Information is output to the system log when the free page release utility (pdreclaim) is used to release the free pages of tables or indexes. Table 18-18 shows the formulas for determining the amount of log output. If row partitioning is used with the tables or indexes, this calculation must be performed for each partitioned RDAREA. For a HiRDB/Single Server, determine the total amount of log information calculated from each row partitioned RDAREA. For a HiRDB/Parallel Server, determine the total amount of log information calculated from each row partitioned RDAREA for each server.

Table 18-18 Amount of system log information output when the free page release utility is executed

Type	Amount of system log information (bytes)
Tables	140n Calculate when the -o option is not specified. 504m
Indexes	{((k + 14) (j - 68)) 1408 + k + 12 h + 906} n When the -x option is specified, the amount of system log information is added when the free page release index is a unique index, a primary key, or a cluster key that specifies UNIQUE or PRIMARY. {m - n - (((k + 14) n) ((j - 68) 2))} (j - 56) 0.7
Segments	2380p

h: Index levels

j: Page size (bytes)

k: Index key length (bytes)

m: Number of used pages (excluding full pages)

n: Number of used free pages

p: Number of used free segments
