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

Scalable Database Server, HiRDB Version 8 Installation and Design Guide

20.2.7 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; (2) For a HiRDB/Parallel Server; (3) Variables used in the formulas

(1) For a HiRDB/Single Server

Condition	Formula for determining memory size (KB)
32-bit mode	9425 + {( + ) 1024}
64-bit mode	15311 + {( + ) 1024}

(2) For a HiRDB/Parallel Server

Condition		Formula for determining memory size (KB)
32-bit mode	MGR	5117 + { 1024 }
	DS	4177 + { 1024 }
	BES^*	4177 + { 1024 }
64-bit mode	MGR	5645 + { 1024}
	DS	8329 + { 1024}
	BES^*	8329 + { 1024}

^* 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):: {28000 + A + (10592 a) + (10592 b) + (10592 c) + (2264 d) + (848 e) + (272 f) + (432 g) + (304 h)}

(bytes):: {100000 + (1024 d) + (2784 i) + (2784 j) + (2784 k)}

Note

For details about other variables, see (3) Variables used in the formulas in 20.2.3 Memory size required for the execution of the database load utility (pdload).
