HELP!!!!!!!!!!!!!!!!!!
I loaded SQL SP5a last night on my SQL Server and now none of my users can connect and run their applications.
I removed the virtual server and loaded the sp without any problems (so it seemed). "sa" works fine.
I am getting login failed errors:
Sql State 28000 and Sql Server 4002
Any thougts, ideas, curses would be GREATLY APPRECIATED!!!!!!!!!!!!
We are going to use SQL Sever change tracking. The problem is that some of our tables, which are to be tracked, have no primary keys. There are only unique clustered indexes. The question is what is the best way to turn on change tracking for these tables in our circumstances.
View 4 Replies View RelatedI desire to have a clustered index on a column other than the Primary Key. I have a few junction tables that I may want to alter, create table, or ...
I have practiced with an example table that is not really a junction table. It is just a table I decided to use for practice. When I execute the script, it seems to do everything I expect. For instance, there are not any constraints but there are indexes. The PK is the correct column.
CREATE TABLE [dbo].[tblNotificationMgr](
[NotificationMgrKey] [int] IDENTITY(1,1) NOT NULL,
[ContactKey] [int] NOT NULL,
[EventTypeEnum] [tinyint] NOT NULL,

I have created two tables. table one has the following fields,
Id -> unique clustered index.
table two has the following fields,
Tid -> unique clustered index
Id -> foreign key of table one(id).
Now I have created primary key for the table one column 'id'. It's created as "nonclustered, unique, primary key located on PRIMARY". Primary key create clustered index default. since unique clustered index existed in table one, it has created "Nonclustered primary key".
My Question is, What is the difference between "clustered, unique, primary key" and "nonclustered, unique, primary key"? Is there any performance impact between these?
Hello,
How do I restore a sql database that is on a clustered server from a sql database backup file that is on a non_clustered server?

I have large table with 10million records. I would like to create clustered or non-clustered index.
What is the quick way to create? I have tried once and it took more than 10 min.
please help.
Hi there, I have a table that has an IDENTITY column and it is the PK of this table. By default SQL Server creates a unique clustered index on the PK, but this isn't what I wanted. I want to make a regular unique index on the column so I can make a clustered index on a different column.
If I try to uncheck the Clustered index option in EM I get a dialog that says "Cannot convert a clustered index to a nonclustered index using the DROP_EXISTING option.". If I simply try to delete the index I get the following "An explicit DROP INDEX is not allowed on index 'index name'. It is being used for PRIMARY KEY constraint enforcement.
So do I have to drop the PK constraint now? How does that affect all the tables that have FK relationships to this table?
Thanks
What is the easiest way to remember the definitions of clustered and non clustered indexes.
View 9 Replies View RelatedI have a really super slow stored proc that does something simple. it updates a table if certain values are received.
In looking at this the matching is done on the Primary Key, which is set as a Clustered index, looking further I have another constraint, that sets the same column to a Unique, Non-Clustered.
I am not sure why this was done, but it seems to be counter productive. I have read only references to Which one is better on a primary key, but not can their be both and if it is "Smart".
Got the following message while trying to apply sp5a:

And yes, i did check the readme file, but found no problem in the PATH variable.

I have a third party app that has been 'certified' by the vendor on SQL 6.5 SP5. We are aware of the dump database issues when using SP5 and Enterprise Manager. We would like to use SP5a to get around those issues.
Is anyone aware of any other 'bugs' or problems that have come about in SP5a....
Thanks tons!

Is there a proper order to installing SQL SP5a. Should you reinstall NT SP4 after you install
the SQL SP5a?
I've got a script that runs regularly to monitor log space usage on a SQL 6.5 sp5a server. Where the log space usage is greater than 75% it then dumps the log. However the Enterprise Manager screen still shows usage as being above 75%. I'm aware that I need to run dbcc checktable(syslogs) to have EM reflect the change, and my question is:
Within my sql script how do I switch context to the database where I need to run the dbcc checktable(syslogs) command?
I currently have SP5 in a folder on the server desktop. MSSQL Server is installed on drive E:
Running setup, it finds SQL Server and shuts it down. It then returns errors about not being able to find files, though the files are actually there.
I appologize for the brain-cramps, as I know this has been discussed before, but I need HELP ASAP.
Thanks

I run replication among several SQL 6.5 Servers with SP3. Recently,
I've applied SP5a to publisher/distributor. After that, some publications
continued to replicate normally, but two of them started to act strangely -
the distribution tasks end succesfully, but it seems that no transactions
were marked for replication.
After investigating a bit, I've found that the data that continued to
replicate normally is modified by stored procedures, while problematic
tables are updated directly. Then I've tried to run isql/w updates against
problematic tables - all the changes were succesfully applied to the
subscribers. The other difference between problematic and non-problematic
tables is their size - problematic tables are much bigger and more
frequently updated.
All the subscribers are still SQL 6.5 Servers with SP3. One of them
is also a publisher that uses SP5a-upgraded SQL Server as remote
distributor. Its publications replicate OK.
I'd appreciate any explanation of the above.
Thanks

I've installed SQL Server Service pack 5a on our test lab Database and have come up with problems with my protocol. Everything works fine IF I set the Net Library to Named pipes. But before the service patch, I was running Multi-Protocol WITH TCP/IP (much faster). How can I make SQL use Multi?
Using Named pipes screws up my replication. Any suggestions???
Thanks,
Andrew
P.S. I also have SP4 on WindowsNT.
Hello,
I've a table with primary key defined as non-clusterd, now without dropping it can I modify the existing index to clustered through tsql as I had to write some migration script and in that script I wanna do this.
Thanks in Advance,

Hi:
I installed SQL sp5a on most SQL servers with no error. However, one server, a special application failed after upgrading to sp5a.
Is there a way to uninstall sp5a and back to sp3 without re-install entire SQL 6.5 on this particular machine?
thanks in advance

While installing the service pack 5a, I had the following error
"setup could not be successfully completed,
ISQL.EXE could not be executed. Please check the relevant *.Out file.
Now I am unable to start up my SQL service. When I try to start it , I get the following message:
Error : 1105, Severity: 17, State: 2
Can't allocate space for object 'Syslogs' in database 'master' because the 'logsegment' segment is full. If you ran out of space in Syslogs, dump the transaction log. Otherwise, use ALTER DATABASE or sp_extendsegment to increase the size of the segment.
Apparently 4 mb of free space in my master database was not enough for the service pack. I can't extend the size of my Master database because I can't get the SQL service to start.
Any suggestions?

I am having problems with stack dumps (as many as 12 a day) at a production site running NT 4.0 SP4 with Sql Server 6.5 SP5A. I've tried running every diagnostic utility on the server but it shows no problems. Before I open a ticket with Microsoft on the stack dumps, I'd like to upgrade the server to NT Service Pack 6A. My question is, do I need to re-install SqlServer SP5A? Will the NT Service Pack 6A invalidate SQL SP5A?
TIA,
Mike
Hi all,
I recently upgraded to SQL 6.5- sp5a. I run DBCC TEXTALL as part of my nightly maintenance. Our db is about 3 GB and is heavy on text
fields. Since the upgrade, DBCC TEXTALL hangs up the server until I reboot it. The last message in the error log is "Warning:
out of RA slots... comfigure more RA slots." (or something like that). This never happened before.
BOL says don't monkey with the RA slots per thread, so
I've been adjusting the number of RA worker threads. I raise it, bounce SQL SERVER, and try to run the DBCC TEXTALL again.
Same results. Eventually I got up to 10 RA worker threads, at which point I got an "IO buf_wait" error, which also hung up the server.
I've read that increasing RA worker threads will eventually run you out of buffer space, and it looks like that's what happened.
I'm beginning to think that the problem isn't really with isn't really with the number of RA worker threads I have configured,
but rather with something that sp5a changed. Or maybe DBCC TEXTALL is running into some sort of corruption it can't handle...
Or something...
So, I'm reading up on the relationship between buffer cache, RA, etc., but
the sad fact is that information on that low down level is hard to find, and I don't understand most of it anyway.
Any suggestions, reading recommendations, comments, or jeers would be highly appreciated.
we have a client that just upgraded to sp5a and are encountering problems...one stored procedure seems to routinely become corrupted, and does not complete correctly. however, it does not error out, and the only way to tell that it did not complete successfully it to query the data.
the only solution that i have found to this problem is to recreate the procedure. i have tried using sp_recompile to force a recompile at next runtime, and the problem still occurs. i have tried recreating the calling procedure, and recreating procedures it calls, but neither fix the problem.
after recreating the procedure, it continues to run fine for anywhere from 1 hour to 8 hours, and then starts to fail again.
microsoft so far has not been able to give us help in diagnosing this, and i am coming up with nothing in my own investigations.
has anyone seen a problem like this in sp5a?
also, it is occurring on 5 similar dbs that are on the same server...
thanks

When running Enterprise Manager from my desktop pc to try and expand a database device I am unable to do so. The size shown is negative, and the max size is the same, with the 'Change Now' box greyed out.
When I log on directly onto the server I can easily expand the db device. There is lots of free space on the server.
Our set up is quite small with four NT workstations and two NT servers with SQL Server 6.5 on them. All these six machines are in the same workgroup. The workstations are on a separate floor to the servers, which are in the computer room. I have a feeling this is a networking issue. Can anyone suggest why this is happening?
Hi,
Has anyone encountered this?
After applying SP 5a I found out that my SQL strings with sums and groups produced double rows. I found out that grouping one column (type CHAR(6)) produced two distinct rows of the equal values.
All the values in that column have 4 characters, but it seemed like some distinct values were grouped by the whole field length i.e 6 characters. I haven't seen earlier that those blanks after field value change the grouping results.
When I transferred the table and data to old SQL Server without any SPs, query showed distinct values correctly.
The sort order and other settings are the same. Can anyone tell where to look for help?
TIA, Al
Hi
I've recently upgraded 4 sql servers to sp5a and have just found that BCP fails on all of them with a DR Watson error. I did reinstall the Nt sp after installing sql server sp5a.
Can anyone help ?

Has anyone gotten clustering to work via the Cluster Wizard in SP5a?
I've got two ProLiant 5500's with the Compaq Clustering S/100 option. I've done a fresh install of NT Enterprise 4.0 SP3, then installed clustering with the Compaq S/100 drivers... everything fails over nicely, can make shares off the virtual server, etc. I then install SQL Server 6.5 EE, then apply SP5a -- so far, so good.
Now I try to run the clustering wizard. The wiz prompts me for my SA password. I enter it, and it gives me a message box that it can't start or log onto the database... but when I look in the event log it appears to have logged on successfully with a Non-trusted connection.
Thanks for the help...
I would like to find information on Clustered and Non-clustered indexes and how B-trees are used. I know a clustered index is placed into a b-tree which makes sense for fast ordered searching. What data structure does a non-clustered index use and how? I tried to find info. on the web but couldn't get much detail...
View 3 Replies View RelatedI have a table<table1> with 804668 records primary on table1(col1,col2,col3,col4)
Have created non-clustered index on <table1>(col2,col3,col4),to solve a performance issue.(which is a join involving another table with 1.2 million records).Seems to be working great.
I want to know whether this will slow down,insert and update on the <table1>?
Hello,
Just in case anybody has had this problem after applying service pack 5a.
a stored procedure that sets serial numbers on records on a temporary table is skipping every other record.
I ran the code manually on isql and could not replicate the error, however when re-compiled on stored procedure it fails misserably.
when is Microsoft going to release a service pack that actually works?
Did you know that Executive does not recognize 2000 as a leap year?
If anybody has any suggestions on this problem, besides the obvious (using a real table) please write back
thanks.

Pseudo data-admin
ACNY
the query:
SELECT a.AssetGuid, a.Name, a.LocationGuid
FROM Asset a WHERE a.AssociationGuid IN (
SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada
WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
takes 30-60 seconds to run on my machine, due to a clustered index scan on our an index on asset [about half a million rows]. For this particular association less than 50 rows are returned.
expanding the inner select into a list of guids the query runs instantly:
SELECT a.AssetGuid, a.Name, a.LocationGuid
FROM Asset a WHERE a.AssociationGuid IN (
'0F9C1654-9FAC-45FC-9997-5EBDAD21A4B4',
'52C616C0-C4C5-45F4-B691-7FA83462CA34',
'C95A6669-D6D1-460A-BC2F-C0F6756A234D')
It runs instantly because of doing a clustered index seek [on the same index as the previous query] instead of a scan. The index in question IX_Asset_AssociationGuid is a nonclustered index on Asset.AssociationGuid.
The tables involved:
Asset, represents an asset. Primary key is AssetGuid, there is an index/FK on Asset.AssociationGuid. The asset table has 28 columns or so...
Association, kind of like a place, associations exist in a tree where one association can contain any number of child associations. Each association has a ParentAssociationGuid pointing to its parent. Only leaf associations contain assets.
AssociationDataAssociation, a table consisting of two columns, AssociationGuid, DataAssociationGuid. This is a table used to quickly find leaf associations [DataAssociationGuid] beneath a particular association [AssociationGuid]. In the above case the inner select () returns 3 rows.
I'd include .sqlplan files or screenshots, but I don't see a way to attach them.
I understand I can specify to use the index manually [and this also runs instantly], but for such a simple query it is peculiar it is necesscary. This is the query with the index specified manually:
SELECT a.AssetGuid, a.Name, a.LocationGuid
FROM Asset a WITH (INDEX (IX_Asset_AssociationGuid)) WHERE
a.AssociationGuid IN (
SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada
WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
To repeat/clarify my question, why might this not be doing a clustered index seek with the first query?
So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this:
When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004
Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing?
If so does this "pseudocode" example also cause this to occur:
sqlstring="select * from item where itemid=12345"
rs.open sqlstring, etc, etc, etc
rs.Fields("ItemName")="My New Item Name"
rs.Fields("ItemPrice")=1.00
rs.Update
Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?
We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?
