Oracle Text suitability for my project

Hi,
i am building an application that stores web content. The content could be anything you see on the web - html, javascript, pdfs, binary files and xml.
I've had a look at Oracle Text and it seems ok to find keywords but are needs are a bit different:
1. Find whole chunks of text eg javascript code blocks, paragraphs of text
2. Find recurring bytes in binary files.
Can Oracle Text do this?
Thanks

1. Find whole chunks of text eg javascript code
blocks, paragraphs of text
2. Find recurring bytes in binary files.Can you please expand a bit on this? Maybe give an example to illustrate your requirement.

Oracle Text Search for UCM on Standard One

I'm curious if OracleTextSearch Component for UCM would work with 11g Standard One (or if there are any limitations running UCM with Standard One). Any experiences out there - as this would be for primarily smaller instances?

As far as I can tell, that component exposes some of the functionality of Oracle Text 11g.
Looking at this feature comparison set here:
http://www.oracle.com/database/product_editions.html
It looks like the Standard Edition includes Oracle Text.
Having said that, i've used Oracle Database 11g Standard as a development platform for a while. I would think that would be just fine, considering the small amount of information supplied about your particular implemetnation, metrics baselines, etc.

Pls revert me,thanks a lot!
New Groupie for Oracle APP.

I'm running it in production, and have run into some issues where I recommended to management to just spring the few hundred bucks for SE.
The basic problem is it has the bugs of a first release. For my system, a few have been minor, but there has been an extreme growth of the sysaux tablespace. For me, it wound up being simplest to just make a gold backup and restore that whenever the problem manifests, but I can only do that because I can reload all new data. I have to make more gold when DDL changes.
I think the lack of bugfixes turns XE from a great idea to a bad one. It's supposed to be appropriate for environments with no DBA, but that is just plain wrong.
YMMV.

Is Air suitable for this project?

Hi,
I've been asked to create a desktop application for a website speed test widget, would Air be suitable for this? The thing I am concerned about is that the runtime has to be downloaded before Air applications can run, is there an auto-installer that can be packaged with the file so the user doesn't have to download the runtime package separately?
Thanks,
eb_dev

As long as the web sites in question use only HTML, JavaScript, Flash, or PDF, then you should be able to create such an app.
You can use a "badge" to install both an AIR application and AIR, if needed, from a web page. Adobe doesn't provide a separate installer that installs both, but you can create your own, as long as you sign up for the AIR runtime redistribution agreement: http://www.adobe.com/products/air/runtime_distribution1.html. (You will receive documentation and some helpful tools when you are approved for the program.)

How to use oracle fusion middleware for integration project ?

hi all,
in my projects, customer (a bank) already has many applications (bankend & frontend) that are complicatedly connected. I intend to use oracle fusion middleware to integrate all applications and make adding new applications in the future easier. I have worked through documents in the oracle website but I still have no idea how to use oracle fusion middleware to address the requirement, besides oracle fusion middleware includes a bundle of applications I don't know which one I would need.
could anyone give me some instructions ? appreciate your help.
thank very much,

Oracle text search for BLOB help

Hi folks,
I am trying to build app for searching BLOB content(mainly ppts and pdfs)
I am able to upload and download files as well but the below search code give me error.
Can you please review and advise what I am doing wrong or what needs to be fixed in the code.(ideally the code should give me the list of docs that have the search string I enter)
Code :
declare
v_name varchar2(100);
v_doc blob ;
begin
select name, doc into v_name,v_doc
from BLOB_TABLE
where CONTAINS(doc,:P2_GO)>0;
end;
Error I get when I run the code is :
ORA-01422: exact fetch returns more than requested number of rows

should give list of docs??? Read this http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/selectinto_statement.htm
SELECT...INTO can only return one single row, thats why you will get an ORA-01422
declare
v_name varchar2(100);
v_doc blob ;

What are you trying to do with above code as I don't see any logic that uses those variables? and is this code inside an apex component?

Need to know if Oracle will work for this project

I am looking for an appropriate software application that is free and can handle the job I need to get done. I need an application that will allow me to save email messages from a forum and cross reference them by email address, topic, keywords, date etc. in order to make a easily searchable database out of the information contained within the emails.
I know next to nothing about database software so am asking if the free version of Oracle will do what I need.
Sandy

Hello Sandy, and welcome to the OTN forums!
I need an application that will allow me to save email messages from a forum and cross reference them by email address, topic, keywords, date etc. in order to make a easily searchable database out of the information contained within the emails.
I know next to nothing about database software so am asking if the free version of Oracle will do what I need.Well, XE doesn't "ship" with taht kind of applicaiton, nor do I know sample applications that do exactly would you are searching for. But XE could be a platform. This depends on how much of the application you expect to implement yourself and how many users would use that application. The "free version" of Oracle Database (Express Edition aka XE) is limited in various ways, e.g. to use just one CPU at a time and not more than one GB memory in total, as well as (of release 11.2) 11 GB for user data on your disk. So, if this is application shall be used by only a few users and you'll find 11 GB enough for your database, XE can be sufficient. See the [url http://docs.oracle.com/cd/E17781_01/license.112/e18068/toc.htm]Licensing Information for all details.
XE also comes with a lot of PL/SQL APIs that can do a lot of things for you, even SMTP support for fetching emails is possible.
As for the front end, you have Oracle Application Express (APEX) in XE that will allow you to build the frontend for your database very easy. You'll find a few example applications and a lot of tutorials on APEX that can help you with that job.
If you have your favorite development framework already, you can surely use XE as database backend for lots of frameworks, e.g. using JDBC or .NET providers.

How is Aperture or iPhoto suitable for my slide scanning project?

Hi!
I am confused as to what program to use for my project; I have many hundreds of slides/films/photos I will be scanning but I will make this as simple as possible. Let's say this is what I have done so far:
1) Scan slides from 10 Kodak carousels and save as 18MB TIFFs ~2400dpi or greater. These are numbered Tray 1 001, Tray 2 001, Tray 3 001 etc. and each tray has 140 slides. However, please note that these slides are mixed up within and sometimes between individual trays, i.e. some are from 1960 birthday parties, 1977 hiking trip, 1968 Christmas, etc. (There is no way I will arrange them before scanning!)
2) Bring them into PSE 8 and do editing. Post editing, save as a separate JPG which is now 6 MB in size, and with the same name except of course the .jpg extension. Store the TIFFs on external HD.
3) This is where I am stuck! I need to completely rearrange these JPG-images and give them more descriptive names. If I do not use Aperture or iPhoto, I would probably make 10 separate folders, drag JPGs into these folders and their subfolders, relabel the JPGs, do more shuffling, and be done....but my arm would fall off by then.
Can you give me an idea of how my workflow would go if instead of step 3, I brought these mixed-up JPGs into Aperture for my rearranging (and probably more editing) using keywords/projects/folders etc?
I do have one more pressing question. If I go the Aperture route and I have finished my project and I want to take my Aperture library to a computer that does not have Aperture or iPhoto (say a PC) or bring them into Lightroom or some other program, what will happen to my file structure? Will a JPG I have labeled '1968 Christmas 001' still be in its folder I have labeled 'Christmas'? Will my Masters remain labeled 'Tray 1 001 as they were when I first imported?
I use iPhoto but have not imported any of these scanned slides because I just don't think iPhoto is suitable for my project. I am also curious if Lightroom might be a viable alternative and once I have everything ordered and labeled to my satisfaction, I could then bring them into an 'iProgram' for the fun stuff.
Thanks and if anybody has any suggestions to better my workflow, feel free to comment!

If at a later time I choose to leave Aperture, can I get my files out in some semblance of the structure I have established?
Yes, Depending on the setting you give to Aperture it might not even be necessary to get them 'out', because they are not even 'in'. This is the widely discussed 'referenced' vs 'managed' topic. BTW, this only holds for the original files. Edited version always need to be 'taken out'.
If I go through the trouble of sorting all my photos and creating projects, albums, etc, when I export will it create a file structure similar to it?
Yes, you could tell Aperture to create a file structure similar to your internal structure.
And will it export the various versions, in addition to the original files when i export it?
Yes, but not simultaneously, by hitting one button. Exporting originals (called masters in Aperture terminology) and versions are two different buttons to push.
I understand from reading other forums that with iPhoto the library structure will be lost because it is an SQL database but I'm trying to figure that out with Aperture.
This is not entirely true. Both programs will export keywords, GPS data etc. etc. iPhoto will not create a specific file structure on export, but Aperture can do that. Some people are frightened that the files are stored inside a library, where they cannot physically see the files, but both programs have the ability to store outside a library package and in a location where you can physically see your files. Of course when you stop using these programs you will loose the database benefit (i.e. fast searching on various forms of metadata and using those data for sorting), since you'll now be managing your photos again with an ordinary file manager.

Performance issues and options to reduce load with Oracle text implementation

Hi Experts,
My database on Oracle 11.2.0.2 on Linux. We have Oracle Text implemented for fuzzy search. Our oracle text indexes are defined as sync on commit as we can not afford to have stale data. Now our application does literally thousands of inserts/updates/deletes to those columns where we have these Oracle text indexes defined. As a result, we are seeing a lot of performance impact due to the oracle text sync routines being called on each commit. We are doing the index optimization every night (full optimization every night at 3 am). The oracle text index related internal operations are showing up as top sql in our AWR report and there are concerns that it is causing lot of load on the DB. Since we do the full index optimization only once at night, I am thinking should I change that , and if I do so, will it help us?
For example here are some data from my one day's AWR report:
Elapsed Time (s)
Executions
Elapsed Time per Exec (s)
%Total
%CPU
%IO

8.81
8.39
27.79
02yb6k216ntqf
begin ctxsys.syncrn(:idxownid,...
Full Text of above top sql:
ddr8uck5s5kp3
begin ctxsys.drvdml.com_sync_index(:idxname, :idxmem, :partname);
end
02yb6k216ntqf
begin ctxsys.syncrn(:idxownid, :idxoname, :idxid, :ixpid, :rtabnm, :flg); end;
Now if I do the full index optimization more often and not just once at night 3 PM, will that mean, the load on DB due to sync on commit will decrease? If yes how often should I optimized and doesn't the optimization itself lead to some load? Can someone suggest?
Thanks,
OrauserN

Pre-tagging text files for FrameMaker 11

In older versions of FrameMaker I used to be able to pre-tag a text/data file using @tag name=[paratext] at the beginning of a paragraph so that when the file was imported to a FrameMaker template, the specified tag would be applied automatically and I didn't have to apply the tags manually. This doesn't seem to work any more, but I can't believe this feature is no longer available. How do I do the same thing for FrameMaker 11 please?

The include statement at the top of an MML file is optional, but handy if you do a lot of MML work and always use the same styles. For occasional work or document with a "novelty" style-set, it's enough to put a <!DefineTag> slug at the top of the MML source for each style. Just remember to start the file with <MML> – the FM import scrutinises the file rather than relying on the extension – and to save it as ANSII. Oh, and I've noticed/learnt that if you don't leave a blank line between each tagged paragraph in the input, FM adds a space at the end of the paragraph. (showing my age – I've been sternly warned against increasing file-size with this sort of thing)
I use MML a lot, for cleaning up – erm – enthusiastically formatted or completely unformatted .doc files, and apart from missing support for tables I find it a valuable blade on my FM Swiss Army knife <g> Minimal work with a text editor can convert an MML file into tagged text suitable for InDesign. Haven't had the occasion to experiment with IDD to MML, but who knows … that might work too.
Just for completeness, a small example:
<MML>
<!DefineTag :h2>
<!DefineTag :p>
<!DefineTag :ul>
<!DefineTag :ul_2>
<:h2>System requirements – disk space
<:p>A minimum of 1Gb free disk space is recommended.
<:ul>around 250 MB for Java
<:ul>around 12 MB for a fresh Tomcat Server installation
<:ul>around 23 MB for KEY LOADING SERVER files
<:ul>additional space for
<:ul_2>Tomcat Server working files
<:ul_2>KEY LOADING reports
<:ul_2>log files (space depends on the trace level and clean up policies adopted)

Is Oracle Text the right solution for this need of a specific search!

Hi ,
We are on Oracle 11.2.0.2 on Solaris 10. We have the need to be able to do search on data that are having diacritical marks and we should be able to do the serach ignoring this diacritical marks. That is the requirement. Now I got to hear that Oracle Text has a preference called BASIC_LEXER which can bypass the diacritical marks and so solely due to this feature I implemented Oracle Text and just for this diacritical search and no other need.
I mean I set up preference like this:
ctxsys.ctx_ddl.create_preference ('cust_lexer', 'BASIC_LEXER');
ctxsys.ctx_ddl.set_attribute ('cust_lexer', 'base_letter', 'YES'); -- removes diacritics
With this I set up like this:
CREATE TABLE TEXT_TEST
NAME VARCHAR2(255 BYTE)
--created Oracle Text index
CREATE INDEX TEXT_TEST_IDX1 ON TEXT_TEST
(NAME)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('LEXER cust_lexer WORDLIST cust_wl SYNC (ON COMMIT)');

PAUL HERNANDEZMy entire need was only to be able to do a search that bypasses diacritical characters. To implement Oracle Text for that reason, I am wondering if that was the right choice! More so when I am now finding that the functionality of LIKE is not available in Oracle Text - the Oracle text search are based on tokens or words and they are different from output of the LIKE operator. So may be should I have just used a simple function like below and used that for my purpose instead of using Oracle Text:
This function (remove_dia) just removes the diacritical characters and may be for my need this is all that is needed. Can someone help to review that given my need I am better of not using Oracle Text? I need to continue using the functionality of Like operator and also need to bypass diacritical characters so the simple function that I have meets my need whereas Oracle Text causes a change in behaviour of search queries.
Thanks,
OrauserN

If all you need is LIKE functionality and you do not need any of the complex search capabilities of Oracle Text, then I would not use Oracle Text. I would create a function-based index on your name column that uses your function that removes the diacritical marks, so that your searches will be faster. Please see the demonstration below.

Justification for Using Oracle Text

Hello,
Can someone give me good cause (justification) for utilizing Oracle Text over other tools out there that are not tied directly to Oracle?
Apparently it is possible to identify metadata within text and do keyfield and keyword searches this way with other tools, but I question the accuracy, speed, or value in terms of data relationships with this approach. I feel the relationships belong in the database along with the indexes but can't convince anyone of this.
Has anyone experience working with Oracle Text where relationships help to drive the search and can give me good cause to this approach?
thanks

Hi,
Justification depends on your use. For starters:
1) It is included in both standard and enterprise editions of the db at no added charge
2) Uses SQL to query and maintain
3) Includes a number of built-ins for maintenance and optimization
4) It has 4 different index types for various uses
5) It can index any data type
6) UltraSearch is included in both standard and enterprise editions of the db at no additional charge (this is a crawler built on Oracle Text).
As for the integration - it is optimized for Oracle. If you were to build a standalone indexing solution you would probably design it a bit different, but Oracle Text takes into account the optimizer and database structure.
It has other features (same as some of the other tools) like a knowledge base, classification, clustering, theme extraction, language-specific features, ability to index documents in and out of the database, stopwords, stemming, wildcard, progressive relaxation, and the list goes on.
I guess my question would be, what is the reason for NOT using it? That might give me a better line on the reasoning so that I can respond with something a bit more specific.

Justification for using Oracle Text vs Other Search Tools

Hello,
Can someone give me good cause (justification) for utilizing Oracle Text over other tools out there that are not tied directly to Oracle?
Apparently it is possible to identify metadata within text and do keyfield and keyword searches this way with other tools, but I question the accuracy, speed, or value in terms of data relationships with this approach. I feel the relationships belong in the database along with the indexes but can't convince anyone of this.
Has anyone experience working with Oracle Text where relationships help to drive the search and can give me good cause to this approach?
thanks

Tools like Autonomy have fantastic searching functions, far in excess of what we get with Text. What they aren't very good at is the database side of things. So if your prime concern is to be able to search free text documents on your file system using a baroque range of filters then Text is not the right choice. But if you want to join the outcomes of free text searches with structured data in database tables or if the text you want to search is stored in database tables then using Oracle's built-in functionality is the better approach.
From your post I'm not sure which scenario fits your situation more closely.
Cheers, APC
