Forms :: Possible To Alter A Session Within Oracle Form
Sep 3, 2010
Is it possible to alter a session within Oracle forms as I get the following error when trying to compile the following block.
BEGIN
EXECUTE IMMEDIATE ( 'alter session set nls_date_format = 'DD-MON-YYYY''');
END;
Error: Encountered the symbol "IMMEDIATE" when expecting one of the following
The basic requirement is to validate a date field on the form against the current system date, but as the form is in format DD-MON-YYYY and the Database on M/D/YYYY I am struggling to compare dates successfully.

I'm issuing an alter session setting NLS_DATE_FORMAT in a C batch process right after the connection takes place. The format I specify is YYYYMMDDHH24MISS, this is the format used all over the process. In my development environment this works perfectly, but I've had problems in other environments.
CASE A development environment: The process works fine, $NLS_LANG and $NLS_DATE_FORMAT environment variables are not set.
CASE B Test envirnonment 1: The process failed.$NLS_LANG=American_America.WE8ISO8859P1 $NLS_DATE_FORMAT environment variable is not set.For some reason the $NLS_LANG variable seems to have more weight than the alter session command.. why? The process works fine after setting $NLS_DATE_FORMAT to the desired format.
CASE C Test envirnonment 2: The process failed. $NLS_LANG and $NLS_DATE_FORMAT environment variables are not set. Can't get it to work here. why?

how to change the default format of a number value using alter session statement?
I've a problem when I show a value like this "0.123456": the select statement returns ".123456". Is there any way to force a zero value before the character separator?

I was trying to execute below query inside a sql script which is called from a shell script on linux environment. EXECUTE IMMEDIATE 'alter session set events ''10176 trace name context forever'' ';
This thing works at our test environment. But giving error "SP2-0670: Internal number conversion failed" when tried on live(production) environment. What could be the reason? I found another way of writing such queries on net as follows, will it be useful? EXECUTE IMMEDIATE q'|alter session set events '10176 trace name context forever'|

I'm using Oracle SQL Developer and querying on date fields. I use this "alter session" statement to set my default date time format to get my datetime values. My question is, is there a way I can incorporate the following statement into my "select" query so that Crystal can read it? I use the statement below before my select statement to query datetime differences. Problem is, Crystal doesn't like the statement below.
Using TO_CHAR( ) and formatting my date fields that way doesn't work when I have to take the difference between date fields to the minute/second level. That's why I use the alter session command below, but I cannot seem to incorporate it with my select statement as a Crystal data source.
alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS'

We have a Data Source with min_pool_size (10) and max_pool_size (20). A Data Source is by default a connection pool. By starting a transaction we are retrieving a connection from the pool (i.e., opening it to retrieve data, perform queries, inserts and updates). Our application server is JBoss. An application workflow uses many transactions to build a product. The same connection is not used by the application for the entire workflow; but, it uses and returns them to the connection pool. We do not use Java syntax like "rs.close():"... this is performed by iBATIS.
On the Linux side when we execute a "ps" command (ps -elf|grep -i ora) we see all the Oracle processes. A further refinement of that command (ps -elf|grep -i local=no)shows a list of the "waiting" connections in the connection pool. The DB may be queried with the following syntax:
SELECT schemaname, sid, serial# FROM gv$session where schemaname = 'APP_USER' order by SID;
A list of connected sid and serial numbers is returned, identifying which connections are in use. From here we are able to force the connection to trace by executing the following:
exec dbms_monitor.session_trace_enable(249, 6595, TRUE, FALSE); ! 249 and 6595 being SID and Serial# from query above
There should be no need to execute the inverse, since the connection is returned to the pool when the transaction is committed or rolled back.
exec dbms_monitor.session_trace_disable(249, 6595);
We are trying to trace in order to use the Quest Benchmark Factory. Their instructions request the following syntax be applied to each session:
alter session set events '10046 trace name context forever, level 4';
and again, the inverse should not be necessary.
alter session set events '10046 trace name context off'
When it became too cumbersome to alter each session as it appeared, we issued an "alter system" to monitor (trace) everything. The trace files filled the disk, and four hours of testing was stopped two hours in. Doing a system level trace is probably not a good idea.
My first inclination was to create a post-logon trigger to set trace in the session; however, these connections, coming from an JBoss connection pool, do not logon each time, and I presume that they are not all the "same session".
We opened a support ticket with Quest last Friday and do not have an answer yet. This was the third ticket with them, the first to get Benchmark Factory installed (the original installer did not work). The second ticket was to setting up a shared directory on Linux with a folder on Windows, a setup configuration required by their tool. The third ticket to address this issue.
They needed to contact "the developers" to answer the last two questions. Their latest suggestion is to fix ticket two so we "won't need to trace" anything. How do I set trace in these connections?

I am trying use host command in Oracle forms. I get the process id as input from the user and on clicking ok the form should kill the session related to process id.
PS: Users will be entering only frmweb.exe process id which are inactive.
cmd := 'CMD /C taskkill /F /FI /pid 'process which is got as input' /IM frmweb.exe'; host(cmd)I also tried by writing the above command into a .bat file in application server.When trying to execute the bat file it din work. But when tryin to run the bat file by double clicking in Application server the session was killed.
On executing the above I am unable to kill the process. I would also like to know whether the host command was successful or not. Orakill and alter session are working but I don want to use it.

I created a new form for Oracle Apps, At first when I ran the form from the application all the fields backgrounds were black, so I changed the background in the property palette to white and foreground to black.
Now it shows fine but when I close this form and open another those fields are now blacked out. What should I do, I know the problem comes from the new form.

I need to fire the KEY-DUPREC trigger as I click on the key combination Shift+P therefore; I added the following line of code in the frmweb.res file.
80 : 1 : "Shift+P" : 64 : "Duplicate Record"
It worked iff no error was raised. So, if I have a raise form trigger failure in the KEY-DUPREC trigger, a capital P will appear in the text field that called the trigger.
