  • Saving a book as PDF takes significantly more time when the file binary *.fm rater than *.mif?

    Is it possible, that saving a book (with FrameMaker 10) as PDF takes significantly more time when the file is formatted in the binary *.fm rather than the *.mif format?
    We have books (+160p) that take about 20 min to be saved as PDF, whereas the same book in MIF format can be saved as PDF within about 4 minutes. Is this a known issue?
    Or could that be a problem with our books?
    Does anyone know how to speed up the process (how to tweak) or are there any special adjustments in the books or documents that might slowdown the process of saving them as PDF?
    The distiller seems not to be the problem. The distiller takes equally long for both formats.
    best regards

    Strikes me as peculiar. I would expect that FM is rendering from the data structures in memory, which I would expect to be essentially identical whether originally opened as .fm or .mif.
    If return-to-UI time is important, the fastest path is:
    print to local .ps file
    Distill separately.
    And it sounds like you have the full Acrobat product, and thus have full Distiller.
    I don't have sufficient experience with Print-to-PDF vs. Save-as-PDF to opine on potential time differences for those paths.

  • Is drop user cascade DDL statement will be reflected in physical standby DB

    Hi,
    Oracle 10G
    Physical standby database
    When issuing drop user cascade in Primary DB , Will the same be reflected in physical standby ? or there is any exceptions of applying DDLs and DMLs ?
    Thank you in advance,
    Mohamed

    Will the same be reflected in physical standby ?
    Yes.
    or there is any exceptions of applying DDLs and DML
    No, not in a physical standby.
    You do some exceptions in a logical standby.

  • Why the 'LIKE' operator takes so much time to run?

    I have a table T with 3 columns and 3 indexes:
    CREATE TABLE T
    id VARCHAR2(38) NOT NULL,
    fid VARCHAR2(38) NOT NULL,
    val NVARCHAR2(2000) NOT NULL
    ALTER TABLE T ADD (CONSTRAINT pk_t PRIMARY KEY (id,fid));
    CREATE INDEX t_fid ON T(fid);
    CREATE INDEX t_val ON T(val);
    Then I have the following two queries which differ in only one place - the 1st one uses the '=' operator whereas the 2nd uses 'LIKE'. Both queries have the identical execution plan and return one identical row. However, the 1st query takes almost 0 second to execute, and the 2nd one takes more than 12 seconds, on a pretty beefy machine. I had played with the target text, like placing '%' here and/or there, and observed the similar timing every time.
    So I am wondering what I should change to make the 'LIKE' operator run as fast as the '=' operator. I know CONTEXT/CATALOG index is a viable approach, but I am just trying to find out if there is a simpler alternative, such as a better use of the index t_val.
    1) Query with '=' operator
    SELECT id
    FROM T
    WHERE fid = '{999AE6E4-1ED9-459B-9BB0-45C913668C8C}'
    AND val = '3504038055275883124';
    2) Query with 'LIKE' operator
    SELECT id
    FROM T
    WHERE fid = '{999AE6E4-1ED9-459B-9BB0-45C913668C8C}'
    AND val LIKE '3504038055275883124';
    Execution Plan
    0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=1 Card=1 Bytes=99)
    1 0 TABLE ACCESS (BY INDEX ROWID) OF 'T' (Cost=1 Card=1 Bytes=99)
    2 1 INDEX (RANGE SCAN) OF 'T_VAL' (NON-UNIQUE) (Cost=4 Card=12)

    I will for sure try to change the order of the PK and see whether there will be any impact to the performance.
    In our application, val is much closer to a unique value than fid. In the example query, the execution plan showed that the index on val was indeed used in the execution of the query. That's why the 1st query took almost no time to return (our table T has more than 6 million rows).
    I was hoping the 'LIKE' operator would utilize the t_val index effectively and provide similar performance to the '=' operator. But apparently that's not the case, or needs some tricks.

  • Allow user to take survey multiple times, but do not allow the same response

    I have a requirement to allow users to take a survey multiple times, however, the answers to the survey can not be the same.
    So when a user takes the survey the first time they can take a second and a third but not have the same response.

    Thanks in advance

  • Why process chain activation is taking more time?

    Hi BW Gurus,
    I am going to activate the process chain, but it takes more time to activate the process chain . What may be the reasons ?
    Regards,
    Raju

    Hi,
    Process chain activation becomes slow due to the following reasons.
    1)Large no of entities in RSPCCHAIN Table i.e, there is  lot of process chains and very large process chains.
    2)There is a missing index for the RSPCCHAIN Table.
    Solution for this problem is  we have to create an index for the following fields of the RSPCCHAIN table.
    EVENT_GREEN
    EVENT_PGREEN
    EVENT_RED
    EVENT_PRED
    Still  if you want further clarification on this , Refer the following sap notes.
    906512---Activating process chain is very slow.

    Why download AE cs6 take so long time

    The file size is quite large.  Also the download speed is dependent on how many other users are downloading and the speed of your Internet connection.

  • Why do iPod photos take up more GB space than iPhoto photos?

    I sync all of my iPhoto photos to my iPod; the entire library is 1.1GB. Even though I have not checked "include full resolution photos", my iPod photos take up over 1.8GB. How does this make sense? It seems to me that since I am not putting on full resolution (mine are 2-3MB each, 3072x2304 jpg), that the photos on the iPod should be 320x240 (screen resolution), and those should not take up much space at all. Here is a list of the files under Photos/Thumbs on my iPod.
    F1015_1.ithmb
    F1019_1.ithmb (this file has not been modified since Jan 2007, and was created and last opened Oct 2006; it is 500.3MB, which is exactly the size of the 2 files below this one!)
    F1019_2.ithmb
    F1019_3.ithmb
    F1019_4.ithmb
    F1024_1.ithmb
    F1036_1.ithmb
    All of the rest of the files were modified and opened today, since I synced today.
    I already tried removing all of the iPod photos, then re-syncing them. Do I need to reformat my iPhoto library, or my iPod library, or something else? thanks

    I've had this problem too.
    For instance, I copied one particular albums artwork on each of it's 14 mp3's. To do this, I highlighted all of the files in iTunes and right clicked and hit Get Info. Then, I clicked and drug the file (from My Computer) and dropped it into the "Artwork" window.
    I started with 67mb of space. After I added the images to the songs, I had 37mb of space left. *The image file was only 14kb!*
    Why does it take up so much space? Has anybody posted a solution to this problem?

  • Recover after DROP USER CASCADE

    In our setup, we have one user as the owner of all the objects pertaining to the application database. I was just curious that, if this owner is DROPped, how do I recover all his objects, or what are medium/modes of recovery in this case.
    regards,
    Luckys

    Its very well possible as long as you valid backups and required archived logs.
    This tells how important is the backup and recovery policies. One need to be carefully think of all the situation before developing any backup and recovery policies.
    The finaly result from the policies is simply, minimize the recovery time and bring the database backup in acceptable time.

  • Why does some websites take a long time to load?

    so far i have found two websites that takes a very long time to load.
    and once they get there very little of the links or anything does not work
    they both work on IE but i hate that program and i would like to fix firefox but i do not know where to start

    After another restart, firefox has begun throwing errors when starting from terminal. the error reported is:
    /opt/kde/bin/skim: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
    This is printed 5 times, then gives up and firefox loads quickly after. So this appears to be an issue with skim and libpng similar to other problems being reported.
    Some research uncovered that skim is no longer supported and is part of my kdemod3 install, however until this update it was working fine under kdemod4.

  • Why needs the first reference much more time to close than all others?

    Hi all,
    I am facing a strange problem with closing an array of references.
    A few words to my environment:
    I can load dynamically VIs into a subpanel sitting on my main VI but if I unload and reload Visa I need to close my Visa properly, not just by stopping.
    Therefore I wrote a closingVI which is attached. In this VI I look for a "Stop" button and send a true by signaling.
    The problem now is that the very first reference in the "Control[]" needs around 40seconds to close, all following refs just need <1ms! By the way, the array size is just about 24 and it is independent which ref comes first.
    In addition to that the problem just occurs when the VI runs longer than 10 minutes, which doesn't makes any sense to me. 
    Do you have any suggestions?

    I don't know what you are referring to here.  You are closing all of the Control references in a single node.  Are you saying it takes that long for the Close Reference for the entire array?

  • Why does "finishing sync" take a long time

    I have an iPhone 4S running iOS 7.0.3, connected to iMac 2010 running 10.7.5.
    I have thousands of photos in iPhoto and have been syncing with my phone without a problem.  I recently bought a Canon EOS Rebel, and synced a lot of photos in JPG mode with that camera also.
    Last night, I took a dozen photos with the Canon, then imported them to iPhoto, no problem.  But when I tried to sync with my iPhone, the new photos do not show up.  I changed the sync settings to be "3 most recent events" but I don't get the event, or sometimes I have seen the event on the phone, but there are no photos in the folder.
    Also, when syncing, iTunes shows "finishing sync" for a long time, like it is waiting for something.
    I tried making an album with my new photos, and enabling syncing of that album, but that does not work either.  Any ideas?

    Did you check your security software (firewall and anti-virus)?
    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
