SQL not caching on failed over node
Hi Friends,
Running SQL 2008 SP4 Cluster , but when I'm on second node the queries are extremely slow and noticed that the SQL is not caching properly the data after the first warmup run. any thoughts and suggestions? have you had this problem before?
Thanks,
Patrick

Hi Patrick,
According to your description, you face slow running queries. Based on my research, the issue could be due to the lack of useful statistics, or the lack of useful indexes according to this
article.
To trouble shoot the issue, you could follow the steps below:
1. Use SQL Server Profiler to find the slow queries. SQL Server Profiler provides a graphical user interface to create, manage, analyze, and replay SQL traces. SQL Server Profiler provides several built-in templates where tracked events and columns for each
event are defined. You could select TSQL_Duration from the templates, and select the save to file option to save the captured event information into a trace file (.trc) that you can analyze later, or replay in SQL Server Profiler. For how to monitor a query
using SQL Server Profiler, please refer to the article:
http://solutioncenter.apexsql.com/monitor-sql-server-queries-find-poor-performers-sql-server-profiler/
2. Analyze the performance of a slow-running query according to the following article:
Displaying Graphical Execution Plans (SQL Server Management Studio). The information gathered allows you to determine how a query is executed by the SQL Server query optimizer
and which indexes are being used. Using this information, you can determine if performance improvements can be made by changing the indexes on the tables. For more information about how to use indexes to improve query performance, see
General Index Design Guidelines.
3. You could create additional statistics, or update statistics. For more information about how to use statistics to improve query performance, please refer to the article:

License Probelm Fail over node.
Dear Gurus,
I am reciving an error while applying the liscense to the fail over server.
SAPLICENSE (Release 700) ERROR ***

My Production system no is 00000000031XXXXXXX but the license key is for 00000000031XYYYYY.
I am anot able to login to fail over node due to this.
How can I resolve this problem ?
Sachinsachin,
how r u applying the license through slicense???
unable to login in failover?? have u deleted the temporary license??? or has it crossed 4 weeks??
if u have deleted the temp license apply the license through visual admin
if it has crossed 4 weeks , revert the date backwards and apply license
u must have applied for a license in oss using other system with same sid,
u have to copy the system number from the node u have applied license on and apply for a license under the same system in the oss and give the system number.
when u get the license apply as mentioned above. -

Load balancing not happending but fail over is for Read only Entity beans
The following are the configuration.
Two NT servers with WL5.1 sp9 having only EJBs(Read only entity beans)
One Client with WL5.1 sp9 having servlet/java application as
EJB client.
I am trying to make a call like findbyprimarykey in one of the
entity bean. I could see the request is being directed only to the one of the
server always. When I bring that server, fail over is happening to the other server.
Here are the settings I have in the ejb-jar.xml :
<entity>
<ejb-name>device.StartHome</ejb-name>

SQL 2005 cluster rejects SQL logins when in failed over state
When SQL 2005 SP4 on Windows 2003 server cluster is failed over from Server_A to Server_B, it rejects all SQL Server logins. domain logins are OK. The message is "user is not associated with a trusted server connection", then the IP of the
client. This is error 18452. Anyone know how to fix this? They should work fine from both servers. We think this started just after installing SP4.
DaveKHello,
The connection string is good, you're definitely using sql auth.
LoginMode on Server_B is REG_DWORD 0x00000001 (1) LoginMode on Server_A is REG_DWORD 0x00000002 (2) Looks like you are on to something. I will schedule another test failover. I assume a 2 is mixed mode? If so, why would SQL allow two different modes
on each side of a cluster?
You definitely have a registry replication issue, or at the very least a registry that isn't in sync with the cluster. This could happen for various reasons, none of which we'll probably find out about now, but never the less...
A good test would be to set it to windows only on Node A, wait a minute and then set it to Windows Auth and see if that replicates the registry setting across nodes correctly - this is actually the windows level and doesn't have anything to do with SQL Server.
SQL Server reads this value from the registry and it is not stored inside any databases (read, nothing stored in the master database) as such it's a per machine setting. Since it's not set correctly on Node B, when SQL server starts up it correctly reads
that registry key and acts on it as it should. The culprit isn't SQL Server, it's Windows Clustering.
Hopefully this makes a little more sense now. You can actually just edit the registry setting to match Node A and fail over to B, everything should work correctly. It doesn't help you with a root cause analysis which definitely needs to be done as who knows
what else may not be correctly in sync.

Extension Mobility not working during fail over
Hello All
I am John. I have a cluster that has 2 subscribers and 1 publisher. We are running 8.5.1. Yesterday I had a case where my one subscriber had failed and everything failed over to the other subscriber. Everything but extension mobility seemed to work. I checked all my certs, I checked the services, I checked the url for the services. Everything seemed to check out correctly. The url is pointed to the publisher and the publisher was available.
What i saw during failover:
When the services button was activated I received the requesting notice. after a while the message changed to Host not found. Then the next message was select service.
I did a restart on the extension mobility service with no effect. The other web applications (such as corp directory) all seem to be working correctly. Extension Mobility is the only service I have running.
When the failover ended and my lost subscriber was available, extension mobility and the services started working again.
Any help or ideas would be greatly appreciated.
Thank you
JohnHi John,
As suggested by iptuser55, switch on the EM service on both the nodes. This is the only way failover would work. There are 2 services in CUCM, Extension Mobility and EMApp. The EMApp runs on all the nodes, and its job is to keep a list of the nodes with the EM service activated. When the top node in that list goes down, the EMApp will then point to the next node in the list, which will act as the Failover.
Here's the architecture of the EM service.

Weblogic 7.0 SP1 JDBC Multipooling does not appear to fail over consistantly
We are running Weblogic Platform 7.0 SP1 on a Sun with Solaris 8 O/S
We have a connection multipool set up associated with a Data Source.
The multipool has two connection pools, each pointing to a seperate but
Identical database. The multipool is created with the high availability algorithm
set.
both connection pools have the following settings:
(Connections Tab) (Testing Tab)
Initial Capacity:0 Test Table Name: dual
Maximum Capacity: 20 Test Reserved Connections: Checked
Capacity Increment: 2
Login Delay Seconds: 2
Refresh Period: 15
Allow Shrinking: Checked
Shrink Period: 15
When the first database goes down for a backup, We can see the exceptions thrown
from the
broken acitve connections, which would be expected. But we also notice a significant
response time increase (3-7 seconds) and we notice continuing exceptions from
what appears to be the application EJB still attempting to connect to the first
instance. It is only when a DISABLE_POOL is issued using the command line interface
to disable the first pool in the multipool that the response time drops to normal
and the exceptions stop. The exceptions don't happen for every query, but we cannot
understand why the test-on-reserve doesn't seem to always work.
Any help would be appreciatedThis is known behavior of the "high availability" algorithm for multipools.
Whenever a multipool is asked for a connection, it will always try the first pool first
(unless it has been diabled). The algorithm doesn't remember that it had trouble with
the first pool and start with the second pool (e.g., put the first pool at the end of the circular list
of pools to be tried). This is the way it was designed (in my opinion, this defies the
principal of least astonishment, but not everyone agrees with me).
We are planning to add a new algorithm in the next release that does keep state.
The way it currently works, it depends on how long it takes to figure out that
the first pool is not available. This depends on the database client driver and
the network connection (it could take from 100ms to multiple seconds to minutes
to figure it out).

Fail over is not happening in Weblogic JSP Server
Hi..
We have 6 Weblogic instances running as application server (EJB) and 4 Weblogic
instances running as web server (JSP). We have configured one cluster for EJB
servers and one cluster for JSP servers. In front-end we are using four Apache
servers to proxy the request to Weblogic JSP cluster. In my httpd.conf file I
have configured with the Weblogic cluster. I can see the requests are going in
all the servers and believe the cluster is working fine in terms of load balancing
(round-robin). The clients are accessing the servers using CSS (Cisco Load Balancer).
But when we test the fail-over in the cluster, we are facing problems. Let me
explain the scenarios of the fail-over test:
1. The load was generated by the Load Generator
2. When the load is there, we shut down one Apache server, even though there was
some failed transaction, immedialty the servers become stable. So fail-over is
happening in this stage.
3. When I shutdown one EJB instance, again after some failed transactions, the
transactions become stable
4. But, when I shutdown one JSP instance, immediately the transaction failed and
it is not able to fail over to another JSP server and the number of failed transactions
increased.
So I guess, there is some problem in the proxy plug-in configuration, so that
when I shutdown one JSP server, still the requests are being send to the JSP server
by the Apache proxy plug-in.
I have read various queries posted in the News Groups and found some information
about configuring session and cookie information in the Weblogic.xml file. Also
I’m not sure what are all the configurations needs to be done in the Weblogic.xml
and httpd.conf file. Kindly help me to resolve the problem. I would appreciate
your response.
===============================================================
My httpd.conf file plug-in configuration:

Dabase fail over problem after we change Concurrency Strategy:
Hi We had Concurrency Strategy:excusive . Now we change that to Database for performace
reasons. Since we change that now when we do oracle database fail over weblogic
6.1 does not detect database fail over and it need to be rebooted.
how we can resolve this ??Hi,
It is just faining one of the application servers, developer wrote that when installing CI, Local hostname is written in Database and SDM. We will have to do a Homogeneous system copy to change the name.
The problem is that I used Virtual SAP group name in CI and DI application servers, in SCS and ASCS we used Virtual hostnames and it is OK according to SAP developer.
The Start and instance profiles were checked and everything was fine, just the dispatcher from CI is having problems when comming from Node B to Node A.

Fail-over options for Standalone Print Server
Our organization recently set up 3 2012 r2 Print Servers to handle 3 separate sites. Each printer server contains only the printers within the site - which makes each server a standalone print server. I'm concern with the issue of not
having a fail-over plan in place, in the event one of my server should fail. Does anyone have any fail-over suggestions.Hi Thomas,
If we want to create a clustered printer server, we need to created another print server in the same site.

3 node cluster with 1 vInstance. vInstance can not to fail-over to one specific node.
I have a 3 node cluster all running Windows Server 2008 R2. Roughly once a month I see my vInstance become degraded and attempt to fail-over. Everything is good as long as it fail-over to SQL01 or SQL02. However if it attempts to fail-over to SQL03, it does
not come online
Quick resolution is to move it manually to SQL01 or SQL02. What could be causing it to fail every time on SQL03.
A couple points:
I did not build the environment.
I am not a DBA.
I only have general knowledge of SQL clustering.
I always get two EVENT ID's: 1069
Cluster resource 'SQL Server (VSQL04)' in clustered service or application 'SQL Server (VSQL04)' failed.
and then
EVENT ID 1205
The Cluster service failed to bring clustered service or application 'SQL Server (VSQL04)' 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.
Where should I begin to look for issues?Here is the cluster event prior to offline state. I will have to go check the cluster log.
The Cluster service failed to bring clustered service or application 'SQL Server (VSQL04)' 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.
i do not think this helps.. it just says..a resource in offline state.. you need to dig more and see which one it is and why it did not come banck on ..it should be mentioned in the log and\or event viewer.
Hope it Helps!! -

When I visit the S: drive in windows explorer and open the Shadow copy dialogue box, there are entries showing the times and dates of the shadow copies ran when on the original node. So the disk knows about the shadow copies that were ran on the
original node but the "previous versions" tab has no entries to display.
This is in a 2012 server (NOT R2 version).
Can anyone explain what might be the reason? Do I have an "issue" or is this by design?
All help apprecieated!

Please first check the requirements in following article:
Using Shadow Copies of Shared Folders in a server cluster
http://technet.microsoft.com/en-us/library/cc779378(v=ws.10).aspx
Cluster-managed shadow copies can only be created in a single quorum device cluster on a disk with a Physical Disk resource. In a single node cluster or majority node set cluster without a shared cluster disk, shadow copies can only be created and managed
locally.
You cannot enable Shadow Copies of Shared Folders for the quorum resource, although you can enable Shadow Copies of Shared Folders for a File Share resource.
The recurring scheduled task that generates volume shadow copies must run on the same node that currently owns the storage volume.
The cluster resource that manages the scheduled task must be able to fail over with the Physical Disk resource that manages the storage volume.

2 node Sun Cluster 3.2, resource groups not failing over.
Hello,
I am currently running two v490s connected to a 6540 Sun Storagetek array. After attempting to install the latest OS patches the cluster seems nearly destroyed. I backed out the patches and right now only one node can process the resource groups properly. The other node will appear to take over the Veritas disk groups but will not mount them automatically. I have been working on this for over a month and have learned alot and fixed alot of other issues that came up, but the cluster is just not working properly. Here is some output.
bash-3.00# clresourcegroup switch -n coins01 DataWatch-rg
clresourcegroup: (C776397) Request failed because node coins01 is not a potential primary for resource group DataWatch-rg. Ensure that when a zone is intended, it is explicitly specified by using the node:zonename format.
bash-3.00# clresourcegroup switch -z zcoins01 -n coins01 DataWatch-rg
clresourcegroup: (C298182) Cannot use node coins01:zcoins01 because it is not currently in the cluster membership.
clresourcegroup: (C916474) Request failed because none of the specified nodes are usable.

I am really at a loss here. Any help appreciated.
ThanksMy advice is to open a service call, provided you have a service contract with Oracle. There is much more information required to understand that specific configuration and to analyse the various log files. This is beyond what can be done in this forum.
From your description I can guess that you want to failover a resource group between non-global zones. And it looks like the zone coins01:zcoins01 is reported to not be in cluster membership.
Obviously node coins01 needs to be a cluster member. If it is reported as online and has joined the cluster, then you need to verify if the zone zcoins01 is really properly up and running.
Specifically you need to verify that it reached the multi-user milestone and all cluster related SMF services are running correctly (ie. verify "svcs -x" in the non-global zone).
You mention Veritas diskgroups. Note that VxVM diskgroups are handled in the global cluster level (ie. in the global zone). The VxVM diskgroup is not imported for a non-global zone. However, with SUNW.HAStoragePlus you can ensure that file systems on top of VxVM diskgroups can be mounted into a non-global zone. But again, more information would be required to see how you configued things and why they don't work as you expect it.

VIP is not failed over to surviving nodes in oracle 11.2.0.2 grid infra
Hi ,
It is a 8 node 11.2.0.2 grid infra.
While pulling both cables from public nic the VIP is not failed over to surviving nodes in 2 nodes but remainng nodes VIP is failed over to surviving node in the same cluster. Please help me on this.
If we will remove the power from these servers VIP is failed over to surviving nodes
Public nic's are in bonding.
