Hi,
I would suggest you start working on Oracle 11g rather Oracle 10g.
Download and install the software on your PC from here.
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
Since you have worked on Oracle 7.0 and Oracle 8.0 I take it you are not new to SQL and PL/SQL. I guess the bit you might lack is the usage of new functionalities introduced in the recent versions.
To learn the new features just follow this forum with the questions posted and try to solve the problem on your own. Once you have solved it compare your resolution with the resolution posted in this forum. I would say this is the more easy and efficient way to learn.
Also follow the posting in asktom.oracle.com.
Hope this helps.
Regards
Raj

Oracle 10g - Introduction to SQL course question

Two years ago I completed the Oracle 9i - Introduction to SQL course. An complete the #1Z0-007 exam and pass with almost 100%.
I notice that Oracle 10g - Introduction to SQL courses are now being offer. If I have already done the Oracle 9i course and have been using SQL for the pass two years. Is doing the Oracle 10g - Introduction to SQL worthwhile ?
Will I learn anything new or is the course almost the same ?
Thanks
Brendon

Brendon,
Almost certainly not useful. I'd compare the contents of the course you did with the features that have been introduced into Oracle since the version that the course was based on, and try to find some material on these features.
Cheerio,

Problem to connect between Oracle 10g xe and VB2010 at Vista sp2

Introduction
Hi guys, good day... NEED RESCUE!! SOS!! Hmm.. i have trouble been 1 weeks trying connect between Oracle 10g xe and VB2010 on window vista sp2. Actaully im very new at Oracle 10g xe and VB2010 but i got a project is going to build up system database and i figure out Oracle 10g xe and VB2010 can use free so i just chows these appication to be my project. I been search around internet and there is several things i was found about the connection but i has try and tried still it wont work out.
Things i found and learned
Oracle
1. I have download Oracle 10g XE and installed in my windows vista sp2.
2. I notice the Oracle Developer Tools is needed for VB2010 (To add reference 'Oracle.DataAccess'). So i was downloaded ODT11beta and installed
3. I also edit TNSNAMES to following below:
OraDb =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = shin-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
4. My sqlnet like following below:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
5.I have try tnsping OraDB and its works.
6. I monitoring task manager and OracleServicesXE is running.
7. ora_dba is added in Group.
Problem in SQLPLUS
When i try connect SQLPLUS in cmd i get ERROR: ORA-12560: TNS:protocol adapter error.
i . In cmd i type sqlplus and enter then i been ask for username and password.
ii. After i insert my username and password and enter then i get the error of ORA-12560.
Visual Basic 2010
1. First i created my project, drawing label and button for test connection.
2. Then, i add reference Oracle.DataAccess into my project.
3. I type following script into my vb form:
Imports System.Data
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Logon
Private Sub cmdLogon_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLogon.Click
Dim oradb As String = "Data Source = OraDb; User Id = system; Password = shin;"
Dim conn As New OracleConnection(oradb)
conn.Open()
Dim cmd As New OracleCommand
cmd.Connection = conn
cmd.CommandText = "select SName from Staff where SName = shin"
cmd.CommandType = CommandType.Text
Dim dr As OracleDataReader = cmd.ExecuteReader()
dr.Read()
lblOra.Text = dr.Item("SName")
conn.Dispose()
End Sub
End Class
Problem in VB2010
When i run my project and press the button i get error message ORA-12514: TNS:could not resolve the connect identifier specified at conn.Open()
Extra Question*
1. Im notice in my netbook xp home sp2, before i install ODT11beta my sqlplus look fine thought cmd but after i installed ODT11beta its same problem with my Vista sp2 now. Get error ORA-12560: TNS:protocol adapter error :( I tried uninstall ODT11beta again and restart its work fine again. Which i really dun understand. Izzit the version ODT11 is not suitable for 10g xe? And i dunno this problem is related with my connection between oracle 10g xe and vb2010 or not. So confuse@@
2. I wish to know more about connect between Oracle and VB, is there still a things i miss?(I mean steps or configuration that should i done)
3. Or i just lower my VB version could make more easy? If yes, what version VB should i use that could work out with oracle 10g xe?
4. Sorry for too bad my english but i really wish somebody could help me. Please try to understand my written or you could ask me mean if dont understand. Im stuck!! Stuck feel not really that good.....

Huhu..
Yo, henry
I thought the OraDb is just a name for entry but im not sure it is a service. I was refer http://www.oracle.com/technology/pub/articles/cook-vs08.html at topic Connection Strings and Objects.
Here is my lsnrctl service

Izzit ok? I notice there is no listed OraDb. but tnsping OraDb seem fine.
Actually there is somethings as a newbie i wondering long time alreadly ><
1. The origin of tnsname.ora is no OraDb or ORCL but i just simple add it by open tnsname.ora with notepad. Im just not sure it is function or not.
Also please check at my TNSNAME.ORA:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = shin-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)

OraDb =
(DESCRIPTION =

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
I got the feeling there is so close~~~!!!

Oracle 10G DBA OCP - for whom has Oracle 7 OCP

I am Oracle 7 certified and plan to have Oracle 10G certified by taking 1Z0-042 (dba 1) and 1Z0-043 (dba2 and workshop).
1. I remember I have taken SQL and PL/SQL when I was certified Oracle 7. Do I still need to one of the
1Z0-001 Introduction to Oracle: SQL and PL/SQL (retired)
or
1Z0-007 Introduction to Oracle9i SQL®
or
1Z0-047 Oracle Database SQL Expert
or
1Z0-051 Oracle Database 11g: SQL Fundamentals
2. can i find out from Oracle that my SQL/PLsql passed in oracle 7 OCP was 1Z0-001?
3. Can I take 1Z0-043 first since I took the class and plan to study 1Z0-042 on my own?
4. How many questions and the duration for the exam 1Z0-043 exactly? Oracle site indicated 92 questions form 90 minutes (it was 120 minutes last year), which is pretty short time for a person whose major language is not english.

MSSQL -- Oracle 10g migration

Hello,
I am a seasoned microsoft developer and I have been working almost exclusively with MSSQL (since 6.5) and Sybase. The company I work for has determined to stop all new MSSQL installs and go exclusively with Oracle 10g. Are there any resources or materials from a MS developers view point to help orient to Oracle technology? I've read the 2 - day DBA to help me get up to speed but reading material that translates it into familiar terms would certainly help me and others I work with get a reference point.
thanks,

Oracle 10g Admin-I is done, what next?

Hi,
I have completed Oracle 10g Admin I & SQL. Can i take Oracle 11g Admin II or i just have to completed Oracle 10g Admin II (Instructer Lead) exam and the go for an upgrade to 11g ?
Plz suggest.
Regards

Your question is not really clear. I'm going to take some guesses at what you mean and what you are asking
I have completed Oracle 10g Admin I & SQL.I'm guessing that by this you mean that you have passed two Oracle certification exams, presumably:
*1Z0-007     Introduction to Oracle9i SQL*
and
*1Z0-042     Oracle Database 10g: Administration I*
Can i take Oracle 11g Admin II I'm assuming that you are asking if you can take the following exam:
*1Z0-053     Oracle Database 11g: Administration II*
This exam is on a different track than 1Z0-042. The two cannot be combined for any certification.
or i just have to completed Oracle 10g Admin II (Instructer Lead) exam To complete the Oracle 10G certification, you must pass the following exam:
*1Z0-043     Oracle Database 10g: Administration II*
The exam itself is not instructor-lead, so I don't know what you mean by that. In addition to passing the test, you must attend instructor-lead training. The courses valid for the 10G track can be found here:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=244#2
and the go for an upgrade to 11g ?Once you have your 10G certification, you can upgrade to having an 11G OCP certification by passing the following exam:
*1Z0-050     Oracle Database 11g: New Features for Administrators*

Error while installing Oracle 10g on Fedora Core 1. After 40% of the Installation is thru, the progress bar is showing 40%, it gives error "Not connected to Oracle" and the installation has to be terminated.
We have tried by using the on-line procedure and changing the required script to make believe it as said.

Error while sending a mail using UTP_MAIL package in Oracle 10g

Hi,
We are using UTP_MAIL package to send a mail from Oracle 10g.We have follwed the following steps ...
SQL> connect sys/password as sysdba
Connected.
SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql
Package created.
Synonym created.
SQL> @$ORACLE_HOME /rdbms/admin/prvtmail.plb
Package body created.
SQL > alter system set smtp_out_server = '<mail_server_ip:25>' scope =spfile;
System altered..
Now we try the code
begin
utl_mail.send(
sender => 'sender's mail',
recipients => 'receiver mail',
CC => 'optional',
subject => 'Testing utl_mail',
message => 'Test Mail'
end;
But we get the following error...
ERROR at line 1:
ORA-29278: SMTP transient error: 421 Service not available
ORA-06512: at "SYS.UTL_SMTP", line 21

ORA-06512: at line 2
We also tried connecting to the mail server through telnet .But it is not getting connected..
Please help us to solve the issue.

From your own posting you may have the clue, if you try to access your mail server through telnet and it is not successful, it means the service is down or there are networking issues.
On pre 10gR2 versions there was a bug 4083461.8. It could affect you if you are on 10gR1
"Bug 4083461 - UTL_SMTP.OPEN_CONNECTION in shared server fails with ORA-29278 Doc ID: Note:4083461.8"
This was fixed on 10gR2 base and on 9.2.0.8.0

Stopping the Enterprise Manager Console (Oracle 10g on SuSE 9.1)

I'm trying to stop the Enterprise Manager Console by issuing the command:
${ORACLE_HOME}/bin/emctl stop dbconsole
Unfortunately, the command fails to stop the EM Console. Here's the output I get:
TZ set to US/Pacific
Oracle Enterprise Manager 10g Database Control Release 10.1.0.2.0

failed.
The only way I can stop the EM Console (and related services--i.e., emagent) is to kill its process.
Everything (Listener, DB Instance, EM Console) starts fine. I can stop the Listener and DB Instance without any problems. It's just the EM Console shutdown that doesn't happen cleanly.
Has anyone else encountered the same condition? If so, what was the solution?
Here's my operating environment:
SuSE 9.1 (Kernel 2.6.5-7.108-default)

Thanks in advance for any help/insight.

Has anyone else encountered the same condition? If so, what was the solution?Yes. Shutdown/reboot of the system made the error go away.
Sorry, no better clues,

Migration from Oracle 9i 32 bit to Oracle 10G 64 bit on Windows 2003 Server

I am working on migrating Oracle 9i 32 bit to Oracle 10G 64 bit on Windows 2003 from Old server to new server. We have db around 500 GB and 3 schemas. I installed Oracle 10G on new server, created tablespaces, schema's blah blah and now doing export and import at schema level from old server to new server.
Import is taking more than 4 to 5 hours on new server. My manager is saying, window time is bit longer and he wants me to try possiblities to make this process faster. Can some one help me on this, to use the best possible method to complete this process faster?
Will below step work, if I try?
If I install, oracle 9i and 10g both on new server in different home directories and take the hot backup from old machine and restore on new machine in 9i home directory and use the upgrade configuration assistant from 10g and do the upgrade? Pls advice.
Thanks in advance,
Hari babu
Edited by: user6367891 on Mar 2, 2010 5:28 AM

It looks good.
I have one question in below steps:
To migrate an Oracle9i or older database to an Oracle Database 10g Release 1 (10.1) database for 64-bit Windows:
1 Perform steps 1 - 11 in "Migrating an Oracle Database 10g Release 1 (10.1) Database".
2 Shut down the database on the 64-bit computer:
SQL> SHUTDOWN IMMEDIATE;
3 Start the database migration:
SQL> STARTUP MIGRATE;
4 Migrate the database as described in Chapter 3, "Upgrading a Database to the New Oracle Database 10g Release" in Oracle Database Upgrade Guide.
In step 4, it says, migrate database as described in chapter 3. In chapter 3, it says, to do the upgrade the process using dbca or manually. Pls confirm whether do the upgrade process after issuing startup migrate or not.
Thanks in advance.

Oracle 10G New Feature........Part 1

Dear all,
from last couple of days i was very busy with my oracle 10g box,so i think this is right time to
share some intresting feature on 10g and some internal stuff with all of you.
Have a look :-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Oracle 10g Memory and Storage Feature.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1.Automatic Memory Management.
2.Online Segment Shrink
3.Redolog Advisor, checkpointing
4.Multiple Temporary tablespace.
5.Automatic Workload Repository
6.Active Session History
7.Misc
a)Rename Tablespace
b)Bigfile tablespace
c)flushing buffer cache
8.ORACLE INTERNAL
a)undocumented parameter (_log_blocks_during_backup)
b)X$ view (x$messages view)
c)Internal Structure of Controlfile
1.Automatic memory management
================================
This feature reduce the overhead of oracle DBA.previously mostly time we need to set diff oracle SGA parameter for
better performance with the help of own experience,advice views and by monitoring the behaviour
of oracle database.
this was just time consuming activity.........
Now this feature makes easy life for oracle DBA.
Just set SGA_TARGET parameter and it automatically allocate memory to different SGA parameter.
it focus on DB_CACHE_SIZE
SHARED_POOL_SIZE
LARGE_POOL
JAVA_POOL
and automatically set it as
__db_cache_size
__shared_pool_size
__large_pool_size
__java_pool_size
check it in alert_log
MMAN(memory manager) process is new in 10g and this is responsible for sga tuning task.
it automatically increase and decrease the SGA parameters value as per the requirement.
Benefit:- Maximum utlization of available SGA memory.
2.Online Segment Shrink.
==========================
hmmmmm again a new feature by oracle to reduce the downtime.Now oracle mainly focus on availablity
thats why its always try to reduce the downtime by intrducing new feature.
in previous version ,reducing High water mark of table was possible by
Exp/imp
or
alter table move....cmd. but on these method tables was not available for normal use for long hrs if it has more data.
but in 10g with just few command we can reduce the HWmark of table.
this feature is available for ASSM tablespaces.
1.alter table emp enable row movement.
2.alter table emp shrink space.
the second cmd have two phases
first phase is to compact the segment and in this phase DML operations are allowed.
second phase(shrink phase)oracle shrink the HWM of table, DML operation will be blocked at that time for short duration.
So if want to shrink the HWM of table then we should use it with two diff command
first compact the segment and then shrink it on non-peak hrs.
alter table emp shrink space compact. (This cmd doesn't block the DML operation.)
and alter table emp shrink space. (This cmd should be on non-peak hrs.)
Benefit:- better full table scan.
3.Redolog Advisor and checkpointing
================================================================
now oracle will suggest the size of redo log file by V$INSTANCE_RECOVERY
SELECT OPTIMAL_LOGFILE_SIZE
FROM V$INSTANCE_RECOVERY
this value is influence with the value of FAST_START_MTTR_TARGET .
Checkpointing
Automatic checkpointing will be enable after setting FAST_START_MTTR_TARGET to non-zero value.
4.Multiple Temporary tablespace.
==================================
Now we can manage multiple temp tablespace under one group.
we can create a tablespace group implicitly when we include the TABLESPACE GROUP clause in the CREATE TEMPORARY TABLESPACE or ALTER TABLESPACE statement and the specified tablespace group does not currently exist.
For example, if group1 is not exists,then the following statements create this groups with new tablespace
CREATE TEMPORARY TABLESPACE temp1 TEMPFILE '/u02/oracle/data/temp01.dbf'
SIZE 50M
TABLESPACE GROUP group1;
--Add Existing temp tablespace into group by
alter tablespace temp2 tablespace group group1.
--we can also assign the temp tablespace group on database level as default temp tablespace.
ALTER DATABASE <db name> DEFAULT TEMPORARY TABLESPACE group1;
benefit:- Better I/O
One sql can use more then one temp tablespace
5.AWR(Automatic Workload Repository):-
================================== AWR is built in Repository and Central point of Oracle 10g.Oracle self managing activities
is fully dependent on AWR.by default after 1 hr, oracle capure all database uses information and store in AWR with the help of
MMON process.we called it Memory monitor process.and all these information are kept upto 7 days(default) and after that it automatically purge.
we can generate a AWR report by
SQL> @?/rdbms/admin/awrrpt
Just like statspack report but its a advance and diff version of statspack,it provide more information of Database as well as OS.
it show report in Html and Text format.
we can also take manually snapshot for AWR by
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
**The STATISTICS_LEVEL initialization parameter must be set to the TYPICAL or ALL to enable the Automatic Workload Repository.

Benefit:- Now DBA have more free time to play games.....................:-)
Advance version of statspack
more DB and OS information with self managing capabilty
New Automatic alert and database advisor with the help of AWR.
6.Active Session History:-
==========================
V$active_session_history is view that contain the recent session history.
the memory for ASH is comes from SGA and it can't more then 5% of Shared pool.
So we can get latest and active session report from v$active_session_history view and also get histortical data of
of session from DBA_HIST_ACTIVE_SESS_HISTORY.
v$active_session_history include some imp column like:-
~SQL identifier of SQL statement
~Object number, file number, and block number
~Wait event identifier and parameters
~Session identifier and session serial number
~Module and action name
~Client identifier of the session
7.Misc:-
========
Rename Tablespace:-
=================
in 10g,we can even rename a tablespace by
alter tablespace <tb_name> rename to <tb_name_new>;
This command will update the controlfile,data dictionary and datafile header,but dbf filename will be same.
**we can't rename system and sysaux tablespace.
Bigfile tablespace:-
====================
Bigfile tablespace contain only one datafile.
A bigfile tablespace with 8K blocks can contain a 32 terabyte datafile.
Bigfile tablespaces are supported only for locally managed tablespaces with automatic segment-space management.
we can take the advantage of bigfile tablespace when we are using ASM or other logical volume with RAID.
without ASM or RAID ,it gives poor response.
syntax:-
CREATE BIGFILE TABLESPACE bigtbs
Flushing Buffer Cache:-
======================
This option is same as flushing the shared pool,but only available with 10g.
but i don't know, whats the use of this command in prod database......
anyway we can check and try it on test server for tuning n testing some query etc....
SQL> alter system flush buffer_cache;
System altered.
++++++++++++++++++
8.Oracle Internal
++++++++++++++++++
Here is some stuff that is not related with 10g but have some intresting things.
a)undocumented parameter "_log_blocks_during_backup"
++++++++++++++++++++++++
as we know that oracle has generate more redo logs during hotbackup mode because
oracle has to maintain the a complete copy of block into redolog due to split block.
we can also change this behaviour by setting this parameter to False.
If Oracle block size equals the operating system block size.thus reducing the amount of redo generated
during a hot backup.
WITHOUT ORACLE SUPPORT DON'T SET IT ON PROD DATABASE.THIS DOCUMENT IS JUST FOR INFORMATIONAL PURPOSE.
b)some X$ views (X$messages)
++++++++++++++++
if you are intresting in oracle internal architecture then x$ view is right place for getting some intresting things.
X$messages :-it show all the actions that a background process do.
select * from x$messages;
like:-
lock memory at startup MMAN
Memory Management MMAN
Handle sga_target resize MMAN
Reset advisory pool when advisory turned ON MMAN
Complete deferred initialization of components MMAN
lock memory timeout action MMAN
tune undo retention MMNL
MMNL Periodic MQL Selector MMNL
ASH Sampler (KEWA) MMNL
MMON SWRF Raw Metrics Capture MMNL
reload failed KSPD callbacks MMON
SGA memory tuning MMON
background recovery area alert action MMON
Flashback Marker MMON
tablespace alert monitor MMON
Open/close flashback thread RVWR
RVWR IO's RVWR
kfcl instance recovery SMON
c)Internal Structure of Controlfile
++++++++++++++++++++++++++++++++++++
The contents of the current controlfile can be dumped in text form.
Dump Level Dump Contains
1 only the file header
2 just the file header, the database info record, and checkpoint progress records
3 all record types, but just the earliest and latest records for circular reuse record types
4 as above, but includes the 4 most recent records for circular reuse record types
5+ as above, but the number of circular reuse records included doubles with each level
the session must be connected AS SYSDBA
alter session set events 'immediate trace name controlf level 5';
This dump show lots of intresting information.
it also show rman recordes if we used this controlfile in rman backup.

Oracle 10g - Defining the column name in Non English

Hi Experts,
I have an exisitng application which is developed on Windows using ASP Technology and uses Oracle 10g 10.1.0.2.0.
The application is supported with an instance of Data Base within which multiple tablespaces are created for different clients. The application is developed in such a way that some of the tables arecreated dynamically and the columns are named using the data entered through the UI.
This application needs to be globalized now. The problem is, the column name entered through the UI can be in any language based on the client's settings and those values in turn will be used for naming the columns in the tables.
1) Can I have the column names to be named using non english characters in Oracle 10g DB? If so,
1.1) what should I do to configure the exisiting Oracle instance to support it?
1.2) To what level is that configuration possible, is it per DB instance level (or) can it be done at Tablespace level. I would like to configure each tablespace to host tables with columns defined with different languages, say for example, tablespace 1 will have tables with Japaenese column names and tablespace 2 will have tables with German column names?
2) What should I do to make my entire DB to support unicode data i.e., to accept any language strings. Currently all strings are declared as VarChar2, should I change all VarChar2 to NVarChar2 (or) is there a way to retain the VarChar2 as is and make some database wide setting?
Please note that I do not have an option of retaining the column in English as per the Business Requirement.
Envionment:
OS - Windows 2003 32 bit
Oracle 10g 10.1.0.2.0
UI forms in ASP
TIA,
Prem

1. Yes, you can.
SQL> create table ÜÝÞ( ßàá number(10));
Table created.
SQL> insert into ÜÝÞ values (10);
1 row created.1.1 and 1.2 and 2. You can choose UTF as your default character set. It allows the user of non-English characters in VARCHAR columns in your whole database. It is not per tablespace.
SQL> create table ÜÝÞ( ßàá varchar2(100));
Table created.
SQL> insert into ÜÝÞ values ('âãäçìé');
1 row created.
