Oracle Database Partitioning Feature on Azure VM

Hi,
we would like to know if Oracle Database partitioning feature is available and activable on Azure virtual machine with Oracle pre-installed database instance.
Thanks

Hi,
Oracle Database 11g R2 EE with Advanced Options includes Partitioning.
Create a virtual machine from here:, check this link:

Oracle Exchange partition feature not working as expected?

I used the Exchange Partition feature to swap segments between 2 tables- one Partitioned, and one Non-Partitioned. The exchange went well. However, all the data in the partitioned table has gone to the partition which stores the maxbound values.
Any ideas if this is the default behavior or have i missed out something?
/** actual table names changed due to client confidentiality issues */
-- Drop the 2 intermediate tables if they already exist
drop table ordered_inv_bkp cascade constraints ;

1st create a Non-Partitioned Table from ORDERED_INV and then add the primary key and unique index(s):

That isn't possible. The data in the partition before the exchange could only have gone to the non-partitioned table.

Oracle database product feature matrix

Hi,
1)I just went through the doc http://www.oracle.com/us/products/database/039449.pdf. But it does not mention which feature requires additional license and which one comes by deafault. Can anyone give me link of a doc which mentions whether additional license required or not for a particular feature at a particular edition?
2)*Is there any such separate doc for RAC database features?*

DATABASE RESOURCE MANAGER ( ORACLE 8I NEW FEATURE )

제품 : ORACLE SERVER
작성날짜 : 2004-08-16
DATABASE RESOURCE MANAGER ( ORACLE 8I NEW FEATURE )
===================================================
SCOPE
8i~10g Standard Edition 에서는 Database Resource Manager 를 지원하지 않는다.
Explanation
Database Resource Manager란 OS에서 제공하는 자원 (예 : CPU 자원 )에 대해 DB
차원에서 계획을 세워, 세부 관리를 할 수 있도록 해 주는 서비스이다.
예를 들어 주간에 batch 작업을 처리하더라도, OLTP 업무에는 지장을 주지 않아야
할 경우 batch 작업에 CPU 자원을 적게 할당해 주는 것이 바람직 하며, Resource
Manager를 활용하여 CPU 자원을 batch 작업과 OLTP 업무에 서로 다르게 할당해 줄
수 있다. ( Oracle 8.1.6 까지는 Resouurce Manager에서 CPU 자원에 대해서만
관리만 가능하다 )
1. 용어
1) Resource Consumer Group
사용자 session들의 집합. Resource에 대한 요구사항에 따라 나뉘어진 그룹.
2) Resource Plan
     Consumer Group에 자원을 할당 해 주기 위한 resource plan directive들을
포함.
3) Resource Allocation Method
     Resource Manager에서 자원을 할당해 주는 방법/정책.
4) Resource Plan Directive
     Resource Plan에 대해 자원을 할당해 주는 세부 내역.
2. Resource Consumer Group
* 기본 group
     [ 사용자가 삭제, 수정할 수 없는 group ]
     OTHER_GROUPS : active plan schema에 속하지 않는 consumer group의 모든
session
     DEFAULT_CONSUMER_GROUP : consumer group을 지정하지 않은 모든
session.(default)
     [ 기본적으로 제공되나 사용자가 삭제하거나 변경할 수 있는 group ]
     SYS_GROUP : SYSTEM_PLAN에 대한 high priority consumer group
SYSTEM, SYS user에 할당한다.
     LOW_GROUP : SYSTEM_PLAN에 대한 low priority consumer group
3. Resource Plan
     Consumer group에 속하는 session들은 해당 group에 대한 resource plan에
따라 자원 할당이 결정되며, 자원 할당에 대한 세부 사항은 resource plan에
대한 resource plan directive에서 지정된다.
     Resource plan은 subplan을 둘 수 있다.
4. Resource Allocation Method
     Round-robin Method : Consumer group 내에서 session들에 대한 CPU 할당
     Emphasis Method : Consumer group에 할당되는 CPU
     Absolute Method : Parallel degree 한계 ( 예 : Parallel Query에서의
degree )
5. Resource Plan Directive
     Resource Plan Directive에 지정된 내용들은 resource plan에 따라
consumer group에 자원을 할당할 때 반영된다.
6. 구현 예제
     MYDB PLAN +-> MAILDB PLAN +-> POSTMAN GROUP (40% Level 1)
     | (30% Level 1) |
     | +-> USERS GROUP (80% Level 2)
     | |
     | +-> MAILMAINT GROUP (20% Level 2)
     | |
     | +-> OTHER GROUP (100% Level 3)
     |
     +-> BUGDB PLAN +-> ONLINE GROUP (80% Level 1)
     (70% Level 1) |
     +-> BATCH GROUP (20% Level 1)
     |
     +-> BUGMAINT GROUP (100% Level 2)
     |
     +-> OTHER GROUP (100% Level 3)
     위 예에서 MYDB PLAN에는 2개의 subplan ( MAILDB PLAN, BUGDB PLAN )이
     있으며 각각 30%와 70%의 CPU 자원을 할당하였다.
     Level 1, Level 2, Level 3 는 우선순위 레벨을 의미하며, 하나의
     resource plan에서 동일한 level의 합이 100%를 넘지 못한다.
     ( Level 은 1부터 8까지 지정할 수 있으며 level 1이 가장 우선순위가
     높으며 level 8이 가장 우선순위가 낮다 )
     예를 들어 전체 CPU 자원의 70%를 할당 받은 BUGDB PLAN은 다시
     ONLINE GROUP과 BATCH GROUP을 두고 있는데, 이 둘의 Level이 모두 1이며
     두개의 percentage의 합이 100%이다. 하지만, 즉, level 1인 ONLINE GROUP
에 90%를 할당하였다면, level 1인 BATCH GROUP에는 10% 이상을 할당할 수
없다.

7. CONSUMER GROUP에 사용자나 세션을 할당하는 방법
     먼저 인스턴스에서 사용할 TOP Level resource plan 을 지정한다.
initSID.ora에 RESOURCE_MANAGER_PLAN = MRDB_PLAN 지정이나 아래와 같이
session level에 ALTER SYSTEM command를 사용하여 지정한다.
     ALTER SYSTEM SET RESOURCE_MANAGER_PLAN = MYDB_PLAN;
     그리고 SCOTT 계정에 BUG_ONLINE_GROUP과 BUB_BATCH_GROUP 에 속할 수 있는
권한을 부여
DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP ('SCOTT',
'BUG_ONLINE_GROUP', TRUE);
     DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP ('SCOTT',
'BUG_BATCH_GROUP', TRUE);
     * DBMS_RESOURCE_MANAGER.SET_INITIAL_CONSUMER_GROUP( user in
varchar2, consumer_group in varchar2);
     예)
     DBMS_RESOURCE_MANAGER.SET_INITIAL_CONSUMER_GROUP('SCOTT',
'BUG_ONLINE_GROUP');
     SCOTT 계정을 BUG_BATCH_GROUP에 할당
     * DBMS_RESOURCE_MANAGER.SWITCH_CONSUMER_GROUP_FOR_SESS (
                         session_id IN NUMBER,
                         session_serial IN NUMBER,
                         consumer_group IN VARCHAR2);
     예)
     DBMS_RESOURCE_MANAGER.SWITCH_CONSUMER_GROUP_FOR_SESS( 11, 2,
'BUG_ONLINE_GROUP');
     * DBMS_RESOURCE_MANAGER.SWITCH_CONSUMER_GROUP_FOR_USER (
                         user IN VARCHAR2,
                         consumer_group IN VARCHAR2);

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.

IZo-045 Oracle Database 10g DBA New Features for Oracle8i OCPs exam

I am preparing for IZO-045 Oracle Database 10g DBA New Features for Oracle8i OCPs exam, wanted to know in order to pass the exam,
Is it enough to read the exam topics mentioned on the following webpage.

Muhammad AliOkay I've haven't done 1z0-045 ... but I at one point I was considering 1z0-050 so I'm willing to share my views on an upgrade exam and exams in general.
Remember Oracle are trying to ensure that a DBA who was tested at 8i DBA OCP has nw
It depends on your definition of read the topics. If you mean literally just read the topics then that will result in a failure. If you mean study research practice and fully understand the topics that should lead to a pass.
Bear in mind that Oracle would expect a competent 8i DBA attending the 5 day training course Oracle Database 10g: New Features for Oracle8i DBAs [http://education.oracle.com/web_prod-plq-dad/plsql/show_desc.redirect?dc=D17389GC10&p_org_id=&lang=&source_call=] to be able pass the exam with perhaps 2 to 4 weeks further study, revision and practice.
Interestingly this particular exam has a relatively high pass mark (73%) ... one implication of that is that it is prudent to be comfortable with all topics.
Generally an upgrade exam will cover topics beyond that of the straight OCA/OCP exams. The questions will obviously be at OCP level.
It is possilble the Sybex book Oracle 10g New Features for Administrators Study Guide (Certification Study Guide) ISBN-13: 978-0782143553 which although for 1z0-040 may have some relevance for some of your topics. If you choose to purchase it that is your choice. (It seems to have good amazon reviews ... though all of these books can contain errors, it may or may not be updated for 10gR2, and some Sybex Oracle books are sometimes OTT in some areas IMHO, but that wouldn't stop me using one).

http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABJFHED
Some of the features you are quoting are difficult to check because they are not exactly named this way in the licensing guide.
For example Monitoring and Tuning the Database is not precise enough.
AWR and ADDM need Tuning Pack or Diagnostic Pack which are only available with Entreprise Edition.

I suppose that is nice.
It would be even nicer if the drivers actually conformed to JDBC so that one could for example reliably use blobs in a J2EE server with CMP.

How to migrate Azure SQL Codefirst DB to Oracle database?

Hi,
we have been developing a Web application with Windows Azure Code first SQL DB using Code first approach.
In the future we want to migrate our Azure SQL Code first DB to Oracle. If we migrate it to Oracle, does the application works fine? or do we need to do any additional actions in migrating from Azure SQL Code first db to Oracle DB?
It would be great if anyone provides me complete information on this.

Hi,
You should be able to move the Azure SQL Code First Database to Oracle Database. You will have to make minor changes, for e.g connection string.
Please have a check on the below link which talks about using Entity Framework 6 Code First with Azure SQL database as a backend. It will give you an idea on how to approach your migration.

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.

Migration Oracle 9iR2 - Oracle Database 10g Express Edition, please, help

Good day!
Now I study examples from tutorial book "Oracle 9iR2 Data Warehousing"
(translated to Russian) written by Lilian Hobbs, Susan Hilson, Shilpa Lawande. However my Oracle is "Oracle Database 10g Express Edition" and ( as I thought ) for this reason I can't perform these examples.
Please, help me, if it no hard.
First example founded on using "Oracle Database Configuration Assistant"
and "Oracle Enterprise Manager Console". However, I not found them at
"Oracle Database 10g Express Edition".
Now I use only "Oracle Application Express" ( and SQL ). Please, tell me,
if "Application Express" has enough functionality with comparision to
"Oracle Database Configuration Assistant" and "Oracle Enterprise Manager Console"
and how I need to do ? (It must, because 10 > 9)
Second example founded on using SQL. First 80% SQL-commanfs of this executed succesfully. But command "CREATE TABLE easydw.purchases" has error message
"PARTITIONing is not available." Really, in "2 Day Developer Guide"
(SQL Reserved Words ) PARTITION is not exist.
Can I CREATE TABLE easydw.purchases by "Oracle Database 10g Express Edition"
(with PARTITIONing by other means of SQL )?
There is full text of this SQL-Command:
CREATE TABLE easydw.purchases
(product_id varchar2(8)
constraint not_null_product_id NOT NULL
constraint fk_product_id
REFERENCES product(product_id),
time_key date
constraint not_null_time NOT NULL
constraint fk_time
REFERENCES time(time_key),
customer_id varchar2(10)
constraint not_null_customer_id NOT NULL
constraint fk_customer_id
REFERENCES customer(customer_id),
purchase_date date,
purchase_time number(4,0),
purchase_price number(6,2),
shipping_charge number (5,2),
today_special_offer varchar2(1)
constraint special_offer
CHECK (today_special_offer IN ('Y','N')) )
PARTITION by RANGE (time_key )
partition purchases_jan2002
values less than (TO_DATE('01-02-2002', 'DD-MM-YYYY'))
pctfree 0 pctused 99
storage (initial 64k next 16k pctincrease 0)
tablespace purchases_jan2002,
partition purchases_feb2002
values less than (TO_DATE('01-03-2002', 'DD-MM-YYYY'))
pctfree 0 pctused 99
storage (initial 64k next 16k pctincrease 0)
tablespace purchases_feb2002,
partition purchases_mar2002
values less than (TO_DATE('01-04-2002', 'DD-MM-YYYY'))
pctfree 0 pctused 99
storage (initial 64k next 16k pctincrease 0)
tablespace purchasee_mar2002 );
Naturally, I also shall continue try find solution.
Winni.

Winni,
Partitioning is only available with Oracle Enterprise Edition.
Here is a list of features by edition:
http://www.oracle.com/database/product_editions.html
DBCA is not needed with Express edition because you can only have one XE database per server, and all options are pre-configured.
Enterprise Manager Console is not included with XE - only with the other editions.
You can get most of the functionality through SQL, Application Express and SQL Developer.
