Large text with national caracters and full text index

Hello,
I have some large portion of string to index. So of these strings contains national characters so I have stored it into a NCLOB column. I would like to put a full text index of this column but I see that it is not possible for NCLOB column.
Does anybody have the problem as me? If yes, how did you proceed? Could the XMLType be a solution ?
Thanks for your help.
Kind regards,
Fred

Hi Fred,
"I do not think that I can manage all these characters with only one character set."
Sure you can. The main reason for using the NLS characterset has nothing to do with whether you can/cannot support multiple languages with your database charset. It is there primarily in case your db characterset is not some unicode/multibyte charset and you need to add support for it while maintaining your original db charset. A secondary reason is for certain performance considerations, but that is for specific application architectures and doesn't seem to be the case here. One of my apps supports virtually every language on Earth - not using the 'N''s'. I'm using AL32UTF8 - it is up to Unicode 4.0 in version 10gR2 of the db.
Choose a unicode character set for your db and you're fine unless you have some overwhelming reason why you are unable to do so. Any Text index will work for you and your problem is solved (and ctxxpath and context index will both work - just compare your requirements to the functionality provided by the index type).

What is the best software for burning a large slideshow with 500 photos and music to DVD?

What is the best software for burning a large slideshow with 500 photos and music to DVD?

Are you talking about strictly burning an already put-together slideshow or composing one and then burning it?
My all time favorite slide show maker is Photo to Movie; you can then burn it from there or get it into iMovie and/or iDVD for the "finishing" touch. My favorite burn software is Toast, although you can use iMovie, iDVD, and Finder as well.

Database link with the alias and full description in the connect string

Hi,
i have created database link with alias in tnsentry and full description
and suppose i have removed the tnsnames.ora file what will be the impact on the database link that is whether database link will work or not i am sure db link created with alias won't work and how about db link created with full description and which one you prefer
Thanks

# Parameter file initora for Database prd
### Global database name is db_name.db_domain
global_names = TRUE
db_name = prd
db_domain = world
# TNSNAMES.ORA for prd ###############################
prd.world = (DESCRIPTION = (ADDRESS = (COMMUNITY = tcp.world)
(PROTOCOL = TCP) (Host = 100.10.100.1) (Port = 1521))
(CONNECT_DATA = (SID = prd) (GLOBAL_NAME = prd.world)
(SERVER = DEDICATED)))
Our database link points from the local database test to the remote database prd. Therefore we need the global database name for prd. Ask the remote database administrator for these information or connect to prd and execute the following query on prd:
SQL> select GLOBAL_NAME from GLOBAL_NAME;
GLOBAL_NAME
prd.WORLD
CREATE DATABASE LINK prd
CONNECT TO system IDENTIFIED BY system_passwd
USING 'prd';--- alias
so the connection description will be ---select ename from [email protected]

Source for Init with data transfer and full load

Hi Experts,
1. Please tell me where the data comes when we do the
    following actions :-
    a) Init with data transfer
    b) Full load
i want to know the source of data i.e (setup table or main table or any other table)
Helpful if you can provide the data-flow.
kindly tell which is prefrable and why?
Regards,
RG

Hi.......
When you do init with data transfer it will read data from the set up table only..........but beside this it will also set the init flag..........due to this from next time any new records will go to the delta queue...........and next time when you run delta load it will pick records from delta queue...........
Now suppose data are alrady available in the BW side...........then you can run init without data transfer.......this will only set the init flag.........it will not pick any records.........
Extraction structure gets data from set up table in case of full upload ............and in case of delta load from delta queue.......

Debjani...........

Import and process larger data with SQL*Loader and Java resource

Hello,
I have a project to import data from a text file in a schedule. A lager data, with nearly 20,000 record/1 hours.
After that, we have to analysis the data, and export the results into a another database.
I research about SQL*Loader and Java resource to do these task. But I have no experiment about that.
I'm afraid of the huge data, Oracle could be slowdown or the session in Java Resource application could be timeout.
Please tell me some advice about the solution.
Thank you very much.

Gradient problems with stepping single and full colour

Hi, just wondering is anyone else is having problems on printed
jobs with the gradient having definite steps between the
different tints. We had no problems with CS3, but since updating to CS4 we
have had jobs showing this stepping problem. Has Indesign changed settings?
Any help would be appreciated I have checked all the the PDF settings as our RIP works from the PDF's to create the plates. The RIP is a Harlequin Rip.

GrahamHe wrote:
We don't actually rip the files. We are a pre-press/production department in an Agency. We do ensure that the files we deliver to the printer are 100% clean. Our problem with exporting is that if you have a gradient, as InDesign splits up large images into small pieces when writing the PDF we have seen single images that have different resolutions. We even had one file where 99% of the image was 350 dpi, and a small part 100 dpi.
It could be that CS4 has fixed these problems and am willing to try it out, but am very wary of exporting.
InDesign only splits things up when you flatten, as far as I know. If you use an unflattened format, PDF1.4 or higher, there is no flattening, so the problem may well be in HOW you are exporting. Of course, it sounds like you do ads, and I send flattened ads to publications myself because I don't trust that they know how or have the technology to handle a proper transparent PDF, but I don't distill, and I try to avoid situations that would cause problems to begin with.
Take a look at the Transparency Flattener Preset you are using when you export. I believe the default is [Medium Resolution] which has a gradient resolution of 150 ppi. If possible, save your distiller settings as a .joboptions file and use that to export the same file and compare the distilled and exported versions.

Viewing a folder as large icons with only up and down scrolling?

This is something that's been bothering me for a while and I just can't seem to find the answer.
If I open a folder, switch the view to "as Icons," and then make those icons larger, I'm forced to scroll through those icons by moving left/right and up/down. If there are a lot of files in this folder, it's quite a pain to do all that scrolling. Anyway I can change the view settings so I only have to scroll up and down?

Sort the Icons so that they fit the side to side dimension, any sort will work, by name is the obvious way.

Large HASH_SIZE with DBMS_UTILITY.GET_HASH_VALUE and performance

I need to set the hash_size to quite a large value (16777216) in order to ensure uniqueness for the sets of values I ma hashing.
The examples all use much smaller values (128K).
It seems unlikely to me, but do large values for hash_size affect performance, perhaps in the amount memory used in the PGA for the hashing fucntions.

Hi Nijmegen
I think your problem is not related to OWB, but anyway.
If you don't change data type to char, GET_HASH_VALUE function will automatically change this data type to char in your case datetime will be changed to something like '2007.12.16' (try simple function to_char). So both values are equal '16-12-2007 13:43:55' = '2007.12.16' and '16-12-2007 16:43:55' = '2007.12.16' and you will get the same hash value. Better use POWER(2,30).
example
SELECT
DBMS_UTILITY.GET_HASH_VALUE (
TO_CHAR(TO_DATE('16-12-2007 13:43:55','dd-mm-yyyy hh24:mi:ss')),
0,
POWER(2,30)) AS x1,
DBMS_UTILITY.GET_HASH_VALUE (
TO_CHAR(TO_DATE('16-12-2007 16:43:55','dd-mm-yyyy hh24:mi:ss')),
0,
POWER(2,30)) AS x2,
DBMS_UTILITY.GET_HASH_VALUE (
'16-12-2007 13:43:55',
0,
POWER(2,30)) AS x1,
DBMS_UTILITY.GET_HASH_VALUE (
'16-12-2007 16:43:55',
0,
POWER(2,30)) AS x2,
TO_CHAR(TO_DATE('16-12-2007 13:43:55','dd-mm-yyyy hh24:mi:ss'))

Safari launches with spinning ball and full fans and 100% CPU web processes

Exactly the same issue on Macbook Air and new iMac both running Safari 5.1 and Lion 10.7.3
When I open Safari it does not open a page, it just shows a spinning beach ball and shortly after the fans kick in and the activity monitor shows 1 webprocess at 99 - 100% or sometimes 2 web processes at 50/50% all coming from the User. When I inspect the process it says it's "Parent Process (Safari 450)"
When I quit safari the web processes stay at 100% and will only stop when I quit them in activity monitor.
I have reset Safari but no joy.
Firefox etc works fine.
The only update I ran was a 1Password update but they say it's not them.
Any help would be appreciated. It's driving me crazy.

Solved..... I used App Zapper to delete Flash and Safari is working fine again!

Adobe X - How to default to open with navigation bar and full screen?

Hi,
I had been using Adobe 9. But then a few weeks ago it ran into a "search" bug in which the word being searched wouldn't highlight on the page. So...I switched to Adobe X.
Here is my problem. When I open a PDF file now, it defaults to having this "Navigation Pane" open on the left (paper clip, binoculars, etc). For every document I use I have to "close" this pain (right click, select close), which then triggers this little tool on the bottom of the document to open up, which I then have to click the "Show Adobe Reader Toolbar" button to get the toolbar I need at the top of the screen. Then I need to click "fit to window length and enable scrolling."
This seems like a LOT of steps to get to where I used to be.
Any thoughts or help?
Thanks in advance,
Jason

Hi Jenn,
I appreciate your reply, and I understand the steps you suggest. I followed them. It should work....but it doesn't. Maybe this is another bug?
If anyone has any other thoughts, I would greatly appreciate it.
Thanks,
Jason

Send As and Full Controll permissions not working in OWA

I have an exchange 2013 enviroment where I work with send as and full access permisions via Active Directory groups.
I have given the group FC on a shared maibox and in outlook, the user who is member of this group can open the additional mailbox.
In owa the same user cannot open the additional mailbox, exept when I give the user directly FC on this mailbox.
How do I configure Exchange so the user can access the additional mailbox in owa, without giving him directly FC permissions.
btw In an exchange 2010 enviroment this issue is not there.

Hi,
From your description, I recommend you restart IIS by running IISReset from a command prompt and check the result. I see others have the same issue, they resolve it by running IISReset.
Here is a thread for your reference.

Why each time I try to save my day's work,version WITH mark-ups and version w/o, does it say "you have placed a large amount of text on clipboard do you want to access this? What is clipboard and how can I just save my work in its proper file?

I don't get this clipboard thing! I have created two files, one for the MS with mark-ups, and one for the unmarred version, each living in their own spot in my "house." It seems to be merging the two versions and I have to go in and re-paste and then it always says "you have placed a large amount of text on clipboard do you want to be able to access this?" and it prompts me to say no but I am afraid I'll lose my day's work so I just tap cancel. I highlight the day's revision and select "copy" to paste into the unmarked doc. before I save on the marked up or working doc. It is when I try to close that one that the clipboard issue pops up. What can you tell be about saving doc. in two places and how to NOT get it on clipboard? Thanks! I am not super computer savvy so layperson's language much appreciated!

Are you using Microsoft word? Microsoft thinks the users are idiots. They put up a lot of pointless messages that annoy & worry users. I have seen this message from Microsoft word. It's annoying.
As BDaqua points out...
When you copy information via edit > copy, command + c, edit > cut, or command +x, you place the information on the clipboard. When you paste information, edit > paste or command + v, you copy information from the clipboard to your data file.
If you edit > cut or command + x and you do not paste the information and you quite Word, you could be loosing information. Microsoft is very worried about this. When you quite Word, Microsoft checks if there is information on the clipboard & if so, Microsoft puts out this message.
You should be saving your work more than once a day. I'd save every 5 minutes. command + s does a save.

I want Firefox to not be so wide so I need to scroll back and forth with much needed larger text

I want to have large text, but narrower windows. Every time I need to make text larger for certain sites; it makes my viewing window wider so I have to scroll back and forth to read. I once had an add on to keep the window the same size in width, just with longer windows, which I don't mind. I can't remember what it was called. Therefore I can't find it to download.
Please help.

Thanks for the help, Gryllida, I've tried the zooming in/out feature, but it seems to only work on the headers or headlines on some sites; and still the reading text stayed small. I think I'll try the extension instead.
Boy, I do remember using Opera too.
My new computer came yesterday, I'm going to install Ubunbtu instead of windows. It's a barebones kit.

Searching with large text

Greetings,
We are evaluating Oracle 10g specifically for its Oracle Text functionality and are having a difficult time trying to figure out how to use large text for searching.
Specifically, we have a table containing large, full-text descriptions that we wish to find using smaller abstracts. Our full-text may be anywhere from ten thousand to a hundred thousand characters in length. Our abstracts tend to be much smaller; in the five hundred character range.
We wish to use these smaller, five hundred character abstracts to locate documents that may be related based solely upon common keywords. We will eventually get into concept matching, but for now we simply wish to find document matches based upon keywords. This query is quite similar to ORing every term in the abstract and performing a CONTAINS query, but should hopefully be less clunky.
SQL Server allows us to do this quite simply by performing a freetext search. We plug our abstract into the search algorithm and receive a listing of documents that it deemed to be similar.
Does Oracle Text provide a similar functionality and, if so, can someone point me in the right direction?
Many thanks,
Kirk

We are currently using a tool mandated by our client to cluster documents and perform concept (theme) based searching. This tool does not, however, perform keyword searching. We are looking to supplement its results with keyword search results from, say, Oracle Text or SQL Server (or Google or any of 100 other keyword search capable tools on the market).
We already have a working prototype that uses SQL Server. Using fulltext keyword matching, it accepts an abstract and returns to us all of the documents that mostly closely match. We would like to also perform this test in Oracle Text, however, we are unable to figure out how to make Oracle accept a large text for searching without significant reformatting.
For example, say my text is "Four score and seven years ago". In SQL Server, I am able to pass this in, as is, and it will return to me the Gettysburg Address as its highest ranking match.
With Oracle Text, I was able to produce similar results, but I had to reformat the query string to "$Four$|score$|and$|seven$|years$|ago". I am looking for a way to pass in "Four score and seven years ago" without having to perform any gyrations on the text.
Thanks,
Kirk

Full text index searching in large document sets

I have been placed in charge of a digital PDF document library for a small biotech company. The library consists of about 1000 100-300 page .pdf documents which have been scanned and OCRed. In order to facilitate the full text searching of the documents a PDX catalog has been created. In theory, the PDX catalog would seem to be an excellent means of quickly accessing the data, but due the sheer volume of text that is contained in the documents this does not seem to be the case.
Any given search may take hours to complete and many computers in the department have been known to lock up due to the load of running a search. Obviously, this has made using the PDX search more of a hassle than it is worth.
I do not know exactly how the index searches work, but from what I gather they somehow search within each document in turn and return to you all the instances in all the documents that contain a certain term. If this is the case, than it would make sense that the searches would take a long time because the search would have to search each of the 1000 documents in sequence.
The thing is: we really do not need to know the context and placement of every instance that a word appears in a document. All we need to know is IF it appears, and perhaps how many times. Is there a way to make an index that will simply give us this information without having to search the actual document?
Heres an example of what I am trying to achieve:
Note: I know almost nothing about full text indexes so please forgive me if any of this sounds insane
Lets say we have a document called "word count.pdf" which contained the following text:
"blah blah yadda yadda text Recombinant human insulin more text still texting and so on"
And another called "word count 2.pdf" with the following text
"Recombinant human insulin and la la la dee do"
The indexes for these files could be condensed and stored like this:
"Word count.pdf"
Blah 2
yadda 2
recombinant 1
human 1
insulin 1
text 2
texting 1
and 1
so 1
on 1
"Word count 2.pdf"
recombinant 1
human 1
insulin 1
and 1
la 3
dee 1
do 1
In this example, if we were to run a search on "text" the index would return "word count.pdf, 3 instances (2 of text and 1 of texting" whereas if we were to search for "recombinant" it would return both "word count.pdf, 1 instance" and "word count 2.pdf, 1 instance".
This way, I could quickly weed out all documents that do not have the word that I am looking for and get an idea about which documents should be searched more in depth without scanning every single instance of the term in every document.
Is there any way to accomplish something similar to this using acrobat? (Or anything else, for that matter)
My specifications: (similar to specs of all computers searching the pdx):
Windows XP,
intel celeron CPU 2.6GHz, 1G of ram
Adobe Acrobat 8 Professional

Look at dTSearch. We used the publisher version for a CD with large files sets (with hundreds of pages per file/thousands of PDF pages of multicolumn index data - text heavy), and it does a great job. The desktop version would provide the type of searching you are looking for. Indexing is also very fast. Our customer complained, like yourself, about the speed of searches in Acrobat 6 and higher - most of the delay is due to the population of the results window.
