Process Flow Scheduling

Hi All,
I have a Master Flow which has 5 process flows in it.
MF = PF1--->PF2--->PF3--->PF4--->PF5
This MF is shceduled to run every 30mins.(using the OWB10.2.0.4 inbuilt scheduler)
I have two questions....
1) MF first intance of MF started at 1200HRS ..... PF1,PF2 processes of MF flows gets completed ,but it hangs up at PF3 for more that 30min....
since MF frequency is 30min.....second intance of MF will be triggered at 1230HRS before MF first instance completes. now how can we revert back the changes of PF1 and PF2 processes happened during the first instance of MF.
2) hoc can we restrict second instance of MF to start only after the completion of first instance of MF if it takes more than 30mins
Hope my questions are clear.
Thanks

1. I dont think you can since every PF is in its own session and you dont have control over it once it ends. What you can do is create procedures and use them as control service for your PF execution so when your master PF starts again first two processes that have ended dont get started again.
2. Again, procedures to control your execution. This can be done using OWF views. Checking OWF views you can see that first instance is still running and using that you can make sure that second instance does not start until the first one ends.

Start OWB Process Flow Schedule Job in Workflow Manager

I am trying to get the Oracle Workflow Schedule to execute my Oracle Warehouse Builder (OWB) Process Flow. Please note that execute Process Flow from the OWB deployment manager works fine. I did the following but nothing being executed:
Info:
OWB: 10g
Oracle DB: 10g
Oracle Workflow: 2.6.3
OracelAS: NONE
1. From the Oracle Workflow Manager browser, click the Background Engines->Submit New
2. Insert the following parameter:
Work Item Type: LD_STG
Run Date and Time: 10/18/2004 17:40:00
Run Every: 0 days, 00 hours, 01 minutes, 00 seconds
3. Click ok and system showed "Successfully submitted Background Engine with job number 107"
However, after the specificied schedule time, nothing happened. No error shown in the Work Item.
Any help are greatly appreciated. Thanks.

Linking Location to Process Flow & Schedule OMB Script in OEM.

Hi All,
Oracle 9i Warehouse Builder Client: 9.2.0.4.0
Oracle 9i Warehouse Builder Repository: 9.2.0.2.0
I created a process flow in OWB proj1 & selected loc1 as deployment location from the drop down help.
Is it possible to link a different location let us consider Loc2 from different OWB project prj2?
Can OMB PLUS Script invoke OWB Mapping or OWB Process Flow? Also can the OMB Plus Scrpit be scheduled in OEM?
Can someone please let me know ?
Thanks in Advance.
Regards,
Vidyanand

Hi Vidyanand,
Lots of questions... but I'm not sure what you mean with linking Loc2 from Prj2. Can you elaborate?
Easiest to execute mappings is SQL Plus or EM. You can use the SQL_EXEC_TEMPLATE to do this, take a look at the documentation in execution of mappings...

OWB Process Flow stuck

Hi Gurus,
I'm new to OWB, I hope to get some help from you!
I'm supporting a ETL system based on OWB. We have daily process flows scheduled to run without any issue, however, these couple of days the ETL process can not complete. It's always stuck at certain step. We kill the process, and re-run the process, but still can not solve the problem.
Have anyone of you encountered such a situation? What need to check?
Thanks!

You might want to check to see if you have anything "parallel" running
We recently had an issue with one of our mappings where one day it decided to just stop working and "freeze"
Our DBA found that we had a Oracle hint for "Parallel" in the code and removed it. After that the mapping ran fine.
Best of luck

Help with scheduling Process Flows in Workflow in 10gR2

Dear All
I am after some help with the scheduling of process flows (PF) in Workflow in OWB 10gR2. I am trying to set up some PF’s to handle the refresh of some staging tables from various source systems. I have created a separate Process Flow Module for each source systems, mainly just to keep them separate and organised. I have a number of mappings which all run fine if execute manually or linked directly to a schedule/job. The problem I am encountering is when I try to run process flows from schedules. I have created process flows ok and have run them manually and they complete fine so I know that the content of the PF is ok. After linking and deploying the jobs I can never get all the process flows to run from the various schedules. What appears to happen is that the first PF works ok and any other PF that are within the same Process Flow Module/packages also runs ok even if its running off as different schedules. However PF’s under the other Process Flow Module fail with the following error
CC_DAILY_0400
Description :
Runtime User : OWBRT_USER
Started : 2006-08-31 04:00:00.0

ORA-06512: at "OWF_MGR.WF_ENGINE", line 3920
ORA-06512: at line 1
Following this error the PF will not even run manually! If I then stop the schedule and either drop or replace this failed PF thus redeploying, the PF then runs fine manually and if the restart the schedule it runs ok the next evening. My problem is that this then appears to impact on the other PF’s which all though have not been touched and ran ok the previous evening they then fail the following evening with the same error
WS_DAILY_2400

ORA-06512: at line 1
ORA-20002: 3114: Activity is not a process.
I basically can not get both sets to run even though they are on separate modules and separate schedules.Has anyone any idea as to what could be wrong or if I am setting something up in a strange way which would cause these symptoms.
All help or advice greatly appreciated

To open a BPC excel input schedule through a Business Process Flow

Hi,
I have a Business Process Flow that has to open an excel input schedule.
In the define actions tab of a Process step, I have chosen the BPC for excel interface and open template option.
I browsed the necessary template to be opened.I have also provided the required inputs for member selection.
Now when I open the Business Process Flow and Select this Process step, it opens only the BPC for excel interface and not the excel input schedule template.
Can anyone expalin the reason that caused this problem and also a solution to fix this issue ?
PS :I am trying to open this Business Process Flow using BPC Web and my BPC for excel is not open yet.
Thanks in Advance

Hello Aparna,
Please select Application name in BPF.
Please check for Application name in which you are opening the template.
Thanks,

Scheduling process flows and mappings

Hello
I have created many process flows. Now i want to schedule it. I know i can use OEM, but i need to log in as DBA. i also know that you can use owb scheduler module to schedule a process flow. but i want to schedule it using sql plus. i found a link on scheduling process flow in sql plus for older versions of OWB. Can we use the same script for OWB 10.2? here is the link - http://www.dba-oracle.com/oracle_news/2005_7_7_Scheduling_an_OWB.htm
Please let me know how to schedule a process flow in OWB 10.2 in sql plus. It would be great if you could post the sql script required to schedule OWB 10.2 process flows.
Thank You

Hi,
the web server named by the link is down, so a general answer.
You can use the scripts sqlplus_exec_template.sql and oem_exec_template.sql from the directory <OWBHOME>/owb/rtp/sql and schedule it with cron or at or scheduler or ...

Scheduled process flow fails, run directly works ok

I've got a hard time with a process flow tthat needs to be scheduled.
When I start the process flow with wb_rt_api_exec it rus ok,
when I schedule the job calling wb_rt_api_exec in the Oracle Job scheduler it fails the moment it starts. The error message tells me I've got invalid user credentials, I cannot acces the wokflow location with the supplied userid and password.
It's the same user to schedule the job as the one that starts wb_rt_api_exec directly.
What can be rwrong?

Hi,
I have not used oracle job scheduler but just a taught....If ur id is able to access the package to execute the processflow that does not mean that the same id has the rights to do such actions thru a oracle job scheduler right?hope this leads to something...Do let me know any details reagrding the same....

Scheduling Mappings and Process Flows

Can you please tell me how to schedule mappings and process flows in a little detail, if any one has done that. I think OEM can be used for this but dont have any clear cut idea of doing it. Can the mappings/process flows be scheduled without using OEM console ?
Waiting for you suggestions.

Hi
You can schedule your mapping and process flows with OEM or database job.
You will find script templates in the OWB HOME/owb/rtp/sql directory
and you can scheldule them.
If you want to do it in OEM use the oem_exec_template.sql file createing an OEM job. Read the OWB documentation about it. If you have any question about it ask it, I have done this procedure many times.

Oracle 10G Database Control and Scheduling OWB Process Flow

Does anyone know how to go about scheduling an OWB Process Flow from
Oracle 10G Data Base Control. I knew how to do this with Oracle Enterprise Manager 9.2 but we recently upgraded to Oracle Db 10G and the interface has changed significantly.
Now the interface seems to require a PL/SQL stored procedure to be executed.
Is there a template procedure that is installed with 10G Data Base Control as there was for 9.2 i.e. oem_exec_template.sql?
Thanks! Deadline approaching fast...
Marion

I've used the oem_exec_template.sql successfully with OWB 10.1 and Oracle 10G Database Control, with a little trial and error at first.
I'm assuming that your job execution environment is set up correctly, ie. that you can properly execute jobs via the host agent.
1. Log on to Database Control as SYSTEM, select Jobs from the links at the bottom of the page
2. In the Results section, Create Job, select "SQL Script" and press Go
3. In the General section, enter Job Name, and as SQL Script enter e.g.:
@/u01/app/oracle/owb_oracle_home/owb/rtp/sql/oem_exec_template.sql owb_runtime WF_LOC PROCESS MY_PROCESS , ,
4. In the Databases section, add your target database
5. In the Credentials section, I select "Override Preferred Credentials" and use the agent account (oracle on my Linux system) and db user owb_access (OWB Runtime Access user)
6. Review Schedule tab and submit
Comments on step 3:
- the oem_exec_template.sql script must be installed according to the path specified in step 3, on the database host where the OWB Runtime Repository is located
- owb_runtime is the owner of my OWB Runtime Repository
- WF_LOC is the name of my Workflow Location as seen in OWB Deployment Manager
- MY_PROCESS is the name of a deployed Workflow Process
- the commas indicate that I don't supply any system or custom parameters.
- step 3 is actually a shell command line that is interpreted by eg. /bin/sh on Unix or cmd on Windows, and must obey proper quoting rules. On windows, I had to specify the empty commas as "\," (including dblquotes)

Scheduling Process flows

I have created process flow and created and schedule and attached it to the process flow thru configure and refferred calander and depoyed the process flow again. But the flow doesnt start.
Is there anything else to do. I read in form that some _job appears in Control center. I dont find in my control center.
Can anyone explain me any other steps which are required to run PF based on schedue.
Thanks..

Hi Tom
You will find pfname_JOB in the control center. if you expand the location under which you created your Schedule, you will see a scheduled jobs tree expand that and then you will find your schduled job( pfname_ JOB) which requires deployment to start running.
Hope this helps

Scheduling the Process Flows in Oracle Warehouse Builder

Hi,
Can you please let me know how to schedule the process flows.I mean to make the process flow to run on a daily, weekly basis etc.Where exactly we need to schedule the process flows.
It would be great if you can help me out.

Scheduling Process flows in scheduling tool Control M

Hi,
We need to schedule 3 to 4 process flows through the general scheduling tool "Control M". So how do we do this? I mean where should we login to run the OWB jobs (Process Flows) through Control M.
Any help will be appreciated.
Thanks,
Harsha

Create a shell script that will take in the required parameters you need (i.e.connection User/pwd@SID and OWB mapping inputs if required), which call sqlplus with a procedure that will run your workflow.
My current client migrates all OWB incl Worflows created through OWB by the means of export. This is why the prefix of the workflow activity will differ from an environment from another.
Here is a procedure that will launch the OWF and wait for the workflow to be completed before it exits and return control to CONTROL-M.

Process Flow errors in OEM Scheduler

Hi
I'm using OWB 10.1.03. I've created 2 process flows that load data from different sources. I have also set up a job schedule on Oracle Enterprise Manager (OEM) that runs a stored procedure. This procedure comprises two steps:
(1) Start a loop and check for a table flag. If flag set then Run Process Flow 1 (using
ret:= wh_runtime.wb_rt_api_exec.run_task('TARGET_LOC','PROCESS','WF_NAME','','',1)). Else keep looping until flag is set.
Then immediately after Process Flow has run,
(2) Start a loop and check for a different table flag. If flag set then Run Process Flow 2. Else keep looping until flag is set.
If there has been an error in Process Flow 1, the mapping completes with error and an email notification is sent. However, according to the stored procedure, Process Flow 1 has completed and it therefore moves onto Process Flow 2.
Is there a way of identifying if a Process Flow has completed with an error or warning, and therefore preventing the procedure moving onto step 2?
Thanks
GB

Hi
I managed to solve this by using part of the oem_exec_template.sql script within my stored procedure. I used l_audit_result to check the status of the workflow run and raised an exception if it was not a success.
