Is there a maximum length for a custom expression?

Is there a documented maximum length of a custom expression in a sync rule? I have been unable to find one and as of yet, have not hit one. But for curiosity's sake, I was wondering if there is a limit?
Thanks

Hello FIM-EN,
Custom Expression of Synchronization rules are saved to two attributes: Initial Flow and Persistent Flow.
Both are "Indexed string", so theoretically, the length is unlimited.

Sylvain

Maximum length for an XML schema

Hi everybody,
Is there a limit on the maximum length for an XML schema? I am trying to register an XML schema using dbms_xmlschema.registerSchema(). The schema registration process seems to go fine when the length of the schema is short. But the registration process always hangs when I increase the XML schema with additional types/elements. Is there a limit on the maximum length of the XML schema with regards to registering it to Oracle?
Thanks!

Hi Erhan,
Let's say I have a really big XML schema in file "schemaA.xsd", like so:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleA="http://abc.com/schemaA" targetNamespace="http://abc.com/schemaA">
<xsd:element name="Employee">
<xsd:sequence>
<xsd:element name="Address" type="sampleA:AddressType"/>
<xsd:element name="Contact" type="sampleA:ContactInfoType"/>
</xsd:element>
<xsd:complexType name="AddressType">......</xsd:complexType>
<xsd:complexType name="ContactInfoType">....</xsd:complexType>
</xsd:schema>
I can separate this schema into multiple smaller schemas (<32KB) by using the proper imports:
In file "sampleA.xsd":
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleB="http://abc.com/schemaB"
xmlns:sampleA="http://abc.com/schemaA" targetNamespace="http://abc.com/schemaA">
<xsd:import namespace="http://abc.com/schemaB" schemaLocation="schemaB.xsd"/>
<xsd:element name="Employee">
<xsd:sequence>
<xsd:element name="Address" type="sampleB:AddressType"/>
<xsd:element name="Contact" type="sampleB:ContactInfoType"/>
</xsd:element>
</xsd:schema>
And in file "sampleB.xsd", I might have something like this:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleB="http://abc.com/schemaB" targetNamespace="http://abc.com/schemaB">
<xsd:complexType name="AddressType">......</xsd:complexType>
<xsd:complexType name="ContactInfoType">....</xsd:complexType>
</xsd:schema>
So, you see how I have separated that one really big XML schema in file "schemaA.xsd" into two XML schema files: "schemaA.xsd" and "schemaB.xsd". Also, I have added <import> tags in schemaA.xsd to refer to elements, complext types, etc. defined in schemaB.xsd. So long as these schema files are < 32KB, I can register them (using dbms_xmlschema.registerSchema()) without any problems into Oracle.
Let me know if what I said above is not too clear. Hope you find your solution soon!
Thanks!

Is there a maximum size for photos used in a slideshow? I cannot anymore put my slideshow into a wmv

Is there a maximum size for photos imported in a slideshow ? I cannot anymore put my slide show into a wmv file.

About CLOB size, it's 4Go not 4000 characters - VARCHAR2 supports up to 4000 bytes. Pay attention also to unicode encoding!
Are you using CFQUERYPARAM to insert into the CLOB fields ?
<CFQUERYPARAM CFSQLTYPE="CF_SQL_CLOB" VALUE=" ">
use the Firebug extension (https://addons.mozilla.org/en-US/firefox/addon/1843) in Firefox3 and do some network monitoring: let me know what you're seeing there.
Hope it will help...

Is there a maximum size for iTunes library

Is there a maximum size for the iTunes libary for windows 7?

Not as far as I know.
My Music Library has 17080 songs (108.38 GB) in it, plus films, Podcasts and a few iTunes U programmes, and I am aware of others using this forum who have larger libraries than I do.

Safari/WebKit - Is there a max length for URL?search_string

Is there a max length for search strings in URLs in Safari or WebKit?
e.g.

Absolutely everything in computing has limits. Whether you are reached one is harder to say.
Are you getting it on the prepareStatement() or the executeUpdate()?
If the former then I would suspect a length limit (presuming absolutely no chance of a syntax error.) If the latter then it might or might not be.

Maximum length of a regular expression

Hi,
I'm making a program for decoding traffic measurement data in text files. It is based upon regular expressions. Some of the patterns are very big. The biggest pattern is 22390 characters long. And here's were the problem is: the program just freezes when it needs to match a string with that huge pattern. Another of my longer patterns is 17634 characters long and that matches strings without any problem!
Now what does this mean?
Is there a maximum length on regular expressions and do I succeed it with my 22390 characters long pattern?
I don't find anything on the internet about a maximum length on regular expressions.
Somebody, please help!
Kind regards, Sweepee.

I understand that this topic sounds funny to some people :-), but I didn't type the pattern by my self. I use an XML file to describe a text file. In that XML file you define groups of fields within the file with measurement data. Look to this example:
<block name="data record">
<date length="8">date</date>
<time length="5">time</time>
<integer length="8">location_area_code_target_cell</integer>
<integer length="8">location_area_code_origin_cell</integer>
</block>
This fragment of XML describes a data record in the text file. With the definition of those types within a block, a pattern is generated for that block. The example above is a small data record. The bigger a data record gets, the bigger the pattern becomes. I have one measurement file where a data record contains 386 fields, which results in a pattern of 20000+ characters. This is an exception from the other files, which contain much smaller data records. In the other types of text files decoding works great with these generated patterns, but with this one text file with large data records en a large pattern it fails somehow and I still don't know how it comes.

Is there a maximum size for an internal hard disk ?

I just bought an 2.5" 160 Gb HD to replace my internal 120 Gb. Presently I only tried to mount it as an external disk, but it is recognized as a 128 Gb disk, not a 160 Gb. As it is a pain to change the internal HD, I would like to be sure the disk will be recognized as a 160 Gb before. I called Apple hot line, but they have no information, for them the maximum capacity for a Powerbook G4 12" is 80 Gb as it was never offered a larger size, but already I have a 120 Gb that I mounted myself perfectly working.
Is there a software / firmware limitation of the addressable size of a hard disk on a PowerBook G4 12" ???

I have called Apple several times, I have talked to the Apple Store in KC. Same answer...well it comes in 40-60-80 configs. Not a good answer.
The 12 inch powerbook G4 supports ATA-100 (100Mb/sec) interface. The specs on the Hitachi HD refer to ATA-6, which refers to the higher speed transfer rate of UDMA6.
As I understand the ATA (AT Attachment),PATA (Parrallel ATA), IDE (Integrated Drive Electronics) and UDMA (Ultra Direct Memory Access) are basically used interchangeably to describe the interface (see wikopedia for detail difference of implementation of specs).
Since the Mac OS supports terabystes of HD data, the OS is not a limitation. The limitation is in the motherboard interface and controller for ATA (ATA-100)
The ATA specification is 28-bit addressing with a maximum capacity to address of 137gb - 128gb formated. It is calculated as follows. A bit is either on or off meaning it is binary - or in mathmatical terms base of 2.
2 to the 28th power = 268,435,456 disk sectors to address.
Each sector has blocks of 512 bytes.
268,435,456 * 512 = 137,438,953,472 or 137GB
Once formated the drive capacity for data is 128GB.
This is the same issue as the W98 PCs. An indication Apple is way behind in technology for HD interface and controllers. Very sad!
Now the part I do not understand ATA-6 introduced 48 bit addressing, increasing the limit to 128 PiB (or 144 petabytes). This is much larger than 128GB standard ATA. My assumption here is the Hitachi HD supports ATA-6 however Apple does not support more than standard ATA on the motherboard HD interface and controller. The G4 HD controller I assume does not support Ultra DMA mode 5 compliant (UDMA5). This would mean it does not support the 80-connector cables, only the older 40-connector cables.
Does anyone know if this powerbook supports ATA-100,UDMA5, 80-connector cables?

Variable length field exceeds maximum length for VARRAW in SQLLOADER

Hi All,
I am trying to load some signature ascii data from load file. so i wrote the code like below in my controal file to load that to database. For SIGN_IMAGE in oracle db it was mentioned as RAW(2000). The below is worked fine when i tried in window and oracle 8i environment.
SIG_TYPE POSITION(23:23) CHAR,
SIGN_IMAGE POSITION(24:1977) VARRAW(2000)
NULLIF SIGN_IMAGE=BLANKS,
SIGN_IMAGE1 POSITION(1978:3930) VARRAW(2000)
NULLIF SIGN_IMAGE1=BLANKS
But when i ported the same thing to solaris and oracle 10g environment. The below code is giving error when SQL Loder loading.
The error is like : Variable length field exceeds maximum length.
But here i am giving a lenght of 1954 only with including 2 bytes length of the string.
Could any one tell me what is exactly the problem? i am not able sort out the issue.
Thanks,
Shashi

You should probably move this question to the General Database Discussions. This forum is for Oracle Forms not SQL:*Loader.

Is there a maximum size for Keynote files

I want to make sure my Keynote files are functioning well. Is there a maximum size, under which they function best? (either a number of slides, or MB/memory).
I've created the Keynote files on my iPad2, then uploaded them to my iMac desktop, used the "Reduce File Size" option on desktop Keynote, saved, then downloaded onto my iPhone4, and I'm "projecting" the files onto an Apple TV 2.
Thanks!

There's a mathematical limit due to the architecture of PDF object references but it's way beyond anything you could create in practice. Because the Acrobat Family are 32-bit applications you'll find there are performance issues if the file count gets too high - exactly when that becomes a problem depends on both the files and the hardware opening them, but given an XLSX file isn't displayed within the Portfolio (other than as an icon) it'll be less of an issue then if the files were PDFs, videos, etc.

Maximum length for Chart of Accounts

hi experts,
In chart of accounts max length is 10. generally all are taken 6, if we take any other number other than 6 how is effect and how it works can you explain clerly ? pls explain effects wit all, like 1234578910
Edited by: Lakshmipathi on Jan 4, 2012 7:02 PM
Please use the subject effectively

Hi,
You can take any numbers considering that the number would be sufficient to accomodate the requirement of the company; even 3,4,5. You can even include alphabets in that. There is no hard rule that it should be 6, but the maximum is 10. Generally companies choose from 6-8; and for consolidated/group account even 10.
Please let us know if you need any further details.
Warm regards,

Is there a maximum size for a Preference created via scripting?

Hello
I've developed a script that saves some information to Preferences file when closing AE. A user had this error:
"Unable to execute script at line 1. After Effects error: Preference [Settings_colorLibrary] 'saved_library' is 2732 bytes, max allowed is 1999 bytes."
Some testing has confirmed this error, as info written to Preferences gets bigger. My question is: Is there a limit to the information I can write to Preferences file? Error message said 2 KB, which is quite low. I had the same problem using bith Mac and Win.
Thanks.

Well I guess the error message is pretty self-explanatory: I think I remember that during the CS7 beta they said they had changed the way preferences work which makes sense given the fact that CC can now import preferences for another account.
Given this post I guess the issue is in CC only: http://aescripts.com/forums/discussion/comment/2120#Comment_2120
So I guess you'll have to maybe simply split the data into several preferences items: you could save the swatches by batches of 20 and loop through the preferences items to load them all.

How to set maximum length for TextEdit

Hi all,
I have a TextEdit UI element in my webdynpro page and I want to set the maximum number of characters that can be entered in this TextEdit. How can I do this?
Thanks,
Satyajit.

Hi Arun,
thanks for the reply. But I also want to use the same scenario for an Inputfield. Now I used the same method here and when viewed in the browser, the entire InputField has been stretched. How can I keep the view of the InputField as default but still have a restriction on the number of characters that can be entered in this InputField? It works for TextEdit.
Thanks,
Satyajit.
