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.

If i have any customize configuration will this configuration comes automatically when i clone.
if not then how to find existance of customize configuration in my previous instance, and how to migrate it.What customization you are referring to? Are you referring to "Section 7: Migrate Non-Shared Application Tier to Shared Application Tier File System"?

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.

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).

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.

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.

Shared Application File System.

After moving to shared application tier in production
In $IAS_ORACLE_HOME/Apache/Apache/conf I see the security.conf file has version security_ux_ias1022.conf 115.25 2009/04/23 10:04:40 mmanku ship $
but in $CONFIG_TOP/Apache/Apache/conf the sercurity.conf file has the following version security_ux_ias1022.conf 115.29 2009/12/21 05:56:02 sbandla ship $
Which top does oracle use ?
why is the shared IAS Home have a lower version of than the CONFIG_TOP
why does not the one which is not used gets deleted?

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.

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

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:
"applmgr@myhost:/d01/shared_mount/apps/apps_st/viscomn/clone/bin # perl adcfgclone.pl appsTier

This file exists:
/d01/shared_mount/apps/apps_st/viscomn/clone/context/apps/CTXORIG.xml
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?
BR,
TH

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:

Internal and External application tier File move

Hi all,
I am new oracle apps R12 with 3 tier instance.
We are created the oracle apps R12 instance with 3 tier. Two tier is Application tier and one tier is Database tier.
The data base tier is common for both application tier. The issue is, we are moved the all customized Development works into only one application tier (i.e. Internal tier). So we are not moved the all customized Development work into second application tier (i.e. External tier).
My question is, we are not moving all customized work into both application tier means , is there any issue will occur ?
How can we handle my customized works both application tiers( i.e. Internal and external tiers) ?
Please help,
Thanks,
Prab.

Hi;
They are questioning me why we have to do that.Answer is easy, You can mention for ebs stability all nodes should be on same level :) If they push you more please show metalink notes which is already sharing by Hussein Sawwan. If they still persist say them you will go wiht SR and confirm wiht support ;)
PS:Please dont forget to change thread status to answered if it possible when u belive your thread has been answered, it pretend to lose time of other forums user while they are searching open question which is not answered,thanks for understanding
