There is a maximun size for an instance?

Hi,
I want to know if there is a maximun size for a instance and if it's possible to increase it? Because in my process the users need to atach really big files to each instance.
Thanks in advance

Agree you can change the size of the instance in both Studio and Enterprise, but do so with caution.
Know you know this, but when you bump into the max instance size limit, you run the risk of hurting the Oracle BPM Engine's performance. This can be avoided in a couple ways. My preference would always be to go with the first option discussed below.
Separated Instance Variable
Here's your first option. There are different categories of instance variables. Long story short - consider making the large object that you're storing as an instance variable a "Separated" instance variable.
As the name implies, it will then store this variable in a separate table from the other instance variables and will not be included in the max instance size calculation. This will have the pleasant side effect of keeping your instance size smaller and your engine performance higher.
Bump the Limit in the Engine Preferences
Here's your second option. In Studio (there's a similar setting in Enterprise) you can increase the default max instance size by right mouse clicking the project's name in the Project Navigator tab and click Engine Preferences. In the Engine category, click the Advanced tab on the right and you'll see a setting for Maximum Instance Size. Don't get carried away - bumping this up too high is a sure way to hurt your engine's performance. This would serve as a fix you could apply immediately in an emergency without having to change anything in any process.
Use a Database
A third option would be to store large amounts of instance information in a separate database instead of as an instance variable. When needed, you'd just need to read it from the database only storing the primary key as the instance variable.
Sorry for the long winded answer. Know you know this, but hope it helps,
Dan

  • Hi, My places.sqlite file size is 30,720 KB have I reached the maximum size, is there even a maximum size for this. Visited links are no longer changing color.

    Hi,
    My places.sqlite file size is 30,720 KB have I reached the maximum size, is there even a maximum size for this.
    Suddenly the visited links are no longer changing font color, as I am preparing for an exam I need visited questions to change color, to keep track of questions that I have finished. But if I delete a few days of history then again,a few more visited links change color then again it stops, so it seems something is getting full and not able to accommodate any more? Why are my visited links no longer changing color after a certain number of visits? I do have a back up of the places.sqlite file. So I have tried everything from deleting the profile, uninstalling reinstalling, creating a new profile, then copy pasting places.sqlite etc, but as mentioned after a few visits, visited links no longer change color, if I delete a few days of history then again a few visits will again change color and then stop again, so what should I increase so that my visited links quota is increased, I have also tried tweaking about:config and it has had no result. Although I was not really confident that increasing brower.history_max _pages (don't remember exact name, but I am sure you get the idea) is going to help.
    Seems as though my visited links change color, quota is full and only if I delete a few days of history will I get a few more visited links to change color. Can somebody shed some light? As mentioned my places.sqlite file size is 30,720 KB so I think perhaps this has something to do with this? Would really appreciate if someone could help. Thank you.

    There is no maximum for the places.sqlite database and other SQLite database files like I wrote above.<br />
    All SQLite database file have fixed minimum sizes and if they run out of space they are automatically increased in size with a specific chunk size. For places.sqlite this is 10 MB for the minimum and for the chunk.

  • Is there a maximum program size for the AWM GUI?

    Is there a maximum program size for the AWM GUI?
    I have a program that I migrated from Oracle Exress to Oracle 9i. The program runs fine, but I get buffer errors whenever I edit it with the Analytic Workspace Manager GUI. Only my longest program has this problem.
    Has anyone seen this before? Is there a fix/workaround?
    Thank you,
    James

    This problem is solved with the 10.0.0.1.0 AWM client, which is on the 10G CD.

  • Is there a recommended (maximum) size for a catalog?

    I'm loading all my photos into PSE9 Organizer on my new MacBook Pro and was wondering if there is a recommended maximum size for a catalog? On my PC I separated my catalogs by year. My 2011 folder contains over 11,000 photos and is 71GB. Is that pushing the limits for efficiency or could I combine years?

    One catalog for all of your photos makes sense. Alternatively, as Ken said, catalogs by relatively non-overlapping subject matter areas make sense. I still see no scenario where catalogs by years makes sense, unless you can honestly say that you can remember the years of all of your 68000 photos.
    Tags and albums let you organize in ways that are nearly impossible using folders. If your daughter is named Jennifer, for example, and you assign the Jennifer tag to all photos that contain her image, then later when you want to search for pictures of Jennifer, you simply click the tag and boom, there are the photos instantaneously. You don't need to know what folder the photos are in, nor do you need to know what date the photos were taken. If you want photos of Jennifer over the years at Christmas, this is a simple search once you tag the photos, and nearly impossible using folders. The possibilites are endless. You let PSE remember where the photos are, so you don't have to. You let PSE do the searching, instead of you searching the folders.

    No, it all depends on the length of the movie or tv show. I never have seen a movie longer than 3 hours on the iTMS.

  • Is there a maximum PDF size for ios? can handle 2GB?

    I'm creating a very huge pdf file, aprox 2GB
    can it be viewer in an ipad or iphone?.
    Can it be viewer from an Android tablet?
    TnkU

    It sounds very doubtful because mobile devices are usually restricted in memory. And it will depend on each particular device. There is Adobe Reader software for both iOS and Android. Download the free software on each device and try it.
    I'd divide your PDF into smaller files.

  • Is there a maximum website size for iWeb?

    iWeb looked like the answer to my dreams. I needed to put together a website for my consulting business fast…I have another book coming out in a week or two.
    I tried on of those sites where you use their development tools on-line. Big disappointment. Too restricted and wouldn't allow me to be creative. Then I looked at spending $400 (or whatever) for DreamWeaver and go through a long learning curve learning html.
    Then I saw the ad for iWeb. Just what I needed. Mac software. Intuitive to use. A snap to learn. But I am now having problems publishing my iWeb created web-site to my domain. I am not using a .Mac account. The book already has my website listed as bobwallonline.com. Too late to change.
    My Domain size, as measured in Application support, iWeb, is now at 8.7 MB on disk. I am exceeding iWeb's limitations or is the problem to be found with ftp software I'm using to publish my site. (I'm using Web Echo and have had nothing but trouble with it since I got started.)
    So frustrating. I've got the tool that allows me to create just what I had in mind but I can't seem to publish it. Would a Macintosh support person please answer this so that I have a definitive answer as to whether or not I am exceeding iWeb's capabities? Thanks, Bob in Connecticut

    Bob, I also believe that one of the main issues hindering your work is that you have an older computer with very little memory. On another note you should enter your web host via the internet. Log on to your hosting service and delete what ever files are in there. Take your iweb site and save it to a new folder on your desktop. This will put all your files neatly in one location. then use your ftp software to connect to your host and upload your site to the server. Once uploaded make sure your index page shows and your folder. It should work fine after that. If you like to download new FTP software try Interarchy 8.2 it's the one i'm using and it's pretty fast. I got it from the Apple website on their Mac OSX link. Once there go to the downloads Link and on the side bar look for the internet utilities link.
    Hope that helps and good luck.

  • Is there a maximum viewport size for an EPUB file in iBooks?

    I have noticed that very large viewports sometimes cause iBooks to crash. Is there a maximum size allowed?
    thanks,
    Liz

    The viewport size I use is 512px wide by 768px high for my individual .xhtml pages.  For a two-page spread this would mean the viewport is actually 1024px by 768px.
    Yet I paint my original images for a Children's Read Aloud Fixed Layout ePub at 2048px wide by 1536px high and then cut the painting in half for a two page spread.  This means on the new retina display, my images will look great yet be backward compatible with the original iPad.

  • There's a maximum size for the header-I need more room

    This is a weird one for me. I am making a worksheet for my students and I'm making them in sets of four so they can work together. About 2/3rds of each page is the same, with a list of different words at the bottom. So I want to put the top 2/3rds of each page into the header, since I need to make 10 sets of these.
    But I can't. Pages won't let me make a header that goes more than about a third of the way down the page. Anything entered lower than that is cut off.
    What's the point of this restriction? Forget that—is there any way around it?
    Any help will be greatly appreciated.

    Hi Peter,
    Don't use a header. Place the fixed text into a floating text box in a Pages word processing document.
    Resize the box to fit within the document margins, and place it where you want it on the page.
    Apply Wrap to prevent 'regular' text from sliding over or under the text box.
    With the box selected, go Format > Advanced > Move Object to Section Master.
    The text box (and its text) will appear on each page until you enter a Section Break. The rest of the page will contain whatever text you enter in that area.
    Regards,
    Barry

  • Is there a maximum HDD size for this motherboard?

    I am thinking of upgrading my HDD containing my Vista operating system to one of at least 1TB in the near future and believe that I saw somewhere that some BIOSs limit the size of HDD which they will recognise.  Is this correct?
    If it is, then is there a way to partition a big HDD to overcome this problem?

    Quote from: Bas on 01-May-09, 01:20:03
    There is no limit you can reach at the moment on harddisk size, as no harddisk is big enough
    Thanks very much Bas.

  • Is there a maximum file size for Quicktime files?

    I am trying to make a Quicktime file of 40 gig size, but it keeps failing

    in case you're exporting to a fat32-formatted media, those have a 4GB-per-file limitation...
    but QT? No, no limits.

  • Is there a maximum song size for iPods?

    It took me a while to work this out, but it seems the iPod Shuffle has a limit to the length of audio files it can play.
    Due to the pause between tracks, I have encoded a few albums as one 96kbps AAC file per album, which is OK for shorter albums. With the longer ones, though, after maybe 40 minutes or so, the iPod Shuffle starts crackling and stuttering. It seems like after a certain track length or filesize, it can't keep up any more.
    Has anyone else experienced this? Does anyone know if it affects the iPod Nano or regular iPod too, or is it just due to the simplified design of the Shuffle in particular?
    512MB iPod Shuffle

    I tried that a long time ago, then took the Shuffle back to the Apple store and got it exchanged for another one. Seeing as the second one has the exact same problem, it looks like something that all iPod Shuffles have (or at least the first batches of 512MB versions made early last year).
    Maybe I should experiment a bit more. I suspect the audiobooks you mention would be much lower bitrates and mono. That would suggest it's probably a limitation due to the filesize in bytes rather than the length of the file in seconds.

  • Maximum file size for iDisk's public folder?

    I was wondering whether there is a max size for files in the idisk's public folder.
    When syncing my 68 MB zip file, the file on the iDisk shows 0MB. When uploading files externally via Safari, any file above 1 MB shows as 0MB.
    What are the restrictions...cannot find any information in the database.

    Hi Jürgen,
    Apparently there is no limit to the size. Check out the size of this file I have stored there! (;>)
