Result_cache_max_sizeis 0  after enabling AMM

I am using. Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production. After enabling AMM, the result_cache_max_size has become 0.
SELECT dbms_result_cache.status() FROM dual; Returns "BYPASS"
Following change was done to enable AMM.
ALTER SYSTEM SET MEMORY_MAX_TARGET = 17000M SCOPE = SPFILE;
ALTER SYSTEM SET MEMORY_TARGET = 17000M SCOPE = SPFILE;
ALTER SYSTEM SET SGA_TARGET =0 SCOPE = SPFILE;
ALTER SYSTEM SET PGA_AGGREGATE_TARGET = 0 SCOPE = SPFILE;
ALTER SYSTEM SET SGA_MAX_SIZE = 0 SCOPE = SPFILE;"
Note: shared_pool_size is 0.
I want to under how result_cache_max_size became 0 after moving to AMM. Does this mean result cache feature is disabled?

result_cache_max_size =0 means it is disabled.

    Mail isn't the only app using data. Turning it off there has no effect whatsoever on whether the rest of iOS or other apps you have installed. In fact most apps use data these days, at a minimum for Notifications and often for gameplay and other features.

  • Macbook pro does not boot after enabling Filevault

    macbook pro with OS 10.9.2 : after enabling encryption ran in to a problem and did not startup.
    did the followings:
    - loaded to recovery mode:  command-R
    - disk utility- verify disk> repair disk
    - tried to reinstall OS : did not work
    - re-partitioned the hard drive
    - tried to install it from bootable Mac os installation : it worked but after running the software update it did not start up again....
    - sent the mac to repair store to replace the hard drive with SSD  hard : they setup the hard with mac os 10.9.5
    - installed all the software update
    - enabled the file-vault " this time it finished the encryption but when started up and tried to login with user account it got frozen and did not work and so on ...
    - again tried to go to recovery mod and repair the hard and reinstall OS but it did not install the OS
    - had to again repartition the hard ...
    PS:  the macbook loads fine with the OS on External hard disk .
    this is really frustrating, can somebody tell me what's wrong with this mac why this issue happens after enabling encryption and why the issue is not gone even after reformatting the partition...

    I finally fixed the issue myself
    The macbook had a RAM issue:  Replaced the RAM and it is fine now.

  • Dbwr consuming high CPU after enabling DirectIO

    Hi,
    DBWR is consuming high CPU. After enabling DirectIO on Solaris SPARC 10, dbwr is eating away almost 1 CPU on a v440 machine i.e. 19% throughout the day. Neither of "buffer busy waits" or "write complete waits" or "free buffer waits" are in the top 5 wait events, which, to me, means that there is no buffer contention.
    What I understand is that after enabling DirectIO, it takes longer for the IO to complete because pre-DirectIO it would return from the file system cache whereas now it has to return from the disk (and I do see at the OS level that IO has become slow), but should that result in dbwr consuming more CPU?
    Infact after enabling DirectIO, IO has become very slow which is another problem and as a result log file writes have also become slow which is a 3rd problem. btw, I am aware that if there were many FTS, then DirectIO can make the system slow but there are no FTS in my case. Also, that SGA should be increased after enabling DirectIO, which has also been done.
    Thanks

    Yes, removing the file system cache from the I/O layer for a device can reduce I/O performance if the caller does not perform its own caching. However, direct I/O will eliminate the system cache overheads (and associated CPU resources needed) from a caller (like Oracle) that implements its own sophisticated buffer cache.
    Direct I/O should therefore increase Oracle I/O performance and decrease resource footprint as it eliminates the need for the kernel to maintain a cache for that device.
    Infact after enabling DirectIO, IO has become very slow which is another problem and as a result log file writes have also become slow which is a 3rd problem. Direct I/O, as per the Sun docs, is an advisory call. It may not place that device in direct I/O modes. It may result in partial direct I/O. So you need to make sure exactly what happens and how successful (partial or complete) this setting was.
    btw, I am aware that if there were many FTS, then DirectIO can make the system slow but there are no FTS in my case. FTS (multi block reads/large sequential reads) is slower? This is contrary to Sun's docs that state:
    Large sequential I/O generally performs best with DIRECTIO_ON, except when a file is sparse or is being extended and is opened with O_SYNC or O_DSYNC.

    iCloud's Calendar is full of errors and problems for me.  The "Couldn't move your calendars to iCloud because an error occurred" is now gone (by itself) but nothing syncs between my Mac's Calendar to iCloud or my iPhone to iCloud.
    I tried creating a new event directly on iCloud.com to see whether it pushes to any of my device and  got this "This event couldn't be created because of a server error; please try again." error.

  • Accounts getting disabled after enabling password expiration on BOXI R2 SP2

    Hi All,
    We have a strange issue with our production environment.After enabling password expiration on the enterprise some accounts got disabled,on further investigation I found that these users were either trying to log on to Designer or 2 tier Deski.
    I made them login through the Infoview to fix the issue.These users were Universe deginer or report writers.
    Any Suggestions

    Hi Tim,
    These accounts are Enterprise accounts,according to the users they were not given a chance and they never got any prompt for the password change it was disabled directly at the first login.
    These people were trying to logon using the Desginer or 2 Tier DESKI login and they are the members of the Administrtor Group also.
    Is it important to logon to infoview or 3 tier DESKI to change your password?
    I have no answer to give them why there accounts were disabled.
    Please suggest
    Thanks,

  • UPnP doesn't work after enabling Hyper-V role on WS2012R2

    Hi,
    We have stream/media player which use File share on WS2012 R2. It uses UPnP protocol to connect on File Share and it works fine. But, after enabling Hyper-V role on that server machine, stream/media player can't connect anymore on network share, cannot see
    any network computer, I would say master browser service is corrupted.
    Do you have advice, how to use UPnP on server with enabled Hyper-V role and virtual network adapter?
    Thank you in advance

    Have you tried doing things in the opposite sequence?  Try first installing and configuring Hyper-V and the virtual switches you will be using.  Then install the media player.  Maybe the media player is losing track of things when its underlying
    network is changed.
    Of course, Microsoft does not recommend this configuration.  It does not recommend running any other service on a host that is running Hyper-V.  That does not immediately imply it will not work; just passing on that what you are doing is a non-recommended
    configuration.

  • Getting error after enabling the Transaction in SSIS package in Windows Server 2008 R2 Standard machine

    Hi,
    I created a package with "Execute SQL Task and Data Flow Task". I am able to execute successfully in my server having

    Hi Sridhar,
    Please compare the DTS settings on the Windows 7 computer and the Windows Server 2008 R2 computer and make sure they are identical.  Make sure the “Allow Inbound” and “Allow Outbound” options are check, and pay attention to the authentication mode as
    well.
    Besides, make sure both Distributed Transaction Coordinator (TCP-In) and Distributed Transaction Coordinator (TCP-Out) rules in Firewall are enabled.
    If the issue persists and there are any security/anti-virus software, temporarily disable the security/anti-virus software and check the issue again.

  • HT1478 i get a message when trying to sync..."requried disk cannot be found" even after enableing disk use

    i get a message when trying to sync..."requried disk cannot be found" even after enableing disk use

    First make sure you are using the most up to date version of iTunes and have all the latest Windows updates/patches installed on your PC.  From there, try again and if still no luck, make sure you are plugging your iPod into a high powered USB 2.0 port.
    Otherwise try these steps:
    1. Run “c:\WINDOWS\system32\devmgmt.msc” (i.e. *Device Manager*), and leave it open for now for later use
    2. Start up iTunes
    3. Next, connect your iPod.
    4. Go to your iPod Settings and select the “Enable disk use” option from under theSummary tab.
    5. A dialog box will pop up reminding you that you’ll need to manually eject. Go ahead and hit OK
    6. Hit Apply to save changes to the iPod
    7. Quickly switch to the Device Manager window and right-click on any item within the window and select “Scan for hardware changes”
    8. Finally, switch back to iTunes, and try re-syncing your iPod to see if it helped.
    It might not also hurt to trash your iPod's Photo cache if it has one (i.e. you sync photos to the iPod).  See this article for information on where to find this folder on your Windows XP machine.

  • SQL server 2012 Ent using less memory than the allocated amount after enabling -T834

    I am facing the situation mentioned here.
    http://blogs.msdn.com/b/psssql/archive/2009/06/05/sql-server-and-large-pages-explained.aspx
    My SQL Server 2012 is not able to use all the 112 GB RAM that was allocated to it after enabling -T834.
    This was not the case earlier. Now I see the Total server memory and target server memory counters are just 27 GB constantly. I found the below error while starting SQL after enabling -T834. I restarted services again and this time it started fine. But I
    didnt bother about the error untill users complained slowness and SQL memory usage was found to be low.
     Detected 131068 MB of RAM. This is an informational message; no user action is required.
     Using large pages in the memory manager.
     Large Page Allocated: 32MB
     Large page allocation failed during memory manager initialization
     Failed to initialize the memory manager
     Failed allocate pages: FAIL_PAGE_ALLOCATION 2
     Error: 17138, Severity: 16, State: 1.
     Unable to allocate enough memory to start 'SQL OS Boot'. Reduce non-essential memory load or increase system memory.
    Now, SQL is started by its Total server memory is only 27 GB. How can I make SQL server use all the allocated max server memory with -T834 still on ?
    Bharath Kumar ------------- Please mark solved if I've answered your question, vote for it as helpful to help other user's find a solution quicker

    Hi Bharath , 
    in the below post the scenario is mentioned clearly 
    http://blogs.msdn.com/b/psssql/archive/2009/06/05/sql-server-and-large-pages-explained.aspx
    Unable to allocate enough memory to start 'SQL OS Boot'. Reduce non-essential memory load or increase system memory.
    This shows one of the problems with large pages: the memory size requested must be contiguous. This is called out very nicely at the MSDN
    article on Large Pages
    These memory regions may be difficult to obtain after the system has been running for a long time because the space for each large page must be contiguous, but the memory may have become fragmented. This is an expensive operation;
    therefore, applications should avoid making repeated large page allocations and allocate them all one time at startup instead.
    In this case above, even if ‘max server memory’ was set to say 8Gb, the server could only allocate 2Gb and that now becomes a maximum allocation for the buffer pool. Remember we don’t grow the buffer pool when using large pages so whatever memory we allocate
    at startup is the max you get.
    The other interesting thing you will find out with large pages is a possible slowdown in server startup time. Notice in the ERRORLOG entry above the gap of 7 minutes between the server discovering trace flag 834 was on (the "Using large pages..” message)
    and the message about how much large memory was allocated for the buffer pool. Not only does it take a long time to call VirtualAlloc() but in the case where we cannot allocate total physical memory or ‘max server memory” we attempt to allocate lower values
    several times before either finding one that works or failing to start. We have had some customers report the time to start the server when using trace flag 834 was over 30 minutes.
    regards,

    please help
    Since you have used an IP in the EM's URL, there can be one more possibility besides this that the EM service has been stopped(as suggested by others already) . It may be a reason that EM  service is not up because the IP address has been changed due to a machine reboot. As 9/10 times, the IP addresses are assigned via DHCP  on home laptops and desktops, if this IP address is no longer there, the EM service won't be up. But before we shall come to know about this that whether this is indeed the reason, try the command-emctl status dbconsole and if it says, not running EM, emctl start dbconsole. Post the output of the commands.

  • OIM 11g R2: Insufficent Privileges after Enable Database Vault

    oracle.iam.ui.platform.exception.OIMRuntimeException: IAM-7130125 : Search token caused Oracle text DRG issue, DB exception is :ORA-20000: Oracle Text error:

    this error occurs when i run Catalog Synchronization Job and i when try to search items in catalog
    i guess that database vault blocked the ctxapp role granted to oim database owner, but i am not sure how to fix it. Do i have to create a database realm for oim database user?

    As I continue to forage around looking for an answer, I came across the following statement in a document on Metalink: "The home where you plan to install ODV must already have OLS installed at the same patch level as the database.". Is this correct? I have never seen this in any Database Vault documentation.
