Issues with using Embedded PL SQL Gateway with Apex 4.2

Hi,
I have installed Oracle 11g R2 and want to develop an application using Apex 4.2 (needs upgrade from 3.2 version which has come bundled).
For the server, I would like to use the Oracle HTTP server, but it seems to require a separate license as against the same in Oracle10g.
I would like to know what are the performance related issues b/w using the embedded PL/SQL Gateway (Oracle XML DB HTTP Server) that comes with Oracle 11g R2 as against the HTTP Server found as a part of the fusion middleware bundle. Is it wise to procure the license for HTTP Server?
Details:
DB OS: Windows 7 (64 bit) (DB and Apex are on the same machine)
Number Of Users of application: 10-20
Application is mainly used more for keeping track of details as against heavy processing or the like
Thanks

For the server, I would like to use the Oracle HTTP server, but it seems to require a separate license as against the same in Oracle10g.What gives you this impression? The licensing position remains the same: 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}+.

Where is HTTP access and error log when using Embedded PL/SQL Gateway?

Hello,
I am using Embedded PL/SQL Gateway to run stored procedures.
I can't find access log and error log (something like Oracle HTTP Server has).
In listener.log are only simple data and there are no usernames and procedure names...
Thanks.

Setup for PDF printing using Embedded PL/SQL Gateway, 11G DB and APEX 3.1

I've setup APEX on 11G using the Embedded PL/SQL Gateway. Its all working well.
I've enabled Network Services and can see a couple of printers I've defined after running
select * from DBA_NETWORK_ACLS;
and also can see the FLOWS_030100 and FLOWS_030000 users when I run
select * from DBA_NETWORK_ACL_PRIVILEGES;
I have been through http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html and can see that I have a few choices ...
* Oracle BI Publisher,
* Apache FOP or
* some other XSL-FO Processing Engine.
I am not able to use Oracle BI Publisher ... license required:-( ... so that leaves the other two choices .. as I'm using the Embedded PL/SQL Gateway the Apache FOP is not an option ..
that leaves other XSL-FO Processing Engine .. has anyone had any experience in this area .. and can give me a few pointers ...
I'm kinda surprised I have little choice .. am I missing something?

Adam

Adam,
>> as I'm using the Embedded PL/SQL Gateway the Apache FOP is not an option
Not a true statement. Using Oracle Containers for J2EE (10.1.3.2), as listed in that document you reference, is all you need to use Apache FOP. You don't know the full-blown Apache.

Using a Domain name with embedded PL/SQL Gateway

Hello all
I wish to link domain name to an application
e.g. www.mydomain.com goes to application 100
or www.ano.mydomain.com goes to application 135
I have successfully done this in the past using HTTP server.
My new installation does not used HTTP server ... I have only configuration Embedded PL/SQL gateway
Can I route using embedded PL/SQL gateway a URL to an application?
Thanks

Please check with new version of TFTPD 32 server. The error may be due to older version of TFPT server, the new version available solved this error. Files are getting uploaded with no issues.
1. Download tftpd32b.zip from:
http://tftpd32.jounin.net/tftpd32_download.html
2. Copy the tftpd32b.zip file into an empty directory and extract it.
3. Copy the file you want to transver into the directory containing tftpd32.exe.
4. Run tftpd32.exe from that directory. The "Base Directory" field should show the path to the directory containing the file you want to transfer.
At this point, the tftpserver is ready to begin serving files. As devices request files, the main tftpd32 window will log the requests.

How to redirect on Embedded PL/SQL Gateway installation

Hi,
I'm working with APEX on a server where the installation was made via Embedded PL/SQL Gateway (all previous installations on other servers where made via Mod Pl/SQL, so I'm not familiar with this one).
I have 2 applications now, both of them have already DNS Alias created so users can access with a Friendly url. But both of this alias goes to the same application, cause I don't know where to define this (I believe on Mod Pl/SQL installation this was easy to configure on the httpd.conf file under Apache directory).
Does anyone know how can I do this ?
Also the other issue I'm facing is that I can access with any of these alias, but it automatically changes the url to the IP and Port of the server. Is this also configurable via Embedded PL/SQL Gateway?
Thanks in advance.
Regards,
Ivo

This sounds very similar to my situation which I have already posted a thread about, which might have started on upgrade to Windoze 7.
I've tried changing ports, reinstalling apex and fiddling with all sorts of things.
Strange thing is - it works if I unplug the internet cable.
I can't find any logs which provide anything useful.

How can I enable embedded pl/sql gateway to run on port 80

I have a new 11G install on OEL 4.0, database created. I would like to be
able to access the instance using the pl/sql gateway. Works fine with
port 8080, the default. How to I enable it to run on port 80?
I found this statement in the following docuementation:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb22pro.htm#ADXDB2500
Using HTTP(S) on Nonstandard Ports
By default, HTTP listens on a nonstandard, unprotected port: 8080. To use HTTP(S) on
the standard port, such as 80, your DBA must chown the TNS listener to setuid ROOT
rather than setuid ORACLE, and configure the port number in the Oracle XML DB
configuration file /xdbconfig.xml.I have root priviledges on the box.
I've tried setting the listener file permissions:
chown root:dba /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
chmod 6775 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
Also put root in the dba group.
The permissions turn out like this:
-rwsr-sr-x 1 root dba 830854 Jun 17 21:04 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
I stopped the listener, bounced the database, and started the listener again.
But it still shows the process being owned by oracle:
oracle 29682 1 0 21:08 ? 00:00:00 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr LISTENER -inherit
Changing the port is easy:
Connected to:
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SYS>select dbms_xdb.gethttpport as "HTTP-Port" , dbms_xdb.getftpport as "FTP-Port" from dual;
HTTP-Port FTP-Port
8080 2100
At this point, I can access the apex home page with the following url:
http://hostname:8080/apex/f?p=4550:10:1454849288245548
I can than change it to port 80:
SYS>begin
dbms_xdb.sethttpport('80');
dbms_xdb.setftpport('2100');
end;
2 3 4 5
PL/SQL procedure successfully completed.
SYS>SYS>select dbms_xdb.gethttpport as "HTTP-Port" , dbms_xdb.getftpport as "FTP-Port" from dual;

When I try to access apex with the following url:
http://rmdcopslnx1.us.oracle.com/apex/f?p=4550:10:1454849288245548
I get the following:

* Could the site be temporarily unavailable? Try again later.
* Are you unable to browse other sites? Check the computer's network connection.
* Is your computer or network protected by a firewall or proxy? Incorrect settings
* can interfere with Web browsing.I can set the port. Just can't talk to it.
This is the entry from the listener log:
<msg time='2008-07-03T15:40:09.741-06:00' org_id='oracle' comp_id='tnslsnr'

</msg>
So this looks like an permissions problem. But where? I posted
this on the apex forum here:
Re: How can I enable embedded pl/sql gateway to run on port 80
They suggested asking here.

No, that thread did not provide the information that I need. Some more data:

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.

Enable SSL/https on ApEx Embedded PL/SQL Gateway/11g?

Hi,
I'm a newbie to ApEx. And I notice that most of ApEx applications are run on "http" instead of "https". Aren't you concerned about its security? What's your take on SSL/https with ApEx?
I understand that it takes several steps to set it up on Oracle HTTP Apache server (ie: set up Oracle Wallet Manager, go to a certificate authority to get obtain a certificate, configure Oracle HTTP Server...etc). But does it work on Embedded PL/SQL Gateway (ie: runs XML DB HTTP instead of a separet Apache web server)?
Any experience/suggestions/ideas?
Thanks much,
Helen

Can you run Embedded PL/SQL Gateway and Oracle HTTP Server at the same time

Hi,
I know this will sound a bit odd but their is a business case for asking this. Can you run APEX via the Embedded PL/SQL Gateway and the Oracle HTTP Server at the same time? Would their be any security/stability/etc issues I'd need to worry about? I know that I'll need to run them on different ports.
Thank you,
Martin Giffy D'Souza

I think I've done this in the past. Theres no technical reason why you can't do this as far as I know.
I can't remember if I used different ports or same port.

Can I change from Embedded PL/SQL Gateway to Oracle HTTP Server/Apache?

Hi everyone
Can I change a running installation of Oracle 10.2.0 Application Express 3.2.1.00.10 to move away from the Embedded PL/SQL Gateway on to the Oracle HTTP Apache server? I'd like the change to be as transparent as possible to avoid an outage if I can. Do I need to reinstall everything and just import a backup or is there a way to switch between the http servers? I couldn't find anything on "switching" in the User's guide, so I was hoping one of you may have successfully tried this.
Many thanks for your help!
m.

It should be straight forward with a very small downtime. Test on dev system before interrupting the prod system.
1. Install OHS
2. Configure OHS
3. Configure the mod_plsql plugin
4. Stop the Embedded PL/SQL Gateway
Let the users know about the new URL.
All the above steps are documented in the docs.

Where is "httpd.conf" file in Apex 3.2 w/ embedded PL/SQL gateway (in 11g)?

Hi,
I need to config the file to direct the standard ApEx URL (ie: http://xxx.x.x.x:8080/apex/f?p=108:1) to a nicer URL (ie: http://xxx.x.x.x:8080/apex/test.html, for example) to the end users. I believe the file should be located in something like $ORCLE_HOME/Apache/Apache/conf in the Oracle HTTP Server Apache web server version. However, it's NOT in the Embedded PL/SQL Gateway version.
Any idea?
Thanks much,
Helen

I don't think that you could do this using the native embedded gateway. Since it is not actually running Apache. It is actually running through the XML DB connectors.
2 options:
1) Use a front end server as a proxy, or as the mod_plsql gateway
2) Pretty up your URL's using the application/page aliases: http://xxx.x.x.x:8080/apex/f?p=app:page where app and page have been assigned as application and page aliases resp.

Is Embedded PL/SQL gateway installed

Hi,
I am trying to find out if my oracle "10gR2 standard edition" meets the requirements to install Apex 3.2.1.
Is there a view to query if "Embedded pl/Sql gateway" is installed or "Oracle http server and mod_plsql" is installed.
Can we query such requirements from dba_registry view?
thanks in advance,

Hi,
dba_registry will give info on Oracle components for which catalog ha been created in the database. But there could be some components installed on the binary but not used in the database. To check what components has been installed, you can use Oracle installer and then choose installed components from the first o 2nd screen.
