Does the address returned by GetDirectBufferAddress() change over time?

Let say I have a direct ByteBuffer instance allocated from the Java side using the ByteBuffer.allocateDirect(capacity) factory method. This buffer instance lasts for the entire lifetime of my application.
Can the address of the buffer change over time, for instance after garbage collection passes?
In other words, when I pass a reference to such a direct ByteBuffer to native code through JNI, will GetDirectBufferAddress() always return the same address for the same buffer during the lifetime of my application? Or somehow can the GC relocate the buffer elsewhere and the memory is pinned only when a local reference to the buffer is passed to my JNI method?
http://java.sun.com/j2se/1.4.2/docs/guide/jni/jni-14.html#GetDirectBufferAddress doesn't tell much about it.
Thanks for any enlightenment.

  • Why does the state of my fonts change from time to time?

    Every few days/hours I have to go to FontBook and switch fonts off and on to have FileMaker Pro 5.5 behave properly with greek fields.
    I don't understand: if once I've setup my fonts how I want them, why do they change by the next time I fire up FMP 5.5?
    In any case, how can I set up my fonts once, and save them in a collection so that the next time a mess occurs I only have to click on the Collection icon and revert to how I want them? Sort of like clicking on a playlist in iTunes. So far, clicking on Collections I have created doesn't affect the on/off state of fonts.
    Many thanks, as always.

    Hi, Alex.
    Are you running any "maintenance" software that performs a regular system cache cleaning? If so, that will enable fonts you've disabled. See the "How disabled fonts are handled in Font Book 2.0 under Tiger" section of my "Undoing Font Book" FAQ.
    Cache cleaning should not be part of regular maintenance: see my "Maintaining Mac OS X" FAQ. It covers my advice on "regular maintenance" and dispels some common "maintenance myths."
    Good luck!

    Yes, if you do a fresh install of the operating system, it's like a brand new machine.
    No, if you restore from a backup like a bootable clone or TimeMachine drive.

  • SCEP date range reports change over time

    Not really sure how to title this, but here is the scenario. I have altered a canned report to run the first Monday of every month and dump a Word file w/links into a folder. The alteration of this report is simply changing the end date to be -30 from today.
    So I am getting a 30 day report of all computers that were infected. The report runs and looks to be accurate based on alerting I have setup. The problem comes when I take this report and start to drill down into the data using the links in the report. Let's
    say my report shows a virus name with an infection count of 3. I can click on 3 and see a list of PCs that were infected....well not so much. If between the time the PC was infected and the time I look at the report, any of the 3 PCs were cleaned of the infection,
    then they will not show up in the drilldown. So if a single PC was cleaned...the count still shows 3, but clicking on 3 only shows 2 computers now. This pretty much goes for any data on the main page.
    So essentially the report is pretty useless to go back in time and see detailed info on the incidents since the status of every bit of info in that report has changed over time. I am not a SQL person, but I did have one of SQL team look at the database and
    she can't see anywhere that she can pull archived data from. Any idea what direction I can point her in to get the type of reports I am looking for?

    Yes, I know this is an old post, but I’m trying to clean them up. Did you solve this problem, if so what was the solution?

  • Change over time setup between operations

    Hi,
    1) In the Discrete MFG process, there 2 operations. In between there is a change over time or cleaning up time.
    Where do we capture these change over or cleaning timings?
    2) If i have 2 simultaneous operations, how do we handle them in routing?

  • Change over time on production line.

    Hi Experts,
    We have a scenario where we need to schedule the orders also considering the changeover times on a production line from one product to another. Suppose I am producing product A on the line and my next product is B, say the change over time is 10 mins. But suppose if I am changing from product C to product B, then the changeover time is 15 mins. Similarly it is different from one product to other based on what will be produced on the line next.
    Like,
    A---->B is 10mins
    C----->B is 15 mins
    D----->C is 30 mins and so on.
    A big matrix exists for the same.
    Is there any way that I will be able to handle this in standard SAP? Ideas will be much appreciated.
    Regards,
    Sachin

    Hi,
    You need to maintain the Setup Group Key in the routing, and then in capacity levelling table you group orders by this key, and then there's a function to reduce/change setup time for each order and for the group.
    Definition of Setup Group Key - transaction OP43
    Definition of Setup Matrix - transaction OPDA. In here you define the "new" setup times that substitute the "old" setup times, and are setup group dependent.
    In the routing opration detail in CA02 or CA01 choose the setup group key on the "general Data" part.
    For the capacity levelling part, it is too complex to guide you here.

  • Why does the correct return address not show up on outgoing messages?

    Hello,
    Specs:
    Windows NT
    iPlanet Messaging Server 5.1
    iPlanet Directory Server 4.13
    One user recently went through an account change (spam reasons).
    old uid: bob
    old email: [email protected]
    new uid: bsmith
    new email: [email protected]
    The problem is, that during testing, any email sent from the new account is arriving as having both the <Return-path> and <From> fields with the old email address.
    Keep in mind that this is not a client-specific problem as everything has been changed correctly (outlook) If an email goes from "Clients computer" >> "3rd party smtp server" >> "Hotmail" or the like, it shows up as having the correct return address.
    But the pickle I'm in, is that if an email goes from "Clients computer" >> "3rd party smtp server" >> "Our Server" , it shows up as having the OLD return address. - same thing if messages are sent internally (same server) through the webmail interface. The messaging server is somehow rewriting the email field when any message goes through it.
    What makes this a super-pickle is that this is a NEW account., not just a 'change' of the old one. The old account has been deleted, and the command 'imadmin user purge' doesn't find it, nor is there any reference to the old 'bob@' address in the ldif file except for an address book entry or two (other users have added 'bob' into their address book)
    Any help is greatly appreciated in advance. Sorry for the long description, but now all the bases I've covered are known.
    Sincerely,
    Josh

    Jay,
    I only mentioned SIMS 4.0 because I jumped directly from that to MS 6.0p1, and because what my customers wanted to do worked on SIMS and doesn't on MS6.
    To complicate things more, my customer has multiple domains, but not all employees have e-mail addresses in both domains. For example, Joe is [email protected], Jane is [email protected], and John wants mail sent to either [email protected] or [email protected] to come to him.
    I dealt with this by setting up abc & xyz as separate domains, and created a mailing list in xyz.com named "john" with an external member of [email protected] While this works fine, when I add an alias to that mailing list of "[email protected]" and John tries to send a message with "[email protected]" in the From, it is rewritten to [email protected] as that is his primary e-mail address.
    In looking at the LDAP entries of mailing lists that are not working as I'd like, I see that the aliases are specified as mailAlternateAddress attributes. Are you saying that if I change these to MailEquivalentAddress attributes that they will then show up in the From unchanged?
    Oh, and one more possible factor - they are sending mail using SMTP AUTH as they are roving users. Since the mail server knows that the authenticated user is truly [email protected], is that why his From of [email protected] gets nuked?
    Thanks,
    Bill

  • Mavericks After Upgrading to 10.9.2 the font size in the address/seach bar has changed to be small.

    After upgrading to Mavericks 10.9.2 the text in the address/seach bar on Safari is a lot smaller.  This is not a screen resolution issue. The fonts in Finder are larger than they were before anoying fix for this would also be nice. It is also not a screen resolution issue.
    I really do not know what Apple are doing with quality control with Mavericks.   The 3 month GMAIL problems have not been fixed with this upgrade and you also have a lot of font size changes accross you whole machine, within mail, finder and safari.
    Any help appreciated.
    Mark
    Message to Apple: 
    Mavericks reminds me of all the old problems I had with Windows before I moved to Mac. Prior to Mavericks upgrades would not change screen resolutions, Font sizes etc.   The GMAIL issue has not been fixed.
    It is inconceivable to me that you could release this product which does not support basic mail functionality for one of the largest email services on the internet ie. GMAIL and then take 3-4 months and still not fixed with the 10.9.2 upgrade. What are you guys doing. The loss of productivity for people is beyond comprehension.
    Can we please get a fix for GMAIL in Mavericks that actually works.

    Dear WD Registered Customer,
    UPDATE: November 1st, 2013
    As a valued WD customer we want to make you aware of new reports of Western Digital and other external HDD products experiencing data loss when updating to Apple's OS X Mavericks (10.9). WD is urgently investigating these reports and the possible connection to the WD Drive Manager, WD Raid Manager and WD SmartWare software applications. Until the issue is understood and the cause identified, WD strongly urges our customers to uninstall these software applications before updating to OS X Mavericks (10.9), or delay upgrading. If you have already upgraded to Mavericks, WD recommends that you remove these applications and restart your computer. If you have already upgraded to Mavericks and are experiencing difficulty in accessing your external hard drive, please do not save anything to the drive, disconnect the drive from your computer, and contact Western Digital Customer Service at http://support.wd.com/country/ for further assistance.
    The WD Drive Manager, WD Raid Manager, and WD SmartWare software applications are not new and have been available from WD for many years. However, solely as a precaution WD has removed these applications from our website as we investigate this issue.
    Sincerely,
    Western Digital
    THIS is very disturbing news from WD.

  • When I send a group email why does the address bar not present the names alphabetically?

    I frequently send emails to groups.  Sometimes, for one reason or another, I want to delete one or more contacts from the list that appears in the address bar.  Why does the list not  appear in alphabetical order and is there any way that I can edit my contact lists to make it do so? It means picking through a list one by one rather than scrolling down a list to find a contact in the correct order. 

    Basically I suggest you keep using Eudora.
    Like most of those moving now, they are unlikely to be happy with anything else. But then that is to be expected, you have clung to abondonware for 5+ years after it's replacement. People that dedicated are unlikely to be happy with anything else.
    The Business standard and professionalism are not based on the Eudora way of things. I suggest you stick undisclosed-recipients: into a google search box and get instructions on how to do things for all the major mail clients.
    Of note Thunderbird displays nothing in the To field, even though the undisclosed-recipients: is inserted in the outgoing mail.
    <blockquote>
    I have tried using Bcc, and indeed, the recipients are suppressed, but not as a group. I have to change every recipient address from To: to Bcc: manually.
    </blockquote>
    Perhaps if you use the buttons at the bottom of the contact pane to add the list to BCC you would not have to manually change anything. See https://support.mozilla.org/en-US/kb/addressing-email#w_selecting-the-entries-from-the-contact-pane
    I am interested however how when you added a list so it appears on multiple lines. All I see is he list name until after I press the send button and look at it in the sent folder.
    Most people use another address entirely in the to:, in conjunction with the BCC list. It verifies the list mail is sent by coming back and you can put whatever you like in the display name of the email address.

  • Does the NF980-G65 support RAID arrays over 2TB?

    Looking to build a new machine fro Windows 7 (and switch to 64bit at the same time), and the NF980-G65 seems to be the closest board to my needs, just a quick question, does the onboard raid controller support raid arrays over 2TB in size? I had a look at the manual and it has a section on migrating an array to a size over 2TB which would suggest it does, but I would like some confirmation as to whether it does or not.

    I've run into this problem with some raid cards when building servers for work, as they were unable to address raid arrays over 2TB and would not allow the creation of the array, I am wondering if the raid controller has the right level of LBA to create a 2TB+ array. I am aware of the need to use a GPT partition to have a partition of over 2TB.

  • Why does the address/status bar not work?

    After updating to 9.0.1, my status bar will not work, or my address bar. If I try to type in anything and press enter into the address bar, nothing happens. Also, I cannot press forward or back as they always remain grayed out. The only way I can get to a website is by pressing home, which is thankfully google. I have to google the url to go to it.
    Remembering now actually, I copied all the folders from the main firefox folder and pasted them into a new install of firefox (I had this problem actually before firefox updated). I was hoping that copying these folders would save my addons and etc. after I downloaded a new firefox and re-installed it. I put the folders back and firefox is still messed up :/
    I just want it to work more Q_Q

    That issue can be caused by an extension that isn't working properly.
    *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • Does The GroupWise Server Migration Utility Change Case?

    From what I've read, if I do a manual migration with dbcopy and use the "m" switch it will change the case of files (to lower) from the source server. Is this true?
    Also, if I use the Novell GroupWise Migration Utility will that change files to lower case? If not is there a way to make it?
    Thank you for your help

    Yes and yes :) The dbcopy -m switch performs lowercase and according to the documentation for the migration utility it also does the same:
    Performs an operation equivalent to GroupWise Check (GWCheck) with the storelowercase option to ensure that all filenames and directory names stored in the guardian database (ngwguard.db) are also converted to lowercase.
