Population status logs that record status and indexing errors for each index within a catalog 將每個(gè)索引的狀態(tài)和索引錯(cuò)誤記錄到一個(gè)目錄中的填充狀態(tài)日志。
The missing indexes feature can be used to catch and correct indexing errors , whereas , database engine tuning advisor can be used to correct indexing errors and to tune the workload running on a server as a whole 缺失索引功能可用于捕獲并更正索引錯(cuò)誤,而數(shù)據(jù)庫(kù)引擎優(yōu)化顧問(wèn)可用于更正索引錯(cuò)誤,并從整體上優(yōu)化服務(wù)器中運(yùn)行的工作負(fù)荷。
The paper also does some deep research on the mesh characteristic of the mechanism , analyses the cause o f the cam profile error and index error during working , using object - oriented method , vc + + and pro / toolkit , performs second development to pro / engineer , completes entity proplasm of the cam mechanism using only few parameters , the press angle calculate module , error analysis module and curvature calculate module are built on the basis of it 然后通過(guò)對(duì)弧面分度凸輪加工中產(chǎn)生廓面誤差及工作時(shí)產(chǎn)生分度誤差原因的分析,建立了計(jì)算加工和分度誤差的數(shù)學(xué)模型。應(yīng)用vc + +和pro toolkit對(duì)pro engineer進(jìn)行二次開(kāi)發(fā),建立了弧面分度凸輪機(jī)構(gòu)的參數(shù)化設(shè)計(jì)和三維造型及壓力角、誘導(dǎo)主曲率等運(yùn)動(dòng)特性和誤差分析軟件系統(tǒng)。
