Scheduling in BPEL

Hi all!
All you know that BPEL can do next thing:
When we have a consistency of jobs (tasks, etc.) to do, usually it performed by directed acyclic graph (DAG). And some jobs we can execute parallel.
Also we have servers to execute jobs on it.
So, the question is: how BPEL constructs parallel schedule to optimize execution of jobs.
I mean the policy of assignation jobs to servers.
Any information - greets!
Thanks for attention
PS: Sorry for my English ;-)

BPEL is capable of parallel processing - for externalised services too (so you can deploy these one on a different server too) - or in a different BPEL domain (on the same server)..

Scheduling a BPEL Process

I am currently working on 10.1.3.4 on oracle application server. We have a need to schedule a BPEL process. This BPEL process is based on an AQ.
I know that there are other ways to schedule a BPEL process like using DBMS_SCHEDULER or writing some java code. Client does not like DBMS_SCHEDULER because it is database centric, and we don't have enough java expertise for coding at this time. What I was thinking that once this process is kicked off, I can put a wait for 5 minutes at the end of the process (Because this process is scheduled every 5 minutes), and then populate the AQ. Hence the current process will finish and the next one will be submitted. Hence it won't be a long running process.
My question is, will the WAIT cause a hit on the dehydration database? Also, is it a good way of doing things? We have a clustered environment and hence we cannot use the heartBeatInterval option in bpel.xml. I have heard that it does not work well with clustered environments.
Thanks
Asif

This sounds like a good approach for your case. Wait is usually discouraged when talking about scheduling because in those solutions, one tends to put wait in a while loop. Your case is free from such a flow, so this should work fine.

Scheduling a BPEL/ESB process

Hi,
We have a requirement to invoke a BPEL/ESB process (Reading from DB) at a particular time every day. I got the following options from Clemens Blog:
1. RDBMS Scheduler
2. Quartz
Kindly let me know which will be a better option, provided we need to trigger the BPEL/ESB process every day.
Any help will be appreciated as this is very urgent ...
Regards,
AP

You could make a list of pro and cons of the two solutions. It depends per project how this is implemented. From SOA point of view you could chose Quartz, but I also see customers using RDBMS scheduler while the DBA is more confident with this. I also see customers using the O/S scheduler like the 'crontab' in unix or the Windows equivalent.
It's hard to give you an advice, while I do not know the business requirements of the customer.

BPEL Scheduling in SOA Suite 11g

Hi,
I am new to Oracle SOA. I have come across of multiple ways of scheduling in BPEL (Using Servelts with Quartz, DBMS_JOB, Enterprise Scheduler, Wiat activity etc). Can any one suggest best approach to handle various scenarios in scheduling. What is the industry standard way of doing it? How should a scheduler handle the any erros during the BPEL executions?
As I know most of the cases, we are using BPEL exposed WSDL call for it's execution. But what is best practices to handle any errors during remote BPEL execution? Also can we get return paramaters to the scheduler from BPEL?
Thanks in advance.
Vic

Hi-
You can refer to the below link.

I have not personally tried but I think it should work.
PLease let us know how it goes.

ActivationAgent in bpel.xml and Quartz Scheduler

Hi,
i have added to bpel.xml to schedule my BPEL process.
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent"
partnerLink="FileFtpInboundPL" heartBeatInterval="10">
<property name="schedulerCallout">DefaultSchedulerCalloutImpl</property>
<property name="endpointScheduleOn">0 1 * * * ?</property>
<property name="endpointScheduleOff">0 2 * * * ?</property>
</activationAgent>
Can anybody tell me like
what is role of quartz scheduler in this case?
Is this above code related to quartz scheduler?
what is the BPM concept befing this scheduling property?
Thanks inadvance. It would be great help.

Hi,
Thank you for the reply.
Yes,bpel.xml is replaced by composite.xml but i was talking about sceduling the BPEL processes through bpml.xml files.
The example of which is given in following URL but is related to 10.x version and not 11G:

Schedule BPEL with polling frequency

Hi All -
I have a BPEL process which receives the file from file adapter and has polling frequency of 5 minutes.
But my process starts after 12.00 midnight. so I want to schedule the BPEL process after 11.30PM to 1.00AM and in between only it should poll.
Can it is possible? I just want to avoid polling all the 24hrs.
I am usning SOA 10.1.3.4.0. Can I use the below in this version, where I have to use te below, if it is correct?
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent"
partnerLink="FileFtpInboundPL" heartBeatInterval="10">
<property name="schedulerCallout">DefaultSchedulerCalloutImpl</property>
<property name="endpointScheduleOn">*0 6 1 ? * **</property>
<property name="endpointScheduleOff">*0 8 1 ? * **</property>
</activationAgent>
</activationAgents>
Regards,
Sreejit

Hi James,
Let me explain my process:
1. First process:
I have BPEL process which starts with recieve activity on database adapter. Database adapter has a polling on database table inserts or updates.
So whenever there are inserts and updates this BPEL process get starts. My business process say the table insert and update is going to happen in between 23:00 PM and 01:00AM. So I want to know how BPEL do polling? When I say database polling it must be looking for 24X7, and when i t gets the file it picks, so is there any way I can say the BPEL to do polling only withing the time frame.
So what ever solution we were discussed of activation agent till now in mail thread applicable on this or not?
2. Second Process.
I have asynchronus BPEL process which starts with wsdl client getting some input as payload, and I want to start this process at 23:00PM, is it possible with activation agent. The client partner link is not an adapter.
Regards,
Sreejit

Scheduling BPEL Process in 11g using native SOA Suite functionatliy

I have spent a significant amount of time reviewing documentation and the forums and have been unable to find a definitive answer on the ability to schedule a BPEL process in SOA Suite 11g.
A similar question was asked here with no response:
BPEL(SOA11G) and Quartz
In SOA Suite 10.1.3.x it is discussed frequently:
http://www.oracle.com/technology/tech/soa/soa-suite-best-practices/soa_best_practices_1013x_drop1.pdf
Re: BPEL Adapters & Scheduling
It appeared to be an actual feature in one of the technology previews:
http://biemond.blogspot.com/2008/01/scheduling-processes-in-soa-suite-11g.html
Can anyone provide an definitive answer on whether a BPEL process can be scheduled using functionality native to SOA Suite 11g. I understand there are external workarounds such as calling BPEL process from DBMS_JOB, using external scheduling framework etc. I am interested in solutions which are native to the SOA Suite itself if there is such a solution.
If there is no definitive answer I will open a support case and post the results here for the benefit of the group.

Is it possible to trigger a bpel process from a database object.

Hi,
We want to schedule a bpel process to run daily .So we want to trigger it from a database job.
Is it possible to call a bpel process from database..?
Or
Is there any way to schedule a bpel process from bpel server it self.
Thank you
Gayaz

If you know about DBMS_JOBs then I would say the easiest way to invoke a BPEL process is via the AQ adapter. You just need to populate an AQ and a way you go. The good thing about this is that if SOA SUite is down when the schedule is run you don't need to retry, it will be picked up when it comes online again.

Query regarding cron expression in BPEL

Hi,
I am using the quartz scheduler in BPEL and using the cron expression in bpel.xml
but the problem I am facing is it is running for only one day it is not running for the next day
the expression I am writting in bpel.xml is
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" partnerLink="FileScBpel4" heartBeatInterval="10">
<property name="schedulerCallout">DefaultSchedulerCalloutImpl</property>
<property name="endpointScheduleOn">0 30 19 * * ?</property>
<property name="endpointScheduleOff">0 31 19 * * ?</property>
</activationAgent>
</activationAgents>
so if I deploy it in BPEL PM it will run for today at 19:30
but when I am changing the system date to the next day and changing the time to 19:30 it is not running again
can anybody plz help me out how can I schedule it for everyday 19:30

Hi Sailo,
If you use quartz as a servlet, you'll have to add the entry to you're web.xml, in addition to other servlets you create :
<servlet>
<servlet-name>QuartzInitializer</servlet-name>
<servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<init-param>
<param-name>config-file</param-name>
<param-value>quartz.properties</param-value>
</init-param>
<init-param>
<param-name>shutdown-on-unload</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>start-scheduler-on-load</param-name>
<param-value>true</param-value>
</init-param>
</servlet>

Best practice on calling an Oracle Bpel process

Trying to find the best practice calling an Oracle Bpel process. I know that I can call the process via database, app server, anothe bpel process, from an application, cron job, etc... I can do any of these but want some feed back on what others do and what method is the best.
Thanks

Your right there are a lot of different ways to call the BPEL WS. I guess what I'm asking is if you had several of these options at your disposal what way would you choose?
I have an asych bpel process that needs to be called once a day to move some data from one db to another. What do you think is the best way to perform this: from the db cron or Oracle job scheduler, the bpel manager on a timer, etc. I'm leaning towards calling it from the db via a cron or an oracle job. Want to know if there is a best practice for something like this.
Thanks

How run reports JDE from BPEL using the Adapter for JD Edwards OneWorld?

Hi,
I need to load on line a lot of invoices from Bpel to JD Edwards using the Adapter for JD Edwards OneWorld (iWay).
Using Business Functions as Web Services it wasn't a not good idea because of this Adapter is poorly constructed and doesn't allow simultaneous loads, a memory leak occurs on JDE server. And to load them invoice by invoice is very slow.
A choice is to use Z tables and load them through schedules, but Bpel loses total control.
I heard that I can run processes reports that enable to extract the data from the Z tables and load them into JDE.
How can I execute reports JD Edwards invoked from BPEL using the Adapter for JD Edwards OneWorld?
Thanks
Francisco

Hi Dario,
BizTalk 2013 R2 (JDE LOB Adapter) is not tested against latest release of JDE EnterpriseOne 9.1.
It only supports with 8.12 and 9.0 version of JDE.

BPEL(SOA11G) and Quartz

Hi Gurus,
Would you please help me in scheduling the BPEL process in SOA11G using Quartz.
I went through the old documents but they talk configuring on OC4J and to configure bpel.xml but i don't see any bpel.xml in SOA11G. Also the application server used now is Weblogic 10.3.1.
