Step for oracle database storage migration

Hi all
Need a help for database storage migration from old storage to new storage. Please advise and given step to migrate the database storage.
Database version: 9i,10g(ASM),10g and 11g (ASM)

Hi;
Your question is not clear. Migration from what to what?

What kind of storage we should use for oracle database?

Hi
thank you for reading my post
Can some one please explain what kind of hardware storage is common for oracle database, and kindly please provide some explanations about the reason that we can use such storage?

Perhaps you're thinking about RAID, an acronym for Redundant Array of Inexpensive Disks? That's not specific to Oracle by any means, it's a very common way of setting up multiple disks in a server so that the failure of one or two disks doesn't cause the system to lose any data. If you're dealing with a server of any size or any sort of SAN or NAS device, it is going to use RAID, the question is which form of RAID (there are different sorts of configurations with different levels of cost, performance, and durability).

When I increase storage for Oracle database

Hi, Gurus
We start and golive SAP one year ago, Now
my oracle databes usage is 68% like below from ST04.
Size: 308.09 GB Total size: 400.39 GB 
Free Size: 97.27 GB Total free size: 189.57 GB 
Used: 68 % Total used: 53 % 
This storage usage at UNIX level 
/dev/vx/dsk/eccprd-dg/sapdata1 100G 72G 26G 74% /oracle/PRD/sapdata1 
/dev/vx/dsk/eccprd-dg/sapdata3 100G 80G 19G 82% /oracle/PRD/sapdata3 
/dev/vx/dsk/eccprd-dg/sapdata4 100G 68G 30G 70% /oracle/PRD/sapdata4 
/dev/vx/dsk/eccprd-dg/sapdata2 100G 89G 10G 90% /oracle/PRD/sapdata2 
When I must increase storage size because it to much usage 90% ?
Or wait 90++ % all drive.
Thank for all comment.

Hi Witoon,
What you need to do for monitoring space for oracle Database is to proactively monitor tablespaces of the databases.
This can be easily done with the help of BRtools . It is safe to keep the used tablespace < 85 % to avoid any kind of tablespace issues. If any major loading process is to started then the free space of the table space should be adjusted accordingly.
Out of several tablespaces present in the Oracle DB few are made by Oracle for example
SYSTEM
PSAPUNDO
SYSAUX
PSAPTEMP
TOOLS
Leaving the above mentioned tablespaces you need to monitor the tablespaces whose sizes are changing.
When you increase the size of the tablespace then more space is allocated on the disk in the form of datafile for that tablespace so before increasing the size of the tablespace you need to check the free space on the disk
Use df -h (Linux command) for checkin the diskspace on linux server.
Thanks

Configure Xiotech storage for Oracle database

Our db is 10.2.0.3 RAC db with 2 nodes of MS Window 2003 servers. We just purchased a new storage Xiotech Emprise 7000 for database usage and I would like to get any information related how to better configure this kind of storage for Oracle database. Such as how big the logical volumes should be and how many disks you be included in them?
Thanks a lot for your input,
Shirley

Since you are using RAC, you'd better configure storage to use ASM.
Using Automatic Storage Management
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/storeman.htm#ADMIN10181
It looks like Xiotech only support fiber channel connection. as to how big the volumes should be and how many disks that really depends on your requirement. You might just create a set of LUNs and create ASM diskgroups on top of them.

How to choose a right server for Oracle Database!

Hi all,
Is there any formular that allows me to find the appropriate server configuration for Oracle database 11g?
Please help!
Thank you all.
Dan.
Edited by: Dan on 01:45 06-01-2013

Simply put ... no.
Determining the correct server is a dance between hardware vendors (one point of input to be treated with general distrust), internal expertise and experience working with similar systems, and most importantly understanding the behaviour of what you are building.
Here are some sample questions to start the ball rolling.
1. What operating system expertise does your organization have?
2. What operating system expertise is readily available in the community from which you hire applicants?
3. What type of application?
4. What are up-time expectations?
5. Requirements for high availability?
6. Requirements for time to perform a full recovery?
7. Requirements for security?
8. Storage footprint (dictates internal storage versus SAN, NAS, or ZFS)
9. Anticipated growth (3-7 years)
Everyone wants to sell you CPU clock-ticks, more RAM, more IOPS, etc. But the first thing you need to understand is the capabilities you require that are generic: Required of any solution. Only when you have a clear understanding of these factors are you ready to discuss whether the solution is a pizza box or an ODA ... an Exadata or an IBM System Z.
Far too often I find people purchasing RAM they don't need with CPU speeds that exceed the ability of their network infrastructure to move the data so pay special attention when you are ready to make your purchase to engineered systems like the ODA.

Compression for oracle database and index compression during import of data

Hi All,
I have a query , in order to import into oracle database and also have compression and index compression , do we have some kind of load args for r3load and also do we have to change the tpl file ?

Hello guy,
I did this kind of compression within migration project before.
I performed index compress first and then export -> import with table compress.
One thing you should take care, delete nocompress flag from TARGET.SQL (created by program SMIGR_CREATE_DDL, program SMIGR_CREATE_DDL created pure non-compression objects for these considered non-standard tables). For table columns > 255, we should not delete this flag.
Regarding to the index compress in source system, please check the following notes:
Note 1464156 - Support for index compression in BRSPACE 7.20
Note 1109743 - Use of Index Key Compression for Oracle Databases
Note 682926 - Composite SAP note: Problems with "create/rebuild index"

Is RAID 5 not recommended for Oracle database ?

- I am planning to install Oracle database
Here are the specs:
- Dell PowerEdge T610 server
- Windows 2008 R2 (64-bit )
- 24 GB memory
- Oracle 10g database (64-bit database)
- Our database is for an ERP based client server application
- Will have around 35-45 users
- Will have around 150-200 transaction per day ( 8AM-5PM) only database
- database would be around 10-15GB (data files)
Now I am planning to buy the hardware server, I heard that RAID 5 is not recommended for Oracle database.
Is it true ?
What do you recommended for Oracle database ? RAID 5 (or) RAID 1

johnpau2013 wrote:
I heard that RAID 5 is not recommended for Oracle database.
Is it true ?Kind off... as Oracle (as per the RAC Starter Kits for example) explicitly recommends SAME - as in Stripe And Mirror Everything.
This is a combination of RAID1 and RAID0.
However, you will also get whitepapers from storage vendors like EMC in partnership with Oracle, that explains how to configure and use RAID5 storage and how effective this is. And as some will tell you, RAID5 can work just fine with Oracle... and some others will grimace and tell you how bad an idea that is from personal experiences.
In a nutshell - RAID5 requires a parity calculation on each write. That is a very expensive overhead if that calculation impacts the fwrite() (file write) command of a process writing data to disk. It significantly slows down the write operation.
However, if that parity calculation is done asynchronously and does not effect the elapsed time for a fwrite(), then a fwrite() to RAID5 is as fast or as slow as it would be to RAID10 for example.
Unsure how many modern storage system supports off-loading the parity calculation and not impacting the write I/O call. This can be done using ASICs (Application Specific Integrated Circuits), specialised s/w on the storage server, etc.
Whatever you put in place - test the RAID config thoroughly up front and ensure that performance is up to specs. There's a utility called fio (Flexible I./O) written by a Linux kernel hacker that works for Oracle. It is an excellent utility to use to generate and test I/O - but it is Linux and Unix based.
Any specific reason using Windows? Linux is by far a more predominant 64bit operating system than Windows, and has significant higher market share in Oracle RDBMS than Windows. Given the fact that over 93% of the 500 fastest computer systems on this planet runs Linux, I'm always kind of amazed that some would still use Windows as a server-side o/s for Oracle.

RAID5 for oracle database

Hi,
Can you please confirm if RAID5 configuration is suitable for oracle database,?database size:50Gb OS:HP/UX version:10gr2
Sincerely
Shaimaa

user8913464 wrote:
what is the impact of this heavy disk write penalty, let's say that each disk size is 300Gb and number of disks is 4,database size:50GbThat depends entirely on the I/O system and I/O fabric layer.
Newer systems can receive the RAID 5 write into memory cache on the storage system (no parity block calculation overhead, no parity block write overhead). It then does this (the parity "stuff') when flushing that memory buffer to disk. Kind of like an Oracle delayed block cleanout where the changer of block data does not pay the penalty for cleaning and writing the block.
How well this actually works in practise, you need to ask your storage vendor. They should be able to provide white papers and test cases on the subject.
There's also issue with RAID5 ito data integrity and recovery and same may even suggest using an additional parity disk.
That said. Oracle recommends (as already commented) +SAME+ - Stripe And Mirror Everything. With is basically RAID10.
Keep in mind that storage architecture is changing fast - SSD and flash technology providing large storage caches. Even complete storage systems without a single disk platter of spinning rust. Then there's storage virtualisation, storage protocols and I/O fabric layers... It is not a simple topic as in the past and RAID is no longer as clean cut and straightforward as it used to be.

Steps if Oracle Database Crashed

Hi All,
Can someone write me sequence of steps if Oracle database get crashed. Just steps and not the detail.
Thanks
Praveen

First try 'recover database' command in sys login
If it fails,
1. See for the alert.log for exact error if any
2. if a control file is corrupted, create new control file
If there is hard-drive problem, bad sector etc then no chance ! Have to format or change hard drive and re-install oracle.

OIM 9.1.0 install connector for "Oracle Database 10g"

Hello,
Is anybody here who succeeded to install the connector for Oracle Database 10g into OIM 9.1.0?
If yes please give me a hint
Have a nice day!

Thanks guys for the quick responses.
But I have tried both the options for putting the jar in Third Party and also by uploading using the OOTB utility UploadJar.sh.
But it is giving the same error.
I have tired rebouncing the server and also Purge cached, but no success.
Just to mention again, I have tried with all the last 3 postgres JDBC4 driver available on the site (u mentioned).
So, any other clue?
Thanks in advance.

Current Patch Set for Oracle Database Release 11.2

Hi
I am upgrading oracle 10G to 11GR2 in AIX 5.3 Environment with SAP ECC6 , I have just just installled Oracle 11.2.0.1.0 according to the "Database Upgrade Guide -Upgrade to Oracle Database 11g Release 2 (11.2): UNIX". After database software installation , in upgrade manual in section 3.4.4 it says, you need to install current patch set for oracle database 11g R2 and referencing a SAP note 1431799.
I have just read note 1431799 which says Current Patch Set for Oracle Database Release 11.2 is not generally available for SAP customers until December 2010, also I donu2019t find the note 1522330 as mentioned in 1431799.
Please let me know how I can get current patch set to apply with Oracle 11.2.0.1.0 (Is it in SAP service market place?)
I also want to upgrade my installation to oracle 11.2.0.2, please let me know where I get the patch set to upgrade from 11.2.0.1.0 to 11.2.0.2,
or
I have to live with 11.2.0.1.0 and apply SAP Bundle Patch ( SBP)

Abu Al MAmun,
I understand from your posts that you recently upgraded to 11.2.0.2.
I am having the same difficulty, of finding the current patch set for 11.2. Could you please let me know how you worked around it?
Thanks,
Siri
Hello Everyone,
I did read the post on to how you have to install the current patch set for 11.2.
But honestly, it pretty much flew over my head.
I am trying to upgrade our SAP AIX 64 bit test system from Oracle 10.2.0.4 to 11.2.0.2.
And so far I have downloaded all the required sw for the upgrade, except for the current patch set 11.2.
This is what I have right now:
1) Oracle 11.2 AIX 64 bit upgrade sw - 51038805_part 1 to 51038805_part 7 and 51039800.
2) Database Patches -->Oracle 11.2.0.2 -->
All they have here is
a. Database RDMBS - SAP_112020_201012_AIX.zip and b. SAP_112020_201101_AIX.zip
b. OPatch - OPatch_11201_Generic_v3.zip and mopatch-2_1_6.zip
c. Database Vault - DV - >Generic - p9656644_112020_Generic.zip
If I am not wrong, the Database RDBMS files are nothing but the SAP Bundle Patches that have to be installed after installing the currrent patch set 11.2.0.2 using MOPatch.
But I did not find the currrent patch set 11.2.0.2.
Could someone please explain the process to me in detail? This being my first time , I am finding it a bit hard to catch up with some of the stuff.
Thank You!
Siri

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)?
The following is my configuration in the conf\mapViewerConfig.xml:
<map_data_source name="mvdemo12"
jdbc_host="127.0.0.1"
jdbc_sid="orcl12c1"
jdbc_port="1522"
jdbc_user="mvdemo"
jdbc_password="7OVl2rJ+hOYxG5T3vKJQb+hW4NPgy9EN"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
editable="true"/>

But it does not work.
After use "sqlplus mvdemo/[email protected]:1522/pdborcl", it connected to the Oracle database 12c.
Does anyone know it?
Thanks,

For 11.1.1.7.1 use the syntax for jdbc_sid, i.e.
//mypdb1.foo.com as described in the README,
- MapViewer native (non-container) data sources can now use database service name in place of SID. To supply a db service name, you will use the same jdbc_sid attribute, but specify the service name with double slashes in front, such as follows:
<map_data_source name="myds"
 jdbc_host="foo.com"
 jdbc_sid="//mypdb1.foo.com"
 jdbc_port="1522"
/>
For 11.1.1.7.0 use a container_ds instead.
i.e. instead of using
<map_data_source name="my_12c_test"
 jdbc_host="mydbinstance"
 jdbc_sid="pdborcl12c"
 jdbc_port="1522"
 jdbc_user="mytestuser"
 jdbc_password="m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q="
 jdbc_mode="thin"
 number_of_mappers="6"
 allow_jdbc_theme_based_foi="false"
 editable="false"
 />
use
<map_data_source name="my_12c_test"
 container_ds="jdbc/db12c"
 number_of_mappers="6"
 allow_jdbc_theme_based_foi="false"
 editable="false"
 />
In my case the Glassfish 3.1.2.2 JDBC connection pool definition was
Property
url jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name
Uncheck the Wrap JDBC Objects option in Advanced panel, i.e. the Edit JDBC Connection Pool Advanced properties page.
Add a JDBC resource for that newly created pool
Use that in mapviewerconfig.xml as above
