Query about granting access from another PC to my application (PC)

Hi everyone,
I have developed an application on APEX using the following background.
1. Windows XP
2. Oracle Database 11g
3. Application Express 3.0.1.00.08.
4. The architecture I installed was the embedded PL/SQL gateway one, which "provides the Oracle database with a Web server and also the necessary infrastructure to create dynamic applications. The embedded PL/SQL gateway runs in the XML DB HTTP server in the Oracle database and includes the core features of mod_plsql, but does not require the Oracle HTTP Server powered by Apache. Inclusion of the embedded PL/SQL gateway simplifies the architecture and eliminates the middle tier entirely"
I have already configured or at least think so reviewing the post installation tasks:
http://download.oracle.com/docs/cd/B28359_01/install.111/b32006/postcfg.htm#CHDEIGGI
I do mention this because of the: Configuring the Embedded PL/SQL Gateway in New Installation and Enabling the Oracle XML DB HTTP Server
Well the big picture about my app is this; I want to grant my mates the access to my machine throughout this URL:
I have done several try outs on my own machine and detected that if I put localhost, 127.0.0.1 works out very well, but when I put my own IP cant access to it…
http://localhost:8081/apex/f?p=129 works well
http://127.0.0.1:8081/apex/f?p=129 works well
http://10.179.15.39:8081/apex/f?p=129 doesn’t work.
The weirdest thing of it, is that I can access the database
https://localhost:1158/em/console/logon/logon works well
https:// 10.179.15.39:1158/em/console/logon/logon works well
So I thought about a port conflicts at first I had the 8888 port assigned to my application, but afterwards I decided to change it to 8081, but a message appeared…
Network Error (tcp_error)
A communication error occurred: "No route to host" The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
For assistance, contact your network support team.
I will appreciate if anyone can give me some advice… I went to OTN forums and haven’t found a proper answer to my needs….
Best regards.
Jaison González.

Hi, everyone…
As I mentioned before I have been having some issues in granting remote access to my application, and right now I am kind of lost.
What I have done is this:
I can acces to my application with my IP address
Now I have installed on muy PC Oracle Databasee 10g R2 (10.2) EE
Companion (http server)
APEX 3.0
I moved form 11g to 10g, because apparently there wasn’t that much of info about it… bhut when I first installed I at least cand access remotly to my 11g database, but now I can not even do that….
I will appreciate if anyone can help me out with this…

My ipod has been accessed from another ipod and now it won't let me download anything what do i do

my ipod account has been accessed from another ipod and now it won't let me download anything...What Do I do?

Not sure what you are talking about.
Your ITUNES account can be accessed from any device or computer that has itunes, as long as you have your username and password. Using your itunes account from another device does not affect your ability to use the account from your device.
What is the issue?
You tried to do what?
And what was the result?
Error message?

I have an iTunes account where I have downloaded Digital movies & I am able to see the list on the desktop of the original downloads. When I log on another device with my login I do not see my list to access them. Why can't I access from another device

Hey GingCarv,
Great question. You'll want to download the movies from your purchase history. The following article explains how to do so:

Note: At this time, movies are not available for automatic downloads.

Query a second form from another form by passing value

Hi,
I have two forms. I am trying to query a second form from another form. I have managed to display the query results in the second form by passing value from the first form. I did it according to the details in the Oracle 9ias Portal Technical FAQ html file.
It works fine when there is already a row in the first form. When I insert a new row in the first form and query the second form which has key from the first form, there is no matching rows displayed which is correct but detail action mode is 'NONE' for all detail rows.
According to the FAQ, it says the following:-
"When the called form is started, it executes a query with the supplied condition (in this case, "where deptno=10"). If the query is successful, the matching rows are displayed in Update mode. If no matching rows are found, the form starts in Insert mode."
It does not happen for me. I get NONE mode for no matching rows. Is this a BUG ? I am working on Portal version 3.0.9.8.0.
Is there something wrong in the code I wrote ? I would like to have all the detail mode as Insert.
Here is the following code I wrote on SUCCESSFUL SUBMISSION OF THE FORM.
declare
my_url varchar2(1000);
v_deptno number;
begin
v_deptno := p_session.get_value_as_NUMBER(p_block_name => 'DEFAULT', p_attribute_name => 'A_DEPTNO');
my_url := 'PORTAL30.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=1268491962&p_arg_names=_show_header&p_arg_values=YES&p_arg_names=deptno&p_arg_values='||LTRIM(TO_CHAR(v_deptno))||'&p_arg_names=_deptno_cond&p_arg_values=%3D';
go(my_url);
end;

Hi,
The behaviour is OK as in the MD form there are two states "Save" and "Query and Save" and when the form is in "Query and Save" mode that means you can use it for both Query aswell as Save which is decided by your "Master action" if that is None it is used for Query , for Insert you will have to select Insert ,this is the Insert Mode behavior.
If you open a new MD form that is also in the "Query and Save" the same behaviour will be there.
Hope this answers your query.

Client returns server not found:rtmp://192.168.10.1:/live when accessed from another pc

Hi there. Please i have a small LAN of about 8 computers all of which are running windows 7. I have installed FMS and XAMPP webserver on one of the machines. I want to stream live from one PC to all the other PCs on the LAN. I have a webpage with jwplayer embedded in it on my XAMPP webserver that is able to see the live stream when i start it locally. I mean the live stream works fine on the machine with the servers on it. But when i want to view the live stream from another machine in the LAN by accessing the webpage that has the jwpalyer from another machine, The jwplayer returns "server not found:rtmp://192.168.10.1/live" error. I was thinking that maybe a firewall is blocking the 1935 port but i have turned off the firewall of every PC on the LAN. I have unistalled any antivirus program on all the PCs. But i still get the same error when i try to access the live stream from another PC on the LAN.
When i run netstat -a -n|find ":1935" i get 192.168.10.2:49184   192.168.10.1:1935     SYN_SENT and i think the request for the stream is sent but the conection is rejected.
This is the code for the webpage with jwplayer embedded in it. maybe it can help:

This page is able to view the stream on my local machine but it wouldn't work on the other machines on the machines. Is it not possible to stream over a LAN or what? OR What am i not doing right. [hmmn! [sighs] this is so frustrating]. help me please.Thanks in advance for your help.

Thanks man. that is so helpful. But i doesn't solve the problem yet. I'll appreciate it a great deal if you could help me make the server accept requests from the 1935 port... And please tell me whether by server, u mean the FMS or the entire server on which the FMS is installed. I'm guessing it is the latter. Thanks in advance for your help

Re:iMac remotely accessed from another computer and location?

Can you access an iMac remotely from another computer and location if there is knowone to switch it on?

Barbara,
Both are legitimate concerns, I'll address each as best I can.
As for the the power issue, well that's going to be the case with any computer. We have many choices, most of them impractical for example take your house off the grid, put in your own power source (solar or wind powered) which clearly for most of us is totally impractical. The next thing would be a backup-generator like a hospital or other mission critical facilities (police & fire houses) have. While this is more practical again it's stretching the limits again for most of us. So the next thing is a healthy battery back up system that can maintain power to a computer for several hours if necessary. While they are still expensive they are far less expensive than the first two solutions. Of course you can set the energy saver settings to power on your computer after the power comes back on if even the UPS battery goes dead. I haven't tried this remotely however I think it might work.
Next is security, DropBox and Logmein both address this themselves so I would recommend looking into their solutions. Personally I find them trust worthy and don't have an issue. Even if you use MobileMe you would still have the same concerns, and how about Google, and all the other major players. To me Google while it's a vast resource and extremely helpful if for some reason they decided to become the Evil Empire they have far more access to your information that anything. Anytime you do a simple search they are collecting information about you. For example let's say you are looking for ATM's in a new city, they can capture your search and if they were evil enough they could track your every step. Is this far fetched and ridiculous, of course it is but it is possible. However this is the case with any Internet based computing, if you use some basic common sense for the most part your data is pretty secure. I'm much more nervous about the minimum wage clerk at Taco Bell taking my credit card information than Google, Apple, Logmein or Dropbox doing so.

Named instance cannot be accessed from another computer after IP address changed

Hello
In our SQL server computer, we are using dynamic IP. There are two instances; one of them is a named instance.
We can access both instances.
However, after changing the SQL server computer to static ip, we cannot access the named instance from another computer (the non-named instance is ok). Any idea what to do to make the named instance accessible? After the ip address changed, I
only did a ipconfig /renew without rebooting the computer, would rebooting solve it?
Since I only have limited amount of time to take the production server offline and since I do not know enough about this, I ask to see if any one has any idea.
Thanks

Hello,
Please try to restart SQL Server service instead using SQL Server Configuration Manager.
Hope this helps.

What about ftp-access from www?

Hi folks,
first I want to say, I browsed the forum since May 08.
Second please excuse my English.
I'm still trying to set up TC for FTP access from www.
afp works but what about ftp? -
I talk about ftp (RFC959) described in 1985! Why it does not work in a 2008 manufactured product?
I do not demand sftp but I never heard about a company that sells networking products which do not support ftp forwarding...
Apple -that's poor performance.
Hundreds of users are still waiting for firmware update.
Please publish the firmware, if your lack of resources doesn't allow to solve this problem!
Does anybody has an idea to access TC from WAN?
<Edited by Moderator>
Thx

As you have mentioned that your ISP is an DSL provider, Login to the setup page of your Router and click on the status tab and check if the Internet IP address.
Have you enable the FTP feature on your Router? If not then login to the setup page of your Router and click on the storage tab and below Enable "FTP Server" and let the FTP Port be 21 and below select the folder which you want to access it from Internet and click on save settings... Then click on the Administration tab and check for the "Server Internet IP Address" and also below check if Anonymous FTP access is it Enable or Disable.If you wish to allow anonymous Internet access then you need to Enable it or let it be Disable and click on save settings...
To access your FTP server from Internet note down the WAN IP, So it should be ftp://ftp.wan-ip:21. This should allow you to access your drive from the remote location.

Help, account has been accessed from another machine or device ?

Is there anyway to see what machine or device my account is being accessed from ? I got this warning when I was trying to purchase an app on the itunes store.."Your account has been accessed from a new computer or device, and you must verify your payment information beofre you can make purchases" Is there a way to see a list of ip addresses or something to see who's been accessing my acount ?

Need a Query to update table from another table.

I have two tables Table A and Table B , till now in table “A”. I have a column which consist of IDs and duplicate IDs( which are basically formed by Original Ids) , I have another table i.e. table “B” , which gives a mapping between original ids and duplicate Ids
TABLE A:
ID/DUPLICATEID      NAME
1     Rahul
1_CAD     Pawan
2     Nikhil
3     TOM
3_CAD     Ravi
3_MQ     Puneet
TABLE B:
ORIGINALID     DUPLICATEID
1     1_CAD
3     3_CAD
3     3_MQ
Now I want to have another column in Table “A” , which will give me the mapping between the original Id and duplicate Id as shown in updated table “A”.
UPDATED TABLE A:
ID/DUPLICATEID     NAME     ORIGINAL_ID
1     Rahul
1_CAD     Pawan
2     Nikhil
3     TOM
3_CAD      Ravi
3_MQ     Puneet
Now I want to write a Query in which I can update this column (ORIGINAL_ID) of Table “A”, from the table B(basically want to update mulitple rows using single query), because table B already has this mapping. Can any one help me in this. I am basically a Java guy , so I don’t know much about it. I hope to get a positive response from you people, Thanks in advance!

BI query to be accessed from Web Dynpro Java

Hello,
I have a requirement to access a url that fetches data from BI.
The BI query provides output as an xml file when the query is run in a browser and required authentication credentials are provided.
I do not wish to use the standard BEx iView approach available in portal.
Any clue how this can be achieved ??
Thanks in advance.
Regards,
Sudeep

Hi Avik,
I imported the project 3-4 times already, moreover I created a fresh project also. Same outcome.
I am executing the BAPI also. Just now I had restarted the Java Server, let see will that work, this might be pointing to some other server coz I originally configured with other server but shifted to another which i am using right now.
will get back to you if solution achieved. Thanks.

Beginner question about granting access rights

Hi, am a total beginner, just a very simple question. I have created a number of tables with my admin account that I would like user accounts to be able to see (they should only be allowed to see these few tables)
I then created a user account called EDWARD with just the basic connect access right (I don't want them to be able to create/delete tables etc, just to be able to query the tables I have created above and to add rows to these tables)
Google searching has lead me to the grant statement, so I tried this from the admin account:
grant select, update, insert on CUSTOMERS to EDWARD;
This statement executes correctly but when I log in the EDWARD account I cannot do any of these things, instead I get the error: ORA-00942: table or view does not exist
Any ideas?
Thanks

>>Would it be better to create a separate account called 'ADMIN' perhaps that I use for
my application admin and then grant them appropriate access to confidential tables
rather than logging them in as the SYSTEM?
Yes, this is what I would advise, since SYSTEM (like SYS and several others...) is not user like other, it's better do not work and create object under this one. Keep it for Oracle administration usage only, not for application administration, create your own schema for this.

Can dreamweaver be installed on my cloud disk for access from another computer?

I sometimes need to work at the clients office. Can I install Dreamweaver and Photoshop on my Cloud disk for access remotely?

Products such as Dreameaver are still desktop applications and as such need to be installed on a computer. They do not run from the Creative Cloud website.
You could ask permission of your client to install Dreamweaver on their computer. And then before you leave for the day from the menu choose Help > Sign Out to deactivate your subsscription. Once done with that client you could uninstall Dreamweaver from the computer.
Less invasive solutions to working with the client would be to use a solution like LogMeIn (https://secure.logmein.com/), Windows Remote Desktop or VNC to remote into your computer. Here is one article article covering this http://www.wikihow.com/Access-Another-Computer-from-Your-Computer.

Apex access from another interface

Hi,
Greetings.
Is it possible to access a table in my work space and schema in Apex (after validating) using another custom made front-end interface?
Awaiting your responses.
Thanks in advance.

Dear Tony,
Greetings.
I shall explain the situation.
I have to create an application with a small data grid or even a table which has a trigger or lock of certain columns (which cannot be updated more than once, or has the timestamp of the last update).
I am planning to use Oracle Apex as my database as the hosting is free and the it will be used only by a very small number of users. The question is, how do I create a user friendly interface for the non-technical users to access this table on mine to update only the cell/columns they have access to?
Is there an option to create such an application in Apex? I am finding it difficult to define access levels as I have to depend on my workspace authentication scheme since I don't have a LDAP directory or a SSO to link to.Here's one idea - think about if it can work for you.
Create pages in the existing application (probably better) for the non-techincal users where you control the interface.
A new table table should have access levels and username data for the affected users. You can create a maintenance page for yourself to use or just use SQL, whatever is easier. The new pages and their access links should use conditional logic to only render for the users in your table as identified by their login substituion string, probably :APP_USER (check this).
