Limit the size of entry for Base64InputStream.decode?

Hello everyone, I am working with the V4.5 target system and written an application that downloads data encoded in Base64 in an XML file. However, on files, I throw an IOException when trying to decode the byte data. I checked that I am indeed pointing to the correct data to Base64. Since the data is too large for a string, I use the decode method, which accepts the byte [], offset, length settings. the byte [] array is size of 301304 bytes (294 K). If it is too big is there another method to convert this?

Yes, I hate it when I find myself chasing bugs in the diagnostic code.

I have confirmed that there is indeed a large arrays of bytes decoding problem with Base64InputStream.decode. My guess is that the static method decode methods use some fixed internal buffer to perform their work. The solution is to read the data byte by byte. Instead of:

bDecodedFile = Base64InputStream.decode(m_RawData, iFileStart, iLen);

Use this:

ByteArrayInputStream bis = new ByteArrayInputStream(m_RawData, iFileStart, iLen);Base64InputStream b64 = new Base64InputStream(bis);ByteArrayOutputStream bos = new ByteArrayOutputStream();byte[] buff = new byte[1024]; // faster than byte-at-a-timefor (int len = b64.read(buff); len != -1; len = b64.read(buff)) {    bos.write(buff, 0, len);}bDecodedFile = bos.toByteArray();

That should get around the limit of 64K that you discovered.

RIM should really document this.

  • limit the size on the column heading in the report SQL auery

    Hello

    I returned a SQL query in the report where my column labels are also dynamically. Apparently, the size of this label is limited? Why?
    We tried to get the maximum and it seems that it is limited to 32 characters?

    Y at - it a solution because the meaning of the column in my app is really more important and must be displayed entirely

    Thank you

    Erwin

    Erwin,

    APEX does not limit the size of the headers of column (at least not at only 32 characters). AFAIK a limitation exists only if you use a Type of "Column names" or "column names (InitCap)." Then you click on the limitation of the Oracle DB as an identifier of Oracle, for example name or alias of the column referenced in your SQL query, may not exceed 30 characters long. To work around use a Type of "Custom" or "PL/SQL". "PL/SQL", you can dynamically set the report headings with a function that returns the headers as a string of delimited colon. You call the function like this:

    return get_my_report_headers(<input parameters>)

  • Limit the size of the File Upload/accessory

    Hi people.

    I'm trying to create a problem/bug of my request tracker item.

    All work including attach parts supporting the question and e-mail questions and updates to users with attachments to e-mail to support.

    What I am struggling with limit the size of the file that users can fix a problem (and therefore attach to emails).

    I tried to implement a validation like this...
    if dbms_lob.getlength(:P203_DOCUMENT) > 3 then
       return 'Supporting document too large ('||dbms_lob.getlength(:P203_DOCUMENT)||').';
    else
       return null;
    end if;
    I want to limit the size of the file to circa 1or2 Mb. What I found is that I dbms_lob.getlength(:P203_DOCUMENT) wildly different results to try to download files from the same sizes. for example, a test of 1105 KB file gives a performance of 57 and a file 2236 KB Gets a return of 20.

    Had a scratch around the documentation, but it is not very clear.

    If I run a query like this to the database...
    select dbms_lob.getlength(DOCUMENT)
    from user_issue_tracker
    I'm starting to get better results (for example, the number of bytes in the file)

    I expected an assessment of similar values in my validation by their SUMMIT, but I don't see the return values that I expect.

    Some popular ideas/comments/experiences.

    Kind regards

    Simon Gadd

    Simon,

    if dbms_lob.getlength(:P203_DOCUMENT) > 3 then
    

    Unless I'm misunderstanding of your code, don't you passing the name file name as opposed to the BLOB real itself, which would certainly explain why you're not given the sizes you expect since this is only counting the size of the string, you pass in, for example.

    jes@TESTDB> select dbms_lob.getlength('foo') from dual;
    
    DBMS_LOB.GETLENGTH('FOO')
    -------------------------
                            3

  • How can I limit the size of a batch of e-mail for the campaign to the warming of the intellectual property?

    We were working on our campaign 'Heating IP' for our first promo and we must limit the number of emails we send per day by Eloqua. I can't understand how to do this. I looked at Eloqua along, but I had no chance.

    I found something called 'Email Batch Control' in the Setup menu, but I don't see any way to use it for, well, control and orders by e-mail.

    Any help would be greatly appreciated. Feeling a little lost...

    Thank you.

    Hi Rob,

    You can do this in the program generator, specifically e-mail stage.  What you do is click on the drop down next to the stage of e-mail, go to "change the default step action", according to the details of "frequency", you have an option to send emails all at once or spread it in batches on a certain number of hours or days.  You would like to to be.  Now, regarding the mathematics behind it, if you load 1000 contacts in your program and the value that it be sent in batches of more than 6 hours, what he does is total-contacts / # in the batch, IE; 250 emails sent every 6 hours.

    In the case of your post, you may mant to divide on a course of a few days.

  • How to limit the voltage common mode for the switch

    The user manual mentions a maximum of ±12V ground for my switch (pxi-2536) but I do not see an entry in the field on the pinout of the connector. If I have a floating supply, should I connect the ground to the chassis on the ground on the back of the PXI? Is there a better way to limit the common mode voltage?

    Thank you specify, it makes much more sense!  The best way to go about this that seems will be grounded to the negative terminal of your power supply to ground the chassis security, as I think you suggested at the beginning.  I don't know what frame you have, but you should be able to find a "Reason for connection security" section in the manual. For example, here are the 1044 chassis manual, with the present article is on page 2-4. http://www.NI.com/PDF/manuals/371360a.PDF

  • How to limit the size of virtual memory dedicated to the JDK 8?

    Hello

    I use JDK 8 on Solaris on x 64 box 11.1:

    Java $-version
    Java version "1.8.0_11".
    Java (TM) SE Runtime Environment (build 1.8.0_11 - b12)
    Java for 64-bit Server VM (build 25.11 - b03, mixed mode)

    I am running tomcat/xwiki on top of that. I set myself as a result of operating options to limit the use of memory in Java:

    CATALINA_OPTS = "" Server - d64 - Xms1024m-Xmx1024m - XX: MaxMetaspaceSize = 1024 m - XX: MaxPermSize = 196 m-Dfile.encoding = utf - 8 - Djava.awt.headless = true - XX: + UseParallelGC - XX: MaxGCPauseMillis = 100 ' "

    These params are from the same time project JDK 7 served so I left - XX: MaxPermSize here even if it is no longer supported and I just added - XX: MaxMetaspaceSize = 1024 m for JDK 8.

    My problem is that when I put server under a load to push new sound REST API to the XWiki pages, then I see RSS (in prstat) hovers around 1.5 GB, but the growing SIZE and the entire process to push pages on the server becomes slower and slower.

    The problem is that I am not able to detect any obvious memory leak using jconsole or using visual vm and the dump of the heap. They both claims that, all in all, my JDK consumes up to 2 GB of RAM. The only exception is jconsole, in his summary of the VM pane, tells me that the amount of "committed virtual memory:" occupies about 14 GB, which corresponds to the observation of the utility value of SIZE of prstat.

    I do not like the idea of JVM consumes more memory with possibility not to stop in this process, I would like to ask if there are any parameter which will allow me to set the memory hard limit can be used by any JVM?

    Any idea is appreciated here,

    Thank you!

    Karel

    Just a follow-up. It seems that this probably isn't problem with JDK se. The problem more and more memory is caused by Apache Solr, which uses the memory-mapped file access and this adds to the amount of virtual memory. It also explains why he is not counted in the amount of heap memory.

    In any case, some kind of help on this will be appreciated in either visualvm or jconsole. For example jconsole should at least add an indicator to virtual memory committed that it contains also the memory mapped files or something like that.

    Thank you!

  • Limit the size of the catalog?

    I used to organize my photos with a catalog annually.  However, I found myself constantly go back to the pictures of previous years to create slide shows or books.  So I decided to have a single large catalog containing all the photos of the year.  There are about 20 000 photos in the catalog.  I wonder if there is a limit on the number of photos in a catalog, and if there are disadvantages to have a big catalog.  Maybe there will be some problems of performance etc... ?

    In general, less catalog best.

    Big catalogs affect the performance of some things, but the size should * not * affect performance to develop the module or view photos in the library module. What can slow down the big catalogs is time to update smart collections, lib filters or whole-catalog metadata poster--things requiring a visit all the photos in the catalog. Just develop the module works with a single record (or a small set of records), and it is also effective with 1 million photos in the catalogue as per thousand. Ditto for the library module when you have a folder or a selected collection - the other records in the database are simply ignored - not anything slow down...

    If you * notice something of slowing down when it should not, as the catalogue grows, it is usually due to another problem with the catalogue growing (or it is not at all the catalog..).

  • How to limit the size of the transform tool box?

    I'm working on creating composite images, import of small picture elements that must be positioned, scale, distorted and sometimes inverted to match the lighting of the larger background image source. For example, import a picture of a car in an enlargement of the city - scape.

    Since these elements are quite low compared to the bottom layer, when I convert the layer element into a smart object, and then use the transformation tool, the bounding box is available to match the size of the large image in the background. The control points of the area of transformation, especially in Warp Mode, are often too far apart to be effective in this little piece of fine adjustment.

    Is there a technique I use to limit the processing area to cover simply the object I want to transform? Thank you.

    Rich

    It doesn't to me with a psd placed in an another psd as a smart object. What file format you place? Do you need to use the dynamic object, it does not really help if you resize the bitmap images (unless you go back from smallest to largest).
