Note 830576 - Parameter recommendations for Oracle 10g

hi all DBA experts.
I am not good familiar with Oracle database while i read a Note 830576 - Parameter recommendations for Oracle 10g. in which SAP General Recommendation:
You should delete obsolete initialization parameters from the profile.
To determine which obsolete parameters are currently set, proceed as follows:
SQL> SELECT NAME FROM V$OBSOLETE_PARAMETER WHERE ISSPECIFIED = 'TRUE';
when i execute above command then result is no rows selected
while there are many parameters in above SAP Note which are already obsolete and not set in initSID.ora file.
for exp. the parameter OPTIMIZER_INDEX_COST_ADJ is showing
#### OPTIMIZER MODE
#optimizer_index_cost_adj = 10
as you know that this parameter is very important regarding System Performance.
now please guide me . I have to set these parameter or no need while there is not showing any parameters against obsolete command.
waiting you valuable reply.
Regards,

hi both,
thanks for knowledge sharing with me other SDN users,
Dear Orkun,
Ok. At this stage, I can recommend you that apply what they have suggested,
in the message. So, you already did a part of it by configuring
Oracle parameters, already.

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:

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 (<i>Flexible I./O</i>) 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.

Error while creating datasource userdsn for oracle 10g Errorcode (998)

while creating datasource userdsn for oracle 10g i am getting error "The setup routines for the oracle in OraDb10g_home1 odbc driver could not be loaded due to system error code 998" please give reply soon

Thanks for your reply , Steve.
I noticed that there is a default datasouce on the EM with the following parameters:
<data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="OracleDS"
          location="jdbc/OracleCoreDS"

          ejb-location="jdbc/OracleDS"

          username="scott"
          password="->pwForScott"
          url="jdbc:oracle:thin:@localhost:1521:oracle"
          inactivity-timeout="30"
     />
The location and xa-location attributes that I use for my "test" data source are the same as the default one. So, could this be the issue?
What should be the values for location and xa-location attributes from my "test" data source?
Any help will be greatly appreciated.
Thanks,

Oracle gateway for Oracle 10g DB on Windows 64 bit server

Is there any place that I can find Oracle dateway for Oracle 10g DB on Windows 64 bit server? I can only find Gateway for Oracle 11g on Windows 32 bit server. Please help me to identify this. Thanks.

yingkuan:
Thanks a lot. The link tells the details. It seems that Oracle has not release Gateway for Oracle database 10.2.0.x on Windows 64 bit server. Probably they don't do it.
So under this circumstance, if I want to install Gateway (32 bit) on Oracle 10.2.0.3 DB on Windows 64 bit server for Teradata, I probably have to install Gateway software in another Oracle Home, then configure it right. Please give more advice on this. 32 bit Gateway will work for 64 bit database?

Can't Create the ODBC connection for Oracle 10g

Hi,
I am working with Oracle 10g Database Release 2 in windows XP professional. I am trying to create an ODBC connection for oracle but become failure because its generating the following errors:
system error code 998
could not locate the setup or translator library
Please help me how can I solve this problem and create the ODBC connection for oracle 10g database.
Best Regards,

could not locate the setup or translator libraryThe symptom described is typical of an incorrect system env PATH setting (used by the data source admin tool), compared to that of the Oracle Home (specifically, path $OH/bin). The odbc driver config routine will search directories listed in PATH variable for necessary libraries (Client dll's). If some library fails to load (from e.g. oraoci*.dll or oraclient10.dll) it will probably error out, as in your case.
Are you creating the odbc dsn on the databse server host or on some other machine? I.e. are you using the db host as a client or not?

How to change timeout parameter value in Oracle 10g R2

Anyone knows how to change timeout parameter value in Oracle 10g Database R2?

A search of MetaLink for that error turns up a number of hits, most of which a very situational specific. Exactly what are you doing when you get this error? Are you connecting over an ODBC connection? Are you getting it on a connection request? At db shutdown? During a long-running query?

Errors using DBMS_SQLTUNE Advisors for Oracle 10g

I get errors trying to tune the below query for Oracle 10g using the DBMS_SQLTUNE advisors.
It happens when I wrap either a large block of PL/SQL code that uses bind variables or multiple nested subqueries with multiple JOIN conditions in a SELECT query statement that I wish to tune using the 10g SQLTUNE advisors.

Hi, I was trying to use the DBMS_SQLTUNE package to tune my sql statements used in the huge procedure. I can successfully create a task and execute it. But when I run report tuning task, I'm always getting error like the one in below example. Two questions I have now.

Enable autoarchiving for Oracle 10g RAC db

Hello
What are the steps to enable autoarchiving for Oracle 10g cluster database?
It is currentrly in noarchivelog mode.
Thank you,
Yelena

Hi.
I think that this has been improved in 10g, so that we can do an exclusive mount on any database in a RAC without setting cluster_database to false. Also the parameter log_archive_start has been depreciated so the steps is simply (assuming that you by default wants to use db_recovery_file_dest to store archived redo logs)
1) Shutdown immediate (instance 1)
2) Startup mount
3) Alter database archivelog
4) Alter database open
Repeat this sequence for all nodes in the RAC.
And the best is to leave the log_archive_format by it's default value, to ensure that the incarnation of the database is represented in the archive log name.
(On 10g, backupsets and archivelogs are usable beyond different reincarnation of a database, so there is a good change that S% or s% will repeat itself after an open resetlogs).
Hopes this might help you.
Good Luck

VSS Agent for Oracle 10g ?

Hi there,
I have SAP NW2004s, Windows 2003 server 64bit, Oracle 10g
4 partition with 1 hdd, C for OS, D for SAP application E for system and oracle logs+archived, F for only database files
We are trying to get backup in extrinal HDD 3TB HDD... through Symantic exec backup utility ver. 12
C and D drivers are backup fine, but sometime when server very busy and symantic start full backup for E and D drive database shutdown... sap instance is fine, but only DB instance is stoped
We are not using Symantec Agent software, is there any other software can help for that for-exmaple VSS for oracle 10g... if yes, where may i get this software any link?
Why we are not using BR tools:
1 - as i maintion before when I select "E" drive which is all logs files located symantec stoped db instance
2 - in case if i am taking backup from brtools full backup online + archived so its only take database backup + archived, not all others structure in case hard-drive failer, and data restore from symantec so its will be ok with C drive and D drive, but its nohting resotre for E and D
when I try to restore from oracle brtools to restore its getting an error for missing structure in E
so thats why I am looking only one solution either perfect symantec with online backup
please give me some advised
Thanks

Hi,
Please use the standard & reliable Backup/Restore methods for any DB, to avoid more headache while Backup/Restore Operations.
Please refer [this thread|Re: Need some advise]. it will attend your most of questions. Some other alternatives (without using Backup agent) are mentioned there.
If you use Backup Agent to perform any DB backup, then It will be reliable method to perform Backup/Restore operations of DB.
With BR*tools u can also perform Non-Database Backup. Please refer [this link|http://help.sap.com/saphelp_NW04/helpdata/en/0c/cd271365debc42bef96ac7fd907787/frameset.htm] and other relative links.
If you have configured the Backup Exec utility with Oracle agent on the DB server, then you can perform Online Backup by deselecting "Perform the backup offline" option withing that Oracle Backup Job properties.

Bhavik G. Shroff
