http://www.winnetmag.com/Articles/ArticleID/8955/pg/2/2.html Exchange 2000 adds a new database file called the streaming store (i.e., the .stm file) to handle streaming and native Internet content. Internet clients such as POP3, IMAP, and HTTP use the streaming store exclusively. In addition, when content arrives through SMTP, Exchange 2000 pipes the content directly into the streaming store, thus bypassing the resource-intensive IMAIL conversion process that previous versions of Exchange Server used to convert native Internet content to RTF.
MAPI clients, however, don't use the .stm file. If a MAPI client needs access to content in the .stm file, Exchange 2000 converts the content on demand. The .edb file still contains properties and headers for content stored in the .stm file. The .edb files utilize the B+tree structure, but .stm files store data pages in a clustered-run style similar to that of a file system such as NTFS and better suited to the sequential access requirements of streaming content. --- To shrink these files you would need to do an offline defrag. In my experience you end up with the same size again in a few days (unless your database grew by some unregular transactions that were deleted later). regards Uso ----- Original Message ----- From: "Troels Majlandt" <[EMAIL PROTECTED]> To: "Exchange Discussions" <[EMAIL PROTECTED]> Sent: Sunday, November 02, 2003 1:58 AM Subject: Calculate size of priv1.stm - and make it smaller > Hi there ! > > (Running on Exchange 2K3 and Server 2K3) > > Is there a way of calculate the size of priv1.stm > and a way to make it smaller > btw, what is the contens of this file ? > > I wonder why it is so big, > the priv1.edb is 4Gb and priv1.stm is 1Gb also 25% of priv1.edb. > > One og the reason I ask - is that I need to know how big this file are > going to be in to priv1.edb beacuse og harddisk space. > I have priv1.edb on on partition - with (harddisk space - 10%) / number of > mailbox = max mailbox size > > But I have the priv1.stm on another partition - and if this file are > always going to be around 25% of the priv1.edb - the I ran out of harddisk > space on this partition. > > Backup is running every day so all log file are deleted. > > _________________________________________________________________ > List posting FAQ: http://www.swinc.com/resource/exch_faq.htm > Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english > To unsubscribe: mailto:[EMAIL PROTECTED] > Exchange List admin: [EMAIL PROTECTED] > _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
