Usage

This section describes an example of implementation Progress bar Pro in an Oracle APEX application.

Example for basic PROCESS implementation

The initial state of a basic PROCESS progress bar in page designer is presented below.

Steps:

1. Add Process »My Process«

   

   Example of PL/SQL Code:

   declare
       l_processname varchar2(128 char) := 'PROCESS_01';
   begin
       UC_PROGRESSBAR_PKG.start_process(p_process_name => l_processname,
                                        p_maxval => 100);
       for i in 1..20
       loop
       -- Pause for 0.5 second.
         UC_PROGRESSBAR_PKG.set_status(p_process_name => l_processname,
                                       p_value => i*5,
                                       p_process_text => 'completed');
         sys.DBMS_SESSION.sleep(0.5);
       end loop;
   
       UC_PROGRESSBAR_PKG.stop_process(p_process_name => l_processname);
   end;

2. Add a Button to the region and create the dynamic action (event Click)

3. Create a True Action of type UC – Progress Bar Pro [Plug-In]

   

4. Under Attributes the following must be set:

   • Process / Job Name: PROCESS_01 (Name must be the same as in Process PL/SQL code and we also recommend  that the process and job name is always unique)

         l_processname varchar2(128 char) := 'PROCESS_01';

Example for basic JOB implementation

The initial state of a basic JOB progress bar in page designer is presented below.

Steps:

1. Add a Button to the region and create the dynamic action (event Click)

2. Create a True Action of type Execute server-side Code

   

   Example Code:

   if not UC_PROGRESSBAR_PKG.is_running(p_process_name => 'J_UC_PROGRESSBAR_SAMPLEJOB_01')
   then
       dbms_scheduler.set_job_argument_value(job_name => 'J_UC_PROGRESSBAR_SAMPLEJOB_01',
                                             argument_position => 1,
                                             argument_value => 'J_UC_PROGRESSBAR_SAMPLEJOB_01');
     DBMS_SCHEDULER.RUN_JOB(
       JOB_NAME            => 'J_UC_PROGRESSBAR_SAMPLEJOB_01',
       USE_CURRENT_SESSION => FALSE);
   end if;

3. Create a True Action of type UC – Progress Bar Pro [Plug-In]

   

4. Under Attributes the following must be set:

   1. Action : Show progress bar (JOB name)

   2. Process / Job Name : J_UC_PROGRESSBAR_SAMPLEJOB_01 (Name must be the same as in PL/SQL code and we also recommend  that the process and job name is always unique)
