Load Balancing And Fail Over For SQL Server.
Jun 7, 2005Hi!Currently we only have one SQL Server database in our production system. I would like to add one more SQL server 2000 database. I would like to configure them so that both server share the load and Failover. I did some research and I found that I can do this by installing the OS (Windows 2000 Server Enterprise Edition) and SQL 2000 Enterprise Edition on both machines using the windows clustering. I want both servers to be active. They both have a copy of the production data. What I don't know is that, if it is possible to synchronize the data on both databases using SQL Server Replication utitlites. From what I know one SQL Server must be Publisher and one Subscriber. Can one sql server be both? Because I want both sql server to be identical. Can I set up replication between more than 2 servers? We just need to add one server for now but I would like it to be expandable. In the future we may need more.So Please provide me some ideas and answers about the following.1- Can two SQL Server cross replicate (both update each other in order to be identical)?2 -Does replication work beyond 2 servers.?3- If you were to set up a production database; what do you recommend considering the load balancing and Failover using Windows 2000 Server Enterprise Edition and SQL Sever 20000 Enterprise Edition?Thanks,Michael

Nov 6, 2006i have a table with 10,000,000,000 records and i need Select and Insert many
records from or into this table in less than one second.
i can't buy a very expensive hardware(Server) for this SQL Server 2005
but i can buy many medium price hardwares(Servers) for this SQL Server
2005.
how can i distribute or cluster this table between many hardwares(Servers)?
note: i have few users (maximum 5 users) for my database but i have a
very large table and Sql server 2005 server need to respond to this
users in less than 1 second.
i want to distribute this huge table in seperated hardwares. becuase i
can't buy a very expensive hardware from my server but i can buy many
medium price hardware for my server.
note: i need this: when a user run a select query on this huge table
his/her request distribute between many hardwares not one hardware.
[Q]SQL Server 2000 Cluster Load Balancing
Nov 8, 2001Hey guys,
Lately we have come across a problem where our application is undergoing some extreme load against the SQL 2000 server database we have setup, where the server is hitting 100% CPU utilization each time. Currently the box is a 2 processor box.
Here is the question I have. I have seen under most SQL Server clusters that an active/passive setup is implemented. Where the passive server just exists as a failover mechanism. What I am looking for is some information on how to setup active/active setup where each server receives processes to handle.
Has anyone created a setup like this? Are there any standard benchmarking tools that can be used to see how this configuration increases performance? Is this setup more favorable than going to a 4 processor server as oppossed to our current 2 processor server?
BTW: We have noticed that after a web application where the user sits idle for a while the SQL Server application loses the connection with the application user...Is this the SQL Timeout causing the connection to disconnect?
Thanx for any response...

SQL 2012 :: Cluster Errors - No Auto Fail Over?
Jun 25, 2014My environment is a 64 bit Windows Server 2012 Standard edition that is running SQL Server 2012 SP1 Standard Edition (64 bit) which has an Active Passive Cluster set up and I unfortunately had no involvement in this cluster build. The person who did is no longer with the company and is not responsive to questions.
This morning this following errors popped up:
Event ID: 1230 - Cluster resource 'Databases' (resource type 'Physical Disk', DLL 'clusres.dll') did not respond to a request in a timely fashion. Cluster health detection will attempt to automatically recover by terminating the Resource Hosting Subsystem (RHS) process running this resource. This may affect other resources hosted in the same RHS process. The resources will then be restarted.
The suspect resource 'Databases' will be marked to run in an isolated RHS process to avoid impacting multiple resources in the event that this resource failure occurs again. Please ensure services, applications, or underlying infrastructure (such as storage or networking) associated with the suspect resource is functioning properly.
Event ID: 1146 - The cluster Resource Hosting Subsystem (RHS) stopped unexpectedly. An attempt will be made to restart it. This is usually associated with recovery of a crashed or deadlocked resource. Please determine which resource and resource DLL is causing the issue and verify it is functioning properly.
When I saw these errors, I brought the "Databases", "Logs", and "Quorom" disks back online and all was well. I then proceeded to check Application and System Logs noticing there where some VMWare/SAN errors that caused the CPU spike resulting in the Cluster errors.
Regarding the questions, why didn't a failover occur and What can I do to mitigate this process are now what I am focusing on. Researching the above errors, I discovered that you could a policy based what happens in a situation like occurred this morning. You can set policies at the Role level, "Server" level, and at the disk level.
The Role Policy seems to be a little less involved, screenshot RoleProperties.png show these. I assume these are defaults. The server name properties are set to the following screenshot, Servername_Properties_Policy.png. This seems to be correct to me, but there is where I am lacking. I think this means that if it fails at this level all associated resources, disks, etc will failover to node 2.Now where I think the issue is, the third screenshot, Database_Properties_Policy.png. There is no policy set to for situation where a disk resource fails. Which I believe is what happened this morning. Some questions:
1. Do I need to set this similar to what is in the ServerName screenshot?
2. What happens if I check the box for "If restart is unsuccessful, fail over all resources in the role"? Will this only fail over this one disk? If so, it doesn't seem like that would be ideal. Would it fail over at the Role level and move over all associated resources?
I am also not sure what time limits I should set for Period restarts, maximum restarts, delay between restarts, etc...

Load Balancing In SQL 7.0
Dec 14, 1999Hi All,
We have a Intranet Application which uses IIS / SQL Server 7.0, we are trying to support the application for 30,000 + users.
Since SQL Server can only support upto 32676 user connections (Theoretically), is it possible achieve this with clustering / dynamic load balancing. Does MSCS and SQL 7.0 support this. Any other ideas, 3rd party software etc?????
Any input will be of great help.
Thanks

Configuration/load Balancing
Jan 25, 2006HiOn our SQl Server (2000) we can have queries that take at least 10-20mins(require full table scan fo billion row table). When one of these queriesis running it substantailly slows down very quick queries (sub secondqueries take several seconds).I believe there is no way to set priorities but was wondering if thereare other configuration settings that could help. The server is dualprocessor so maybe setting maxdop to 1 will help. Memory size isdynmaically assigned up to 4Gb but as the DB size is > 1Tb I'm not sureif allowing this much memory is actually decreasing performance when thequick query trys to get through.Any suggestions.ThanksMike

Query Load Balancing
Apr 10, 2006Hi,
We have a massive database that users run complex queries on. The queries are never the same so caching cannot be used too much effect. When many queries are run at one time by the various users the system slows down.
What we are trying to achieve is maybe have a primary SQL Server 2005 machine and multiple (4-5) SQL Server 2005 secondary machines. The primary machine would get the query and would decide based on loads as to which secondary machine would fulfill the query.
We are not worried about failover and clustering and all that fun stuff. Our primary concern is to achieve the quickest execution of the query. We were wondering if SQL Server 2005 has any feature that enables query load balancing of some kind.
Thanks
DB Mirroring + Load Balancing
Nov 3, 2006Is it compatible to set up SQL DB mirroring on 2
different physical servers (High availbility + FULL transaction safety +
Automatic failover with a third server as witness) and simultaneously set up
network load balancing between these 2 servers (option with Windows Server 2003
Enterprise) ?
If yes, which type of licenses do I need and how
many (for SQL server 2005 and Windows Server 2003) with such a configuration
?
- 4 physical servers in total : A, B, C and
D
- load balancing between A and B (same application)
- load balancing between C and D (same application)
- A hosts principal DB X, B hosts mirror of DB
X
- C hosts principal DB Y, D hosts mirror of DB
Y
- D is witness for A and B
- B is witness for C and D
- A and B : only internal clients <
25
- C and D : both internal and external clients
(internal clients <25, number of external clients is unknown (>25)
)
Hoping this description will be helpful enough for
you...
(I am looking for a very high availability
system)
Thank you in advance for your support.
This licensing question is pretty much urgent (for
a bid) : a quick answer would be very appreciated...
Load Balancing Or Seperate Databases
Oct 15, 2007We are looking at expanding our web application (C# and Sql Server). The module we are going to be adding will be far more processor intense (plotting and modeling) than any of the current code.
I need to know what the best design for this add on would be.
Would it be better to
a) Keep the new module as part of the core db (entire application on 1 database) and use loading balncing between 2 (or more) servers to handle the huge increase in demand?
b) Create the new module as a seperate database that runs on a seperate server?
If B is the best option (I am thinking it is not) is there a way to write easy and efficient queries and views of the 2 databases as 1.
Thanks

Load Balancing Using Service Broker
Jun 29, 2006I am trying to achieve load balancing through service broker.
I have a 3 server setup:
server1:
Source Database where the requests are sent. This has two routes created on this to server 2 and 3 with the service broker instance id specified. The service broker matches both these routes to the destination databases on Server 2 & 3 and send the requests in a round robin fashion by itself.
server2 & 3: These servers have the destination databases. The databases are exactly same with same messages, contracts, queues, services, and servicing programs. These don't send the responce back and the source is also not expecting for any response from the target databases.
When I tested this scenario it was behaving in a different manner. If there are 20 requests, in a normal case 10 requests should go to either of the destiantion servers, but I found that sometimes it was 11-9 or 12-8 only once did it do a 10-10.
Also I want to know is it best practice to rely on the inbuilt feature of the service broker in matching the routes and sending the messages rather than doing it ourselves. I which case one has to write the logic for sending the message to appropriate target server based on the status of the destination queue.
I also want to know which would be the best technique to use to bring the two destination databases in a concurrent state.
thanks

SQL Failover - Mirroring, Log Shipping, Clustering, Load Balancing
Jun 14, 2007
Hello.
I am confuse and cant decide on how to setup high availability on our SQL 2005. Here's what on my mind and on resources list:
I plan to have mirroring on my SQL1 to SQL2 with the help of SQL3 as witness. So this would be automatic failover. My idea on mirroring is when SQL1 goes down, SQL3 would tell SQL2 to run and be the primary. It will automatically failover to SQL2. Right? My questions are:
1) How can I revert back to SQL1 once it is ready?
2) I read in one of the post that it is impossible to write in a mirrored DB, is this true? I mean, what's the use of failing over to the next node when it's not possible to write and update data/records?
3) If number 2 is false (i hope so), how would the data be synchronize from SQL2 back to SQL1. Those transaction that were made while SQL1 is down.
4) How about the connection string from the web applications? Would it be automatically point to SQL2? We have load balancing setup in place, would this help web application connection to automatically point to SQL2?
Another setup:
We have SAN in place (not yet used, but is planning to use for this SQL thing), EMC to be specific. My question would be:
1) For SAN setup, the data storage would be centralize. So would that mean that SQL1 and SQL2 services will use the same data and log file from the SAN storage?
2) How would you call this setup then? Can this be clustering type of high availability? Will clustering work under load balancing setup? I believe mirroring is not possible here? Right?
3) How can I setup my 3 SQL servers with the same theory in mind: when SQL1 goes down, SQL2 will take over. Data will be synchronize when SQL1 is up and running again. With automatic failover and reverting back to primary.
I read so much topics about this, but the more I research, the more I get confuse.
Any suggestions, comments, advice is greatly appreciated!
Mirroring, Snapshot Replication, Load Balancing And Other BIG Questions
Mar 22, 2006You will all have to excuse my ignorance. I'm a developer who also doubles up as a development DBA. I am however not particularly knowedgeable about all the really important DBA stuff.
We've built a small BI solution using SQL Server 2000. Our problem is that our server is getting on in years (5) and doesn't really have enough disk space or grunt. We havce a number of summary cubes that we've optimised quite successfully but our billing line level cubes run to 60 million rows and, well, they're about as quick as a dead ferret. Especially given the stupid queries our data analysts keep running.
We have however proved our point. That this can be done and indeed SQL Server can do it. So we're now looking at some infrastructure spend and some new copies of SQL2005.
But i need some advice. Our user base is climbing through the roof, we originally had 10, now we have closer to 50 and at this rate it'll be a couple of hundred by the end of the year. We're using a plugin called XLCubed to deliver that data into Excel from the Analysis Server.
The OLTP database that sits behind it is fairly robust but we have a number of web based apps (mostly lookup systems) that want to use the nice shiny new accurate tables of data we have created.
So I'm looking at a fairly big server to hold the OLTP DB, this will also serve up live data to our web apps. Its worth pointing out that the source data system is a batch system that processes overnight so we load data from yesterday at 6pm each evening and process our cubes and stuff overnight. Thus the data is a couple of days out of date. Don't laugh they used to use MS Access and got one mangy data set a month so this is a massive leap forward.
I wanted to mirror the DB to another machine but I also want to have a separate Cube Server. I wondered if the cube server could use the mirror to read its data from as opposed to loading the Main Server (the mirror would be an identical box) we would also have a separate box running some of our other systems acting as the witness.
I also wonderd about exporting the Cubes onto file shares for use locally as opposed to via the server which is how they connect now.
We have been using Reporting Services and some of the queries the devs write are not exactly efficient. So I was also planning on clustering a pair of smaller servers into a reporting farm. Could I use another SQL Server to serve data up to them? Could I use a DB snapshot to copy the data required to this server? What are the time / size implications of using a snapshot and replicating it over each night?
Any suggestions for places to read up on this? I've looked at the MS marketing blurb and while its big on buzzwords its light on specifics. Like how it actually works and how you would actually configure it to do some of this and what the implications would be.
Any advice?
many thanks

SQL Server Admin 2014 :: Load Balancing With Availability Groups
Aug 28, 2014We are having a conversation at work and the subject of load balancing with SQL came up. Right now we are running SQL Server 2014 on four (4) machines. I am using a AlwaysOn with Availability Groups (AG). Now I know that we can scale out the reading in AG by allowing the secondary serves to receive reads.
Is there a way to be able to do this with writes? Can I have in essences 2 masters that some how reconcile with each other? We are expecting a huge amount of writes in the near future and we need a way for SQL to handle the amount of traffic we are expecting with out any issues.
I explored the possibility of Peer - to - Peer replication; however, it seems that it would be more work if we are constantly making updates to the database scheme.
Microsoft OLE DB Provider For SQL Server Error '80004005' On Load Balancing
Jul 7, 2007
I have posted this also in one forum. Somebody might have idea here.
We have four Windows 2003 advance servers with SP 3 configured on NLB.
Each of them has one NIC.
Recently we started to get frequent time-out error messages from web applications on those servers when they try to establish the connection with the SQL 2005. If you run web pages application to connect to sql server 10 times, 9 times you will get good connection results and 1 time you will get time-out.
Microsoft OLE DB Provider for SQL Server error '80004005'
Timeout expired
/common/mypage.asp, line 20
Connection to sql server is established with the connection string. Any idea how to solve this problem? Is there a connectionproblem? from NLB to Web to SQL?
We have tried doing some suggestions (e.g. LMHOST, IP, domain account for WEb to SQL connection, the Query Wait in SQL advance property.), but seems this timeout expired still exist
Thanks in advance...

SQL Agent Mail Profile On Cluster Fail Over

View 3 Replies View RelatedSQL Server 2005 Fail Installation On Cluster
Sep 27, 2007
Hi,
A few months ago, I was trying to install SQL Server 2005 SP2 on a cluster (Active-Active), the Cluster has 3 instances, 2 lives in one node and the other one in the other node. When I try to make the deployment an error message appear, I do not have the error right now but it€™s something like €œCould not connect to the passive node, installation failed€?. The worst part of the error was all instances shut down and I couldn€™t bring on line and I have to reinstall all instances. I need to install SP2 but I€™m a little afraid fail again. Do you know the best way to deploy the SP2 on a cluster? Maybe move all instances in one node before install SP2? Can you help me with your comments. Do you think I have problems with the windows cluster?
Thanks and Regards,
Recovery :: AlwaysOn Cluster Did Not Fail Over Successfully
Aug 14, 2015I have had a serious issue with a production AlwaysOn cluster whereby the service did not successfully transition to the secondary node and I cannot find the root cause of the issue.
Some details: It is a 2 node cluster (same datacenter) with a shared disk quorum, Windows Server 2012, both are virtual machines running on VMWare vSphere  5.5. SQL Server version is 2012 Enterprise SP2 CU6
The failover occurred because of a network incident (a spanning tree recalculation caused a connection timeout between both nodes). Initial entries in the SQL Log look normal for this event, for example:
05/08/2015 11:18:06:Â A connection timeout has occurred on a previously established connection to availability replica 'FIN-IE-PA078' with id [6910F4A9-87E7-4836-BA79-0F41BE90266D]. Â Either a networking or a firewall issue exists or the availability replica has transitioned to the resolving role.
05/08/2015 11:18:06:Â AlwaysOn Availability Groups connection with secondary database terminated for primary database 'UserManagement' on the availability replica with Replica ID: {6910f4a9-87e7-4836-ba79-0f41be90266d}. This is an informational message only. No user action is required.
[code]....
My interpretation of this is that the cluster failover attempts failed, because the network condition still persisted. The network interruption lasted approximately 2 minutes, and I would have expected the cluster to come back online at this point, after the restart delay period as suggested in the last entry in the error log. However this did not happen.
MQPERF.dll Performance Counters Fail To Load (was New Member ... With New Problem)
May 2, 2006Hello to all the members.
I have a SQl server on a Win2000 box. The server is located behind a screened subnet, and has no access to the outside world except for 1433 and 445 inbound from a webserver located in a DMZ, forward of the internal firewall. Rules are very tight, and the IIS box is patched and has been hardened further including running urlscan. (allowed verbs=get,head,post. all executable and script types disallowed, permissions very tight) I have written an appication that monitors bad http requests in real time to check that the URL scan is working, and it seems to be. The only way to get to the SQL box, would be running injection on page code (majority written by myself no raw sql) on the web server or launching an exploit over HTTP against known ADODB flaws on the web server. The SQL server is a domain member, the IIS server is a standalone. If theres a way to compromise the SQL box without first breaching both firewalls, or first compromising the IIS server, I dont know how to do it. Still, the sql box began acting up, refusing to accept a terminal services connection (the error stated that there was a failure to load Win32.sys) No sign that the machine had been compromised. I restored from a complete back up, which seemed to fix the terminal services problem, but now the sql performance counters fail to load. Specifically MQPERF.dll. Any ideas on what may have caused the server to have 'issues' (prevailing theory centers around evil spirits), and what can I do to get the performance counters to load. Tried replacing the library.
Thanks in advance,
VLG
SQL 2012 :: Advanced Cluster Preparation For New Instance On Existing Cluster
Apr 10, 2014I 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?
SQL 2012 :: Server Cluster Without Windows Failover Cluster
Feb 18, 2014I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?
