19.2.7 Memory size required for the execution of the database condition analysis utility (pddbst)

The following subsections show the formulas for determining the memory size required for the execution of the database condition analysis utility (pddbst). For details about the variables used in the formulas, see (3) Variables used in the formulas.

Organization of this subsection: (1) For a HiRDB single server configuration; (2) For a HiRDB parallel server configuration; (3) Variables used in the formulas

(1) For a HiRDB single server configuration

Condition	Formula for determining memory size (KB)
32-bit mode	9,425 + {( + ) 1,024}
64-bit mode	15,311 + {( + ) 1,024}

(2) For a HiRDB parallel server configuration

Condition		Formula for determining memory size (KB)
32-bit mode	MGR	5,117 + { 1,024 }
	DS	4,177 + { 1,024 }
	BES^#	4,177 + { 1,024 }
64-bit mode	MGR	5,645 + { 1,024}
	DS	8,329 + { 1,024}
	BES^#	8,329 + { 1,024}

#: The value must be obtained for each back-end server that contains the tables and indexes subject to analysis.

(3) Variables used in the formulas

(bytes):: {28,000 + A + (10,592 a) + (10,592 b) + (10,592 c) + (2,264 d) + (848 e) + (272 f) + (432 g) + (304 h)}

(bytes):: {100,000 + (1,024 d) + (2,784 i) + (2,784 j) + (2,784 k)}

Note

For details about other variables, see (3) Variables used in the formulas in 19.2.3 Memory size required for the execution of the database load utility (pdload).
