Oracle Apps (EBS) R12.2 Installation: WLS Domain Validation failed

Oracle Apps (E-Business Suite) current release (as of Sep 2015) is Oracle E-Business suite is 12.2.4 also commonly known as R12.2 . WebLogic Server is introduced in Oracle E-Business Suite as part of 12.2 version . In this post we are going to cover Oracle Apps 12.2 installation issue encountered by one of our Oracle Apps DBA trainee while installing EBS 12.2 on Linux Server as part of Hands-On (next batch starts on 31st October, 2015 and We cover Architecture, Installation, File System, WebLogic Concepts, Patching, Cloning , Common Tasks and difference in 12.2 from previous version. Register here for Oracle Apps DBA 12.2 Training )

In this particular case, one of the post installation check “WLS Domain Validation” failed as shown below .



Click on Red mark button ( ! ) to check why WLS Validation failed. In our case, it was showing:

EBS Domain validation failed for RUN filesystem.
Check Domain deployment logs and re-deploy the RUN domain.

After checking the log file (located at /<base_directory>/fs2/EBSapps/appl/admin/<instance_hostname>/log/ deploytech.log), we came to know that there is some issue with OHS instance as shown in below error messages.

Successfully updated context variable s_ohs_installed with the value generateEBSOHSConfigFiles
opmnctl startall: starting opmn and all managed processes…

EBS_web_PRD84 is failed to start !!

.end std out.
opmn id=<hostname>:6285
Response: 0 of 1 processes started.

ias-instance id=EBS_web_PRD84_OHS1

–> Process (index=1,uid=1443244297,pid=10563)
failed to start a managed process after the maximum retry limit
/u01/oracle/ PRD84/ fs2/FMW_Home/ webtier/instances/ EBS_web_PRD84_OHS1/ diagnostics/ logs/OHS/EBS_web_PRD84/ console~OHS~1.log

.end err out.

ERROR: Unable to create OHS instance.
Failed to create the OHS instance

So we checked in the given OHS log file (/<base_directory>/fs2/FMW_Home/webtier/instances/<instance>  /diagnostics /logs/OHS/<instance>/console~OHS~1.log) and got the exact error behind the issue that was “Address already in use“.

[2015-08-20T14:28:40.4043+01:00] [OHS] [INCIDENT_ERROR:32] [OHS-9999] [worker.c] [host_id: <Hostname>] [host_addr: <IP of Host>] [pid: 10527] [tid: 47435944011936] [user: <application_user>] [VirtualHost: main] (98)Address already in use: make_sock: could not bind to address [::]:8084

Root Cause:

As shown in the above log, 8084 port (OHS Port) is already being used by other application that’s why unable to bind to that address.



To check which process is using port 8084  (PID 2823 in our case)
[root@host ~]# lsof | grep 8084 | grep LISTEN

httpd  2823  oracle84  18u  IPv4  6925093  TCP *:8084 (LISTEN)

 [root@host ~]# ps -ef | grep 2823
 oracle84  2823  2745  0  Aug17 ?  00:00:00                   /u01/oracle/PROD84/ apps/tech_st/10.1.3/Apache/Apache/bin/httpd -d /u01/oracle/PROD84/apps/tech_st/10.1.3/Apache/Apache -DSSL -f /u01/oracle/ PROD84/inst/apps/ PROD84_iamdemo07/ ora/10.1.3/ Apache/ Apache/conf/ httpd.conf

To kill the process, run command:

[root@host ~]# kill -9 2823 <PID>

The solution provided above resolved the issue (after this start services manually and click on Retry)

    Hi Amol,

    Thanks for writing to us!

    Both are two different career paths.If you are very strong in database then learning RAC you can become a core apps DBA Also rac is complimentary for Apps as well, knowing both is good for market.My suggestion learn apps first, as you already spent 2 years in apps DBA field.RAC you can learn later.Also, you needs to know core apps skills before learning on cloud world.

    You can do cloud later after you gets a good handle on apps.

    Thanks and Regards,
