If the primary master server become permanently unavailable, following a hardware failure for example, what could steps to promote the secondary master to the role of primary master.
The Secondary server is a updateable subscriber and there are other servers also in the cluster with read-only subscription.
As per my tests if primary goes down, we can create new publication on secondary and create its subscriptions.everything should work fine after that.
if primary comes up in any case that can create problem in new cluster so we should take care in this regard
During the installation of Adding node to a SQL Server failover cluster(On passive node) getting error like.. The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.We run the below commands but didn’t get any resolution & got the same above error .
1<sup>st</sup> Method…
1. Open console command (Run->CMD with administrator privileges).
2. net stop winmgmt
3. Rename folder %windir%System32WbemRepository to other one, for backup purposes (for example _Repository).
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.
Does anyone here know how to properly add a secondary IP address (VIP) to a SQL 2005 failover cluster? I have looked for articles, but so far I can only find references to how to change the VIP on a cluster, not how to add additional VIPs.
I have added the VIP as a resource in the proper resource group, and added it as a dependency to the SQL Server resource, and although the active server properly registers the secondary VIP, the SQL Server process does not listen on that IP. Vexing.
We had a big issue today during maintenance work in our SQL environment.
So our environment: - 2x SQL Server 2014 Enterprise on Windows Server 2012 R2 (SRV1 and SRV2) -- Both Hyper-V VMs on different Hosts -- Both configured to an Windows Failover Cluster and AlwaysOn Availability Group (AG1) -- AG Listener: AG1_lis -- No shared storage (each Hyper-V Host has its own local storage) -- Asynchronous Mode -- SRV1 is primary, SRV2 is secondary SQL node
What happened? - Shutting down Windows on SRV2 due hardware maintenance - Cluster goes offline, AG1 goes offline -- Error message: "Stopped listening on virtual network name 'AG1_lis'." -- Error message: "The availability group database "DatabaseXY" is changing roles from "PRIMARY" to "RESOLVING" because the mirroring session or availability group failed over due to role synchronization."
Results? - AG1_lis wasn't available for our applications and they stopped working properly because database connection was lost!
I think, I HOPE, this is not the normale behaviour when one node is shutting down (especially the secondary node!)
I know now that AlwaysOn feature HAS to be installed/configured on a Windows Clustering environment, BUT the secondary replicas, like the Disaster recovery replica residing in a different Data Center HAS to be also in a Windows Clustering environment or can it reside on a SINGLE SQL Server INSTANCE?.
Server : Windows server 2008 DB Server : SQL Server 2008 (SP1)
Here are the series of events which happened.
1.) Event ID: 1135 Cluster node 'XYZ' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
2.) Event ID: 1049 Cluster IP address resource 'SQL IP Address 1 (XYZ)' cannot be brought online because a duplicate IP address '10.9.8.113' was detected on the network. Please ensure all IP addresses are unique.
3.) Event ID: 1069 Cluster resource 'SQL IP Address 1 (XYZ)' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
4.) Event ID: 1049 Cluster IP address resource 'Cluster IP Address' cannot be brought online because a duplicate IP address '10.9.8.112' was detected on the network. Please ensure all IP addresses are unique.
5.) Event ID: 1069 Cluster resource 'Cluster IP Address' in clustered service or application 'Cluster Group' failed.
6.) Event ID: 1066 Cluster disk resource 'Cluster Disk 25' indicates corruption for volume '?Volume{88552e6f-aea2-11df-9790-0026b92fffa7}'. Chkdsk is being run to repair problems. The disk will be unavailable until Chkdsk completes. Chkdsk output will be logged to file 'C:WindowsClusterReportsChkDsk_ResCluster Disk 25_Disk16Part1.log'. Chkdsk may also write information to the Application Event Log.
7.) Event ID : 1066 Cluster disk resource 'Cluster Disk 26' indicates corruption for volume '?Volume{88552e05-aea2-11df-9790-0026b92fffa7}'. Chkdsk is being run to repair problems. The disk will be unavailable until Chkdsk completes. Chkdsk output will be logged to file 'C:WindowsClusterReportsChkDsk_ResCluster Disk 26_Disk4Part1.log'. Chkdsk may also write information to the Application Event Log.
8.) Event ID: 1049 (Same message as point 2)
9.) Event ID: 1069 (Same message as point 3)
10.) Event ID : 1049 (same message as point 4)
11.) Event ID :1069 (same message as point 5)
12.) Event ID :1205 The Cluster service failed to bring clustered service or application 'Cluster Group' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
13.) Event ID: 1069 Cluster resource 'Cluster Disk 17' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
14.) Event D : 1049 (same message as point 2)
15.) Event ID: 1069 Cluster resource 'SQL IP Address 1 (XYZ)' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
16.) Event ID : 1205 The Cluster service failed to bring clustered service or application 'SQL Server (MSSQLSERVER)' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
first of all,I went through all the logs, and could not find the reason for fail-over initialization. There should be some thing logged why the failover happened? secondly after failover the service was not coming online due to duplicate IP address detection.
Later when we try to manually bring the service online from cluster management it comes online successfully. I don't understand how would duplicate IP address get resolved when we start manually.
Lastly we see few errors related to physical disk resource between failover retries, is this could be the correlated to failover error ?
I am trying to upgrade a SQL Server 6.5(Cluster) to SQL Serevr 7.0 (Cluster)..I already have an intsllation of 7.0(On a Cluster),so this means that 6.5 and sql 7 are on seperate cluster's ,if i try to upgrade from 6.5 Cluster to 7.0 Cluster is asks me to uncluster 6.5 and 7.0 is this correct ,assume i cannot break the cluster then what???.. what is the best way i can achieve this functinality.....
I am writing a little systems monitoring application to send SMS messages to my mobile phone. For example when disk space reaches a certain maount my program will raise an alert that fires a VB app, that sends a SMS message directly to my mobile. We operate an active/active cluster (SQL7 NT4) and I want to be informed when one of the clusters fails over. I have managed to find out when the clusters are 'off-line' by reading the 'PersistentState' variable from the registry as follows:
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?
I have some doubt about the IP Required for configuring cluster(both Window and SQL server)
Details : ---------- How Many IP(Public & Private) Required for 2 Node Active/Passive both window and SQL server Cluster ?
IP(Public & Private) Required : --------------------------------------- 1 : For Window Clustering : 2 node Active/Passive Cluster ? How many ip ? 2 : For Sql Server Clustering : 2 node Active/Passive Cluster ?how many ip ? 3 : Is there any mathematics for that ? How to analyse the IP requirement ?
What are the minimum permissions required by the SQL Server 2005 Upgrade Advisor (UA)? I could not find it in the documentation.
Obviously being a local Administrators Windows group and a member of sysadmin SQL Server role will do the trick.
But will being a member of only the sysadmin SQL Server role be enough? I know that the UA does want to read the registry.
Running it under just sysadmin generates the following type of errors:
Database Server PreUpgrade Requested registry access is not allowed. WINSOCKPROXY
Database Server PreUpgrade Requested registry access is not allowed. FTUNSIGNEDCOMPONENTS
Database Server PreUpgrade Requested registry access is not allowed. NETPROTOCOL
Database Server PreUpgrade Requested registry access is not allowed. FTMULTIPLEINSTANCES
Database Server PreUpgrade Requested registry access is not allowed. INVALIDNAMEDPIPE
Database Server PreUpgrade Requested registry access is not allowed. FTCOMPONENTREG
Database Server PreUpgrade Requested registry access is not allowed. FTACCTPASS
The issue then is whether these are significant or not. If the UA is only reading the registry to determine if SSAS, DTS, etc is installed then that is not important. But if it is affecting the end result because it cannot read critical information from the registry that is another matter.
I have DBA that is convinced that they need domain admin rights to install SQL 2005 into an existing cluster. The domain groups and service accounts for SQL have been created already. Is having domain admin rights required during the install of SQL 2005 in a cluster?
Have a production server, 12 Enterprise, and we are adding a new app to an existing instance. Next app needs SSRS and that was not put in the install request a year ago for the instance.
I do not think a reboot is required but have been wrong before. There are no SPs applied to this server and only last week we were given go ahead from one app vendor to apply SPs. That would have been done in monthly maintenance cycle next weekend. Our test server is doing just fine with all apps on SP1.
Have recently performed an in-place upgrade of a 2 instance sql cluster from 2000 to 2005. The upgrade process went relatively smoothly. However, I am running into problems installed sp2. The first problem that I run into is that I have resrcmon.exe locked. I can click next, which is fine, but once I get past that point I get stuck during the installation process. I am updating DatabaseServices and Integration Services. It gets stuck on 'Awaiting first complete passive cluster node SQL-Test'. Does anyone have any ideas? Thanks, Tim
I have upgraded many standalone sql server instances however never a cluster.
I have an active active 2 node cluster. Each running an instance of Sql Serevr , 1 default and the other a named instance.
All i can find in BOL is "How to: Upgrade to a SQL Server 2005 Failover Cluster (Setup) ", however this does not tell you how to upgrade and existing cluster.
Is there anything different ?
Will the upgrade detect the cluster and upgrade binary files on both nodes automatically etc? In other words is there anything different i have to be aware of when upgrading sql server instances cluster?
Good Morning! I am beginning the process of moving SQL 2000 databases to SQL 2005 cluster. Has anyone already did this and is there anything I should know? We plan on leaving the SQL 2000 database up during this process and granting read only at the time. I am nervous about this as this is a high profile database in our dept. I don't even know if I know where to begin! Any suggestions are truely welcome! Thanks, /P
We're upgrading a SQL Server 2000 cluster (Active/Passive) running on Windows 2003 Server 32 - bit Standard to a SQL Server 2005 Cluster running on Windows Server 2003 64-bit Enterprise. Our existent cluster's databases are residing on SAN. We can't purchase new hardware and we have no spare hardware. We also need to move from Windows 2003 32-bit Server to Windows 2003 64-bit Enterprise 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. Or should we just evict the passive node?
2. Install a fresh copy of windows 2003 64-bit server on one side along with SQL Server 2005. While this step is running, the active node would still be live on Windows 2003 32-bit Server and SQL Server 2000 serving our customers.
3. Bring the active server down.
4. Create new cluster on the newly upgraded server and assign the same cluster name and IP as the original one.
5 Bring the luns from SAN to the newly upgraded server and initialize SQL Upgrade
6. As a final step, the old active node will be rebuilt, we would install a fresh copy of windows 2003 64 - bit 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.
I'm upgrading MSSQL2000 (RTM) cluster to 2005. I haven't seen any information regarding a minimum service pack level for 2000. This upgrade just makes me overly caution.
Hi all, i am in the process of upgrading my clustered SQL 7 to a new cluster with SQL 2005.
I tried to run Upgrade advisor against the SQL 7 cluster but i am not able to make it work. I checked prerequisites on my client machine, checked if my account has administrator privileges on thew cluster and everything seem fine. I tried to run UA using node name, virtual server name (as suggested in the help), IP address (both node and virtual server ones) and even SQL 7 instance name (!) with no result.
Are there any issue about upgrade advisor against a SQL 7 cluster ? or am I missing something about Upgrade advisor??
i have created a new login in primary server and provided dbowner permission to primary db.how do i transfer this login to secondary server and assign the same permission to secondary db ?
When upgrading servicepack for SQL Server 7 in a Windows 2000 cluster, do I need to uncluster the servers before installing SP? Install on Node 1 first?
We have a simple two-node x86 failover cluster attached to a SAN on which SQL Server 2005 runs. We recently bought two new x64 boxes to upgrade the cluster. My original plan was to just add the new nodes to the existing cluster and then remove the old nodes from the cluster, but I just found out that you can't mix architecture types in a cluster.
So far, it seems our choices are:
1) Install x86 Windows 2003 Server on the new nodes, losing performance. 2) Make a new cluster and migrate the data, possibly imposing downtime.
I have a production failover cluster running SQL Server 2000 at SP3that I want to upgrade to SP4. I do not have a test failover clusterto test with so I need the install on the primary server to work thefirst time. Per the information I have I just install the patch on theprimary server and it will install both on the primary and on thesecondary.However, I remember when I did the initial install and it failed. Thefirst problem traced to the fact that the install uses temporary filesunder the profile of the installing administrator and the id had neverlogged into the second server so the install failed on creating thetemporary file. The was a second problem that related to an OS featurethat had to be off for the install to work.If anyone out there has done this upgrade and remembers encountering aproblem and its fix/workaround I would appreciate a head up warning.Thank you-- Mark D Powell --
when i install sql server 2005 in cluster. I have error at Setup process screen --> the selected components are being configured.all the components are failed.I am using domain account with administrator account privilege on both server.OS : windows server 2008 on virtual machine..when i install sql server agent is enable to select during setup..
I'm trying to do a SQL 2008 cluster installation.I installed one node and now I'm trying to add a failover cluster node.in the "add Node Rules" I get following message:
Rule Check Result...Rule "SQL Server Database Services feature state" failed.The SQL Server Database Services feature failed when it was initially installed. The feature must be removed before the current scenario can proceed.
i setup a 2 node sql cluster but 1433 is not listening. I check sql configuration manager and entered 1433 for all ip addresses restarted services but still not 1433
We have about a dozen SQL server 2000 Enterprise Edition servers in house. Our goal is to set up a cluster SQL server 2005 and consodiate the existing dozen servers to a few servers for easy manage and maintainence. So there are 3 things that we want to accomplish:
1. upgrade to SQL server 2005,
2. Consolidate existing servers
3. Make a cluster server to get high availability
But I'm sure what's the right order to acheive them. To upgrade each server to 2005 and then move them to cluster server? or set up the cluster server in 2005 and restore existing dbs to the cluster server. upgrade first or cluster first? upgrade first or consolidate first? pros and cons? upgrade or backup/restore? What do you recommend? We have lots of stored procedures, views and triggers, DTS packages and some replications. Any insight will be greatly appreciated.
I ran into problem while trying to install SQL Server 2008 to join to another node in a failover cluster ,you will find here the configuration doc and installation details. URL...
I have upgraded our test server and on non cluster production machine. My next server is a cluster and I don't have a test cluster server. Do I upgrade the active node and that is all or am I going to need to fail it over and upgrade the other node.
Also the prerequesite for the upgrade advisor is .net 2.0 I am going to up that on each server one at a time but I am only going to add the upgrade advisor to one node is that ok.
I read the SP1 documentation and it clearly states only patch the active node and do not patch the inactive nodes.
