Oracle Open Interface

What is Oracle open interfaces?

Open interfaces used to integrate Oracle Applications with the non-oracle systems.
such as
1. Import data from your custom applications or legacy systems.
2. Migrate the old custom application data to the Oracle applications.
3. Import data from the banks, partners, suppliers, customers etc.


What is conversion?

Conversion is a one time Interface to migrate data from legacy application to the Oracle


Inbound Interface
The Interface which transforms and loads the data into the Oracle Applications system is called inbound interface.


Outbound Interface
The Interface which extracts the data from the oracle Application system for the purpose of loading into the external system is called outbound interface.


Common approach to interface is
  1. Data would be extracted from the source machine and loaded into the custom table (stagging table) in Oracle apps database. Depending upon the complexity of the data Stagging table can be avoided.
  2. The extracted data is then transformed into a form which oracle can recognize and pushed into interface tables.
  3. Final step is load the data from interface table to base table of Oracle applications.
This whole process is called extract load and transformation (ETL).


Oracle provides Interface tables for data intensive applications like Invoice, receipts, journals etc and PL/SQL APIs for master data interfaces like people, items, suppliers etc.


Traditional approach used sql Loader to load the data and pl/sql program to validate and extract data.
Modern approach uses BPEL, ESB for online data interfaces and Oracle Data Integrator for data intensive batch processing.


Common Interface technologies
1. XML Gateway
2. SQL*Loader
3. DB Link
4. Java Concurrent Program
5. BPEL or ESB
6. Oracle Data Integrator or ODI
7. PL/SQL package for reading file or XML data
8. Oracle Advanced Queuing


Some Useful Links

1. Oracle Integration Repository - List of Oracle open interfaces
2. Technical reference Manual - Column level details of Interface tables, base tables and APIs

Call pl/sql in ADF

How to Call pl/sql from ADF?


You can use the following code to call a pl/sql block from the ADF bc Application module.


public void executePlsqlProcedure(){

CallableStatement updateStmt = null;
try {
// Put your PL/SQL block in a String variable.
String Stmt = "begin delete test_table where header_id = :1; "+
" :2 = xxx_pkg.yyy_function(); end;";
OADBTransaction txn = getDBTransaction();

// Pass the PL/SQL block to the callable Statement
updateStmt = txn.createCallableStatement(Stmt, 1);


// Set all the bind variables before calling the execute command
updateStmt.setInt(1, headerIdToDelete);

// And register the output parameter types
updateStmt.registerOutParameter(2, Types.DOUBLE);
updateStmt.executeUpdate();

// After execute you can get the value of pl/sql block output
Number amount = new Number(updateStmt.getDouble(2));
updateStmt.close();

// Commit the transaction in the database
txn.commit();


} catch(SQLException sqle) {
updateStmt.close();
}

}



And you can call the above Application Modules method from managed bean using following code.

FacesContext facesContext = FacesContext.getCurrentInstance();
ExpressionFactory exp = facesContext.getApplication().getExpressionFactory();
DCBindingContainer bindingContainer = (DCBindingContainer)exp.createValueExpression(facesContext.getELContext(),"#{bindings}",DCBindingContainer.class).getValue(facesContext.getELContext());
DCIteratorBinding itr = bindingContainer.findIteratorBinding("Dept1Iterator");
DemoAppAMImpl svc = (DemoAppAMImpl)itr.getDataControl().getApplicationModule();


Or you can call this method by exposing into client interface.

Logging in Apps

How to do logging in the OAF controller?

You can do logging in OAF page using following statement
pageContext.writeDiagnostics(this,"building is :"+s_building,OAFwkConstants.STATEMENT);

Syntax:
void writeDiagnostics(Object module,
String messageText,
int logLevel)

Writes an entry to the diagnostics log according to a specific log level.

Parameters:
module - current module, usually the "this" pointer
messageText - message to be included in the log. Limit 4000 characters.
logLevel - category or type of log message. Valid values are are from OAFwkConstants. (UNEXPECTED, ERROR, EXCEPTION, EVENT, PROCEDURE, STATEMENT, PERFORMANCE)


How to do logging in the bc4j objects?

The pagecontext won't be available for Application module, View Object Impl and Entity object Impl. So in this case, you can use OADBTransactionImpl.writeDiagnostics to log your messages.

oracle.apps.fnd.framework.server.OADBTransactionImpl

Syntax:
public void writeDiagnostics(Object module,
String messageText,
int logLevel)

Writes an entry to the diagnostics log according to a specific log level.

Parameters:
module - current module, usually the "this" pointer
messageText - message to be included in the log. Limit 4000 characters.
logLevel - category or type of log message. Valid values are are from OAFwkConstants. (UNEXPECTED, ERROR, EXCEPTION, EVENT, PROCEDURE, STATEMENT, PERFORMANCE)


Eg:
if (OADBTranasctionImpl.isLoggingEnabled(OAFwkConstants.PROCEDURE)) {
OADBTransactionImpl.writeDiagnostics(this, "your message", AFwkConstants.PROCEDURE);
}


How to see the log?

You can see the output in the OAF Screen itself.
1. Select Diagnostics button from any page
2. In the Diagnostics page select Show Log on Screen option.

Now you will be able to see the application log appened to the bottom of the page.



How to debug pl/sql program?

The standard way to debug the plsql code is using fnd_log package.
set the following profile options to enable log.

FND: Debug Log Module = '%'
Enables log for all modules

FND: Debug Log Enabled = 'Yes'
Enables the logging

FND: Debug Log Level = 1
This will log all the statement level log messages.


You can use the following procedure to log the messages in pl/sql, forms or reports.

--Get the log enabled profile option
g_fnd_debug CONSTANT VARCHAR2(1) := NVL(FND_PROFILE.VALUE('AFLOG_ENABLED'),'N');
--Check if the log is enabled
IF (g_fnd_debug = 'Y') THEN
--Check if the log level is less than procedure level
IF (FND_LOG.G_CURRENT_RUNTIME_LEVEL <= FND_LOG.LEVEL_PROCEDURE) THEN
--Log the message
FND_LOG.string(FND_LOG.LEVEL_PROCEDURE, g_module_prefix || l_api_name ||'.invoked', 'Log text');
END IF;
END IF;


How to see the pl/sql debug log?

All the FND_LOG.string messages would be logged in the fnd_log_messages table ordered by log_sequence column.

1. Note the sequence number before running the procedure
select max(log_sequence) from fnd_log_messages;

2. Run your pl/sql program

3. Now run the following query to see the log messages.
select count(*) from fnd_log_messages where log_sequence BETWEEN 1925713 and 1929506;

Debug bc4j objects or ADF BC Objects

How to debug the VO, LOV, poplist queries?

You can see the executed queries and its bind values in the jdeveloper console or messages window.
By default, this option is not available in jdeveloper.

To enable the debug console option in 11g and 12c

I was just going through my previous posts and found the this option still works on Jdeveloper 11g and 12c. So you could use the debug option on the ADF BC - Model project and it will log all the queries on the jDeveloper console during execution.

Just follow same set of instructions as given for 10g jdeveloper.


To enable the debug console option in 10g

1. Right click on project and select project properties

2. Select Run/Debug

3. Ensure Default in selected in Run configurations

4. Select Edit button.

5. You can see the Launch Settings window.

6. Add the following parameter in the java options
-Djbo.debugoutput=console

7. Select OK

8. Rebuild the project and run again to see the debug information in jdeveloper log window







To enable the debug console option in Jdev 9i
1. Right click on project and select project properties

2. Navigate Configurations -> Development -> runner

3. Add the following parameter in the java options
-Djbo.debugoutput=console

4. Select OK

5. Rebuild the project and run again to see the debug information in jdeveloper log window







This option would be very helpful in finding out what going on in the bc4j objects. Including LOV queries, poplist queries, VOs etc. Whenever the query is executed through the AM or procedure is called, the bind variable values and executed sql will be displayed in the jdeveloper message window.

System.out.println

System.out.println


This is the most commonly asked question in web applications development in jdeveloper including OA Framework, ADF, ejb, web services etc.


Can I leave System.out.println or System.err.println in the production code?

System.out.println comes handy when debugging the application because you can see the messages pretty much easily in the jdeveloper console. And it takes relatively less time than the debugging option in Jdeveloper. So even experienced developers use it for debugging. You may think, "Anyway this doesnot any affect in the production system". But actually System.out.println statements will have serious performance issue in the production system if you fail to remove them in the final code.

The reason is that the application server will have only one output stream and one error stream in the JVM. Hence multiple threads calling the System.out.println() have to be synchronized.

Considering the production system with thousands of users, back end programs, webservices, scheduled process running parralley in the machine. Calling system.out.println() will potentially block the performance of whole system.

Also the application server doesn't redirect the std out to a file, and is lost.



Hence always remove the System.out.println() /System.err.println() from the production code.

  • What is sql trace?
  • How to take sql trace for a session?
  • How to do sql trace for a Form?
  • How to do sql trace for a Report?
  • How to do sql trace for a OAF Page?


What is sql trace?
  • SQL Trace is a diagnostic tool for sql runtime and it gives a raw dump of SQL queries executed in the session and this dump can be read using tkprof command.
  • Statements are displayed in the order they are processed.
  • Every statement excuted will be displayed with statistics and optimizer routing.
  • You can see what values are being bound at runtime.
  • If you are getting a runtime error like ORA-942 or ORA-904, you can find out which statement is causing it.

How to take sql trace for a session?

Enabling trace for the current session
  • alter session set sql_trace=true;
  • alter session set events ‘10046 trace name context forever, level <x>’;
  • dbms_session.set_sql_trace(true);
  • dbms_support.start_trace(waits=>true,binds=>true);

Enabling trace for a different session
  • dbms_system.set_sql_trace_in_session (SID,SERIAL#,TRUE);
  • DBMS_SUPPORT.START_TRACE_IN_SESSION( SID , SERIAL#, waits=>TRUE, binds=>TRUE )

How to do sql trace for a Form?

  • Help -> Diagnostics -> Trace and then Choose the trace level.
  • Note the path of the trace file displayed in the Dialog box
  • Do the transcation that is causing the performance problme
  • Help -> Diagnostics -> No Trace, to disable the trace
  • Trace file XXX.trc is returned in the path displayed in the dialog box.
From Trace 1


Copy the path displayed in the alert window

Form Trace 2


How to do sql trace for a Report?

Add the following statement in the before report trigger
  • 1. SRW.DO_SQL ('ALTER SESSION SET SQL_TRACE=TRUE');
  • 2. Upload the report in Oracle Apps
  • 3. Goto Application Developer Resposibility
  • Select Concurrent -> Program
  • 4. Query for the Concurrent Program that executes the report
  • 5. Select "Enable Trace" checkbox and save the record
Reports Trace
  • 6. Now run the report to get the trace file. (don't forget to disable the trace after running the report)



How to do sql trace for a OAF Page?

  • Set profile FND : Diagnostics to Yes at user level
  • Login to Self Service as the above user
  • Click on Diagnostics icon at the top of page
oaf trace

  • Select ‘Set Trace Level’ and click Go
  • It Displays following options
    • Disable Trace
    • Trace (regular)

    • Trace with binds and waits
  • Select the desired trace level and click Save
oaf trace2
  • Perform the activity that you want to trace
  • Disable the Trace using Diagnostics Page.
  • Exit application
To determine where the raw trace file is located.
From SQLPlus execute following query:

SELECT value FROM v$parameter WHERE name = 'user_dump_dest'



How do I read the trace file or .trc file?
  • tkprof <tracefile> <outputfile> explain=username/password sort='(sorting options)'
  • Eg: tkprof POSTDI9837.trc output.prf explain=apps/apps sort=‘(prsela, exeela, fchela)’
