Hints in Oracle Forms

HI, I would like to indentify all the forms using some type of index in the sql queries. We are upgrading to 10 database running Oracle applications 11.5.10.2.
We are on Linux x86-64. Apprecaite if anybody have any script to do that.
Thanks
Robert

I don't have a forms server on hand, but you can try if they are readable by the 'grep' command, for example:
grep -i "select * from dual" *would, if the forms sources are grepable, reveal all files with "select * from dual" in them.
(of course this needs to be done in the directory in which the forms sources are present)
but please mind I can't test, so it's also possible the queries are not grepable, which means nothing is shown.

Display Hint Text in Oracle Forms 6i at Text Item

Dear all seniors
I want to show Hint text at Text Item in Oracle Forms 6i.
when my cursor Focus goes at that item. I mean when I go with Tab key or Enter button then it show display text.
even though my mouse is not on that item.
please how it would be possible
thanks.
G.Y

Please create a display_item(for eg. Disp_Mess) just below the text field (For eg:-MyField) where you want to show hint. And then assighn Hint text to "DISP_MESS" in NEW-FORM-INSTANCE or at Initial value. Then create a PRE-TEXT-ITEM and POST-TEXT-ITEM trigger for MyField.
-- PRE-TEXT-ITEM trigger write following code.
SET_ITEM_PROPERTY('DISP_MESS',VISIBLE,PROPERTY_TRUE);
--POST-TEXT-ITEM write following code.
SET_ITEM_PROPERTY('DISP_MESS',VISIBLE,PROPERTY_FALSE);
It will work for you.

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,
    created_dt                     DATE NOT NULL,
    case_id                        NUMBER NOT NULL,
    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.

Problem using views containing xpath expressions with Oracle Forms

Mark,
Nice to see you back on the forum answering questions.
This example is based on the standard purchaseorder schema.
i registered the schema, created a relational table and then created
a view using xpath.everything works well and i am able to select the data
using sql*plus. Now this views is like any other view, when i describe the
view, i can see the all the data types are valid for the columns and also the lengths.
Now when i try to base a data block in oracle forms using this view, i get error
"ORA-24324 - service handle not initialized."
Whereas if i create another view on top of the first view and then base the data block on this view, it works for me. i described the second view from sql*plus and everything seems to be same for me.
this is the same behaviour from database 9i r2 and it exists in 10g r1 also.
Any hints as what might be the problem or you would like me to file a tar for this.
create or replace view purchaseorder_header_xml
as
select id
       ,extractvalue(xml_data, '/PurchaseOrder/Reference') reference
       ,extractvalue(xml_data, '/PurchaseOrder/Requestor') requestor
       ,extractvalue(xml_data, '/PurchaseOrder/User')      po_user
       ,extractvalue(xml_data, '/PurchaseOrder/CostCenter') costcenter
       ,extractvalue(xml_data, '/PurchaseOrder/SpecialInstructions') spl_instructions
from tab_xmldata
create or replace view purchaseorder_header
as select * from purchaseorder_header_xml
/Raghu

Not used Forms for years. However I suspect that Forms is trying to poke around behind the view and not understanding what it sees. I expect you'll need to open a Forms Tar to get to the bottom of this. It also appears that you a workaround which is to create a view on the view by the sound of it..

Problem about using Oracle Form 6i to connect Oracle Database 10g express.

Sorry to interrupt all of you.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the paramater of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
After I google it, I still have no idea how to solve the problem. I would like to ask, could anyone mind providing some hints or solution to address the issues.
Thanks for your assistance in advance.

I don't believe the Net8 Easy Config (NEC) will create a compatible entry in the tnsnames.ora. I have Forms 6i running successfully against a 10g Express database, but I did not use the NEC - I created the entry myself. Here is the entry I use:
XE=
(DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=<<servername or IP address>>)
      (PORT=1521)
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=XE)
)Hope this helps,

Calling web service from oracle forms 10g

Problem Description:
I'm following the steps as per the doc:
http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://gend:83/DesignService.svc?wsdl
The service was developed by us.
Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
The code from oracle form to call web service is as below:
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(2000);
ex ora_java.jobject;
str varchar2(100);
BEGIN
jo := GendServiceClient.new;
rv := GendServiceClient.sendHello('Nora');
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;
Any help/ideas on this is greatly appreciated. Thanks.
Edited by: KE Nora Loera on Jun 1, 2012 1:24 PM

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.
Thanks

Unable to do UPDATE in Oracle Form 10.1.2

Hi,
I am using an LOV to query data from a master-type table.
-- WHEN-BUTTON-PRESSED in button Retrieve
declare
l_number number;
a_value_chosen boolean;
begin
a_value_chosen := Show_LOV('LOV_CUSTOMER');
if not a_value_chosen then
message('No value selected');
raise form_trigger_failure;
end if;
end;First, I choose a value from the LOV. The LOV showed the selected items in the Form.
Next, I modified some values (not the Primary Key) in the Form text items.
Finally, I tried to Save the modification into table, using
-- WHEN-BUTTON-PRESSED in button Save
commit_form;
clear_form;Surprisely, it showed
FRM-40508: ORACLE error, unable to INSERT record.
BTW,
Previuosly, I can do UPDATE if I use the Enter Query and Execute Query button.
I did not attempt to do inserting, just updating.
Could someone show where is the problem?
Is the form status not changed by the query returned from LOV?
Any help would be grateful.
Many thanks,
Imelda

Hi,
Glad I found all of you in this forum.
Thanks for all of the explanations.
I thought by using LOV would suppress the network traffic.
If the use of LOV would give lots of drawbacks, then I should see the Enter_Query() Execute_Query() instead.
BTW,
I found the button Enter Query and Execute Query on the toolbar.
(Seems that Oracle Form provides lots of help to simplify the programming)
I have some sort of problems in using them :
1. Well, they do the query and retrieve the records for a match query criteria.
But it did not give any specific message if the record does not exist.
The message bar (for unknown reason) is showing
"Enter a query; press CTRL+F11 to execute, F4 to cancel."
Can we change this behaviour?
Perhaps, showing "No record(s) are retrieved for this query. Either change the query criteria; press CTRL+F11 to execute, F4 to cancel."
2. I found the Count Hits from Query menu.
Based on the documentation, the message line will show the records number returned based on query
criteria, without actually retruning the records to the user.
I am not sure whether this function has been removed for the Oracle Developer 10g (10.1.2), since
there is nothing happen, and the message line keep showing
"Enter a query; press CTRL+F11 to execute, F4 to cancel."
Do we tho do some modification to the Forms to use Count Hits?
3. I read on the documentation about Query Where dialog box.
Query Where will be showed if user enter a colon ':' in a field in Enter Query mode for query criteria.
Again, I am not sure whether this function has been removed too.
the message line showed :
FRM-40367: Invalid criteria in field <field_name> in example record.
It happens if the criteria contains # or : or &
Or is it done via another way?
Any help would be grateful.
Many thanks,
Imelda.

Index Usage from SQL query in Oracle Forms

Would using LIKE/OR in where clause (of an indexed column) will force the the query to NOT use INDEX. We have these where clause in Oracle Forms Records Group.
Below are two examples...
1. If we have a where clause with LIKE would that NOT use the index?
Example: ColumnName like :block.Column||%
2. How about having an OR clause?
Example: and (ColumnName = :block.column or :block.column is null)
Thanks

Hi
Answer 1: Where with like clause WOULD use the index.
In this example index on ColumnName
Answer 2: Write better where:
Example: and (:block.column is null or ColumnName = :block.column)
When :block column is null then statement after 'or' is not used. Index will not be used with RBO, i think.
The best way to be sure is to look at explain plan on the original query.

Getting Logged on User'Information in an Oracle-Form SSO Partner Application

Hi.
I could run Flight-of Fancy Application and capture user's information by calling the
"Parse_cookie " Procedure.(use the Scenario 2 - Access the Portal and then the FOF App)
and defined an Oracle-Form application as Partner application like FOF.
I want to have Logged on user'Information in the "Oracle-Form" . But the Fucntion owa_cookie.get dosen't work correctly.please let me know what can I do ?
Thanks in advanced.

Thanks in advanced. If you're writing your own partner application, then you are correct to get the user information from the output variables
from the parse_url_cookie procedure. You should then set the information you want to keep track of in the cookie, or combination
of cookie and persistent storage in the database. Take care of the security implications while doing this.
On subsequent calls to your application, the user info should be obtained from the cookie and the database, if you
are using a combination of the cookie and database storage to keep your info.
The owa_cookie.get routine is used to read the cookie, which is generated with owa_cookie.send.
These routines work fine, when invoked correctly.
If you are having trouble with them, you're probably not using the calls properly.
The following code provides an example of how to use the owa_cookie calls...
create or replace package testcookie
is
    procedure show (p_name IN VARCHAR2);
    procedure send
        p_name    IN VARCHAR2,
        p_value   IN VARCHAR2,
        p_path    IN VARCHAR2 default null,
        p_expires IN VARCHAR2 default null
end testcookie;
show error package testcookie
create or replace package body testcookie is
    procedure show (p_name IN VARCHAR2) is
        v_cookie owa_cookie.cookie;
    begin
        v_cookie := owa_cookie.get(upper(p_name));
        htp.htmlopen;
        htp.bodyopen;
        htp.print(v_cookie.vals(1));
        htp.bodyclose;
        htp.htmlclose;
    exception
        when others then
            htp.htmlopen;
            htp.bodyopen;
            htp.print('NO COOKIE FOUND.');
            htp.print(SQLERRM);
            htp.bodyclose;
            htp.htmlclose;
    end;
    procedure send
        p_name    IN VARCHAR2,
        p_value   IN VARCHAR2,
        p_path    IN VARCHAR2 default null,
        p_expires IN VARCHAR2 default null
    is
        v_cookie owa_cookie.cookie;
        l_agent varchar2(30);
        l_expires varchar2(30);
        l_path varchar2(100);
    begin
        if p_expires is null then
            l_expires := null;
        else
           l_expires := to_date(p_expires, 'MMDDYYYY');
        end if;
        if p_path = 'ALL' then
            l_path := '/';
        else
            l_path := null;
        end if;
        owa_util.mime_header('text/html', FALSE);
        l_agent := owa_util.get_owa_service_path;
        l_agent := substr(l_agent, 1, length(l_agent) - 1 ) ;
        owa_cookie.send(
            name    => upper(p_name),
            value   => p_value,
            expires => l_expires,
            path    => l_path
        owa_util.http_header_close;
        htp.htmlopen;
        htp.headopen;
        htp.headclose;
        htp.bodyopen;
        htp.print ('Cookie set.');
        htp.bodyclose;
        htp.htmlclose;
    end;
end testcookie;
