Duplicate Instances are coming on Active- Active Cluster

Hi,
I am using FileAdapter on a shared drive in Active-Active cluster.
I have done all Oracle Recommended settings(e.g. eis/HAFileAdapter).
Also I would just like to mention that , I have not used below property for my Active Active cluster.
"<property name="singleton">true</property>"
I am getting a strange issue of duplicate processing of same file.
Some times I can see 2-3 instances with the same details and some time it will work normally and I will see only one instance.
I am not able to find out the reason for that.
Any pointers are suggestions would be appreciated ?
Thanks,
Ashu

You have to have ClusterGroupId to make one node active and another inactive in composite.xml file.
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" partnerLink="ReadFileContent">
<property name="portType">Read_ptt</property>
*<property name="clusterGroupId">ReadFileCluster</property>* </activationAgent>
</activationAgents>
Thanks,
Vijay

SCOM 2012 - How does SQL MP "know" which instances are available and active?

Using SCOM 2012 R2 with Microsoft's SQL MP 6.5.1.
Getting alerts occasionally for issues with SQL instances which are later found to be not active any more or removed from the SQL server.
Can someone explain how the MP determines which SQL instances are available? Is it a matter of simply reading folder structures on the various mount points, reading registry? Much appreciated for any tips.

SCOM SQL MP will using discovery to discovery SQL instance. Once the SQL instance is discovery, the SQL instance object persist in the database even though the SQL instance is removed.
Solution:
To clean up the objects you can run the Remove-SCOMDisabledClassInstance Powershell cmdlet. Then all the relationships that involve objects related to a disabled discovery is deleted.

Duplicate emails are coming through Ibots. Can you any help how to resolve

One of our user is receving Duplicate emails through Ibots for scheduled reports.
I am not fully aware of Ibots. Can any one help me how to resolve this.
Thanks

I'd imagine that email address is being picked up twice, be it as a delivery profile against two different users, or the ibot is being sent to a group they belong to AND them directly (or two groups they belong to).

Active-Active cluster, duplicate instances?

Hi,
We have a active-active cluster and we get all instances as double amount. All adapter db, ftp etc. Like we read file using ftp-adapter and it creates two instances from one file? What is problem in our environment?

add signletone property for the services(ftp adapter in composite.xml)
<property name ="singleton">true</property>
e.g.
<service name="WSS" ui:wsdlLocation="WSS.wsdl">
<interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/ftp/Application2/XX_GLMaintain/WSS#wsdl.interface(Get_ptt)"/>
<binding.jca config="WSS_ftp.jca"/>
<property name ="singleton">true</property>
</service>
and also
<property name="activationAgent.WSS_SAP.className" type="xs:string"
many="false">oracle.tip.adapter.fw.agent.jca.JCAActivationAgent</property>
<property name="activationAgent.WSS_SAP.portType" type="xs:string"
many="false">Get_ptt</property>
e.g.
<component name="XX_GLMaintain">
<implementation.bpel src="XX_GLMaintain.bpel"/>
<property name="activationAgent.WSS_SAP.className" type="xs:string"
many="false">oracle.tip.adapter.fw.agent.jca.JCAActivationAgent</property>

FTP Adapter duplicate processing of files in Active-Active cluster env

Hi All,
We have single active-active cluster environment and we have configured all the HA configurations for Inbound and Outbound operations (except outboundDatasourceLocal). But we faced a situation that the FTP Adapter processed a file twice. This happened when there was a fail-over in oracle database in where SOA-INFRA schema is created.
Please let me know if anyone faced similar issue and what would be the resolution for this duplication issue.
Thanks in Advance.

Hi Vernetto,
Thanks for your reply.
I too had opened a ticket with oracle and they are looking into the issue.
can you please let me know what are the inbound and outbound operation configurations you have specified in the 'outbound connection pools'. Also is there any other specific property you set in jca file?
one more thing is, we have configured outboundLockTypeForWrite to 'oracle' as we are using the oracle database. but i couldnt see any data in FILEADAPTER_IN or in FILEADAPTER_MUTEX tables. you said you could see data in FILEADAPTER_IN table. so is there any specific property requires to be set which i am missing?
please suggest.
Thanks.

How can we achive active/active cluster setup with Oracle

Hi Experts,
How can we achieve active/active database setup with oracle WITHOUT USING RAC.. As far as I know it's impossible (unless I'm wrong)..
We are using Oracle 11.2.0.1 64bit on Windows 2008 server. We deployed Oracle FailSafe but that's more of an active/passive solution based on a windows cluster.
The other solution we were thinking about is to use DataGuard and replication.. two servers.. the oracle instance running on one server generating logs, and the other server receive the logs and apply them to the physical standby db.. Still, this is not a real active/active setup.
So, is it possible to run 2 servers in an active/active cluster and have the oracle database in an active/active setup or have the instance running on multiple nodes (at the same time)?
Thanks

Let me give you a brief explanation of what the situation is and you can be the judge..
My client have four databases with the smallest one being 20GB and the biggest around the 35gb (SGA 750mb to 1.4gb (Tiny by DB standards) and probably on a normal day, you can run all four of them on a decent desktop).. The DBs are used to keep track of people information. Through out the year, the databases are almost sitting idle, and by idle I mean, the odd update here and there, the odd report..etc. No hard real processing of any sort. Two days of the year (end of year) we have all the operators consolidating records and what's not and they will be pounding away entering data and updating the tables - with hourly reports that goes to 3rd parties. The client expects a 99.99 up time and availability during those 2 days.
Now, tell me, How can I justify using RAC and spending hundreds of thousands of dollars in licensing and what ever extra costs introduced by the complexity of the environment for the above scenario knowing that I don't have any real use for RAC for 363 days of the year; and we MIGHT need it for 2 days of the year? This is the dilemma we're facing.
Thanks

Hello Sonia,
Can you ask your network team to monitor the traffic between primary and virtual host when you try to start java i.e STARTING_APP as it tries for 20mins and stopped.
I had the similar issue but with App server.Its almost the similar condition.Our network team managed to open some ports and removed the firewall.
After that issue got resolved..
Hope it helps

Hi Sunny,
You are correct,but we have a different strategy.
We will have CI as SPOF and no CI with DI as non SPOF on two nodes.
CI will be a part of cluster in compensation to the CI and DI as non-clustered on seperate nodes.
I am yet stuck on 27 th phase of CI installation.
I do not think that can be a cause of the error as we have gone through the phase of installing /confguring Java Engine and installing S/WUnits prior to this 27 th phasei.e "Prepeare to install minimal configuration" .
Anyways CI can always be a part of cluster as and HA option too.
Thanks for your reply.
Any futher suggestions is appreciated.
Thanks

Active active cluster

Dear all,
I'm trying to figure out without any success in the official documentation wether SQL Server 2012/2014 supports active-active clustering or not.
I mean by active-active clustering having two RDBMS accessing the same database in a read-write fashion at the same time (like an Oracle RAC).
Do you have any clues concerning this question ? Any pointer to an official documentation saying something like: "yes, you can make load balancing in front of an SQL server cluster" (or the negation ;) )
Thank you,
Laurent

I'm trying to figure out without any success in the official documentation wether SQL Server 2012/2014 supports active-active clustering or not.
Hi,
Let me first tell you there is nothing like Active active cluster correct word is Multi instance cluster. Multi instance cluster is fully supported in SQL Server.
I mean by active-active clustering having two RDBMS accessing the same database in a read-write fashion at the same time (like an Oracle RAC).
No multi instance cluster would be two or more applications accessing different instances of SQL server whih are residing on different or same nodes. Generally its different nodes. Oracle RAC is different from SQL Server clustering please dont mix both
to an official documentation saying something like: "yes, you can make load balancing in front of an SQL server cluster" (or the negation ;) )
Load balancing is Application concept and SQL Server Clustering is totally different from it. As a fact SQL Server clustering does not provides load balancing it provides redundancy. Installing multi instance cluster is same as Active passive cluster you
just need to install two instances with both instances on different node.
Please mark this reply as answer if it solved your issue or vote as helpful if it helped so that other forum members can benefit from it

Install SSAS and SQL on an Active-Active Cluster

Hello
I have to install SQL 2014 and SSAS on a 2-node FCI and I'd like to have SQL running on one node and SSAS on the other one so I can accomplish an Active-Active Cluster.
Is there any ste-by-step guide to do this?

Yes, you can have SQL Service running on one node and SSAS running on another node. In the truest sense its never active-active. But if you consider both nodes are active with different services rather than just staying passive then its fine.
Just that you install each of these in two different groups.
Find the step by step tutorial for SQL Service.

SQL Server 2008 Active/Active Cluster in sap

Dear Experts,
We are planning to install Active/Active Cluster in SQL server 2008 for SAP. Our landscape is with two servers. We needed the answers for the queries?
1. How we have to configure SAN storage hard disks?
2. How man disks needed for Active/Active cluster?
3. Is there any documentation available with screenshots?
Regards
Prathish Philip

Dear Bala,
First, don't give new name to someone. I would prefer Balmukund.
We are new to cluster, So we are not aware what is the requirements? Our SAN team(EMC2) will do the configuration in SAN, But we have to give the requirement as how many disks should be shared for each servers etc.......Our requirement is as below.
for optimal performance of SQL, you would be in better position if one drive is given to each file. SAP should have guidelines on the same as it's their product and they would known their IO requirement better.
We have two servers and we will install SAP on both servers, If first server is down the second server has to automatically take care the application without down time( as per our knowledge we think this is Active/Active cluster).
This confuses me. You need to check how many SQL Instances they are looking it? Active/Active (I hate you use this term) normally stands for two SQL instances running on two separate nodes. There is nothing shared between them. Uri has explained it in best
possible way.

Create mirror on active active cluster

have you tried this before?
on active active cluster, one instance ins1, another instance ins2, they are on same cluster. On ins1, create a database called pridb. Can I create one mirror on another instance ins2? what will happened if failover happened in ins1? Any other issue/concerns?
Thanks,
SkyRiver

Unable to failover the services in active-active cluster node

Hi,
i am applying the sp2 patch for sql server 2008 r2 in active-active cluster, we have 3 services in the cluster , node 1 as 2 prefered owner and node 2 as 1 prefered owner, when i try to move the service from node 2 to node1 , i am getting the below errors
DCOM was unable to communicate with the computer XXXXXXXXX using any of the configured protocols.
The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server XXXXXXXXX. The target name used was RPCSS/XXXXXX. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal
name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target service is using
a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC are both updated to use the current password. If the server
name is not fully qualified, and the target domain (XXXXXX) is different from the client domain (XXXXXXX), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.
The Cluster service failed to bring clustered service or application 'CHCROCHC045' 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.
Cluster resource 'SQL Server (CHCROCHC045)' in clustered service or application 'CHCROCHC045' failed.
any inputs appreciated to resolve this issue as i could not procedd with patching

Hi PGR,
As the issue is more related to Windows Server, I would like to recommend you post the issue in the
Windows Server forums for better support.
In addition, below are some article about troubleshooting error ” DCOM was unable to communicate with the computer XXXXXXXXX using any of the configured protocols” for your reference.
Event ID 10009 — COM Remote Service Availability
How to troubleshoot DCOM 10009 error logged in system event?

Error coming while activating ODS

Hi,
While loading data in datasource there is a field item text in which a small box is coming due to which error is coming while activating ODS. When i check line item of datasource it shows me '#' instead of that box.
So i wrote a code in ECC to remove special characters. But still it is not deleting that small box and sending me error in ODS.
The data comes same in the table also with that small box.
Please tell me how to solve that problem as i cant do it manually as there are a lot of records. Do tell me how to remove it.
Roma

Hi Roma,
Actually all the invalid characters in the error message are displayed by small square box only. So you might not get which actual character it is.
Check the below given article for removing special character. In this article they have mentioned one standard FM to remove the characters which you can use in update rule or transformation for filtering invalid characters.
