Replication :: Multiple Instances On Same Instance Of Server 2012 SE

Jul 13, 2015

I am currently having publisher(database A), subscriber (database B) and distributor on the same instance for a test environment that is using a uni directional transactional replication. Now I need to setup another unidirectional transactional replication in the same test instance but for a different database. Publisher database is D and subcsirber database is E.

SQL 2012 :: Mirroring Endpoint Multiple Instances On Same Server

Jun 18, 2014

I was told that if I wanted to setup mirroring between multiple instance on the same server that each endpoint had to be different number. Is that true? Or can I use the default 5022 for each instance?


Use endpoint 5022

Use endpoint 5022


Use endpoint 5022

Use endpoint 5023

DB Engine :: Multiple Instances With Processor Affinity Or One Instance

Oct 22, 2015

We are currently looking at consolidating 10 servers into one cluster server.

Some servers may be busier than others. Is there any reason to split them up and give the busy databases specific CPUs or is it always better to have them on one instance?

SQL Server 2012 :: Query To Find Distinct Multiple Instances Of A Pattern In A String?

Apr 30, 2015

One of my varchar columns in a table has multiple key words enclosed in a pattern of special characters.

Eg: William Shakespeare was an English [##poet##], [##playwright##], and [##actor##], widely regarded as the greatest [##writer##] in the English language and the world's pre-eminent [##dramatist##]. He is often called England's national [##poet##] and the "Bard of Avon". His extant works, including some collaborations, consist of about 38 plays, 154 [##sonnets##], two long narrative [##poems##], and a few other [##verses##], of which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other [##playwright##].

I need to write to query to find all distinct key words that are enclosed within [## and ##]. My query should yield the following results from the string in the example above

[##playwright##] -- 2 occurrances, but I need it only once in my result set
[##poet##] -- 2 occurrances, but I need it only once in my result set

I need to run this on a large table, so I am looking for the best possible way to minimize any performance issues.

Just give you sample code, I have provided below 2 separate snippets, one with table variable and another with temp table.

DECLARE @MyTable TABLE (MyString VARCHAR (8000))
INSERT @MyTable VALUES ('William Shakespeare was an English [##poet##], [##playwright##], and [##actor##], widely regarded as the greatest [##writer##] in the English language and the world''s pre-eminent [##dramatist##]. He is often called England''s national [##poet##] and the "Bard of Avon". His extant works, including some collaborations, consist of about 38 plays, 154 [##sonnets##], two long narrative [##poems##], and a few other [##verses##], of which the authorship of some is uncertain.

SQL 2012 :: Monitoring Multiple Instances

Oct 22, 2015

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?

SQL 2012 :: Cluster With Multiple Instances On The Same Node?

Jul 14, 2015

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.

SQL 2012 :: Combining Multiple Servers Into Instances

Oct 14, 2015

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)


1 Server with 3 separate instances for SSAS, SSIS, OLTP. Then replicate this model through the environments to utilize development and testing.

SQL 2012 :: Determining MAXDOP And Memory Configuration For Multiple Instances?

Sep 18, 2014

We are just finishing our migration to SQL 2012. In our old environment, the instance which held our SharePoint databases also served other applications. We did not experience any performance related issues in the past due to this.

SharePoint basically requires MAXDOP to be 1, which is correct on the old server. Since this configuration may not be ideal for other applications that may be put within our environment, we our entertaining the idea of isolating SharePoint into its own instance, probably on the same box.

My manager wants me to come up with performance trace data to better prove that we need to go this route since we apparently have had issues in the past by blindly following Microsoft's best practices.

1.MAXDOP configuration - I understand this may be a 2 pronged approach that would require looking at various execution plans and CPU related counters in Perfmon. SharePoint likely requires a maxdop of 1 due to the nature of the application (lots of concurrent processes). What is the best way to show this need graphically?

2. Memory configuration for multiple instances - Does the Total Server Memory reveal all the memory that a given SQL instance is utilizing? Should I use this counter to identify appropriate min/max memory configurations for multiple instances on a single cluster?

The problem with the perfmon approach is that it's scope is limited to just the server. Since our SharePoint environment is currently being shared with other applications, I understand that I may have to utilize DMV statistics to narrow down my analysis.

SQL 2012 :: Select Statements And Ended Up Seeing Multiple Cached Instances Of Same Stored Procedure

Nov 24, 2014

I ran the below 2 select statements and ended up seeing multiple cached instances of the same stored procedure. The majority have only one cached instance but more than a handful have multiple cached instances. When there are multiple cached instances of the same sproc, which one will sql server reuse when the sproc is called?

SELECT, o.object_id,
ps.last_execution_time ,
ps.last_elapsed_time * 0.000001 as last_elapsed_timeINSeconds,
ps.min_elapsed_time * 0.000001 as min_elapsed_timeINSeconds,
ps.max_elapsed_time * 0.000001 as max_elapsed_timeINSeconds

SQL 2012 :: Multiple Availability Groups On One Instance

Aug 12, 2013

From what I understand, one SQL Server 2012 instance can host multiple availability groups. That should allow, for example, the following situation - one SQL Server 2012 instance containing three primary replica databases - each one part of a different availability group - and each availability group's secondary replica located on a separate SQL Server 2012 instance.

Can you have three SQL Server 2012 instances, each with one primary replica database and have all three secondary replica databases on one SQL Server 2012 instance? So instead of, as above, going from 1 primary server to 3 secondary servers, this time we're going from 3 primary servers to 1 secondary server? The one secondary server would then contain all three secondary replicas for each of the 3 separate primary replicas.

This would mean that the single server (where all three secondary replicas reside) was part of three separate Windows Server Failover Clustering clusters.

Is this scenario possible?

SQL 2012 :: Multiple Database Servers - One Instance Name

Apr 24, 2014

Scenerio : To keep a very large system running optimally in a VM cluster, Take PR01 and make PR02, PR03, PR04. Distribute the 45 databases and 9T+ of disk across multiple VM guest.

Each PR## is a SQL Server 2012 Enterprise guest on a VM 5.1 cluster.

So instead of PR01 needed 16 core and 128g of memory, each one will have 4 core and 32g of memory. Making VM HA more manageable. (yes, DRS rules will apply). Also provides more HBA paths and distributes i/o over more physical disk on the SAN.

Instead of a connection string having to know PR01.dbo.UserDB01, PR02.dbo.UserDB03, ect the connection would be PRDB.dbo.UserDB01. That way if needed 1) UserDB can be moved to any of the PR## 2) new PR05, PR06 can be added as needed. The end user and processes are not allowed to touch system databases, no PR## will have a user DB called the same name.

There are seperate VM guests on other VM clusters and Citrix servers that need access to PRDB. As things expand and move around, none of the connection strings need to be changed.

I am looking into RadWare and modifing level 7 information, but that is iffy and $$$$$$.

How To Uninstall Server 2008 Express Instance With Other Instances Present

May 15, 2015

This is probably easy for some who have done it, but I have an installed Instance of SQL Server 2008 Express or SQL Server 2008 R2 Express I'll call Instance CCC and need to remove it.  I have two other Express instances I'll call Instance AAA and Instance BBB.  I want to uninstall Instance CCC without affecting the other two instances or the software that uses them.  Instance CCC should have been installed as a SQL Server 2012 Express instance, so I need to remove the 2008 Instance of CCC and reinstall it as 2012.  In all cases, I'm talking about SQL Server Express.  Full SQL Server is not installed.  

The Instances are all installed on a Windows Server 2008 R2 Standard server.   

I have read that I can do this through Control Panel  >  Programs and Features, but that I can corrupt or mess up the other instances (AAA and BBB) if I don't do it right.  I'm uneasy about this, not having done it before, and do not want to affect the users of the AAA and BBB instances!

SQL 2012 :: Clustered SSAS Unable To Connect To Named Instance (instance Not Found On Server)

Mar 20, 2014

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.

I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.

I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.

Should I be able to connect as serverinstances for a named clustered instance in 2012 ?

Multiple Instances Of SQL Server 7 & 2K

May 22, 2001

I am running SQL 7.0 as the default instance and SQL 2K as a named instance. Each is using a different port....7.0 is using port 1433 and 2K is using 1024. Everything appears to be up and running fine on the server. However, I am not able to access the 2K instance from a client. I have tried to use both TCP IP and named pipes setting them up using the server network utility and the client network utility. No luck anywhere. I continue to get connection errors...check network documentation...

Install AS On Multiple SQL Server Instances?

May 12, 2002

Dear Listers,

1.) Is it possible to install Analysis Services on multiple SQL Server 2000 instances? If it is, then can you instruct me as to how to perform the install. If it is not possible, then does one restrict access to cube data via the Database Role Manager?

ie. The host box is - DOILAB30 with Analysis Services & SP2
Instance - DOILAB30/DOILAB30_FIN (Can AS be installed here?)

Do I severely restrict the membership of OLAP Admins?

2). Re. AS maintenance. - How do I backup and restore OLAP dbs/cubes etc. Following a restore, what issues, such as cube users/permissions should I be aware of? (if any).

Multiple Reporting Instances On One Server

Dec 17, 2007

Hello all,

I am trying to built a general demo machine for our multiple resellers.

Is it possible to have multiple database instances (one per reseller) with each of them their own reporting instance, running on the same server (also same IIS). In our DNS and in the IIS settings i will reroute the specific reseller to his specific reporting url (eg: (this is not a real url), will be rerouted via dns to the
specific reporting url for reseller one ... and so on.)

Each reseller must be able to has it own reports, subscriptions, models and access to reportbuilder.

Can this be accomplished ?

I have tried already a few times but get stuck when i want to upload reports/datasources to the specific websites. Also i have encountered the fact that if i succeed in uploading data to one reporting site and i want to upload different data to
another site, the initial site is also changed with the data of the second upload.

Can anyone point me into the right direction how to solve this problem .

Can You Mirror To Multiple Instances On Same Server Via One Endpoint?

Oct 29, 2007

Hi all,

Can a MIRROR server have mirrored databases on many instances or must all of the mirrored databases on a server reside on one instance?

This initial implementation worked fine:

PRINCIPAL ServerPROD1instance01 endpoint1430
MIRROR ServerDRinstance01 endpoint1440
WITNESS ServerZ endpoint1450

This second implementation (different PRINCIPAL server to same MIRROR but to a different instance)

PRINCIPAL ServerPROD2instance5 endpoint1430
MIRROR ServerDRinstance02 endpoint1440 <<same mirror server but different instance
WITNESS ServerZ endpoint1450

I know that you can only install one endpoint on each server. Does that mean that the endpoint can only resolve to one instance though?

The second implementation looks fine until the final step (start mirroring). I get the following error:

An error occured while starting mirroring
Alter failed for database 'test'
An exception occurred while executing transaction-sql statement or batch
The remote copy of database 'test' does not exist. Check the database name and resissue the command

I have created the test database in instance02 and rolled a log onto it. It is currently in recovery mode - waiting patiently for another log.....

I have read books online and 2k5 unleashed but can't see anything that relates to an implementation across mutliple instances on the DRmirrored servers.

Has anyone tried to do this? Can you confirm its possible?

Many thanks in advance...

Merging Multiple Report Server Instances Into One

Sep 18, 2007

Greetings... I'm working at consolidating several Reporting Services installations into one so we can decommission some old servers. We have two Report Servers that are in SQL Server 2000 and three that are in SQL Server 2005 (none are in a web farm configuration). I can upgrade the 2000 databases to 2005 format just fine, but now how do I merge these five ReportServer/ReportServerTempDB databases into one? I'm reluctant to redeploy reports to the "official" Report Server because we lose security, subscription, and scheduling information by doing that. So redeploy would cost us time and data loss over hundreds of reports, thus my hope to merge the databases at a data level. Is there a tool to automate this process, or has anyone tried this before? Thanks in advance.

Can You Have Multiple RS2005 Instances Running On Server 2003?

Is there some trickery or details involved with running two instances of Reporting Services?

SQL Server Configuration Manager: SSL And Multiple Instances Problem

Mar 31, 2008


We are trying to setup a number of SQL Server 2005 database instances on a single server. The server has multiple IP addresses bound to its network interface (card). Each instance is configured to listen on a specific (unique) port on and port 1433 on a specific (unique) IP address configured on the network interface. Finally, there is another instance of SQL Server (which also has the Reporting Services, Analysis Services and Integration Services installed) that does not allow remote connections and has TCP/IP disabled.

SSL is configured for all instances, apart from the non-remote connections instance, as follows: The same self-signed certificate is specified for every instance. This certificate has been configured for all ports and port 1433 on all IPs in use for any of the instances using httpcfg as documented. The Force Encryption option is enabled and the Hide Instance option is disabled.

All appears to work correctly, and the "The certificate was successfully loaded for encryption" message appears when sp_readerrorlog is run, for the instances it is supposed to. However, at some point a problem occurs. The Force Encryption and Hide Instance labels _disappear_ (leaving blank spaces in the grid) from the interface, with the drop-down settings still visible. This seems to happen after installing an additional instance, although on one occasion it was after the 3rd was installed and on another occasion the 4th. Uninstalling the instances (even all of them) does not seem to help - only removing SQL Server 2005 completely and re-installing allowed the labels to re-appear.

Another concern is that after problem occurs, it appears that the settings are not being interpreted correctly. Even if the certificate is disabled for an instance, the message "The certificate was successfully loaded for encryption" appears, instead of the instance using a self-signed certificate. Additionally, on some occasions, the values for the Force Encryption and Hide Instance are swapped (or at least the values in the positions that used to be inline with the labels for these options).

As an additional note, various IIS Web Sites are configured on each of the IPs on the network interface. These are also using the same self-signed certification for SSL and are all using port 443, which none of the SQL server instances are configured to use.

Any feedback or suggestions on this would be appreciated. Thanks.
