The EJB 2.1 Timer Service & Clustering Behavior

With respect to WebLogic Server 9.0, does anyone know if The EJB 2.1 Timer Service will automatically restart a timer in the event of an entire cluster failure? Thanks,
-Matt

 Its possible that if you mark the server as migratable and have your
 store using HA then migration would work, although I'm certain that
 this has been tested.

Problem in using EJB 2.1 Timer Service

Hi all,
I need a method in my EJB to be called by the EJB container at regular intervals. For this I plan to use the EJB 2.1 Timer Service.
I did the following for implementing the Timer Service.
1. My bean class implements the TimedObject interface. Thus the method ejbTimeout(Timer t) will be called by the container according to the interval I define in the timer.
2. For defining a timer, I have created a business method in the EJB which creates a Timer object with the timer service.
public void registerTimer(){
     // getting the timerService from the EJBContext
     timerService = myContext.getTimerService();
     // create a timer which times out after 5 seconds, and subsequently after every 10 seconds
     t = timerService.createTimer(5000,10000,"my timer");
Q: Is this enough or do we have to configure the engine in some way, so that it calls the ejbTimeout() method ? Maybe I am missing out something.
If the above tasks are enough then according to my understanding, the timer is created and then the ejbTimeout(Timer arg0) should be called first after 5 seconds and then after every 10 seconds.
I have created a servlet which acts as a client to this EJB, by which I can see that the Timer object is created, but the ejbTimeout() is never fired .
What could be the reason behind this? Am I missing something? Do I need to configure the engine in some way?
Any input on the above will be most valuable.
Thanks and Regards,
Gagan Parhar.

Sharepoint 2013 search error - The search application 'Search Service Application 1' on server is not provisioned.Confirm that the Microsoft SharePoint Foundation Timer service and Central Administration service are running on the server.

Hi All,
I'm getting the below error in My SHarepoint 2013 search Administration page.
Crawler background activity - The search application 'Search Service Application 1' on server "" is not provisioned. Confirm that the Microsoft SharePoint Foundation Timer service and Central Administration service are running
on the server.
and when i click on Crawl Log and content source
it throws the below error
The search service is currently offline. Visit the Services on Server page in SharePoint Central Administration to verify whether
the service is enabled. This might also be because an indexer move is in progress
When i check the search status
Get-SPEnterpriseSearchServiceInstance, it shows all the components are online.
As of now search service application is online and search is working.But not sure why it throws the above error.
I have restarted timer service,search service in services.msc and cleared the sharepoint cache as well.
But no luck,This is happening in my prodcution environment.
Any help will be greatly appreciated.
There are the logs i have found

Please try below mentioned steps:
1. Central Administration > Monitoring > Review job definitions > Look for following timer job "Application Server Administration Service Timer Job" > Disable
2. Then open windows administrative services (services.msc), stop SharePoint Timer Service
3. Clear SharePoint Timer configuration cache by following steps mentioned in below blog:
http://blogs.msdn.com/b/jamesway/archive/2011/05/23/sharepoint-2010-clearing-the-configuration-cache.aspx
4. Start SharePoint Timer Service and give it a few seconds so that the new XML files from the location you deleted then are re-populated.
5.Central Administration > Monitoring > Review job definitions > Look for following timer job "Application Server Administration Service" Timer Job > Enable

Time service clustering in WLS8

          Hi
          Our product uses timer service on WLS 6.1, and timer is started by startup class.
          Now we need to move our product to WLS8 cluste. My question is: although startup
          class is clusterable, can timer service be clustered on WLS8? Or I can only start
          the timer in one server instance? If the timer is implemented using a stateless
          session bean which is deployed in the cluster, and one client in one managed server
          in the cluster starts the timer by calling the stateless session bean, will WLS
          support failover and load balancing of timer service?
          Thanks
          Chun


As Emily Lutella used to say: never mind!
It turns out the time service is simple, as we originally thought, and does
not distribute threads over scheduled trigger actions.
The mystery thread was started by a second server in the cluster going over
the wire to get to a bean on the first server.

We use the time service to schedule and process events at set times.
I just recently reviewed the documentation on this but still need a bit
more detail than I have seen, for example at
http://www.weblogic.com/docs51/classdocs/API_time.html
I am curious how multiple JVMs and threads may impact our scheduled
events.
We seem to have a situation where, when several events are scheduled to
occur at the same time, the first one waits on some resource such as an
EJB, possibly even getting into a deadlock with another thread that may
access the same resource(s), which may be running a JSP. But the time
service seems to move on, to process a second event scheduled for the
same time.
I would like to know more about how the time service allocates threads
to execute scheduled actions. For example, does it create a thread for
each action scheduled for a given time, or allocate a thread pool over
those actions?
If this is documented somewhere, I'd appreciate a pointer, otherwise
hopefully someone can provide more info here.
Thanks!

Stability of WLS 8.1 Timer Service?

Hi there,
Does anyone have anything to comment on the stability of the WLS 8.1
Timer service? One of our project teams indicated that BEA has a
whitepaper discouraging the use of the J2EE scheduler that comes with
WLS 8.1 as it might cause stability issues with the server.
Just wanted to know if anyone has any experience on this.
Cheers!

Do you think you can get a hand on this whitepaper..? we are using the

EJB Timer Service

I've been trying to get the javax.ejb.TimerService working. As stated in the J2EE 1.4 tutorial, it is possible to use the TimerService in an entity bean. In fact, it states that if I wanted a timer for each instance of an entity bean, to create the timer in the entity bean's ejbCreate(). However, I keep getting an IllegalStateException when attempting to do so. I have implemented TimedObject in the entity bean, so I'm a little confused. Here's my ejbCreate:
public String ejbCreate(String clientID, long timeout) throws CreateException {
setClientID(clientID);
TimerService timerService = context.getTimerService();
//dies on next line
Timer timer = timerService.createTimer(getTimeout(), "state 1");
return clientID;
Any help is appreciated....
Thanks
Raj

getTimerService is allowed in ejbCreate but Timer Service Methods are not . You can use Timer Service methods in ejbPostCreate(), though.

Clustered Time Services

Hi,
          I've got several time / schedule related services that are registered upon
          server startup. We are moving from a single server instance to a several
          clustered instances. As expected, I've run into an issue where each
          scheduled service on each cluster is firing independently of the others and
          thus I'm getting multiple notifications of each scheduled event.
          My question is this... how do most shops handle this type of situation? We
          want to have a scalable / failable? solution. I know I can take care of the
          problem by only registering the scheduled objects in a single per server
          properties file, but I lose any type of failover.
          I'm thinking of starting the scheduled services on each server in the
          cluster and binding a next run time into the JNDI tree. When a scheduled
          event fires it would check the next run time to see if it can run its
          schedule. If not it would reschedule itself to check later and effectively
          go back to sleep. If it can run it would do so and increment the next run
          time and reschedule itself to check later and go back to sleep.
          Any thoughts???
          Thanks in advance,
          Steve...

EJB Timer Services - timeout overlapping

Hi,
I have this question:
What should happen if the @Timeout method spends more time in working
something than the timer expiration time?
For example:
EJB timer is created with interval (expiration time) every 3 minutes. But for some reason the EJB binded to this timer is spending 4 minutes to process a timer notification. What happens with the next incoming timer notification?
Is it skipped or blocked? What happens with the method annotated as @Timeout?
Thanks!

Hi Fellipe,
This case isn't explicitly mentioned in the spec since the expectation is that the processing
time for the timeout would be much shorter than the interval itself. The design center for the
EJB Timer Service is to handle long-lived business processes so the spec examples for
timeouts are on the order of hours or days, even though the actual type in the API is
milliseconds. Many developers have expressed interest in support for finer-grained
timeouts and even cron-like functionality. The issue you raise would be an important one
to address in the scope of those EJB Timer Service additions.
Having said all that, the implementation in the Java EE SDK will not deliver a subsequent
timeout for the same timer until the previous one has completed.

How to replicate the EJB state between a clusters

We had developed shopping card EJB and deployed to a oracle AS clusters, and we want the EJB replicated its state such that the client is transparent to clusters failover. However, we try many times also failure.
Any brothers and sisters know how to do it????

You can check the chapter - "EJB Clustering" http://ftp.unex.es/oradoc/form_y_report_10g/web.904/b10324/toc.htm

At the top it says "No Service" and I have my SIM card in and a good WiFi connection and have connected it through iTunes but it says I have no SIM card and need to disconnect and insert my SIM. I don't understand why this keeps happening and it's been going on for a wile now. I have tried over and over again to get this iPhone to work but nothig is happening. I've even gone on the website for support (apple.com/support) but cannot find anything that will help me with this situation. Can someone please help me find a solution to this problem? I have been without a phone and do not have money to buy another one and it is crucial for me to get it fixed. Thanks.

What computer operating system is involved in the Premiere Elements 11 and 13 issues? Same computer or different ones? Are you installing from purchased download installation files or from purchased installation disc? Does Premiere Elements 11 work completely on this computer whereas 13 will not?
Let us go through the typical drill so as to take nothing for granted.
1. Does the problem exist with or without the antivirus and firewall(s) disabled? Are you working with an individual home computer or in a
school or company network?
2. Are you running the program as Administrator and is there any "domain" account involved?
3. Is your video card/graphics card up to date according to the web site of the manufacturer of the card?
4. Do you have the latest version of QuickTime installed on the computer with Premiere Elements?
Let us start by ruling in or out any of the above, and then we can decide what next.
Any questions or need clarification, please do not hesitate to ask.
Thank you.

Since you don’t allow emails any more – I suspect because of the numerous complaints with your service and the way you treat people that you don’t want documented, I am calling and I want this call recorded for future reference.
I have been a long time faithful customer of vzw and although the past year I have been late on payments many times and really couldn’t afford your exorbitant prices for services lots of other companies offer sometimes three times cheaper than what you charge, I have hung in there trying my best to meet my obligations.
This month has been no exception. You don’t know the background; the whole story of people’s lives. I know you could care less because all you care about is the profit-the money that comes in.
I was told when I agreed to pay my bill on the third per the recorded message that I had 14 days to pay…you cut me off anyway. The phones are not the tissue; your suspending my service means I cannot work. I may lose my job…how do you justify that? In any case? The least you could do would be to keep 4986 on and cut the phones off. But no. You refuse to compromise and meet the basic needs of your customer. What does that say about your company? I tried to call back on three separate occasions to tell you I couldn’t pay because of unexpected expenses but couldn’t get out of the automated system…sadly couldn’t get to a real person which also speaks volumes to me.
All this tells me this is a company I don’t wish to be affiliated with any more. As soon as I can, I will discontinue service with you…I know you could care less. I will honor the remaining portion of the contract but that’s it. You don’t deserve my business. I am a good, hardworking person who, at the sacrifice of myself and my needs, always pays her bills…albeit late at times. I realize others tell you stories and lies to justify themselves. That’s not me. If you knew what I had been through the last 7 yrs you would marvel that I am still on my feet…don’t judge too quickly. You could be wrong…and in my eyes you are by doing this to me.
God will see us through this extremely scary time of that I have no doubt. No thanks to your company and lack of understanding and mercy. I am doing the best I can. Sadly you are not.
See I have choices. MANY choices of providers for services you offer. I don’t have to be treated like this. I don’t have to succumb to your coldness and callousness. I intend to choose better (and cheaper). If your company doesn’t get the “people factor” back you will be sorry.

Problem here is you admit you cannot afford the service.
And you want to blame Verizon for losing a job because you have no cell phone.
If your job depends on that phone I would pay it on time every time if you need a job to pay your bill.
No other service is going to treat you any different. And if you cannot afford Verizon's monthly invoice how are you going to afford new devices, activation fees, possible security deposits on any other cellular carrier? You can't.
Also if you made an arraignment to pay and then decide you cannot do so, why should Verizon extend you service or credit, or why is it you want to use the service and data and not pay for it as agreed.
Get a prepay phone. Its evident the cost is too high for you to afford on post pay.
Good Luck

USELESS ONLINE HELP FACILITIES For all the amazing productivity aids that APPLE offers the world I have to report that their online support service is worse than useless and has recently been the source of immense time wasting and irritation.

USELESS ONLINE HELP FACILITIES
For all the amazing productivity aids that APPLE offers the world I have to report that their online support service is worse than useless and has recently been the source of immense time wasting and irritation.
Incident 1. Since many months attempts to download new and updated APPs produced a response – Apple ID Disabled. I had no time to consult an APPLE Store due to work in distant lands. When I finally visited yesterday I was told that as my IPAD has been reported as stolen, and APPLE in its wisdom had blocked its usage! I am not sure how they became so misinformed and nobody every advised me while with a few swift moves APPLE could have located me by email address or SKYPE.
Incident 2. Once the above anomaly had been fixed I tried to down load a newspaper and diligently input my address, credit card number and personal data. Repeatedly I was advised that my Credit Card was invalid and my postal code was incorrect! Really!
I was left to guess that having moved from UK to the US I should have advised APPLE! Not being told of this requirement brought about a second visit to APPLE Store in the same day to waste both mine and their time with a routine anomaly. How parochial in the context of a globalized world!
In each case I tried to resolve the issues using online access to a help line and by calling by phone at the numbers on the APPLE Website. In each of four separate occasions I diligently went through the routine and ended up with a message that thanked me for contacting Apple followed by a polite ‘Good Bye’!
In desperation I went to an Apple Store for the second time in a day as it is close to where I live when I am not working. On both occasions I was courteously attended to by Apple Staff.
However, my work is usually far away from the US and it is generally many thousands of miles to the nearest Apple Store therefore online help is viewed as imperative if one is to resolve issues away from home.
Why can Apple not provide a clearly marked EMAIL address and Telephone number at a Help Desk with real people to respond to requests for help? It would cost nothing in relative terms and might restore my high level of anti-APPLE sentiment that these two recent events have provoked.
Peter Hanney
Miami, Fl.

Why can Apple not provide a clearly marked EMAIL address and Telephone number at a Help Desk with real people to respond to requests for help?
If that is your question, the answer is at the bottom right of this web page. It is clearly marked "Contact Us" and is the best way, really the only way, to contact Apple.
If there were a publicly posted email address for concerns such as yours, it would be quickly filled with spam in about three minutes, thereby becoming instantly useless to you and everyone else. Apple would need to change it hourly, if not more often.

The article says that I should upgrade to the latest iTunes. I am on the latest iTunes version.
If you could read just a tiny little bit further, under the "Additional Information" section immediately after that, it says:
If you are still experiencing this issue when syncing, or have not installed Xcode 4 and get this alert:
Follow the troubleshooting steps in Mac OS X v10.5, v10.6: Resetting the SyncServices folder.
If the issue is still unresolved, follow steps in Sync Services: Advanced troubleshooting for contact and calendar syncing.
Have you tried those measures?

Are the WLS 9.1 Web Service Ant Tasks ready for prime time?

I am trying to create a Proof of Concept (POC) for Enterprise and B2B Services at Wendy's Int'l, Inc.
As part of this POC, I created a WSDL for an in-house service and then used the wsdlc and jwsc Ant Tasks to translate this WSDL to Java classes and ultimately (I hoped) a deployable services.
In this document, I describe the issues I encountered setting up what I consider to be a simple POC.
I'll try to attach my WSDL file and build.xml so you can follow along.
I'll also try to attach my CSS file so you can compare how the generated WSDL appears in the Browser to the way I want it to appear.
If attachments are not allowed on these forums, then I will wait and see if there is interest in those documents before I paste them under this topic.
Some preliminary information about my environment.
Environment:
 Windows XP Pro SP2
 WebLogic 9.1
 Java 1.5.0_04
Service Name:
 AppRelease
Note: If I modify my WSDL (perhaps to add a new Operation or to change the definition of an element) and run wsdlc again, the AppReleaseSOAPPortImpl.java file is overwritten For this reason, I implemented my service logic in a class called AppReleaseServiceImple.java.
Now, for the issues.
1. Bug:
In the WSDL generated by wsdlc, the wsdl:part child of the wsdl:message tag is erroneously prefixed with a colon.
This occurs whether or not I specify a prefix for the http://schemas.xmlsoap.org/wsdl/ namespace.
Work around: Extract the wsdl from the jar file, fix it and add it back into the jar.
2. Bug:
In the WSDL generated by wsdlc, the wsdl:input and wsdl:output children of the wsdl:operation child of wsdl:portType tag are erroneously prefixed with a colon. Like 1 above, this occurs whether or not I specify a prefix for the http://schemas.xmlsoap.org/wsdl/ namespace.
Work around: Extract the wsdl from the jar file, fix it and add it back into the jar.
The error message generated by Bugs 1 and 2 is not helpful in diagnosing the problem:
[jwsc] Error at line:46 col:7 ':' expected [?! -- [CDATA[ ]
3. Bug:
In the WSDL generated by wsdlc, the documentation elements have all of my html elements stripped out, as well as my xhtml and wsdl namespace references. This completely negates one of the best features of the documentation tag, being able to present the WSDL in a browser as a nicely formatted, human friendly document which is also the underlying WSDL that can be viewed when the person views the source document.
I label this as a bug because it greatly reduces the functionality of the resulting WSDL.
4. Annoyance:
The WSDL generated by wsdlc has all of my comments stripped out, except the comments in the xsd:schema section of the wsdl:types element. I would prefer that all my comments be left in the WSDL, but if comments must be stripped out then I think all of the comments should be stripped out.
5. Annoyance:
The WSDL generated by wsdlc has my CSS specification stripped.
Work around: I donâ€™t know if adding the CSS back will do any good because I have not yet created a deployable service (see the last issue below).
6. Annoyance:
The WSDL generated by wsdlc has different namespace prefixes than the ones I specified for my application's namespace and for the http://schemas.xmlsoap.org/wsdl/soap/ namespace.
Work around: Perform a find/replace on namespace prefixes "s0" and "s1" to return them to my prefered values.
Another thing I can do at this point is simply replace the generated WSDL in the jar file with my original WSDL. This would address issues 1 thru 6 above.
7. Annoyance:
The java source files created by wsdlc are put into a jar file. This makes it annoying when working within a traditional IDE like Eclipse because there is no way to reference the source files within the jar as working source.
Work around: Extract the source files from the jar and identify the resulting directory structure as part of the source structure of the project.
8. Bug:
The jwsc task complains if the same parameter name is used in multiple operations. I received the following Errors from jwsc:
[jwsc] C:\IDE\workspace\Acre-WL9.1\AppReleaseSOAPPort.java 0:0
[jwsc] [ERROR] - Parameter element "{http://acre.services.wendys.com/AppRelease/}garRequest" is not unique across document/literal bare WebService.
Since the operation names are unique, I see no reason to also require uniqueness in the parameter names used by those operations.
Work around: Use unique element names for the input parameters of the services operations.
9. Bug:
Once items 1, 2 and 8 above are taken care of, jwsc fails with the following error:
java.lang.AssertionError: java.lang.ClassNotFoundException: weblogic.j2ee.descriptor.ApplicationBeanImpl
This seems to be due to the weblogic.jar file not being in the System Classpath.
However, I should note that when I set verbose="on" and debug="on" in the jwsc ant task, there was a message from the task which stated "[jwsc] [search path for class files: [big freakinâ€™ jar list]". In the big freakinâ€™ jar list, I did find weblogic.jar and weblogic.jar has the required ApplicationBeanImpl. This indicates to me that the jwsc task does not fully honor either its classpathref attribute, nor an embedded classpath element.
Work around: Make sure the weblogic.jar is in the System Classpath.
10. Bug:
I fixed bug #9 by running a setDomainEnv script and then ran my ant task. This time I received the following output:
ant build-serviceBuildfile: build.xml
build-service:
[jwsc] 1 JWS files will be processed.
[jwsc] Processing JWS: C:\IDE\workspace\Acre-WL9.1\src\com\wendys\services\acre\AppReleaseServiceImpl.java
[jwsc] JWS: C:\IDE\workspace\Acre-WL9.1\src\com\wendys\services\acre\AppReleaseServiceImpl.java Validated.
[AntUtil.deleteDir] Deleting directory <some temporary directory>
BUILD FAILED
java.lang.ExceptionInInitializerError
At this point, I am completely stymied about how to proceed.
I wonder what new issues await once this 10th issue is addressed.
Really, is this tool set ready for prime time?

Sorry to hear you are having so many issues with using the WLS 9.1 web service Ant tasks, inside of Eclipse.
I generally create a User Library for the couple weblogic jars needed, and use it (the User Library) in my Eclipse projects that I create JWSes in. 
I also have a separate WebLogic Library in Eclipse (actually 2 libraries since I work with WL 8.1 and now WL 9.1). As you may know, one of the long-standing issues with the Ant integration within Eclipse is the fact that Ant, being an External Tool, does not receive the Project-specific Paths/Libraries. However, since most Java-relevant Ant tasks can take classpath and classpathref attributes, this is usually not an issue. In the case of the BEA-supplied wsdlc Ant task, it is apparent from the verbose/debug console output that wsdlc can see the jars in its classpathref, but it ignores those references when resolving class references and instead only uses the system classpath.

I've only needed the weblogic.jar and xbean.jar, not all the ones you mentioned in an earlier thread of this post. 
I have not tried to winnow down exactly which jars are required. I simply included all the jars that exist and were added to the system classpath by the setDomainEnv.bat file created by WebLogic 9.1.

Afterwards, I create an Ant Builder to build the JWS Web Service EAR, as opposed to fiddlin' with Eclipse. 
I too use Ant to build my deployable archives. Eclipse is simply my IDE of choice. I validated that all the issues I listed occurred when running Ant from the command line.

If you are interested in how I do it, send me an e-mail (to [email protected]), and I'll send you a zip of one of these JWS projects. The build.xml script for the project, takes care of a lot of the "annoyances" you mentioned, one of which I think is not accurate. I have never had a situation where the wsdlc Ant task "overwrote" my XXXImpl.java file.. 
Since I'm doing a POC to determine how we want to proceed with developing Web Services and an SOA in general, I tried to perform the same tasks using Axis 2 1.0, the WebLogic 9.1 tools, and XFire 1.1. Overwriting the Impl class is a common failing in the tools which take a WSDL and create Java source files for all three frameworks.

Try my scenario. Add another operation to an existing WSDL, and run the wsdlc Ant Task. The old IMPL class will be over-written.

Because of this, I have a separate Impl class and I make sure that all its methods and annotations match the methods and annotations in the Skeleton Impl class created by wsdlc.

Maybe that's because I use the <exec> Ant task with jar.exe (the xvf options) in my build.xml, to only get what I need out of the .jar/.zip the wsdlc generates. I'm typically only interest in the interface class that my XXXImpl.java file needs to implements, because I use XMLBeans for the input args (and return values) of my web service operations. 
Perhaps. I am not using XMLBeans in any of the three frameworks because the resulting service seems to be lighter-weight in all three frameworks if XMLBeans is not used. I'm sure there will be scenarios where XMLBeans is preferred, but I have not encountered that case in this POC.

Mike Wooten
Thanks for the follow-up.

Does the data transfer used in the back up in time capsule included in the data allowance from my service provider?

Is the data transfer used in the backup with airport time capsule included in the data allowance with my service provider?

I am using Ethernet cable to connect TC to the modem. I am only backing up my mac book air within range of the TC. So I guess it will be OK from your reply. As a trial I did interrupt the back up by turning off the TC, disconnecting the Ethernet cable, turning TC back on. The mac would not connect wirelessly with the TC without the Ethernet connection.
It is not using ISP .. absolutely for sure. Well 99.999%.. absolute tends to be only in maths.
But you did the test wrongly.. I said to disconnect the modem.. during the backup.. not turn off the TC.. obviously once interrupted the TC will not work again until everything is plugged in.. but it will work even bridged for a short time.. just unplug the WAN port from the modem.
The test is moot now.. as I can give you a 99.999% promise it is not using ISP.
