SQL 2012 :: Clustered Instances And Security
Jan 5, 2015
Is it possible for a clustered instance of SQL2012 to have 2 network names ?
Reason: I need to segregate admin access to a clustered instance so that the admins and SSMS connect via a different IP address than the application. I know I can block SSMS access via application-level firewalls, but ideally the application would connect to CLUSTER1INSTANCE01 on , say, 10.192.5.5, and the admins would connect to CLUSTER1ADMININSTANCE01 on 172.168.2.2, and they'd be the same instance, just using different names and IPs

My ambition is to run ASPStateInMemory with durability on, supplementing the in-memory database with an on-disk version to give session state persistence when and if the clustered instance of SQL runs into, say a network card failure and needs to fail to a partner node. I understand that DAG's are usually run between standalone instances of SQL running on different machines. But, can I combine the DAG with the FCI? Instead of using a remote standalone SQL server, can I just another instance in the same cluster?

Hi,
I have a clustered environment which has many instances in it. I have modified the xml file to allow several instances to use ssis. Everything works great when the instances are on the same node as the clustered ssis. However if they are on different nodes there seems to be an aunthentication problem and it loses my credentials. For some reason it tries to use Anonymous Logon instead. Here is the full error:
The SQL server specified in SSIS service configuration is not present or is not available. This might occur when there is no default instance of SQL Server on the computer. For more information, see the topic "Configuring the Integration Services Service" in Server 2005 Books Online.
Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. (MsDtsSrvr)
I would appreciate anyones help on this problem.
Thanks,
Adam

We have 2 clustered SQL instances (2 physical servers in each cluster). Instance2 needs to be setup as a linked server on Instance1.
At this time port 1433 between them is not open. I am referring to the port on the network switch, not in the Windows Firewall (ports in Windows Firewall are already open).
Is opening the port between virtual IP-s sufficient? Or does port need to be open between all physical source/destination IP-s as well?

I am setting up a two active instances of MS SQL Server on a clustered box. In the past I have set up using the nomenclature SQLCLUSTERNAMEINSTANCE-NAME such as SQLCLUS1INST1 and SQLCLUS2INST2.
But, this time the client will like it installed such as SQLCLUS1INST1 and SQLCLUS1INST2. I did not think this is possible --- That is I assumed that cluster resource names have to be unique. But, nevertheless I have tried to do so for the last few days, but no luck.
Can someone please let me know if it is indeed possible to have two separate instances in a single cluster.
BTW, I know this is quite possible with non-clustered instances --- where the SQLSERV1INST1 refers to an actual server name, and not a resource name.

When restoring DBs to other environments the SIDS don't transfer causing access problems, and when I use a SID scripting method and deploy on the target environment SQL says the login already exists.
I usually end up with the cumbersome process of explicitly removing the logins and re-applying - how to other DBA's get round this?

I am in the process of evaluating the use of Service broker for messaging in a load balanced configuration, and am not having any success. My configuration is as follows. 1) Master database on Box #1 which is the initiator of all dialogs 2) Target database on Box #2 3) Target database on Box #3 One of my goals is that the databases on Box #2 and #3 are as close to identical as possible. My routing table on Box #1 looks something like the following Name remote_service_name broker_instance address TargetOne TargetService
E96DC67E-F696-4D93-8545-C2E92157E32D tcp://server1:4022/ TargetTwo TargetService
56607120-26AA-4AAA-B9E4-F14689C40E41 tcp://server2:4022/ My messaging process begins with a dialog initiated from the master database (Box #1) to each of the target services. At this time, only the first server "tcp://server1:4022/" is receiving messages. The sys.transmission_queue shows a message outbound to "tcp://server2:4022/" with a blank status. I believe that my delivery problem has something to do with the resolution of the dialog certificate need for the conversation. The MSDN documentation states that: "Service Broker uses a remote service binding to locate the certificate to use for a new conversation...The certificate for user_name must correspond to the certificate for a user in the database that hosts the remote service." I am confused as to how I would configure remote service binding if one can not create more than one binding for the same remote_service_name. The following throws an exception on the last creation of the binding.
---CODE SNIP---
CREATE CERTIFICATE UFEDlgCertTargetPublic

Hello,
Not sure if this question belongs here in the Setup & Upgrade section but here is the problem.
When installing replication in a non clustered environment, the Sql replication jobs run fine with the windows login provided (this login has access to the snapshot folder and has the proper roles. All the log reader, distributer and subscriber agents work fine)
When installing replication in a windows (MS) clustered environment, the agents running under the same login and same privilages dont work. It seems like there is something wrong with the proxy account and the ability of sql to access disk resources using this account. The only workaround is to go to the agent jobs, change the login under which they work from the proxy account to an actual windows account.
Has anyone come across this issue? I am forced to use the sql agent account and running the replication agents under way more privilages than I would like to.
TIA

In our lab we have 2 clustered instance of Sql server 2018R2 as follows
Virtual Server Name
IP SqlVir 10.1.1.6
SqlVirDr 10.1.1.12
The Data is SqlVir is replicated manually every day to SqlVirDr.
We had to change the Virtual Server name of SqlVirDr to SqlVir so that all dot net applications accessing SqlVir could continue to access the database without changing the application string.
For that purpose I deleted the computer name SqlVir from the domain and its IP 10.1.1.6 from DNS. Then I went to the failover cluster manager of SqlVIrDr right clicked the Sql services selected the properties and changed the DNS name from SqlVirDr to SqlVir.The applications then could access the data.However when I changed the network IP address from 10.1.1.12 to 10.1.1.6 the Sql services was found to be down.
Perhaps the procedure I followed in deleting the computer name from domain and the IP from DNS was wrong.What exactly is the steps that I should follow to achieve the above objective.

We have an Sql Server 2008R2 Clustered production instance by name 'ProdVir' configured in 2 nodes(Active-passive) withWIndows Server 2008 R2. We also have another clustered instance as disaster recovery by name 'VirDr' configured again in another 2 nodes of Windows Server 2008 R2. Every day morning there is mainatenace plan which backups all the database in production and another maintenace plan in the disaster recovery server 'VirDr' which restores the backups into the VirDr instance.
I would like to know that in an eventuality of a disaster in the clustered production instance of 'ProdVir'. could we rename the the instance VirDr(meant for disaster recovery) to ProdVir and also change the Ip addresses accordingly so that the application programs do not have to change the details for the datasource in the connection strings.

My issue is that: here have two datamirror servers, and when the first fail, mirror needs to assume with the same name.
I'll try explain: SD01 - Primary, SD02 - mirror. If SD01 fails, SD02 assumes called SD01. By the way, the instances are in same domain, but not in same computer.

I am using sql2012 with partitiondb custom installation over 6 dbs on 4 servers, ~200GB per db. I am looking for the perfect graphic tool (similar to Perfmon+Activity Monitor) where I can monitor a wide-scope SQL environment. I am interested in data / log / table / index growth, buffer cache hit ratio, average wait time, physical/logical reads/writes and such. I am interested in real-time / time-range metrics. I know I can issue immediate queries against dm_os_performance_counters / dm_os_buffer_descriptors / dm_exec_query_stats and get some of the relevant data, but is this the only way?Also, for your opinnion, what are the most crucial metrics to monitor when dealing with multiple dbs?

I 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?

I want to know more details about the Clustered Index Delete. Is that Clustered Index Delete in the execution plan is good or bad or we can neglect that cost. Is there any way to avoid that clustered Index delete operator from the execution plan.

- What are your thoughts on adding clustered index on datetime (createdDate , native GUID) column. The data will be be physically organized in the clustered index allowing range operations to perform its duties. But will the GUID column make any impact ( drawbacks) should it be made part of the clustered key ?
The GUID column will provide the lookup with the required indexes to support.

I created a NC index as suggested by missing index DMV(of course I don't create them blindly). This one seemed to be a useful index but I now see from index usage stats that it only got scanned 50 times in 4 days.No seeks, no lookups. So is it a good idea keeping such index.The table on which this index is created is used more for reads and less for writes.

I've created a table which will hold staffing data (name, grade, etc.) and any shifts that are going to be entered. I've got some test data in the table.
The base table looks like this:-
CREATE TABLE [dbo].[tbl_ForecastShifts_New](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Ward] [nvarchar](255) NULL,
[StaffBand] [real] NULL,
[StaffMemberName] [nvarchar](255) NULL,
[Code] ....
I've attached a spreadsheet with the test data from the table and the required layout on the second tab.
I've created a view which displays the data as I want it and I need to attach this to an MS Access front-end for the users to input/edit the data in the table with the use of a Access form.
The view I've created looks like this:-
CREATE view [dbo].[vw_Forecast_Staffing] with schemabinding
as
select
s.Ward
,s.StaffBand
,s.StaffName
,d1.Date1
[Code] ....
It displays all the staff members and any shifts they've been given for a 7-day period with day 1 begin supplied by the user.
The user will also supply the ward they are interested in viewing.
When I attached the view to Access it becomes read-only as it doesn't have any indexes on it.
I can't create a clustered index on the view as there are derived tables.

Native backups to NAS do not complete.We have been experiencing an issue whereby our native backups are hanging with status': SUSPENDED/ RUNNABLE...I ran select * from sys.sysprocesses. All of the backup SPIDs processes show BACKUPTHREAD/PREEMPTIVE_OS_FILEOPS
This first occurred last Wednesday evening. When I discovered this on Thursday, I attempted to kill the backup jobs. This also hung with 0% completed/0% time remaining. Backups hung on more than one instance.That evening, I attempted to restart the instance which also failed with something along the lines of: could not start MASTER file in use.
I then restarted the server--which I really did not want to do--and this cleared it. I was also able to manually kick off maintenance plans (DBCC CHECKDB and full backup) without issue.I was off Friday and the weekend. I came in this morning and found the maintenance plans (diff/tlog backups) did not complete in some of the instances--in one case, the instance affected now was not affected before. They appeared to have hung on their next scheduled kickoff which was later that night after I went home
Remembering the "file in use" error, I have run process monitor to see if anything unusual had a lock on any files. I saw only SQL Server and Double-Take processes accessing log files.Being a relatively new DBA, I am user where to go next in trying to track down the cause of this issue. This is fairly urgent as one of the instances that has had this problem both times is our production SharePoint environment.

We have 5 instances on our clients old machine with SQL 2005, now they want us to move on cluster environment with SQL 2012.
Once I have installed and configured SQL cluster with single instance, but how to install SQL Cluster environment for Multiple instances.
Should I install all the instances first and than have to configure cluster ?
OR
Is there any way that first I will install cluster and than we can add the instances ?

What I have- Sql server 2012 (Standard Ed) Cluster on Windows 2012 R2 with both instances running on the same node- just to save on License, i.e. technically it’s Act/Pas cluster.
What I am looking for- how to configure cluster (e.g. via quorum, etc) to force both instances failed together? Means if for some reason 1-st instance will fail to node 2 another instance should follow (otherwise it will be Act/Act cluster and 2-nd license is required).
If there is no standard way (cluster configuration I mean) to do it I should create some custom process to monitor where each instance is running.

Curious what the industry standard is combining multiple instances on single server ?
Right now i have separate servers for OLTP, SSAS, and SSIS, and for OTP have Development, Test, and production environments. Im considering combining the SSIS and SSAS services into additional instances on each environment servers.
Now (Production)
OLTP
SSAS
SSIS
After
1 Server with 3 separate instances for SSAS, SSIS, OLTP. Then replicate this model through the environments to utilize development and testing.

I am in the process of writing a generic PowerShell script (that executes T-SQL statements) to copy all or some databases from one SQL Server 2012 SP2 instance to a second instance that runs SQL Server 2012 SP2 or higher. The script is designed to be used on demand, and part of its execution will involve reconciling the logins between the source and destination instances.
I am looking for a reliable way to reconcile the logins between the instances in a somewhat repetitive (i.e., "on demand") fashion. There is no SSIS in the environment; so the SSIS transfer logins task to not available to me.

I have clustered SQL server machines(SSserver1 and SSserver2). I need to restore a database from another standalone server to this clustered environment. In this case do I need to restore the DB on both the nodes that are part of the clustering(SSserver1 and SSserver2) or Just can I do it on one of them?

I am trying to tune a process that is running slowly. I analyzed the process using the Database Engine Tuning Advisor, and it recommended the creation of 3 indexes, all non-clustered:
1) ColA, include ColB
2) ColA, include ColC
3) ColA, include ColD
So... I created a single non-clustered index on:
4) ColA, include ColB, ColC, ColD
That should do the same thing, right? A look at my execution plan shows that the index I created is being scanned -- 3 times. What is puzzling me, though, is that the Database Engine Tuning Advisor is still recommending I create these 3 separate indexes, even with the index (4) that I created in existence.
If it matters, ColA, ColB, ColC and ColD are all int FKs.

I have 2, 2 node clusters
PROD1(cluster 1) Clustered SQL instance1
PROD2(cluster 1)
DR 1 (cluster 2) Clustered SQL insatace 2
DR 2 (cluster 2)
I have set an availability group up from the PROD instance to the DR instance.How does the AG behave if a SQL instance fails at PROD? Does it try to fail over to Node 2 on Prod before going over to DR? or bring the Replica at DR online straight away? Can we only use Manual Failover of the AG in this scenario to make use of the High Availability of the Windows cluster?
