About The Book

The Oracle E-Business Suite is like a machine that requires constant maintenance and fine-tuning. With  experience comes the knowledge of how to tweak the parts and use the tools to make it run properly. Even for the experienced administrator, Oracle Applications is complicated to administer—let’s be honest, at times it can be a real headache. Making this task even more difficult is the need to search through numerous MetaLink notes and references, Oracle’s online Electronic Technical Reference Manuals (eTRMs), and other published works for the how-to of daily tasks. As with most trades, there are hidden secrets that are uncovered only through experience or trial and error.

About The Book

Secrets of the ORACLE Database brings together a wealth of information on undocumented as well as incompletely documented features of the ORACLE database management system (DBMS). It has been my goal to combine many of the hidden features of the ORACLE database server into a single source. You will be hard-pressed to find the same density of material on advanced, undocumented topics in another book. Certain topics addressed may also be found in articles on the Internet, but I have striven to provide more background information and indepth examples than are usually available on the Internet. The book also contains a significant amount of original material, such as the inclusion of think time in resource profiles for performance diagnosis, an emergency procedure for the conversion of a RAC installation to a single instance installation, as well as the integration of Statspack, Active Workload Repository, and Active Session History with SQL trace.

This book focuses on database metadata (data about data) or annotation-based code recipes for JDBC API for use with Oracle and MySQL. The book provides complete and working solution for performing database metadata tasks using JDBC. You can cut and paste solutions from this book to build your own database metadata applications. All the solutions have been compiled and tested against two leading databases: MySQL and Oracle. This book is ideal for anyone who knows some Java (can read/write basic Java programs) and some JDBC (can read/write basic queries using JDBC and SQL) and wants to learn more about database and result set metadata. Each section of this book is a complete recipe (including the database setup, the solution, and the solutions for both MySQL and Oracle), so you can use the code directly in your projects (although sometimes you may need to cut and paste only the sections you need). You may adopt my solutions to other databases (such as Microsoft SQLServer, DB2, PostgreSQL) by just changing the database parameters (such as the driver, database URL, or database username/password).

Keeping Propagation Always Enabled In Oracle Streams

February 6, 2014, 10:59 pm

In this post I will describe to how to keep enabled Oracle Streams Propagation service for the target database by creating a Schedule Job and procedure.

The Propagation is service that transfers the new changes from the source database to target database, if this service get stopped then no data changes will apply to the target database. I already explained in my previous post to how to create Oracle Streams Replication.

1. First login into database with Streams admin credentials.

CONNECT [SOURCE_STREAM_ADMIN]

2. Then create the table to maintain the propagation log, so that you can view when the propagation service was stopped and when it get started again.

Create Table Propagation_Audit (
Propagation_name Varchar2(30)
,Source_queue_name Varchar2(30)
,Destination_queue_name Varchar2(30)
,Destination_dblink Varchar2(128)
,Status Varchar2(8)
,Error_message Varchar2(4000)
,Error_date Date
)
/

3. Then create a procedure to log the disable status and re-enabled it.

Create Or Replace PROCEDURE Ckprop_Enable
As
   Errnum   Number;
   Errmsg   Varchar2 (4000);

   CURSOR Prop_status
   Is
      Select Propagation_name, Destination_dblink, Status, Source_queue_name,
             Destination_queue_name, Error_message, Error_date
        From DBA_PROPAGATION
       Where Status != 'ENABLED';
BEGIN
   For Rec In Prop_status
   LOOP
      Insert Into Propagation_Audit
           Values (Rec.Propagation_name, Rec.Source_queue_name, Rec.Destination_queue_name,
                   Rec.Destination_dblink, Rec.Status, Rec.Error_message, Rec.Error_date);

      COMMIT;

      BEGIN
         Dbms_Aqadm.enable_Propagation_Schedule (Rec.Source_queue_name, Rec.Destination_dblink);
      EXCEPTION
         When Others
         Then
            Errnum := SQLCODE;
            Errmsg := SQLERRM;

            Insert Into Propagation_Audit
                 Values ('CKPROP_ENABLE', Rec.Source_queue_name, 're-enable propagation for',
                         Rec.Destination_dblink, 'ERROR', Errnum || ': ' || Errmsg, Sysdate);

            COMMIT;
      END;
   END LOOP;
EXCEPTION
   When Others
   Then
      Errnum := SQLCODE;
      Errmsg := SQLERRM;

      Insert Into Propagation_Audit
           Values ('CKPROP_ENABLE', 'Exception handler', Null, Null, 'ERROR',
                   Errnum || ': ' || Errmsg, Sysdate);

      COMMIT;
END Ckprop_Enable;
/

4. Then create a scheduled job to check at specified interval.

Exec DBMS_SCHEDULER.CREATE_JOB (
job_name => 'propagation_check', 
job_type => 'STORED_PROCEDURE', 
job_action => 'ckprop_enable', 
number_of_arguments => 0, 
start_date =>Sysdate, 
repeat_interval => 'FREQ=MINUTELY;INTERVAL=5', 
end_date => Null, 
enabled => TRUE, 
auto_drop=>FALSE, 
comments => 'EVERY 15 MIN');

Its done.

An example is given below to stop the execution of a particular DDL command in Oracle Streams. In this example you will learn how to ignore Drop Table command at the target schema in Oracle Streams.

1. Connect to the target database with the streams admin credentials.

conn STRMADMIN/STREAM@TARGET

2. Create a procedure to handle the drop table statement.

create or replace procedure
 IGNORE_DROP_TABLE (in_any IN SYS.ANYDATA
 )

 is
 lcr SYS.LCR$_DDL_RECORD;
 rc PLS_INTEGER;

 begin
 rc := in_any.GETOBJECT(lcr);

 if lcr.GET_COMMAND_TYPE != 'DROP TABLE'
 then
lcr.execute();
 end if;
 END;
 /

3. Alter the Apply process.

 begin
 dbms_apply_adm.alter_apply(
 apply_name => 'STREAMS_APPLY',
 ddl_handler => 'IGNORE_DROP_TABLE');
 end;
 /

Now all DDL statements except "Drop Table" will execute in the target database.

Queries Taking Too Much Time Due To Row and Table Locking In Oracle

You are trying to update particular rows in a table in Oracle and the statement taking too much time and after some time you get the error ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired.

After getting this error you identified the problem, to follow Oracle best practices for application development, use the NOWAIT clause and minimize the use of LOCK statements unless the application requires it. When a DML statement runs, the NOWAIT clause returns immediately if there is already a lock on the resource you require for the DML statement.

To avoid the wait during the UPDATE attempt, use the NOWAIT clause in a SELECT before the UPDATE statement in all sessions, as follows:

select * from employees e
where employee_id = 101
for update of salary nowait
;

If another session already has the row locked, you will receive this error message:

The following is the screen shot for this example: (you can also download the form from this link Job_History.fmb)


For the employee id field of upper block write the When-Validate-Item trigger code as below:

Begin
Select first_name||''||last_name into :ctrl.ename from hr.employees
  where employee_id = :ctrl.empid;
exception
when no_data_found then
   message('Employee id does not exists');

Cursor C_jobs
 is
 Select employee_id, start_date, end_date,
        job_id, department_id
        from hr.job_history
        where employee_id = :ctrl.empid;
Begin
go_block('job_history');
-- first clear the block if it contains any records
clear_block(no_validate);
-- move control to first record;

I have written many posts previously on Timers in Oracle Forms like how to change images randomly with timers and how to display a clock using timer, but in this post I am simply describing to how to create a timer, stop a timer, re-start a timer and deleting a timer.

The following is the screen shot for this example showing a progress bar based on a display item:


You can also download this form from the following link Timer.fmb

Create a display item with the following properties:

Name: Prgbar
Width: 5
Bevel: Plain
Background Color: blue

Write the following code for the "Create Timer" button:

When-Button-Pressed trigger
Declare
v_timer timer;
Begin
-- find timer first if already exists.
v_timer := find_timer('PrgBarTmr');
if id_null(v_timer) then
-- Creating timer for one second... one second = 1000 millisecond
v_timer := Create_Timer('PrgBarTmr', 1000, Repeat);
else
message('already exists.');
end if;

-- will handle this timer in form level when-timer-expired trigger
End;

Write the following code for the "Stop Timer" buton:

When-Button-Pressed trigger
Declare
v_timer timer;
Begin
-- find the timer first
v_timer := find_timer('PrgBarTmr');
if not id_null(v_timer) then
-- this will stop the timer after one millisecond
Set_Timer(v_timer, 1, No_Repeat);
end if;
-- will handle this timer in form level when-timer-expired trigger
End;

Write the following code for the "Re-Start Timer" buton:

When-Button-Pressed trigger
Declare
v_timer timer;
Begin
-- find the timer first
v_timer := find_timer('prgbartmr');
if not id_null(v_timer) then
-- this will re-start the timer after one second
Set_Timer(v_timer, 1000, Repeat);
else
v_timer := create_timer('prgbartmr',1000, Repeat);
end if;
-- will handle this timer in form level when-timer-expired trigger
End;

Write the following code for the "Delete Timer" buton:

When-Button-Pressed trigger
Declare
v_timer timer;
Begin
-- find the timer first
v_timer := find_timer('PrgBarTmr');
if not id_null(v_timer) then
-- this will delete the timer
Delete_Timer(v_timer);
end if;
End;

Then finally write the code for When-Timer-Expired trigger at form level to handle the timer and to do specific task:

When-Timer-Expired trigger
Declare
v_timer_name varchar2(30);
v_width number;
Begin
-- get the timer name first.. to know which timer has expired.. if multiple timer are running
  v_timer_name := get_application_property(timer_name);
  -- check if the same timer with capital letters
  if v_timer_name = 'PRGBARTMR' then
  v_width := get_item_property('blKtmr.prgbar', width);
  if v_width < 100 then
   v_width := v_width + 5;
  else
   v_width := 0;
  end if;
  set_item_property('blktmr.prgbar', width, v_width);
end if;

-- will handle this timer in form level when-timer-expired trigger
End;
