Language Handling in Oracle 10g Database

I want to know that how language works in oracle 10g database at micro level.Actually what happen when we insert any record into database and how database handle it.
from insertion to storage and displaying any stored record...what exaclty happens?
how oracle 10g handle it?

That would be big long session.

We are getting ¿ stored into our Oracle 10g database (Microsoft fault)

We are getting ¿ stored into our Oracle 10g database that is using WE8ISO8859P1 character set.
Problem is caused by the following:
Microsoft released software (in particularly MS Word) before considering any ANSI or ISO standard (although they claimed so).
At that time of pioneering graphical interface - they were the standard. Since then things changed. Microsoft initially targeted US marked, however very soon they wanted to expanded to Europe. For that they needed to get standardized character set instead of one initially being in use. Microsoft re-mapped character set in newer applications using Windows-1252 character set which is compatible with ISO-8851-1 (we are using in our Java Web applications). That cleared obstacles to forward on European market, where extended characters are necessary (like in French, Dutch, German languages...)
What happened with the initial character codes before Microsoft agreed with ISO to standardize characters? Well - Nothing.
So what are the consequences of that?
If we are using Microsoft Word document in conjunction with one of the oldest character set (universe) the ice-age character mapping is still there. So when we "cut and paste" the content to another application, characters sets are not mapped anymore. Especially French language "is sensitive to this" The Microsoft character set in Word decimally coded 146 ( ' ) is very often used in French.
Therefore if the text is generated in MS Word using old character mapping (universe) which we do, and using method of "cutting and paste" we are mismatching character set interpreted by other, newer applications.
Initially in the MS words (apostrophe) ' had code 191; then later after implementing Windows 1252 character set being moved to code 146 in accordance to ISO. Well ISO threat character coded 191 as ¿. So if you are using MS Word universe character set, ' looks like ' but in newer applications or ISO compatible applications it looks like ¿.
Can anyone provide me with periodically cleanup routines that replace garbled characters entered by Microsoft applications into Oracle database ?
Thanks

Oracle 10g Database conflicts with HTMLDB

Hai all,
I have encountered a strange conflict when I am trying to work out with Oracle 10g database and the famous HTML DB.
It is like this:
I have a 10g DB installed and an ASP application that works on this 10g instance via "Microsoft ODBC driver for oracle" perfectly.
Now I have downloaded and installed the 10g Companion CD and installed the HTML DB 1.5 along with the mandatory Apache web server. Good!! I could scrawl through the database using the HTML DB, creating applications, forms, items and etc fancy things without any issues.
The problem that I found was:
The ASP based application that used to work initially now is erroring out saying that "TNS could not resolve service name".
I thought that the Listener might be damaged or the ASP site was damaged or the Microsoft ODBC driver files were damaged and several other vauge guessings.
I have tested the issue in several ways (reinstalled oracle, the DB, the ASP Applicaton, re-configurin listener in a variety of ways) but every time installing BLINDLY the companion CD too. Nothing seem to work.
Then I recollected that the same issue I have encountered in the past with the installation of Oracle 8i and Developer 2000, where the TNS listener configured by the former damages the one configured by the later and vice-versa.
Basing on this past reminiscence, I finally stopped installing Companion CD over the Oracle installation and carried out the DB installation and the ASP based app. And everything worked fine.
CAN anybody tell me what is going wrong with these two oracle products(Oralce 10g DB and the HTML DB+Apache)?
WHY always the installation of a CLIENT SW (Developer, HTML DB etc) damages the connection with the database via ODBC drivers?
Many Thanks in advance.
Ravi

Dera Mr. Tyler,
Thanks for your reply...I have implemented the solution that you have given for the TNS Listener conflict and everything works fine...
Here I have one more thing thats not working as I thought. do kindly help me out.
My requirement is to show the list of available storage drives (say C:, d:, e: etc on windows) available on the database server. Let me eloborate my problem well....
i have a Java App that executes a specific SQL script to create a tablespace, a user and the required db objects that my applicaiton needs.
if the Java App runs on the same machine where the oracle instance is running, the Java app pops up a list of available drives on the machine, creates a directory for the tablespace datafiles on the drive selected from the above list box, then runs the script which creates the tablespace and the rest of the things.
But if i run the Java app from another machine on the network, then my BLIND java app is popping up the drives of the local machine but NOT those from the oracle server machine and creates the folder on the local machine but not on the Oracle server and obviously the rest of the phases (tablespace creation itself) are failing as the required folder is not found on the oracle server machine.
the work arounds that i am thinking are:
a) use java ->
get the IP of the oracle server machine ->
use some java api such as java.net, java.io etc ->
create the required folder on the server machine instead of the local machihe
ISSUE: Java network programming is too tough for me(excuse me for this..i am not too good!!)
b) use some oracle sql or pl/sql api s to do the same
ISSUE: not found one!!!!
c) create a java stored procedure/function to get the list of drives of the oracle server and return as a string variable. then call this proc from the Java app once connected to the database....
ISSUE: i have created the SO-CALLEd java func. no compilation or loading errors. but there is no o/p either. but the same code when i run as a java class is showing the desired o/p. here is the code piece...can you please help me out!!!
-------Java Stored Function------
import java.io.*;
public class HDDLister
     public static String listDrives()
          String rootsList = "Available Roots: ";
          try
               File[]roots = File.listRoots();
               for (int i=0;i<roots.length;i++)
                    rootsList += roots.toString();
                    rootsList += "#";
          catch(Exception ex)
               rootsList = ex.toString();
          return rootsList;
-------Command to publish the Funciton-------
CREATE OR REPLACE FUNCTION HDDLISTER
RETURN VARCHAR2
IS
LANGUAGE JAVA
NAME 'HDDLister.listDrives() return java.lang.String';
and finally the point of the problem is, once we show the drives available on the server machine to the user and the user selects a drive, how to create a folder on the server machine???
Thousands of thanks in advance

Oracle 10g - Database does not respond to the application users

Hi all,
I am using ORACLE 10g database with 75 users connections 50 local and 20 remote users using ADSL and dial up modem. Operating system on server is
Windows 2003.
All of a sudden users making the entry get disconnected getting the error as
ORA-12516: TNS:listener could not find available handler with matching protocol stack
Other case users when using the appliaction get their PC hanged and connection
to oracle fails again. they cannot login to the application that time, the error is
ORA-04031: unable to allocate %s bytes of shared memory ("%s","%s","%s","%s")
Twice a day the users trying to login cannot access the database server.
Front end application is in VB using exe file. When the users cannot logon
to the database. I manually stop the ORACLE services(including DB console) and
then stop the listener.
This practice is going on since last two months.
Server Scenario
After Installing Oracle Standard Edition 10g.
System tablespace utilization is 98.5% which is 465 MB out of total 470 MB.
There is only one Rollback Segment named as SYSTEM.
when we install 9i 4 rollback segments as RO1, RO2, RO3, RO4 are created
by default.
Do I need to add the datafile to SYSTEM table space as its current usage is 99.15% and its auto extend is ticked on using auto extent as 10 MB. I tried adding another datafile during weekend downtime. when I resumed on saturday morning I found it did not add any datafile which I had put on thursday eveninig as system02.dbf.
Do I need to add a new datafile to the SYSTEM tablespace ?
Do I need to create new rollback segments apart from SYSTEM rollback segment ?
My current schema size 15360Mb with its usage as 9.32% (1432.25 Mb).
Please reply !!!

I had a problem of accessing Oracle 10g database homepage. After a couple of days of research and discussions with coworker we found a solution.
Here is the solution:
1. Find out your default browser.
2. Configure your default web browser to connect to the Oracle Database XE Database Home Page as stated
here:
http://download.oracle.com/docs/cd/B25329_01/doc/install.102/b25143/toc.htm#CIHHJEHF
If this does not help de-install Oracle XE and reinstall following the instruction. During re-installation find out your default browser and configure it as instructed.
I suspect when the default web browser changes the Oracle 10g XE Database Home Page stops working.
Good luck

Oracle 10g database as Resource manager and heuristic transaction decision

Hi,
I have read in documents about distributed tarnsaction that resource manager like oracle databasecthat are involved in distributed transaction can take heuristic decision(unilateral decision) and can either rollback or commit the transaction associated with itself without having confirmation from the transaction manager.
I want to know how a resource manager take this unilateral decision and can we set this as parameter either in resource manager or in application server.
Thanks in advance

Hi,
Following are some links to documents.
Handling Heuristic Completions
http://edocs.bea.com/wls/docs81/ConsoleHelp/jta.html
A heuristic completion (or heuristic decision) occurs when a resource makes a unilateral decision during the completion stage of a distributed transaction to commit or rollback updates. This can leave distributed data in an indeterminate state. Network failures or resource timeouts are possible causes for heuristic completion. In the event of an heuristic completion, one of the following heuristic outcome exceptions may be thrown:
HeuristicRollback—one resource participating in a transaction decided to autonomously rollback its work, even though it agreed to prepare itself and wait for a commit decision. If the Transaction Manager decided to commit the transaction, the resource's heuristic rollback decision was incorrect, and might lead to an inconsistent outcome since other branches of the transaction were committed.
HeuristicCommit—one resource participating in a transaction decided to autonomously commit its work, even though it agreed to prepare itself and wait for a commit decision. If the Transaction Manager decided to rollback the transaction, the resource's heuristic commit decision was incorrect, and might lead to an inconsistent outcome since other branches of the transaction were rolled back.
HeuristicMixed—the Transaction Manager is aware that a transaction resulted in a mixed outcome, where some participating resources committed and some rolled back. The underlying cause was most likely heuristic rollback or heuristic commit decisions made by one or more of the participating resources.
2. Understanding EJB Transaction
http://www2.sys-con.com/itsg/virtualcd/Java/archives/0504/tyagi/index.html
Unilateral Decisions
The transaction manager allows certain heuristic or speculative decisions to be made based on the state of all participating resources in a transaction and the underlying two-phase commit protocol. A heuristic decision occurs when one of the resources in the transaction unilaterally decides to commit or roll back the transaction without permission from the transaction manager
3. Oracle® Containers for J2EE
http://download.oracle.com/docs/cd/B31017_01/web.1013/b28958.pdf
Heuristics
To achieve consensus, two-phase commit is a blocking protocol. This means that, if a coordinator fails before delivering the final phase messages, the participants must remain blocked, holding onto resources. Modern transaction systems add heuristics to two-phase commit, which allows such participants to make unilateral decisions about whether they will commit or rollback. If a participant makes a choice that turns out to be different from the one taken by other participants, then non-atomic behavior occurs.
I got this problem while trying to do a distributed J2EE tarnsaction with two XA (one MQ and other Oracle 10g database XA) and one non-xa (oracle 10g database). According to above docs a resource manager can decide tarnsaction final state unilaterally and that can result in unatomic transaction.
Do oracle also make such decision and if yes then on what ground it takes decision? Can we change this according to our requirement either always rollback/commit anywhere as parameter setting?
Thanks

Which processor is best for Oracle 10G database : Intel or AMD

Hi,
I am buying a new laptop for 34000 rs (700$) . I am configuring it for my office use. i am oracle apps developer.
Can anyone suggest shud i go for Caompaq or Acer?
Which processor will best handle Oracle 10G database? Inter Core Duo or AMD Turion?
Thanks,

The laptop i m buying is *250 GB HDD, 2 GB RAM and windows vista*.As Nicolas has rightly pointed out in his post, which version of Vista is this? Remember that Vista Home edition is not supported by Oracle. You might get the things to run but you cannot guarantee the stability.
The only thing i m confused bout is whther i shud go for AMD or Inter core processor.
In this case, this would be a matter of personal choice. Both processors are at par with each other (now I am not going into the details of architecture and other things).

Hi Prasanth
Yes that should be possible but is it a production database or just a test database.
you can always control that in metalink if it is supported, I don't believe it is.
Read that documentation to perform the installation.
