MGP compose postponed because of unprocessed data in the in_queue

Could anybody shed some light on what does this mean?
"MGP compose postponed for B010MRM because of unprocessed data in the in_queue"
Thanks in advance,
dliu
We saw this one in the "Moblile Manager" Data Synchronization > MGP Apply/Compose Cycles > MGP History Cycle >
"Compose Error:
java.lang.Exception: MGP compose postponed for B010MRM because of unprocessed data in the in_queue
     at oracle.lite.sync.Consolidator$O8Server.fastPush(Unknown Source)
     at oracle.lite.sync.MGP$MGPG.run(Unknown Source)
     at java.lang.Thread.run(Thread.java:534)"

Basically there was data sitting in the in queue for the particular user when thier turn came around for the compose cycle of the MGP.
If this is the case, there could be a conflict between the incoming data and the data that could be selected from the main server database for download. To prevent this the compose will not run for the user.
During the next MGP cycle the in queue data will be posted first (assuming no errors) and then the compose will run as normal for the user. This is a relatively normal situation where there is a lot of incoming traffic and continual compose processes.

  • Blocking sessions during MGP compose

    We keep getting the MGP compose process blocked by inactive sessions
    We raised a SR with Oracle and they suggested adding the instance parameter DO_APPLY_BFR_COMPOSE=YES to webtogo.ora, but this does not seem to have cured the problem.
    From tracing, it seems that the problem is an inactive apply session that resulted in an error, being there for the user it is trying to compose. The actual block is on the table MOBILEADMIN.C$ALL_CLIENT_ITEMS.
    If an apply fails due to an error (eg: constraint violarion, trigger failure etc), it executes the statement
    UPDATE MOBILEADMIN.C$ALL_CLIENT_ITEMS SET CRR='Y' WHERE CLIENTID=? AND PUBLICATION_ITEM IN ( SELECT PUBLICATION FROM MOBILEADMIN.C$ALL_TEMPLATE_ITEMS ati WHERE ati.TEMPLATE=?):
    as part of the copy to the error queue. It also looks to execute the same statement at the beginning of the compose for the user, hence the block.
    The other odd thing is that looking at the blocks this morning, the MGP apply/compose kicked off at 7.09 am. The user synchronised at just after 8 am, by which time the MGP cycle was well into the compose phase, and there is no record of apply activity for the user within the cycle (the actual apply is in the following cycle), the the content of the blocking session was definitely apply code.
    MGP used to do all of the applys first, and then all of the composes, with a test to skip the compose if there was data in the user in queue. The upgrade to 10.2 (or one of the many patches since) looks to have changed the default behaviour to attempt an apply before each user compose, but the parameter above was supposed to set the server back to its old behaviour (ie: keep apply and compose seperate). NOTE i have not seen any of the old 'compose deferred because of unprocessed data in the in queue' messages in the compose recently either.
    Upshot is that it looks like it is still mixing apply and compose together, and where the apply hits an error, the apply thread is not closing correctly, or releasing its locks.
    Does anyone have any information about the parameters
    DO_APPLY_BFR_COMPOSE or
    SKIP_INQ_CHK_BFR_COMPOSE (this appeared with a value of NO when we added the other parameter.
    Information from oracle is that the two are mutualy exclusive (?) but they are not documented anywhere that i can find (the one reference on metalink leads to a non existant note), and oracle seem reluctant to supply any
    so PLEASE
    a) any information about the parameters
    b) any dependancies (ie: parameters not working because we are missing a patch)
    c) location of documentation
    d) any other ideas

    which version are you on?
    we are on 10.2.0.2, so unsure if this works in other versions
    The standard mobile manager parameters screen does not by default show these settings, but we were asked to add them into the webtogo.ora file in the [CONSOLIDATOR] section eg:
    [CONSOLIDATOR]
    # Installer will change these values
    SERVER_VERSION=8.1.7
    SKIP_INQ_CHK_BFR_COMPOSE=YES
    DO_APPLY_BFR_COMPOSE=NO
    RESUME_FILE_SIZE=512
    # 8.1.7
    # Installer won't change these values
    MAX_THREADS=3
    JDBC_DRIVER=oracle.jdbc.driver.OracleDriver
    once this was done we stopped and restarted the mobile server and then the new parameters will appear in the normal data synchronisation>administration>instance parameters screen
    our current setting on the live system are
    SKIP_INQ_CHK_BFR_COMPOSE YES
    DO_APPLY_BFR_COMPOSE NO
    and this does the compose whether or not there is pending data in the in queues for the client. Just my opinion, but there seems little point in doing the check as even if you force two tries of the apply process (one in the main apply phhase before the compose phase, and one just before composing for a particular user), the data in the second apply will not be picked up on fast refresh publication items as the 'snapshot' of the changes has already been done in the process logs phase

  • Windows server 2008 R2 Standard edition time server problem: The computer did not resync because no time data was available.

    Hello,
    I'm trying to get my 2008 R2 server (physical server) to synch with an external time server. I've read other threads on the topic but have not found a solution. I'm sure i'm missing something.
    First the step leading to the error:
    w32tm /resync /rediscover
    Sending resync command to local computer
    The computer did not resync because no time data was available.
    Following is the history: 
    Here are the steps
    C:\>netdom /query fsmo
    Schema master               DC-01.coastal.local
    Domain naming master        DC-01.coastal.local
    PDC                         DC-01.coastal.local
    RID pool manager            DC-01.coastal.local
    Infrastructure master       DC-01.coastal.local
    The command completed successfully.
    next: 
    w32tm /config /manualpeerlist:time.nist.gov,0x1 /syncfromflags:manual /reliable:yes /update
    The command completed successfully.
    next:
    net stop w32time && net start w32time
    The Windows Time service is stopping.
    The Windows Time service was stopped successfully.
    The Windows Time service is starting.
    The Windows Time service was started successfully.
    Next:
    w32tm /resync /rediscover
    Sending resync command to local computer
    The computer did not resync because no time data was available.
    Next:
    Did a restart of the server and repeated:
    w32tm /resync /rediscover
    Sending resync command to local computer
    The computer did not resync because no time data was available.
    Next:
    Ran the following:
    w32tm /query /configuration

    Hi,
    You may need to update command w32tm /config /syncfromflags:domhier /update, to change the IntranetServer w32time type to nt5ds (this sets the service to pull from the AD).
    For more detailed information, please refer to the thread below:

  • My ipod is somehow synced to another library, because I plugged the charger to a wall. How can I sync my ipod shuffle back to the original Itunes library without erasing my current data in the Ipod shuffle?

    My ipod is somehow synced to another library, because I plugged the charger to a wall. How can I sync my ipod shuffle back to the original Itunes library without erasing my current data in the Ipod shuffle?

    ",the owner sold the ipod without clearing the songs and since the songs were not puchased from the itunes store then i believe i now own the songs"
    Not true at all.
    It does not matter where the songs came from, they are not yours and the previous owner does not own the right to distribute them to others.
    The law is the same with downloads and cds and any other medium.

  • I can not transfer date from one hard drive to another, I keep getting an error because I have two of the same file names and one file name is in caps and I cant change the file name

    can not transfer date from one hard drive to another, I keep getting an error because I have two of the same file names and one file name is in caps and I cant change the file name. My original external has an error and needs to be reformatted but I dont want to lose this informations its my entire Itunes library.

    Sounds like the source drive is formatted as case sensitive and the destination drive is not. The preferred format for OS X is case insensitive unless there is a compelling reason to go case sensitive.
    Why can't you change the filename? Is it because the source drive is having problems?  If so is this happening with only one or two or a few files? If so the best thing would be to copy those over individually and then rename them on the destination drive.
    If it is more then you can do manually and you can't change the name on the source you will have to reformat the destination as case sensitive.
    Btw this group is for discussion of the Support Communities itself, you;d do better posting to Lion group. I'll see if a host will move it.

  • I unfortunately just got my IPhone 4s stolen.I thought I had the find my iPhone enabled but I didn't because I cannot locate the phone when I sign in ICloud.How can I erase all data on the phone so the thief can't access my personal information.

    I unfortunately just got my IPhone 4s stolen.I thought I had the find my iPhone enabled but I didn't because I cannot locate the phone when I sign in ICloud.I have a password on the phone but i'm not sure if I turned on the option where the phone resets if you incorrectly put the password more than ten time. I immediately called my phone company (Verizon) and reported the phone stolen.So I know whoever took the phone cannot place calls or use the phone. But can they still access my data on the phone if they manage to unlock the phone?  If so how can I erase all data on the phone so the thief can't access my personal information? is there any other way other than Find my IPhone to wipe off the data on the phone? I really don't want my personal information such as pictures, text messages, notes and social networks profile available to a stranger!!? Help please!!!

        Hello thewrongway,
    I'm sorry to hear about your phone!  I understand the need for an active device. You are able to activate an old device and process an insurance claim for your iPhone 4s within 60days from the incident date.  Keep in mind if the old phone is not a smartphone and you currently have unlimited data that feature will fall off.  If you have a tier data plan no changes will be made.  Please let me know if you have any additional questions.  Thank you.

    The Time Machines Backup is formated as Mac OS Extended (Case Sensitive, Journaled), my mac is formated as Mac OS Extended (Journaled).
    The names on the file are all Uppercase
    When I try to copy the Aperture file, it copies about 70% of the file (it's about 33GB in size), and halfway through I get this error.
    I'm able to copy 99.99% of all of the images if I open the Aperture Folder using the "show package contents" under the backups using finder (Time Machine Backups>Backups.backupdb>CQ Macbook Air>2012-04-30-070933>HD.....>Pictures>Aperture Library). The only file I can't copy is that picture, which I'm totally ok with deleting, but Finder won't delete it for me. If nothing else works, I could copy the individual masters and re-create the folders, however I'd hate to do this as I would have to go through 10,000+ pics

    I am backing up on two different drives...one is on the time machine...the one I am having trouble with is a passport that I back up manually.  I have not gotten a notice from the backup on the time machine that there is an error. 
    Before this error occured....the "event" that the photo was in emptied without me doing anything.  This has happened before, when the total number of pictures that I have downloaded for the day, the events emptied overnight without me doing anything (????????)
    Can you explain more what is happening.....

  • MGP Compose Timeout

    Hi people,
    When we try to sync about 80000 new rows to the server we receive the following in mgptrace_sys1.log
    log-1: ============== Server Exception - Begin ==================
    java.lang.Exception: MGP compose timed out for C2131_01
         at oracle.lite.sync.Consolidator$O8Server.fastPush(Consolidator.java, Compiled Code)
         at oracle.lite.sync.MGP$MGPG.run(MGP.java, Compiled Code)
         at java.lang.Thread.run(Thread.java, Compiled Code)
    ================== Server Exception - End ====================
    Does anyone know how to prevent this?
    Many thanks
    Andy

    This is expected, since the compose cycle for the user C2131_01 exceeded the default value for parameter COMPOSE_TIMEOUT, which is 5 minutes. I suggest two things:
    1. Tune the system to optinmize MGP performance (use the Consperf utiliy to get the numbers and explain plan)
    2. Increase COMPOSE_TIMEOUT
    The reason we did this is to prevent MGP from being blocked by one particular user
