New Features of 10g

Any such list ??

There is a New Features manual on http;//tahiti.oracle.com. Robert Freeman also has an excellent book out on the new features.

10g New features

Hi all,
I have been asked to prepare a handbook on new features of 10g in developer's perspective. Can anyone suggest me where I could find it. B'coz most of the articales are written on DBA perspective and in bits not in full.
Thanks in advance.
Regards,
Jaggyam

Have you read this page? Although it's main focus is still on DBAs, I as a developer found the articles in there useful too.

FUNCTION-BASED INDEX ( ORACLE 8I NEW FEATURE )

제품 : ORACLE SERVER
작성날짜 : 2004-08-16
FUNCTION-BASED INDEX ( ORACLE 8I NEW FEATURE )
==============================================
SCOPE
10g Standard Edition(10.1.0) 이상 부터 Function-based Index 기능이 지원된다.
Explanation
1. 개요
 Function-based index는, 함수(function)이나 수식(expression)으로 계산
된 결과에 대해 인덱스를 생성하여 사용할 수 있는 기능을 제공한다.
 질의 수행 시 해당 함수나 수식을 처리하여 결과를 가져 오는 것이 아니라,
 인덱스 형태로 존재하는 미리 계산되어 있는 결과를 가지고 처리하므로
 성능 향상을 기할 수 있다.
2. 제약사항
1) aggregate function 에 대한 function-based index 생성 불가.
(예 : sum(...) )
2) LOB, REF, nested table 컬럼에 대한 function-based index 생성 불가.
3. 주요 특징
 1) cost-based optimizer에 의해 사용됨.
 2) B*Tree / bitmap index로 생성 가능.
 3) 산술식 (arithmetic expression), PLSQL function, SQL built-in
function 등에 적용 가능.
 4) 함수나 수식으로 처리된 결과에 대한 range scan 가능
 5) NLS SORT 지원
 6) SELECT/DELETE를 할 때마다 함수나 수식의 결과를 계산하는 것이 아니라
 INSERT/UPDATE 시 계산된 값을 인덱스에 저장.
 7) 질의 속도 향상
 8) object column이나 REF column에 대해서는 해당 object에 정의된
 method에 대해 function-based index 생성 가능.
4. 생성 방법
 CREATE [UNIQUE | BITMAP ] INDEX <index_name>
 ON <tablename> (<index-expression-list>)
 <index-expression-list> -> { <column_name> | <column_expression> }
 예) CREATE INDEX EMP_NAME_INDEX ON EMP (UPPER(ENAME));
 CREATE INDEX EMP_SAL_INDEX ON EMP( SAL + COMM, empno);
 * Function-based index를 생성하기 위해서는 QUERY REWRITE 권한이
 부여 되어 있어야만 한다.
 예) GRANT QUERY REWRITE TO SCOTT;
5. Function-Based Index 사용을 위한 사전 작업
 1) Function-based index는 cost based optimizer에서만 사용 가능하므로,
 테이블에 대해 미리 analyze 해 주는 것이 바람직하다.
 그리고 init 파일에서 OPTIMIZER_MODE 를 FIRST_ROWS 나 ALL_ROWS 등으
로 지정하거나 HINT 등을 사용하여 cost based optimizer가 사용되도록
한다.
 2) init 파일에서 COMPATIBLE 파라미터 값을 8.1 이상으로 설정되어 있어야
한다.
 ( 예 : COMPATIBLE = 8.1.6 )
 3) session/instance level 에서 QUERY_REWRITE_ENABLED 값이 TRUE 지정
되어 있어야 한다.
 ( 예 : ALTER SESSION SET QUERY_REWRITE_ENABLED = TRUE; )
6. 예제
 1) init 파라미터에서 다음과 같이 지정
 compatible = 8.1.6 (반드시 8.1이상이어야 한다)
 query_rewrite_enabled = true
 query_rewrite_integrity = trusted
 2) SCOTT 유저에서 function_based_index 생성
 create index idx_emp_lower_ename
 on emp
 ( lower(ename) ) ;
 3) EMP table analyze
 analyze table emp compute statistics ;
 4) PLAN_TABLE 생성
 @ ?/rdbms/admin/utlxplan.sql
 5) Cost based optimizer 선택
 alter session set optimizer_mode = FIRST_ROWS ;
 6) Query 실행
 explain plan set statement_id='qry1' FOR
 select empno, ename
 from emp
 where lower(ename) = 'ford' ;
 7) PLAN 분석
 SELECT LPAD(' ',2*level-2)||operation||' '||options||' '||object_name query_plan
 FROM plan_table
 WHERE statement_id='qry1'
 CONNECT BY prior id = parent_id
 START WITH id = 0 order by id ;
 -> 결과
 QUERY_PLAN
 SELECT STATEMENT
 TABLE ACCESS BY INDEX ROWID EMP
 INDEX RANGE SCAN IDX_EMP_LOWER_ENAME
7. 결론
Function-based index는 적절하게 사용될 경우 성능상의 많은 이점을 가져
온다. Oracle8i Designing and Tuning for Performance에서도 가능한 한
Function-based index를 사용하는 것을 권장하고 있으며, LOWER(), UPPER()
등의 함수를 사용하여 불가피하게 FULL TABLE SCAN을 하는 경우에 대해서도
효과적으로 처리해 줄 수 있는 방안이라 할 수 있다.
Reference Documents
-------------------

Partha:
From the Oracle8i Administrators Guide:
"Table owners should have EXECUTE privileges on the functions used in function-based indexes.
For the creation of a function-based index in your own schema, you must be
granted the CREATE INDEX and QUERY REWRITE system privileges. To create
the index in another schema or on another schemas tables, you must have the
CREATE ANY INDEX and GLOBAL QUERY REWRITE privileges."
Hope this helps.

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
regards
Arun

10G NEW FEATURE-HOW TO FLUSH THE BUFFER CACHE

제품 : ORACLE SERVER
작성날짜 : 2004-05-25
10G NEW FEATURE-HOW TO FLUSH THE BUFFER CACHE
===============================================
PURPOSE
이 자료는 Oracle 10g new feature 로 manual 하게
buffer cache 를 flush 할 수 있는 기능에 대하여 알아보도록 한다.
Explanation
Oracle 10g 에서 new feature 로 소개된 내용으로 SGA 내 buffer cache 의
모든 data 를 command 수행으로 clear 할 수 있다.
이 작업을 위해서는 "alter system" privileges 가 있어야 한다.
Buffer cache flush 를 위한 command 는 다음과 같다.
주의) 이 작업은 database performance 에 영향을 줄 수 있으므로 주의하여 사용하여야 한다.
SQL > alter system flush buffer_cache;
Example
x$bh 를 query 하여 buffer cache 내 존재하는 정보를 확인한다.
x$bh view 는 buffer cache headers 정보를 확인할 수 있는 view 이다.
우선 test 로 table 을 생성하고 insert 를 수행하고
x$bh 에서 barfil column(Relative file number of block) 과 file# 를 조회한다.
1) Test table 생성
SQL> Create table Test_buffer (a number)
2 tablespace USERS;
Table created.
2) Test table 에 insert
SQL> begin
2 for i in 1..1000
3 loop
4 insert into test_buffer values (i);
5 end loop;
6 commit;
7 end;
8 /
PL/SQL procedure successfully completed.
3) Object_id 확인
SQL> select OBJECT_id from dba_objects
2 where object_name='TEST_BUFFER';
OBJECT_ID
42817
4) x$bh 에서 buffer cache 내에 올라와 있는 DBARFIL(file number of block) 를 조회한다.
SQL> select ts#,file#,dbarfil,dbablk,class,state,mode_held,obj
2 from x$bh where obj= 42817;
TS# FILE# DBARFIL DBABLK CLASS STATE MODE_HELD J
9 23 23 1297 8 1 0 7
9 23 23 1298 9 1 0 7
9 23 23 1299 4 1 0 7
9 23 23 1300 1 1 0 7
9 23 23 1301 1 1 0 7
9 23 23 1302 1 1 0 7
9 23 23 1303 1 1 0 7
9 23 23 1304 1 1 0 7
8 rows selected.
5) 다음과 같이 buffer cache 를 flush 하고 위 query 를 재수행한다.
SQL > alter system flush buffer_cache ;
SQL> select ts#,file#,dbarfil,dbablk,class,state,mode_held,obj
2 from x$bh where obj= 42817;
6) x$bh 에서 state column 이 0 인지 확인한다.
0 은 free buffer 를 의미한다. flush 이후에 state 가 0 인지 확인함으로써
flushing 이 command 를 통해 manual 하게 수행되었음을 확인할 수 있다.

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.

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)
•     Flashback Database
•     Flashback Query Functions
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

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

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...

Does anybody know if Forms Developer 10g Release 2 (10.1.2) is any different from Forms Developer 10g (9.0.4)?
I wasn't able to find a document with new features.

I am sure the link was under your eyes ;o)

1Z0-045: Oracle Database 10g: New Features for Oracle 8i OCPs

Hi,
I was looking for right reference book for the 1z0-045 upgrade certification. I could not find any reference book that is related to this certification. Only one book have found out on Amazon site, which is "OCP Oracle Database 10g: New Features for Administrators Exam Guide (Oracle Press) (Paperback)" published by McGraw Hill.
But this book does not show exem number 1z0-045 anywhere. So I am not sure, is it a right book to buy.
Please let me know if any one has any knowledge about that.
I appreciate for your information.
Thanks
Amit

The book you mention is for those individuals who are upgrading their 9i OCP to the 10g OCP. Since you are apparently upgrading from 8i OCP, there is possibly a gap in your learning. You might want to take a look at OCP Oracle9i Database: New Features for Administrators Exam Guide (Paperback) which explains the new features for Oracle 9i to someone coming from an 8i background. No additional exam would be needed in your case but this book may help to fill out your knowledge a bit. You could also take a look at http://download.oracle.com/docs/cd/B10501_01/server.920/a96531/toc.htm if you would rather not buy an additional book.
