Backups in a cluster environment?

What do the rest of you do for backups in clustered environments? You can backup the cluster level configuration very easily but if you have a failure you need a machine level backup. Do you take the time to remove the machines from the cluster to get a good machine level backup?
Anyone know what the best practice is for this or what is your procedure?
Long live the NATION!

excellent questions.
i think the goal of a "cluster" concept is to have a no-backups-necessary kind of virtual configuration floating around in the ether. of course if you are making lots of machine level changes, then it's not practical to forgo individual backups.
temporarily removing machines and rejoining them shouldn't be too difficult, although you would want to probably suspend listeners and bring it offline for a few minutes:
1. temporarily remove the machine:
> clusterconfig removemachine
2. save configs via either email or local storage:
> saveconfig yes
> mailconfig yes
3. rejoin machine
> clusterconfig join [--port=xx]
important to note is that using 'mailconfig' or 'saveconfig' on a clustered box does give you everything you need, you just can't manually import it again as-is with 'loadconfig'. maybe it'd be easier to just do mailconfig from all appliances and parse out the machine level stuff in the XML config files???
i'd like to hear any other suggestions on how to pull this stuff out though! i'm sure there are some good ones!

SAP R/3 4.7 SR1 Migration to MSCS cluster environment

Hi all,
We are planning to move our existing standalone server R/3 production server to cluster environment.
I have some queries regarding this migration
Our R/3 system is running on SAP R/3 4.7x1.10 SR1 on Windows 2003 and Oracle 9.2
1. Central Instance has to be installed in local disk or shared disk
2. Is it correct to R3load procedures to export data from old server and import during Database installation
3. Presently our server is running with kernel 640, but for the new installation kernel will be 620. So when can i upgrade kernel immediately after central instance installation or after CI and DB Instance installation.
Give me some inputs
Thanks & Regards
KT

Hi, the best place for your questions would have been the forum SAP on Windows.
However, here the answers.
1) CI must be on a shared disk
2) Right, if you don't change the database platform and its release you can also use backup/restore
3) Right. You can also perform the installation with the latest NW04 installation master

TimesTen database in Sun Cluster environment

Hi,
Currently we have our application together with the TimesTen database installed at the customer on two different nodes (running on Sun Solaris 10). The second node acts as a backup to provide failover functionality, although right now only manual failover is supported.
We are now looking into a hot-standby / high availability solution using Sun Cluster software. As understood from the documentation, applications can be 'plugged-in' to the Sun Cluster using Agents to monitor the application. Sun Cluster Agents should be already available for certain applications such as:
# MySQL
# Oracle 9i, 10g (HA and RAC)
# Oracle 9iAS Application Server
# PostgreSQL
(See http://www.sun.com/software/solaris/cluster/faq.jsp#q_19)
Our question is whether Sun Cluster Agents are already (freely) available for TimesTen? If so, where to find them. If not, should we write a specific Agent separately for TimesTen or handle database problems from the application.
Does someone have any experience using TimesTen in a Sun Cluster environment?
Thanks in advance!

Yes, we use 2-way replication, but we don't use cache connect. The replication is created like this on both servers:
create replication MYDB.REPSCHEME
element SERVER01_DS datastore
master MYDB on "SERVER01_REP"
transmit nondurable
subscriber MYDB on "SERVER02_REP"
element SERVER02_DS datastore
master MYDB on "SERVER02_REP"
transmit nondurable
subscriber MYDB on "SERVER01_REP"
store MYDB on "SERVER01_REP"
port 16004
failthreshold 500
store MYDB on "SERVER02_REP"
port 16004
failthreshold 500
The application runs on SERVER01 and is standby on SERVER02. If an invalid state is detected in the application, the application on SERVER01 is stopped and the application on SERVER02 is started.
In addition to this, we want to fail over if the database on the SERVER01 is in invalid state. What should we have monitored by the Clustering Agent to detect an invalid state in TT?

SBO Mailer in a cluster environment

Hi,
I am currently facing an issue where when I install SBO Mailer on a cluster environment, the installation removes applications and license manager for some reason gets uninstalled.. When I want to uninstall the SBO Mailer, I do not see it under the Control Panel and neither do I see it in running in services. But if i look at the Service Manager the SBO Mailer Service is running.
The strange part is that after this installation, there is an add-on that stopped working.
Has anyone come across such a scenario?

Hi,
To uninstall you have to first run the Server tools and there you can uncheck the sbo mailer. There is not way you can uninstall SBO mailer service and you cannot find it under control panel its a service...not an applicaiton.
Run the server tools and then choose repair.

Deploying Java Web Application (WAR-File) into a cluster environment

Hi,
we have a web application which has to read from and write to the file system.
Since a short time we have a cluster environment (2 parallel servers) and since thisa time we have the problem, that files are worked double in the cluster. The application is working on both servers now and so we have this problem.
Does anybody know how we have to deploy the application correctly in a cluster environment or do we have to change anything in our source code of the application?
I didn't find any documentation about this.
At the moment we have deployed the application on one of the two servers only, but I think there must be a better way to solve this problem.
Thanks for your replies.
Regards
Thorsten

Hi,
I think first you need to wrap it into an EAR file, then you can deploy it.
As far as I know standalone deployment of WAR is deprecated as of 640.

PI 7.1 in a cluster environment (multiple ip-adresses): P4 port

We want to install PI 7.1 on unix in a cluster environment.Therefore we installed also DEV+QA with virtual hostnames like the prodsystem, which will be later installed.
At all sapinst installation screens we have used only the virtual hostname <virtual-hostname-server interface>.We have also set the SAPINST_USE_HOSTNAME=<virtual-hostname-server interface>. Although the P4-port seems to have used the physical hostname: in step 57 of sapinst we got problems and in dev_icm were:
[Thr 05] *** ERROR => client with this banner already exists:
1:<physical-hostname>:35644 {000306f5} [p4_plg_mt.c 2495]
After we have set
icm/server_port_1 = PROT=P4,PORT=5$$04, HOST=<virtual-hostname-server interface>
icm/server_port_6 = PROT=P4,PORT=5$$04, HOST=<virtual-hostname-user interface>
icm/server_port_7 = PROT=P4,PORT=5$$04, HOST=<physical hostname>
icm/server_port_8 = PROT=P4,PORT=5$$04, HOST=127.0.0.1
the sapinst was successfull.
Now we're not sure how to set these P4-parameters in our future productive cluster environment.
Our productive system PX1 will live in a HA environment, so we don't want to use the physical hostnames in any profile.
Our environment will look like:
HOST-A (<physical-hostname-A>):
<virtual-hostname-server interface>
<virtual-hostname-user interface>
HOST-B (<physical-hostname-B>):
Normally our prodsystem will live on Host-A (physical-hostname-A). All parameters should
only take the virtual hostname <virtual-hostname-server-interface>. During switchover the
virtual hostnames (server and user interface) will be taken over to HOST-B, while the physical
hostnames of HOST-A and HOST-B will stay like there are.
How do the parameters have to be set here ?
Have also the physical hostnames of both cluster nodes set in the
instance profile, e.g:
icm/server_port_1 = PROT=P4,PORT=5$$04, HOST=<virtual-hostname-server interface>
icm/server_port_6 = PROT=P4,PORT=5$$04, HOST=<virtual-hostname-user interface>
icm/server_port_7 = PROT=P4,PORT=5$$04, HOST=<physical-hostname-A>
icm/server_port_8 = PROT=P4,PORT=5$$04, HOST=<physical-hostname-B>
icm/server_port_9 = PROT=P4,PORT=5$$04, HOST=<localhost>
Any recommendations ? In note 1158626 is some infomation regarding P4 ports with multiple network interfaces, but it's not 100% clear for us.
Best regards,
Uta

Hi Uta!
Obviously we are the only human beings in the SAP community having this problem. Nevertheless let's give it another try with a - hopefully - more simple problem description (and maybe it will be helpful to copy and paste this description into the open SAP CSN also).
So here comes the scenario:
We have one physical host:
Physical hostname: physhost
Physical IP address: 1.1.1.1
On this physical host there is running one OS: SUN Solaris 10/SPARC
On top of this we have two virtual hosts where we install 2 completely independent PI 7.1 instances with separate virtual hostnames and separate virtual IP addresses and separate DB2 9.1 databases. That is this is not an MCOD installation.
Virtual Host no. 1 is PI 7.1 Development System:
Virtual hostname: virthostdev
Virtual IP address: 2.2.2.2
Java Port numbers: 512xx
Virtual Host no. 2 is PI 7.1 QA System:
Virtual hostname: virthostqa
Virtual IP address: 3.3.3.3
Java Port numbers: 522xx
With this constellation we face serious problems with the P4 port. Currently for example the JSPM for virthostdev does not start, because JSPM cannot connect to the P4 port.
In SAP note 1158626 we have learned that by default always the physical hostname/IP address is used to address the P4 port and that we have to configure instance profile parameter icm/server_port_xx to avoid this.
So how do we have to configure the instance profile parameter icm/server_port_xx for both systems to resolve these P4 port conflicts?
Additionally: Is it important to use distinct server port slot numbers xx in both systems?
Additionally: Is it possible to configure this parameter with hostnames instead of using IP addresses?
So far we have tried several combinations, but with each combination at least one or even both systems have problems with that f.... P4 port.
Please help! Thanx a lot in advance!

Volker

How to setup the cluster environment for BPM using weblogic

want to setup the cluster environment for BPM using weblogic....
i have installed the oracle weblogic server 10gr3 and oracle BPM enterprise for weblogic 10gR3
i have used the Admin tools from the "oracle BPM enterprise for weblogic" to setup the configuration and create the weblogic domain servers.
i can launch the process administrator and import the project exp file to domain server.
but what should i do to setup cluster environment using weblogic?
what i want to do is :
setup one admin machine..
setup two product machine..
enable the cluster so the admin machine can monitor the status of the product machine..
thanks a lot ...

The install guide at http://download-llnw.oracle.com/docs/cd/E13154_01/bpm/docs65/config_guide/index.html gives a reasonable amount of info on how to do this.
Personally I have not used the OBPM option to configure WebLogic instead I've used the information in the above install guide to create the weblogic domain in advance of configuring OBPM.
Once you've setup WebLogic configure OBPM using the values I mention in the following thread: How to set the JMX Engine parameter in Process Administation?
Let me know any specific config questions and I'll do my best to answer them for you.
Thanks,
Mike

Changing the listener port number in a cluster environment

Hello,
I have an Oracle 10g database on a Windows cluster environment with Oracle Fail safe. I am trying to change the default listener port number - these are the steps I have done to change the port number:
1) Take the listener offline via Oracle Fail safe
2) stop the original listener from the command line
3) change the port number in the listener.ora file & save
4) start the original listener
5) bring the listener online in Fail safe
6) register the listener in the database with ALTER SYSTEM SET LOCAL_LISTENER....
After all this, when i check the status of the listener via lsnrctl, i see that the new port number is used, however in the Fail safe administrator, I still see the default port 1521. How do I go about changing the port number so that Fail safe also registers the change?

I did troubleshooting to verify the group, but this just changed the port number back to the default in the listener.ora & tnsnames.ora.
So I did all the steps again to change the port number from the default to another - via lsnrctl status, i see that the new port number is being used, I can also log in to the database via Toad using the new port number, in v$parameter i see that the local_listener is registered on the new port number....only under the Fail Safe manager, the port number (under listener parameter) has not changed....it still shows the default port number. Anyone know how to change this???

Installation of CRM 2007 in Windows with oracle and cluster environment

Dear Experts,
We are about to start the installation of CRM 2007 (ABAP+JAVA) with
Oracle 10g on Windows x64 in cluster environment. In the SAPINST dialog
box under High availability option, I could see installation options like ASCS
Instance, SCS Instance, First MSCS node, Database Instance, Additional
MSCS Node, Enqueue Replication Server, Central Instance and Dialog
Instance.
I have gone through the installation guide. I have below queries
regarding the same. Can you please clarify the same
1) Our requirement is we want to have an ACTIVE-ACTIVE cluster setup
with sap service running in Node A and Database running in Node B. Can
we have this setup in ABAP+JAVA setup
2) Also,in the SAPINST dialog box as said above except last two
(Central and Dialoge instance) as per standard installation guide are
to be installed in shared drives as per the requirement. But, central
and dialog are said to be installed locally on any one node in MSCS or
in separate server. As per my understanding Dialog instance will be
used for load balancing which we do not require now. Hence I feel this
is optional in our case. Where as Central Instance I am not able to
understand why this option is for? Is it mandatory to be installed or optional. If
so, when I installed it in one of the MSCS node the incase of failover
how does it effect the system. As per my understanding ASCS and SCS
comprise central instance.
Please clarify and thanks in advance.

Sharath Babu M

I am following as per the standard installation guide.

How to Process Files in Cluster Environment

Hi all,
We are facing the below situation, and would like to know your opinions on how to proceed.
We have a cluster environment ( server a and server b). A ESP Job is picking the files from a windows location and placing it in the unix location( server a or server b).
The problem is ESP job can place the file in only one server. This will affect the basic purpose of the cluster environment (then the file will always be processed from that particular server only).
If we place the file in both the servers, then there are chances that the same file can be processed mutilple times.
Is there a way that the load balancer can direct the file to either one of the server based on the load of the servers(just like how it does with the BPEL processes).
Or are there any other suggestions/solutions for this.
Thanks in Advance !!
Regards
Mohan

OPMN fails in cluster environment after the machie reboots.

Dear All:
Have you ever meet the following problem or have any suggestion for it? Thanks a lot.
There are machine A and B have been setup successfully in a cluster environment, everything is fine.
However, after the machine B reboots, the Oracle BI Server and Presentation Server in machine B could not start.
The error message for Oracle BI Server is:
[2011-06-02T10:40:34.000+00:00] [OracleBIServerComponent] [NOTIFICATION:1] [] [] [ecid: ] [tid: 1060] Server start up failed: [nQSError: 43079] Oracle BI Server could not start because locating or importing newly published repositories failed.
The error message for presentation server is:

The detail information is:
1)     Machine A and B both run Windows 2008 server 64bit.
2)     Machine A runs Admin Server+BI_Server1(managed server). Machine B is configured with “Scale out an existing installation” option and runs BI_Server2(managed server).
3)     BIEE 11.1.1.3
4)     In EM, the shared location of shared repository has been set to something like \\10.91.61.158\shared\RPD. The catalog path has been set to \\10.91.61.158\BIEEShare\CATALOG\SampleAppLite. Both path could be accessed by machine A and B.
5)     Before machine B reboots, everything is fine. All the servers could be started.
6)     After machine B reboots, the managed server BI_server2 could be started successfully. However, “opmnctl startall” would incur the above error message.
Any suggestion is welcome. Thanks a lot!

How to display XML generated dynamically, as TREE in cluster environment

hai guys,
we are generating a tree.xml file in server side as follows.
path = getServletConfig().getServletContext().getRealPath("/QBE/jsp/tree.xml");
BufferedWriter out1 = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(path),"UTF8"));
out1.write(xmlString + "</tree>");
out1.close();
"xmlString" holds the data in xml tag format.
in order to display the xml file in TREE structure, we are using a function like
function createTree()
var tree = new WebFXLoadTree("SMQ/AMQ List", "tree.xml");
document.write(tree);
ALL THIS MECHANISM IS WORKING FINE IN DEVELOPMENT ENVIRONMENT ANS AS WELL AS WHEN WE DEPLOY THE RELEASE IN LOCAL MACHINE. BUT IT IS NOT WORKING WHEN THE RELEASE IS DEPLOYED IN CLUSTER ENVIRONMENT.
Please help me out how to solve this...
thanks in advance,
Ranga
