Http_server is shown as Down.


I then used adapcctl.sh status to check on these services and sure enough the http server would not start:
[applmgr@oracleupk scripts]$ ./adapcctl.sh status

Checking status of OPMN managed Oracle HTTP Server (OHS) instance ...
Unable to connect to opmn.
Opmn may not be up.

adapcctl.sh: exiting with status 0

adapcctl.sh: check the logfile /u01/appl_top/inst/apps/PROD_oracleupk/logs/appl/admin/log/adapcctl.txt for more information ...
  

Cause:-

The root cause for all the failures was that Apache (http) didn't start up because of not having latest RPMS as per install documents
I downloaded and apply the patch 6078836 from OracleMetaLink to fix an issue with the Oracle HTTP Server bundled with the E-Business Suite technology stack .

[applmgr@oracleupk scripts]$ unzip p6078836_101330_LINUX.zip
Archive: p6078836_101330_LINUX.zip
creating: 6078836/
inflating: 6078836/libdb.so.2
inflating: 6078836/README.txt

[applmgr@oracleupk scripts]$ cd 6078836/[applmgr@oracleupk scripts]$ ls
libdb.so.2 README.txt

Then we copy to /usr/lib. 

After the install, when trying to start up the http server, this happens:
$./adapcctl.sh start 
You are running adapcctl.sh version 120.7.12010000.2

Starting OPMN managed Oracle HTTP Server (OHS) instance ...
opmnctl: opmn started.
opmnctl: starting opmn managed processes...

adapcctl.sh: exiting with status 0

adapcctl.sh: check the logfile /u01/appl_top/inst/apps/PROD_oracleupk/logs/appl/admin/log/adapcctl.txt for more information ...



If you see the post installation steps, we can see now the previous errors have been fixed.

 

  


















But, still we have the a Login page error.
The quick workaround to fix this error was:

• Stop the Apache Server
• Open the /etc/hosts file and check the configuration setttings correctly
• Start the Apache Server
• Click to Retry option for performing post installation checks again
