PCP in non-shared appl_top application tier

Hi Guru's,
I wanted to know few information about non-shared appl_top in application tier.
Can we implement PCP(Parallel Concurrent Processin) in non-shared appl_top application tier.?
What should be design of oracle application node in case of non-shared appl_top environment with HA(high availability)?
Regards,
Rajkumar Agarwal

Hi Hussien,
I am in process for load balancer configuration . I am still in doubt that it will resolve my problem that's why i am trying to explain my problem in detail .
I have configured shared appl top in active/active mode between 2 node. After configuration I tried to access apps login page from both the nodes separately like below
http://node1.domain:8000
http://node2.domain:8000
node1 and node 2 are my primary and secondary node.
If I access primary node url its working fine and there is not issue with that .When i tried to access secondary node, the login page url getting redirect to primary node only and login page appears.Which means application is accessible from primary node only and whenever I hit node2 its redirecting request to primary node which should not be the case in active/active configuration.
When I stopped services from primary node and tried to login from node2 ,I am getting "page cannot be displayed"
I ran autoconfig on node2 and its start working fine but primary node now converted into secondary node and redirecting login page to node2.
Now as a solution of above problem you asked me to configure load balancing , below are my questions
1. Is there any problem in configuration of shared appl top or its a default behavior of application?.
2. After configuration of load balancing , would i be able to access login page from both the nodes?
3. Incase my primary node goes down, will my application will be accessible from secondary node ?
Kindly clarify above queries in detail.
Thanks in advance,
Regards,
Raj

Sharing the Application Tier File System

I have two node with common storage(SAN) and i am planning to go for Shared APPL_TOP
ie. Form server, web server in Node A
Dbtier, concurrent, admin in Node B
How do i achieve high availably in this case
case 1) if the Node A fails what is the solutions
case 2) if the Node B fails what is the solutions
I thought i would go for shared Appl_top with load balance that means to keep forms and concurrent on both the servers, and Data guard (standby) for Database.
Is the solutions? any suggestion?
Any work around ?
Thanks in advance.

AFAIK, shared Appl_top is usfull when you have more than 2 nodes, for example 2 nodes of froms + web and 1 node CM+admin and the DB.
you can do it of cousre in your case and it will save you patching time for for high aviliblite you need at least 2 nodes of forms+web
maybe others can add on this

EBS 12.1.3 & clone from non-shared to shared appl tier: adcfgclone.pl error

Hi,
we have Oracle EBS 12.1.3 with 11gR2 in IBM AIX7.1. We are now cloning it from a non-shared appl tier to a shared appl tier. Shared appl tier is located in the network drive which uses NetApp.
I've been following these documents:
- Cloning Oracle Applications Release 12 with Rapid Clone (Doc ID 406982.1)
- Sharing The Application Tier File System in Oracle E-Business Suite Release 12 [ID 384248.1]
- Using Load-Balancers with Oracle E-Business Suite Release 12 (Doc ID 380489.1)
DB clone went without problems, but now I'm getting strange problems when trying to run adcfgclone.pl for apps tier:

This file exists:

I've tried to re-execute the cloning steps for app tier, but the problem persists.
I've cloned from non-shared to non-shared app tier without problems, so I have a feeling that this might be related to the shared network drive.
Any ideas how to solve this problem?

Hi Hussein,
thanks for the reply.
+The path is different (first path is db while the second one is apps), so copy the file from the source instance to $COMMON_TOP/clone/context/apps directory on the target instance and try then -- Troubleshooting RapidClone issues with Oracle Applications R12 [ID 603104.1]+
What I meant to say that CTXORIG.xml already exists in the correct directory in the target system:
$COMMON_TOP/clone/context/apps
Anyways, I recopied the file from source to the target system $COMMON_TOP/clone/context/apps, but still the same problem. I'll continue reading "Troubleshooting RapidClone issues with Oracle Applications R12 [ID 603104.1]".
I noticed below when running "perl adcfgclone.pl appsTier" with perl debug mode:

Sharing application tier- specifying configuration top

Dear all,
In note 233428.1 Sharing the Application Tier File System in Oracle Applications 11i
when running the script,
Absolute path of config top <Configuration_top> Location in which the iAS and 8.0.6 instance-specific configuration files should be stored. Specify a secure location for these files. For eg: Choose a local directory for storing the configuration files
which location I have to specify here ?
comments pls
Thanks
Yusuf

Hi,
We use $COMMON_TOP/conf for this location which is inherited as the value of the environment variable $IAS_CONFIG_HOME.
You may have your own choice of this location, though.

Move CM Node to Database node from Application Tier

Hi,
I have setup like this...my set up is 2 node...one node is Database node and another is Application Node.
Now I want to move Concurrent Manager Node from Application Node to Database Node..
I Can do this using RAPIDCLONE.....
What My Doubt is to move the CM Node...
Do I have to copy APPL_TOP , COMMON_TOP and ORA_TOPs or only APPL_TOP to database node
Plase help it out

Hi,
I want to Move CM to Database node using Shared Applicaiton File System Feature...It is very cool.....
I did not understand one point there...These lines are from this document
Sharing the Application Tier File System in Oracle Applications 11i Doc ID: Note:233428.1
Section 3: Sharing an existing Applications file system
In the 3rd point....
Make the Applications files accessible
Mount the shared disk to all application tier nodes
Suppose, I have Total Application Tier File System in the Application Node is in /u01 partition...Do I have to NFS Share this partition and Mount it in Database Node...is it correct??? like this I have to do it na....
(1) NFS share the /u01 partition File system in the Application Node
(3) mount the /u01 file system in the Database Node
$mount /u01 /u01
Is it correct ?????
If I have to apply any patch...Only we need to apply it on Primary node..once we apply it..it is automatically appearing the node 2....because it is shared file system....Only use is....For CM Running purposes..Database Node Resources(CPU and RAM) will be used......right.....
We no need to touch the Shared File System in the Database Node 2 in this scenario....right....
Please confirm it...

Query regarding converting application tier (concurrent and reports) into shared APPL_TOP

Hi,
Our E-business suite production server has four nodes configuration. 1. Application Nodes: APP1 , APP2 (Web and forms services are running on these two nodes) 2. Database Nodes: DB1, DB2 (DB-SRV - common name) (SAN storage with Active/Passive OS cluster configuration) Also the concurrent and reports services are running here.
Currently, the APP1 and APP2 application files are configured in shared APPL_TOP. It is not enabled for concurrent and reports services which is running along with database. I already checked the metalink doc id for the same.
I'm expecting your suggestion that we should take care while enabling the shared APPL_TOP for concurrent node+reports.
It would be also great, if any one give rough outline plan for the same.
Thanks in advance.
Regards,
Senthil

Hi,
Below is my plan to add the conc admin and reports server to the shared appl_top.
1. Run adpreclone.pl appsTier on the conc admin node. i.e. run adpreclone in node DB-SRV
2. Verify and enable context variable s_isAdConc, s_isAdConcDev context variables.
3. Mount the node-App1 application file system to node DB-SRV.
4. Copy the existing .rdf files(located in DB-SRV) to the shared appl_top.
5. Then run autoconfig on DB-SRV.
Can anyone review and let me know, if something is wrong here or need to be modified?
Regards, Senthil

Shared application tier

Hi,
I want to move to shared appl tier.
we have 1 node for database (srvdb1) 10.2.0.4 and
2 nodes for application (srvap1,srvap2) behind a load balancer and PCP configured.
I have created new QFS mount point which is visible on both application node.
I am reading Note 384248.1 but not clear.
i will be thankfull if any one kindly give step by step procedure.

Unified APPL_TOP in R12 for High Availability application tier?

Hi Gurus,
I have come up with an idea but i need your inputs on its possibility.
Consider: i have node1 and node2
Node1: Forms and Web
Node2: CM and DB
i have shared appl_top between node1 and node2.
My questions:
1. According to Unified APPL_TOP concept in R12, can i shift the FROMS AND WEB services from node1 to node2 incase the hardware on node1 fails?
2. Similarly vice versa, that is, can i switch CM from node2 to node1 incase node2 hardware server fails.
If yes, kindly inform me the resources and metalink note ids for the same.
Using above i am trying to make it HA application tier.
Please help on this.
Thanks.

Hi,
Sorry to update after long time. A just came to me.
384248.1 says that we need to use Linux OCFS for shared appl_top.The note does not say that you must use OCFS. :-) It says that OCFS2 is certified and supported for R12 application tier file systems. That does not mean that OCFS is your only option.
1> Is it compulsory to have OCFS to use shared appl_top? if yes what OCFS we should use?
No, it is not compulsory. If you want to use OCFS, however, the supported and certified version is specified in Note 384248.1 Another fairly common solution is to use NFS to deploy the shared application tier filesystem.

OraInventories in r12 shared application tier

Hi,
I have some doubts regarding oraInventories in r12.0.4 shared application tier
1)$ORACLE_home/inventory-->is local inventory located in evey oracle home RIGHT.
2)/r12/GOLD/inst/apps/GOLD_fbiprddb/admin/oraInventory-->it is global inventory which lists 10.1.2 and 10.1.3 homes only

Hi,
1)$ORACLE_home/inventory-->is local inventory located in evey oracle home RIGHT?Already answered this above.
2)/r12/GOLD/inst/apps/GOLD_fbiprddb/admin/oraInventory-->it is global inventory which lists 10.1.2 and 10.1.3 homes only and is located on primary application node only.so when i apply patches to these homes using opatch and oui i should apply on primary application node RIGHT?Correct (except for the global inventory which is explained in my previous reply).
3)there is another global inventory on database tier which is primary application node also path-->/r12/GOLD/db/tech_st/10.2.0/admin/oui/GOLD_fbiprddb/oraInventory which lists only RDBMS_ORACLE_HOME.So when apllying patch to RDBMS i should show this path of oraInventory RIGHT?I believe there is only one global oraInventory directory, which can be found in oraInst.loc file. For other directories, those are local inventories.

Shared Application Tier -- NFS Single Point of Failure

I am trying to convince mgmt that Shared Application Tier via NFS is the only way to go.
Currently, we have a 4 node environment, 1 dedicated to database, then 3 application tiers.
Is there any reasonable fault tolerant solution for NFS ??
I am not a storage expert, but can a storage area be created on a SAN, then have all tiers NFS to the SAN area ??
Inherently, the SAN devices are fault tolerant and dual HBA's to dual SAN switches provide protection.
Am I missing something ?? By the way, we are a Solaris shop.

Hi atul, I notice that this may be a dead thread but I belive the answer to your question is that when you run autoconfig and chek the log you will notice that there is a preliminary stage where it says updating contect values int he databse. at that point if the database has a higher serrial number than the filesystem file then the filesystem contect file will be updated by the values in the database *( i assume not all of the values. this will then result in createion of an updated xml file. in fact the xml file is rewritten every time you run autoconfig*

Shared Application Tier File System in Oracle Applications R12

Hi
Recently I came to an environment, here we are having 3 nodes with Shared Application Tier File System - One is Admin & DB and the other two are Applications Nodes(Apache and Forms) with load balancing. Its a Shared Application Tier File system so APPS_TOP is NFS mounted on two Applications Nodes. But i see ADMIN Node INST_TOP is also mounted on these two Applications Nodes...Could you please let me know what for this is????? or for what reasons we can keep like this?????

my question is Admin node and two Application Nodes are having INST_TOPS locally on those nodes it self,the best practice is to have $INST_TOP directory located on a each server local mount directory.
Re: Shared Application File System on Linux
other than that Why ADMIN Node INST_TOP is mounted on these two Application Nodes.you have to check with your admins who implemented initially.but best practice is to have $INST_TOP directory located on a server local mount point.

Shared and non-shared application file system in R12

Hi,
We have a oracle apps 11.5.10.2 on mutli node architecture with node 1 hosting DB,CCM and admin while node 2 hosting Form and web servers on Windows 2003.
Some of our Products are in Shared status(Installation) like AD,AU etc and I found that R12 currently does not support the shared file system infrastructure on application tier server nodes running on Windows platforms
Metalink note:384248.1
what will be the impact of this if we plan for R12 upgrade?
Thanks!
Shekhar

Hi Shekar,

I'm slightly confused by your question. Shared application tier file system isn't supported on Windows platforms in 11i, either. From Note 233428.1: 
<blockquote>
The shared file system infrastructure is not supported on application tier server nodes running Windows platforms or using Oracle9iAS releases earlier than 1.0.2.2.2. Application tier nodes must be running on the same operating system to implement a shared file system.
</blockquote>

Are you perhaps referring to the licensing status of your Applications products (i.e. either Installed, Shared, or Not Installed) from the Installed Products report in OAM? If yes, then this should have no impact on your upgrade to R12...those statuses should remain the same when you upgrade. "Shared" in this case relates only to the licensing status of the product, implying that the product is not explicitly licensed (i.e. Installed status), but its functionality is required for used with other Installed products.

Cloning with customization and shared application tier.

Hi,
I have to customize applications 11i and with creating a custom schema and customizing apache, please let me know what are the steps i should take so that the customizations are there when i clone the system in a shared application tier.
Thanks,
vp

Hi,
For cloning, you will have to follow the Rapid Clone document of your application release -- See (Note: 799735.1 - Rapid Clone Documentation Resources, Release 11i and 12).
For customization, please see (Note: 270519.1 - Customizing an AutoConfig Environment).

EBS 12.1.3 RAC to RAC Cloning with Shared Appl_Top

BismillahirRehmanirRahim
Dear All,
I need to Clone our Production EBS Environment from RAC to RAC with Shared APPL_TOP and Multi Tier Appl Tiers.
We have EBS 12.1.3 Environment with 2 Appl Tier Nodes with Shared Appl_Top & EBS DB is on 11gR2 RAC 11..2.0.4.
I am following Doc IDs 406982.1 & 559518.1.
But its not clear which directories need to be copy and restore for Shared Appl top on each Node.
Also what Steps will need to be executed on Each Nodes and
What Steps need to be executed only on one Node.
Appreciate your feedback.
P.S.
Kindly share if anyone have Step by Step Doc for RAC to RAC EBS Cloning.
