Is there any way to refresh the zfs snapshot other than creating another on

Hi,
I want to use the zfs send / recv replication, after I create the snapshot and do send/ recv to the remote filesystem, is there any way to do send and recv from the same snapshot after making some changes to the original filesystem other than creating another snapshot every time before send / recv
Thanking you
Ushas Symon

No, you'd have to take another snapshot and then send it, but you don't need to save all the snapshots after you are done. If you script it out to take snapshots fairly often during the day, the amount of data would be small. You can also send to a file and then backup that file to tape or whatever, you wouldn't have to save a million snapshots. You can also look into OpenSolaris' Time Slider function.

  • Is there any way to get the server app other that through the app store. We do not have our system conneted to a network. I typical downloaded items on a non-apple system.

    is there any way to get the server app other than through the app store. The system that I need it on are not connected to the internet.
    We run a closed-loop network of apple systems and I tipically downloaded updates on a non-apple system that was on the internet.
    Any ideas?

    I did buy the server app, went to the app store to download it. This system I'm using for downloads is Snow Leopard 10.6.8, it shows that I can download it but only as an Install which says I need 10.8. I can't seem to find a way for it to just download as a package or .dmg file so that I can copy it to DVD/CD or flash drive.

  • Is there any way to get the files from other computer ?

    Hai all,
    I have 2 computers connected. I know the IP address of other computer. Is there any way to get the files from other computer. (for e.g. I want to get the files from specific folder. In Java netwroking is it possible? (Any programs)
    regards,

    Bro Take it easy.
    Think you need to send a Image file named ("abc.gif")
    now develop a server using ServerSocket and connect it in local IP and any PORT
    For example i think ur server is connected in "localhost" and 9000 port.
    Now make ur server educated using some commands.
    For example:
    FileName: <File Name String>
    [Means new file is sending by connected client]
    FileSize: <File size long or int value>
    [ So that ur server can determind about the total length of sender file]
    DataModeOpen
    [Now your client will send its image data, this command means your client software is sending data]
    fjadlkfjaofaijojfwoeiurfodkjflsajlfksa
    l23j4lj23lkjlasjfoq23j4rokjelfkjasldkf
    2o3j4lk2j3ljslakdjf2l3j4 l23kjlk23k4j
    DataModeClose
    [Means file sending finished]
    Close
    [Means your client connection is closed]
    Now develop a client supporting this command.
    For example(Server):
    String getFileName=null;
    long getFileSize=0;
    public handleCommand(String getCmd) {
        if(getCmd.startsWith("FileName")) {
                String[] splitData=getCmd.split(":");
                this.getFileName=   splitData[1];
                outPutStream.writeBytes("+OK");
        } else if(getCmd.startsWith("FileSize")) {
                String[] splitData=getCmd.split(":");
                this.getFileSize=Long.parseLong(splitData[1]);
                outPutStream.writeBytes("+OK");
        } else if(getCmd.startsWith("DataModeOpen")) {
               //data mode open so receive data
              receiveData();
              outPutStream.writeBytes("+OK");
        } else if(getCmd.startsWith("DataModeClose")) {
              //close client socket
             getClientSocket.close();
    }For client:
    DataInputStream dataIn=null;
    BufferedOutputStream bout=null;
    public sendFile(bytes[] getBytes) {
            //if ok found then do other or show error message
        if(sendCmd("FileName:"+getFileName)) {
            if(sendCmd("FileSize:"+getFileSize)) {
                if(sendCmd("DataModeOpen")) {
                   bout.write(getBytes);
                } else {
                   showError(3);
            } else {
                   showError(2);

  • Any way to set the sort order other than in the query?

    The report has an OrderBy parameter so the user can select which field is used for sorting. The query has an OrderBy clause referencing the parameter. The problem is that it doesn't always pay any attention to the parameter. (Since it appears to be intermittent my suspicion is that it really never pays any attention to it but that sometimes whatever actually is determining the order gives the same results.)
    The problem is that putting an OrderBy clause in a query is the only way I know of to determine the output order of a report. Is there any other way?
    Thanks.

    Unfortunately Break Order doesn't seem to be controlling the sort order. I found that the value was set on numerous fields but I've changed them all to None & it still isn't displaying in the order specified by the OrderBy parameter.
    Note that this is a 'form layout' report with one page/record so it doesn't really have columns-but the pages are supposed to be printed in the order chosen by the user from a list of values. It doesn't seem to matter what's selected from that list though, the output appears in the same order as if no Order By clause is specified.
    Can you think of anything else that would cause the report to ignore the order by clause?
    thanks.

  • Is there as way to set the Status Byte, other than ibrsv?

    I am trying to emulate an instrument that sets the status byte to 64, but does not assert the SRQ line. Using ibrsv asserts SRQ, which seems to cause problems with my legacy test system. I am using LabWindows/CVI under Windows NT and a PXI-GPIB.

    Hi,
    According to the IEEE 488.2 standard, bit 6 of the status byte register (value 64 or 0x40 hex) indicates that the instrument is requesting service. Usually setting this bit will automatically assert the SRQ line. The NI-488.2 does not provide a function that just set this bit without the interface asserting the service request line.

  • Any way to refresh the calendar?

    iPhone 3G with MS Exchange Email, Contacts & Calendars set to manual fetch ...
    In my mail Inbox, I can press the refresh button in the lower left to update the Inbox. Is there any way to do this in Calendar (other than changing my Fetch settings) or do I just have to open the Calendar app and wait for it to update? TIA.

    You just need to exit then re-open the calendar app. With Push set to OFF and Fetch set to Manual, launching the app is what triggers a connection to the server. Mail is the only app with a 'check now' button.

    but it seems there is no option in oracle it self which can be used as there they are saying to get a data masking software which we can't due to some internal issues....I would not say that. How one implements masking depends entirely on the requirements that need to be met.
    For example, schema A owns all the tables. Schema B can be created as a "trusted" schema - in other words, schema A trusts schema B and allows it full access (with grants) to its tables. Schema B implements data masking as views. For each table in A, a view exists in B that implements the required masking. B can now grant select access on these views to user C. User C will see the same data object names in B as it would have if it used A - only, by using the B data objects it uses masked data objects and not the original source data objects.
    Another example - schema Dev is to have all the data objects of schema Prod, but masked where needed. One can use CTAS (Create Table As Select) to create the required tables in Dev with masked values where relevant. This Dev schema can be "refreshed" on weekends by dropping all tables and getting a new fresh copy of production data and masking it - ready for the next week's development cycle.
    If the application use is for example APEX, then instead of coding SQL directly as reporting regions to display, a function is used instead. APEX supports reporting regions where it calls a function and this function provides the APEX run-time with the SQL to execute and contents to render. It is easy to use this approach to implement logic in functions that masked column data depending on who the APEX user is, the security/role attributes of the user, and so on.
    No there is not a single "+mask this column!+" feature in Oracle.. but that does not mean that such a feature is not supported and cannot be implemented. Oracle has a very comprehensive and rich set of tools - more so than most (if not all) other RDBMS products.
    It is up to the architect/designer/developer to use this toolkit in creating a system that meets the specific requirements at hand.

    Hi,
    If you want to do any custom formatting to the workbook and you do not want it to reset when you refresh the workbook,
    You will have to You can deactivate the function for adjusting the formatting (Adjust Formatting after Refreshing) in the Display Options of the Query Properties.

  • Is there any way to prevent the OS from querying the Superdrive when start

    Just a random question. Whenever my MacBook Pro starts up (either from sleep or a complete/fresh start, the OS queries the drive slot to see if there is a disc present. While this may be normal behavior, it seems to slow down the start up process. (I rarely ever have a disc in the drive). Just curious if this, in fact, normal, or if there's something awry.

  • Is there any way to retreive the FileName in the mapping

    Is there any way to retreive the FileName and so that I can use that in my mapping. This is FILE2RFC scenario with NO BPM.
       I am using the adapter specific message attributes in the file sender CC.
    Thanks,

    Yes you can retreive it.  Create an simple user defined function in the mapping and use the following code.
    Imports: com.sap.aii.mapping.api.*;
    Parameter: String filename
    Paramter: String filename;
    filename = fileName + ".DAT";
    DynamicConfiguration conf = (DynamicConfiguration) container
    .getTransformationParameters()
    .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
    conf.put(key, filename);
    return filename;
    Or
    Just do whatever mentioned in this weblog:

  • Is there any way to repeat the last action on a new selection?

    I'm playing with Pages to see if I can use it instead of Word. I'm very expert with Word, just starting with Pages. Like some things, don't like some, but I think it's worth continuing to play with it to see if it will work for me. One problem I've been having is repeating an action. In Word, if you do something (in the particular situation I just had, it was deleting a row in a table), and then click on another place and do command-Y, it repeats what you did. Similarly, if you format a word as bold, say, and then select another word and do command-Y the second word will also be made bold. I realize the latter can be done in pages by selecting "emphasis" style for the second word, but I couldn't figure out any work-around for deleting the table rows (I tried selecting several non-adjacent rows, but "delete row" was greyed out on the actions menu). Any way to do this that I've missed?

    Thanks anyway. I'm sorry that Apple didn't include a "repeat" keyboard shortcut - going to the Inspector and then the actions wheel and then "delete row" time after time wasn't fun.
    I'm afraid I failed to communicate well about outline format - I didn't mean a bulleted or numbered list, I do know how to do that, but rather making a single character (or in my particular interest a symbol, the diamond and heart suit symbols) appear in outline text format. You can do it by going to format->font->outline, but if I want to do it for several occurrences of the same thing (or a few different things), it's not much fun to do it that way. But maybe I can define a character format that's outline and that will work. Still would prefer to have a keyboard shortcut to apply the character format though.
    Incidentally, while I'm talking about diamonds and hearts, is there any way to change the amount of space that gets put in after the diamond and heart symbols if you insert them using Edit->Special Characters? I write a lot of documents that use those symbols and lines end up unevenly spaced because of the large amount of space below each symbol (I've figured out a partial work-around - I defined a style for "body after suit symbol" that is raised enough to get the line spacing right, but that only works when I want to have a hard return at the end of the line with the suit symbols, since if the lines wrap, both lines have to have the same paragraph formatting. This problem isn't really Pages related - I have the same difficult with Word .

  • Is there any way to identify the particular socket connection is closed ?

    Is there any way to identify the particular socket connection is closed or not ?
    Any methods ???
    How can the program knows the connection is lost or some thing ...
    Is the socket throws some excpetions when there is no active connection ???
    namanc

    If you get an IOException when you try to use the socket, the connection was obviously closed.
    The correct way for an application to know if the socket was closed is:
    1) the server sends a message indicating that the socket should be closed
    2) the client closes the socket itself

  • Is there any way to get the height/width of an image before importing it in the indesign document.

    Hi All,
    I need to obtain an image's attributes such as dimensions (height, width in pixels) without placing image in indesign document.
    I have full path of the image (say abc.jpg is stored at c:\my pic\abc.jpg).
    I have obtained the IDFile for this image, tried getting size using GetFileSize() which correctly return size in bytes.
    Is there any way to get the height/width of image without importing it in the indesign document.
    Please, give me some hints. I have spent quite a lot time digging in CHM. I have searched in FileUtils, IDFile API's but found no method which serves this purpose.
    At this point I am clueless where to search next.
    Any help will be appriciated.
    Just a point to mention, I am able to get image height and width for an image in indesign doc though Its not my requirement.
    Thnx,
    D.

    You might be able to examine the contents of the PlaceGun after calling kImportAndLoadPlaceGunCmdBoss without actually placing the image in a document. Not sure, but would be worth looking at.
    Otherwise you will probably have to write platform specific code, ideally with a generic platform-independant wrapper (see SDKSamples/paneltreeview/PlatformFileSystemIterator).
    For the Mac, look at CGImageGetWidth() etc., not sure what the best option is for windows.
    Perhaps Quicktime could provide you with a platform independant solution.
