Hello, everyone:
The two SQL Server 2k (SP4) are running on W2K(SP4) in clustered A/A mode. The seconary server took over successfuly as the primary server crached. How to recover the primary sevrer?
Thanks a lot.
I have following script which i am planning to run to drop all non-clustered primary keys on a database and then created as clustered. I am using someone else's script so don't know how to modify this. Some of primary key columns are used in references in other tables.
is there anyway i can drop the existing primary keys and using their original script then create again as clustered including restoring all foreign and reference keys and unique or no unique.
DECLARE @table NVARCHAR(512), @tablename NVARCHAR(512),
@sql NVARCHAR(MAX), @sql2 NVARCHAR(MAX), @sql3 NVARCHAR(MAX),
@column NVARCHAR(MAX);
DECLARE @indexname NVARCHAR(512);
SELECT name As 'Table'
[Code] ....
I'm probably going to get shot down with thousands of reasons forthis, but I've never really heard or read a convincing explanation, sohere goes ...Clustered indexes are more efficient at returning large numbers ofrecords than non-clustered indexes. Agreed? (Assuming the NC indexdoesn't cover the query, of course)Since it's only possible to have one clustered index, why is thisalmost always used for the primary key, when by definition a primarykey will always return 1 record?Isn't it generally better to specify a non-clustered index for theprimary key, and reserve the clustered index for a column which willmost likely be used for queries that return multi-row data sets (e.g.date columns)?Also, if you are using a sequential key, clustering this will cause aninsert hotspot on the last page of the table, which can causeconcurrency problems if you aren't using row-level locking. If you'reusing a random clustered key then inserts will generally be improved,assuming you're using a sensible fillfactor, but you still lose theadvantage of using the clustered index for multi-record retrieval.I'd be very interested to hear other peoples' views on this.Phil

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

With the last table being created below, it has a clustered primary key.One of the fields it is referencing on the previous table, courseId, can NOT be unique.But without it being unique, the cluster primary key won't work.Is there another way to achieve what I am trying to do here?CREATE TABLE dbo.courseScores ( courseId varchar(20) NOT NULL CONSTRAINT FK_courseId_courseStructure2 FOREIGN KEY (courseId) REFERENCES courseStructure (courseId),
studentId varchar(20) NOT NULL CONSTRAINT FK_studentId_students2 FOREIGN KEY (studentId) REFERENCES students (studentId),
CONSTRAINT PK_courseScore PRIMARY KEY CLUSTERED (courseId, studentId)
)
CREATE TABLE dbo.objScores ( objID varchar(20) NOT NULL CONSTRAINT FK_objId_objstructure FOREIGN KEY (objID) REFERENCES objStructure (objID),
studentId varchar(20) NOT NULL CONSTRAINT FK_studentId_students3 FOREIGN KEY (studentId) REFERENCES students (studentId),
courseId varchar(20) NOT NULL CONSTRAINT FK_course FOREIGN KEY (courseId) REFERENCES courseScores (courseId), CONSTRAINT PK_objScores PRIMARY KEY CLUSTERED (objID, studentId, courseId) )

Hi,
I'm just learning SSIS. As I was following the tutorial on foreach loop container (lesson 2) to export multiple flat files in creating a simple ETL package in SSIS, I get the following error:

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "Take17.dtsx" finished: Failure.
I spent some time in understanding where could be the error. I traced it to the following place. If you take a look at the Lesson#2 in creating a simple ETL package in SSIS, using foreach loop container to import files into SQL server, as soon as I finish going through steps in configuring the file connection manager to use the variable for connectionstring, it immediately disappears. I repeated the tutorial three times exactly as I pointed out and when I reach to this step of configuring file connection manager for connectionstring, it takes the path and when I start debugging it, I get this error. When I go and check if everything is Ok, the connectionstring value is empty.
Why the value in connectionstring disappears?
Thank you.

During the installation of Adding node to a SQL Server failover cluster(On passive node) getting error like.. The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.We run the below commands but didn’t get any resolution & got the same above error .
1<sup>st</sup> Method…
1. Open console command (Run->CMD with administrator privileges).
2. net stop winmgmt
3. Rename folder %windir%System32WbemRepository to other one, for backup purposes (for example _Repository).

I am in the process of moving databases from a SQL 2005 Standard version to a 2-node 2014 cluster.All of my 2005 databases back up successfully.They all restore without issue except for one database that has a full text catalog. I get this message

I went as far as giving the folder full access to everyone temporarily and received the same error.
I ran the Advanced cluster preparation for a new sql instance on an existing cluster.
Slq Server 2012.
After is completed, it was successful, I realized I specified the wrong Instance Root directory.
Is it possible to remove what the preparation installed? Or is it possible to change the root directory?
Can I build a cluster by adding the cluster service, then the SQL instances, then add the other nodes and their passive SQL instances?I would lean to building the cluster first, the add the SQL instances.

View 6 Replies View Relatedcan we join a node in a windows cluster which is already in a different cluster?
We have this requirement as we need to setup readable secondary ( always on AG) on the third node.
We are planning to change all IPs of PRODUCTION Failover Cluster Setup. In my cluster setup ... we have 2 Physical Nodes with windows-2008, Roles are MSDTC and SQL-2008R2.
IP change for:
1. Both Nodes(Physical)

Hi all,
We have many tables which have cluster index on column with datatype 'Char(200)'.
Does anyone have script to change cluster index to noncluster for all user tables which have clustered index on a column with 'char(200)' datatype.
Thanks,

Wanted to know about difference between cluster and non cluster index with example.
When to use cluster index and non cluster index .
CREATE TABLE [dbo].[Access](
[AdminID] [int] NOT NULL,
[FnID] [int] NOT NULL,
CONSTRAINT [PK_AccessFn] PRIMARY KEY NONCLUSTERED
[Code] ....
why the cluster and non cluster indexed created on the same key?

Hi
We are planning to upgrade the SQL Server in our production environment from SQL Server 2000 to SQL Server 2005. This is a 4 Node cluster environment with 3 Databases on 3 Virtual instances. The main requirement is to achieve this with no/minimal downtime.
Could you please suggest or direct me to any documentation for the best practices used to upgrade such an environment?
Thanks

We 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

Is there a way to recover the database without defining a device to restore from?
Restore Database TestDB With Recovery
MTmace
Hi,
By mistake i've damaged my .mdf file and i have no backup on this database . However i have the transaction log intact and an older version of the database .
Is it possible to recover the database using the transaction log? How can it be done?
I do not have the transaction log backup, just the .ldf file.
Thanks to anyone who can help me.
How do I begin? I had previously installed the SQL Server 7.0 with NT Authentication and everything was fine until I Rename domain Name and Computer name. I decided to uninstall SQL Server, and then reinstall it.
From this action unable to see my database in enterprise manager. I Rename old domain and computer name again. and reinstall with Upgrade Version. but still same effect. Can anyone help? What do I need to do to get my database to work again? Any input on this will be appreciated. Thanks in advance.
I had MS SQL installed on my comp.I had to reformat my hard drive due to some problems.There was a db in the sql server which i needed.So i saved the .mdf & .sdf files.Then i installed sql server in the formatted hard drive & pasted the .mdf & .ldf files in the Data forlder in MSSQL folder.But the problem is that even after doing this the enterprise manager doesnt show that database.Can anyone help me with this?Is there any way to recover the database?
Thanks a lot
P.S.- I also have whole of the earlier MSSQL folder present in the earlier program files backed up.Would that help in anyway.
Hello, everyone:
A guy think that the DTS packages can be recoved by restore MSDB database. Is that true? Does anyone have experience on that? Thanks.

Both the new and the old server is a win2003 with SQL 2000 SP3
Is there anybody who knows how I can recover the DB?

Hello,
Is it possible to restore a SQL 2000 database with data from a transaction log?
I am not sure what happened to my database, all the data in the tables is gone. I generated a db script to create a duplicate database. I saved the .sql file on my local machine, separate from the db server, renamed the database name in the .sql file to a new database. Tested script in query analyzer for syntax, all was fine. Running it at this point would have created a new database with a different name, right?
Now my original database is empty. Can someone please provide me with information on getting my data back. Is there a way of using the transaction log to recover the data.
Thanks
I have changed the roles of primary and secondary servers due to server failure.
Can anyone advise how to revert back to previous main server? Are these any links available?

Having read your useful insight into the sorts of issues around the corruptions that folk have posted in this forum I'm interested in preparing for the day when one of our servers gets corrupted :-(
Should I expect to be able to:
Restore FULL backup from Before the corruption first happened
Restore all Tranaction log backups since
and would get me back to ground zero?
I'm thinking:
if I do a DBCC CHECKDB once a week, say, immediately after a FULL backup - then if that gives me some error messages I've got last weeks Full backup and a weeks worth of Trans Log Backups to restore - which is OK for a rare disaster.
I apprecaite that the thing that caused the corruption might be a memory or disk fault, which might also have broken the creation of the backup files too - in which case I'm fairly stuffed!
Does a RESTORE do a checksum of somesort that would detect a corruption caused by, say, a memory fault or a disk controller that wrote the block faultily [twiddled some bits, but did not report error]?
In which case continuous restores of backup files to A.N.Other server would discover the moment at which a backup was "known bad"
Am I close?
Thanks
Kristen
