Migrate Single Node 10g STreams to Multi Node RAC

We are currently running 10g STreams. One capture process enqueing LCR into one queue. Propagation job dequeues messages and propagates them to a Destination queue. Then our Apply process at Destination database dequeues and apply changes.
We have developed a single shell script STREAMSsetup.sh that does all the magic on setting up streams (capture, apply, propagator and the table queues.)
Now, we are in the process of designing our new Horizontal architecture with Oracle RAC. We envision it is going to be a Data Guard Migration from Single node to the RAC environment.
My question is, can we just let Data Guard takes care of that, expecting all Streams pieces will be in place within the RAC environment? OR do you recomment we remove all streams configuration and re-run our magic script STREAMSsetup.sh to set everything up again once migrated to the RAC environment. ???
I now Streams follows an Instance Owner rule when it comes to where Capture or Apply will be started or stoped.
I would appreciate if someone have had any experience with this type of migration provide any feedback.
Thanks,
Arqui

Yes, we are opening an SR. Everything is pointing into the direction of recreating Streams configuration from RAC/ASM environment once migrated, using the instance with the lowest Instance number in the Cluster. That instance will be registered as the Primary instance owner of the Buffer queue. If primary instance fails queue ownership is transferred automatically to the next instance in the cluster and capture is started automatically in the other node.

How to switch production single node EBS environment to multi node?

We're considering moving our production EBS environment from single node to multi node to separate out the middle processing from the database. We've completed the steps via clone (adcfgclone.pl) in out test environment and are now testing, however we're leery of running the same process in production. I've researched this process greatly, but most links point to either multi to single or cloning. Please assist.

Need Help in Data migration from standard 10g to standard to 11g RAC

Hi,
We are running an application in Standard 10g (Not RAC). Our service provider has installed a fresh standard 11g RAC and did not transfer the data from 10g to 11g RAC.
I want to migrate the 10g data to 11g RAC.
I wanted to know the followings
1) Easy data transfer technique (Data Pump or RMAN) & How do I do that (Steps)
2) How to backup the fresh 11g RAC (In case of errors in data transfer process to recover the base) (How to do)
Appreciate your help as I only have average knowledge in DBA.
Thanks.

Hi everyone.
I need clone system with 3 application server and 2 oracle database RAC and ASM to single-node. The operating system is RHEL 5.
I see some metalink notes, but we can't found nothing. I find notes with multi-node to single-node, but nothing with RAC to non-RAC.
The eBS version is 11.5.10.2 and database version is 10.2.0.3
Is possible this clone?
Thanks very much.

Oracle 10g multi node installation

Hi,
Multi node installation for Oracle 10g Appl Server
- Node A: Install core business Database server.
- Node B: Install Application Server Infrastructure (OID, repository database).
- Node C: Install Application server middle tier (forms, reports, portal, discoverer, java) at node C. must specify the OID server (node B). And configurre tnsnames to access database server (node A).
steps for this. Any doc or link
Thanking you
regards,

As simple as you mentioned.
1.- Install db in node A
2.- Install Infra in node B, you will get a servername and port for OID (look on $OH/install/portlist.ini to get it), and the password, usually the same as for the System and Sys users for the repository.
3.- Install Apps in node C, even if you install infra and apps in same node, the installer will always promp for the OID server name and port wich I mentioned earlier.
4.- Configure node C tnsnames to access node A
Hope this helps
Greetings.

R12 Single node to Multi-node Configuration

Hi All!
We have a single node setup (Applications and Database are on the same server). Now, our management decided to setup a Multi-node configuration and i'm the one who will do this.
The plan is to use Oracle ASM and RAC for the database and for the Application is to have a multiple application servers. For the database, we will be using a minimum of 3 servers and another 3 servers for the application. Is this possible? How can this be done. Can someone point or give some link or infos on how to do this. We're going to use the existing data on the single node server.
Thanks and Regards,

EBS 11.5.10.2 Merge Multi Node to Single node.

Hello,
I have a two node EBS Production application tier running on 11.5.10.2.
I have the concurrent manager running on Node A, and the rest of the services running on Node B. I'd like to retire the Node A server.
Can someone help me with the steps to move the concurrent manager to Node B and remove Node A from the configuration?
The steps I have come up with so far are:
1. Run maintain snapshot information on Node A & B.
2. Run perl adpreclone.pl appsTier merge on Node B.
3. Run perl adpreclone.pl appltop merge on Node A.
4. From Node A copy $COMMON_TOP/clone/appl to Node B.
5. Shutdown application tier on Node A & B.
6. Copy log and output files to Node B.
7. Run perl adcfgclone.pl appsTier on Node B.
8. On node B run :
Adadmin -> generate JAR files
-> generate message files
-> relink executables
-> copy files to destination
Adadmin -> Check for missing files, and manually copy files if needs
9. On node B run: EXEC FND_CONC_CLONE.SETUP_CLEAN;
10. Start Application tier and verify changes.
I'm not sure step 9 is right for this process. I want to keep the printer configuration.

1. Run maintain snapshot information on Node A & B.
2. Run perl adpreclone.pl appsTier merge on Node B.
3. Run perl adpreclone.pl appltop merge on Node A.
4. From Node A copy $COMMON_TOP/clone/appl to Node B.
5. Shutdown application tier on Node A & B.
6. Copy log and output files to Node B.
7. Run perl adcfgclone.pl appsTier on Node B.

-> copy files to destination
Adadmin -> Check for missing files, and manually copy files if needs
9. On node B run: EXEC FND_CONC_CLONE.SETUP_CLEAN;
10. Start Application tier and verify changes.
I'm not sure step 9 is right for this process. I want to keep the printer configuration.All your steps look OK to me -- -- (Sharing the Application Tier File System in Oracle Applications Release 11i [ID 233428.1] -- Section 4: Merging existing APPL_TOPs into a single APPL_TOP)
Step 9 is correct and you need to purge FND_NODES table and run AutoConfig on all tier nodes (you will not lose any printer configuration) --

Convert single node Multi Node

We have one requirement, our single node is running on sun server ( 11.5.10.2 with 9.2.0.7)
we want to convert the single node to 2 node, like this
Node 1 = DB + CM + ADMIN
Node 2 = FORMS, WEB
I want to follow the following procedure
(a) Copy the Total Application Tier File system from single node to Node 2
(b) Run the config clone on Node 1 and specify to run the services CM and ADMIN only on this node
(c) Run the config clone on Node 2 and specify to run Forms, web services only on this node 2
is the above procedure correct?

Has anyone installed XMLP in a multi-node appsTiers environment?

We are experiencing a problem with installing XMLP 4.5.
Our EBS 11i(11.5.9) configuration: dbTier is on HP-UX, admin/CM of appsTier is on HP-UX and web/forms of appsTier is on Windows, i.e two nodes appsTier.
Applying the major patch 3554613 (XMLP 4.5) created $APPL_TOP/xdo/11.5.0 on both UNIX and Windows nodes. But the $JAVA_TOP/oracle/apps/xdo is only created on UNIX node.
When we reported the problem of XMLP in relation to OA Framework (see my other posting on this forum) to Oracle, the support engineer said the patch should create %JAVA_TOP%\oracle\apps\xdo on Windows too. But he is not sure as he only has a single node environment.
We tried a couple of times of reapplying the patch without any luck.
We start wondering if the XMLP 4.5 can be successfully installed in a multi-node appsTiers environment.
So my question is:
Has anyone successfully installed XMLP in a multi-node appsTiers environment?
Thanks.

Hi
XMLP is installed on the apps middle tier so it should be no problem. The only thing, once you have it installed is if you want to use our cfg file you'll need to have the cfg file installed on all nodes.
Whats the TAR number ?

How to setup multi node installation

Hi all,
I have successfully installed Oracle E-Business Suite 11.5.10 in a single node.
But, I would like to get some suggestions on How to perform the multinode installation in which all the application tier servers in independent nodes?
If the nodes are placed in different places geographically, how can I move all these nodes in to a single network? Is this possible?
Please guide me.
Thanking in advance
Rameshkumar

1. Is it right if I assumed that we must check that
box if we want to install apps tier in more than one
server so that if we only want to install apps tier
in only one server then we don't need to check that
option? Or we better check it even no matter how many
server we installed apps tier into? You only need to check that box if you intend to used a shared application tier filesystem for a multi-node installation. If you are only going to have one app tier server, you don't need to check the box. If you plan on multiple apps tiers, each with its own copy of the application tier file system, you also don't need to check that box.
2. If I still uncheck that option will there be any
problem such as in backup & restore, clone, testing
activity, etc?No, should not be any problem at all.
3. When we created user for each db tier and apps
tier, what will be better, create the same user for
both tiers or differentiate user for each db tier and
apps tier? I'm thinking of using same user for both
tiers to avoid privilege problem later on.
I'd recommend the same user for application tier files on all nodes in the system, and a different user for database-tier files. For example, in our system the database software (RDBMS ORACLE_HOME) and database datafiles are owned by 'oracle', and the EBS application files (APPL_TOP, forms and web server, etc) are owned by a user called 'applprod' (though of course you should choose a user name that makes sense in your environment.
4. Can we start clone process in db tier and apps tier >paralel in multinode environment or still start clone >process in db tier first then apps tier?Still need to do the db tier first, since 'adcfgclone.pl appsTier' will want to talk to a database. :-)

John P.
