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)

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 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.

How to use Oracle 10G SQL features in OWB?

We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
Oracle 10G SQL offers
1) Inserting Into a Table with Error Logging
2) conditional_insert_clause, Specify the conditional_insert_clause to perform a conditional multitable insert.
Did anyone use above features in OWB10G mapping?
How do we use them?
Thanks in advance.
RI

Hi,
Just a thought on the multi-table insert. OWB generates multitable insert when one source is mapped to multiple targets only on the condition that after the splitter there should not be any OWB operator that can change the cardinality of the row-set coming out of the splitter (like joiners, filters, aggregators etc.)..
Regarding the link, I was wondering where I could find a decent documentation of the shadow table and the DML Error Logging through OWB .. Thanks for the link.
OWB error messages are basically Oracle Error Messages when you consider the code that gets deployed. Other than that VLD errors are sometimes mysterious and hard to debug.. Hope someone can give us more details on how to handle such VLD errors :)

Oracle 10g Editions

I want to buy Oracle 10g Standard Edition One for a my software that is to be installed in a big government department. The database will reside in one or two servers and the client part will run on more than 30 nodes. I want to know whether Standard Edition One supports the number of client nodes I desire.

Try calling your Oracle rep and discuss the requirements and so on. Licensing related info can be found via following links:

Oracle 11g R2 Edition feature

Hi All,
I am trying out the Oracle 11gR2 edition feature .Can any one please give me a hand on how to make a particular edition available to a set of users.
I understand that one way is ALTER SESSION SET EDITION = <edition_name> but that applies to current session alone.
The other way is to ALTER DATABASE DEFAULT EDITION = <edition_name> but this will make the new edition available to all users.
What I need is to make available old edition to a set of users and the new editions to another set of users or to be simple how to link user to a particular edition and make that edition available only to that user.
Thanks in Advance.

Create a Logon Trigger.
For example :
create or replace trigger logon_set_edition
after logon on database
when (user = 'HEMANT')
begin
execute immediate 'alter session set edition=HEMANT_EDITION ';
end;

Oracle 10g R2 - Metadata Issue With Version Controlled Resources

We are trying to utilize the Oracle 10g R2 feature that allows user-defined metadata to be attached to XML DB resources. However, we are encountering errors when we try to append/attach metadata to a version-controlled resource (VCR). The following steps were followed:
1. Register a new schema to be used for metadata (XMLSCHEMA.registerSchema).
2. Add a new resource to to the XML DB and make it version controlled (DBMS_XDB.createResource and DBMS_XDB_VERSION.makeVersioned).
3. Checkout the newly created version-controlled resource (DBMS_XDB_VERSION.checkout)
4. Add metadata to the version-controlled resource (DBMS_XDB.appendResourceMetadata)
However, after step 4, the errors shown below are encountered:
========================================================
begin
ERROR at line 1:
ORA-00600: internal error code, arguments: [qmxStrCopy: INLOB 2], [], [], [],
ORA-06512: at "XDB.DBMS_XDB", line 890
ORA-06512: at line 2
========================================================
The steps followed for adding metadata to a resource were taken from Chapter 26 of the "Oracle XML DB Developer's Guide 10G Release 2" (http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb_repos_meta.htm#sthref2302).
Is is possible to append and maintain metadata to an XML DB version controlled resource (VCR)? If so, what are the correct steps to do this? Note that if this is tried with a resource that is not version controlled, then no errors are encountered.
Thanks,
Steve

It appears that this issue has been solved in the next release of the database

Disconnected from Oracle Database 11g Enterprise Edition Release 11.1.0.0.0 - Alpha
With the Partitioning and Data Mining options
I've filed bug 5313655 for the 10.2.x behavoir. If this is important to you you might want to consider signing up for the forthcoming beta program for the next release of the database

Oracle 10g Standard One

I want to clear out some issue abt Oracle 10g Standard One and Partitioning. On the internet I have found that one of the Oracle Enterprise Edition Features not available in Oracle Standard Edition One is:
Oracle partitioning - For database over 100 gigabytes
Can someone confirm this? Does it actually mean that there is actually PARTITIONING in Oracle10g Standard One if the database is less than 100GB ?
thanks

I don't believe partitioning is available in the standard edition (or in Standard Edition One). The comment you refer to is likely explaining the sort of databases that might benefit from partitioning-- there aren't a lot of folks that would want to partition database tables if the database was only a few GB in size.

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.

Oracle9i/Oracle 10g OCA certification

I have worked on Oracle 9i database and i have basic knowledge about Sql commands and i am planning to go for Oracle 10g Certification does it make any difference if i do not take ORACLE 9i Certification and directly go on to do my Oracle 10g Certification .
Help Me

You are very much eligible for writing Oracle 10g OCP, even if you have experience in Oracle 9i. What you can do is, read the Oracle 10g New Features, and then you will have both Oracle 9i & 10g knowledge.
Best of luck.
