Transient and Durable Process

Can anyone explain me what is transient and durable bpel processes are?

Senthil, as far as my knowledge no such information is stored in database.
Sundar, what is your goal? We normally work with our simple sync and async terms only. Transient/Durable or one/two way invocation are the ways to categorize the BPEL Process and its activities to improve the performance. I request you to study BPEL Threading Model. You can refer the OTN page http://download.oracle.com/docs/cd/B31017_01/core.1013/b28942/tuning_bpel.htm and get more information.
As you will be aware, typical sync process is a single web service call where the process is initiated, executes the logic and sends the response back to caller. Till the response arrives the caller would be waiting for that (and timeout calculations would be going on). Synchronous are typical Transient process if the criterion in the above forum post is matched. But suppose, in any invoke activity the idempotent property is set to false (default is true), the BPEL process will dehydrate the instance soon after that invoke activity and this process is durable process. Hope this explains.
Ahmed is right, he writes that durable processes are long-living and initiated through a one-way invocation. There might be separate call back for such processes to send the response back to the caller process. Typical Async example.

Configuraing the Durable process in Oracle BPEL

Hi,
We are working on Oracle BPEL process manager version 10.1.2, in development mode with Oracle lite for the dehydration data source.
Requirement:
We need to create the long-living and durable process which invokes the Web Services deployed in the JBOSS and Weblogic application servers. The operation in these web services are Request-Response messages and takes about 5 minutes to give the response back. During the execution of process instance if Oracle BPEL server gets re-started We need the BPEL Server to resume the instance execution from the place where it had stopped when it went down.
Implementation:
We have created the Asynchronous business process to orchestrate the invocation of web services said above. And added the WAIT activity for 2 seconds to ensure the dehydrations points. Since the Web Services are invoked synchronously we had used the WAIT activity to set the dehydration points. When the server is alive during the complete execution dehydration happens perfectly and receive the final result after 10+ mins.
Issue:
When the BPEL server goes down during the process execution then it is not resuming the process instance from the place where it stopped.
Please suggest me what kind of configurations that i need to make to the process or domain so that when Oracle BPEL server re-started, it could resume the execution of active process instance.
Thanks in Advance.

Sync durable process:

Hello,
I have read all available documents, but still have some questions related to difference between different BPEL processes, especially Sync transient and Sync durable .. Does Oracle support Sync durable? If yes how do we develop a Sync durable process?
Any suggestions will be appreciated ...

Redeploy a Durable Process

Hi Guys,
Oracle SOA has a limitation for retaining the state for asynchronous instance in the situation of redeploying the updated Composite. If when try, it gives as error "Cannot re-deploy a durable process. A durable BPEL process cannot be deployed when the flag keepInstancesOnRedeploy is set to "true" "
On reading through the SOA documentation, it states that redeployment is not supported for durable processes. i.e. Asynchronous or Synchronous with Wait activity with keeping instances intact.
Is there any way for retaining the state of the running instance, while redeploying the Asynchronous processes? Any guidance will be a great help.
Thanks

you can try redeploying the application with different revision and try to migrate the running instances from previous revision to new revision.

You can check out the products and services tab on this website - follow the instructions and it will let you if you are still under warranty and also let you know how much apple will charge to replace the battery. Also, check out MacResQ.com and compare prices. I believe I read that Apple Stores will give you a 10% discount for a trade in and there are some online places that will let you trade up also.

If there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.

Also take this time to backup your users files off the machine if possible.

Can I mix Pages page layout and word processing together in one document?

Hello there ! I am quite new to Pages and I am desperate to learn as i want to get rid of everything being Microsoft
As you all know when you open Pages you can choose between page layout and word processing !
the thing is i thought that after using a page layout you could just go with word processing easily... well no, you can't, but i'm sure i'm missing something...
For exemple i really like the catalogue brochure and it would be perfect for me to start a project... but after a few pages, i can just add blank pages and if i want to type text, i have to add text boxes... i don't want that, I want word processing... and another thing in this brochure i can't add table of content because it is not by default in the template...
So my question is quite basic here, can we link Page layout and word processing without having to use text boxes and everything ?
Thanks in advance !
Have a good day

Alexander,
Welcome to Apple discussions.
The simple answer is no. What differentiates page layout from word processing mode is that the PL mode has no text layer. So everything that goes on the page must be an object of some kind. And any pages you add to a PL document must also be PL. You can't mix the two modes. One way around it is to start with a blank page, insert a text box, then stretch the box so that it covers the entire page. You can the type in it as if it were a text layer in a WP file. You can even capture that page so that you can add it automatically when you need it, or save it as a template.
As for building a Table of Contents, it appears that Pages only sees text styles that are on the text layer, which means it won't see styles that are in objects -- which means it won't work with a PL document. From being a long-time reader of this discussion group, I've noticed it's rare that someone wants to add a ToC to a PL document.
If you find that you're going to be mixing text and graphics, start with a word processing template. If you really like the Catalog Brochure, you could always copy some or all of its elements over to a blank WP template.
Hope this helps.

How to catch date errors and continue processing in a PL/SQL procedure

I'm updating a date field with dates constructed from day, month and year fields. The incoming data has many instances of day and month that are not valid dates, ex 11 31 2007. There is no 31st day in November.
I would like to write a pl/sql script to scan the table containing these values and log the rows that produce conversion errors.
I thought I could do this with exceptions but there are no exceptions that correspond to the ORA-01847 error for mismatched day and month.
Here is what I tried (the print procedure is a local wrapper for DBMS_OUTPUT.put_line):
PROCEDURE date_check IS
start1 DATE ;
BEGIN
select to_date(nvl(yearcollected,'9999') ||'/'|| nvl(monthcollected,'01') ||'/'|| nvl(daycollected,'01'),'YYYY/MM/DD'))) into start1 from incoming_data where id=1 ;
     BEGIN
          update temp_test set test_date = start1 where id=1 ;
     EXCEPTION
          WHEN OTHERS THEN
          print('Date error message from exception block');
     END;
print('Processing continues after handling date exception') ;
END date_check ;
Is there a way to catch this kind of error and continue processing after logging a message?
-=beeky

Hi, Beeky,
There are lots of different error messages associated with bad dates. Rather than try to catch them all, I use a BEGIN ... EXCEPTION block that contains nothing but a TO_DATE call. This is one of the rare occassions when I think "EXCEPTION WHEN OTHERS" is okay,
The following function comes from a package. If you want to make a stand-alone function, remember to say " *CREATE OR REPLACE* FUNCTION ...".
--          **   t o _ d t   **
--     to_dt attempts to convert in_txt (assumed to
--          be in the format of in_fmt_txt) to a DATE.
--     If the conversion works, to_dt returns the DATE.
--     If the conversion fails for any reason, to_dt returns in_err_dt.
FUNCTION     to_dt
(     in_txt          IN     VARCHAR2                    -- to be converted
,     in_fmt_txt     IN     VARCHAR2     DEFAULT     'DD-MON-YYYY'     -- optional format
,     in_err_dt     IN     DATE          DEFAULT     NULL
RETURN DATE
DETERMINISTIC
AS
BEGIN
     -- Try to convert in_txt to a DATE. If it works, fine.
     RETURN     TO_DATE (in_txt, in_fmt_txt);
EXCEPTION     -- If TO_DATE caused an error, then this is not a valid DATE: return in_err_dt
     WHEN OTHERS
     THEN
          RETURN in_err_dt;
END     to_dt
;

ABAP trail 7.00 timeouts and background process

Does anyone knows if it's possible to change the number of dialog and background processes?
And the transaction to change the timeouts of such processes?
Thank you

you can change the timeout in rz11.Parameter-name is rdisp/max_wprun_time. Backgound processes habe no timeout, so this value is only valid for dia-processes
To change the number, you have to adjust your instance profile. In the forum 'Netweaver Administrator' should be some information about that. So just the short hint: you can adjust the profiles in RZ10, but have to do some steps for that. Just search in NW-Admin-forum above.

Screen Sharing and WindowServer processes using 35-45% of CPU!!

I have recently relocated and reconfigured my Apple network and computers in the house :1) MacBook Air dual display MBA with 20" cinema screen in the office, and 2) and Mac Mini connected to a large LCD TV in the living room.
The plan now is to use the MBA as a primary computer and connect via wireless screen sharing to the MM so that I can monitor that system, run more intensive apps, watch EyeTV, file server tasks, etc.
But now this has increased CPU and fan activity on the MBA beyond what I would expect. The activity monitor indicates that the Screen Sharing and WindowServer processes are using combined between 35-45% of the CPU (screen share process is a constant 25%!!).
This is not good, and I wonder if it will be fixed in a future release. Any ideas or suggestions on how to limit the impact of screen sharing on CPU?

It seems to be running better with system update, and use of a faster computer (now using the higher end mac book air)
