Tracking status of long running synchronous calls.

Flows 1 --- async call ----> FLows 2 ------ async call --------> Flows 3 -----sync call ----> axis ws
The last sync call can take a long time.
In the previous situation, i can't see Flow 1,2,3 evolution....
What i try to do :
I use the scriplet code setTitle() to show the flow status (RUNNING, USERTASK, SUCCESS) to show the flow
activity.
My example :
* Flows1 : setTitle('USERTASK')
* Flows 1 is waiting for a user task.
* User responds ..
* Flows1 : setTitle('RUNNING')
* Flows1 call Flow2 (flow2 call flow 3 ...)
* I can't see the Flow1,2,3 status until Flows3 end
so, the user will wait ...
Question is how can i force DB commiting while sync flow is called ?

David,
I created a project that mimics you use case and the title setting works as expected ( = the title changes and is visible through the console as the process gets executed).
Here is a link to a zip file that contain Flow1, Flow2 and Flow3 as described in your use case.
http://www.collaxa.org/TitleProject.zip
(deploy in the 3, 2, 1 order).
Does the attached project accurately describe your use case?
Thanks,
Edwin

Tracking completion status for long running DML operations

Does anybody know:
Is there any possibility to track a completion status for long running DML operations (for example how many rows is inserted)?
For example if I execute an INSERT statement which is working for several hours it is very important to estimate the total time for this operation.
Thanks forward

I'm working with Oracle8 in present, and unfortunately this solution (V$SESSION_LONGOPS)cannot help me.
On Oracle8 it works, but with some restrictions:
- You must be using the cost-based optimizer
- Set the TIMED_STATISTICS or SQL_TRACE parameter to TRUE
- Gather statistics for your objects with the ANALYZE statement or the DBMS_STATS package.

Long running database call

Hi
I have a scenario where a call to PLSQL is taking about 15+ minutes to complete.
Calls to database through database adapter is a sync call in BPEL, so yes the timeout is making the transaction JTA inactive.
I understand that increasing the transaction time out is not an option as the time to complete might vary based on amount of data to process.
What are the best practices for designing this scenario?
Every Little Help
Kalidass Mookkaiah

This is not a very good pattern as you have no viability of the second BPEL process, if this never gets invoked the first process will be none the wiser.
Plus how does your second BPEL process kick off the long running PL/SQL, once it gets invoked you still need to call the PL/SQL. How is this achieved using this pattern?
If you want to call a long running PL/SQL it can be achieved with AQ and correlations.
1.) Create an async BPEL.
2.) Invoke an AQ adapter that places a message on a request queue with a correlation id, so you need to use correlation sets.
3.) You setup your PL/SQL to subscribe to this queue, so when a message is posted the PL/SQL is invoked.
4.) Once complete it places the result on a response queue using the same correlation id
5.) Your BPEL process is listening for that correlation id on the response queue. (I like to respond with the status of the PL/SQL)
6.) Always best to have a pick activity after the receive so if the response is not within a timeframe you can implement some error handling.

Tracking progress of long running scripts

Hi,
I have a script that runs for more than an hour. It is a sequential list of queries/counts that produces an output.
I am finding that I only get the result if the whole script finishes.
If, for some reason, I have to abort the script, I can not see the results of the queries the script managed to finish.
I've tried using these methods:
1) (in a linux shell script)
sqlplus -s user@database/password @myscript.sql >> mylogfile.txt
2) (in myscript.sql)
spool mylogfile.txt
query1
query2
queryX
spool off
Is there a way for a list of queries to "pause" and save/commit the output to a logfile and continue with the rest of the script and append the rest of the results?
I hope someone can help me out.
Thanks,
Ian

Welcome to the forums!
Based on my experience you should be able to read a spooled SQL*Plus file while it's being written to. Maybe there is some oddity in your particular environment that is preventing that from happening.
An alternative would be to wrap each SQL statement using spool so you have one result per file. Then if you need to you can concatenate all the files together at the end.

Checking for status of a long-running BPEL process

Hi experts,
I have one BPEL process for originating customers' loan which usually involves various steps which takes around 15-20 mins to complete per instance. I would like to implement a user interface that can check the process's progress and display how it is going to the user.
I have thought of using an asynchronous process that updates a global variable listing status of each step inside the process and use a poller to invoke another operation (like "checkStatus" operation) of this process to retrieve this variable and display the value to the users. It may be achieved by using "OnEvent" activity waiting for "checkStatus" operation. It will run in parallel with the main process, have access to the global variable and reply this variable immediately to the caller.
It sounds like an idea in theory but invoking a web service operation for polling status is very heavy-weight and may impact performance during high-load.
I am just wondering if there is other solution to this problem as I believe the status checking is a very common expected requirement in long-running BPEL process. What might be the best practice to implement this?
Look forward to your responses.
Thanks and regards,

Hi.
I apologize for the slow reply. I am just back from overseas and did not have chance to go to the forum!
Thank you a lot for your responses!
The BAM looks like a suggested out-of-the-box solution. But it ties too much to Oracle API and will be hard to customise the way you want to interpret the status to end-users. If you want to display the process status with BAM in a web application interface, ADF is the only solution (please correct me if I am wrong). I would prefer a stand-alone, free of proprietary API solution so that we can build a screen that is technology-independent. As ADF UI is not our only supported view technology. For example, a PHP web client should be able to interpret the BPEL process status.
Will really appreciate your suggested solution.
Thanks and regards,

Challenging question: Status report for long running program...

Hi All,
With all the control stuff around like cl_dd_document I was wondering if there is a way to give a user a report which shows the progress of a very long running program?
i.e. If I have a 20 step process and each step takes 1 minute, the following is what I would like to occur:
Output a status line in a report format, run step, repeat until all steps are finished.
This is similar to the status bar, but with a history of what is happening. Obviously scrolling needs to be considered also. Ideally it would behave like sapinst would but in a reporting format.
Obviously this has to bypass the PBO/PAI approach, hence why I believe UI Controls must be the answer.
Any ideas anyone?
Regards,
Matt

Without using a control, you could try the old report refresh trick using set user-command and an action triggered after an RFC in a new task ... see basic demo below:

    start_end(10)       type c,
end of gs_step,
gt_step               like gs_step occurs 10,
g_step_number         like sy-tabix.

Call long running process and return immediately

Hi everyone,
Here' my problem : I am calling an onDemand application process when clicking on a button. It's a very long running process; and while waiting for the response my browser stops responding (white page).
So, is there a way to call a process and return immediately to the javascript. The process will set a field to a given value when it finishes. In javascript side, I can then check in a while boucle the value of this field to know if the process has ended.But I dont know how to return just after the application process call ...
Thanks and best regards,
Othman

I presume that you can achieve that by means of a batch job.
You can use an automatic page reload every X seconds until a certain "flag" (or similar mechanism) changes state and check it in a before header process. In the meanwhile you can display some animated GIF for instance.
Once the processing is completed you remove the reload timer from the header or you branch to a different page using a programmatic technique like procedure owa_util.redirect_url.
Bye,

Erorr calling long running sync web service

Hello
I have definied simple async process:
assign (from process input to ws invoke input)
sync ws invoke
assign (from ws invoke output to process output)
Sync Web Service is long running (few minutes). In order to avoid timeout I have accordingly set sync-max-wait-time property.
I have observed that after starting process instance I can't see it in BPEL Console (however I know it is working). Furthermore when invoke activity ends (so instance state must be saved in database) I can see following error on system console:
<BaseCubeSessionBean::logError> Error while invoking bean "delivery": Cannot ins
ert audit trail.
The process domain was unable to insert the current log entries for the instance
"2314" to the audit trail table. The exception reported is: RollbackException:

Hi,
There are 2 ways to work around the error that you are seeing.
Option #1: increase the JTA timeout of the underlying application server.
Option #2: in the bpel.xml of your process, add a "nonBlockingInvoke" property to the partnerLink representing the interaction with the long running service.
Option #2 should also address the fact that the instance is not visible in the bpel console.

Web.Show_Document does not work with long running reports

I am using Web.Show_Document() to call reports from Forms. Everything works fine for smaller reports. However for long running reports I do not get the output instead get the page "This page cannot be displayed.". On checking the job status on the report server I find that report is still running and completes after some time but by that time my http request has already timed out. What configuration do I have to change to make my long running reports work.
Thanks

So, looks like this is an IE issue. I need to add the form server site to my list of Trusted Sites. Once I did that, everything started to work fine. Thought I'd share in case anyone is really interested.....

Long running query--- included steps given by Randolf

Hi,
I have done my best to follow Randolf instruction word-by-word and hope to get solution for my
problem soon. Sometime back I have posted a thread on this problem then got busy with other
stuff and was not able to follow it. Here I am again with same issue.
here is link for my previous post
long running query in database 10gHere is backgroud of my requriemment.
I am working on Oracle forms 10g which is using package given below. We want to display client information
with order count basd on different status like Pending, Error, back Order, expedited, std shipping.
Output will look something like.
client name   pending    error   backorder   expedited   std shipping
ABC            24         0       674          6789         78900
XYZ            35         673    5700           0           798274
.There are total 40 clients . The long running query are expedited and std shipping.
When i run package from Oracle Form Developer it takes 3 mintues to run but when I run same query in our application using forms
(which uses Oracle Application Server) it takes around 1 hour, which is completly unacceptable.
User wants it be done in less than 1 mintue.
I have tried combining Pending,error and backorder queries together but as far as I know it will not
work in Oracle Form as we need a place holder for each status.
Please dont think it is Forms related question, it is a Performance problem.

Synchronous Call Timeout but the PO still created in ECC.

Hi PI Expert,
I have problem with synchronous call (Web Service -
> RFC). Sometimes if the processing time in ECC take longer time the webservice will throw exception timeout but then the processing stil continue in receiver communication channel until success.
So if you use SXI_MONITOR you can see 2 transaction, Sender web service error timeout and RFC success.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- 
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Stack>HTTP response contains status code 500 with the description Timeout Error while sending by HTTP (error code: 500, error text: Timeout)</SAP:Stack>
<SAP:Retry>N</SAP:Retry>
</SAP:Error>
But the RFC communication still able to continue until succes. Supposed to be both error if the sender communication channel timeout ?
- <ns0:Z_MM_STO.Response xmlns:ns0="urn:sap-com:document:sap:rfc:functions">

Please advise is that anything that i can check ?
Thank You and Best Regards

Hi Fernand,
The last parameter (syncMessageDeliveryTimeoutMsec) you mentioned is for general timeout setting of RFC receiver calls (see note FAQ RFC Adapter: https://service.sap.com/sap/support/notes/730870). That one seems high enough in your case
xiadapter.inbound.timeout.default is the default setting of 180 seconds, which is normally the default for all timeouts in PI.
Normally in icm there's a setting for the http port (e.g. something like icm/server_port_x prot=http,port=500xx,timeout=180,proctimeout=180)
Can you confirm that one is higher then 60 seconds? (Just saw you saying something about 60 seconds before editing the posting)
Best wishes
Sebastian

Using MDBs for long running transactions

Although MDBs are not the best vehicles for running long transactions, I am
          forced to use them for one such scenario (let's say for lack of a better
          pattern). In order to let my long running MDB (with Container Managed Tx)
          do it's chores I increased the time-out value to a higher number rather than
          using the default of 30 secs. Strangely, I was seeing
          IllegalStateExceptions in stdout. So I created a brand new test MDB with a
          Thread.sleep for 60 seconds, increased my MDBs timeout value to 120 secs,
          made sure there was only one MDB in the pool and ran the test again. I
          still see the below error after 30 seconds.
          I guess I should probably open a support case, but I thought I'll post here
          as well in case there's something I am missing.

Hi Adarsh,
          It may be that the transaction time-out setting in the descriptor
          is not taking effect. The tx is still timing out after
          the default 30 seconds, so the later attempt to call
          "setRollbackOnly" fails as the transaction has already
          rolled back The ignored descriptor setting is a known issue
          in some earlier SPs, but I'm not sure when and where it
          was fixed - so yes, contact customer support. The work-around
          is to set the default transaction time-out for the entire server to a
          higher value. (I'm not sure where to set this on the console,
          but the relevant JTA MBean field is "TimeoutSeconds".)

Long running servlet in a single node of a cluster

Good evening,
I am developing a J2EE application that consists of a number of web services that perform background processing of relatively long-running jobs. Status of the jobs actually need to be reported back to the SAP ABAP system, which we do via JCo. All communication back to ABAP occurs in a single long-running, JMS driven servlet. This callback servlet uses both a timestamp (last time status was sent back) or a count of status events to determine when to send data to the ABAP system.
All of this works great in a single Java instance J2EE configuration. However, when we introduce clustering into the configuration, we get one instance of the callback servlet per J2EE server process. Is there an easy way to configure the servlet so that it only runs on a single J2EE server process in one instance?
TIA,
- Bill

Hi Bill,
Launching manually threads even from a web container is also not recommended as good J2EE practice.
If each applications launches its own set of threads that may easily crash the server. Another drawback of such long running servlet is that you are blocking application thread from the server. One last point - it seems that you are storing the data in the servlet at some intermediate variables without any persistance. What will happen if the server crashes ? Can you afford to loose the data ?
I am not implying that you launch threads from the MDB. I am just saying that you could define that single MDB and send messages directly to it. You do the job there inside the onMessage, no new thread. You will be guaranteed that no other call will be executed. You are guaranteed nothing will be lost in case server crashes, you will not use resources even if there is no traffic.
Btw, please feel free to give me a phone call or write an email to further discuss the issue. You can take the details from your CSN I am currently processing
Best Regards
Peter

Long-running Batch eWay JCD - threading and stopping

I have a requirement to poll for files on a remote server, every few seconds, almost continuously. Furthermore, without making a connections every polling interval. In other words, connect once and stay running, If a file is found, send a JMS message to another service that will process the file, but keep polling for more files. Thus, a long-running service. This will tie up the thread?
Can I have an array of BatchFTP instances, and in each loop of the long-running process, check each connected instance for incoming files? Or can I only have one instance?
If the domain is shutdown, will this service shutdown nicely, if it is still in its looping process? If not, I could check another 'command queue' for a shutdown command, but now I have to add code to the domain shutdown script to send that shutdown message to the command queue. Could I instead, somehow check the status of another service in the same project to see if it is shutdown, and therefore know to stop the loop and allow it to be shutdown? I saw an example of a JMX command to check the status of an object. Is that the best way to check the status of a jcd from inside another jcd?
thanks, Pete

Hi Chris and thank you,
I also do not want to build and manage a long-running service, from a performance point of view. The owners of the target server want a file to be picked up as soon as it arrives (within 5 seconds), but they don't want FTP connections created and deleted every 5 seconds. They expect that we will make a connect() call, and then continually loop / poll using dirlist() method.
When I look at this requirement I also think of re-using it as a generic service - as long as I have a long-running service, I might as well use it for any other long-running, open FTP connections to other servers/userids. So in the same jcd instance, I would connect to multiple FTP servers and execute a loop where I go through a list of FTP connections, and for each, I would go through a list of folders that should be polled (using dirlist method). So I only have one JCD running for a long time but it could have multiple FTP connections open. That is why I am thinking of using an array of BatchFTP objects.
When your code shows a Scheduler eWay input, do you mean that the JCD will triggered by the first Scheduler message, but would then go into a loop, doing work, and performing a JMS.receive on that Scheduler queue for the 2dn, 3rd, .. nth Scheduler message? So because the jcd is still running, it still had all its objects and FTP connections (open), but its looping is controlled by the Scheduler message?
I'm running 513u3. I am worried about shutdown. I think it might not listen to a shutdown command. So that is why I was thinking about putting in some code at the bottom of the loop that would check, somehow, if a shutdown is in progress.
