SQL 2000 Replication Agents Connecting To Local Host Multiple Times?
Aug 21, 2007
Hi all
I have SQL 2000 SP4 running on a W2K server SP4.
The server acts as a subcriber and publisher and acts as its own distributor.
Each publication uses its own distribution agent and is set to loop.
There are 4 queued updating subscriptions on this box.
When running 3rd party tools to determine open active ports, the replication executables (distrib and logreader) are connecting to local server multiple times. Easily 15+ established connections plus many more waits.
Everything connects to 1433 then opens a new port.
Is this because of the queued updating?
Replication is functioning as it should without any problems.
I even checked our 2 main distribution servers which only act as distributors and there is not one connection from replication to itself.
Can I have multiple SQL Server Agents running concurrently?
I would like to have 10 instances of database running on my local SQL Server - each of these are Merge Replication to a unique database located offsite.
Do they all run through one SQL Server Agent?
If they do would this be a slow process as, I think, the SQL Server Agent queues the replications pending.
During an upgrade, we had problems with PK errors on sp_MSget_repl_commands. I recreated the SP with the varbinary characteristic as we have seen in many posts and it was sucessful in starting. However, the sp now appears as a 'user' sp, not a 'system' sp, however I an not sure that is a real issue.
The problem I am seeing is that none of the agents are appearing in replication monitor under their agent folders. Replication appears to be working fine and the publications are showing on the distributor in the Replication Monitor - Publication folder under the appropriate publisher. But all of the agent specific folders (i.e. Snapshot agent, distribution agent, etc) are empty.
Another interesting point, is that if replication fails, the failure 'X' shows up on the Agents folder as well as the publisher, but again, no sign of the agent in the folder.
I'm creating an app and have SQL Server 2005 Express installed. Most of the hosts now offering SQL Server 2005 are a bit pricey compared to those only offering 2000. Will I have any difficulty uploading my site and running the db on SQL 2000? Thanks in advance.
I have database on localhost and i want to show this data on my website. I want to create a database online and want to sync with Local Host. Can it be possible syncing data automatically after some interval?
Is it possible to obtain the status, running or not running, of the distribution agents that appear under Replication MonitorAgentsDistribution Agents in Enterprise Manager using WMI? If yes, can you please tell me the WMI namespace and objects that can be used?
I have created transactional replication on my servers (production server and backup server) and created pull subscription at the backup server. On my production server that also is a distributor and publisher there exist two agents, Snapshot agent and Log reader in the Publishers folder under replication Monitor.
There are also another agent with the backup server name and database name: BackServ:DBName having the type Pull and 'No replicated transactions are available' as Last Action. My question is: What is this? Must it be there?
I have encountered some problems in scheduling the replication agents but before explaining that let me give a small background of the current DB landscape.
It is implemented as Star topology or re-publisher topology with the publisher and the subscriber configured on SQL Server 2000 and it consists of ShareDB on SQL Server 2005 which acts as the re-publisher of data. All other databases publish articles to ShareDB which in turn re-publishes to the databases which subscribes for the article. The topology is using a remote distributor on SQL Server 2005 to offload the replication agent jobs processing from the OLTP environment. The distributor job agent is running continuously and it is shared for a specific database in case of Snapshot replication. And all the Transactional publications will have a separate distributor agent. At present the replications agents are scheduled on both the publisher and ShareDB.
Now, I am trying to enforce one way scheduling on the publisher side which will start the snapshot agent for the corresponding publication on ShareDB after the distributor agent transfers the data from the snapshot folder to the subscribers. This approach is effective and more reliable in the sense that data synchronization will happen immediately after the distributor agent transfers the data to ShareDB.
The following are the issues related to scheduling the replication agent on the publisher only.
1. I have included sp_start_job stored procedure after the run agent step in the shared distributor job agent steps to start the snapshot agent of the corresponding publication on ShareDB after the distributor agent transfers the data to ShareDB. Since the distributor agent is running continuously in our scenario, the next step is not getting executed and so the job agent of the corresponding publication on ShareDB is not started.
2. It is also necessary to specify either the job name or the job id in sp_start_job stored procedure to start the job agent. With the replication setup configured in the aforementioned fashion, how is it possible to invoke the snapshot job agent of the corresponding publication on the second link (from ShareDB) dynamically after the distributor agent on the first link is completed?

I have a page that connects to SQL server. It works fine when running in local host but when I publish to the server, I get the following: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Any ideas on where to start? Thanks,Mark
I have 5 laptops, 1 laptop with SQL Server 2000 and the other 4 with SQL Server MSDE Rel A. I had a "Merge Replication" scheme that I had to set up. The laptop with 2000 will be the main Publisher/distributor and publishes/merges to two of the MSDE laptops(these laptops have pull subscriptions that pull from the 2000 laptop). These 2 MSDE laptops in turn Re-publish their data to the last 2 laptops and my scheme ends there. I have succesfully been able to Script this entire "Merge Replication" scheme, and I ran it. It creates all Components needed for my scheme to work.
1 issue though. It doesnt kick start the agents :eek: , so the replication scheme is just dormant.
Does anyone have any examples of scripts that I could use to kick off all the agents (snapshot,merge agents etc) and maybe to stop them too. I seriously need this, because we will need to have the entire process scripted.
Thanks

p.s. Also does anyone have sample scripts to alter settings for the SQL SERVER AGENT, for example altering its "Log On" parameter to allow a particular user with Admin privileges and also to switch its start mode to "Automatic"
I have a application which uses the automatic asp.net membership stuff to make it work. (In app_data). It works fine on local host, but when I use it on the web server I get the error message (after clicking the log in button):An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Please help me fix this. Thank you for your help,Sam
hi my local host cannot open the connection to my database, whilst testing with vwd seems to be able to do this? other server side functions work (response.write("hello world")) in my iis the version of .net it says its running reads: 2.0.50727, though when i go to add / remove programmes i have 3.5 there? maybe its nothing to do with .net versions? thanks in advance for your help pete
VPC is configured to use the wireless card on the host. Firewalls on both systems are completely disabled. Machines can ping each other. Both machines can access the Internet. I can browse the SQL Reporting Services Web Site on the Host from the Guest. Host SQL Install has remote connections enabled. If I browse for Network server from teh connect dialog on teh Guest, it finds the Host.
Why can't I connect to the Databse Engine on the Host from the Guest? I have tried both TCP/IP and Named Pipes and both show a connection failure. (Not a login failure)
If it matters, the Guest OS also has a SQL Database Engine running. But I don't know why that would stop me from connecting to a remote instance.
This is the most frustrating error I've ever encountered.
I can get no more info from sql server besides "server execution failed". It gives this error when starting the snapshot, distribution, and log reader agents.
This server has been working in this configuration for over a year. We made no changes except restarted the server. This is a windows 2003 server with sql server 2000 running all the latest patches and windows updates.
I get the error message: Queue reader aborting. The steps failed...in queue reader agents of SQL 2000 replication. Could any one give me a hint of how to troubleshoot this problem? Thanks a lot in advance.
i created a layout in visual studio 2005 with the proper dimensions to print on an Avery 5160 label sheet (3 labels across and 10 down)
in the Body properties, i set Columns to 3, ColumnSpacing to 0.125", and Size 2.625" (W) & 1" (H).
i created a list table with a text box of the same dimension as the Size in the Body.
the thing is when i go to preview the report in visual studio, it just shows all the data but only in one column, but if i click the Print Layout button, it shows all 3 columns, then when i print it, it works! so i assumed that this was just the way visual studio handled the data. no big deal...
the problem is when i upload this to the reporting services on our local intranet and run it from the reporting services, it shows only one column (the left most only) and prints that way too; it's almost like i need a Print Layout button on the reporting services (which there isn't one).
is there something that i need to set so that it will print in 3-column form from the reporting services so people can print on label sheets?
i hope this makes sense. also, i tested this on the same printer just to make sure it wasn't hardware.
I have a transactional replication set up from one server to another. From last couple of days i am noticing two distribution agents running for the same subscription in the replication monitor. Before this only one distribution agent was running. Is there any problem having two distribution agents running in parallel for the same subscription on a server?
I'm using sqlexpress 2005 with asp.net 2 and all things work in my computer good
but when i upload it on the internet in my host it return this error :

I am using sql server locally and i'm not using it remotly
i just created a simple page (just have a detailsview) and upload it to the internet
and then upload my mdf and ldf files to the app_data folder
I have an ASP.NET application that runs under the development server. Before deploying to my host I wanted to test it under IIS. I set up a virtual directory under IIS, but when I try to open the home page I get an error Unable to open the physical file "E:CDiskLocalWebSitesDIWSchedulingApp_DataDIWDB.MDF". Operating system error 5: "5(Access is denied.)".and a code dump showing that the code is breaking at the open connection. A little research on the error indicates that IIS does not have permission to execute the database operation. I can not find any information on how to give IIS this permission in SQL Server 2005 Express. Any guidance would be appreciated.
I am trying to query the Topics in my discussion forum...The Topic contains a "last_poster_id" and a "author_id" I need the username and userid for both "last_poster_id" and "author_id" in the table "aspnet_Users"How do I do this?I would guess I need to use sub select statements. Can someone help me?
I installed SQL reporting services 2005 and successfully configured reporting services.After designing the report using Bussiness Intelligence Studio, i tried to deploy my reporting services application to the localhost , I got the below mentioned error :

Is it possible to host more than one site on the server that hosts reporting services?We have a web app that is accessed through intranet. This site is hosted (IIS)on the same server as the sql server 2005 database that is used as the backend. Is it possible to run reporting services from this same server? or does the reporting services default site require to be the only site hosted?

Hi all. Im using Visual Web developer 2005 and have successfully connected my SQL Server to Visual Web developer website. When i run it locally, its fine. But, i now would like the site to be placed on the net - but im not sure how to connect it properly in the webhost. Can someone tell me how this is done please, or a link? cheers.
I have a situation where I run the same taks multiple times during the execution. I would like to have one task which runs every time, instead of duplicating the task over and over 14 times in my script.
Basically, it is an audit log, which I set variables and then insert into a SQL table the variables.
I would like to do this:
Task1 ------Success-----> Set Vars -----Success--> Log | Task2 ------Success-----> Set Vars -----Success-| (do the Log task again) | Task3 -------Success-----> Set Vars -----Success-| (do the Log task again) | etc
This works, however, I have to duplicate Log over and over and over. No OR does not work, because it still only executes the Log task once.
Another option I thought of, but cannot find a way to implement is: Make the Log task "disabled" with no dependencies, then in the Set Vars script, enable and execute Log and disable again.
After doing some research it seems like you can only push the same table once using rda.push -- is this correct? If yes, are there any other alternatives for saving changes to the table back to SQL Server aside from merge replication?
One idea I am toying with is to pull the tracked table with 0 records, save changes to the tracked table, push, drop table and pull, repeating this process everytime I push the data. Wondering is somebody has any advice?
I have the developer edition of Visual Studio 2005. After successfully installing it in my local machine, I wanted to create a small application which connects to a database. I accessed the Server Explorer tool, right clicked on Data Connections and brought up the Create New SQL Server Database option.
The issue now is that I don't see a list of servers in the "Server Name" drop down box although in the Server Explorer itself, I have a server listed (your-c6b5e4eabc - The default computer name of my local machine).
I am given to believe that SQL server is unable to make a connection because I have not configured something which is essential.
I hope someone can point me as to how to make databases using SQL server and connect them to the application the way developers usually do. I'm a complete novice to VS 2005, and the SQL server configuration options have got me confused.
I'm not sure if this will help, but I'll include this here anyway :
When I tried copying and pasting the server name (your-c6b5e4eabc) into the "Server Name" drop down box and creating a database by entering a name in the "Enter database name" textbox, I get the following error message -
An error occured while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings, SQL server does not allow remote connections. provider : Named Pipes Provider error : 40 Error : Could not open a connection to SQL Server.
I'm running Windows XP Media Center Edition v2002 SP 2.
I just want to be able to create and work with databases from within the applications I create in Visual Studio 2005. I played around with the configuration options (like enabling some protocols, the SQL server browser etc., but to no avail.) Is there a way to revert back to the default settings in an easy way? Thanks in advance for all your guidance...
I'm totally a newbie here. I just installed everything on my PC. When I tried to connect to the local server(on my computer), I got this error. I guess I'm totally lost at the message of the red characters since all I try to do is to connect to the local server. CORPLLIDA1 is the name of my computer. Can anyone help me here? Thanks in advance.

Apologies if this is a dumb question, but I'm tearing my hair out over the basics when I should be spending time learning ASP.NET 2.0 and C#. I've searched the archives and a lot of people seem to be getting the same error as me, but when trying to connect from remote machines.
I'm getting what seems to be a standard message ...

When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I'm not trying to connect remotely, I'm on my developer machine. The error comes up when trying to connect from within VS2005 (Tools, Connect to Database). It also comes up if I create a new web-site and go to the ASP.NET configuration tool (this is, I guess, trying to create the necessary database behind the scenes but is unable to connect to the database).
I suspect the error might be related to one or more of the following ...
September last year I installed VS2005 Express and SQL*SERVER Express. Both were fully un-installed when I bought VS2005 Professional before installing the new product. When I set up SQL*SERVER 2005 Developer I remember choosing an option to have a separate user on my PC with administrative rights. Actually I don't recall much about what I chose but I can't find out where those permissions are managed from. I've followed various instructions to check that remote access is enabled (despite the fact that I'm local, not remote). TCP and Named Pipes are both enabled (and I stopped then restarted SQL Server). I've checked that the service is started. The odd thing is that I have had an application connect with the following string ...
SSLCon = new SqlConnection(@"Server=(local)SSLMJ;Integrated Security = True;" + "Database=SSLTESTRESULTS");
Though the application connection seems to work ok, I think I'm missing out lots of developer functionality because I can't get VS2005 to see the database or server.
