Maximum Database size in exchange 2007

Hi Team,<o:p></o:p>
What is the maximum database size we can have in Exchange server 2007 SP3 RU8 standalone server.<o:p></o:p>
In our environment we have 1800 users hosted on the
exchange 2007 server with DB size(EDB file) of 1.61TB. What is the maximum size it can grow upto. Any response appreciated.
Thanks<o:p></o:p>

Amit just beat me to posting Harold Wong's article! :-) Since you're currently on 1.61TB the artificial limit has already been adjust via the registry setting mentioned (the article mentioned 50GB though I've seen others mention 250GB). So the maximum limit
is 16TB, but whoever adjusted things to allow your current size may have set the artificial limit as something smaller, so you'd want to check the registry to see what it has been set to in your case.
I'd also echo the comments about database size. Depending on how you handle backups then they may also play a part. Since most backups work on the basis of backing up / restoring the entire database (obviously backing up changes rather than the whole thing
each time), then the event of you needing to restore it's much easier if you have smaller databases to deal with. Splitting your mailboxes across multiple stores will help minimise the time required before you can get some users online again in the case of
a total failure. Also, if you split your mailboxes across 5 databases and then have a problem (for instance corruption) on one of them, then only around 1/5 of your users are effected rather than all of them.

  • Maximum database size Exchange 2013 Standard

    Hi,
    Does anybody is aware of database size limitation for Exchange 2013 Standard. I remember in older version there was a registry tweak to increase database limits.
    Thank you

    Hi,
    This is the official answer :
    Supported: Approximately 16 terabytes.
    Best practice:
    2 terabytes or less.
    Provision for 120 percent of calculated maximum database size.

    Never use a Format- cmdlet before sending data to Export-Csv
    Use Select-Object instead.
    PowerShell V1:
    Get-MailboxStatistics -Database "Mailbox Database" |Select-Object DisplayName, LastLoggedOnUserAccount, ItemCount, @{expression={$_.totalitemsize.value.ToMB()};label=”Size(MB)”}, LastLogonTime, LastLogoffTime | Export-Csv MailboxSize.csv -NoTypeInformation

  • Is their a maximum database size for DB2?

    Hello,
    we got a request from our business to install a new bw system on DB2 V8.2/V9 with an estimated end size of 100 Terabyte. I know, we have to ask our hardware partner, for sizing and this will include, partitioning,... But the first question from my side is "Is their a maximum size for a db2 database installed on aix?" Has anybody experience with such a huge database. At the moment our biggest database is about 1,4 Terabyte.
    Regards,
    Alexander

    Hi Alexander,
    A 100TB size sounds ambitious ... any thoughts to when the system will have that size ? It will also be interesting to understand if it's a OLTP or OLAP system.
    There is a "theoritical" technical limit on the total size of a database, but that's really beyond reason. Here is how it goes:
    A regular tablespace can be no larger than 512GB per DPF partition. A large tablespace can be no larger than 16TB per DPF partition. You can have 32767 tablespaces in a database. You can have up to 999 DPF partitions in a partitioned database server.
    Coming from that the current technical limit is:
    Non-partitioned database server: 16TB x 32767 tablespaces
    Partitioned database server: 16TB x 32767 tablespaces x 999 partitions.

    Torsten

  • Exchange 2007/2010 Console doesn't show up Exchange 2007 Databases after RBAC Implementation

    I have implemented a RBAC model after which Exchange 2010/2007 Console won't show up Exchange 2007 Mailbox Databases.
    Everything was working fine up until the Users were members of "Exchange Recipient Administrators" Group.
    I have created Custom Roles based on PArent Roles, Mail Recipients, Mail Recipient Creation, Distribution Groups & Public Folders and assigned that to a universal security group "Helpdesk operations". I removed membership for Helpdesk operations
    from "Exchange Recipient Administrators" Group and assigned the Custom Roles to "Helpdesk Operations" using the cmdlet below:

    Get-MailboxDatabase -Server "Exchange 2007 server name"
    In my environment, if I don't specify the Server parameter on Exchange 2010 Management Shell, Exchange 2007 mailbox database can't be displayed. If I specify the Server parameter, Exchange 2007 mailbox database will be displayed.

  • Exchange 2007 error relating to Public Folder Database

    Hi
    We migrated from Exchange 2003 to Exchange 2007 recently as we already had the licence so decided to take advantage of it.
    We unfortunately forgot to migrate the Public Folders as we mistakenly thought as we didn't use them they were no longer needed in Exchange 2007.
    We are now receiving 
    "Event ID 8207, MSExchangeFBPublish
    Error updating public folder with free/busy information on virtual machine BARR-EXCH-001. The error number is 0x80004005."
    On the server, I have tried http://support.microsoft.com/kb/945602 and the command
    doesnt show an error but 
    Get-PublicFolder -Identity "\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY" -Recurse | fl name,Replicas
    Still shows no entry for the NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY.  I have been advised to create a new PF store on the server as the one currently is probably empty or corrupted.
    To do this would I follow this article http://technet.microsoft.com/en-GB/library/bb123687(v=exchg.80).aspx 
    Or 
    Dismount the public folder database on the Exchange 2007 serverGo to the folder path of the EDB filedelete\move the EDB fileGo back to the management console and mount the
    public folder database. You will get a warning that one or more database files is missing. Go ahead and clickOK to mount a blank database file.?
    Any help/advice appreciated.
    Cheers
    Cheers Chris

    Hi,
    If the existing file is corrupt, I recommend you recreate a new public folder database in Exchange 2007.
    To create a new public folder database, you can refer to the following article.

  • Exchange 2007 SP3 Search Problems

    I reset all the search indices on my mailbox databases. Event viewer has told me the crawl is complete and everything checks out when I do “test-exchangeSearch”
    from PS. However, the index folders are considerably smaller than the original ones, (1.3GB vs 7GB) and only about 1% of database size. Multiple users can prove to me that searches are incomplete and not returning reliable results when just doing basic folder
    searches from Outlook 2007. help!
    Ian

    After speaking with a senior MS Engineer, if you already have SP3 applied and tried to reinstall the search as I outlined above, you have corrupt your Exchange install and the ONLY option is to rebuild the box. After reinstalling Windows and Exchange, the
    proper procedure to get search working perfectly is outlined below:
    4. If you haven’t already,
    upgrade toExchange Server 2007 Service Pack 3.
    Exchange 2007 SP3 includes several major Search-related fixes and upgrades MSSearch 3.0 to MSSearch 3.1.  This is a highly significant
    upgrade.
    5. Update to the latest available Rollup Update.
    There are some very significant search fixes in the Rollup Updates for Exchange 2007 SP3. Some of these fixes are absolutely essential to install.
    For example, Exchange 2007 SP3 Rollup Update 2 includes a fix that allows Exchange server to index emails even when the attachment cannot
    be parsed – this is the number one call generator for Exchange 2007 search support cases.
    To restate, upgrade to the very latest available Exchange 2007 SP3 rollup update, as there are many more search fixes available in the latest
    rollup updates.
    6.
    Install IFilters and register them – follow ALL the steps below.
    Install Filter Pack 1.0, which allows Exchange 2007 to index Office 2007 documents:
    2007 Office System Converter: Microsoft Filter Pack
    http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=20109
    7. Install the hotfix which addresses a known issue when search crawls a .vsd file.
    960502 Description of the 2007 Office system hotfix package (Offfiltx.msp, Visfilter.msp): December 16, 2008
    http://support.microsoft.com/default.aspx?scid=kb;EN-US;960502
    Additional Information on the hotfix:
    960166 Error message when a search process crawls a .vsd file on a Windows 64-bit operating system that is running the 2007 Office Filter
    Pack: "The filtering process has been terminated"
    http://support.microsoft.com/default.aspx?scid=kb;EN-US;960166
    8.
    Register the Filter Pack 1.0 IFilters. This is a manual process with Exchange 2007 but we have created a script to automate the process.:
    944516 How to register Filter Pack IFilters with Exchange Server 2007
    http://support.microsoft.com/default.aspx?scid=kb;EN-US;944516
    9. Install Filter Pack 2.0 which allows Exchange to index Office 2010 attachments as well as some additional file types.
    Download details: Microsoft Office 2010 Filter Packs
    http://www.microsoft.com/downloads/en/details.aspx?FamilyID=5CD4DCD7-D3E6-4970-875E-ABA93459FBEE&displaylang=en
    10. Register IFilters 2.0 with Exchange 2007.
    How to Register IFilters 2.0 with Exchange 2007 and Exchange 2010
    http://technet.microsoft.com/en-us/library/ff354976(EXCHG.80).aspx
    11. Disable signature verification for the Exchange 2007 search services by putting 127.0.0.1 crl.microsoft.com in the HOSTS file.
    Certificate Revocation List
    When the Microsoft .NET Framework 2.0 loads a managed assembly, the managed assembly calls the CryptoAPI function to verify the Authenticode signature
    on the assembly files. The CryptoAPI function checks a Certificate Revocation List
    (CRL) that is available at http://crl.microsoft.com
    . This action requires an Internet connection.
    The
    Microsoft Search Indexer service (Microsoft.Exchange.Search.ExSearch.exe)
    is a managed assembly that is loaded by Microsoft .NET Framework 2.0. After installing Exchange 2007 SP3, if the Exchange server or DNS cannot resolve
    http://crl.microsoft.com for any reason
    the outgoing HTTP requests may be dropped and an error message is not returned. This delay causes the CRL to time out and cached CRLs will expire. This affects the Microsoft Search Indexer service in such a way that any new email fails to be indexed.
    Instructions to Modify HOSTS file on the Exchange 2007 Server
    Add the following:
    127.0.0.1 crl.microsoft.com – here are the instructions:
    a. Go Start – Programs and choose Command Prompt and choose Run as Administrator.
    b. Within the Command Prompt, change to this directory (the drive will be the one where you installed the OS):
    C:\Windows\System32\drivers\etc\hosts
    c. Add the following entry to the HOSTS file:
    127.0.0.1 crl.microsoft.com
    d. Save the HOSTS file.
    13.
    Rebuild Indexes
    using ResetSearchIndexes.ps1
    How to Rebuild the Full-Text Index Catalog
    http://technet.microsoft.com/en-us/library/aa995966(EXCHG.80).aspx
    a. Go Start – Programs and choose Exchange Management Shell and choose Run as Administrator.
    b. Change to this directory (the drive will be the one where you installed Exchange 2007):
    C:\Program Files\Microsoft\Exchange Server\Scripts
    c. It is suggested that you rebuild indexes for one or a few databases at a time – use the following command to rebuild the indexes for 1
    databases called dbname1 and dbname2:
    .\ResetSearchIndex.ps1 –force dbname1 dbname2
    d. It is suggested not to run the following command unless you have 1 Exchange 2007 server only in your environment because it will cause
    all databases on all Exchange 2007 (and all Exchange 2010 servers, if there are any) to be reindexed at that same time:
    .\ResetSearchIndex.ps1 –force all
    14.
    Monitor the Application Event Log for Event ID 110 for a particular database.
    This will indicate the new index is complete for that database.
    15. After receiving Event ID 110 for a database, check to see if the size of the CatalogData folder for that database is the expected
    5% to 10% of the database size. If the size of the CatalogData folder is significantly smaller than that or if the size is a few kb or a few mb, go
    to Step 17.
    16. After you have received Event ID 110 and the size of the CatalogData folder is normal, test searching in Outlook online mode
    and OWA to make sure search is working.

  • Maximum DB Size?

    Mark, hello;
    can you please provide some kind of formula to estimate BDB JE limits?
    maximum database size?
    maximum number or records?
    maximum record size?
    maximum key size?
    thank you!
    Andrei.

    Hi,
    I'm trying to read between the lines and have concluded that you're using key ranges instead of databases, because you can't create enough databases in total over the lifetime of your app. Correct?
    Would support for 2^63 databases solve your problem? Not promising anything, just curious.
    An optimized range deletion is a nice thing, and we should probably do it in the future. But because of JE's architecture I don't think it will ever be nearly as fast as a Database removal or truncation, which is already optimized.
