10GR2 - Cannot get wb_rt_api_exec to execute a Process Flow

Question

Hi,
In version 10.1.3, I was able to use the wb_rt_api_exec procedure to execute process flows within a stored procedure (and called by an Enterprise Manager job).
I have tried something similar in 10GR2, but when I run stored procedure, it says it has executed successfully, but the process flow has not run.
My Stored procedure code is like:-
CREATE OR REPLACE PROCEDURE PROC_TEST IS
ret NUMBER;
BEGIN
ret:= rep_owner.wb_rt_api_exec.run_task('PROCESS_LOCATION','PROCESS','WF_TEST','','',1,1);
END PROC_TEST;
I have noticed there is an extra parameter p_background at the end of the run_task function and was not sure if I am setting it correctly. The procedure compiles ok, but does not run the process flow.
Can anyone help please?
Thanks

Answer 1

To run workflow from SQLPLUS I used the following script:
set serveroutput on
variable exec_return_code number;
begin
-- Initialize Return Code
:exec_return_code := rep_ISM_DEV2.wb_rt_api_exec.RESULT_FAILURE;
-- Run Task
:exec_return_code := rep_ism_dev2.wb_rt_api_exec.run_task('OWF_LOCATION','PROCESS','ALL_MARTS_PF', ' ' );
end;
Prior to running this script I have
1.     grant execute on rep_owner.WB_RT_API_EXEC to rep_user;
2.     OWF_MGR is registered as Repository user.
It is possible that you will get an error: PE-02018: Oracle Workflow schema OWF_MGR on host XXX.XX.XX.XX cannot be accessed using service ORCL through port 1521. Please check the location details and try again.
To overcome this problem log in to OWB Control Center as the target User (Runtime user) and executed the PF package from there manually. You will get a message that OWF_MGR location was registered by other user and you will get asked to supply the OWF_MGR password. The manual execution should finish normally. After that I am able to run the PF from a command line without problems. It looks like running the PF from the control center stores the OWF_MGR login information somewhere (anybody knows where?) and you do not need to supply it any longer.
Hope it helps.
