Temporary bypass exchange std. edtion 16gb Limit - 2006/05/10 11:29
howto temporary bypass the 16gb limit in exchange std. edition
SYMPTOMS
The Microsoft Exchange 2000 Server message database (MD automatically shuts down and does not restart when it reaches the maximum size limit that is permitted. This behavior is by design to prevent the database from trying to insert more data into the database file than it was designed to hold. Frequently, you experience this behavior when you are running Microsoft Exchange 2000 Server Standard Edition. Exchange 2000 Server Standard Edition limits the database size to 16 gigabytes.
A new update to Exchange 2000 has been developed that permits you to temporarily increase the database size limit by 1 gigabyte. By increasing the size limit, you can selectively remove unnecessary database content, defragment the database, and reduce the database size to a manageable level that is below the defined limits for database size.
RESOLUTION
Update Information
A supported feature that modifies the product's default behavior is now available from Microsoft, but it is only intended to modify the behavior that this article describes. Apply it only to systems that specifically need it. This feature may receive additional testing. Therefore, if your system is not severely affected by the lack of this feature, Microsoft recommends that you wait for the next Microsoft Exchange 2000 Server service pack that contains this feature.
To obtain this feature immediately, contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services censuur numbers and information about support costs, visit the following Microsoft Web site:
http://support.microsoft.com/default.aspx?scid=fh;[LN];CNTACTMS
Prerequisites
Because of file dependencies, this update requires Microsoft Exchange 2000 Server Service Pack 3 (SP3). For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
301378 How to Obtain the Latest Exchange 2000 Server Service Pack
Create New Registry Value
The update requires you to create a new registry value to enable this feature.
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To add the registry entry to the Exchange 2000 computer, follow these steps:
Click Start, click Run, and then type regedt32.exe.
Locate the following key in the registry: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSExchangeIS<Exchange Server Name>Private-<long hexadecimal string>
On the Edit menu, click Add Value, and then type the following in the Value name box: Temporary DB Size Limit Extension
Select REG_DWORD for the data type, and then click OK.
Enter a value of 1, and then click OK.
Quit Registry Editor.
If the Temporary DB Size Limit Extension registry value exists for a specific database and if the value is set a value other than zero, the database size limit (if any) is increased by 1 gigabyte. However, this registry value is not read dynamically; it is only read when a database is started. When the Exchange Information Store starts, an event 9657 will be logged as a warning to inform you that you are using a temporary database size limit.
STATUS
