APEX without Oracle HTTP Server 10gR2

Guys,
I know that you can run APEX in Oracle XE without requiring to install an HTTP server.
But I have heard that the same is now true if you are using Oracle 10gR2.
Is this the case and if it is can you answer the following questions :
a) How is it done ?
b) How is it configured ?
c) Is this the way forward for APEX or do you still see the need for the HTTP Server ?
d) How would you migrate from an APEX application developed and deployed using an HTTP Server to one which does not ?
Any answers would be very helpful as I have a client who is extremely reluctant to install the Oracle HTTP server and I think that if you could use one which is within the database then that may win them over to APEX development.
Regards
Chris

Search the Oracle XE forum for dbms_xdb and dbms_epg, however, I don't know if it's possible to do what you want. You may need to run XE.

Error starting up ApEx's Oracle HTTP server

Hello.
I have just configured a brand new Oracle HTTP server on a brand new ApEx database. When I try to start the server, it doesn't start and I see errors in the log files.

orp244a is a 10.2.0.4 database into which ApEx has been installed per the install guide with no errors. The Oracle HTTP server is 10.2.0.1. Both run on Zemple. I have substituted the domain name and the password for APEX_PUBLIC_USER account with <my domain here> and <my password here>, respectively, for security reasons.
When I check http://zemple.<my domain here>:7777, I get the standard Oracle HTTP Server page. But when I check http://zemple.<my domain here>:7777/pls/apex I get the "Page cannot be found" error.

The main log in Apache/Apache/logs directory is not big, since it is a brand new install of the http server. Here is the complete log:

APEX and Oracle HTTP server

Scenario
We are considering using APEX with Oracle 10g. However, we don't have Oracle application server.At the same time we do not want to use the Oracle HTTP server(OHS) on the database server. The propsed application intend to use by approx. 5000 users
Questions
As APEX requires just OHS and mod_plsql plugin,
1. Can we install just Oracle HTTP server and mod_plsql on standalone server? Which CD need to be used?
2. Can OHS can be licensed separately as Oracle Internet application server(Enterprise Edition) based on processor licensing is expensive and not affordable.However, there are other options like Standard Edition and Standard Edition One as well but do not require any other options except OHS and mod_plsql plugin.Hence, what is the cost effective option to have OHS and mod_plsql as a middle tier component to deploy APEX applications
Thanks in advance

All,
I'm by no means a security expert, but I don't think this is a best practice. I think the best practice is to use two HTTP servers: one in the DMZ and one on the DB server. The one in the DMZ can be a standard Apache install - it acts as a proxy server and does not need mod_plsql. The second should be OHS. This configuration allows you to block ports that are usually used to communicate with the DB from the server in the DMZ.
Did I get that right or am I way off?

Dan

Can Oracle Portal work without Oracle HTTP Server ?.

Hi,
We are developing on Oracle Portal 10.1.4.
We are trying to use IPlanet Web Server instead of Oracle HTTP server. In such a case can Portal run with IPlanet Web server. alone ?.
Can we eliminate Oracle HTTP Server altogether ?.
Thanks and Regards,
Panai.

Third party HTTP Servers can be used with the OracleAS Proxy Plug-in. I have not done any tests with them however. The documentation states that it will enable you to integrate Sun ONE Web Server Enterprise Edition on UNIX and Windows systems, or the Microsoft Internet Information Server (IIS) on Windows systems.
Oracle Portal is tightly integrated with Oracle Web Cache. This might limit the usability of the OracleAS Proxy plugin.
More info is available in the documentation :

Down Time for Installing APEX 4.2.1 and oracle HTTP server?

Hi, all:
I plan to install APEX 4.2.1 and oracle HTTP server on 10.2.0.4 database.
Is there any down time required during installation?
I mean during installation, do I need to block users from accessing the database?
Can they do their normal data entry / inquiry?
thanks,
John
ps. There will be server backup before installation.

Hi,
Documentation says
>
3.1 Recommended Pre-installation Tasks
Before installing Oracle Application Express, Oracle recommends that you complete the following steps:
Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements".
Shut down with normal or immediate priority the Oracle Database instances where you plan to install Oracle Application Express. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node.
An alternative to shutting down the database is to prevent all users from accessing Oracle Application Express when upgrading your installation from a previous release of Oracle Application Express. Oracle only recommends this option in high availability production environments where planned outages are not available. For all other scenarios, the database should be shut down.
To disable access to Oracle Application Express when the existing installation is using the Application Express Listener, shut down the appropriate application server where the Application Express listener is deployed.
To disable user access to Oracle Application Express when the existing installation is using the Oracle HTTP Server with mod_plsql, you should either shut down the Web server or disable the Application Express Database Access Descriptor of the Web server.
For an existing installation using the embedded PL/SQL gateway, you should disable the Oracle XML DB Protocol Server by setting the HTTP port to 0. This can be accomplished by starting SQL*Plus, connecting as SYS to the database where Oracle Application Express is installed, and running:
EXEC DBMS_XDB.SETHTTPPORT(0);
Once you have prevented access from Oracle Application Express users, you should log into SQL*Plus as SYS, connecting to the database where Oracle Application Express is installed, and query V$SESSION to ensure there are no long running sessions which would interfere with the upgrade process.
Back up the Oracle Database installation.
Oracle recommends that you create a backup of the current Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included in the Oracle Database installation, to perform the backup.
See Also:
Oracle Database Backup and Recovery User's Guide
Start the Oracle Database instance that contains the target database.
After backing up the system, you must start the Oracle instance that contains the target Oracle database. Do not start other processes such as a Web Listener. However, if you are performing a remote installation, make sure the database listener for the remote database has started.

Do we need Oracle HTTP server to host Oracle Apex ?

We are completely new to this Oracle Apex.
Wanted to know the licensing part of it , before we get into it.
I guess Oracle Apex is free as it comes with the Oracle database license.
1) Do we need some kind of HTTP server to host the Apex on the browser ?
2) Does any HTTP server will work with Oracle Apex ?
3) Any other free Oracle tool which we can use instead of licensing Oracle HTTP server for this Apex ?
Correct me if I am wrong.
Thanks in advance for the gurus out here.

Correct me if I am wrong.OHS is covered by the DB license if OHS is run on the same server. See Joel's post and the document he links to: +{message:id=9256804}+.

Installing Oracle HTTP Server WITHOUT Universal Installer?

On my computer (Win XP, DB 10.1.0.4) the Universal Installer that comes with the Companion CD still fails at startup. So I installed HTML DB from the htmldb_2.0.zip file.
But what about the HTTP Server? How can install it without using the OUI?
The response file from the Companion CD offers only these two choices:
- Oracle HTML DB and Oracle HTTP Server
- Oracle HTML DB only
I have to admit that I don't really fancy the idea of installing HTML DB again via response file...
Any ideas?

Sabine,
Do you use an intel pentium 4?Yes. Do you think that bug is still around?No, I was confusing it because just recently I installed 8.1.7 on my XP machine and ran into that bug. It shouldn't affect a 10.x install.
What is the error message you get? Or does it just
crash?The windows error message "The oui.exe found a
problem and need to be closed." ("oui.exe hat ein
Problem festgestellt und muss beendet werden") Tough. Not much information.
Do you have anything special set up on your machine, firewall, cluster, etc.? How much RAM?
Sometimes the setup.exe didn't work for me. There is another oui.exe in the "install" subdirectory. Please try this one.
If you don't get any further I would suggest to open an iTar with Oracle Support.
If you had more specific error messages perhaps we can find something.
Please look in c:\programme\oracle\inventory\logs whether you can find more information.

Oracle HTTP server with multiples apex instances

It is possible to have an Oracle HTTP server installed in a diferente machine,
and apex Installed on databases there are in diferent machines?
Or it would be necessary to install one HTTP server for each APEX instance?
For instance:
Machine 3
___________DATABASE A
Machine 1 Machine 2 /
WEB BROWSER -----------> HTTP SERVER /
\ Machine 4
\___________DATABASE B

Yes, you can define multiple DADs - pointing to different machines/APEX instances - in one OHS instance.
See http://docs.oracle.com/cd/E21764_01/web.1111/e10144/under_mods.htm#i1055269 (for instance, just Google)

Oracle HTTP Server 9.0.2

Can I use Oracle HTTP Server 9.0.2 for HTMLDB 2.0? Is there any issue with that version?
Thanks.
Andy

What does the error_log of the Oracle Apache HTTP server say? This is typically in the $ORACLE_HOME/Apache/Apache/logs directory.
Weird that a mutex create failed. Without the actual o/s error code that resulted, it is difficult to diagnose the problem. Anything in the Application (or Security) Event Log? Access denied seems to indicate an ACL failure of sorts.
You could also disable FastCGI - it is not very often used and APEX (mod_plsql) does not need it. The httpd.conf file (in $ORACLE_HOME/Apache/Apache/conf) can be edited to disable FastCGI.

Hi all
That´s right, the OHS was installed with the Fusion Middleware Web Utilities installation and working fine !
The Apex application is online without problems.
Now, my challenge is to implement the security certificate (SSL) on OHS.
I´ve been read many things but I´m a little confused and looking for a specific documentation to do that.
The certificate was generated and got the especific files ( .cer / .crt / .key ) but the problem is how to configure.
Is it necessary to install another software ?
Is wallet manager must be used or just configure some files like ssl.conf ?
Thanks in advance for any help.

To install Oracle HTTP Server only

Hi,
I already installed Apex (3.0) in an Oracle database a while ago. I have used our Oracle iAS 10.1.2 as the application server. Now, I would like to install the Oracle HTTP Server in the database server and use it to run Apex. With the 10g companion CD, there is not any option to install the Oracle HTTP Server (Apache 1.3) only. Is there any way that I can install the Oracle HTTP Server only without installing Apex again? Where can I download it?
Also, I heard that there is a version of Oracle HTTP Server (Apache 2) bundled with Oracle 11g. Can I use it for Apex 3.0?
Thanks.
Andy

Hi,
See:
http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winsoft.html
Here you have the option, to install HTTP only
Kind regards,
Iloon
PS: be aware this cd contains apex 1.6 ;-)

How to configure Oracle HTTP server

Hi, I installed APEX 3.0 in Oracle 10.2.0.2 database. I installed HTTP server from Oracle 10.2.0 database companion CD. The problem is I am not sure which conf file I need to modify as in the installation document, it only shows steps for how to configure HTTP server 9.0.3/11g/Oracle Application Server 10g. Anybody knows where to get the right doc? Thanks.

Hi,
Configure the Oracle HTTP Server (OHS) from the companion CD is the same for other OHS (apart from OHS 9.x where it uses wdbsvr.app).
So just follow the install guide from
4.4 About Configuring Oracle HTTP Server
http://download-west.oracle.com/docs/cd/B32472_01/doc/install.300/b32468/post_inst.htm#BHAGICFJ

Can Oracle HTTP Server 2.0 be installed with Oracle App Server 10.1.3.4.0?

Or I guess a related question is what version of apache comes with the latest App Server Patch Set (10.1.3.4.0)?
We are running OAS 10.1.3.3.x and we are having issues with URLs that end in a number but which have query parameters at the end.
E.g. http://<stuff_here>/1?type=table&format=html
The URLs come from REST-ful GET operations. It seems like the HTTP server just ignores the query parameters completely.
When we run against stand-alone OC4J which includes an embedded HTTP server, such URLs work as expected.
We are hoping that perhaps the latest patch set for the full Oracle Application Server 10g will overcome this issue.
But if we need to move to a later Oracle HTTP Server (like the one that comes as an option for the Oracle 11g database installation) we would be willing to do so.
Comments related to this are welcome.
Thanks
Jim

Hi,
Does anyone have experiece getting Apex working with secured BI publisher?
The error I am getting when PDF printing from Apex to BI pub is:
"ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
Error failed
OK "
Please note, network services in 11G are already configured; thus I am able to print from Apex to non-secured BI pub.
Thanks,

Virtual Directory Change from Oracle HTTP Server to Embedded PL/SQL Gateway

We finally upgraded from htmldb 1.6 to ApEx 3.1.2 late last year. This was in conjunction with setting up a new server and installing Oracle 11g DB, while our production DB is still 10g. During this install, I opted for the Embedded PL/SQL Gateway, whereas our htmldb is running with the Oracle HTTP Server.
During the conversion of one of our applications I learned that Virtual Directory references to #IMAGE_PREFIX# are no longer valid for custom CSS so I had to change an entry in the page templates that I'm using to use #WORKSPACE_IMAGES#. Now I am importing another application from our htmldb 1.6 environment to our ApEx 3.1.2 environment, and I have a new problem that I think is related.
In this application we have been uploading report files for outside users to be able to download at their convenience. I think the upload is working OK, but when I try to download the report file I get the following:
Not found
The requested URL /apex/IMR.ofile was not found on this server.
The download is accomplished with a link on an SQL Report region. The Column Link info is:
Link Text = <img src="#IMAGE_PREFIX#edit_big.gif" border="0" alt="Icon 1">
Target = URL
URL = #OWNER#.ofile?p_file=#VIEW_REPORT#&v_auth=&APP_USER.
When I change the Link Text to <img src="#WORKSPACE_IMAGES#edit_big.gif" border="0" alt="Icon 1"> I lose the Edit Icon image. However, what I'm really concerned about is the URL not found error
Now, maybe I'm barking up the wrong tree, so if the problem isn't related to virtual directories, which tree should I be barking up?
Any suggestion?
Thanks,
Gregory

Is the IMR.ofile a custom package for downloading files? If so, you might need to add it to the wwv_flow_epg_include_mod_local function.
I am not certain how this function also plays into the embedded pl/sql gateway, but do know it would affect this running through Oracle HTTP server when configured with the before proc.
With the embedded gateway it may very well be that you need to add this package into the ACL for outside availability.

How to call webservice through Oracle HTTP Server

I have cluster of three Managed Servers. They are behind a Oracle HTTP Server. I deployed a web service to the cluster. When calling web service, I got the error. The error is that the client of web service can not directly access the Managed Servers.
The error tell that it can not access http://webapp01:7003/webservice/HelloWorld?WSDL
Where webapp01 is the host name of a managed server.
Is there a way that web service return the result to HTTP Server and HTTP Server return it to web service client.

1. Before you invoke the WebServices from client program, I guess you may have already generated the webservices client jar for the WSDL that is deployed using sun jdk "wsimport" command or bea's clientgen ant task. At this time, what is the wsdl url you gave. In the generated client jar file you should see .JAVA files also. Check the Service related .java file and check the WSDL URL in that file. If it is using weblogic servers managed server host and port, then the problem you see is obvious.
2. To fix this, you re-generate the webservices client jar file again this time giving the http server host and port instead of weblogic host and port. I am hoping you already modified httpd.conf file to accept the webservice url pattern. Check the .JAVA file generated for service to see the WSDL URL that is having inside.
3. Another approach is on your client side, before you invoke any operation on WebService, you will be first getting Service object, then Port object and invoke methods on Port object. When you get Service Object, you can pass the WSDL URL as one parameter and ServiceName (QName) as second parameter. Most of time we use default constructor without any parameters to get Service object. But you can use other constructor and pass 2 parameters. The WSDL URL will have HttpServers host and port, and rest of the url for wsdl will be the same.
In our env, we have similar requirment. SOAP BPEL Process WebServices are deployed on WLS 10.3.1 on a Cluster with 2 ManagedServers. We have Apache Proxy in front of this Cluster. All our WSDL requests goes to Apache host and port + wsdl url. This inturn goes to one of the managed servers at a time in round-robin. This is working. In httpd.conf we gave "MatchExpression / " so that any request from apache will go to cluster.
