Weblogic.time.scheduler

Anyone know why weblogic.time.scheduler is deprecated in 6.1 ?
and what is suggested to be used in place ?
Thanks.

In the next release, we're planning on providing an implementation of
the JMX timer APIs which will provide a non-proprietary interface for
accomplishing the same functionality. You should be able to use JMX
APIs in the server today via the java.management.timer.Timer class. In
the next release, we plan to have a version of this that is better
integrated in the server, and provides higher performance.

WebLogic Timer services.

WebLogic has deprecated Timer services with version 6.1 and recommend using Flux.
What is the rationale behind that? What do other scheduling services offer over the
standard JDK java.util.Timer class where I can kick of scheduled tasks?
Thanks ahead of time for your response.

Amit

.... but if done from startup, a timer is not in an app and thus can't see
the app's environment?

Hi,
I am trying to use the weblogic timer services.
I implemented the TriggerDef interface and deployed
the trigger using "Scheduler" and "Trigger" classes.
(Server-side triggers.)
However, when the trigger is run, will I be able to
do a InitialContext() without any parameters and use
it to do JNDI lookup? I am running into an error doing
that and am not sure if I am doing the right thing.

Monitoring Weblogic Time Service

Hello
I built a number of java classes that implemented ScheduleDef and
Triggerdef.
Then these classes are scheduled using WebLogic Time Service.
The question is :
Is there a way to query WLS to find out how many of these classes are
currently
being scheduled? We need to find out which one are no longer running in the
system
so we can reschedule them. But we also need to know if one is already
scheduled and
therefore disallow the ability to schedule a 2nd instance in the server.
Thanks

They did state a reason. They expect these services to become part of J2EE.
You can still use them, or check out something like Flux from Sims
Computing.

WebLogic Time Service

Hi,
I've created a time service on the server, which gets activated on
startup and repeatly occurs at some given interval. However, I need to
stop the timer and restart it again when the time interval is changed.
Is it possible to do that without bringing down the server?
Thanks,
TomyD

Mario -
I believe the way it works is you call the schedule () method of your WL
Time Services implementing object first. For example:
// Obtain a T3Services factory
T3ServicesDef t3 = getT3Services ();
// Request a ScheduledTrigger from the factory. Use
// this class for scheduling and execution
std = t3.time().getScheduledTrigger(this, this);
// Start the ball rolling
std.schedule();
Your schedule method would specify the point of time in the future in
which you are interested.
Your trigger method, when invoked, should set some instance variable in
your class. Your schedule method will be invoked after your trigger
method completes. When your schedule method is invoked, it should check
the instance variable and if it has been set, the schedule method should
return 0 to prevent the trigger from being called again.
Make sure that the schedule method is correctly setting the returned
long.
Oh --- your class should be implementing the Schedulable and Triggerable
interfaces, in case you were using something else. I agree that the
documentation for this feature seems pretty confusing.

As you can tell, I've been spending alot of time playing with Weblogic
time service lately, and needless to say, I've been running into alot of
roadblocks.
Question.
How in the heck do you implement the time api to perform a "one-time"
trigger for some point of time in the future? All of the examples, api
documentation, etc talks you through the necessary to perform
"recurring" actions. But nothing on one time actions. I have tried
several different variations but cannot get it done. Seems like the
trigger will immediately fire the first time but can be delayed for
future iterations till a specified point of time in the future using
java.util.Date methods.
Help!

ICal Week view, Date is not aligned with the Time(schedule) of each date

Well, just like it says over there (`` ). I've recently been to China for a business trip, and I suppose the different time zone may have had something to do with the problem. Now I'm back home, changed the time zone back to normal, still the iCal shows in the weekly view that the Date on the above is not aligning with the Time and schedule. Any suggetions would be grateful!!!

Hi,
i omit the scheduling maergin key in material master,
the result of MRP is
BASIC DATES
Finish 15.10.2009
Start 14.10.2009
PRODUCTION DATES
15.02.2010 14:33:25
14.10.2009 07:00:00
scheduling type i planned order is still "backwards"
so in MD04 it is say that the goods is available at 15.10.2009 same with requirement dates.
this seem not right.
it seems that order finish date is not adjusted by lead time scheduling on "today scheduling".
Is there a way so order finish date is adjusted by lead time scheduling on "today scheduling" ????

Hi Laura,
The RLT can be set in the Masters Materials.MMR and Also in the Documnet Type Configuration.
But as per SAP standard Procedure the Prority will be the document type.
That means the RLT given in the Order document will overseed the RLT given in the MMR.
Go to material master and select MRP3 view. There see what is maintained for "Strategy group". Now go to OVZG, select this Requirement Class and tick the field "Rq" against this.
Now go to OVZH, select your Requirement Type and ensure that the above Requirement Class is assigned to your Requirement Type.
Now create a sale order and check in MD04.
Hope ethis helps u..

Query on Time Scheduling ............................Urgent pls help

Dear Friends
Here is my query on Background processing,
I want to run a program in background which ll save the details in AL11.
I want to schedule this object between 12 AM night to 2 AM night as per the indian time standard.
The data should be save the data in al11 as the following format=>
1-It ll show the PO details that has been created between 12-1 and 1-2,it should not show 12-1 data in 1-2 means between 12 to 2 i ll store the data in AL11 that has been created between these one hour time if it would more than one hour than last one hour data it wont show in al11.
Now the Pos that has been created between 2 am to next day night should be display when the user ll run the report at next day 12 o'clock.
Can you give me the following idea,
1-Which table stores the background scheduling time,if NAST than what is the field name.
If anyone solve this kind of prob,pls help me on this.
Thanks a lot

Best practice using Using the WebLogic Timer Service

Hi,
We have a stateless session bean having a method which needs to be called lezs
say every 10 Seconds. I think the WebLogic Timer Service (JMX) should exactly
fit in this problem. So I would write a small class implementing the interface
NotificationListener which will receive the notification. The listener I would
register in my startup class.
This brings up some questions:
Could this class be a inner class of the SessionBean and directly calling the
method on the bean ?
Has it to be a more independent class gettting an initiali context, getting local
home, etc. etc. and then executing the method on the received Stub ? If yes can
it keep the Stub betwean the interval without releasing ?
Has someone experiance in this area ?
Regards
Tomy

Actually, it's bad practice to use break anywhere other than in conjunction with a switch statement.Presumably, if you favour:
boolean test = true;
while (test)
test = foo && bar;
if (test)
}overfor (;;)
if (! ( foo && bar) ) break;
}then you also favour
boolean test = foo && bar;
if (test)
}overif (foo && bar)
}Or can you justify your statement with any example which doesn't cause more complexity, more variables in scope, and multiple assignments and tests?

Time schedule in two languages

We are not able to create a time schedule in English and Russian. We created a user defined field to enter the russian description of the acitivity but this does not work for summary levels. For one print only one language is necessary so we wanted to replace the activity by the user defined field.
Is it a lack of the programme or are we doing something wrong?
Best regards
Tobias

What do you want then? Can you describe how you like to position the text?
In word processing document you can use layout breaks and column beaks to get two text columns beside each other.
You can also use text boxes, one for each language. You can even use Shapes as text boxes.

Need Automatic Lead-time scheduling in Planned Order using MD11

All,
Our users have a requirement that when they create a planned order using MD11, they would like system to do automatic lead-time scheduling based on the "basic finish date" entered by the user. Currently the system is taking 3 days from the in-house time maintained in material master to calculate the basic start date. But users want to use the 100 days that have been maintained in the routing.
Currently users have to click on "manual scheduling" on the planned order for system to pick up 100 days from routing which is an additional step for the users. Hence users want an automatic way in which system would do lead-time schedule when they enter the basic finish date.
Thanks,
Swapnil

Dear Swapnil,
In my understanding it is the standard SAP behaviour even if you have made the necessary settings in OPU5 for the planned
order type.
If my understanding is correct, then as per this setting the MRP behaves for the particular plant and order type combination.
Whenever you create a planned order manually you have to do a detailed scheduling and then you get the production dates
for the planned order.(This might be because generally when a planned order is converted into production order the system
carries out a lead time scheduling.- Check the same and correct me if I'm wrong)
Even if you update the material master through CA97,you will not get the detailed scheduling done along with the production
dates.So you have to perform this manual activity during MD11.
What is the reason of setting the in-house production time as 3 days,if the exact production time is going to be more?
Check and revert
Regards
S Mangalraj

Weblogic timer and ClassCastExcetion

Hi,
I have very strange problem. I have weblogic timer and when it's time to start the weblogic start's bean and all goes fine till get "home object" from another WLS where I get ClassCastException. Whot is funny if the same bean is started by stand alone client all works fine. I think that timer proces started by weblogic don't see classes that I'm trying to cast to. All classes are in ear file in APP-INF/lib.
What I have to do ??
Damian Grela

So I'm creating the timer(weblogic.management.timer.Timer) object in method ejbCreate() in InitBean.
Yes, when I invoke handling bean by stand alone client all works good.
