We have 4 Servers which have SQL SERVER 2012 and "AlwaysOn" have been enabled on all 4 servers:
Server1,Server2,Server3,Server4
Server1 is the Primary node and thr rest are secondaries. There is a Sync relation between Server1 and Server2 and also there is aSync relation between Server1 and Server3 & Server4.
Is it possible to setup log shipping from Server2 & Server3(secondaries) to two new servers?
Hi can anyone help with a step by step instructions on how to set up log shipping in a clustered envionment?
I aware that your need to set up a clutered share but am looking for as much details as possible.
Thank your for your help in advance.
Hi,
I currently have a 2000 Ent. production server and a stand by server ready for transaction log shipping.
Is it possible to setup transaction log shipping on a live environment without any interruptions?
I'm currently backing up the log every 1 hour, I'd like to increase to 15 minutes.
Any help would greatly be appreciated.
Thanks,

I have an A & B node set up and running. I now want to add a C NODE.
The catch is the C NODE is in a SQL Cluster Environment.
I am guessing I add the Virtual Name of the C node to the current Always ON Cluster?
I tried adding it...the error message says" the Virtual Node is really the A node and to add the A NODE"?
Setting up Transaction Replication in test environment. I am willing to bet that most of you take a production backup (if so, how, and using what?), restoring the database to your test environment, then running a snapshot to your subscriber and away you go.
But perhaps you take a backup of your publisher and subscriber, if so, how do you know there are no inconsistences because there were transactions sitting on the distributor?
What do you do if you have additional indexes on the subscriber for reporting, that are not on the publisher?
Here at work we are having issues with getting consistent databases set up with T Rep, missing rows, duplicate keys at subscriber etc. How to avoid these issues.
To set up AlwaysOn Feature on cluster environment how many VM's we would require.
We have already have 2 VM's for cluster but am not able to configure AlwaysOn.Â
I am embarking on a project to upgrade our SQL server environment. I'm curious for some opinions on the relative benefits of Log Shipping versus a Clustered environment and you have any experience that has helped form your opinion on the issue?
Thanks,
Marc
I have two SQL servers that I am trying to setup log shipping on. I am unable to get the restore of the initial database to work on the standby server. It gets a "unable to open file" error when trying to do the restore.
I have created a "syncaccount" user on both machines, and both have same password. I have used configuration manager to set the user/password for the agents on both servers.
I have given syncaccount admin access. I have added syncaccount to the shares on both servers.
Wy am I getting this error.
Does anyone else think it is VERY difficult to make this function work.
I have getting issues when i am creating listener for always On . Error shown as below
Can not bring the Windows server fail over cluster (WSFC) resources online. (Error Code 5942). The WSFC service may not be running or may not be accessible in its currents states, or the WSFC resources may not be in a state that could accept the request.

hi
I have this variable setting in C# in my self developement project works fine.
but when i implement it in actual project does not work.
/Set \package.Variables[User::ArchiveExcelFileConnectSt].Properties[Value];"" + xlspath + ""
when i test it in SQl query analyzer i need to replace // with / and works fine. but when i implement in c# it does not in my actual project. both have different Database.
Do i need to turn on some thing in my Actual Databas that my project points too or is there some thing else.
Thanks,

I was looking to change the file growth setting in our AlwaysOn environment databases.We have a single availability group, one primary and one secondary replica. I learned that when changing the file growth setting on the primary databases (data file), the change flows though to the database on the secondary replica.However after doing the same with the log files, the file growth setting changed on the primary but the change did NOT propagate to the secondary.
Is the solution to apply the change directly to the secondary?here's the T-SQL code I used:
ALTER DATABASE myDB
MODIFY FILE ( NAME = N'myDB_log', FILEGROWTH = 512MB );
GO

Hi all,
We're just in the middle of performing our first release of SSIS packages through various environments.
The way we are set up currently is the developer will check the package(s) and related config files out of source control, develop on their own machine and check everything in again. Then we deploy the packages consecutively to the Dev, Tst and Prd servers.
We are going down the path of using one environment variable for every config file. some packages share config files (e.g. we've only one config file for each database or ftp connection etc.) and some config files are package specific (error log file connections and success/failure e-mail sources etc.).
What we want ideally is a script that we can check into source control that will create the environment variables on a server at deployment. The "set" command at the command line can be used to change the value of an environment variable, or to create a session-specific variable, but not to create environment variables.
So far the only method that we're using is manually typing in the environment variable names via control panel and copying and pasting the paths into the value fields. Given that we're deploying potentially hundreds of config files, it's obvious that this new-fangled GUI point-and-click and copy-and-paste method of deployment is absolutely foolproof and totaly not prone to any error whatsoever.
Please tell me there's a way to create and set environment variables without going through control panel. running a script or something to do it automatically will: Ensure that each environment is set up accurately and identically, eliminating human error. Ensure that when a developer checks out a package to their local drive, although they may have to change the variable values, he can at least create the relevant variables without having to type them in. Enable efficient migration to another new server (for example during Disaster Recovery).
Can anyone point me to some example scripts at all?
Kind Regards,
Andrew.
Hi all,
Currently i faced a problem while setting up SQL 2005 STD into the Cluster Environment.
User has existing windows cluster purposely for Print Cluster usage.
We install SQL 2005 standard version into windows cluster.
After installed SQL 2005 cluster into windows cluster. All SQL services can be up correctly in Cluster.
Then we install Print Manager Plus software from vendor Softwareshelf.com into both cluster nodes.
Configure/add one additional resource as generic service with dependency with windows/system32/spooler.
Everything is working fine for that night.
Next day morning I install SQL 2005 Management Tools into both server.
User claim that one of the printers has 1 print queue cannot be deleted in Print Management software from Microsoft. We tried shutdown and unplug cable from that PC. That print queue also cannot be deleted.
That I check with Cluster Administration. Found Visual C++ runtime error. It is related with €œspoolsv.exe€?.
Existing environment: OS is windows 2003 Ent R2 SP2 x 2
Cluster has been setup for print management server.
Please help.
Thanks

I am able to enable the Trace Flag 1400 using DBCC TRACEON (1400) GO. Only then we can able to configure for the ENDPOINTS.
I successfully configured the ENDPOINTS for both the principal server and Mirror server .And then when I started the START MIRRORING.
I got the error message. Please find the Message below.
An error occured while starting mirroring.
additional Information:

If anyone have a solution on how to setup a database mirroring environment.Please send.
Hi all,
I need some advice on this scenario.
I have to set a Disaster Recovery (DR) server from my production Server( Most probably, i will be using Database Mirroring for my DR Server). Right now, the production is log shipped to another server for reporting every 15 minutes.
So, for setting up Database Mirroring onto my DR Server, i can take Full Backup from production without damaging log Shipping.
But, for setting up Database Mirroring, we need to restore most recent Transaction log backup with norecovery ( Correct me if i am wrong).
But, I cannot take log back because the prodcution database is log shipped for Reporting needs. If taken, log chain breaks.
Can anyone please suggest some work around for setting up the DR Server with minimal downtime.
Thanks for all your help.
I am trying to set up log shipping in a clustered server environment. I am pretty confused about the location of the shared folder to be created to put backup created by  log shipping job. Which drive should I use either local or clustered shared drive to store the backups in primary server and  to copy the same in secondary Server?

View 2 Replies View RelatedWe are looking to setup an AlwaysOn A/G between two SQL instances across two SQL clusters - one cluster has two nodes the other has three nodes.
Is this possible using WSFC? Does the A/G wizard just handle this?
I'm setting up my first pair of Sql 2012 servers using AlwaysOn. I set up backups to run on the primary and I understand that you can set up backups to run on both the primary and secondary servers but the secondary will fail. Is there a way I can stop the secondary server from sending out error messages about failed backups? Is it possible to script it so that the server looks at whether it's primary or secondary and turns on or off alerts based on that?
View 8 Replies View RelatedI am trying to build the 2 node 2 clusters with the AlwaysOn.
Here isthe landscape.
2 nodes PROD failover cluster (running once instance)
2 nodes DR failover cluster (running 2 instances - DR and PRE-PROD)
Both clusters are in different geographies.
PRE-PROD can be editable. So out of scope of Always On.
One instance on PROD -> DR of the other box. [Want to achive thru AlwaysON]
Now my Question:
1) Do i need to have all the 4 nodes in same failover cluster group? If yes, then this would become MultiSubnet cluster Or Is there any way those 2 diffrerent failover clusters (one DR and one PROD) can be part of AlwaysOn.
2) Can i use the clustered disks as in the above landscape for always on?
We have 2 SQL 2012 servers. Our application has 2 databases. We are creating an AlwaysOn cluster. Is it good to create 2 AlwaysOn clusters to have 1 database primary on one of the servers and the other database primary on the other server?
I have been asked if it is possible to have one database running on one server and the other database on the other server. Is this possible without creating 2 separate AlwaysOn clusters?
While configuring SQL Server 2012 Cluster with Always on, why do we need two secondary replicas.

View 1 Replies View RelatedI have four instances and each instance have its own Availability Group with its own listener.
Would like to know if you can have one listener for multiple Availability groups?
How many nodes can you have in a cluster with SQL 2012 alwaysOn.
I understand that availability groups are limited to 5 nodes but if you had a 10 node cluster and decided to create multiple availability groups using various nodes within the 10 nodes but never exceeding 5, is that possible?
Or is there a counter or some validation from SQL AlwaysOn that actually hard limits to a grand total of 5 nodes in a cluster?
We had 3 Availability Groups set up in SQL 2012 last year but they were poorly named so I am just looking to rename them but there doesn't seem to be any command for it that I can find.Can they not be renamed once created? I guess I could just create new ones and move the DB's into them but just thought I would check!
View 1 Replies View RelatedConsidering trying to move 2008 acitve/passive cluster with log ship to day old read only 2008 server to 2012 active/passive to 2012 AG Read only server. Only problem is that read only instance may have to be a 2nd instance on a server. The new box is a beast 64 core 256 gig of RAM hp so this is no dog. So I have these choices
migrate 2008 active/passive cluster to 2012 active passive (this will be it's own ordeal)take new monster box and build two instances, one that will run the AG read only database, the other will house reporitng services and analysis services and a few dw databases. We are not heavy into deep dive analysis services yet kind of in it's infancy. Not sure if this other instance will be sql 2008R2 , may be able to do 2012. MY also have a few small sharepoint databases but they barely use it.
In always on under availability group server name properties can see the option Readable Secondary. In that for secondary server the Readable Secondary Option is YES and for Primary it is Read-Intent. I believe Read-Intent allows only read only connections and YES allows all user connections.

What exactly it means for the primary and secondary?
I'm setting up AG replication over our WAN (1GB MPLS). Using sql stress, AG replication quickly falls behind. Network throughput plateaus at ~14Mbs.
The problem ISN'T NETWORK
using conventional mirroring, the same workload never falls behind, throughput plateaus at ~26Mbs.
it's almost like log stream compression isn't happening for AG...
both mirroring and AG are using async.
Can we make SQL 2012 Always ON over the normal SQL Cluster 2012.
View 3 Replies View RelatedI have setup SQL AlwaysOn between primary and DR data centers. Here is the setup:
Primary data center: Server1 (Primary), Server2 (Sync Commit Secondary), Server3 (ASync Commit Secondary)
DR data center: Server4 (ASync Commit Secondary)
Data synchronization and manual failover works fine. But, sometimes, the AlwaysOn cluster automatically fails over to Sync Commit Secondary on Primary data center. Here is the error message from Failover Cluster Manager->Cluster Events:
"Cluster has missed two consecutive heartbeats for the local endpoint xx.xx.xx.yy:~3343~ connected to remote endpoint xx.xx.xx.zz:~3343~"
"Cluster has lost the UDP connection from local endpoint xx.xx.xx.yy:~3343~ connected to remote endpoint xx.xx.xx.zz:~3343~"
I had our network engineer check all connections multiple times and he confirmed everything is fine. But he was also able to confirm (using monitoring tools) that right at the time of a failover, there is almost 2GB worth of traffic going from Primary Server to DR server. That happens every time. I had checked the times of all failovers and there is no job or process occuring that will produce 2GB worth of data. Also, this happens regardless of which server is primary.
Even though the failover works fine, this unexpected automatic failover due to missed heartbeats are occurring often (2-3 times a month).
Here is the list of errors from the Cluster Validation Report:
Under Network Section, I see the following error messages in Red:
Validate Network Communication
Network interfaces Server4 (DR) - SAN_Team and Server1 (Primary) - SAN_Team - VLAN 20 are on the same cluster network, yet address xx.xx.xx.pp is not reachable from xx.xx.xx.yy using UDP on port 3343.
Network interfaces Server4 (DR) - SAN_Team and Server2 (Secondary) - SAN_Team - VLAN 20 are on the same cluster network, yet address xx.xx.xx.qq is not reachable from xx.xx.xx.yy using UDP on port 3343.

So I have 2 servers S1 & S2.
Database Group 1 = L1 with Primary S1 and Secondary S2
Database Group 2 = L2 with Primary S2 and Secondary S1
For 99% of the time the 2 groups of databases are not related. For the 1 procedure that does move data from L1 to L2 something like
Update L2.DB.Owner.Table
set flag = 1
Whare a = 0
On S1 I have a linkedServer with connection to L2.
If I have a failover I cannot have L2 on S2 as they are essentially the same server.
How to I use the 2 groups hand in hand.
