I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ?
2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well.
3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
I have to load data file into a table. And the requirement is as below:
Input Data:

3456|20130823|20130809|Siva 1234
The data should be inserted only in two rows as below:
When Value in first 3 fields is same, 4th field should be appended to the existing value in table.

I have Oracle 10.2.0.4.0 on RAC environment. I had 19 Data files on ASM. However one of my colleague has created new data file on a Node using Physical Drive which like this.

Now this file is in Recover State and when i try to make it online it says Block # 12 of this file is corrupted.

How to understand the two parameters db_file_name_convert and log_file_name_convert,if there are missing in the parameter file of standdy database,how does oracle will do?
View 3 Replies View RelatedI want to change dbname,sid,data/control file locations in operational dataguard setup i plan to follow as below
1)shutdown primary and standby (stop managed recovery)
2)change db name in init.ora of primary and standby change database name control file location
3)create control file for primary from trace(script) make changes for db name and file locations
4)mount and open primary database
5)create standby control file
6) transfer standby control file to standby
7) mount stand by database and start manage recovery
If this steps will error free do i need to follow any thing additional to this or what is other best way for this or its not possible at all
i did everything writen but when i do *SQL>alter database recover managed standby database disconnect from session;*
i go and look in the standby database AlertLog file ,and thats whats writen

strange thing that it realises the primary database in drive F and it goes to it but i dont understand what could be the reason of this ,although im doing this command while primary database is shutdown!
1) How to copy the ARCHIVED LOG FILE from Primary to DR location. Where if the DR is having the file already, how to SKIP that Particular Archived log file?
2) I have Checked with the FILE_TRANSFER DBMS package, but it gives the error if any file existing already.
I need a clarification on the below query.
I am having a Dataguard setup as Logical.
I am copying all the archive log files generated in the live server into the local server in order to apply into the Data Guard.
I am running a script for this process.
Question:How i can verify whether particular archive log file was applied into the data guard or not.
I wanted to make a script for applying the Archived log File in to DR by certain interval.
1) I will use the below view for finding the SEQUENCE so far applied.select sequence# from v$log_archive.
2) But how i can compare with the archive log files available in physical location with the above mentioned view.
eg:- the above view shows, the till the sequence 46789 is applied.And in the DR physical Location available sequences are 46795. which means 6 more archived log files are more, which are not applied into the DR so far.
I try to recover standby db from a primary db backup set,but the standby control file is different.
to create primary controlfile by rman:
backup control file format '/home/cur_control';
to create standby controlfile:
backup control file for standby format '/home/std_control';
I want to know if there is method to convert cur_control to std_control.
I am in need of a clarification regarding the file size growth in Physical Standby Database.Say we have 150 GB size of LIVE DB and we have created the same as in STDBY(150 GB).Will there be a growth in STDBY DB datafiles with respect to the LIVE DBOR only the logs are applied currently to the STDBY and the changes will only be reflecting when there is a switchover or failure scenario??

I am creating physical standby database through Rman duplicate command from 2 node rac cluster. rman do all its work. now am try to start the mrp process on physical standby database. I am getting following errors

and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
and that the SYS password is same in the password files.
returning error ORA-16191

I copied the same pass file from primary to standby and many times verify the same but i got the same error.
What is difference when you issue a create controlfile with "standby" keyword on the primary database
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';
vs. creating a control using
ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';
what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?
We have physical data guard configured version (10.2.0.4). We are in need to upgrade primary & standby database to 11G R2. Can we perform rolling upgrade.
View 3 Replies View RelatedControlling User Access to Tables in a Logical Standby Database can be controlled using the following command:

I am new to oracle which command do I use to set the file storage in oracle? I learnt the we have the option of specifying the storage pattern as per our queries.

I have a requirement wherein I have to migrate the data from one schema(source) to another(target).The source and target schema contains 50 tables each.For testing purpose two table are shown below
SOURCE>
DROP TABLE anchor;
CREATE TABLE anchor
(
anchor_idNUMBER(5),
angleNUMBER(5,2),
acad_colorVARCHAR2(20),
att_blkVARCHAR2(20)
);
[code]...
I'm able to migrate the data. On an average the each source table contains 50k to 1 lakh records.
We have two database servers(10g with OEL 5) to be clustered and two visible disk groups to each of those nodes. So question is can we choose only one disk group as a shared storage leaving the rest one as the redundant copy during database a creation window while installing the database. Because some of us argue that oracle database has a built-in capability to decide on what level of RAID we store our data.

View 2 Replies View RelatedMy organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?
Let me explain in detail. I have three tables
1. Emp Table: Columns-> EMPID and DeptID
2. Dept Table: Columns-> DeptName and DeptID
3. Team table : Columns -> Date, EmpID1, EmpID2, DeptNo.
There is a stored procedure which runs every day, and for "EVERY" deptID that exists in the dept table, selects two employee from emp table and puts them in the team table. Now assuming that there are several thousands of departments in the dept table, the amount of data entered in Team table is tremendous every day.
If I continue to run the stored proc for 1 month, the team table will have lots of rows in it.
The real problem is when I want to retrive data for a employee(empid1 or empid2) from Team table and view the related details like date, deptno and empid1 to empid2 from emp table.
How do we optimise the data retrieval and storage for the table Team. optimize the query and data retrieval time from Team table.
We are migrating database from HP to AIX. Data is all on SAN.I can do it through RMAN convert. What I want to know is if it is possible to move data at storage level without using Convert command?

Why there could sudden spike of demand on UNDO data in Active Data Guard ?

View 5 Replies View RelatedI am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.
