Oracle 10g features

Hi
Please provide some information on Oracle 10g features.
Thank you

Hi,
Are you looking for all features or new features??
For all features (in case you're new to Oracle), I guess you need to go through the Oracle Documentation for Oracle 10g [http://download.oracle.com/docs/cd/B19306_01/index.htm]
In case you're looking for new features, go to [http://download.oracle.com/docs/cd/B19306_01/server.102/b14214/toc.htm]
Thanks,

Oracle 9i and oracle 10g features

Looking for some info/link which could help me in understanding the newer features in oracle 9i database and in 10g dbase.
Will be good to know the additional features which are in 10g release but not in 9i.

Go to the documentation.
Look for the book called 'New Features'. It's big, but it's only an overview.
When you find new features of interest, go to the manual for that feature and look in the area between he table of contents and Chapter 1 - the area titled 'New Features' - for more explanation.
Surprisingly, documentation can be useful - you get a lot less sarcasm and typos in the docco <g>

Using complete oracle 10g features....

I do have the documentation but acccording to my personal experince this forum with gurus aroun here is better
i wud like to noe how to make the best use of forms 10g like
making good graphically appealing form,increased funcationality how to incude flash objects,
n whats the use of using import java classes, import OLE interface and how to select the specific class or the package according to the requirements...i.e how to use and when to use them..!!!
will it be easy to create webbased applications using Jdeveloper or will it b better to use forms....???

my 5 cent:
making good graphically appealing form,what does that mean?
increased funcationality how to incude flash objectsthere is a java-bean that can be used as a "Web-Browser inside forms" that supports Flahs animations ( http://forms.pjc.bean.over-blog.com/article-5029633.html )
n whats the use of using import java classes, Java-classes can be imported to enhance the functionality with logic written in java. The java-coe gets executed on the application-server. An example might be the logic to call a webservice.
import OLE interface OLE is a windows-technique to somehow "remote-control" windows-applications or functionality provided in Active-X-dlls. OLE-calls work on the client (and in 10G require WEBUTIL)
and how to select the specific class or the package according to the requirements...i.e how to use and when to use them..be more specific
will it be easy to create webbased applications using Jdeveloper "42", or in other words, "it depends".
It will be easy if you are capable of the nechnologies you need. JDeveloper is not a technology but a tool for java-development which supports the development of web-applications. But, there are a lot of web-technologies based on java which you can use. For more details you might read some stuff about JEE
or will it b better to use forms....???Also, it depends. There are certain areas where Forms will be better (or easier, or more productive) to use. As forms requires a somehow "fat" client with the installation of the Java-Runtime and certain permissions for the applet to work properly, it may not be the first choice if you implement some public web-application. For "inhouse"-applications run on a companies intranet which deal with "alphanumerical data", forms may be the better choice because of a more Windows-like behaviour and/or its great productivity. (Both are just examples, you'll have to decide which technology to use based on certain reuqirements for a certain application)

"In-Memory Database Cache" option for Oracle 10g Enterprise Edition

Hi,
In one of our applications, we are using TimesTen 5.1.24 and Oracle 9i
databases (platform - Solaris 9i).
TimesTen holds application information which needs to be accessed quickly
and Oracle 9i is a master application database.
Now we are looking at an option of migrating from Oracle 9i to Oracle 10g
database. While exploring about Oracle 10g features, came to know about
"In-Memory Database Cache" option for Oracle Enterprise Edition. This made
me to think about using Oracle 10g Enterprise Edition with "In-Memory
Database Cache" option for our application.
Following are the advantages that I could visualize by adopting the
above-mentioned approach:
1. Data reconciliation between Oracle and TimesTen is not required (i.e.
data can be maintained only in Oracle tables and for caching "In-Memory
Database Cache" can be used)
2. Data maintenance is easy and gives one view access to data
I have following queries regarding the above-mentioned solution:
1. What is the difference between "TimesTen In-Memory Database" and
"In-Memory Database Cache" in terms of features and licensing model?
2. Is "In-Memory Database Cache" option integrated with Oracle 10g
installable or a separate installable (i.e. TimesTen installable with only
cache feature)?
3. Is "In-Memory Database Cache" option same as that of "TimesTen Cache
Connect to Oracle" option in TimesTen In-Memory Database?
4. After integrating "In-Memory Database Cache" option with Oracle 10g, data
access will happen only through Oracle sqlplus or OCI calls. Am I right here
in making this statement?
5. Is it possible to cache the result set of a join query in "In-Memory
Database Cache"?
In "Options and Packs" chapter in Oracle documentation
(http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/options.htm
#CIHJJBGA), I encountered the following statement:
"For the purposes of licensing Oracle In-Memory Database Cache, only the
processors on which the TimesTen In-Memory Database component of the
In-Memory Database Cache software is installed and/or running are counted
for the purpose of determining the number of licenses required."
We have servers with the following configuration. Is there a way to get the
count of processors on which the Cache software could be installed and/or
running? Please assist.
Production box with 12 core 2 duo processors (24 cores)
Pre-production box with 8 core 2 duo processors (16 cores)
Development and test box with 2 single chip processors
Development and test box with 4 single chip processors
Development and test box with 6 single chip processors
Thanks & Regards,
Vijay

Hi Vijay,
regarding your questions:
1. What is the difference between "TimesTen In-Memory Database" and
"In-Memory Database Cache" in terms of features and licensing model?
==> Product has just been renamed and integrated better with the Oracle database - Times-Ten == In-Memory-Cache-Database
2. Is "In-Memory Database Cache" option integrated with Oracle 10g
installable or a separate installable (i.e. TimesTen installable with only
cache feature)?
==> Seperate Installation
3. Is "In-Memory Database Cache" option same as that of "TimesTen Cache
Connect to Oracle" option in TimesTen In-Memory Database?
==> Please have a look here: http://www.oracle.com/technology/products/timesten/quickstart/cc_qs_index.html
This explains the differences.
4. After integrating "In-Memory Database Cache" option with Oracle 10g, data
access will happen only through Oracle sqlplus or OCI calls. Am I right here
in making this statement?
==> Please see above mentioned papers
5. Is it possible to cache the result set of a join query in "In-Memory
Database Cache"?
==> Again ... ;-)
Kind regards
Mike

Recommended books for Oracle 10g

I'm new to this group, so my apologies in advance if this is not the appropriate group for this question. If it is not, please steer me in the right direction. Thanks!
Here's my situation: I'm currently a Microsoft SQL Server developer and have been for about 6 years, so I'm fairly conversant with SQL. Our company is in the process of purchasing an application that runs under Oracle 10g, and I need to learn as much as I can as quickly as I can about 1) being the Oracle DBA for our (small) company, and 2) developing in Oracle SQL.
Are there any specific books some of you would recommend for my particular situation (beginning level Oracle user, intermediate/advanced in SQL)? Any and all advice/suggestions/help will be gratefully accepted.
Thanks in advance --
Carl

First thing I would recommend is going in the OTN and download the 2 day dba article
and the top 20 Oracle 10g features

Oracle 10g Scheduled Backup

Hai,
I submitted a job using oracle 10g feature of scheduled backup feature in Windows environment.
When I selected the option of disk the screen displays the message that the backup will be in Flash Recovery Area in Windows environment.
Please let me know in what extension the file will be created and the entire path where the backup file will be stored. (windows environment)
Thanks and Regards,
A.Mohammed Rafi.

You will get directory Flash_recovery_area under ORACLE_BASE env variable.
You can do Sho Parameter Flash_recover_area.Format is depends upon which format u have given or you are using default format.clear which one recovery files u are looking for .

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.

New features in Oracle 10g

Hi,
is someone able to say what new features will be included in Oracle 10g from Workspace Manager point of view? I've looked on http://otn.oracle.com/oramag/webcolumns/2003/techarticles/new_features_preview.pdf but there is nothing about OWM. Particularly I'm interested in:
1. Possibility of historical data archiving and reloading - see topic Historic data in version enabled tables
2. More sophisticated support for database export/import (there is possible to export/import full database only)
3. Java API for OWM - see topic Java API for OWM?
Thanks
Ondrej

1. Possibility of historical data archiving
This is not available in 10G
2. More sophisticated support for database export/import (there is possible to export/import full database only)
Table level import//export is supported in 10G
3. Java API for OWM
No Java API support in 10G

Arun

Oracle 10G Browse object feature

Hi there
I am new to oracle, i have used browse Object in oracle 10g as an easy way to create my table instead of scripting.
however, i don't know how to assign two FK to the same table (employee table that contains Managers).
can anyone tell me in steps how i can do it using the browse object feature ?
Many thanks
ok, i found it but still have an issue. how to represent a recursive relation ship and again using the browse object feature in oracle. i tried to designate fk Mgr_id to the table employee which has a pk emp_id.
when i start insert rows to the existence column the following erorr appears:
" error ORA-02291: integrity constraint (SYSTEM.EMPLOYEE_CON) violated - parent key not found "
any idea guys ?
Edited by: Nader_ly on Jan 9, 2011 11:54 AM

" error ORA-02291: integrity constraint (SYSTEM.EMPLOYEE_CON) violated - parent key not found "
any idea guys ?FK prevents adding row to child table when no parent row exists

Document about Oracle 10g New Features

Oracle 10g new feature to backup to tape?

I heard rumours that Oracle 10g has new features to backup to tape directly. I don't know exactly how this is done, and I'd like the experts to comment. What I've discovered so far is that there is this program called Legato Single Server Version (LSSV) which ships with the Oracle 10g Companion CD which makes RMAN use the tape directly as a medium to backup. Is this CD available for download?

I am truly curious why you actively ask to avoid the "New Features Guide" which provides much of the information you desire.

Thanks,

I assume you have Windows on the client. The "Drivers" page of the ODBC_DSA should list all installed drivers. You require:
name= Oracle ODBC Driver
version= 8.01.07.00 (or something similar)
company= Oracle Corporation DO NOT USE the Microsoft one.
If this does not show, then either it was not included in the Oracle Client installation or you have not rebooted after the Oracle Client installation; the ODBC driver is not visible until rebooted.

Oracle 10g editions features

for oracle 10g different editions, regarding Maximum CPUs feature, it is mentioned that for
Standard Edition One - Maximum CPUs - 2
Standard Edition - Maximum CPUs - 4
Enterprise Edition - Maximum cPUs - Unlimited.
does this means that Server on which database is to be installed has 8 CPUs then in case of Standard Edition One- it will use only 2 CPUs out of 8
In case of Standard Edition - it will use 4 CPUs out of 8
In case of Enterprise Edition - it will use all the 8 CPUs.
Regards

does this means that Server on which database is to
be installed has 8 CPUs ...To license Oracle for a server with the capacity of more than 4 cpus or sockets, you have the choice of Enterprise Edition. Note the multi-core aspect.
http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABGIECI
However, you (or someone in your company) need to get in touch with your Oracle account rep to discuss these licensing and contractual matters. (It is not as straightforward as your second or third impression may let you believe)

What are the new features of Oracle 10g over Oracle9i

Hi Grus..
i want to know what are the new features of oracle 10g over Oracle 9i as well oracle 11g over 10g.. can any one give me the detailed document.
Because I'm struggling each and every time while the interviewer asked above question.
It's very helpful for me if any one give me the detailed document regarding above question
Thanks In Advance
Arun

Hi,
Just check below link..would be helpful..
http://www.oracle.com/global/ap/openworld/ppt_download/database_manageability%2011g%20overview_230.pdf
and
Each release of Oracle has many differences, and Oracle 10g is a major re-write of the Oracle kernel from Oracle 9i. While there are several hundred new features and other differences between 9i and 10g, here are the major differences between Oracle9i and Oracle10g:
Major changes to SQL optimizer internals
Oracle Grid computing
AWR and ASH tables incorporated into Oracle Performance Pack and Diagnostic Pack options
Automated Session History (ASH) materializes the Oracle Wait Interface over time
Data Pump replaces imp utility with impdp
Automatic Database Diagnostic Monitor (ADDM)
SQLTuning Advisor
SQLAccess Advisor
Rolling database upgrades (using Oracle10g RAC)
dbms_scheduler package replaces dbms_job for scheduling
and you need to refer oracle documentation for sql, plsql references where you will know particular enhancements made...
thanks
