Suitable Processor for Oracle 10g

Hi All ,
Currently, Our Oracle 10g with RAC (Real Application Cluster) is running in the Server Sun Fire V240 (SUNW,UltraSPARC-IIIi) with 4GB of RAM.
We have an idea to upgrade the processor. Please give me your suggestion, which processor is best for Oracle 10G with RAC.
I am awaiting for your response.
Regards,
R. Rajesh Kannan.

It would depend on the load. How many people using it, and what are they all doing.

Chosing processors for Oracle database 10g 64 bits

Hi,
I have a customer that is planning to buy Oracle 10g 64 bits on a server Windows 2003.
My customer is interested in a processor that handles a lot of data in and out in a very effective way and the processor should be able to perform a great number of calculations in the database.
Are there some processors that are better than others for Oracle 10g 64 bits?
For example: Is Itanium better than Xenon? Or is Xenon better that AMD?
Any suggestions will be appreciated.
Thanks in advance.

It's a very long article!
I'm not sure of its relevance, I'm afraid... not enough time to read it!
Kevin Closson's blog has a lot of good stuff about NUMA. Software can be optimised to run on NUMA processors. Oracle is. The parameter means you switch off those optimisations. It means Oracle works fine, but less well than it is theoretically capable of, because you are making it believe it's running on a non-NUMA processor.
From memory, the specific NUMA optimisation that caused the issue is that the buffer cache is divided up internally so that each processor can handle different bits of it, distributing cache management chores amongst all the available cores. Excellent in theory. Unfortunately, the bug meant that a query that runs on one processor core got its data cached in that processor's "bit" of the buffer cache... and if you re-ran the query and happened to end up on a different core, the new core behaved as though no data had been cached, and fetched it all again from hard disk. Performance WITH the NUMA "optimisation" was accordingly abysmal because you effectively had little or no buffer cache. The workaround is to disable the NUMA optimisation and pretend you've only got one core: Oracle then has a monolithic buffer cache -which introduces performance issues of its own, of course, but at least your data gets cached properly!
The bug is allegedly fixed in 10.2.0.3, but we spent over a 16 months getting it sorted, and by that time, we'd given up and gotten the Intel boxes, so I've no idea whether it was really fixed or not... and, of course, you might not be able to patch to that level anyway for internal politics or other reasons.

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"
          xa-location="jdbc/xa/OracleXADS"
          ejb-location="jdbc/OracleDS"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          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,
Shyam

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?

Long-term retention backup strategy for Oracle 10g

Hello,
I need design a Archivelog, Level 0 and Level 1 long-term retention backup strategy for Oracle 10g, It must be based in Rman with tapes.
¿Somebody could tell me what it's the best option to configure long-term retention backups in Oracle?, "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1825 DAYS;" It's posibble ?
Regards and thanks in advance

Hello;
RECOVERY WINDOW is an integer so yes its possible. Does it make sense?
Later My bad, this is Oracle 11 only ( the gavinsoorma link ) . Getting harder and harder to think about 10. Don't think I would use RECOVERY WINDOW.
I would let the tape backup system handle the retention of your rman backups.
Using crosscheck and delete expired commands you can keep the catalog current with the available backups on tape.
Oracle 10
Keeping a Long-Term Backup: Example
http://docs.oracle.com/cd/B19306_01/backup.102/b14191/rcmbackp.htm#i1006840
http://web.njit.edu/info/oracle/DOC/backup.102/b14191/advmaint005.htm
Oracle 11
If you want to keep 5 years worth of backups I might just use KEEP specific date using the UNTIL TIME clause :
keep until time 'sysdate+1825'More info :
RMAN KEEP FOREVER, KEEP UNTIL TIME and FORCE commands
http://gavinsoorma.com/2010/04/rman-keep-forever-keep-until-time-and-force-commands/

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.

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,

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.

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?

Where can I download the ODBC driver for Oracle 10g XE?

Should I go for Oracle 10g OCA/OCP or 11g OCA/OCP Certification?

Hi all,
I am lil bit confuse to decide about my oracle core dba certification.
Please help me to know, as per the present requirements of the business organizations.
***Should I go for Oracle 10g OCA/OCP or 11g OCA/OCP Certification?***
Hope u guys answer me earliest.
Thanks & Regards,

Most likely, it doesn't matter too much. I doubt that most employers are terribly concerned with what recent version of Oracle you have a certification on.
That said, if it matters
- What does your organization use? What are their plans to upgrade? If your company still uses 9.2 primarily and has plans to upgrade to 10.2 this year, you're probably better off with a 10g certification. If your company is already running mostly 11.2, you're probably better off with an 11g certification.
- What do most employers in your particular part of the world tend to use? What do job postings in your particular part of the world generally list?

SUNWsprox package with solaris 10 for Oracle 10g Installation....

Hi
I am in problem with a Solaris 10 package "SUNWsprox - Sun workshop Bundled 64-bit make library" for Oracle 10g Installation. I checked the CDs (In the /.../products) but did't found this packege. Can any one tell me please can I go without this package or where I found this package...Please Its very URGENT for me....
Thanks
Mohammed Tanvir

Hi...
I had the same issue, but found out that the SUNWsprox was replaced by SUNWsprot. The OUI 10.1 Release 2 will 'pass' as the doco in the Oracle quick install guide is wrong (as well as 10g Application Server).
The only way to lay a 10g Release database on Solaris 10 is to lay the software doen only, then cd in the .../bin directory, step your Rdbms ORACLE_HOME, ORACLE_SID, LD_LIBRARY_PATH and of course the DISPLAY (is X-windowing into the server), and run dbca manually. Oracle 10g is a bit buggy.

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.

2) Can I able to use to this package to tune a procedures instead of sql statement?
