Lost reference in cluster

          Our app is deployed as cluster (two instances), recently we saw some errors as
          below. What's the cause of it, is it critical? Since it's labeled as 'info", should
          we just ignore it?
          Thanks in advance.

Tried to renew lease for lost reference

Hi
Oracle sessions get stuck on parsing all sessions accessing the same object wait
on "library cache pin".
We found one session coming from jdbc client waiting on "SQLNET message from client"
and holding all the rest sessions.
When we kill this session the problem resolves.
Following the port holding session with netstat, lsof and so on back to the jdbc
client side on different machine we only see error message connected to the same
port saying "tried to renew lease for lost reference". Our assumption is that
oracle lost connection with the client while locking a DB object when was doing
parsing and thus locked all sessions that wanted to access same object.
Did anybody encounter the same problem? How was resolved?
Thanks.

In testing the cluster failover capability, I disconnected the
network cable from one of the servers I was running in a cluster.
The system failed over properly. When I reattached the network
cable, the system added the server back into the cluster. However,
I continue to get the following message:
Tue Dec 12 17:34:51 GMT 2000:<I> <DGCserver> tried to renew lease
for 1 lost references
(s).
What is the cause of this message? What needs to be done to clean
up the cluster?Rich,
This message is printed when one WebLogic kernel tries to renew a lease for
an remote object from another WebLogic which has already been collected. It
makes sense that this might happen in the failure scenario you describe.
When the network is disconnected DGC lease renewals can't be sent and the
kernel exporting the object may therefore believe that the object is no
longer in use and collect it. When the network is re-established the remote
objects may be gone.
However the fact that you are seeing this message printed repeatedly is
troubling. You may want to contact [email protected] with the
description you provided here along with the following additional
information.
Are you seeing this message on the client or server? If on the server is it
on the server that was disconnected or on one of the other servers? What
version (including service packs) of WebLogic are you running?

Tried to renew lease on lost reference in logs.

          I am using Weblogic 6.1 SP1 with 2 cluster configuration. I am seeing a lot of
          "Tried to renew lease on lost reference" msgs in my logs. These msgs seems to
          be logged almost every minute.
          I would like to know what does this msg mean and how would I elimiate this msg
          from my logs.
          Any help will be appreciated.
          Thanks

I am relatively sure it has to do with RMI and distributed "garbage
          collection", so it may be related to some of your replicated JNDI entries.
          The other question is what is causing the problem in the first place. Are
          your servers under intense load or are the exec threads getting saturated
          (whether or not the other resources like CPU are saturated)?
          As far as the low-level RMI implementation, I know that Weblogic has its own
          implementation for significant portions of RMI, but I don't know much about
          the implementation, so it is hard to guess. You may be able to get some
          additional pointers from Prasad Peddada[[email protected]].

DGCserver messages in log... "Tried to renew lease on lost reference"

Hi,

Tried to renew lease on lost reference

Hi all,
Can anyone pls help me with the following issue?
I have encountered the following message.
<ExecuteThread: '3' for queue: 'default'> <> <> <000000> <Tried to renew lease
on lost reference: '388'>
After a while, the following message will appear.
<ExecuteThread: '15' for queue: 'default'> <> <> <000000> <Unsolicited error response
for: '-1'>
This shows the threads in the server are all used up.
I will like to know the cause for the first message to appear and how to prevent
it. Whenever this message appears, it is telling us the server is going to hang
soon. We have no idea how to fix this problem. Can anyone help? Thanks.

I know the "tried to renew lease..." message you were getting was just some INFO
message that the server sent out. I believe this message has been surpressed
in Weblogic 6.1 SP3.
Not sure if the other message is part of that. I've been running with the service
pack for so long that I don't remember. :)

Changed date and time and lost reference to proxy files

I had a batch of transcoded proxy files (from a Canon 550d) that had the wrong time on them. I used "Modify > Adjust content created date and time" to shift them by an hour. FCP now reports "Missing Proxy" for all of them. I've checked in the events folder and all the proxy files are still there, it just seems FCP has lost its reference to them.
I can re-transcode them but of course that takes a long time. Two questions: anyone any idea why this happened and is there a way to re-link FCP with the existing files?
Curiously I adjusted the time on some files that had been transcoded from a AVCHD source and these are still OK!
(Using V 10.0.5 on a 2011 MBA with LaCie Thunderbolt disc)

In the end I re-transcoded the files but I think this article may have been the answer:

Lost reference to some pics

iphoto seems to have lost a reference to some images. When I do a search for an image in the finder , the finder result says the photo is in a folder in the iPhoto library. iPhoto cant see just some of the files. I cant share this iPhoto library from my tower to my MBP because is cant find some missing files. How do I relink the file so iPhoto knows where the images are.............I wish it knew they are right in its own folder dagnabit.
thanks.

The ! or ? turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
The most common cause of this is User Activity in the iPhoto Library Folder in the Finder.
Have you altered, moved or renamed anything in the iPhoto Library Folder?
If you haven't, then try rebuilding the database. Hold down the apple and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
If that fails, then you likely have a damaged database file:
Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library (Right Click -> Show Package Contents) allowing it to overwrite the damaged file.
2. Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums back.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new library:
Note this will give you a working library with the same Events and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

Regernerating lost references with iDVD - Package Content

Hello all!
The situation:
I have some old iDVD projects which I would like to overwork a little bit. Meanwhile I am on iDVD'08 and some of the referenced images have sligtly moved from there original location. When iDVD starts up with such an obsolete project I have the occasion to search for the lost images in a convenient way.
How it was:
With former iDVD versions, I could specify a path from where iDVD starts to search. The search was rather fast and efficient, as I colud specify a path inside the "iPhoto Library"
How it is now/my question:
with iPhoto '08 its library turned into a package. I am not able to open the package (View packages content) using the small file browsing dialog box provided by iDVD in the mentioned serach dialog. Therefor all I can specify now, is the entire "iPhoto Library" as a starting point for the lost images. The search takes now forever as I have several thousands pics in my Library.
Has anybody an idea how I can speed this up? Is there e.g. a way to permamently open the package and move back to the regular file structure for iPhoto?
Or can I extend the functionality of the limited file browsing box and have it able to dive into a package?
Thx for any hints on that!

I just got a old iDVD project messed up by this poor implementation.
I guess nobody forced you to upgrade
Old applications/projects/etc don't remain compatable with new operating systems/applications/etc forever. I'm not an iPhoto user (for many reasons), but the non-destructive manner in which it saves modified versions with the same name has always bothered me. Couple this with the tendency of some digital cameras to reset the numbering system every time a card is erased or the batteries are changed and you get the kind of multiple file name confusion you are experiencing.
Does anybody has an idea?
Unfortunately, the best advice I can give you is to start over with a completely new project in iDVD '08.

How to restore Lost References ?

I moved my music data from an USB drive to a NAS drive in the network. This also changed the drive letter assigned to the iTunes Music Folder location.
I updated the location in iTunes after moving the files.
But iTunes does not find the files any more.
The file structure is 1:1 and the only thing that changed is the drive letter going from E:\... to L:\...
Any chance to get the references restored? Since I did make edits in the database (such as Genre, BPM, etc) and created many playlists I am wondering what kind of trick I can use or what I did wrong.
Thanks for any advise.

Lost updates in cluster environment known problem?

          we are running weblogic clustered. We have an entity bean that is set to read-write
          (which means that in clustering no caching will be used as per your docs). We
          are hitting this entity bean from both servers at the same time, an update by
          one, and a read by the other. What is happening is that the update appears to
          get lost for lack of a better term. We have the update in a method that requires
          a transaction, and after this method is finished (which means the trasaction/db
          commit has completed) we have a finder method that returns the updated record.
          Then, we shut down the servers and look in the db, the row has NOT been updated.
          We found something in your docs about "lost updates". It said to set the isModified
          method in the ejb to always return true, this also did not help.
          Okay, we found issues just like this in posts to the bea newsgroups from 2000.
          We tried what was recommended by Rob Woolen, and it worked. We set the <delay-updates-until-end-of-tx>false</delay-updates-until-end-of-tx>.
          This has stopped this from happening. Any thought? Is this really a true fix?
          Thanks all...


          We have db-is-shaed to true.
          Also, its not that one server is overwriting what the second server does, its
          that one server is doing multiple reads as the other server doing the update.
          Then the update never gets to the db, even after the servers are both brought
          down, its still not there, even though we do a find after the update tranaction
          completes, and it returns an updated row! Ugh...

Lost reference of main controller within popup

Dear all,
Within my application, I need to launch a popup to display some datas by using some attributes of my main controller. But when I launch the popupcontroller, I'm not able to retrieve the reference to my main controller inside the do_request of the popupcontroller. Does someone have a clue on it? Thanks..

Hi William,
when a popup is opened the controller which renders it will not have a reference to any other controllers because it is a complete new controller which was not created by a parent controller (you are opening the popup via javascript, right?).
So you have three options:
1)like Sergio suggested create an class with public static attributes which can be accessed from both controllers.
2)Create an application class because every controller has automatically a reference to this class (search for application class in the forum there are lots of hints how to do it).
3)Transfer information to the popup controller so that it can read the data which it should display by itself. For example call the popup like this: materialpopup.do?displaymaterialnumber=12345

Alamy plug-in lost references in Lightroom

One of my plugins has given me so much trouble that I want to delete it but it has lots of collections and presets associated with it.
I am minded to just delete my entire catalog and start over. Then I can tidy up all my presets and so on from scratch. I do have labels set which I want to keep and, of course all my keywording and develop adjustments. My files are .dng with metadata written to file.
I could just uninstall LR but I'd lose my set labels - or delete my catalog.
I'd appreciate any advice on how best to do this. Basically, I want to get rid of the preset and everything associated with it.
Message title was edited by: Brett N

It is is the Alamy Lightroom plugin which simplifies access and updating of files and syncing of keywords to the agency.
The trouble is, somewhere along the line the Alamy references have gone missing from LR and I really can't find the time to enter 2,500 references by hand in order to sync my libray with the Alamy info.
So I just want to get rid of the whole thing, including all the presets and replace it with keywords which tell me whether an image is on sale, whether it has sold and so on. I can do this manually.
But, being in the process of processing several hundred images and part way through it, I don't want to lose my labels. Other presets of mine I don't care about losing because I can use the opportunity to tidy them all up.
Would deleting my catalog be such a problem? I only have a few thousand images (I don't keep anything I cannot potentially sell). Thanks for your input, by the way.

Is there an easier way to create and cluster large numbers of references than doing it one at a time?

Hey, I have an instrument for which there are a large number of controls on a panel. I want to have the controls reflect the state of the instrument at the time the panel opens. I was planning on creating a sub-vi, then clustering a reference to each of the controls, then having the sub-vi set each value.
The question is, is there a way to highlight say... 12 controls, make a reference, and cluster them all together without the tedious process of creating 12 references, then wiring 12 of them into a cluster?
Or perhaps I should be using something other than clusters entirely?
Thanks,
-Josh

Writing values from control references is slow. Do not use it in high performance applications. Having said that, it sounds like you just want to do it once for initialization purposes, which is OK.
The answer is don't wire in a ton of clustered references. Just wire the a reference to the VI on which the controls live. You can get an array of references to all the front panel controls given the reference to the owning VI. You will need to "downcast" (to more specific type) for each particular data type, but that can be done inside the subVI. Note that the order of the reference array is the tabbing order of the controls on the front panel.

How to reference cluster by their string name

I have a program that contains 6 clusters of the same structure. I'd like to have a for loop to initialize the clusters to default values in stead of wiring 6 times to 6 different clusters. I've been thinking to programmably reference them by their string name, and then use an enum type to loop through their names. Is there a way to reference the cluster by name programmably?

You can get a list of front panel objects from teh FP property and then find the controls with the names you want.
SInce the refs to the objects will be generic array you will have to cast the refs so look over this nugget on using control references (stop after you find what you want, the nugget gets dirty at teh end).
Have fun!

Distributed Garbage Collector (DGC) messages in cluster when using Message Driven Beans

Version: Weblogic 6.1 SP2
          I'm seeing a lot of messages output on the node ** hosting my JMS
          server/destination ** in the cluster
          <Jun 4, 2002 5:35:03 PM EDT> <Info> <DGCserver> <Tried to renew lease on
          lost reference: '448'>
          Unfortunately, this message coincides with my MDB's ** on other nodes ** not
          being able to lookup the JMS destination that they are configured for.
          MDB's on the same node as the JMS server/destination are able to do lookups
          fine.
          Checking the JNDI tree on all nodes, I see the destinations replicated to
          all nodes. The MDB's use the default (i.e WebLogic's) connection factory
          (weblogic.jms.MessageDrivenBeanConnectionFactory) and I've bumped up the
          polling interval to 5 minutes from the default of 10 seconds.
          Any guidance on this would be greatly appreciated.
          I see that there is a patch available to fix the DCC info messages (April
          ,2002) on dev2dev. Anyone know if this addresses the MDB problem?
          Thanks in advance


FYI - in case anyone else sees this problem - it has been fixed in WLS 6.1
          SP3.
          If you are seeing this problem then you will see a log of
          NoSuchObjectException's in your console.
