EAR Loading Order

Hi All,
I have couple of EAR application that need to be deployed in a certain order when WL restarts
(I am using WL 8.1 SP3). On the console there is a load order property that would suit my purpose but I would need a way to define that in the deployment descriptor. Is that possible ?
I could not find a tag that would fit that purpose.
Thanks for your help.

Thanks for your help.The Spec does not define load order of EARs because an EAR is
supposed to be a self-sufficient entity. So you will nee to use the
console or config.xml to set the order. The better solution is to make
sure that ears do not require sequencing or make them handle the fact
that the load order is undefined.

Parent-Child Apps and Classloading...Wrong load order?

Ah, everyone's favourite two oracle topics slammed into one. I've been using Oracle's parent-child application deployment for some time, to reasonable success in Oracle App Server 9.0.4. Though screwing about with the classloaders in this way usually fills me with dread, the benefits of developing child apps in isolation from the parent are excellent.
In general I have always deployed in the following way:
server.xml
<application name="msip-app" path="../applications/msip-app.ear" parent="default" start="true" />
<application name="msip-services" path="../applications/msip-services.ear" parent="msip-app" start="true" />
default-web-site.xml
<web-app application="msip-app" name="msip-web" load-on-startup="true" root="/msip" />
<web-app application="msip-services" name="msip-services" load-on-startup="true" root="/msip-ws" />
orion-application.xml (parent app)
<library path="./msip-web/WEB-INF/classes" />
<library path="./msip-web/WEB-INF/lib" />
(Note: this generic approach has always worked...)
Now I am trying to upgrade to oc4j 10.1.3.x, and I seem to be trapped in configuration hell. OC4J now appears to load the child application first, which inevitably screws up the classloader for the parent app. Surely this doesn't make any sense, as the parent app is the dependency and should be started first?!
I haven't discovered any way to control the load order for apps in the config files; the only workaround is to set the load-on-startup for the child app to "false". This is fine, until I redeploy through Oracle EM, which switches load-on-startup back to true. Again, there doesn't seem to be any way in deployment to control this parameter!
Why in the heck would oc4j have changed it's load priority for parent child apps? Is there any way to force load order through config? Am I just crazy and no one else has seen this?
Help.

Thanks for the reply. Gave that a look, but unfortunately, that link concerns a problem at a lower level than the one I've encountered. A classloading problem alerted me to what I believe is a bigger issue, namely that oc4j appear to be launching my child app before the parent app, and this consistently screws up the initialisation phases for both ear files. This appears to be an explicit decision in the Oracle app loader about which war file (parent or child) to launch first, but for the life of me, I can't find the offending code by decompiling oc4j.
If it turns out that this intentional, surely this must be a mistake? The parent app is the dependency and must be loaded first! or I missing something big...

Load order in wls 7 sp4

Hi,
I have a strange problem with the load order in wls 7.0 sp4. I have 2 ear files
ear1 and ear2.
I have one war file in each of the ear files. I set the load order of ear1 to
1000 and ear2 to 100. I see the load order in the console correctly, but I dont
see the value in config.xml. So, i edited the value and added it manually.
Even after that, I have the problem where a servlet in the war file of ear1 is
executing ahead of ear2 during startup.
Any ideas to fix the problem?
thanks

Alright:
So I wrote up a simple small isolated reproducible test case.
http://www.niffgurd.com/mark/work/blog/index.html
So this is a bug, and I have filed CR125989, you will need to contact [email protected]
to follow up on this.

if
you shutdown the server gracefully we flush the writes to the config.xml.
So after you manually added the values in config.xml you still are not
seeing the load order being honored?
So:
ear1 LoadOrder=1000
ear2 LoadOrder=100
You want ear2 to be loaded first and then ear1 to be loaded second?
Can you attach your config.xml and your portion of weblogic log that
shows
deployment?

ApplicationLifecycleListener vs. load order

Why isn't the load order reversed when shutting down a server?
We have a number of applications (EARs) which have implemented the ApplicationLifecycleListener. When the server boots, the different applications listeners start()-methods get called in specified load order.
But when shutting down the server the listeners stop()-methods are called in the SAME order. The logical would be the reverse order.
This causes big problems for us. Is there a workaround?

Not surprising. I've been fighting with BEA support/engineering to fix a similar issue with web applications since January(!). The first workaround that jumps off the top of my head is to use to use a single, custom listener that manages your other listeners and takes care of delegating the appropriate calls. Meaning that you'd only have a single <listener> element in weblogic-application.xml and that you'd have to come up with a way to configure the set of other listeners. This could be hard-coded into the class itself or you could use something like an external XML or properties file.

Application Load Order Problem in WL7.0

Hi,
I appreciate if anyone can point me how to diagnosis this problem.
I have two application (EAR) files, one has a MDB component and
another EAR has a stateless session bean for updating the database.
Upon a message is receivced, the MDB calls the session bean to insert
the data. Messages are being delivered continously. I need to ensure
the MDB EAR must be loaded LAST when WL is started otherwise data will
be lost.
I specified the correct DeploymentOrder attribute (the one need to be
loaded first has a smaller value) and set TwoPhase to true on both
applications. However the load order is still not working. Sometimes
the applications are started in the correct order but sometimes they
are not. The behavior is inconsistent. Everything looks fine to me, I
don't know what else to try.
Any ideas?
-Leo

Hi Bart,
Thanks for your suggestion. However, rollback the message delivery is
not an option for us because the JMS provider we use does not support
distributed transaction!! Our current solution is to save the messages
in a special queue on the JMS server and run a recovery procedure to
recover the data to the database in a later time.
-Leo
"Bart Simpson" <[email protected]> wrote in message news:<[email protected]>...
Hi,
How are you doing?
There is a programatic / declarative solution as well. If the MDB does get loaded,
then it will try to look-up the session bean. If the look-up fails we will receive
NamingException. If the creation of the session bean fails we will receive CreateException.
In either case, we can catch these exceptions. Now we have following choices
if the MDB is transacted:
o Explicity roll back the transaction using the context
o Throw a runtime error (actually considered a programming error)
Then configure re-delivery of messages. Now, the messages will be redelivered
and they won't be lost. This will only happen for a short amount of time until
the session is loaded.
For more information about JMS, transaction, MDB, redelivery, etc. please check
out: http://www.javaworld.com/javaworld/jw-03-2002/jw-0315-jms_p.html

Controlling JAR loading order in OC4J

I have a WAR file ,which contains 2 JAR files namely, BASE.JAR, IND.JAR(among others).
BASE.JAR is used in our base application and IND.JAR is the industry specialization of BASE.JAR.
IND.JAR & BASE.JAR do have many overlapping classes.
In my industry application WAR ,i neeed OC4J to load IND first and then look at BASE. that way i will always invoke the IND variant and then if a class is not in IND then BASE gets invoked.
how do I set this ? ( weblogic has a load order ,does OC4j have anything like that ?).
Thanks in advance.

Hello,
If your application can be packaged into an EAR file I recall sometime I employed the standard application.xml file (that tells the container to load each module in the order specified therein).
Nevertheless that addresses a deploy time issue, not runtime like this one. If you are using OC4J 10.1.3, you can edit the deployment plan for your WAR file; in the webAppClassLoader wizard you can change the "searchLocalClassesFirst" or "includeWarManifestClassPath" setting. By finding adequate values for those above and by using the shared libraries mechanism accordingly you may work it out.

Target Load order is not working properly in 11.2.0.2

Hi,
Mappings whihc are migrated from OWB10.2 version to 11.2 which contains multiple targets are not working in accordance with the target load order given in the mapping.
The order in which targets are loaded changes between execution.
To test is this a problem with migration we had created a smaple mapping containg 3 targets and mentioned loading order in each target table as well as in mapping property.
The order in which the targets are loaded was random. But when we have 2 targets it seems to be working. But for migrated maps this is also not working.
Is there any bug reported in 11.2.0.2 for this issue? Any help is highly appreciated.
Thanks and Regards,
Pnreddy

Target load ordering is set to false by default in 11.2.
You need to set it to true if you want your mapping to use it.

Undesired Load order of FLV and MP3s

Hello
I have added a scrolling Flash page with a FLV and several
MP3 files in each their own player to site below.
I have set the video to autostart.
The MP3s are set to not autostart.
When I export the FLA the swf nicely plays the video first,
and the mp3s are loading in the background simultaniously.
When viewing the page in Firefox and Netscape the same
happens, just as intended.
Problem:
But in IE and Safari all the sound files are loading first
(and not playing) and not until they are fully loaded will the
video start loading and playing. This results in viewing an empty
video window for a long time.
1) Is there are way to make all browsers load the video first
and play it first?
2) And in general manage load order of video and audio files
in a Flash file?
Thank you on beforehand.
ggaarde
http://www.corpstory.com/video.htm

no, the sounds wouldn't be playing until you used the start()
method of those sound instances or you assigned the source property
of your mediaplayer and you wouldn't want to do either until your
flv completed play.
in fact, it would be optimal to first load one sound: the mp3
that follows the flv. then when that sound completed loading, load
the 2nd sound.

Load Order in a mapping

any one has done a SINGLE MAPPING WITH multiple SOURCE TO multiple target
like      source a TO target a
     source b TO target b
     source c TO target c
in an order, which is first a should be feeded, THEN b and so ON...
we have load order in Paris to resolve this, I'd like to know is there ANY way we can do it with 10GR1

I dont think there is anything like load order in 10gR1 but when i had similer problem we sorted that out with use of process flow by spliiting the mappings.
If you know a better way out then do let me know.
I have come across a previous thread in the forum on the same issue which says that we can not control load control WITHIN the mapping and OWB decided it by default in the order in which objects are drppoed on canvas!!!!!!!!!!!!!!

SWF Load order.

Hello all,
I have a group of FC outputs that I have used to create a virtual tour of my client's showroom here:
electronic-lifestyle.com
But the SWF files I have linked in the FXP are loading from back to front. The last Page is loading first and the first loads last creating some issues. I have one more pass I need to maker to fix some glitches with the vertical scroll bar and several other points but I need to know if I can adjust the order in which the SWF files load into the page. I would prefer they load when called for but if that is not possible I would like to load from the first page to the last.
On an associated thought, is it possible to create a progress bar in FC or Flash that will give the viewer some feed back on the SWF files loading in. Right now the area is blank until they arrive.
I have a feeling that this level of control is something achieved in Flash Builder, not in FC. That is fine, I am planning on importing the file into FB to enable deep linking anyway but since there is no round trip function I figured I would get all of the FC work finished first, then go into FB and make whatever changes need to happen there.
It is starting to seem silly that the two programs were separated to begin with. It seems a natural evolution that Catalyst and Builder be joined into the same application sometime in the near future. Once the round trip issue is taken care of, why not just work toward combining the two apps?
Anyway, if someone could give me a pointer on the load order issue that would be wonderful.
Thanks,
Brett

Why did Apple OS loose the ability to adjust load order of login items

In OS X.3.9 I was able to adjust the load order of log in items.
I can't do this in OS X.4.11. I would like to adjust two items Mozy and Yahoo! Widgets so that they load last. Although all my log in items including them load they hesitate while Mozy and Yahoo widgets load. I would like to make Yahoo widgets load very last and Mozy next to last.

Another approach which might work would be to delete some, most, or all of your current set of login items and replace them with a single Automator workflow, one set up to open individual applications in a predetermined order.
The workflow would be comprised solely of separate *Launch Application* actions (from Automator's Finder library) and might look like this:
1) *Launch Application* -- click the popup button and select the first application you'd like to open.
2) *Launch Application* -- select the next application you'd like to open.
3) *Launch Application* -- 3rd app.
4) *Launch Application* -- etc, etc, until you reach the last application, which could be Yahoo! Widgets.
From Automator's File menu select Save As > File Format: Application, and add the saved Automator applet to your login items.
Good luck.

Not allowed to move load order of Control panels in System Preferences Tige

I post here because System refuses to let me post in Tiger forum depite my being a forum member since purchasing my G4-500 new just a few months after coming out.
The problem is associated with my PowerBook17" bought new March a year ago. I currently am running 10.4.6 Tiger.
On my G4-500 using Panther 3.9 I am allowed to drag and drop the load order of extension and control panel in System > Accounts > Startup items, at will.
If I try the same thing on my PowerBook 17" It want let me Drag or if I do get it appear to drag what it does instead is remove from the list.

Java Load Order

Hi All,
We are trying to override existing OOTB method through our custom component but system is calling the OOTB method only. Below are the ways we tried to call our custom component method, request you to advice us where we are making mistake.
Problem statement:
There is a method public void abc() in class SomeHandler. This is OOTB class provided by Oracle. This is getting used in service XYZ with action as 3:abc::4:null
We created a custom service handler CustomSomeHandler and overwritten this method. We also increased the load order of this custom service handler to 200.
We tried below approaches, but nothing is working.
1) Approach 1
public class CustomSomeHandler extends ServiceHandler {
public void abc(){
2) Approach 2
public class CustomSomeHandler extends SomeHandler{
public void abc(){
}

When you define a service handler, there is no loadOrder... there is searchOrder. Therefore, you need to set it a number that is lower than the method you're trying to override.
Also, make sure you're merging your configuration table to the ServiceHandlers table...

IM52-Load Order Budget Upload Program

Hi All,
I'm Working on IM52-Load order budget Change BDC Load Program.i'm using Call Transaction for it.
here i'm getting a problem while recording(With SHDB) the tcode IM52, It showing the error like 'no measure found'.
But the same error i'm not getting while creating manually(i.e., With out SHDB).
So i developed the program by own using technical information, instead of recording in SHDB .
and i ran the program, but i'm getting the same error "No measures Found"
can any one tell me how to develope the BDC program for IM52-Load order budgets change.
should i follow in different way instead of normal BDC programm?
Thanks in advance
Ramesh

Hi Caforio Claudio,
Pls check if you have (If the Investment Measure is Internal Order)
You performed the commitment carryforward for measures belonging to the investment program - KOCF
You performed the budget carryforward for measures belonging to the investment program - KOCO
which are pre-requisites for Budget Carryforward for Investment Programs...

Adding pre-mapping process breaks target load order

OWB 11.2.0.2 on Oracle database 11.2.0.2
I created a mapping that has 4 sources (views on external tables) and 4 targets (3 regular tables).
V1 => T1 (truncate/insert)
V2 => T2 (truncate/insert)
V3 => T3 (truncate/insert)
V4 => T3 (update/insert)
The above is the target load order. It tested fine.
I added a pre-mapping process (packaged procedure) that is unrelated to any of these source/target tables, but just exits or raises a failure to control whether the mapping should continue to run or not.
When I run it, the selected/inserted/merged counts are identical, but from what I'm seeing in T3 is that the order was update/insert followed by truncate/insert. I verified that the target load order remained the same.
Has anyone else run into this problem?

Hi,
For OWB 11.2.0.2 the target load order property will set to 'False' by default.
If this is the case you can not guarantee that the targets will be loaded in the order specified. It should be set to 'true'
Right click on your map and select configure -> Code generation Properties -> Use target load ordering set it to true.
Please note that you should have ODI EE licence and you must have installed OWB with Enterprise opton to set this property.

Pnreddy
