Database properties Issue

Hi All ,

As per my understanding if we click on click on database properties and then on i- tab → then % used it define % usage of on disk usage with respect to Notes DB.

For example : If a database is showing 100 MB and when you click on %Used. If it shows 80%.

Then 80% of 100 MB is utilised by Notes DB

As i got this information from this forum itself

Now can anyone please clearify , this scenerio why it happening …

I checked my database properties it was showing

Disk Space : 158 MB , Then i click on % it was showing 98.5% then i deleted some of the mail then i again checked the properties it was showing

Disk space same as earlier i.e 158 MB but percent was reduced to 70 % and when compact run in night and i checked the properites again it was showing Disk space 158 MB and when i click on % it starting showing again 98.5% although i did not receive any new mail in my mail box .

My question is why Disk space remained same ??

And why % reduced first and then why it changed to previous ones again ?? Can you please give me logic behind it ?

Thanks in advance

Disk space remains the same because it is supposed to. The style of compaction that is normally run as an overnight server task moves things around within the file, leaving a consolidated chunk of white space at the end of the file. This makes writes to the database more efficient (since there is no need to allocate more disk space until the file is full again) and reduces the chance of file fragmentation. There is a compaction style (copy-style) that reduces the file size, but that is usually used only when a file is generating a quota warning.

The database percentage used, though, should not be returning to the old value unless additional documents are written to the database or discarded view indexes are rebuilt.

Hi Stan ,

Thanx for your post Few more question which might sound silly but will make my doubt clear,

Talking about Disk Space :

  1. Is it the size of the database or something related OS Hard disk ?

  2. Firstly when i deleted mail, % ratio gone down it mean i have created the free space on mem. then compact command run in night which in result created the contigeous mem space.

And acc. to you this % usage should not been changed to previus ones until and unless there is more data written ??

But if this is the case then why my % usage came back to old one ??

Thanks in advance
