_max_bes_process operand

e: Value of the pd_max_dic_process operand

f: Number of front-end servers
