Hi Atul,
Its really good post for multi-node installation.
During Fresh multi node R12 installation on Enterprise Linux.Below error is encountered on node2
AC-00002: Error: Unable to create log file
I am doing a . The install was successful on the Database Node and Primary Application Node. On Primary Application node only ‘Batch Processing Services’ are enabled.
However while installing on the additonal application node the rapidwiz is giving errors
‘AC-00002: Error: Unable to create log file – $INST_TOP/$CONTEXT_NAME/logs/12202114.log
Exception in thread “AWT-EventQueue-0” java.lang.RuntimeException: AC-00002: Unable to create log file –
$INST_TOP/$CONTEXT_NAME/logs/12202114.log
I had tried installing multiple times but every time it failed with the same message
The truss of the rapidwiz process showed this:
/40: open64(“$INST_TOP/$CONTEXT_NAME/logs/12202114.log”,
O_WRONLY|O_APPEND|O_CREAT, 0666) Err#13 EACCES
I think the reason for the failure:
On Node2 I am trying to write to an NFS mount. If I access an NFS mount from a server other than its origin, the root user of the application server is treated as nobody user. I verified this by touching a file while logged in as root:
-rw-r–r– 1 nobody nobody 0 Dec 20 10:59 abc
I have mounted successfully from node2 using
mount -t nfs nas1:/erparch /erparch
What necessary steps are to be taken in order to proceed with installation on second node.
ReplyHi,
By giving no_root_squash option in node1 /etc/exports file with nfs mountpoint, Rapidwiz ran successfully on node2.

Hi Atul,
its a nice document,
i’m doing a fresh R12.1.1 installation using 11g RAC Database.
2 node 11gR1 RAC
2 node CM
4 Node HTTP/Forms.
i’m unable to find any option for RAC in rapidwiz, please help/point me to correct procedure.
thanks and regards

@ Habib
It is not possible to install RAC with R12 during installation. Only option available is to install R12 with single node database and then migrate database to RAC using Oracle My Support Note 823587.1 Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 12
that was super fast,
really appreciate it.
thanks and regards

Hi Atul,
I appreciate your efforts in making this site such a good source for training and learning oracle Apps.
I have started learning Apps following for your training guidance?
In a multi node installation , how do the database tier and application tier communicate with each other. Is it just enough if they are in a network?
If Iam installing on my laptop on vmware with two guest Linux OS, how can I do a multi node install?
Thanks
Prashanth
@ Prashanth,
Q: In a multi node installation , how do the database tier and application tier communicate with each other.
A: Using jdbc and mod_plsql (11i)
Q: Is it just enough if they are in a network?
Yes, tnsnames and jdbc connection will automatically be configured during installation.
Q: If Iam installing on my laptop on vmware with two guest Linux OS, how can I do a multi node install?
Create two Linux machines, ensure they can ping to each other and resolve hosts and then start installation on first machine and when prompted for database node give machine as hostname1 and on application tier screen give hostname2
once installation is over on hostname1 then copy conf_$SID.txt from hostname1 or hostname2 and then start installation from hostname2 and use conf_$SID.txt as mentioned in above post
ReplyHi Atul,
Thanks for the prompt response. I have started download of R12,a lot of files to download.Iam hoping it would complete in couple of days :-).

ReplyIs there any guide for “advanced installation methods” for example “2 db node and 1 apps”(For failovers of database),
This is implemented by converting apps database from single node database to RAC database . Docs are available in Metalink (Oracle My Support) site – search for “Oracle Apps RAC”
“2 apps and 1 db”(For load balancing) e.t.c ???
Same for this search for “advancved deployments apps r12”
[…] Other Apps DBA -articles 26 09 2010 Oracle Apps R12 distributed / Multi Node installation […]
ReplyHi Atul,
Thanks for your wonderful articles. I am learning apps. Can you please clarify the following:
I have done multi node R12 installation on solaris.
Node 1: DB + CM + Reports
Node 2: Forms + Web + , all other
now thru application, I see conc managers are running on NODE 2 !!
I even verified at OS level,
bash-3.00$ ps -ef | grep FNDLIBR
My installation was correct. I documented screen shots of this installation, it is same as I wrote above.
Please can you advise on this.
Thanks
Reply@ Mubeen,
Check entry in FND_NODES in apps schema
Also check context file (xml file on both nodes – $CONTEXT_FILE ) and look for isAdConc on both nodes
ReplyAtul, thanks for your prompt reply. please see the following output:
Apps node (NODE 2)
YES
YES
DB node (NODE 1)
YES
YES
SQL> select node_name,SUPPORT_CP,STATUS from fnd_nodes;
NODE_NAME S S
—————————— – –
ORA10GSERVER Y Y
MODTEST1 Y Y
AUTHENTICATION N
Is it possible that in multinode, whatever we choose all services are deployed on all nodes ? then later disable services !
thanks again
Replyjust gone thru 415385.1. it says,
in R12, concept of unified APPL_TOP is introduced which means everything is laid down on all servers.

Reply@ mubeen, Yes in R12 all files are installed (unified appl_top) but services are configured to start on nodes based on context file configuration (or services configured during install time).
Change your XML file on Node 2 with variable related to concurrent manager (*Con*) from Yes to No, run autoconfig and then restart services .
ReplyHi Atul,
I have the following requirement for installing R12.1.1 release for EBS:
DB: AIX 6.1 64 Bit LPAR
APPS and Middle Tier: OEL 5.7 64-Bit
I have procured and staged the EBS software for both the OS in their respective staging area.
Now following your multinode/distributed install example as above can I specify the MAchine1 to be AIX and Machine 2 be the Linux.
I am pretty much sure that I will have to run the installer twice for the Db on AIX and for the APPS side on Liunx. However, I wonder how the installer will behave when It installs the DB on AIX? I am not sure on how to achieve this other than following the MOS article: Application Tier Platform Migration with Oracle E-Business Suite Release 12 [ID 438086.1] (https://support.oracle.com/CSP/main/article?cmd=show&id=438086.1&type=NOT)
Is it possible for you to shed some light here, it will be much appreciated?
Regards,
Vasu
@dimaggio,
Install EBS database on AIX using ebs installer for AIX and EBS middle tier on Linux using ebs installer from Linux .
During installer screen on AIX , you specify middle tier server details
ReplyHi Atul,
If I want to do a multinode install with a loadbalancer as a web entry point, and two Concurrent Management tiers, and four Application tiers (Forms, Web, etc) does Rapid Installer give me an option to do that?
thanks
Vivek
Another question on the same topic, if I have SSL termination at the Load Balancer, and non-SSL traffic after the load balancer to the the Application tiers, do I have to do any SSL config steps in EBS at all?
Thanks
Vivek
@ Vivek Sharma,
Yes , there are around five parameters in context file that you need to change . Check this http://onlineappsdba.com/index.php/2007/10/04/oracle-apps-11i-r12-and-ssl/
Hi,
Is PCP and RAC architecture supported on windows server for R12 installation.
Hi Atul,
I need to install Oracle Applications R12.1.1 form, web, conc node on Linux (64bit)and Database node AIX bit(64).
Please suggests.
Reply@ Ranjan,
You need R12 software for both AIX and Linux.
Run installer on AIX and select Database node as AIX host and Application Tier in Linux Machine.
Follow R12 installation guide that has two node (split configuration) installation .
ReplyHi Atul Kumar
I am the administrator of a server used Oracle SOA Oracle 10gR2 Forms and Reports.
Resientemente we are in the process of migration to weblogic 11g.
on the server we have an application that is deployed as a new OC4J instance

ReplyHi Atul,
I m trying to install apps r12 on multi node at the time of giving “Load the following saved configuration” then it will showing the “unable to retreive config file from database please verify database connect string . so can u please help me
Hi Atul,
Nice article.
I tried and worked well in single node with multi-user like oracle and applmgr and multi-node with oracle user(oracle in db tier node and oracle in app tier node).
but when I am trying to install EBS 12.2.4 in Oracle Linux 6 with multi-node(2 nodes) and multi-user(oracle in db tier node and applmgr in app tier node), I have an error like this.
Do you have idea for that error?

ReplyAfter referring your link,
the 5th point says that : For multi-node (distributed) installation you get an option to use shared application tier file systems (multiple machine sharing same application tier file system) .
BUT Shared application tier option is not available for windows.
So what to do in that case as i have to do installation for windows??
Reply@ Mitali, Are you doing multi node installation ? Do you have a requirement to use shared application tier ? Post these questions in our private facebook group as you need more help . We cover all these things in our Apps DBA training http://www.k21technologies.com/oracle-apps-dba-training

Reply@Mitali,
Please click X to see what all check in system utility failed. Do you have installation guide and did you complete all the pre-requisite checks to install EBS 12.2 on windows ?
You can post this question on our private facebook group too with screenshot of error https://www.facebook.com/groups/k21technologies/
ReplyHello everyone,
I have installed E-business suite on my system. Need to work on iRecruitment tool. But on the home page i could not find it. I made a new user having HRMS responsibility. So please help me to get started with iRecruitment. There is no such predefined responsibility as iRecruitment. What to do??
Hi Atul,
My requirement is to setp EBS 12.2 in high availability in multi-node installation(2 db and 3 app tier), Could you please share the installation steps to configure in HA.
thanks,
Karan
