Polularity of Oracle Database

Iam looking for a Oracle Certification in Oracle 9i DBA. Before i register with any of the authorised oracle center,i would like to know that on what platform Oracle Database is more popular... is it Windows Or Unix?
The clarification here is not about the ease of getting the certification on any platform, but it is about the market value.
please advise by return
Thanks & best regards
- Mohammed Yusuff

Just a quick thought but probably best to learn it on a Unix type platform. The Windows version is easy enough but learn the in and outs of Unix and you will probably gain more. Big companies from what I have seen run Oracle on Unix machines. But I have seen some smaller shops and even bigger running it on windows server. Either way you will learn something.

Query in timesten taking more time than query in oracle database

Hi,
Can anyone please explain me why query in timesten taking more time
than query in oracle database.
I am mentioning in detail what are my settings and what have I done
step by step.........
1.This is the table I created in Oracle datababase
(Oracle Database 10g Enterprise Edition Release 10.2.0.1.0)...
CREATE TABLE student (
id NUMBER(9) primary keY ,
first_name VARCHAR2(10),
last_name VARCHAR2(10)
2.THIS IS THE ANONYMOUS BLOCK I USE TO
POPULATE THE STUDENT TABLE(TOTAL 2599999 ROWS)...
declare
firstname varchar2(12);
lastname varchar2(12);
catt number(9);
begin
for cntr in 1..2599999 loop
firstname:=(cntr+8)||'f';
lastname:=(cntr+2)||'l';
if cntr like '%9999' then
dbms_output.put_line(cntr);
end if;
insert into student values(cntr,firstname, lastname);
end loop;
end;
3. MY DSN IS SET THE FOLLWING WAY..
DATA STORE PATH- G:\dipesh3repo\db
LOG DIRECTORY- G:\dipesh3repo\log
PERM DATA SIZE-1000
TEMP DATA SIZE-1000
MY TIMESTEN VERSION-
C:\Documents and Settings\dipesh>ttversion
TimesTen Release 7.0.3.0.0 (32 bit NT) (tt70_32:17000) 2007-09-19T16:04:16Z
Instance admin: dipesh
Instance home directory: G:\TimestTen\TT70_32
Daemon home directory: G:\TimestTen\TT70_32\srv\info
THEN I CONNECT TO THE TIMESTEN DATABASE
C:\Documents and Settings\dipesh> ttisql
command>connect "dsn=dipesh3;oraclepwd=tiger";
4. THEN I START THE AGENT
call ttCacheUidPwdSet('SCOTT','TIGER');
Command> CALL ttCacheStart();
5.THEN I CREATE THE READ ONLY CACHE GROUP AND LOAD IT
create readonly cache group rc_student autorefresh
interval 5 seconds from student
(id int not null primary key, first_name varchar2(10), last_name varchar2(10));
load cache group rc_student commit every 100 rows;
6.NOW I CAN ACCESS THE TABLES FROM TIMESTEN AND PERFORM THE QUERY
I SET THE TIMING..
command>TIMING 1;
consider this query now..
Command> select * from student where first_name='2155666f';
< 2155658, 2155666f, 2155660l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.668822 seconds.
another query-
Command> SELECT * FROM STUDENTS WHERE FIRST_NAME='2340009f';
2206: Table SCOTT.STUDENTS not found
Execution time (SQLPrepare) = 0.074964 seconds.
The command failed.
Command> SELECT * FROM STUDENT where first_name='2093434f';
< 2093426, 2093434f, 2093428l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.585897 seconds.
Command>
7.NOW I PERFORM THE SIMILAR QUERIES FROM SQLPLUS...
SQL> SELECT * FROM STUDENT WHERE FIRST_NAME='1498671f';
ID FIRST_NAME LAST_NAME
1498663 1498671f 1498665l
Elapsed: 00:00:00.15
Can anyone please explain me why query in timesten taking more time
that query in oracle database.

Using Oracle ODBC Gateway connecting to a remote Oracle database

Oracle 11gR2
RHEL 6.4
Has anyone use the Oracle ODBC Gateway to connect to another Oracle database? Any issues with that configuration? Where do I get the ODBC drivers for Linux?
(I know, "why not use a dblink?" -- well that would be against company security policies)

Hi,
From the Oracle point of view we support using DG4ODBC for Oracle to Oracle connections. However, we have not actually tested it as DG4ODBC is primarily designed for access to non-Oracle databases.
How DG4ODBC will work between Oracle databases depends on the ODBC driver and what that supports. You will need an ODBC Oracle driver which you can get from various suppliers including Oracle but also vendors such as DataDirect, Easysoft etc. You could try a Google search.
You say you do not want to use database links but that is how DG4ODBC is used, You cannot do -
sqlplus user/password@dg4odbc_oracle
Once Dg4ODBC is setup and configured as in this note - if you are using Linux 64-bit -
How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle Databases Post Install (Doc ID 561033.1)
then in the Oracle database you create a database link and select from tables in the other Oracle database -
select * from table@dg4odbc_db_link ;

Problem with httpd and oracle database

hi
i have oracle linux with oracle database 11gR2
i install php with oci as the following link :
http://oss.oracle.com/projects/php/dist/documentation/installation.html
but when i try phpinfo() i found just only
*" /etc/php.d/oci8.ini"* in the result
and when i test connection i have this error
*" Fatal error: Call to undefined function oci_connect() "*
so what is the best way to install oci on oracle linux ?

What version of the OS are you using? Any clues in the syslog and httpd log? Are you using SELinux, which is often an overlooked issue?
Can you provide more details?
so what is the best way to install oci on oracle linux ?According to the instructions, if support is needed: http://www.oracle.com/technetwork/topics/php/zend-server-096314.html

Hi
Your import database use a multibyte characterset, your export db a singlebyte cs.
This means, a char can need more than 1 byte.
Try this before import (and before create tables!!):
alter system set nls_length_semantics=char;Greetings

How to take Input from the callers telephone keypad into oracle database

My client requires to automate a registration task for his customers by telephone. The requirement is the Oracle database should take numeric input from the callers telephone keypad eg 1 or 2 or 3 and the oracle must store this input inside its database and do some required processing with such input and generate a unique numeric id (sequence) and send back this unique numeric ID to the caller who is on hold. Please Note. Is there any electronic device to be installed at the client site to solve the above task eg. any telephone line to be connected to the CPU and etc?
I completely have zero knowledge. Please can you outline/summarise the instructions how to construct and install to meet my client requirement.
If this is not possible in Oracle I Can migrate to any database. Please suggest.
please help me. if you cant help i appretiate if you give me some clues

You need to start with your telephone system. Normally this situation would involve some sort of PBX or other internal switching equipment. Talk to your vendor. There's likely to be software, etc. available to perform the interaction with the end user.
It should have programmable "hooks" to interface with various databases. To Oracle it just looks like another program.

Help needed to loadjava apache poi jars into oracle database.

Help needed to loadjava apache poi jars into oracle database. Many classes left unresolved. (Poi 3.7, database 11.1.0.7). Please share your experience!

Hi,
The first 3 steps are just perfect.
But with
loadjava.bat -user=user/pw@connstr -force -resolve geronimo-stax-api_1.0_spec-1.0.jar
the results are rather unexpected. Here is a part of the log file:

This class exists in the SYS schema though and is valid. If SYS should be included as a resolver? How to solve this problem?

Difference between upgrdae and migration about oracle database

Difference between upgrdae and migration about oracle database
please give the comments

Well, the question is almost philosophic... 
In 9i, there is a Migration Guide whereas in 10g there is a Upgrade Guide. 
Furthermore, in 9i, there is the command line startup migrate whereas in 10g that's startup upgrade.
Somebody think upgrade when go to new release, and migration when go to new version. 
Others think upgrade when new version replace database in place, and migration when new version include a move of database. 
Another point of view is : upgrade is for technical, and migration for application/data. 
 
Well, after these explanations, your upgrade/migratation notion will not be more clear, but I think that is not very important, only a terminology game. The most important is to know what you need : new version or new release.

Error in CLOB datatype for transfering data from Excel to Oracle database

Am using excel sheet as source and Oracle as target Database.
For all tables the operations works smoothly except for tables containing CLOB datatype.
Initially i have used SQL Developer to transfer some data into excell sheets, now i want to transfer those file's data into another Oracle Database.
What other options do i have?
Is excel not the right tool to transfer CLOB datatypes?

well,
I couldn't suggest an excel to do it...
You can go from Oracle to Oracle with the PL/SQL IKM. It works fine.
Does it help you?

Oracle database 11g release 2 installation problem on windows 7 (64-bit)

First of all my windows is not genuine, but on my friend's desktop oracle download and installation worked fine, he chose "create and configure database" options, and it works very well on his desktop, though his windows is also illegitimate. In my case, when I select "Create and configure database" option and pressed 'next",
(Go to my blog to see it with snapshots: Computer Science: Oracle database 11g release 2 installation problem on windows 7 (64-bit))
it asks to select class, I select "Desktop class" and pressed "next". The moment I pressed "next", the whole setup thing disappeared like it was never started. I searched for all possible reasons for why its not getting installed on my laptop, I used registry cleaner s/w, deleted 25 GB of data to create free space if it were the problem, increased the virtual memory to increase the space for RAM, I did almost everything to get this setup working, but I found no success with the "Create and Configure database" option
and
then
I chose a "database software only" option and chose to store in a folder w/o spaces. This way, I got database s/w only and then later I found "Database configuration Assistant (DBCA)" from windows START button and clicked to create and configure database manually. The steps are pretty much interactive and doesn't involve much brainstorming.
The values I filled for
1) Global Database Name : orcl
2) System Identifier : orcl
3) I chose common password for both SYS and SYSTEM
4) while on Enterprise Manager Configuration step, It asked me to create and configure listener in oracle home, so for that too, I typed "netca" in windows START menu and clicked it. There I added a listener.
5) I chose a Storage area which was the Oracle-home itself i.e. where our installation files goes , in my case it is : C:\oracle_base\product\11.2.0\dbhome_1\oradata
6) Then after few more nitty-gritty clicks, we are set to go !
Finally to write SQL code and to create your first TABLE , type "sqlplus" in windows "START" menu and click it when it appears. A command-prompt like window appears , which will ask you for username and password, so here they are :
Username : sys/ as sysdba
Password : (its the one you created in step 3 stated above )
After this you are ready to write your first SQL command.

Is this your solution to your original post at Oracle database 11g release 2 installation on windows 7 (64-bit) ?
Pl be aware that you should not create any custom objects in SYS or SYSTEM schema - you should create any such objects in a separate custom schema.

Check pushitz website and ensure that you have all the required rpms installed properly.
Check the log files in the installation directory. That should give some more details as to what exactly is going on.

Hi Everyone,
I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:
An error was encountered performing the required operation Got a minus one from read call .Vendor code 0
However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.
My TNSNAMES .ora file is as follows:

I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad 10.5.0.41. It give me the following error:
ORA 12537 : TNS Connection closed
Thanks for your patience and help in advance.

Unable to continue Oracle Database 10g R2 installation on IBM AIX 5.3L

I am facing some difficulties in installing the above. My environment is as follows:
Server is a IBM system P, OS is AIX 5.3L and oracle version is Oracle Database 10g R2 (10.2).
I encounter my problem when asked to changed/edit the shell script when changing oracle users. I can't find the % vi .login file. And I'm not sure how to proceed.
Please advice as to what needs to be done.
Thank you

i'm using bash shell.If you are using a bash shell then .bash_profile is used by default.
It is located in user's home, if it does not exist then simply create it.
can this file be edited after installation?Yes. And also you can set the enviroment temporary (just for current session)
I just can't find the vi .login file."vi" is command (text editor very common in Unix and Unix like world)
.login does not need to exist (see .bash_profile as above). Note .login is ignored by bash shell.

Running oracle database xe (express edition) on windows server 2008 r2

Is it supported to run Oracle Database XE on Windows Server 2008 R2?
Database XE is only supported as 32-bit. Current builds of Windows Server 2008 only come in x64 configurations.
Here are the Database XE system requirements for windows:
[http://docs.oracle.com/cd/E17781_01/install.112/e18803/toc.htm]
The docs say that 32-bit windows is required, yet they also say that windows server 2008 is supported.
Windows Server 2008 R2 came out in 2009, and in R2 they eliminated 32-bit OS (though there is the WOW64 subsystem to run 32-bit programs within the 64-bit OS).
See:
- [Wikipedia page about windows server 2008 with info on R2|http://en.wikipedia.org/wiki/Windows_Server_2008#Windows_Server_2008_R2]
- [Wikipedia page on "windows 32-bit on windows 64-bit"|http://en.wikipedia.org/wiki/WOW64]
Thanks,
Matt

Hello Matt,
Is it supported to run Oracle Database XE on Windows Server 2008 R2?No.
The docs say that 32-bit windows is required, yet they also say that windows server 2008 is supported.So this means that only 32bit versions of 2008 will be supported.
Windows Server 2008 R2 came out in 2009, and in R2 they eliminated 32-bit OS (though there is the WOW64 subsystem to run 32-bit programs within the 64-bit OS).Which is probably why 2008 R2 is not supported.
You can either take the VM approach and install a 32 bit Windows or 64 bit Linux host, or you can queue in the list of persons waiting for a 64 bit Windows release. See the following thread for details (and the queue) for the latter: {thread:id=2277728}
