Product structure preferences

BOM_enable_mem_mgt_probability_percent

Description Teamcenter can determine whether a product structure should be fully or partially expanded, depending on the quantity of server memory used. This preference specifies a percentage of free server memory, which (if exceeded) causes Teamcenter to limit structure expansion to conserve memory. It is effective for structure expansions initiated by the bomwriter and plmxml_export utilities, but not for expansions initiated in Structure Manager. Valid Values Accepts a single integer in the range 0 to 100 as its value. If set to 0, there no limit on the use of available system memory for expansion. The following examples show the effect of different settings: Example 1: Total system memory – 4 GB Total available system memory – 2.5 GB BOM_enable_mem_mgt_probability_percent= 50 Total system memory used for BOM expansion = 1.25 GB approximately Example 2: Total system memory – 4 GB Total available system memory – 2.5 GB BOM_enable_mem_mgt_probability_percent= 25 Total system memory used for BOM expansion = 0.625 GB (625 MB) approximately

Note The formula it utilizes to calculate the total system memory used is: Copy (BOM_enable_mem_mgt_probability_percent X Available System Memory) ÷ 100 Default Values 70 Default Protection Scope User preference.
