Rebuild Oracle 11g R1 clustered DB

I have oracle 11g R1 clustered(two nodes) on Linux boxes, with ASM. Now the cluster is down due to lost connection to SAN. We might not be able to restore the SAN the way as it was, meaning we lost all datafiles(diskgroup). I can not start cluster, asm and DB.
We have backup(rman and export) from production. I'm trying to find the best way to rebuild this clustered database.
Thank you for your help!

We have backup(rman and export) from production. I'm trying to find the best way to rebuild this clustered database.After setting up everything like, creating disk groups, You can go with two options. However you have backup of RMAN & EXPORT
1) export/import
You can create a RAC database using DBCA and then import the dumpfile.
2) RMAN.
You can restore the database on one node, later you can covnert this database as RAC

Clustering in Oracle 11g/10g

Hi
We have 40000 records in our database (Oracle 11g/10g), in which each record holds 2 to 3 images and so each record will be of some MBs.
Do we need to perform clustering to get a better performance?
Thanks

Thanks for the immediate replies.
We have a Windows 2003 Server, where in we have the Microsoft Visual Studio 2008 and Oracle 11g database.
Our web application will be developed using Microsoft Visual Studio 2008 having Oracle as backend.
At at time we are assuming 100 users to work with the web applications. We connect to the database everytime to display data in the web page.
100% performance is expected.
The Windows 2003 Server has a 4 GB of RAM. Is 4 GB enough to process these database requests or do we need more?

Oracle 11g: Oracle insert/update operation is taking more time.

Hello All,
In Oracle 11g (Windows 2008 32 bit environment) we are facing following issue.
1) We are inserting/updating data on some tables (4-5 tables and we are firing query with very high rate).
2) After sometime (say 15 days with same load) we are feeling that the Oracle operation (insert/update) is taking more time.
Query1: How to find actually oracle is taking more time in insert/updates operation.
Query2: How to rectify the problem.
We are having multithread environment.
Thanks
With Regards
Hemant.

Hi Nicolas,
Just a short explanation:
If you have a table with 1 column (let's say a number). The table is empty and you have an index on the column.
When you insert a row, the value of the column will be inserted to the index. To insert 1 value to an index with 10 values in it will be fast. It will take longer to insert 1 value to an index with 1 million values in it.
My second example was if I take the same table and let's say I insert 10 rows and delete the previous 10 from the table. I always have 10 rows in the table so the index should be small. But this is not correct. If I insert values 1-10 and then delete 1-10 and insert 11-20, then delete 11-20 and insert 21-30 and so on, because the index is sorted, where 1-10 were stored I'll now have empty spots. Oracle will not fill them up. So the index will become larger and larger as I insert more rows (even though I delete the old ones).
The solution here is simply revuild the index once in a while.
Hope it is clear.

[www.orbiumsoftware.com]Hmmm, index space not reused ? Index rebuild once a while ? That was what I understood from your previous post, but nothing is less sure.
This is a misconception of how indexes are working.
I would suggest the reading of the following interasting doc, they are a lot of nice examples (including index space reuse) to understand, and in conclusion :

Oracle 11G password case sensitive option is not working.

Hello,
I am facing problem in Oracle 11G. I installed and created a database. I disabled password case sensitive option by setting it to false (Pls see the below output). but case sensitive option is not disabled and i am not able to logon using the lower case password.
SQL> connect sys/<pwd in lower case>@<connect string> as sysdba;
ERROR:
ORA-01017: invalid username/password; logon denied
Warning: You are no longer connected to ORACLE.
SQL> connect sys/<pwd in uppper case>@<connect string> as sysdba;
Connected.
SQL> show parameter SEC_CASE_SENSITIVE_LOGON
NAME TYPE VALUE
sec_case_sensitive_logon boolean FALSE
Any idea.... should i open the case in the metalink ?
With Regards
Hemant Joshi.

Can you execute:
SQL> select USERNAME, PASSWORD_VERSIONS from dba_users where username = 'SYS';Have you tried reseting the sys password? When you create the password file by default the passwords stored on it are case sensitive, maybe you also need to rebuild it...

How to uninstall Oracle 11g Database Options?

I've come across a problem. A company that developed an application, installed Oracle 11g EE.
I guess they would use all default options. Some of them are licensed separately, and are not used. So I need to uninstall them.
For example, I see that it is installed "Advanced Compression". I tried to uninstall it from the Universal Installer, but there isn't an option.

Good news for my company.
There has never been used "Advanced Compression" and for everything else we are licensed.

Advaced compression in oracle 11g

Hi,
We are migrating databases from oracel 10g to 11g and we are using advance compression, i have few question please help me to understand
1. if i enable compression on tables is index also get compressed if not how i can enable compression on indexes
2.For table compression i will take the DDL of tables from oracle 10g databases and i create the tables in oracle 11g with COMPRESS FOR ALL OPERATIONS is this the right approach
Appreciated the inputs
thanks

Hi,
I checked for one of the table ALTER TABLE MOVE COMPRESS FOR ALL OPERATIONS after upgrading to 11g from 10g and rebuild the index
SQL> select index_name,COMPRESSION,STATUS from dba_indexes where table_name='POSITION_CUBE';
INDEX_NAME COMPRESS STATUS
TEST DISABLED VALIDstill compress column in dba_indexes show disabled
so i need to compress index also , how i can achive this
Thanks

Object Invalidation in Oracle 11g R2

Hi All,
I found a distinct behaviour in oracle 11gR2 which is not even available in previous releases . Let me explain with an example.
--creating a small table
create table TEMPSAMPLE (COL1 VARCHAR2(10),COL2 VARCHAR2(10),COL3 VARCHAR2(15),COL4 VARCHAR2(15));
-- Now Creating an Primary key index for table TEMPSAMPLE
ALTER TABLE TEMPSAMPLE ADD CONSTRAINT PKTEMPSAMPLE PRIMARY KEY (COL1,COL2);
---CREATING A VIEW ON THE ABOVE TABLE
CREATE OR REPLACE VIEW VWTEMPSAMPLE AS
SELECT * FROM TEMPSAMPLE;
-- CREATING A PACKAGE WHICH USES TEMPSAMPLE AND VWTEMPSAMPLE OBJECTS.
CREATE OR REPLACE PACKAGE PKGSAMP AS
VAL1 TEMPSAMPLE.COL1%TYPE;
VAL2 CONSTANT TEMPSAMPLE.COL1%TYPE:='11';
PROCEDURE VERIFYSAMP(INVAL IN NUMBER);
END PKGSAMP;
CREATE OR REPLACE PACKAGE BODY PKGSAMP IS
PROCEDURE VERIFYSAMP(INVAL IN NUMBER)
AS
VAL1 TEMPSAMPLE.COL1%TYPE;
VAL2 CONSTANT TEMPSAMPLE.COL1%TYPE:='11';
BEGIN
VAL1:='RAVI';
FOR RC IN (SELECT * FROM VWTEMPSAMPLE)
LOOP
DBMS_OUTPUT.PUT_LINE('COL1 '||RC.COL1);
DBMS_OUTPUT.PUT_LINE('COL2 '||RC.COL2);
DBMS_OUTPUT.PUT_LINE('COL3 '||RC.COL3);
END LOOP;
INSERT INTO TEMPSAMPLE VALUES('REC05','RAVI','EEE','CK');
DELETE FROM TEMPSAMPLE WHERE COL1='RECO1';
UPDATE TEMPSAMPLE SET COL4='CKR' WHERE COL1='RECO2';
DBMS_OUTPUT.PUT_LINE('VALUE IS '||INVAL);
DBMS_OUTPUT.PUT_LINE('VALUE IS '||VAL1);
END VERIFYSAMP;
END PKGSAMP;
--CREATING A PACKAGE PKGSAMP2 WHICH USES TEMPSAMPLE TABLE ITSELF
CREATE OR REPLACE PACKAGE PKGSAMP2 AS
VAL1 TEMPSAMPLE.COL1%TYPE;
VAL2 CONSTANT TEMPSAMPLE.COL1%TYPE:='11';
PROCEDURE VERIFYSAMP(INVAL IN NUMBER);
END PKGSAMP2;
CREATE OR REPLACE PACKAGE BODY PKGSAMP2 IS
PROCEDURE VERIFYSAMP(INVAL IN NUMBER)
AS
VAL1 TEMPSAMPLE.COL1%TYPE;
VAL2 CONSTANT TEMPSAMPLE.COL1%TYPE:='11';
BEGIN
VAL1:='RAVI';
FOR RC IN (SELECT * FROM TEMPSAMPLE)
LOOP
DBMS_OUTPUT.PUT_LINE('COL1 '||RC.COL1);
DBMS_OUTPUT.PUT_LINE('COL2 '||RC.COL2);
DBMS_OUTPUT.PUT_LINE('COL3 '||RC.COL3);
END LOOP;

END VERIFYSAMP;
END PKGSAMP2;
-- OBJECT STATUS OF PACKAGES
SELECT OBJECT_NAME,OBJECT_TYPE,STATUS FROM USER_OBJECTS WHERE OBJECT_NAME IN ('PKGSAMP','PKGSAMP2','VWTEMPSAMPLE');
OBJECT_NAME   OBJECT_TYPE STATUS*
VWTEMPSAMPLE     VIEW     VALID
PKGSAMP2     PACKAGE BODY     VALID
PKGSAMP2     PACKAGE     VALID
PKGSAMP     PACKAGE BODY     VALID
PKGSAMP     PACKAGE     VALID
Alter table TEMPSAMPLE DISABLE constraint PKTEMPSAMPLE KEEP INDEX;
DROP INDEX PKTEMPSAMPLE;
--OBJECT STATUS OF PACKAGES AFTER DROPPING INDEX
SELECT OBJECT_NAME,OBJECT_TYPE,STATUS FROM USER_OBJECTS WHERE OBJECT_NAME IN ('PKGSAMP','PKGSAMP2','VWTEMPSAMPLE');

PKGSAMP2     PACKAGE     VALID
PKGSAMP      PACKAGE BODY     INVALID
PKGSAMP     PACKAGE     VALID
Alter table TEMPSAMPLE ENABLE constraint PKTEMPSAMPLE;
As per the above process, if we observe that drop of index on a table arel lead to invalidation of view which* depends on that table and all the objects which uses this view will also get invalidated.*
The above invalidation is being occurred only in Oracle 11g R2, due to which we are facing the issue in our application.
We got a procedure where we disable a constraint , drop a index and process the insertion/updation into the tables. After successfull insertion/updation, at finally we are enabling the constraint.
This worked fine with previous releases of oracle 11g R2 , where as we recently migrated to 10g R2 which was leading to invalidation of all packages which uses the view , and in the application which uses previous db sessions are unable to access the invalidated package and raising an exception.
Please provide the solution if any possible

I tested the behavior in 10.2.0.4 and 11.2.0.3
In 10.2.0.4, The view was valid if we disabled the constraint using the keep index option but it became invalid after dropping the index. SO i guess you are making them as unusable and rebuilding them after data load.
in 11.2.0.3, The view became invalid as soon as we disabled the constraint using the keep index option.

Cannot post SD documents after upgrade to Oracle 11g

Dear Gurus,
Lately I have tried to upgrade database for SAP R/3 Enterprise 4.7 from Oracle 9i (9.2.0.7) to Oracle 11g (11.2.0.2). I have tried some of its features including table and index compression.
Right now my team is testing my server and find out some weird behaviour on its database. They try to create some sales order (VA01) and this action create SD document number. But when we try to check this created document number, SAP server replied weird message. It said that this SD document number is not on database and may have been archived.
When I check on ST22, it said "ORA-01502: index 'SAPWPR.VBAP~0' or partition of such index is in unusable state".
FYI, this index has been rebuild and compressed before.
I have tried to rebuild this index successfully, but still not help. I also have checked its status from SE11 and I cannot find this index on VBPA table.
Any suggestion ?

Export and Import issue in Oracle 11g

Hi All,
I have exported data using exp command in oracle 11g by keeping deferred_segment_creation FALSE.
Even then my zero records tables are not coming in export.
What could be the reason or what other thing i have to do to make it work.
Thanks in advance
Mohsin J

Tables that were created before you changed deferred_segment_creation to FALSE and do not have any rows would still be segment-less tables --- i.e. not exported.
You need to issue an "ALTER TABLE tablename MOVE" for each of such tables (after having set deferred_segment_creation to FALSE) to force a rebuild of these tables with segments before the export.
Thus, the sequence is
1. set deferred_segment_creation to FALSE
2. identify all tables with 0 rows
3. issue an ALTER TABLE tablename MOVE for each of such tables from step 2
4. Re-run your export
alternatively use conventional export (exp) instead of datapump export.

Hi
I altered the table in Oracle, I add the primary key:
alter table emp add constraint

Oracle 11g special character(á) length count

Hi Experts,
I'm facing an issue while inserting the special character (á) in Oracle 11g. The database table length for the column 'descr' declared as varchar2(30). I'm inserting a string ('Aabbccee/ddffggh Ffrán y Plaos') in column descr which is having the length 30. Please note the character 'a' in Ffrán is not letter 'a' but special character *'á'*. It gives the below error,
java.sql.SQLException: ORA-12899: value too large for column ""DESCR" (actual: 31, maximum: 30)
The strange is the same query works/insert in Oracle 9i without any issue. I suspect the special character *'á'* will take/count as 2 character in Oracle 11g but single character in Oracle 9i.
Please provide the insight views and solution for this issue with out altering the column length.
I hope the solution at the earliest, since this is an urgent requirement.
Thanks.

Your 9i database has character set WE8ISO8859P1 which is a single byte characterset.
But on 11g, you're using AL32UTF8 - a multi-byte unicode characterset.
Obviously with a multi-byte characterset, characters which took up a single byte might now need multiple bytes.
So the default meaning of VARCHAR2(30) which is VARCHAR2(30 BYTE) may not be sufficient to hold 30 characters.
Assuming that you want to use the different characterset - (and if not then you might as well rebuild your 11g database with the 9i characterset), then you need to do is to change your LENGTH SEMANTICS to CHAR not BYTE.
This means two things.
1. Changing NLS_LENGTH_SEMANTICS to CHAR via ALTER SYSTEM. I believe this needs a restart to take effect. This will affect newly created column definitions so that VARCHAR2(30) means VARCHAR2(30 CHAR) not VARCHAR2(30 BYTE) - so for changes going forward.
2. Changing existing column definisition via ALTER TABLE xyz MODIFY colname VARCHAR2(30 CHAR) etc.

Oracle 11g r2 report server on vmware esxi 5.1

dear gurus
assist me we are facing issue with oracle 11g r2 report server on vmware esxi 5.1

where it is on windows 2008 r2 sp1
our vendor say not certify by oracle this product, we have no rac just standalone env
1db 1 form 1 report server all on VMs guest working
we could not find os vm oracle logs root causes
kindly assist or advise

Is this possible to do - so I can learn about Oracle 11g R2 RAC operation, tuning, setup and maintenance?Yes, possible to setup.
No, you are unlikely to learn anything of value ito tuning and maintenance as the environment does not run on actual cluster h/w that are used in real world RAC clusters. For example, huge pages, jumbo frames - pretty meaningless in a VM for tuning Oracle RAC. Bonding of Interconnect Interfaces and pulling the plug - pretty much useless. What about running multiple I/O paths to the cluster's storage server? Using RDS for Interconnect instead of UDP? Etc. Etc.
RAC is only as performant, scalable and robust as the h/w components it is build on. I cannot see any value in virtualising this and expecting to gain real insight to RAC performance management and tuning. Best one can expect is familiarisation with installation prerequisites, the installation steps and setting up the database. I question if any more value than that can be obtained from a single PC virtualised RAC environment.

Oracle Real Application Clusters

hi all
i am using oracle database 11g Release2 and Oracle Linux enterprise edition.
can anyone guide me why we need to use Oracle Real Application Clusters and plz
guide me how to install or configure all these?
and someone told me we needed 10Gb Gigabyte Ethernet.
how to go for 10GB by using LoopBack?
i am using vertualbox and i checked the loopback is only 1GB so how to go for 10GB
i posted my thread here
Oracle Real Application Clusters
but someone suggested me to for this forum so i posted here.
so if i am wrong plz forgive me.

Moreover, I've a step by step RAC installation guide on vmware, but it's for 10gR2. However, you can check it and have a basic knowledge of the main steps

CRS not starting after Oracle 11g Grid was succesuflly installed

Hi:
Have 2 node RAC. My Shared storage is on openfiler.
Oracle 11g Grid was successfully installed and all the services was working fine. When i restarted the system I found CRS was not coming up. Remaining processes were up and running.
Let me explain what I did: (O/s RHEL 5.4 & oracle 11g R2 grid)
I have a partition in shared disk /dev/sdc1 (I have other partitions, but thought of using only one for OCR and voting disk). (did not define it as raw partition as I used to do in 10g RAC).
While installing Oracle grid and when it prompted to enter the Diskgroup for OCR and Voting disk I gave a name DGDATA and choose only one (external redundancy) disk “/dev/sdc1″ (it does not ask for one for OCR and one for Voting as it used to do in 10g clusterware installation). As per my assumption both OCR and Voting disk were created within /dev/sdc1 (after installation when I queried I got the same info)
The Oracle grid installation has gone through successfully. when I restart the system I find CRS not starting.
The log says: “Error PROC:26: Error while accessing the physical storage ASM……..
ORA-01034: oracle not available...
Could not init OCR, code:26….
Linux permission denied".
For your information….ASM instance is up (check in both the nodes) and I find the diskgroup mounted.
Can anyone help on this.
Also let me know how to uninstall Oracle 11g Grid software and configuration. If I have to reinstall the Oracle 11g grid software and config once again is it possible without reinstalling RHEL. Let me know the steps or any link please. don't want to get into a mess again.
Thanks in advance.
Regards
Dinesh

Jorg, I even tried to nomount the DB instance using initDBRAC.ora pfile. Then tried to create spfile still got the same error.

Listner issues in Oracle 11g server installation

Hi,
I am facing problem while connecting to Oracle 11g server on 'Windows 7 Enterprise edition - 32 bit OS'.
I have successfully installed Oracle 11g server on Windows & enterprise machine.
Listener and TNSnames.ora files are fine. But I am not able to connect through Oracle client machine. it shows 'TNS: Could not resolve the service name'.
When I check the listener status on the server, it shows the service ABBPROD is READY, but still not able to connect through client machine. I have gone through many similar threads and tried out the solutions provided but the problem still exists. Few of the things I tried are as below.
1. I have tried changing the ORACLE_SID and setting the $ORACLE_HOME parameter.
2. Tried replacing the HOST as 'localhost' to system IP address/computer name
3. Listener stop and start
4. Service stop and start
5. Checked the firewall settings of the server machine
I shall paste the listener.ora and tnsnames.ora files below.
