11、環(huán)境的數(shù)數(shù)據(jù)復(fù)制;VVR數(shù)據(jù)據(jù)復(fù)制系統(tǒng)主主要由下面五五個組件組成成： Repplicatted Voolume Groupp (RVGG) 復(fù)制卷卷組RVG是位位于VxVMM 磁盤組(DG)內(nèi)的的一組邏輯卷卷，RVG隸隸屬于磁盤組組的一部分，通通過定義這些些邏輯卷，應(yīng)用對邏輯輯卷的寫操作作都可以保持持以主節(jié)點(diǎn)上上同樣的順序序，來寫到備備用節(jié)點(diǎn)上。對于多數(shù)數(shù)數(shù)據(jù)庫系統(tǒng)來來說，都是由由一些特定的的 HYPERLINK /searchwhatis/292/7333792.shtml 進(jìn)程完成對磁磁盤的寫操作作，比如Orracle系系統(tǒng)中的LOOWR和DBWRR進(jìn)程，而這這些寫操作總總是依照著一一定順

12、序，從從而來保證實(shí)實(shí)例恢復(fù)中數(shù)數(shù)據(jù)的一致和和完整。比如如數(shù)據(jù)庫變化化通常在寫入入日志文件后后才會寫入數(shù)數(shù)據(jù)文件，所所以當(dāng)日志文文件和數(shù)據(jù)文文件屬于要復(fù)復(fù)制的不同邏輯卷的時時候，它們必必須被定義到到同一組RVVG中。每組RVGG最多可以包包括20488個數(shù)據(jù)卷。下面介紹SSRL和RLLINK，它它們也包括在在RVG中。 Stoorage Repliicatorr Log (SRL)SRL用于于記錄RVGG中數(shù)據(jù)寫操操作的日志，并并循環(huán)被使用用。每個RVVG包括一個個SRL。數(shù)數(shù)據(jù)在寫入RRVG中的卷卷之前，首先先要寫到主節(jié)節(jié)點(diǎn)的SRLL中。從VxVMM的角度來看看，SRL是是一個單獨(dú)的的卷，因?yàn)?/p>

13、所所有的寫操作作首先要寫到到SRL中，這這個卷需要有有較好的寫性性能，所以多多數(shù)情況下需需要對這個卷卷進(jìn)行條帶化化，并且在不不同的盤上 HYPERLINK /searchwhatis/276/5948776.shtml mmirrorr以保護(hù)數(shù)據(jù)據(jù)，同時數(shù)據(jù)據(jù)卷和SRLL卷最好分布布在不同的物物理磁盤上以以得到更好的的性能。不允許人工工直接對SRRL進(jìn)行訪問問。 Repplicattion LLinkRRLINK用于連接主主RVG和備備用RVG之之間的一個“鏈鏈接”，一個個主的RVGG最多可以有有32個RLLINK。可可以定義RLLINK的多個屬性性來調(diào)整數(shù)據(jù)據(jù)復(fù)制的參數(shù)數(shù)，比如指定定復(fù)制的網(wǎng)
