Alternative to PLSQL Gateway

Hi !
I'm currently installing an Oracle Database to host our production website coded in PLSQL with HTP package. Currently for development, we are using PLSQL Gateway to publish our pages.
But in production, PLSQL Gateway might be too weak to use it with a lot of visitors. Is there a stronger alternative to expose PLSQL in web pages ?
Thank you !

But in production, PLSQL Gateway might be too weak to use it with a lot of visitors. Is there a stronger alternative to expose PLSQL in web pages ? There are several options:
1. The Embedded PL/SQL Gateway (DBMS_EPG), which is a webserver built into the database itself
2. The Oracle HTTP Server (OHS), which is based on the Apache codebase, with mod_plsql
3. Java-based web servers (such as Tomcat, WebLogic, and others) with the open-source DBPrism plugin, or the upcoming, Oracle-supported Apex Listener
4. And Microsoft Internet Information Server (IIS) with the Thoth Gateway module, see http://code.google.com/p/thoth-gateway/

Can wpg_docload work with the embedded plsql gateway?

Hi,
Looking at all the sample code with wpg_docload.download_file. Put the following in a plsql region, but it does not work. Is it due to my running with the embedded plsql gateway, rather than http server and mod_plsql?
Here's the code. The file exists and is a small 213-byte file.
declare lob_loc bfile;
v_length integer;
fname varchar2(100) := 'x.txt';
begin
lob_loc := bfilename('CELFILES_9906', fname);
v_length := dbms_lob.getlength(lob_loc);
owa_util.mime_header('text/plain', false);
htp.p('Content-length: ' || v_length);
htp.p('Content-Disposition: attachment; filename="' || fname || '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end;
It returns:
"HTTP/1.1 500 Internal Server Error Server: Oracle XML DB/Oracle Database Content-Type: text/html; charset=UTF-8 X-DB-Content-length: 213 Transfer-Encoding: chunked Transfer-Encoding: chunked"
The filesize is correct and if I comment out the call to wpg_docload.download_file I see:
"Content-type: text/plain; charset=UTF-8 Content-length: 213 Content-Disposition: attachment; filename="x.txt""
Thanks.

Hi,
Tried simply doing the grant, but it did not work. Aside from having a bit of trouble with the loadblobfromfile (had to enumerate all 5 parameters) and also having to specifically do a dbms_lob.open, it worked!
Here's the final code that worked:
declare
lob_loc bfile;
v_length integer;
fname varchar2(100) := 'x.txt';
l_blob blob;
des_offset number := 1;
src_offset number := 1;
begin
lob_loc := bfilename('CELFILES_9906', fname);
v_length := dbms_lob.getlength(lob_loc);
DBMS_LOB.createtemporary(l_blob, FALSE);
dbms_lob.open(lob_loc, dbms_lob.lob_readonly);
DBMS_LOB.LOADBLOBFROMFILE(
dest_lob=>l_blob,
src_bfile=>lob_loc,
amount=>v_length,
dest_offset=>des_offset,
src_offset=>src_offset);
owa_util.mime_header('text/plain', false);
htp.p('Content-length: ' || v_length);
htp.p('Content-Disposition: attachment; filename="' || fname || '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( l_blob );
DBMS_LOB.freetemporary(l_blob);
EXCEPTION WHEN OTHERS THEN
DBMS_LOB.freetemporary(l_blob);
RAISE;
end;
Thanks Udo.

Procedure/package to change user password through plsql gateway

I'm not sure is this the right place to ask, but I don't know anywhere better.
I'm using Oracle 817 with the apache that bundled. I use the plsql gateway (mod_plsql). I want to create a page for user to change their password, however, I don't know how to verify the existing password of the user before changing to a new password. Also, how can I change the password, is there a standard procedure to do that?
One more question, when I key in the following:
http://myhost/pls/my_dad/my_schema.my_procedure
the web server return a page with lots of cgi environment (assuming the my_procedure doesn't exist), how can I customise this page?
thx.

To ensure security of the Oracle database system and prevent unauthorized access to the Oracle database, it’s important for Oracle users to not only using strong and long Oracle passwords to avoid brute force or dictionary attacks, but also to change the Oracle user password regularly. Oracle users also have to change the password when the password has or going to expire, if database system administrator implements and enforces strict password control with PASSWORD_LIFE_TIME option for user profiles which limits the number of days the password can be used for authentication to login to the system.
To change the Oracle password, users can use SQL*Plus or Oracle SQL and PL/SQL language interface administration tool such as Toad for Oracle. No matter what SQL apps you use, the commands and SQL query languages used to change the password are similar.
There are two SQL command syntaxes that can be used to change Oracle database user password:
ALTER USER user_name IDENTIFIED BY new_password;or (from Oracle8 and above):
PASSWORD
For above SQL query, if you need to change another user’s password, use the following command:
PASSWORD user_name
For PASSWORD command, after you press Enter, you will be prompted to input the old password and new password interactively. For example:
SQL> password
Changing password for DAVID
Old password:
New password:
Retype new password: Note: You need to have enough privileges to change other Oracle user’s password.
As the variable in italic implied by name, user_name is the user whose password wishes to be changed, and new_password is the new password to assign.
As ALTER USER SQL syntax will send the new password to the Oracle database server unencrypted if use without Advanced Security Option, and thus expose to security risk, Oracle users should always use the PASSWORD command to change the Oracle user password.

Embadded PLSQL Gateway on APEX3.2

Does APEX 3.2 allow usage of Embadded PLSQL Gateway instead of a separate HTTP server on 9i and 10g?
Thanks,
R

Database 11gR1 is the first supported version of the embedded PL/SQL Gateway for Application Express.
The embedded PL/SQL gateway is available in DB 10.2.0.3, but this is not a supported configuration for Application Express.

Embeded PLSQL Gateway & 404 page not found issue

Hi
If I use APEX_ITEM.TEXTAREA with Embeded PL SQL Gateway and submit the page, it throws "HTTP 404-page not found" error.
It doesn't happen when I use apache server instead of EPG.
Our production APEX is down because of this issue.
Any help/suggestions would be greately appreciated.
Here are the simple steps to reproduce the same in a EPG environment.
Note: It works fine in apex.oracle.com [http://apex.oracle.com/pls/otn/f?p=20193:6]
Create a blank page with a report region for the following query. Add a self submit button to it. Run the page and hit the submit button and you will get 404-page not found error.
SELECT APEX_ITEM.TEXTAREA(3, 'a' || lpad('z',1999),3,80) COMMENTS
FROM dual
CONNECT BY ROWNUM <=10
Note:
If you want to see this error in the same browser : exec
dbms_epg.set_dad_attribute('APEX',
*'error-style',*
*'DebugStyle');*
Ref: --blocked::[http://daust.blogspot.com/2008/04/troubleshooting-404-not-found-error-on.html]--

Hi Masa,
I am also facing the same issue. After creating a Target Mapping tile for our custom application, when I save I get the below error :
Configuration changes not saved for tile 'Target Mapping'
Error (404, Not Found) in OData response for PUT "/sap/opu/odata/UI2/PAGE_BUILDER_CUST/PageChipInstances(pageId='X-SAP-UI2-CATALOGPAGE%3Aicch_report',instanceId='00O2THPMYBCTODLKRWF1EBX3F')": HTTP request failed Details: Resource PageChipInstance not found.
I assigned a customizing transport as suggest in your response and saved again, but that did not help either.
The surprising thing is, when our basis consultant (who has SAP_ALL) saves the tiles, he can save them. This tells me that all the necessary services to create/save the tiles are active.
We have tried to trace my userid for missing authorizations - but none was found.
Not sure what is causing the error when I save the tile..

WWW Location of the Novell Client for XP supporting IP Gateway Services

When connecting Windows XP workstations to the SBS 6.0 server through the
Novell Client 4.9SP1a for Windows XP, there are no services within 4.9
for IP Gateway included. As many of you know, by using BorderManager as
the Firewall/NAT/IP/IPX Gateway to access the Internet, all workstations
accessing the Internet need the IP Gateway service installed with the
client. The Novell Client CD-ROM shipped with the Novell SBS 6.0 media
has clients for Windows NT/2000 (outdated) but none are compatible for
Windows XP (it appears that Novell had not updated their Novell SBS 6.0
media since they started shipping it). In addition, the online
documentation included with the media is outdated (e.g. BorderManager 3.6
docs for BorderManager 3.7 being shipped) and do not mention anything
about configuring Windows XP clients for Novell IP Gateway services.
I have thoroughly looked within Novell's Support site the past few weeks
for:
+ The original Novell Client 4.9 (prior to support packs) to see if that
version of the client has IP Gateway services included (file not found or
listed).
+ Previous Novell Clients for Windows XP to see if those versions support
IP Gateway services. (Support Pack versions only are listed, but no
original versions, and do not contain Novell IP Gateway services).
+ Any instructions or tips for configuring the Novell IP Gateway services
within the Novell Client 4.9 or earlier versions for Windows XP(documents
are non-existent).
All of the above leads the following question:
Can someone please direct me to the location to where the proper
Novell Client for Windows XP supporting Novell IP Gateway services?
Since Windows XP has been around for a few years now, one would think
Novell would have developed a client for it that possesses Novell IP
Gateway services by now to be used with BorderManager. Correct? If so,
where is it? In addition, one would think Novell would include the media
supporting the current software they are shipping, not outdated ones.
(Or at least, ensure their outsourced sales services are doing so.) In
addition, one would also think Novell would at least provide the
necessary tools/files necessary to at least to have the ability to
install their products out of the box - instead of forcing their
consumers to purchase unnecessary additional support services for
something they should have included within their media package or website
at the start.
Nevertheless, I appreciate any input where to find the appropriate Novell
Client for Windows XP supporting Novell IP Gateway services.
Thanks,
EricV

This is simply not correct. Novell has not been providing IP gateway
functionality within Client32 for a long time, because it is not needed,
and it had serious limitations.
I haven't had a client using IP Gateway for many years now, and I have a
*lot* of BorderManager clients.
The alternative to IP Gateways is a combination of proxies and NAT w/filter
exceptions.

Gateway Sample

Hey Martin,
It wud be gr8 if U can give some example of enabling Alternative 2 for gateways (Exclusive).
I am facing issue while evaluating condition for gateway...(Alternative2).
Probably using a Scenario as given below would be of much help to me :
A context attibute in webdynpro of type boolean,binded with Check box (stating rejected) on UI.
A exclusive gateway in Process Composer Project,wherein a gateway is used with options as Accepted and Rejected.
Accepted (Alternative 1 ) is my default gate.
In condition evaluation for Alternative 2, how do I go ahead ?

Thanks Earl, but I was interested in anything Oracle might have to say on the subject. I would have expected some basic benchmarking of a sample application to be provided,as XDB/PLSQL Gateway has been plugged at recent conferences as a way forward for APEX implementations.
I've got the basic XDB/PLSQL gateway install setup on Linux, as per the notes at technology.amis.nl, and left the apache installation in place so I can perform a quick comparison.
I've used Firebug 1.0b5 to give me timings, and it seems as though on SUSE Linux 8.1 Oracle 10.2.0.3 Apex 2.2.1 that the Apache server is 2wice as quick at serving up pages as XDB/PLSQL gateway. One particular point to note is that much of the delay seems to be in the handling of the f package.
Has any-one any comment to make ?
Cheers, Mark.
PS the Apache install is pretty much out-of the box, and it's the version which ships on the Oracle Companion disk.

SSL encryption for Apex 4.1

Hi Guys,
I am trying to set up SSL encryption for my local install.
I am running APEX 4.1 in Windows 7 (32 bit) , Oracle XE 11G with embedded plsql gateway setup.
The APEX documentation I looked at that deals with SSL:
http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21678/adm_mg_service_set.htm#AEADM297
instructs to turn HTTPS on in APEX_ADMIN (Internal schema) under security.
It didn't work as APEX was visible still under http://localhost:8080/apex and using HTTPS gave page not found error. On top of that It locked out my Admin account for INTERNAL workspace. So I had to switch it back via SQL query in SQL plus.
From limited experience in doing something similar in Tomcat, I believe one needs certificates etc before proceeding with this.
Anyone who has done this before, can you please point to a any documenation/blog post, tutorial etc that shows how its done? Many thanks.

Pls help!Can Oracle v7 support WebSphere Application Server instead of Oracle 8i

Hi,
I am using WebSphere as my application server and NT4.0 as OS.
I wish to connect to Oracle db which is located at another server.
Currently what I have is Oracle Client Software v7.3.4. There is error when I want to start the service.
So I suspect that it is not compatible and it might require Oracle 8i in web environmt and to support WebSphere Application Server as well.
Can anybody help me? Thank you.

Hello,
I guess you could get that to work as somebody was able to use WebLogic as webserver: http://christopherbeck.wordpress.com/2008/09/15/weblogic-server-and-apex/
Alternatively you could use the Embedded PLSQL Gateway if you don't want to install Apache (depending database version you are on).

Can you help me solve my Leopard Server VPN madness?

Hello all,
I've been having a devil of a time getting Leopard Server's VPN service to work "properly". None of this is mission critical, as it's simply on a home system I'm using as a nat/dns/dhcp/firewall/mail/web server for my Comcast line (with a static IP). But, it is frustrating, because I currently have a 10.4.11 Server fulfilling the same roll. So it seems like Leopard should be able to be made to work. I'm gonna go step by step here with my install process in the hopes that if I'm doing something wrong someone will be kind enough to catch it. Thanks for bearing with me.
I've installed Leopard Server 10.5 (Mirror door G4, FYI) with the built-in ethernet connected to my Comcast router (with a static external IP). Immediately after 10.5 installs I restart and update everything to 10.5.2, then I install a Sonnet Gigabit NIC, it's drivers, and assign it 192.168.3.1, where it will live as my internal router, server, etc. I turn on DNS and setup an internal ".lan" zone that resolves to 192.168.3.1. Pop into Terminal and confirm that rDNS is in fact working, it is. And check that "changeip -checkhostname" resolves itself correctly (to the external IP).
Next, turn on the NAT service and run the gateway setup assistant. After a reboot I quickly check that my internal clients with static IPs (192.168.3.10, .20, etc) are working and pulling DNS OK, they are. Jump into the Firewall, and for the moment just open it wide up by accepting all connections. At various times during testing I've configured the firewall to exactly match my 10.4 Server firewall, but for the time being I can just leave it open. I create a Firewall group to cover my 192.168.3.x internal network, and another to handle 192.168.3.60/29 to handle the VPN service I'll setup in a sec. Jump over to the DHCP service where by default gateway setup creates a 192.168.1.x DHCP zone. I delete that and create a new 192.168.3.x zone covering .50-.59. Turn DHCP on and confirm it's working, good, it is.
Now, here is where the VPN fun begins. The last service I turn on is the VPN service (I've alternatively tried letting Gateway Setup activate it, and just doing it myself, with this same result). I configure it to accept L2TP at 192.168.3.60 - .63. Like I said this is a home server, so I don't need a lot of VPN connections. Finally, when I test the VPN from a 10.5.2 Client (MacBook coming in off a neighbors open wireless network with a 10.0.0.x string) I am able to connect, and I can see/ping/mount/share screen on the server. I can also ping the attached VPN client at 192.168.3.60 from the server. However, I cannot ping or see (In ARD) any other machines on the internal network from the attached VPN client. Likewise from one of the internal systems, say my Mac mini at 192.168.3.10 I cannot ping the attached VPN client at 192.168.3.60. Out of curiosity I've tried doing a rDNS lookup while attached to the VPN and the client isn't able to resolve any of the internal DNS entries.
So, what gives? As I've mentioned I have exactly this same setup working just fine with Tiger Server. Same NAT, same Firewall, same DNS, and same L2TP VPN setup. For the life of me though, I cannot get attached VPN clients to see the internal network when I put Leopard Server in place. Clearly the internal DNS isn't working for attached VPN clients, although I'm not certain if that is a cause or a symptom. I've setup a network routing definition for the internal private network, which didn't help. I also tried setting up PPTP instead of L2TP, and had the same problem.
Is anyone having similar problems with Leopard Server's VPN service? If not, could someone hit me with the clue stick and set me right? As I said, in the grand scheme of things this isn't a big deal for me. But, it's just frustrating that I can get so close to updating my home server and just fall short.
Thanks!

Your post actually contains the Key to solve the problem and there is not really a big need for going all the way to use the Property List Editor to fork around /etc/ipfilter/ipaddressgroups.plist.
There has been much written on this problem but basically you see that most is trial and error and this does include myself and my findings in this post, too, but I think I can further narrow down on what CAUSES this problem and how to fix it.
First off, we are talking a combination of using NAT (Network Address Translation - bridging an Internet connection on an external network card over to an internal network card), Firewall (which is needed in OS X to be have NAT working because the Firewall "helps" NAT by doing its job, DHCP (for providing dynamic IP addresses to clients on the internal network, don't confuse, DHCP is not providing this service to the VPN clients, that is done by the VPN server), and - last but not least - VPN to provide access to not only to the server but to any machine on the internal network over the outside network card (aka, giving remote clients a chance to connect to the local network over the public Internet in a save and nice way).
OK. The short story: you can do it ALL in Mac OS X 10.5's Server Admin tool. If it fails it is nearly always the Firewall!
You can check if this is the case for your setup by temporarily opening the Firewall up to not block any traffic: in Server Admin, click on Firewall -> Settings -> Services -> Edit Service for: any and click "Allow all trafic from "any"", save it (and to be 100% sure, stop and restart the firewall. If your clients can NOW connect at least to the server, it was the firewall. Now don't forget to switch off allowing all traffic from any, or you will be left with an open doors server ready for anybody to explore
Now what goes wrong in the first place? It appears that the GSA (Gateway Setup Assistant) that is "hidden away" in the NAT settings does something awfully wrong. It will set up all the address groups in the firewall: the any group will remain as it is usually, another one defining the internal network, and a one called VPN-net for VPN.
What it DOES do wrong here (I am no firewall expert, this is purely trial and error, so please anybody do explain!) is to give the VPN-net exactly the same address range as the internal network. And here seems to be the overall problem.
When Twintails wrote to add 192.168.3.60/27 as address range for VPN, I realized what he/she did. Writing 192.168.3.60/27 effectively narrows down the address range starting at 192.168.3.33 up to 192.168.3.62. There are millions of subnetmask calculators out on the net, give it a try e.g. here: http://www.subnet-calculator.com/
So, I looked for what range of address will actually be given out by the VPN server to VPN clients upon connections. Of course you need to make sure that this address range is NOT given out by your DHCP server.
In my setup, the server is 192.168.1.1, the DHCP server provides addresses from 192.168.1.10 up to 192.168.1.127 (I start with 10 because I have some static addresses for special purposes from 192.168.1.2 to 192.168.1.9. So, this means, anything above 192.168.1.127 is potentially "free" for my VPN connections.
Next I used the subnetmask calculator to find a narrow address group that matched my purposes. I found 192.168.1.192/26 which effectively gives me a range from 192.168.1.192 to 192.168.1.255 (which is in fact more then I have clients connecting from externally!).
I went to the Server Admin Tool, and clicked Firewall -> Settings -> Address Group and edited the VPN-net one. First I deleted what was in "Addresses in group" and entered from scratch 192.168.1.192/26. Next - just to make certain because basically this is what Twintails had in his/her post by saying to add a name String with exactly the same information - I overwrote VPN-net by 192.168.1.192/26 and saved. (I THINK that this last step might not really be needed, but I haven't tried).
Next click Save (basically it should already work, but I always want to be extra sure, so I stoped and immediately thereafter started the firewall again to be 100% certain all new rules are now active.
And now: it works! Clients can access the server AND the entire local network from remote using VPN.
One last comment: I have the feeling that (although less safe and less advanced technologicall) PPTP works much better for us then L2TP. So I have switched off L2TP support altogether because it simply NEVER really worked. We are using Mac OS X 10.4 and 10.5 to connect to the 10.5 server using this setup.

Apex 3.1.2 installation on Oracle 10g Standard Edition (10gSE)

Hi..We're trying to install apex 3.1.2 on 10gSE (No application server 10gAS is available but just the database).
Can it be installed with the embedded plsql gateway (EPG) option?
or
Oracle HTTP Server mod_plsql option?
Currently there's Apache webserver already running on the box with PHP applications running. Want to make sure that apex/http-server install will not corrupt the existing environment.
Please provide any pointers/references. IF YOU CAN OFFER PHONE SUPPORT FOR 1-2 HOURS, YOUR TIME IS Sincerely APPRECIATED. PLEASE EMAIL: [email protected] For Direct contact. Also, I may need help to solve some apex screen issues.
* Removing the tagging with $ compensation on the post..Apex Community as in the past has been extremely helpful in solving many great apex challenges. Thanks for the continued support. *

1- Here is what I mean, the oracle website is showing Web Logic in the download page of oracle application server:
http://www.oracle.com/technology/software/products/ias/index.html
Is there a separate download link for Oracle Application Server, if it's different from the web logic server?
2- I Installed HTML_DB which is found in the Oracle 10g companion CD, I think I installed the HTTP Server with it, but now I want to install APEX 3.1.2 which I downloaded separately, if I uninstalled the HTML_DB using Oracle Universal Installer, will it remove the HTTP Server as well? since it lists the HTML_DB only as being installed without listing the HTTP Server separetly.
Thanks.

Test program으로 JVM test해보기
Java Stored Procedure 만들기
다음과 같은 순서로 Java Stored Procedure를 만들어 봅니다.
1. Java program을 만듭니다.
2. program을 database로 loading합니다.
3. Java program을 SQL (PL/SQL Wrapper)로 publish합니다.
4. SQL 또는 PL/SQL에서 만든 Java program을 호출합니다.
Step 1: Java program을 만듭니다.
======
EchoInput.java
public class EchoInput {
public static void main (String[] args){
for (int i=0; i<args.length;i++)
System.out.println(args);}}
Step 2: program을 database로 loading합니다.
======
UNIX prompt상에서 다음을 실행합니다:
% loadjava -u scott/tiger -v -r EchoInput.java
또는 SQL*Plus에서는 다음과 같이 할 수도 있습니다:
CREATE OR REPLACE JAVA SOURCE NAMED "EchoInput" AS
public class EchoInput { public static void main (String[] args) {
for (int i=0; i<args.length;i++) System.out.println(args[i]);}}
Step 3: Java program을 SQL (PL/SQL Wrapper)로 publish합니다.
======
SQL 또는 PL/SQL에서 만든 Java program을 호출하기 위해서는
Java program을 SQL (PL/SQL Wrapper)로 publish해야 합니다.
이과정을 PL/SQL Wrapper를 만든다고도 합니다.
일단 published/wrapped가 되면 SQL 또는 PL/SQL을 통해 호출될 수
있습니다.
예제 :
create or replace procedure echo_input (
s1 varchar2, s2 varchar2, s3 varchar2)
as language Java
name 'EchoInput.main(java.lang.String[])';
Step 4: SQL 또는 PL/SQL에서 만든 Java program을 호출합니다.
======
call dbms_java.set_output(5000);
call echo_input('It', 'works', 'now!');
주의 : SQL*Plus에서 실행할 경우 먼저 'set serveroutput on'을
해주시기 바랍니다.
결과 화면
SQL> set serveroutput on

Integrating Google Maps in Oracle Apex and 404 Not found error page

Currently using APEX version 3.2.0.00.27 installed in OracleXE version 10.2.0.1.0. Have been attempting to recreate some examples of Google Maps within APEX. Found a nice set of examples here that build up to what I'm looking to ultimately do by incorporating google maps into APEX:
http://blog.whitehorses.nl/2009/10/04/integrating-google-maps-in-oracle-apex/
Unfortunatly, I'm getting the "404 Not Found, Not found, The requested URL /apex/wwv_flow.accept was not found on this server" page when I try to recreate the "Map with Search" example. I'd like to see if this really works using the html input and button tags in the body/region source versus creating APEX items to pass the address values to the javascript in the html header of the apex page. I'm thinking it's just an html thing within APEX that you have to do it a certain way, but I haven't managed to hit that magic combination. have gone to the google maps api v2 and looked at the html they use (it's what these examples with apex are based on) and tried that just to see. Same 404 result.
I've seen suggestions at this forum and elsewhere that the 404 error is due to a bug. have been to metalink, and really haven't seen anything that spells out what the bug is and how to patch it or work around it. May be I just haven't found the right note/doc yet. have seen suggestions to change something associated with the Anonymous account that APEX uses. Have turned on authentication in the application to use an APEX user account with a logon page to the application. Still get the 404. Although, I have not adjusted anything elsewhere, like a DADS config file, because the apex/xe configuration is using the plsql gateway. Not sure of any procedure for changing settings on anonymous account when using plsql gateway.
Open to suggestions. APEX 3.2 is customer version, so going to 4 may not be an option yet. XE, on the other hand, can certainly be swapped for an 11g version standard or enterprise edition if need be. I don't think this is a db version problem though. I think it's more on the APEX side of things.
Anyway, any help or suggestions are appreciated.
thanks

Java Stored Procedure via Function Give 0RA 600 from SQL Workshop and App

Hi,
Anyone experienced stored procedures or functions failing when called from APEX app or SQL Workshop ( ora 600 ) yet they work fine when called from SQLPlus?
Sqlplus connected as my apex workspace schema owner:
select net_services.test_db_connection_via_ldap(
'APEXPRD1', 'test1', 'test1', null ) as result from dual;
RESULT
The database connection attempt was SUCCESSFUL
From Apex Sql Worshop:
select net_services.test_db_connection_via_ldap(
'APEXPRD1', 'test1', 'test1', null ) as result from dual;
ORA-00600: internal error code, arguments: [16371], [0x434B08150], [0], [], [], [], [], [], [], [], [], []
NOTE: Same result when run in response to button push on page in application.
Apex Version: 3.2.1.00.10
Oracle Version: 11.1.0.7.0
NOTE: I am using the embedded plsql gateway; was going to try NOT using it to see if it was shared server related (seemed to be from trc files)
Any ideas?
Since the code works from sqlplus, I know that it's good: Here some snippets
-- ========================================================================================
public class NetServices extends Object {
public static String doTestDbConnectionViaLdap
String piDbConnUrl,
String piUserName,
String piUserPassword
     String vResult = null;
