Dynamic SQL and PL/SQL Gateway

This question is kind of out of curiosity...I had created a procedure that used some dynamic sql (execute immediate), and was trying to use it on pl/sql gateway. I kept getting page not found errors until I removed the execute immediate statement, and reverted to using static sql statements.
I am just curious, is dynamic sql not supported at all with pl/sql gateway?
Thanks
Kevin

Well, you're one of the few that actually read the docs.. And one of many that lacked to state any real technical details for forum members to understand the actual problem, the actual error, and what the environment is that this is happening in.
Remember that you came to this forum for forum members to help you. In order for us to do that, you need to help us understand
- your problem
- your environment
- what you have tried
What PL/SQL Gateway do you refer to? Thus is an old term for an old product - today in Oracle there are two "gateways" into the PL/SQL engine via HTTP. Via Apache/mod_plsql and via the internal Java servlet web engine called EPG inside Oracle.
As for what the "Gateway" access to the PL/SQL engine via HTTP.. whether it supports EXECUTE IMMEDIATE or not is like asking if a car "supports" soft drinks or not (just because a human that may consume soft drinks acts as the driver of the car). Not sensible or relevant at all.
mod_plsql creates an Oracle session to the database instance, and executes a PL/SQL procedure in the database. This is no different from any other client connection to Oracle. Oracle has no clue that the client is mod_plsql and not TOAD or Java or VB or PHP or Perl or whatever else.
So how can this support or not support the EXECUTE IMMEDIATE command? Does PL/SQL support EXECUTE IMMEDIATE? Well duh...
Why do you get a generic 404? Because the PL/SQL call made by mod_plsql failed with an unhandled exception. mod_plsql gets that exception and now what? Was a valid HTP buffer created for it to stream to the web browser? If the buffer perhaps partially completed? All that mod_plsql knows is that it asked for a HTP buffer via that PL/SQL call and it got an exception in return.
A 404 HTTP error is the only reasonable and logical response for it to pass to the web browser in this case.
PS. to see why mod_plsql fail, refer to the access_log and error_log of that Apache httpd server

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}+.

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;
HTTP-Port FTP-Port
80 2100
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:
Failed to Connect

Though the site seems valid, the browser was unable to establish a connection.
* 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'
type='UNKNOWN' level='16' host_id='hostname'

</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:

Three tier (mod pl/sql) vs. two tier (PL/SQL Gateway)

I've been using 10g Database and 10g application server on separate servers for some time now.
Going the two tier (11g) route has some attractions, but what are the disadvantages?
The Oracle documentation I've seen says very little on making the decision, giving benefits as:
Ease of configuration
Included in the database
No separate server installation
- but no negatives.
Does anyone have any real live experience of comparing the two options?
I'm inclined to believe that three tier might have more tuning flexibility, better performance if each tier is on a different server. Maybe worse than two tier if on one server, assuming two tier eliminates communication overheads..
Does pl/sql gateway have the caching ability of Apache/mod pl/sql - I assume not? - that could make a big difference.
Any thoughts would be welcome...

There are several key performance advantages of OHS over EPG. I'm working a lot with the EPG right now and pushing the XDB team to add several of these features (maybe in 11.2, possible backport, but don't count on it). I used recommendations from the yslow Firefox add-in to do some performance tuning. Here's there list of Best Practices:
http://developer.yahoo.com/performance/rules.html
- EPG does not add an "Expires" header. So, lets say you have 25 images in your page template, and none of them change. Each page view will still request those 25 images. They use etags, so you don't have to download the images, but your browser still makes the requests which is quite slow. From my testing, pages could be up to 4 times slower with the EPG with a pretty standard template. The XDB team is aware of this and working hard to resolve it.
- EPG does not support gzip. This is another HUGE performance hit.
Keep in mind you can't test any of those issue with debug mode in APEX, you really need to use a browser plugin such as Firebug + ySlow. The render speed from APEX's point of view will be the same, no matter what HTTP server you use.
The other big on is mod_rewrite support. There is no way easily create friendly URLs for your apps. Another thing to consider is that a number of Identity Management systems, such as Oracle Access Manager (OAM) work by installing an Apache Module or in the case of IIS, some type of plugin (forget what they call it). There is no concept of this in EPG.
IMHO, it's convenient for laptops, but I would never use it for production unless you needed some feature that it exposes, such as WebDav or FTP access to the XDB repository...

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.

PL/SQL gateway in runtime

All,
I created an application in DEV environment (Apex 3.2.0, Oracle 10g, XP, localhost, Language: de).
I imported it into Prod environment (APEX RUNTIME, PL/SQL Gateway, Oracle 11g, Linux) and enabled it.
When I try to access my application via http://192.xxx.xxx.xx/apex I get the message:
‘Page does not exist’.
How can I check the settings of the PL/SQL Gateway?
Or might there be another cause for that prob?
Thanks in advance
lucio

Hi,
thanks for your fast response.
I get the message "ORA-31050: Zugriff abgelehnt", which means I don't have sufficient rights.
Do I need to be sys or is APEX_ADMIN_ROLE sufficient?

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.

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?
Regards
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

PS ... I am using APEX 3.1 with 11g

File Upload and Download in Oracle iAS PL/SQL Gateway

i'm using the example 113471.1 to "File Upload and Download in
Oracle iAS PL/SQL Gateway"
when i press the submit button after i select a file to upload
i get the next message in the browser "No se puede mostrar la
pagina" HTTP 404 file not found.
I think the problem is in ctnsample.upload_form in the line
htp.formOpen(curl => 'cntsample.upload', cmethod => 'POST',
cenctype => 'multipart/form-data');
The ctnsample.remove work fine.
Could you,help me...

There is a document in the Oracle 9iAS 1.0.2.2 Library titled "Using the PL-SQL Gateway" Part Number A90099-01.pdf that explains file upload and download through modplsql. In particular there is a section there titled "Direct BLOB Download" which explains how one can easily download a blob utilising the wpg_docload package.
I am still concerned that there exist duplicate copies of my blob content. One copy in the wwdoc_document$ table, and one in my custom table.
Dmitry/Oracle can you confirm this?

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,

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...

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.
