ActivePassive Cluster
Sep 16, 2002
I have been tasked with managing a SQL Cluster. I have no experience with this but have managed to get it up and running and can move it from one node to another and everything appears to be running. I just have one item I need confirmed. In this type of configuration is it correct that the SQL services can only run on one node at a time? If node 1 goes down then the sql services on node 2 will be started? I wasn't sure as I tried to start the services on node 2 and received a non-specific error.
Any help would be terrific. Thanks.

yesterday i installed sql2k5 on a activepassive cluster and for some strange reason the mssqlserver service does not want to start up on the node that i installed it on but if i fail it over to the passive node it will start fine. system info below:
system info:
* win2k3 enterprise r2 (x64) cluster activepassive*
* sql2k5 enterprise (x64) clustered*
the win2k3 cluster works fine. i installed the msdtc service running as a cluster as well and that works fine.
both servers are identical to each other. sql virtual server is running on the passive node which is now the active node. any ideas?

Do I have install sp2 on each node in the cluster or do I just need to install it on the active node and reboot? Do I need to pause the active node? I was looking for some documentation for this and didn't mention anything regarding pausing the active node in the cluster in order to apply the sp2 for sql 2005.

I am in the process of moving databases from a SQL 2005 Standard version to a 2-node 2014 cluster.All of my 2005 databases back up successfully.They all restore without issue except for one database that has a full text catalog. I get this message
Msg 7610, Level 16, State 1, Line 2
Access is denied to "fileStoragedataMSSQLSERVERFullTextCatalog", or the path is invalid.
Msg 3156, Level 16, State 50, Line 2
File 'sysft_FTCatalog' cannot be restored to 'fileStoragedataMSSQLSERVERFullTextCatalog'. Use WITH MOVE to identify a valid location for the file.
Msg 3119, Level 16, State 1, Line 2
Problems were identified while planning for the RESTORE statement. Previous messages provide details.
Msg 3013, Level 16, State 1, Line 2

I went as far as giving the folder full access to everyone temporarily and received the same error.

Slq Server 2012.
After is completed, it was successful, I realized I specified the wrong Instance Root directory.

Can I build a cluster by adding the cluster service, then the SQL instances, then add the other nodes and their passive SQL instances?I would lean to building the cluster first, the add the SQL instances.

I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?

I have following script which i am planning to run to drop all non-clustered primary keys on a database and then created as clustered. I am using someone else's script so don't know how to modify this. Some of primary key columns are used in references in other tables.
is there anyway i can drop the existing primary keys and using their original script then create again as clustered including restoring all foreign and reference keys and unique or no unique.
DECLARE @table NVARCHAR(512), @tablename NVARCHAR(512),
@sql NVARCHAR(MAX), @sql2 NVARCHAR(MAX), @sql3 NVARCHAR(MAX),
@column NVARCHAR(MAX);
DECLARE @indexname NVARCHAR(512);
SELECT name As 'Table'

Hi
We are planning to upgrade the SQL Server in our production environment from SQL Server 2000 to SQL Server 2005. This is a 4 Node cluster environment with 3 Databases on 3 Virtual instances. The main requirement is to achieve this with no/minimal downtime.
Could you please suggest or direct me to any documentation for the best practices used to upgrade such an environment?
Thanks

We have (had) an active/active cluster. 2 physical machines,
each running their own instance, clustered together. Node1/Ins1 and Node2/Ins2.
Node2 failed and Ins2 failed over to Node1 as it should. Node2 required that we
rebuild the server (rebuild = reinstall O/S). Now we need to get Node2 back
into the cluster and get Ins2 failed back over to Node2.
Does anyone know, for certain, the correct steps to accomplish this? Obviously,
we could backup everything and completely destroy Ins2 and recreate it on Node2
then rejoin the cluster. But I'm looking for something less destructive.
Is it possible to reinstall SQL, then rejoin the cluster, and then fail Node2
over? Or will there be registry conflictions?
Any help would be appreciated. Also, if you have any links to some official
documentation, that would be great too.
Thanks

We're upgrading a SQL Server 2000 cluster (Active/Passive) running on Windows 2000 Server to a SQL Server 2005 Cluster running on Windows Server 2003. We can't purchase new hardware and we have no spare hardware. We also need to move from Windows 2000 Server to Windows 2003 Server at the same time. We want to keep downtime to a bare minimum.
What we were thinking was the following steps... Anyone try this?
1. Break the link between the servers.
2. Install a fresh copy of windows 2003 server on one side along with SQL Server 2005. While this step is running, the active node would still be live on Windows 2000 Server and SQL Server 2000 serving our customers.
3. Restore a copy of a backup from the active production side to the node we're upgrading and at that point we would bring the active node down, switching the active node to be the newly upgraded server.
4. As a final step, the old active node would now have the link to it broken, we would install a fresh copy of windows 2003 server on it and sql server 2005. At this point we would bring it back into the cluster and the cluster would be complete again.
Thoughts?

Can the SQL Cluster Virtual IP be the same as the cluster IP?
Can I set up the cluster like:
Node 1:10.0.0.1
Node 2:10.0.0.2
MSCS Shared:10.0.0.3
SQL Virtual:10.0.0.3
or do they need to be unique?

I have two Windows 2000 servers (Advance Edition) to form a Windows Cluster. I also install MS SQL 2000 Enterprise Edition on the cluster to form a MS SQL cluster. Now, I want to upgrade the hardware and OS (but keep on using SQL 2000), so I install Windows 2003 server Enterprise Edition on two new servers to form a new Windows Cluster. I am planing to install MS SQL 2000 Enterprise Edition on the new cluster, so the old SQL cluster and new SQL cluster are side by side. I would like to know how to setup a new SQL cluster (I know it has problem to rename SQL Cluster name, so how to fix this problem)? And how to transfer everything (such as system databases, users database, sql user account, password and maintenance plan jobs etc) from old SQL cluster to new SQL cluster? And how to switch over from old SQL cluster to new SQL cluster?
Thanks a lot !

According to microsoft, we can cluster SSIS service but it is NOT RECOMMENDED.
http://msdn2.microsoft.com/en-us/library/ms345193.aspx
Now this is the situation that I have where I need to understand how SSIS works?
Enviornment: Active Active cluster enviornment for SQL server with SSIS server installed as stand alone as default on both node.
Name: Node 1 Node 2
--------- -------------- ---------------------
Server name: Nd1 Nd2
SQL server name: cs-nd1in01 cs-nd2in02
SSIS server name: Nd1 Nd2
BTW, this is cosolidated enviornment so there are more than one application expected and resides on each instance of SQL server.
The question is around SSIS, what would be the best practice to develop SSIS package that can work with above envoinrment.
Secnario: What if my Nd1 fails. SQL server cs-nd1IN01 will be failover to Nd2 and it will be available. But How about SSIS packages? How that understands
to use Nd2 SSIS as Nd1 SSIS is not available. Is anyone has similar experience to setup SSIS in cluster envionrment but as non-cluster service?
Please help. Thanks in adavance.

I am trying to configure a 2 node SQL cluster. MSCS is configured and is failing over correctly, however when I start the installation of SQL Server, and specify the IP address of the virtual server and hit next, the installation hangs, and stops responding. I have ran comclust.exe on both nodes and verified that MSDTC shows up in the cluster administrator. I have searched high and low to no avail---

I realize this is like arguing politics or religion, but I have some wide tables that have frequent inserts on. SOme of these tables have millions of rows. I have seen pros and cons of having clustered indexes on tables like these. The one curve ball is that this is a vendor supplied app that I have little control over (ie how they call data is all dynamic sql). I thought the rule was not to cluster index on large tables with frequent indexes, but happy to hear other opinions

Hello everyone -
I need to install SSL on a SQL 2000 cluster system.
I have secured a certificate for the cluster name of the system with a fully qualified domain name.
I have placed the certificate on both nodes of the cluster in a location that both nodes has in common, but not in the cluster scheme.
I do not want the certificate to be applied to the whole server, just on a client by client basis.
thanks for the help!!

Hi All,

3) Lets say SQL server fails on Server A but Oracle is still working fine on Server A, Will there be a Failover?
Thanks in Advance

Hi there
We have a new SQL cluster 2005 and we've done the testing for fail over with couple schenario based on Ms Documentation (prior installing SQL as well as after installing). We also did the benchmarking by running Perfmon as well.
In term of house keeping, is there any things that you guys do apart of configuring the SQL itself. Perhaps stress test (for SQL) etc etc.
Regarding stress test, do you any software that can do this?
Thanks
