Enable/Disable Concurrent program parameter based on Other Parameter

Based on a request, here is the details on how parameter can be enabled/disabled based another parameter value.
Below is the requirement
There are 2 valuesets parameter. If for parameter 1 user selects Yes then the other paramter should be enabled whereas if No is selected then the parameter should remain disabled. This can be achieved by using a hidden parameter as explained below.

Step1: Need 3 value sets for 3 parameter.
Value set1 = BOM_SRS_YES_NO (Oracle Defined)
Value Set2 = AMS_SRS_CHAR1 (Oracle Defined)
Value Set3 = SV_DEPENDENT_VS (User Defined)




Step2: Create Concurrent program as displayed in the screenshot below
Parameter1: Main Parameter

Parameter2: Hidden PArameter

Parameter3: Dependent Parameter

Step3: Assign concurrent program to a request group and test your program.

The PL/SQL Wrap Utility - Hide source code in Oracle

A company has a code(Package, Procedure, Function etc) with all the proprietary information and logic in it. If this information is leaked out in the market then the competitors can take advantage of it and this can affect the business. One of the way to deal with this is to hide the code from others.
This can be achieved using oracle's WRAP utility. The advantage of WRAP utility is that this converts the source code into some language that is not understood but the code can still be compiled like any other source code.
Using Wrap is very simple. In the bin directory of Oracle Home, the wrap utility is installed. The file name could be WRAP.exe or WRAP80.exe depending on the oracle version installed.
Syntax

 C:\orant\BIN>wrap.exe iname=[inputfilename] oname=[outputfilename] 


e.g.
 C:\orant\BIN>wrap.exe iname=wrap_test.sql oname=wrap_test.plb 


An example of using WRAP

Create a sample procedure wrap_test using following code

CREATE OR REPLACE PROCEDURE wrap_test
IS
BEGIN
dbms_output.put_line('Wrap test complete');
END;
/
then call the wrap utility using following
wrap.exe iname=wrap_test.sql oname=wrap_test.plb

Content of new file wrap_test.plb
CREATE OR REPLACE PROCEDURE wrap_test wrapped
a000000
b2
abcd

m7JK/iiyveeysx0GMCyuJOqygaVR2+EC8XcG0wJd5GisbnfxwzIu9tHqJB/2OabWTW+0

/

It is very clear from this that the new code is not readable and so is completely hidden from others.
Drop your procedure(if already created) and recreate using the the new file wrap_test.plb which can be compiled as any other package. Important point here is that the source code will be hidden and cannot be read.
Another important point to remember is that once wrapped, a code cannot be unwrapped.

Thanks please let me know your feedback.

The query will list SHIP TO and BILL TO Address for a customer.

Please do let me know if this queries are helping and I will post more of such queries.

Note: The query is not tested completely. If any problem found with the above query please let me know and I will try to fix them.

Create List of Values (LOV) in Discoverer

The Item classes in Discoverer are treated as List of Values (LOVs). A List of value can be created and referenced by several fields of the folder.
Following are the steps to create LOV in discoverer. In the example below I am creating LOV on US States.
1) Connect to Discoverer using Admin and select the business area where folder/LOV needs to be created.
2) Create a custom folder for US States using following query

select * from ar_lookups
where lookup_type like 'STATE'

3) Select the field for which Item class is to be created and right click on that to select New Item Class. Click next on the wizard and finally click finish button to complete creation of Item class. In our example, the LOV is created on the lookup code field.

4) Now if any parameter is created based on Lookup Code column then the List of value will be attached to it.
5) This LOV can also be referenced by another column. For example there is another folder which has column Bill to State. Select that column and right click to go to the properties. Click on Item Class and select the Item class created in step 3.

Splitting String using Oracle SQL 9i

Run following query to split values seperated by comma(,)

 SELECT TRIM( SUBSTR ( txt
, INSTR (txt, ',', 1, level ) + 1
, INSTR (txt, ',', 1, level+1) - INSTR (txt, ',', 1, level) -1
)
)
AS token
FROM ( SELECT ','||:in_string||',' AS txt FROM dual )
CONNECT BY level <= LENGTH(txt)-LENGTH(REPLACE(txt,',',''))-1


Example
-------
If value of in_string is entered as 1234,2,3,45,6,7,7,88,9,346

Output is
TOKEN
-----
1234
2
3
45
6
7

88
9
346

FAQ: Common Tracing Techniques for Oracle Apps

1) How to enable trace in the Oracle Application screens / forms?
Below is the navigation to enable trace for forms
Help Menu --> Diagnostics --> Trace(Select appropriate trace as needed)

Most commonly if debugging an error, you may select trace with binds.
When debugging a performance issue, you may consider using trace with binds and waits.

Remember to disable trace as this will keep generating the file.

2) How to enable trace for a concurrent program?
Refer to post Create Trace File for Concurrent Program

3) How to enable trace for a concurrent program INCLUDING bind variables and waits?
The above method can be used to generate a trace file, but this does not includes bind variables and wait times.
Download and review the script, bde_system_event_10046.sql, from Metalink Note 179848.1.
The above script is used to turn on the trace with binds and wait(Level 12).
Run Script and press enter when prompted.
Return to application and submit your concurrent program.
The moment status changes to running, switch to SQL*PLUS and press enter again to turn tracing off.
Important: Note that the tracing is set at global level and any program that runs during time when trace is kept on will be traced. Hence it is very important to immediately turn trace off after your programs status changes to running.

4) How to enable trace for all actions that occur for a user?
Use profile option Initialization SQL Statement - Custom
Set the value at user level

BEGIN FND_CTL.FND_SESS_CTL('','', '', 'TRUE','','ALTER SESSION SET TRACEFILE_IDENTIFIER='||''''||'4269824.999' ||''''||' EVENTS ='||''''||' 10046 TRACE NAME CONTEXT FOREVER, LEVEL 12 '||''''); END;

Various options with TKPROF

The post is in continuation to SQL Trace and TKPROF

Syntax of TKPROF

tkprof [filename1] [filename2] [WAITS] [SORT] [PRINT]
There are few more but these are more commonly used.

Argument Description
filename1 : The trace file name
filename2 : Filename to which TKPROF writes formatted output
WAITS : Flag to record summary for any wait events found in the trace file. Values are YES or NO
SORTS : Sorts traced SQL statements in descending order of specified sort option before listing them into the output file
PRSCNT Number of times parsed.
PRSCPU CPU time spent parsing.
PRSELA Elapsed time spent parsing.
PRSDSK Number of physical reads from disk during parse.
PRSQRY Number of consistent mode block reads during parse.
PRSCU Number of current mode block reads during parse.
PRSMIS Number of library cache misses during parse.
EXECNT Number of executes.
EXECPU CPU time spent executing.
EXEELA Elapsed time spent executing.
EXEDSK Number of physical reads from disk during execute.
EXEDSK Number of physical reads from disk during execute.
EXEQRY Number of consistent mode block reads during execute.
EXECU Number of current mode block reads during execute.
EXEROW Number of rows processed during execute.
EXEMIS Number of library cache misses during execute.
FCHCNT Number of fetches.
FCHCPU CPU time spent fetching.
FCHELA Elapsed time spent fetching.
FCHDSK Number of physical reads from disk during fetch.
FCHQRY Number of consistent mode block reads during fetch.
FCHCU Number of current mode block reads during fetch.
FCHROW Number of rows fetched.

PRINT : Number of SQL statements to be displayed

Example 1
If you are processing a large trace file using a combination of SORT parameters and the PRINT parameter, then you can produce a TKPROF output file containing only the highest resource-intensive statements. For example, the following statement prints the 10 statements in the trace file that have generated the most physical I/O:

tkprof abcd53269.trc abcd53269.txt SORT = (PRSDSK, EXEDSK, FCHDSK) PRINT = 10


Example 2
Print the SQL Query taking maximum CPU Usage
tkprof abcd53269.trc abcd53269.txt SORT = (EXECPU,FCHCPU) PRINT = 1
