I am programming to read read sqlserver log file without shutdowning sqlserver. However it is said that the file is used by another process which I believe is sqlserver.
Is there any way to open log file without shutdowning server? I know that Log Explorer can read online log file. But I do not know the technology they are using.
Is this possible. How can one do it? Thanks for any info you have.

Hello Experts,
I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle).
PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not..
What should go here ?
->Under Class A
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)

infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.

btnOK.DialogResult = DialogResult.OK;

I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.

Hi!
I would first like to thank the person (Ray) who answered my question and also those who read it and tried to find an answer to it.
But, it didn't quite help me much, so I'll ask again; reformulate my question.
Here it goes:
I would like to know if I can make a batch file, that excutes or starts an active script (in enterprise manager go to SQL Server Group/Management/SQL Server Agent/jobs/Dbl-click on a job/then go to the steps tab and you will see that the type of the job is an active script. Or, try to see if you have an active script job).
P.S. It's not a SQL script (*.sql).
What I want to do is to start that job from a batch file.
If I can, can you give me more info on how to do it (command line, parameters), a web site, anything that can help me do that.
If I cannot do that, let me know please.
Thanks a lot!
I have a table with the following columns employeeSessionID, OpDate, OpHour, sessionStartTime, sessionCloseTime. I need to see how many users remain active per hour. I can calculate how many logged in per hour, but I am stumped on how to count how many are active per hour. I have a single table that stores login data. I have created a query that pulls out the only the data needed from the table into a temp table using this query. Also note it is possible that the sessionCloseTime is null if the device has not been logged out this would need to be counted a active.
TABLE NAME #empSessionLog Contains the time stamp data OpDate, sessionStartTime and sessionCloseTime.

can see how many sessions logged in per hour with the following statement:
SELECT
opDate,
FORMAT(DATEPART(HOUR, sessionStartTime), '00') AS opHour,
Count(*) AS Total

Order BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00') ASCResults:

Where I am stuck is how do I count the sessions that remain active per hour until the session is closed with the sessionCloseTime.
Hi
I am having some teething problems while installing SQL on a 3 node cluster. Within the Cluster configuration I have 3 Cluster Groups with each of them having their associated disk resources. All these disk resources physically exist on a SAN.
The actual cluster is running absolutely fine and I can access all the disks from their respective owner node. The problem only starts when I start installing SQL Server 2005 on this cluster. I specify the Cluster group from the Cluster Group Selection and choose the desired partition and then the error message pops up
"There is not enough diskspace on the destination disk for the current SQL Server data files. To proceed, free up disk space to make room for data files, or install the data files to a different drive"
But the disk I am trying to install it on is 264Gb and none of it is used. I have also tried to change it to a different disk within the same Cluster group but to no avail. I have even tried to install it in a different cluster group all together but I get the same error message.
I have googled around havent found anything so far. The disks have got full permissions for the account I am installing SQL with.
Any help will be much appreciated.

Anyone reading XML disk-files into SQL Server?
I have a process that I may want to do this with.
It would be a stored procedure that would read the XML attributes into 2 tables, the number of attributes could be 1-N, so I thought XML would be a good choice. Also, one of the attributes could be up to 4000 characters. I think this may limit our options, can 100-150 4000 character strings be passed in a standard call to a query/proc in SQL?
Currently the client application makes round-trip network calls to save upwards of 100 pairs of data. 1 header row, and many detail rows. All within a transaction.
I think If we move an XML file to the SQL box, then do all the import/save work on the "Server" side it would be much better. Cutting the transaction time down a lot by not doing so many round-trips at network speed...
Thoughts?
Hi
I am newbie in SQL Clustering. I have set up a Windows Server Cluster with 2 nodes and am having the following problem with Physical Disk resource for cluster groups:
My Default Cluster Group (named Cluster Group) has IP Address, Network Name, Physical Disk and MSDTC resources. In addition to that my Default SQL Server instance resources are also in this group. I had this initial set up for Active/Passive mode.
Now I am trying to set up a SQL Cluster in Active/Active mode. For this I have to install another instance of SQL Server in the existing cluster and make a separate cluster group for its resources. I made a new cluster group (SQL Instance Group) with an IP Address and a Network Name resource for this new instance but I dont have any Physical Disk resource to allocate to it. As such while installing the SQL Server Instance I get stuck when I'm asked to select the quorum disk to be used.
Is it possible to configure two quorum disks, one for each group?
What's the concept of dedicated disks resource for each sql instance in a group? Is this same as the quorum disk? If this is not a shared disk how do I configure a dedicated disk resource for my second cluster group (SQL Instance Group)?
Anyone could please help me out with this?
Hi folks,
We are going thru the process of scoping an active/active cluster at one site.

Hi All
I am trying to load DBF files into SQL server within CLR (actually if just running the select statement outside, say within the SQLQuery window, i got the same result), but with the following error:
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "VFPOLEDB" for linked server "MYDBF" does not contain the table "T8866064". The table either does not exist or the current user does not have permissions on that table.
I created the linked server in this way
EXEC sp_addlinkedserver
@server = 'MYDBF',
@provider = 'VFPOLEDB',
@srvproduct = 'My Data',
@datasrc = 'c:data'
i did not create the login since my SQL instance is running under a superaccount with all privilege.
What frustrates me is that i can read most of the dbf files, but just a few of them is not readable.
Can anyone give me some hints on it?
by the way, i am using vfp9.0
thanks

But, it didn't quite answer my question so I'll give a bit more info.

Hi,
We are trying to set up an active/active configuration of a SQL Server
cluster, and we had a few questions.
Initially, we want to have 2 Database Servers that would share the same
Database (both reading/writing to the same tables).
However, from reading the MS docs, we find out that we can have what
they call an "active/active" configuration using a Cluster but they
need to have 2 different disk sets, i.e. having 2 separate databases.
If this assumption is correct, how does the data get synchronised
between the 2 databases (that are on the 2 different disks sets)?
Can anyone help? thanks

ACTIVE/ACTIVE SQL Server 2000 Cluster
This was my plan.
Physical box - box1,box2
virtual box - virtual1
i have a active/passive cluster virtual1 (primary node box1, secondary box2)
I am creating another virtual box on box2 as primary node by name virtual2)
whenever my installation setup runs my default server name is greyed out. it always requires a instance name.
Is that the way it should work?
i can only use instance for active/active failover?
please advice

Hello folks,
have you ever heard of an Active/Active SQL Sever 2000 Cluster deployed in a pure OLTP environment?
Some 8 years ago I have learned about a bespoke solution for the SAP ERP system (not the BW!) with DB2 Parallel Server for a huge German company. Then again, I would expect that Oracle RAC might fit into an OLTP environment, although I never heard about a real world implementation.
All this led me to believe clustering is good for failover purposes, and for decision support services, not quite for OLTP applications.
So if you see a point in Active/Active Clustering and OLTP please come forward and explain.
Cheers,
Johann
P.S: For those of you who want to know: Consultants from www.hiltes.com want us to deploy an Active/Active Cluster for their Fashion 3000 Net stock software.
We run several SQL 2000 SP4 instances on IA64 active/active cluster. The OS we run with is Windows Server 2003 SP1. We have different network cards : 2 network cards teamed for production purposes in domain X and 1 network card dedicated for problem solving in domain Y.
First we configured the cluster with only the 2 teamed network cards for production purposes in domain X. Later we introduced the second network card for problem solving in domain Y.
Everything looks fine. The (virtual) SQL instance listens on two different IP adresses on TCP port 1034. If we try to make connection via isql, EM or Query analyzer than we can directly contact the SQL instance from a workstation/server within domain X but this doesn't work form a workstation/server within domain Y. However if we use the specific TCP port in the connection in domain Y the connection is setup. We wish however not to use explicit TCP ports in setting up connections.
Has anyone experienced the same problem before or has anyone an idea how to solve the problem?
I have a 2005 active/active cluster and want to apply SQL server 2005 SP2 to both node.

bear in mind what I have SSIS and SSAS and SSRS running on the active/active cluster.
what is the rigth method for applying the SP to activeactive cluster?

How can I read one external file (*.txt,*.csv) through
stored procedure in MS Sql Server 2000 ?
On the database Interbase its very simple :
[CREATE TABLE table [EXTERNAL [FILE] <filespec>]
( <col_def> [, <col_def> | <tconstraint>
]);
EXTERNAL [FILE]<filespec>
Declares that data for the table under creation resides
in a table or file outside the database;
<filespec> is the complete file specification of the
external file or table]
Please advice
