Oracle 8i in clustered environment

I have 2 Oracle 8.1.7.0 servers having a common RAID-5 device between them. The data actually resides on this device. The whole architecture is clustered based. There is an application server(s) & clients have to connect to this DB servers. The basic idea of this architecture is that in case of 1 server getting down, the other server automatically takes care of the application, without the application/clients knowing what happened.
Now, I cant understand how will the connection from the clients to the server be made. I mean, the Oracle Service name requires host name for connection. Which DB machine name should I give in this case? How will both the servers handle this? What will happen to the call from the clients? Anyone having idea of how to establish this scenario, kindly let me know asap.
Thanx,
Naeem

Quartz Scheduler in Oracle SOA 10g clustered environment

Hi,
I was able to successfully test the usage of Quartz scheduler in our Oracle SOA 10g dev environment. Our dev is single instance where as our Test and Prod are clustered. I would like to know if the scheduler works in clustered environment. I wasn't able to find any documentation specific to Quartz for Bpel. If it can be done can you provide some guidance.
I really appreciate your help
Jagan.

The schedulers do work on cluster environment. The trick is that every node has its oc4j containers, so you will need to deploy the scheduler process to every node in the cluster.
Suppose you have two nodes, and have a requirement to run certain process every two hours. You schedule the process in DEV environment to run every two hours. But in cluster you will specify to run every four hours on both the nodes. In simple explanation, node 1 will fire the process at 0,4,8, ... hours and node 2 will fire at 2, 6, 10, ... hours. So, the result is that your process is still running every two hours.
Hope this will help ...

Error when connecting to Oracle DataSource in a clustered environment

Trying to connect to a ORACLE 9.1 datasource in a remote clustered environment. Getting the following exception. The code works fine when connecting to a local non-clustered server. Any help will be greatly appreciated.

Issue in Synchronous File Read in clustered environment

Hi,
We are using clustered environment (4 managed servers) in Unix. In a OSB 11gR3 proxy service we are using Synchronous File Read. Randomly we are getting the below error. Let us know what could cause the issue. But the same code is working fine in a single stand-alone server configuration.

I face the same issue and I have given all permissions to the folder for OS user.
Because of this error my server is not starting up . Is there any way I can undeploy this composite to get my server running.
I cant do this from EM because SOA server is failing to start up.
I have tried removing it from $DOMAIN_HOME/deployed-composites but still when i try restarting the soa server the composite comes up there. Do we need to delete the entry some where else too. Kindly help.
Thanks,
Sri.

Upgrade 10G to 11.1.1.5 in Clustered environment

Question….can you use upgrade assistant in clustered environment?
Thanks!

You can only use the upgrade assistant to upgrade to a single instance Oracle BI 11g server. Typically this is a sandbox server environment or a VM that can simply be wiped clean after the upgrade. Then move the RPD,WebCat, etc. and AppRoles that get created during the upgrade process to a development server. The UA is looking for a single instance installation environment and that environment should be clean/fresh to avoid confusion and conflicts.
Please award points if helpful.

Jms is not working properly in clustered environment

Hi all,
i am using the application server oc4j 10.1.3.1.0 enterprise edition . my application is standalone application(thick client)
we are using the jndi.properties as follows ...
java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
java.naming.provider.url=opmn:ormi://172.16.1.38:6005:group/Security,opmn:ormi://172.16.1.38:6006:deceval_group/Security
java.naming.security.principal=oc4juser
java.naming.security.credentials=oc4juser
oracle.j2ee.rmi.loadBalance=lookup
we have two application servers in cluster topology as u can see above we have used one instance from one application server and one from another.
i have seen that for every instance there one jms server. at runtime it is taking one application servers services
say opmn port 6005 but when the application is connecting to the another application server say opmn 6006
here jms is not working properly when i send message
As we have clustered environment message must be propagated all the applications who use above jndi.properties.
if i keep use only one application server opmn say
java.naming.provider.url=opmn:ormi://172.16.1.38:6005:group/Security
then its is working excellently
please can u provide any solution ASAP
thanks in advance

FTP Adapter On in a Clustered Environment

Hi everyone,
I noticed that in a clustered environment (3 servers) an FTP Adapter using the “File Modification” feature to get files will get the file 3 times. Is there some configuration that can be done to stop that from happening?

Try adding Singleton property to adapter and set it as TRUE.
For reference check this blog - Mark's Blog: File Adapter in Oracle SOA 11g cluster environment

Deployment of BPEL (and ESB) into Clustered Environment

Hi All,
I was after any view points / pointers into peoples experiences into deployment of BPEL and ESB into a clustered Oracle iAS SOA suite environment, where there are two or more nodes running BPEL, ESB etc with a corresponding OHS Loan Balancers. I have been unable to find any specific information with regards to recommendations into the best ways to deploy into a clustered environment.
My viewpoints are there are two alternative approaches that could be used, both of which use ANT deployment scripts to register / deploy the various services.
(1) Leaving all nodes up in the cluster and using a properties file to specify the relevant details, deploy to one environment allowing the load balancer to distribute the software to the respective nodes in the cluster
(2) Deploy to each of the nodes in turn ensuring all other nodes in the cluster are taken down during each separate deployment
What are other peoples thoughts / experiences / recommendations?
Thanks in Advance
Dave

I don't believe there is any real information on deployments in a cluster in those documents.
There is a note on metalink 457654.1 which says to apply to each node, while doing this shut down the other servers. From experience this worked for some configuration and not others.
Can you say what cluster deployment you used, e.g. 10.1.3.1 or 10.1.3.3 with BPEL and ESB-RT in the same oc4j?
Also what version are you on. If you are on 10.1.3.4 using the 10.1.3.3 deployment configuration you don't need to shutdown the nodes. And you can get away with just deploying to one node but make sure your <ORACLE_HOME>/bpel/system/config/collaxa-config.xml file has been set to cluster = true. Look at metalink note 746251.1.
You can experience the notorious Process Lock Timeout Error when not shutdown cleanly but this is resolved using the best practice guide http://www.oracle.com/technology/tech/soa/soa-suite-best-practices/soa_best_practices_1013x_drop1.pdf
ESB can be applied to just one node.
Make sure that all your endpoints are pointing to the load balancer and not the actual node themselves.
Also you connect string is different in your build.properties make sure of the following
cluster = true
oc4jinstancename = default_group
local.oc4jinstancename = oc4j_soa (or the oc4j container with BPEL)
esb
deployer.uri=deployer:cluster:opmn://hostname:opmn port/default_group

Error in Server log of one of the server on the clustered environment(OBI)

Hi
We had setup Clustered Environment and when we are trying to log in on to the Primary Server which is also Primary Controller, everything is fine on front end but we had faced the following error in the server log as follows : "[46036] Internal Assertion: Condition m_hFile != hFileNull, file .\Src\mfcfile.cpp, line 447."
Please provide help by letting me know what this error mean and how can we avoid this error.

What happens if you disable your master BI server, do you get the error in the other BI Server log when you login to Presentation Services?
The message is an internal error, you need to raise an SR with Oracle to determine why it's happening and how to prevent it.

Shutdown Oracle Database in MSCS Environment

Dear All,
We are facing problem regarding shutdown the oracle database in Cluster Environment. We have installed SAP HA on windows 2003 server and backend database is Oracle.
In order to configure the dataguard we have to create the control file from Primary Database for this purpose we have to shutdown and then startup the database in mount state.
But whenever i shutdown the database from SQL prompt by "shutdown immediate" command and see the status of
database it always remains in open state.
I have tried the following options as well but no success:-
Stop all the instances of SAP and then shutdown the database.
Shutdown the second node and then shutdown the database.
Brought offline the ORACLE<SID> group and then shutdown the database.

ORA-12560: TNS:protocol adapter error"
The above error message comes if Oracle Listener service is not running. Start Oracle TNS Listener service, if it is not running.
You can create control file while your Primary Database is ONLINE. Use the below mentioned command to create standby control file and use it for recovery at Standby database.
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/to/controlfile.ctl';
If you want to Start/Stop SAP/ORACLE in MCSC environment then refer the steps mentioned in these threads, [thread1|Re: how to start/stop a MSCS clustered SAP system?; and [thread2|Stop sap and oracle on MSCS;.

AIA FP 2.4 on SOA suit 10.3.1.4 clustered environment

Hi
I am trying to install the FP on top of my SOA 10.1.3.4 MLR5. This is a clustered environment.
As described, one should install the FP with ant on the admin member, with ant --noconfig FPInstall.xml
But it keeps failng at deploy AIAReadJMSNotificationProcess with ORABPEL-12529
It says it misses some adapters :
AdapterFrameworkImpl::endpointActivation - Endpoint Activation Error.
The Resource Adapter was unable to activate the endpoint :{} due to the following reason: ORABPEL-12529
ManagedConnectionFactory problem.
Could not instantiate ManagedConnectionFactory oracle.tip.adapter.jms.JmsManagedConnectionFactory due to:
Missing class: oracle.tip.adapter.jms.JmsManagedConnectionFactory
Dependent class: oracle.tip.adapter.fw.wsdl.WSDLUtils
Loader: oracle.bpel.common:10.1.3
Code-Source: /opt/oracle/product/10.1.3/assoa/bpel/lib/orabpel.jar
Configuration: <code-source> in /opt/oracle/product/10.1.3/assoa/j2ee/oc4j_soa/config/server.xml
This load was initiated at orabpel.root:0.0.0 using the Class.forName() method.
The missing class is not available from any code-source or loader in the system.
Please make sure the corresponding JCA Resource Adapter has been deployed.
Please correct the reported issue and redeploy the BPEL process.
These adapters are installed in the oc4j_esbdt as the install guide on soa clustering describes, and I think the deployment expects it to be in the oc4j_soa. Am I right? Does anyone know how to overcome these issues?
kind regrds
Michel

Hi Michel,
I found the solution myself
Just manually deploy the adapters in oc4j_soa the same as in oc4j_esbdt, now deployment goes ok.
Please excuse my ignorance. How do you manually deploy the adapters as mentioned above? Please give the details.
Thanks,
Amorsolo

SAP Adapter Best Practice Question for Deployment to Clustered Environment

I have a best practices question on the iway Adapters around deployment into a clustered environment.
According to the documentation, you are supposed to run the installer on both nodes in the cluster but configure on just the first node. See below:
Install Oracle Application Adapters 11g Release 1 (11.1.1.3.0) on both machines.
Configure a J2CA configuration as a database repository on the first machine.
Perform the required changes to the ra.xml and weblogic-ra.xml files before deployment.
This makes sense to me because once you deploy the adapter rar in the next step it the appropriate rar will get staged and deployed on both nodes in the cluster.
What is the best practice for the 3rdParty adapter directory on the second node? The installer lays it down with the adapter rar and all. Since we only configure the adapter on node 1, the directory on node 2 will remain with the default installation files/values not the configured ones. Is it best practice to copy node 1's 3rdParty directory to node 2 once configured? If we leave node 2 with the default files/values, I suspect this will lead to confusion to someone later on who is troubleshooting because it will appear it was never configured correctly.
What do folks typically do in this situation? Obviously everything works to leave it as is, but it seems strange to have the two nodes differ.

What is the version of operating system. If you are any OS version lower than Windows 2012 then you need to add one more voter for quorum.

WebLogic 10.3.4 Adminserver Performance Issues - Clustered Environment.

I am running WL 10.3.4 64 bit version on 64 bit hardware (blade serves) running Solaris 10 and I have the servers setup in a cluster. There are 3 machines are part of the cluster.
Managed Server1 is on Blade Server 1
Managed Server2 is on Blade Server 2
Managed Server3 is on Blade Server 3
We have about 20 different clusters setup and 60 servers across those 20 clusters.
The adminserver runs on a separate box (not a blade server). Tasks that do NOT involve the servers or deployments tabs are relatively fast however, when I go to the servers or deployments tab, and to some extent the clusters tab, the response is very slow.
For example, I am running WL 10.3.0 on less robust hardware. I installed the patch that Oracle published to resolve this particular issue. We have a similar number of clusters and servers on in that environment (3 severs to a cluster). The servers tab responds in 10 seconds.
In WL 10.3.4, the servers and deployments tabs take about 45 - 60 seconds to respond. This adds a LOT of overhead to doing any server or deployment related tasks.
I realize that the admin server has to query all the managed servers but performance in 10.3.4 is much worse than WL 10.3.0 with the performance patch.
Has anyone else run into similar performance issues with the WL 10.3.4 ADMIN Console running in a clustered environment? If so, does anyone have any suggestions to help improve performance.
I also run a WL 10.3.4 instance in a single server environment and the servers and deployments tabs respond withing 10 seconds (very fast). It is just in a clustered environment.
Regards,
Mark

hi Mark, it's a very interesting story, any follow-up? I would be curious to know the reason for the delay...

DbControl not working in clustered environment

Hi all,
I have a situation here with Oracle dbcontrol -it is not working in clustered environment. It is working on one node but fails on other node. Any suggestions ?
Thanks in advance !

http://download.oracle.com/docs/cd/B28359_01/server.111/b28319/emca.htm
in this article Oracle has given example with RAC. so thats why i asked that question.Exactly, with RAC. If you specify -cluster option, you should have a running cluster, isn't it ?

Admin server in clustered environment

Hi,
In OBIEE 11g Clustered environment, we will have admin server and multiple managed servers(say 2) and OBIEE components running on both machines(some are active-active and some are active-passive). So if i have 2 servers say A and B, Do i need to start the Admin servers on both the machines or just on primary server A?
If not then primary server will have 1 Admin server and 1 managed server along with OBIEE components and secondary server will have managed server and OBIEE components right?
Thanks,
RM

The managed services will continue to run while trying to connect with the admin server. Hence if Admin Server A goes down, it does not mean the managed services will not continue to function.
Link: http://docs.oracle.com/cd/E14571_01/web.1111/e13716/understand_domains.htm
Look for "what happens when if the Administration Server fails?"
I will have to get back on if Admin Server B needs to be manually started up or if it can be automated as part of HA.
I know the managed server can also be configured such that it can function as the Admin server. I have found a similar discussion on the followin thread surrounding 11.1.1.5: obiee 11g enterprise deployment
Mark if helps.
