Mar 30, 2001I have inherited a db with no clustered indexes, but composite indexes on each table. The DB has about 500 tables(1-5 gig when fully loaded), but on a given session a user might only insert 1 or 2 records in 6-7 of the tables, with about 20-30 current users 8-5PM. THe DB is kinda of a mix between low-end OLTP and DSS. For space and performance I was going to drop the existing indexes and replace them with clustered indexes. Any opinions or gotchas appreciated

Primary Key With Cluster Index
Oct 9, 2007Hi All,
One of my client having 1 million(nearly) records in a table.
I defined the table as below
1) Created table with one col(we can name it as "ID") having IDENTITY
2) Using "alter table", I created CLUSTERED PRIMARY KEY Constraint on Same field (ID)
3) The Primary key having 2 ref with another 2 tables
Now the issue is when we create or define a primary key (With Clustered Option) automatically cluster Index will be created on defined table
As such table having huge data whenever any updation or insertion against that particular table taking huge amount of time, because the cluster Index trying re-paging whole data. Because of re-paging each and every time "Transaction Log also growing in huge" (database is in full recovery mode and client wants in same mode only)
Data partitioning not posible because whole data related and current live data
I tried following options with vain
1) To Clear transaction log I suggested to take regular log backup's
2) I tried to drop cluster index and tried to implement non clustered index
Drop and re-create index is take taking huge amount of time
Even in this process I have to Re_Index remaining Index's also
Pls give me any other solution or suggestion in this regard
with Thanks & Regards

Transact SQL :: BPA On A Cluster Using Default Instance And Static Port
Aug 25, 2015Having problems running the BPA for 2012. We setup using a clustered environment, SQL Server installed using default instance, and a static port not 1433. When I try to run the BPA using the instance name it says it doesn't exist, and won't let me add a port number. However, if I use MSSQLSERVER as the instance name it runs with no port specified and returns results. I assume that it doesn't require a port because the default instance would pull from the Browser Service and the using MSSQLSERVER is the same as running the default on a standalone server. Are those assumptions correct?

Active/Active Cluster Failure - How Do You Rebuild And Rejoin A Node In The Cluster?
Aug 30, 2006We have (had) an active/active cluster. 2 physical machines,
each running their own instance, clustered together. Node1/Ins1 and Node2/Ins2.
Node2 failed and Ins2 failed over to Node1 as it should. Node2 required that we
rebuild the server (rebuild = reinstall O/S). Now we need to get Node2 back
into the cluster and get Ins2 failed back over to Node2.
Does anyone know, for certain, the correct steps to accomplish this? Obviously,
we could backup everything and completely destroy Ins2 and recreate it on Node2
then rejoin the cluster. But I'm looking for something less destructive.
Is it possible to reinstall SQL, then rejoin the cluster, and then fail Node2
over? Or will there be registry conflictions?
Any help would be appreciated. Also, if you have any links to some official
documentation, that would be great too.
Thanks
Transact SQL :: Any Reason For Difference In Order Of Columns Between Index Of Constraint And Its Statistics Definition?
Sep 5, 2015I am really puzzled by an apparent difference between table index key column order and its statistics order. I was under understanding that index statistics mirror index definition. However, in my db 2470 index ordinal definitions match statistics definition but 66 do not. I also can reproduce such discrepancy in 2008 R2, 2012 and 2014.
As per definition,
stats_column_id
int
1-based ordinal within set of stats columns
This script duplicates this for me.
BEGIN TRAN
GO
use tempdb
GO
CREATE TABLE [dbo].[ItemProperties](
[itmID] [int] NOT NULL,
[cpID] [smallint] NOT NULL,
[ipuID] [tinyint] NOT NULL,
[Code] ....
The result I get is this:
object_id      stats_name                                    Â
stats_column_list
1525580473 PK_ItemProperties_itmID_ipuID_cpID itmID, cpID, ipuID,

index_column_list
1525580473 PK_ItemProperties_itmID_ipuID_cpID itmID, ipuID, cpID,
Also a query I used to discover this in my db is:

Upgrading A SQL Server 2000 Cluster To A SQL Server 2005 Cluster
Dec 28, 2007
We're upgrading a SQL Server 2000 cluster (Active/Passive) running on Windows 2000 Server to a SQL Server 2005 Cluster running on Windows Server 2003. We can't purchase new hardware and we have no spare hardware. We also need to move from Windows 2000 Server to Windows 2003 Server at the same time. We want to keep downtime to a bare minimum.
What we were thinking was the following steps... Anyone try this?
1. Break the link between the servers.
2. Install a fresh copy of windows 2003 server on one side along with SQL Server 2005. While this step is running, the active node would still be live on Windows 2000 Server and SQL Server 2000 serving our customers.
3. Restore a copy of a backup from the active production side to the node we're upgrading and at that point we would bring the active node down, switching the active node to be the newly upgraded server.
4. As a final step, the old active node would now have the link to it broken, we would install a fresh copy of windows 2003 server on it and sql server 2005. At this point we would bring it back into the cluster and the cluster would be complete again.
Thoughts?

How To Transfer Or Migrate From Old SQL Cluster 2000 To New SQL Cluster 2000
Jul 4, 2007
I have two Windows 2000 servers (Advance Edition) to form a Windows Cluster. I also install MS SQL 2000 Enterprise Edition on the cluster to form a MS SQL cluster. Now, I want to upgrade the hardware and OS (but keep on using SQL 2000), so I install Windows 2003 server Enterprise Edition on two new servers to form a new Windows Cluster. I am planing to install MS SQL 2000 Enterprise Edition on the new cluster, so the old SQL cluster and new SQL cluster are side by side. I would like to know how to setup a new SQL cluster (I know it has problem to rename SQL Cluster name, so how to fix this problem)? And how to transfer everything (such as system databases, users database, sql user account, password and maintenance plan jobs etc) from old SQL cluster to new SQL cluster? And how to switch over from old SQL cluster to new SQL cluster?
Thanks a lot !
How SSIS Works With Cluster SQL And Non Cluster SSIS Service?
Mar 14, 2008
According to microsoft, we can cluster SSIS service but it is NOT RECOMMENDED.
http://msdn2.microsoft.com/en-us/library/ms345193.aspx
Now this is the situation that I have where I need to understand how SSIS works?
Enviornment: Active Active cluster enviornment for SQL server with SSIS server installed as stand alone as default on both node.
Name: Node 1 Node 2
--------- -------------- ---------------------
Server name: Nd1 Nd2
SQL server name: cs-nd1in01 cs-nd2in02
SSIS server name: Nd1 Nd2
BTW, this is cosolidated enviornment so there are more than one application expected and resides on each instance of SQL server.
The question is around SSIS, what would be the best practice to develop SSIS package that can work with above envoinrment.
Secnario: What if my Nd1 fails. SQL server cs-nd1IN01 will be failover to Nd2 and it will be available. But How about SSIS packages? How that understands
to use Nd2 SSIS as Nd1 SSIS is not available. Is anyone has similar experience to setup SSIS in cluster envionrment but as non-cluster service?
Please help. Thanks in adavance.
