Jun 4, 1999Is there a way to see how much memory your current SQL Server install is using? I recently had to do some reconfiguring, and although it went fine, I'd like to build a spreadsheet model so I could see what different parameter values do to memory usage. I'm kinda surprised there isn't one already.
And yes, I realize that 99% of the configuration options go away in 7.0. We're going to have 6.5 here for a while yet.

Apr 16, 2008
In my enrv. DBA just migrated SQL Server 2000 Databases from WINDOWS 2000 to WINDOWS 2003 Enterprise Edition and the same SQL version. The problem which i need to analyse
1. Why the full backup size is occupying only 70GB when DB size is 120GB?
Here is the situation
Full Backup is taken once every day ---- 70gb
Diff Backup Taken every 3 hrs till 5 PM ----- size is 50GB
Transaction log backed up every 10 min uptill 8 PM ----- not a big size
I am really confused as to why Full DB Backup is taking only 70GB.............Can some one please throw a Light on how the SQL Server 2000 Backup functions.

SP2 Replicating With Pre-SP2?
Jul 23, 2007Hi gang,
I'm 99% sure this is possible, but I wanted to confirm before I go upgrading one box in our replication scheme without having to do all the others (which are geographically dispersed):
Can an SP2 box replicate (merge replication in our case) with pre-SP2 servers? Most of our servers don't even have SP1 applied, and we're ready to upgrade, but I want to be sure I can do them one at a time rather than all at once.
Cheers,
Matt

Replicating Design Changes
Mar 5, 2005I am trying to create an auto off-site backup of an entire database. This would include databases and users. It should also include changes made throughout the day.
Something challenging about this is I want it to also include design changes that may have been done throughout the day.
I understand log shipping or replication can deal with the data part of my solution. But how can I copy over the logins, users, and design changes?
Is it possible to have design changes replicated from publishers to subscribers?

Replicating SysTables
Apr 21, 2004Good Day Gurus
I posted a question about replicating logins to the database and the answer i got about doing a DTS to transfer logins is not good for me, is it possible to replicate syslogins tables so that i can do this if so, how because they are not listed Database and Publications when i try to create a publication, only individual created databases can be seen.
The reason for this is because when the DBA decides to change the user permission, i want the info to be merge replicated to the subscriber. At this moment i can run the DTS to transfer the login but it won't know when the logins have been updated and hence i won't know when to run it.
Thanks in advance
Replicating Data
Mar 31, 2008Hi,
I am very new to SQL Server. Plenty of SQL knowledge but the whoe SQL server enviornment is new.
I am working with SQL Server 2005. My task is to generate reports without affecting our live database. I have setup a second server and installed SQL Server 2005 on that too. My thought was that maybe I could mirror or replicate the table I require over to this new server and run my queries from here. Is this easy to do ?
I read that mirroring might not work as it is solely for back up /fall over purposes and that data on the mirrored server would not be accessible.
I have also been looking at SSIS but at the moment this is all a bit like double dutch to me ! Can anyone point me in the right direction, preferably somewhere beginner friendly ie not overly complicated !!
Thanks a mill,

Replicating DDL In Sql 2005
Aug 11, 2006I am using Sql 2005 and merge replication. I am relying on the feature where schema changes are replicated to subscribers but I have come across a situation where schema changes stop being replicated.
This is the scenario:
I create a database and publish it for merge replication.
I add subscribers.
If I need to change the published database I can use ALTER TABLE ddl and the subscriber gets the changes.
If I have to add or remove a merge article as part of a database change I specify the @force_invalidate_snapshot=1, @force_reinit_subscription=1. No any ALTER TABLE statements following the article change will NOT be replicated.
Is this a known 'feature'? Is it because @force_reinit_subscription is set to 1?
Can anyone help me?

Help Please Some Data Not Replicating
Oct 10, 2006Hello,
We have four mobile devices that are set up for merge replication via the web. We are not receiving errors but some of the data is not coming over to the devices. If we manually add a record that record will come over, but there is data that is on the server that isn't on the devices. If we run the snapshot for each device (We're using host_name as a filter) nothing happens. If we do validation check we get errors. If we reinitialize all devices it works but the next days data (sql job populates data to the publisher db at night) isn't on the device after syncing the next morning. Any help would be appreciated.

Replicating UDT's To Subscribers
May 21, 2007I have a sql 2005 publisher and distributor and a sql 2000 subscribers. for some reason on one of the subscribers i'm getting errors that it can't replicate the UDT's. i tried a new snapshot and made sure it was set not to replicate UDT's but i'm still getting Create Type errors.
would anyone have any idea why it's trying to create UDT's at the subscriber when i specify not to replicate UDT's?
Replicating Schema Changes
Jun 26, 2006Hi there,
I'm using Sql 2005 merge replication and I have noticed something, I'm not sure if this is true or not:...
My publication is set to replicate schema changes (replicate_ddl = 1). Now, I have noticed that schema changes are only replicated if the current snapshot is valid. Is this right? If so why?
My next question carries on from the first. If I'm about to run a TSQL script on my publisher that will add a column or two to a published table, how do I ensure my snapshot is valid inorder for the ddl changes to be replcated? Should I be using:
EXEC sp_mergearticlecolumn
@publication = <publicationname>,
@article = <article name>,
@force_invalidate_snapshot = 1,
@force_reinit_subscription = 1
on each table I modifiy, after I have added the new column?
Thanks for your help

Replicating Schema Only
Mar 13, 2006Hi,
I have a database that is being set up for merge replication (Sql 2005), but there is one table that I only want the schema replicating, not the data - I never want the data to be replicated in either direction. I can see from sp_addmergearticle that you can do something like this for sp's or functions but is it possible to do this for tables?
Regards

Replicating Roles
Nov 13, 2006Hello,
I use a merge replication between Sql Server and Sql Server Express.
When I enable a DB for .NET features (eg RoleManager), I have new tables and roles that are created and some GRANT are given on SPs.
When I replicate these DB to another one, none of my roles are replicated and I also loose my roles. Is there a way to replicate also the roles and the permissions ?
Thanks

Error - Output Param - SP - Size Property Has An Invalid Size Of 0
Nov 14, 2007Using C#, SQL Server 2005, ASP.NET 2, in a web app, I've tried removing the size from parameters of type NCHAR, NVARCHAR, and VARCHAR. I'd rather just send a string and let the size of the parameter in the SP truncate any extra chars if need be. I began getting the error below, and eventually realized it happened only with output parameters, as in the code snippet below.String[3]: the Size property has an invalid size of 0. par = new SqlParameter("@BusinessEntity", SqlDbType.NVarChar); par.Direction = ParameterDirection.Output; cmd.Parameters.Add(par); cmd.ExecuteNonQuery();What's the logic behind this? Is there any way around it other than either finding out what the size should be, or assigning a size larger than would ever be needed? ThanksMike Thomas

Jun 26, 2007I am wondering if there is a way to replicate changes in a SQL 2000 DB to 2005 without backing up the DB and restoring it in 2005.
We are running an ERP system using SQL 2000 and are moving to a later version that supports 2005 and we want to test it out before going live but I'd like to sync with the current system from time to time instead of having to convert the DB and get it ready again and again everytime I want to update the data.
Thanks for any help you can offer,
