Enterprise Manager Versus Sp_spaceused
Jun 29, 1999
When comparing the data space available (Edit Database dialog within Enterprise Manager) to sp_spaceused, I occasionally generate numbers that have discrepancies.
Example
Enterprise Manager shows data space available = 160.43 MB
sp_spaceused (Unallocated space = 397 MB) less log space (200 MB) = 197 MB
Even after I run (sp_spaceused @updateusage = 'true'), the problem is not resolved. Are there any known issues with space being calculated incorrectly from within Enterprise Manager? Should I not rely on Enterprise Manager and stick with sp_spaceused to find out database usage? Are there any other methods which will resolve this problem? Any help would be appreciated.
Thanks,
Karl

Can anyone comment on the engine performance difference between SQL2005 Enterprise Edition versus Standard? I'm talking generalized performance of the engine and not admin features (parallel index operations) or scaled-storage (partitioning)
( http://www.microsoft.com/sql/editions/enterprise/comparison.mspx )
The marketing literature makes note of two things:
Enterprise can use more then 4 processors
Enhanced read-ahead and scan (super scan)
(note: I cannot find anything about this 'feature')
One un-noted Feature:
only Enterprise supports 'lock pages in memory'
We are in the process of migrating from SQL2000 to SQL2005 in an OLTP environment. Based on the marketing literature; I would have chosen SQL2005-standard. But based on our limited testing, we are seeing some strange differences.
Query Performance
With MaxDOP=1 and using a large batch query (select top 1500000); SQL2005-Enterprise is twice as fast as SQL2005-Standard.
(Note: this difference persists regardless of lock-pages-in-memory setting)
CPU Utilization
In addition, taskmgr shows that SQL2005-Enterprise uses a single processor at ~90%. While SQL2005-Standard shows a single processor at ~20%.
Lock Behavior
We are also seeing lock-behavior differences. A single DML statement that attempts to modify ~5000 rows will cause Table-locks on SQL2005-Standard but obtain normal row-locks on SQL2005-Enterprise.
These empirical differences make me wonder if the engine codebase is fundamentally different between the two?
Any insight would be appreciated.

On one of our machines, all of the SQL Server 2000components except for the main Server component (SQL Servercore) itself were installed (Management tools, etc) a while agoand everything was running fine. Now I go and add/install theServer component and then Service Pack 3a.It seems that Service Manager won't start up (I get an hourglass cursor)and now I find that Enterprise Manager won't run as well. No errormessages appeared and I don't think I saw anything unusual inthe log file.However, I can use Enterprise Manager on a differentmachine and connect to the database (so the databaseitself seems to be running).Any suggestions as to what the problem might be and how tofix it? I like to see if I can repair this without havingto do a reinstall.Thanks.PF

I installed SQL Server MSDE 2000 but I can't find how to start it. Does this package include an Enterprise Manager or not? I thought that maybe it was a standard XP Pro feature. I had no problem finding it in W2000 Pro.

When I open databases, there is nothing there - not even Master, Model, Temp, Pubs, etc.
When I open the query analyzer, however, they all appear in the drop down.
What is up with that? and how can I remedy?

Has anyone encountered this error: When you are in Enterprise manager and you select a database then the tables tab and then you select a table and go to open table- select all rows, I get an error--An unexpected error happened during this operation-Query Designer encountered a query error! Please let me know if you have seen this. Also, when I access this from one networked computer I get the same error, then when I access it from another I do not!! The servers are interacting with Pivotal. The one that works does not!!

We can no longer open tables in EM. The error message is;
An unexpected error happened during this operation
[Query] - Query Designer encountered a Query error:
Unspecified error
The tables are fine - can access them other ways.It looks as if the fault is in the script used by EM. Anyway to clear this ??

I am considering upsizing my Access 2000 DB to a SQL 7 server. I was told that having SQL 7 Enterprise Manager is highly prefferd but not essential as I can maintain the upsized DB with Access 2000. The only way that I have been able to find JUST enterprise manager seems to be with purchasing the whole SQL 7 program for $1300! Microsoft cannot be that cruel, that you have to buy the whole program just for Enterprise Manager!
My questions are:
Can I download just MS SQL 7 Enterprise Manager anywhere for a reasonable fee or free?
and
if not, can I continue to use Access 2000 to maintain the SQL 7 upsized DB?

Is it possible to administer both 6.5 and 7.0 databases from the same SQL Enterprise Manager? I have read that you cannot do this because the 7.0 "plug-in" to the MMC wont work with 6.5 databases.

Hi,
I would like to know if we can present users to access details database information about the databases on a server through Enterprise Manager.
If you create a SQL login and do NOT give it access to any database, if someone logons on your server with enterprise manager, even though he does not have access to any database, he will still see the list of all database on your servers plus tons of sensitive information like database owner.
Is is possible to limit enterprise manager to only view information about database that the user has access to?
Thanks
Mark

Does anyone know how to turn off or disable the auto discovery for Enterprise Manager. Apparently our Network group is complaining that Enterprise Manager is generating noise on the network, it is not signifcant in volume but they complain it impacts there ability to detect hacking attempts on our network because it causes some false positives. I generally keep Enterprise Manager running because I will always have some manual job running from it and we have so many servers it takes awhile for them to all load when I first fire it up.

Hi,
I have SQL server 2000 client machine on my XP desktop which worked fine
until yesterday.
Yesterday, I tried to set up client access (a tool from IBM to access AS400) unsuccesfully. Since ever, Each time I try to open a table in enterprise manager, I get the following error message
"The query cannot be executed because some files are either missing or not
registered. Run setup again to make sure the required files are registered".
While when I issue a query in analyzer it works fine.
I did that several times without success. Even, I removed the whole SQL 2000
setup, rebooted my machine, ran set up again for client tools which gave the
same result. Also, I re-setup MDAC2.6 SP2 but no way.
Which files are corrupted ?and I don't understand after doing all that,
setup goes smoothly without indicating any errors, but still when you open a
table in enterprise manager, it gives the same error.
Thanks in advance

Is it possible to add custom columns to the design table interface.
For example could I add custom column for some data on want to store under a table column. I am used to vb.net and I am able to add custom properties to a control. Is this type of customization possible for SQL Server. Is it possible to add a custom tab to the tab control where columns are located at the bottom of the designer?

MMC cannot open the file C:Program FilesMicrosoft SQL Server80ToolsBINNSQL Server Enterprise Manager.MSC
This may be because the file does not exist, is not an MMC Console, or was created by a later version of MMC. This may also be because you do not have sufficient rights to the file
Note: I had admini rights on PC, and Network, I am able to run Query Analyzer....
I can remote into other boxes and run Ent. Manager also.

Hi all, met with something very scary and want to confirm if anyoneelse have met this possible bug with EM?Got a production DB, say DB_A with quite a few users in it. this day,when I look into the EM-->management-->Current Activity-->Locks/Object,I saw a lot of locking on some objects belonging to a user, say User_Abut the problem is, this User_A doesn't own a thing in DB_A!! And evenif I drop this user from DB_A, the EM GUI still showing there are quitea locks on objects owned by User_A.And if use Query Analyzer to direct query on system tables, all arefine, that is those locks are actually on another User_B, which isfine.So I've checked that the problem seems to lie in that User_B has a uid8 in DB_A whereas User_A has the same uid (8) in master db. Once Iremove User_A from master db, then the EM GUI shows no locking at all(though in system tables, there are still lockings in User_B's object).So I guess it's a bug in EM but has anyone met with this kind of casebefore?

Hi all,
I am an IT student just getting aquainted with Sequel Server. I downloaded a trial version of 2005, and am having trouble finding Enterprise Manager(which my book tells me I need to use for implementing a database). All I really need to do is learn how to design and implement database tables, with their keys and relationships, and populate them to practice querys. Can anyone help me find the applicable portion of the 2005 environment to do this? I don't have a server to hook to, just my laptop.
Thank You!
Jimbo
