從Progress-4gl數據庫獲取還原大小

Question

如何確定恢復的數據庫在完全還原後會消耗多少存儲空間？這樣做的目的是爲了確保在嘗試恢復數據庫之前有足夠的存儲空間。

Answer 1

在文檔中有一個很好的例子。如下

表108.樣品PROREST -list輸出

OpenEdge Release 10.2B1P as of Wed Oct 21 19:01:48 EDT 2009 
Area Name: Schema Area 
     Size: 11264, Records/Block: 32, Area Number: 6, Cluster Size: 1 
Area Name: Info Area 
     Size: 1024, Records/Block: 32, Area Number: 7, Cluster Size: 1 
Area Name: Customer/Order Area 
     Size: 6656, Records/Block: 32, Area Number: 8, Cluster Size: 8 
Area Name: Primary Index Area 
     Size: 112, Records/Block: 1, Area Number: 9, Cluster Size: 8 
Area Name: Customer Index Area 
     Size: 256, Records/Block: 1, Area Number: 10, Cluster Size: 64 
Area Name: Order Index Area 
     Size: 8192, Records/Block: 32, Area Number: 11, Cluster Size: 64 
Area Name: Encryption Policy Area 
     Size: 20448, Records/Block: 32, Area Number: 12, Cluster Size: 64 
Area Name: Audit Area 
     Size: 4608, Records/Block: 32, Area Number: 20, Cluster Size: 8 
Area Name: Audit Index 
     Size: 8704, Records/Block: 32, Area Number: 22, Cluster Size: 8 

使用PROREST -list的輸出來計算每個恢復區的大小：我把它​​在這裏

area-size = (Size/records-per-block) * database-block-size 

例如，恢復模式區域的大小是：

area-size = (Size/records-per-block) * database-block-size 
1,441,792 = (11264/32) * 4096 

1441792將在字節，因此由1024（1024 * 1024）除以它得到它以千字節（或兆）等

Answer 2

你必須做一些數學運算，但你可以使用prorest的-list參數。

prorest -list <restoredb> <backupfile> 

你會得到每個區域的列表，它的大小和每塊記錄一起。

Area Name: Schema Area 
     Size: 12345, Records/Block: 32, Area Number: 6, Cluster Size: 1 

將大小除以每塊的記錄數，然後將其乘以塊大小。爲每個區域做這些，把它們加起來，這應該是你的數據庫大小。
