AppsLocallogin shows blank page or HTTP-403

An instance which had a new virtual name was recently cloned. Whenever the E-Business Home Page link (which points to was clicked it showed up a blank page or HTTP-403 (If you go to Internet Explorer -> Tools Menu -> Advanced -> uncheck Show friendly HTTP error messages).

mod_jserv.log showed a lot of errors like this one:
..] [error] OPM:Can not find one alive process
These errors indicate that Jserv is not up-and-running. This is confirmed by the following entry in the error_log which indicates that oprocmgr is not able to find a active Jserv JVM.

If you check the Apache access log :

grep 403 $IAS_ORACLE_HOME/Apache/Apache/access_log

It would return a lot of lines similar to this one: - - [12/Sep/2007:17:25:55 -0400] "GET /oprocmgr-service?cmd=Register&index=0&modName=JServ&grpName=DiscoGroup&port=17140 HTTP/1.1" 403 226

This means that oprocmgr-service doesn't trust

I checked the "s_oacore_trusted_oproc_nodes" variable in xml file and it pointed to the new virtual name only. I added the also


and ran autoconfig. The problem was solved. If you do not want to run autoconfig, the file to modify is $IAS_ORACLE_HOME/Apache/Apache/conf/oprocmgr.conf

Port 1234

Order Deny,Allow
Deny from all
Allow from localhost
Allow from justanexample
Allow from
Allow from -- Added this line

This problem and its solution is well documented in metalink note 372096.1.

You should add this line in these files present in $IAS_ORACLE_HOME/Apache/Apache/conf/


Allow from

Thanks for the encouragement Arun. Little drops of water make an ocean. My rule of at least one post a day, keeps the blog alive. I manage to find at least one new thing/issue about Oracle Apps which is not already present in the blog.

I am a little new at this. I have an app servers "ows1" and at DR site "ows3". I want to achieve the switchover through the DNS naming. I created a new name "ows0" which now points to "ows1". Everything works fine with "ows1". The URL ""
works well. Created a new context file and run the "" for the "ows0". When I try the URL
it gives the 403 error.

I added both the virtual and physical servers to the oprocmgr.conf, and it still gives the 403 error.

Any ideas?

When Apache/Jserv starts it checks the hostname from which traffic is coming. If that hostname is not allowed in oprocmgr.conf and httpd.conf, then you get http-403. So, when your ows0 Apache is not allowing traffic from ows1. The oprocmgr.conf and httpd_pls.conf both need to allow ows1. Try it and let me know if it worked.
