How to enable MSDOS program to be called from Oracle PL/SQL procedure ( Web Service )?

Hello,
Dealing with the time demanding procedure where power user is interactively execute sequence
of steps of procedure:
1. pl/sql procedure for preparing data in some table
2. java program that read data from the table and creating input txt file for MSDOS program
3. MSDOS program is autonomous component that reads input txt file and make
output txtfile.
MSDOS program is closed component, can not be modified
4. java program that insert txtfile into Oracle table.
5. Steps 1 to 4 are executed in interations driven with select on some table.
Trying to prepare re-design the procedure and not sure about which technologies to use ?
The goal is that whole procedure would be implemented in pl/sql procedure and this way could be executed
so as from power user from command line as from controlled application on any type of the client.
So if that MSDOS program would be transformed as Web Service offered on some MSWin server in the intranet.
Then PL/SQL procedure would communicate ( call this web service ) and do all the job and at the end
send status of completion and report through e-mail to the issuer of the procedure?
Not sure what technologies should I use on Oracle RDBMS server on Linux to communicate with MSWin Web service which is running MSDOS program ?

Yes it can be done. Simply consult the applicable manuals that contains all of the details on how to do it. The manuals are:
- Oracle® Database Application Developer's Guide - Large Objects (refer to Chapter 6 section on Using PL/SQL (DBMS_LOB Package) to Work with LOBs)
- Oracle® Database PL/SQL Packages and Types Reference (refer to the chapter on DBMS_LOB)

Obtaining HTML page by issuing a call from a PL/SQL procedure

Is there any possibility to obtain HTMLDB -> HTML page from a user defined PL/SQL procedure ?
For example I build an procedure which calls directly
flows_010500.wwv_flow.show(null,p_flow_step_id=>'2',p_flow_id=>'104')
and i try to read the result from htp.showpage, but I get a html response page with a security error.
Maybe is necessary to initialize other parameters?
Any help?

My Gf has my iphone. How can I see recent messages and calls from another device?

My Gf has my iphone. How can I see recent messages and calls from another device?

Depending on your carrier, you may be able to see recent calls by logging into your account on the carrier's web site, if they offer such a feature, though incoming calls being shown is not usual. There will, as diesel said, be no way to see messages already received, either SMS/MMS or iMessages, without having the phone.

How to pass variable to content area from a PL/SQL procedure

Hi,
Can somebody tell me how to create a(Content area) folder based on a PL/SQL procedure that takes a variable as a
parameter and returns data based on value of that parameter to the folder . Any help would be appreciated .
Thanks and regards.
Neeti.

Somewhere, in one procedure, build a session identifier and save your variable there. If no session with that identifier is previously stored, it will create a new session instance with that ID for you.
declare
l_sess portal30.wwsto_api_session;
varvalue number;
begin
varvalue := 100;
l_sess := portal30.wwsto_api_session.load_session('MYSESSION','VARIABLES');
l_sess.set_attribute('VAR_NAME',varvalue);
l_sess.save_session;
end;
In your other procedure, or anywhere else needed within that same session, simply load the session and reference the variable. To reference the variable, use the following.
-- assuming new procedure, so re-defining session variable and reloading session into it
declare
my_session portal30.wwsto_api_session;
my_new_variable number;
begin
my_session := portal30.wwsto_api_session.load_session('MYSESSION','VARIABLES');
my_new_variable := my_session.get_attribute_as_number('VAR_NAME');
end;
This will let you reference parameters across multiple portal applications and indirect calls.

Function called by what PL SQL procedure

Hello.
I want to see all the callers of a PL SQL function. I know it is called by some PL SQL procedures in a package. How do I see who calls the function?
Thanks.

i think you can try this : select * from
user_dependencies where type = 'FUNCTION' actually, that what should what things are referenced by your function
and you'd be better off with ALL_DEPENDENCIES, since references can cross schemas.
select name, type from all_dependencies
where referenced_owner= 'ME'
and referenced_name= 'MY_FUNCTION'
and referenced_type ='FUNCTION'
this will show what other things are using your function. if it's used by a package, it will not show the exact procedure or function within that package.

Hi Nicolas!
Have you tried to set "Output Format" for "RAW Text" to HTM in SCOT.
If HTM is missing in your dropdown-list, you could check out table SXCONVERT2. Copy the line with category T/format TXT, and change the format from TXT to HTM. The existing function
SX_OBJECT_CONVERT__T.TXT does not need to be changed. Now you should be able to choose HTM in SCOT. You will probably need som HTML-tags in your text to make it look good.
Hope this helps!

Geir
