Цитата:
А это тогда о чем? (текст сразу под графиком) Цитата:
When using OCC the positive effect is obvious: There are much more rows available for updating (the olive bars). When we would have PCC the olive bars would not be available for updating, or in the words another process / tranaction would be blocked until all rows are processed. So when using OCC the chances for blocking is much smaller.
