10 new features to the oracle dataabse 10g

Hi all.
Recently, I have been interivewed and I have been asked to list 10 new features of Oracle 10g.
I told him about:
1) Here, stats have been collected automatically, in oracle 9i it was manual
2) AWR
3) RULE based optimizer is not there only in oracle 9i
4) ASM
Anything else which you want to mentioned:

The Automatic Database Diagnostic Monitor (ADDM) analyzes data in the Automatic Workload Repository (AWR) to identify potential performance bottlenecks. For each of the identified issues it locates the root cause and provides recommendations for correcting the problem. An ADDM analysis task is performed and its findings and recommendations stored in the database every time an AWR snapshot is taken provided the STATISTICS_LEVEL parameter is set to TYPICAL or ALL. The ADDM analysis includes:
•     CPU load
•     Memory usage
•     I/O usage
•     Resource intensive SQL
•     Resource intensive PL/SQL and Java
•     RAC issues
•     Application issues
•     Database configuration issues
•     Concurrency issues
•     Object contention
ASM
Automatic Storage Management (ASM) simplifies administration of Oracle related files by allowing the administrator to reference disk groups rather than individual disks and files, which are managed by ASM
DBMS_FILE_TRANSFER Package in Oracle Database 10g•     Common Usage Notes
•     COPY_FILE
•     GET_FILE
•     PUT_FILE
Flashback New Features and Enhancements in Oracle Database 10g•     Flashback Query
•     Flashback Version Query
•     Flashback Transaction Query
•     Flashback Table
•     Flashback Drop (Recycle Bin)

Oracle Data Pump
STARTUP UPGRADE
The is a new startup mode associated with the upgrade procedure in Oracle 10g.
SQL> STARTUP UPGRADE
Automatic Shared Memory ManagementAutomatic Shared Memory Management puts Oracle in control of allocating memory within the SGA. The SGA_TARGET parameter sets the amount of memory available to the SGA. This parameter can be altered dynamically up to a maximum of the SGA_MAX_SIZE parameter value. Provided the STATISTICS_LEVEL is set to TYPICAL or ALL and the SGA_TARGET is set to a value other than "0" Oracle will control the memory pools which would otherwise be controlled by the following parameters:
•     DB_CACHE_SIZE (default block size)
•     SHARED_POOL_SIZE
•     LARGE_POOL_SIZE
•     JAVA_POOL_SIZE
If these parameters are set to a non-zero value they represent the minimum size for the pool. These minimum values may be necessary if you experience application errors when certain pool sizes drop below a specific threshold.
The following parameters must be set manually and take memory from the quota allocated by the SGA_TARGET parameter:
•     DB_KEEP_CACHE_SIZE
•     DB_RECYCLE_CACHE_SIZE
•     DB_nK_CACHE_SIZE (non-default block size)
•     STREAMS_POOL_SIZE
•     LOG_BUFFER

New features I like Oracle to include in Oracle Forms

I believe Oracle Form is the best tool to develop Database Application in Oracle Database. The weakness I see in Oracle Forms 10g may be its deployment as Java Applet. Java Applets are to be downloaded in the client browser, that's why it's not lightweight as PHP/ ASP/JSP scripting technology. So as a true web application it is not really handy.
Oracle provides JDeveloper/ Apex to accomplish that. But JDeveloper is very complicated to understand and Apex is rigid and you have little freedom on your user interface design, you cannot design a page as freely as you do in Adobe Dreamweaver for PHP. We as Form developer want oracle to develop a new development tool with following features:
1. Language will be PL/SQL.
2. There will be simple drag and drop interface design.
3. It will generate HTML/JSP page so that it can be light weight.
4. Provide a wide range of packages to accomplish javascripts/ajax while using PL/SQL language. Developer will just know what to do and by what technology javascripts/ajax, and accordingly invoke packages from withing PL/SQL editors.
5. Will have good old simple look in Form Development (JDeveloper is so complex and Apex is so shy in revealing it's features) while having same even better inner strength of developments.
6. Will require no client side tool like jinitiator or jre
7. Better and easy or even no use of web_util package but still accomplish file/image/spreadsheet access

Who/Where can i suggest new features/ changes

Hi Adobe Devs.
Are there someone i can message/mail new ideas, cause it sems
like this forum does not seem to be quite the right place.
I've been working with flash for some years (since flash4)
and i love the program. Honestly i think have some good ideas of
simple stuff that could be added to make the program easier to use,
both for designers and programmers.
I initially tried with this post:
http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=15&catid=194&threadid =1258827&enterthread=y
but noone has answered it...

there's a feature request list on adobe's site:
http://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
But you may have to wait at least another year unless your
wishes coincide with the features about
to be released in the CS3 version (days/weeks away).

List of new features, changes, and improvements from Designer ES2 to ES3 and then ES3 to ES4

I have been scouring the Adobe website and even contacted customer service for a list of all the changes made from Livecycle Designer ES2 to ES3 and then ES3 to ES4 with no luck. It seems like something basic that would be available. I am currently using ES2 and need to know if anything was changed or added to ES3 and then ES4 to see if it is worth the cost of upgrading. I do not use any of the other components of Livecycle and pretty much all the information on the Adobe website always goes back to those programs or how Designer works with those programs and it does not apply to me.
It is frustrating because it seems like Designer is an neglected stepchild of the ES Suite.

New features for OEM

How do I get new feature requests into oracle?
My main request, is an overhaul of the OEM homepage - Auto Refereshing set on, and geared more around the critical alerts and warnings, plus performance information. As it is there isn't a single page I can leave OEM on and get an up to date picture of our overall environment, without manually refreshing the home page and then navigating through several pages.
This gives me no excuse to ask for a plasma screen on the office wall, with OEM alerts on, amongst other important non-movie related items.
Edited by: user457649 on Oct 2, 2008 4:16 PM

Hi,
I am using the Dashboards in OEM to give an overview of the status and availability of our oracle environment and are using this dashboard on a screen on the wall. The dashboard will auto refresh.
First create a system which is a set of components that defines the system. I have 3 Oracle HTTP servers that I have defined as a system named 'HTTP System'.
Then create a generic service 'HTTP Services' and add the system you have just created. In this generic service you can define the availability and the service level rule.
Then go to the 'Reports' tab and mark the dashboard 'Services Monitoring Dashboard' and click 'Create Like'. Name your new report 'HTTP Dashboard', select 'Use the specified target' and go to the Elements tab.
Now click the 'Set Parameters' - Select the generic service 'HTTP Services' - click continue and then OK.
Open your report 'HTTP Dashboard'. This dashboard will show you the status and service level of the specified service and it will auto-refresh. If you want some performance and usage metrics on the dashboard you have to configure them in the generic service. When configuring performance and usage metrics it is also possible to define warning and critical thresholds and if the metric goes above the threshold you will be able to see that on the dashboard.
You can create more generic services and add them to you dashboard so that it eventually will give an overview of your environment.
Further information see the Oracle Enterprise Manager Concepts - Service Management.

10.1.3 EA: How do I get some of these new features to work?

I've read throughthis : Oracle JDeveloper 10.1.3 EA1 New Features
http://www.oracle.com/technology/products/jdev/101/collateral/101/1013eanewfeatures.html#Code%20Assist
I can't figure out how to get the following to work (I've searched the help and the forums):
- "JDK 5 loop: Converts for loops to use the new JDK 5 syntax."
That is listed under the "Code Assist" section.
Also, I can't seem to get Organize Imports and Reformat (what is this?) to work. Organize Imports worked well in the previous version of JDev 10.1.3 Preview but does nothing when I select it now. My imports remain unorganized :).
Thanks,
Chris

I enjoy having this thread conversation with myself. ;)
"Also, I can't seem to get Organize Imports and Reformat (what is this?) to work. Organize Imports worked well in the previous version of JDev 10.1.3 Preview but does nothing when I select it now. My imports remain unorganized :)."
OK, I figured out this problem, and it's interesting. If I go to Prefs -> Extensions and uncheck (turn off) Versioning Support 10.1.3.34.12, the "Organize Imports" and "Reformat" features no longer function. This is odd; what does Versioning Support have to do with code formatting? I turned off this extension because we use Subversion here and there is no plug-in for this yet. I'll leave it on since I desire these other, unrelated features.
My question about JDK 1.5 for loop code assistance still applies, though.
Thanks,
Chris

(V9I) ORACLE9I NEW FEATURE : LOGMINER 의 기능과 사용방법

제품 : ORACLE SERVER
작성날짜 : 2002-11-13
(V9I) ORACLE9I NEW FEATURE : LOGMINER 의 기능과 사용방법
==========================================
Purpose
Oracle 9i LogMiner 의 새로운 기능과 사용방법에 대해 알아보도록 한다.
(8I LogMiner의 일반적인 개념과 기능은 BUL. 12033 참조)
Explanation
LogMiner 는 8I 에서부터 새롭게 제공하는 기능으로 Oracle 8 이상의 Redo
log file 또는 Archive log file 분석을 위해 이용된다.
9I 에서는 기존 8I 에서 제공하던 기능을 모두 포함하고 그 외 새로운 점은
LogMiner 분석을 위해 dictionary 정보를 Flat file(output)로 생성이 가능하
였으나 9I 에서부터는 Flat file 과 함께 On line redo log 를 이용하여
dictionary 정보를 저장할 수 있게 되었고, Block corruption이 발생하였을
경우 해당 부분만 skip할 수 있는 기능이 추가되었다.
9I 에서의 New feature 를 정리하면 다음과 같다.
1. 9I New feature
1) DDL 지원 단, 9I 이상의 Redo/Archive log file만 분석 가능
     : V$LOGMNR_CONTENTS 의 OPERATION column에서 DDL 확인
2) LogMiner 분석을 위해 생성한 dictioanry 정보를 online redo 에 저장 가능
     : 반드시 Archive log mode 로 운영 중이어야 한다.
     : DBMS_LOGMNR_D.BUILD를 사용하여 dictionary file 생성
     : 기존 Flat file 또는 Redo log 에 생성 가능
     : 예) Flat file
          - SQL> EXECUTE dbms_logmnr_d.build
               (DICTIONARY_FILENAME => 'dictionary.ora'
               ,DICTIONARY_LOCATION => '/oracle/database'
               ,OPTIONS => DBMS_LOGMNR_D.STORE_IN_FLAT_FILE);
     예) Redo log
          - SQL> EXECUTE dbms_logmnr_d.build
               (OPTIONS => DBMS_LOGMNR_D.STORE_IN_REDO_LOGS);
3) Redo log block corruption 이 발생하였을 경우 corruption 된 부분을 skip하고 분석
     : 8I 에서 log corruption 발생 시 LogMiner 가 종료되고 분석 위해 다시 시도
     : 9I 에서는 DBMS_LOGMNR.START_LOGMNR 의 SKIP_CORRUPTION option 으로 skip 가능
4) Commit 된 transaction 에 대해서만 display
     : DBMS_LOGMNR.START_LOGMNR 의 COMMITTED_DATA_ONLY option
5) Index clustered 와 연관된 DML 지원 (8I 제공 안 됨)
6) Chained and Migrated rows 분석
2. 제약 사항(9I LogMiner 에서 지원하지 않는 사항)
1) LONG and LOB data type
2) Object types
3) Nested tables
4) Object Refs
5) IOT(Index-Organized Table)
3. LogMiner Views
1) V$LOGMNR_CONTENTS - 현재 분석되고 있는 redo log file의 내용
2) V$LOGMNR_DICTIONARY - 사용 중인 dictionary file
3) V$LOGMNR_LOGS - 분석되고 있는 redo log file
4) V$LOGMNR_PARAMETERS - LogMiner에 Setting된 현재의 parameter의 값
4. LogMiner 를 이용하기 위한 Setup
1) LogMiner 를 위한 dictionary 생성(flatfile or on line redo log)
2) Archive log file or Redo log file 등록
3) Redo log 분석 시작
4) Redo log 내용 조회
5) LogMiner 종료
5. LogMiner Example
1) flatfile이 생성될 location을 확인
SQL> show parameter utl
NAME TYPE VALUE
utl_file_dir string /home/ora920/product/9.2.0/smlee
2) dictionary 정보를 저장할 flatfile 정의 -> dictionary.ora 로 지정
SQL> execute dbms_logmnr_d.build -
(dictionary_filename => 'dictionary.ora', -
dictionary_location => '/home/ora920/product/9.2.0/smlee', -
options => dbms_logmnr_d.store_in_flat_file);PL/SQL procedure successfully completed.
3) logfile을 switch 하고 current logfile name과 current time을 기억한다.
SQL> alter system switch logfile;
System altered.
SQL> select member from v$logfile, v$log
2 where v$logfile.group# = v$log.group#
3 and v$log.status='CURRENT';
MEMBER
/home/ora920/oradata/ORA920/redo02.log
SQL> select current_timestamp from dual;
CURRENT_TIMESTAMP
13-NOV-02 10.37.14.887671 AM +09:00
4) test를 위해 table emp30 을 생성하고 update -> drop 수행
SQL> create table emp30 as
2 select employee_id, last_name, salary from hr.employees
3 where department_id=30;
Table created.
SQL> alter table emp30 add (new_salary number(8,2));
Table altered.
SQL> update emp30 set new_salary = salary * 1.5;
6 rows updated.
SQL> rollback;
Rollback complete.
SQL> update emp30 set new_salary = salary * 1.2;
6 rows updated.
SQL> commit;
Commit complete.
SQL> drop table emp30;
select
Table dropped.
SQL> select current_timestamp from dual;
CURRENT_TIMESTAMP
13-NOV-02 10.39.20.390685 AM +09:00
5) logminer start (다른 session을 열어 작업)
SQL> connect /as sysdba
Connected.
SQL> execute dbms_logmnr.add_logfile ( -
logfilename => -

endtime => to_date('13-NOV-02 10:39:20','DD_MON_RR HH24:MI:SS'), -
options => dbms_logmnr.ddl_dict_tracking + dbms_logmnr.committed_data_only)PL/SQL procedure successfully completed.
6) v$logmnr_contents view를 조회
SQL> select timestamp, username, operation, sql_redo
2 from v$logmnr_contents
3 where username='HR'
4 and (seg_name = 'EMP30' or seg_name is null);

OLAP 10GR2 new features/improvements?

Hello !
Could someone please describe the new features/changes in OLAP 10GR2 ?
There's no info available regarding OLAP, all i could find is that there are "dramatic improvements".

Thanks! but there's just a presentation with some graphs showing that performance is imporved, and some improvements named. I would like to see some kind of datasheet or dev guide describing more technical details, such as if I can still use my old Analytic Workspace or I will have to rebuild it to make use of new 10.2 fetures. But i must agree - the improvements are really impressive: for example "Running Batch Queries" is almost 5 times faster, ~33% less AW disk space usage, and "Processing Weekly Updates" compared to 10.R1 is 18 times faster. Wow! that's really a dramatic improvement !

When Oracle 11g new features 1z0-050 exam changed last time ??

Hi everyone,
Can anybody tell me that when the last time Oracle 11g new features 1z0-050 exam changed?? Does it changed recently, or its going to be change in near future??
Thanks and Regards,

Thanks and Regards,
Khurram1) Possible topic changes between beta and production.
2) When reviewed for 11gR2 rather than 11gR1 ... it is possible, but unlikely, there could have been minor topic changes.
3) IMHO It is unlikely this exam will have further topic changes from those currently shown on the exam page.
( Please note one other exam (117) has possibly recently had issues with not display all topics) ).
Suggest you give more reasons for your question before I will spend any time investigating further, i am pressed for time at the moment.Hi bigdelboy,
Thanks for quick reply. I am going to appear in this exam at this weekend. What basically I wanna ask is that the questions of this exam will be same as when one of my friends appeared 2 months ago?? , or the whole paper/questions could be changed this time ?? I know that the questions came randomly from a set of pool. So is there any possibility that the Oracle has been changed the whole set of pool of questions recently?

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.
