Automatic Storage Management :: Oracle ASM With Nimble Storage?
Mar 1, 2013My 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?

XML DB :: Dataload Into Different Storage
Oct 9, 2012I am an Oracle dba new to xml db,we have binary storage with 4schemas ,Right now indexing on 2gb table takes like 20GB on Path table and secondary xml index.

Right now i want to insert the data from old tables which had different URL . How I can improve performance without having 20Gb on secondary index objects.
Maxtor Shared Storage For RAC?
Aug 29, 2013In one of the book (Personal Oracle Real Application Clusters: Create Oracle 10g Grid Computing) I have seen the detailed explanation to configure Oracle 10g RAC on external disk- MAXTOR A01A200.
Is it possible to configure Oracle 11g Release 2 RAC with two node using MAXTOR disk?
or Is there any other external disk available which I can use it as a shared storage?

Jul 26, 2013Some shops run Oracle RAC using "conventional" storage, like emc, netapp, etc. Some shops run Oracle RAC using JBOD, just bunch of disks, all redundancy is managed by ASM.
How would you distinct these two approaches? JBOD approach sounds cheaper, so why serious enterprises are still using traditional conventional storage, like netapp and emc?

Indexing Changes Most Of The Blocks Of Database On Storage
Jun 20, 2011DB: Oracle 10g R2
OS: SUSE Linux SP 1 x864
We are maintaining a DR of our Database Server(oracle 10g R2 atop SUSE SP1 Linux) using Platespin(
[URL]......
Platespin is set to replicate(block based), incremental data(delta) every 1.5 hour from Production to DR site over a 30 Mbps dedicated fiber link.
Our maximum changes of data per day(during business hours) wont exceed 300 MB. During business hours Platespin replicates at least 1 GB at every replication cycle, while during off hours it replicates 300 to 500 MB per replication cycle. We are facing this strange issue with this box only(SLES 10 SP1 + Oracle 10g R2), we have protected MS Exchange 2007 Server based workloads without this strange issue, i.e in case of Exchange only delta replicates from Production server to DR site on Platespin.
Platespin support says us that Oracle re-indexes its database for better performance, so it is possible that re-indexing causes the blocks level changes on the storage, and since Platespin works on Block level, thats why it replicates so much(even though data is not changed that much)
here is actual words of Platespin support
<snip>
I think whenever Oracle database Indexing happens, it changes almost most of the Blocks of database and Platespin replicate all those Blocks.
As you know, Platespin checks the Date/Time attribute of every blocks before replication and if Date/Time attribute changes from last replication, it considers as changed block and replicate those blocks on Platespin Appliance. So, my suggestion is just look into the Oracle server behaviour before/after Data indexing process and do needful or do some workaround to overcome this issue.

is there anything we can do at oracle level ?
LOB - Storage - Reclaim Space In Database?
Jan 5, 2008I am having an issue with the LOBs in our Database. Our production DB is about 71G right now - if i do export/import using the DataPump - I see the data volume becomes 40G. I am sure its because of the LOBs in my Database. Our application uses lots of LOB datatype and I think the space is not being released.
The challenge is I cant do a full export/import in my Production DB as its a 24/7 system and to do export/import I need min. 5 hrs - which my business will not permit. I can I claim the unused space here. I have used Segment Advisor - but it has only given me 6G of space gain.
Is there any script I can try to use to reclaim space in the database.
Table Data Storage And Retrieval?
Apr 10, 2008Let 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.
SQL & PL/SQL :: How To Release Storage When Truncating Partition
May 27, 2012assuption is that when we truncate the partition it immediatly release the allocatd storage.i have just tested the scenario , but still i can see that table size is same even after truncating the partition( which have around 25% of the data)
alter table test truncate partition t1p3 update indexes ;
OR
alter table test truncate partition t1p3 drop storage update indexes ; to see the table size:
SELECT owner, table_name, TRUNC(sum(bytes) / 1024 / 1024) Meg
FROM (SELECT segment_name table_name, owner, bytes
FROM dba_segments

ASM VS Veritas Storage Foundation For Oracle RAC
Nov 16, 2012I am doing a Trade Study on Automatic Storage Management vs Veritas Storage Foundation for Oracle RAC on Solaris. I am trying to get feedback from individuals on which file system is best for a high OLTP 11gR2 system. I am really concerned about how the to file systems stack-up when compared on their overall performance. Our system admin doesn't trust ASM and is a firm believer in Veritas. I am trying to be objective and find the best solution for our projected upgrade system. We are upgrading from Solaris 890s to T4-2s, 11gR2, Solaris 10 or 11, and EMC storage. I was also concerned that Oracle doesn't have the ASMLIB package for Solaris. We have other system on Linux that use ASMLIB.

Properly Removing Old Temp Files From ASM Storage
Dec 16, 2010The other day, we had a query run amok in our 2-node production cluster. The 3 temp files for the temp tablespace were all still set to autoextend unlimited, something I forgot to change after a recent upgrade. I created 3 new temp files and tried to delete the huge temp files. I did this from sqlplus with this commad:
ALTER TABLESPACE PSTEMP DROP TEMPFILE '+DATA/isis/tempfile/pstemp.291.641298061';
The huge files are still in ASM storage. dba_temp_files reports that the status of them is AVAILABLE but they have no RELATIVE_FNO. Grid Control reports their status as OFFLINE and their size as 0. They are actually close to 20 GB each.
I tested the above alter statement in two test instances, also RACed with ASM storage and the temp files were successfully deleted, but they were much smaller in size. At this point, how do I delete the three 20GB files from ASM in our production instance? Why didn't they delete the first time?
Structure Handled In Physical Database Storage
Jun 18, 2012I have a question about Oracle schemas. Oracle schema is the user with its datase objects (table, index, eg) .In two different Oracle schemas, there can be two tables with same names. When the users connect to same Oracle instance they can access these tables with schema.tablename convention.
However, how is that structure handled in physical database storage. Are there two tables created with same name physically? I mean are these two tables with same name stored in different database files?
Implementation Of RAC To Non-RAC (Single Instance With Existing ASM-RAC As Storage)

Is it possible that we install a Single Instance to our DR-Site and used the copy of our ASM-RAC as storage?
Server Administration :: How To Change Default XML Storage
Sep 21, 2012As per the bellow the default XML storage has been changed in 11gr2.
docs.oracle.com/cd/E11882_01/appdev.112/e10492/whatsnew.htm
Quote:
Oracle Database 11g Release 2 (11.2.0.2) New Features in Oracle XML DB
The following Oracle XML DB features are new in Oracle Database 11g Release 2 (11.2.0.2).
Default Storage Model for XMLType
The default XMLType storage model is used if you do not specify a storage model when you create an XMLType table or column. Prior to Oracle Database 11g Release 2 (11.2.0.2), unstructured (CLOB) storage was used by default. The default storage model is now binary XML storage.
We have a application which works fine on r1 but not on r2 due to this change, we are going to investigate resolving the issue on the application in the future, in the mean time we need to be able to use the CLOB storage.
Does any one know where we can change this functionality back to the pre 11gR2 change?
