Transaction-Log Reader Subsystem Errors On: The Process Could Not Execute 'sp_replcmds'
Apr 10, 2006
Hello,
I currently have a Transactional Log reader agent failing with the below error:
The process could not execute 'sp_replcmds'
Error: 14151, Severity: 18, State: 1
SQL Server Assertion: File: <logscan.cpp>, line=2223
Failed Assertion = 'm_noOfScAlloc == 0'.
Stack Signature for the dump is 0x24642FE5
Error: 3624, Severity: 20, State: 1.
SQL Server Assertion: File: <logscan.cpp>, line=1985
Failed Assertion = 'startLSN >= m_curLSN'.
Stack Signature for the dump is 0xD7150BD4
Now, I understand that SP4 is supposed to fix a similar issue. SP4 has been installed and the errors keep happening. I do notice that the hot fix mentions different line numbers than the above errors. Does anyone know if this is a new bug? If not can someone explain the fixes to me, thanks,

Free Some Space Of The Transaction Log .. Urgent Help Please .!!
Apr 11, 2002Hi friends ,
I have a database with around 2 GB space for the data and 5.8 GB for the
transaction log .
Now the problem is i do not have any more space on the system and data files requires more space than 2 G.B to execute some stored procedures .
Is it possible to decrease some space of the transaction log , say from 5.8 GB to 2 GB and allocate it to the data files .
My data and log files are on different drives . I did not find anything related to this topic in the BOL .
Can somebody help me with this problem ? Anthing related to this issue will be of great help to me since i have no expertise in this field .
Thanks and Regards

SqlDataReader Reader Connection Closing Before Dt.Load(reader)

The Log File For Database 'Home_alone' Is Full. Back Up The Transaction Log For The Database To Free Up Some Log Space.
Feb 4, 2008
Hi all
Iam working in Prodcution ENV,Please help how make space
The log file for database 'Home_alone' is full. Back up the transaction log for the database to free up some log space.
DB Engine :: Will Transaction Log Backups Not Free Up Log During Full Backups
Nov 15, 2015The space allocated to the Log in question is 180 GB. During this time period I was running TLog backups every 5 minutes, yet the log continued to chew through to 80 GB used, even after the process was complete and a final TLog backup had been taken. It continued to stay very large until the Full backup was complete -- or something else that I'm unaware of completed. Like every other DBA I typically take a TLog backup to shrink the log, but what appeared to be the case here was the Full completed and it released the used log space. All said, will Transaction Log backups not free up the log during Full backups?

Log Reader
Aug 22, 2007We dont want to use triggers or replication to capture changes in a set of tables; we have the same problem in Oracle and we use LogMiner to do so. We have been looking for similar tools in SQL Server but the ones we have found so far dont seem to fulfill our requirements (Redgate and Lumigent).
Does anyone know any other third party application that can read a SQL Server log and extract changes filtering by table name?
Thanks.

try
conn = New SqlConnection(ConfigurationManager.ConnectionStrings("myConnection").ConnectionString)
conn.Open()
cmd = New SqlCommand
cmd.Connection = conn
cmd2 = New SqlCommand
cmd2.Connection = conn
dim reader As SqlDataReader = cmd.ExecuteReader
Right this works and I can access reader fine
but as soon as I do the following I get an error
reader2 = cmd2.ExecuteReader (reader2 is already declared just not put on here)
the error is "There is already an open DataReader associated with this Command which must be closed first."
which is odd because there sqlcommand used for reader2 is different.
Can I not use more than one reader at anyone time? I used to have loads of recordsets open in asp 3 no prob.

Apr 26, 2007MY Current database in SIMPLE recoverey model
I have set up the transactional replication. MY log reader process wakes up and runs every 5 min. Does my transactions will get deleted or they still in log file as active even it is in simple recover model.
Logreader how it reads the Transaction log files .? I observed today we are running some big reports. those reports uses INSERT INTO FROM <TABLE > this process showing in DBCC OPENTRAN
MY log reader keep on reading the log file.. it did not come out from that five min duration...
Can someone from the MS share the what /how exactly log reader works ( inside details)
I would like to add more details
The Log Reader Agent is scanning the transaction log for commands to be replicated. Approximately 30500000 log records have been scanned in pass # 3, 1696 of which were marked for replication, elapsed time -623164036 (ms).

Sqldata Reader Question
Jul 18, 2006Hi,
I am trying to creating an application using C# where I read data from a SQL server. In the database, I have two tables. One that has the Order info and other table has the item info for each of the rows in the Order table. In my application I am run a query and open up a datareader to read in the Order info. While OrderInfoDataReader is still open, I run another query to get the ItemInfo and open another data reader. Well, ADO.Net does not allow two datareader be open at the same time.
My question, what would be a way around to solve the issue? I would greatly appreciate your help.
Thanks,
Emon.

the error its throwing is this

Coexisting SQL Reader && UPDATE
Aug 17, 2007In my current application, I have an administration form that fills in labels and checked states via data entered into the database using a similar user input field. What the admin page does is it first lists all the record names in a listview, then on select, it fills in the form based on what the records contain. This means labels text change, and check states change based on the string "True" or "False". This was done using the SQL Reader command.
Within the same form, the read checkboxes are editable via the admin. When the admin edits the controls, he will click the update button at the bottom and the database will UPDATE .. WHERE UserName = (Scalar for ListBox1.SelectedValue)
I've used the exact same UPDATE command in my form for the user, except the only difference was @ the WHERE clause-- I had it updating based on a GUID. I know my SQL statement is correct, but it just won't update the data.
Is it possible that the READER, which starts (and closes) on pageload cannot coexist within the same form as the UPDATE code?
My code is incredibly long, so for the purposes of a short post I'm not including any bit of it-- but if you would like to see it, just let me know.

Jun 22, 2004We restored a database with replicated tables. Now, the Log Reader Agent will not run. This displays:

(Source: fsdpdcis (Data source); Error number: 18768)
---------------------------------------------------------------------------------------------------------------
The process could not set the last distributed transaction.
(Source: fsdpdcis-DPDDATA-1 (Agent); Error number: 22017)
I have reinitialized all subscriptions on the fsdpdcis server and run subscription validation (with no response). The data did re-load during the reinitialization but does not seem to be getting updated. This is driving me crazy and I am desperate. Any suggestions would be greatly appreciated. I have search MS knowledge base with no results and BOL has not been any help so far.
Thanks

Raw File Reader Utility?
Jan 5, 2007Does anyone happen to know if there is a raw file reader utility available? One of my processes drops a couple of interim raw files and I'd like to be able to look at the data in them in a columnar format without having to run a downstream data flow with a reader inserted.

Feb 29, 2008I have an extremely simple (couldn't be simpler) WML query that I'm trying to use to populate a variable, and no matter what I try, I keep getting:
Error: 0xC002F304 at WMI Data Reader Task, WMI Data Reader Task: An error occurred with the following error message: "Invalid query ".
Here is exactly how I have the connection manager and task set up:
WMI Connection Manager:
ServerName = "\localhost"
Namespace = "
ootcimv2"
UseWindowsAuth = True
WMI Data Reader Task:
WmiConnection = WMI Connection Manager
WqlQuerySourceType = Direct input
WqlQuerySource = "SELECT Name FROM CIM_Datafile WHERE Name = 'C: est.txt'"
OutputType = Property value
OverwriteDestination = Overwrite destination
DestinationType = Variable
Destination = User::WmiVariable
I've tried setting the WmiVariable to both String and Object data types. I've tested the WMI connection (both within SSIS and through a sample VBS script), and that works just fine.
Any ideas?
Thanks in advance.

Excel Reader Issues
Mar 14, 2006Hi,
I need to load data from excel files which will be provided by a number (around 100 monthly) of external suppliers, so we don't get 100% control over the files themselves.
What my solution involves is copying the excel file to a common name (e.g. supplierExcel.xls), turning this into a pipe delimited txt and then loading the txt. I had trouble switching files when trying to load directly from excel.
All these files should arrive in the same format of 36 fields and of course in the right order; there will be rejections if they fail.
I've come across a problem extracting the data from excel where I'm getting 'the value could not be converted because of a potential loss of data' on field 1. It only happens on excel files where there is a quote mark as the first character and I have loaded other files quite happily without the quotemark.
Has anyone seen this before? Is this a known issue and how can I get around it, without recourse to manually changing the individual files?
Thanks
