Enable hyperthreading for virtualized Oracle 11gR2 database (OEL57 64-bit)?
We are virtualizing our Oracle 11gR2 databases (running on OEL57 64-bit) on Vmware 5.1. I've read information at various locations that hyperthreading is not recommended for Oracle 11g database. One example is here, however, I seen many more:
http://bryangrenn.blogspot.com/2011/08/hyperthreading.html
My issue is that Vmware themselves recommends enabling hyperthreading for virtualized Oracle databases in their Oracle Databases on VMware Best Practices Guide.
Does anyone have any practical experience with this issue that can be shared? What are the advantages and disadvantages of enabling hyperthreading for our virtualized Oracle 11gR2 on OEL57 64-bit virtual machines
Thanks, Fred

If you read the comments on that blog you will see that the results are highly dependent on the type of CPU.
The effects can also be dependent on the nature of the workload: you may have CPUs that are fine with an OLTP workload, but don't scale as you might hope with a DW workload.

Opening OEM for two Oracle 11gR2 Databases in the same web browser automatically log out.
Hi to everyone,
I have an issue regarding Oracle Enterprise Manager in 11gR2. I have two database (SWPROD, PDPROD) in a single server. When I open the OEM URL for SWPROD it is successfully logged on but when I open the OEM URL for PDPROD and successfully logged on the other tab for SWPROD will automatically logged out. And when I switch to the other tab for PDPROD it is also automatically logged out. Both OEM URL is open in a single web browser like Mozilla Firefox. What would be the reason why both OEM URL will be logged out when I open them at the same time?
Thank you for your incoming response.Well it seems the only way to clear these out of EM was to shut BOTH RAC nodes down and power them up one at a time. Now the updates aren't shown as required and my compliance score is where it should be.
Is this a bug ? Seems pretty stupid to have to shut down both RAC nodes to fix this. Powering a single RAC node off and back on did not clear this.
Unless i'm missing something?? -
If we use result_cache_mode=force in oracle 11gr2 database then we don't need QSEl (third party software).
is the result cache feature is work same as qsel.
I am not able to find anything regarding it..please help...
http://www.qsel4oracle.com/FramePage_files/FramePageData.htmI don't know anything about QSEL, but can guess that it is some sort of caching solution sitting on Oracle.
Ideally, RESULT_CACHE_MODE should not be set to FORCE, as it will try to cache each and every SQL (and its results for different bind values).
But, if you have reasonably big SGA and within that SGA, if you have reasonably big result cache and you do RESULT_CACHE_MODE=FORCE, then you might not need third party caching solution.
Key question is, how big is reasonably big? that depends on size of data you are dealing with.
Good thing about result caching is, it works for user defined functions as well.
Also, you can enable result caching in certain sessions and disable it in certain session. -
Cannot connect to Oracle 11gR2 database from SQL Server 2005
Both SQL Server (Windows) and Oracle (Linux) are in 64bit environments.
I have done the following on a Windows 2008 R2 with SQL Server 2005:
Install InstantClient from Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) to C:\Oracle
Install oledb from 64-bit ODAC 11.2 Release 3 (11.2.0.2.1) for Windows x64 by executing install.bat oledb c:\oracle odac
Note: Not sure whether 11.2.0.2.1 version of ODAC will cause any problem since I cannot find 11.2.0.1.0 version.
I have checked the Allow inprocess of OraOLEDB.Oracle provider in SSMS.
I have executed sp_addlinkedserver @server = 'ORACLE_TEST', @srvproduct = 'Oracle', @provider = 'OraOLEDB.Oracle', @datasrc = '##.##.##.##:1521/TEST'
The ##.##.##.## is the ip address of the Linux server which has the Oracle 11gR2 database TEST.
I have executed sp_addlinkedsrvlogin @rmtsrvname = 'ORACLE_TEST', @useself = 'FALSE', @rmtuser = 'xxxx', @rmtpassword = 'yyyy'
The xxxx is the oracle username and yyyy is the password for the oracle user xxxx.
I know the oracle database TEST is up since I have setup connection in Oracle SQL Developer having:
##.##.##.## as the hostname
1521 as the Port
xxxx as the username
yyyy as the password
TEST as the service name
When I click Test Connection for the linked server ORACLE_TEST in SSMS, it just hang.
When I issue a query like select count(*) from oracle_test..xxxx.table1, it just run forever. I'm not so sure how to query an oracle table. I have also tried select count(*) from oracle_test.xxxx.xxxx.table1.
When I retype the password in the Linked Server Properties, it just run forever.
Do I need to create a tnsnames.ora on the Windows machine?
Do I need to change the tnsnames.ora on Linux machine?
I'm very new to Oracle.This forum is dealing with connections from an Oracle database to SQL Server - so the Oracle database is the driving site and this is the way round from your linked server set up.
As you're suing the instant client you might post your issue in the instant client forum:

Oracle 11gr2 database installation using ASM on standalone Server.
Hello Guys,
Environment is as below:
Oracle 11gr2
ASM
Enterprise Linux Server release 5.5 (Carthage)
I never did oracle 11gr2 installation using ASM and I need to install Oracle software on standalone server and then create database 11g Release 2.
I have following doubts:
1. Do we need to install Grid infrastructure software for standalone server as well ?
2. Does Grid Infrastructure software comes separately or alongwith DB software ?
3.Is Grid software same for RAC and standalone server setup ?
4.Do we need to create user Grid for installation of Grid for standalone server as well ?
can anyone give me full steps from scratch ?

JDBC API ( JSR 169 ) Implementation for accessing oracle lite database
We are developing an application using IBM J9 (CDC and Foundation Profile) on Pocket PC 2003 environment with SWT as the front end development. We are using Oracle Lite 9i as the Client database.
We have sucessfully installed Oracle Lite and was able to create tables in the database.. however we could not find the JDBC API (java.sql and javax.sql packages which is JSR 169 JDBC 2.0/3.0) inorder to load the JDBC driver(OLITE40.jar) and access the oracle Lite Database on Pocket PC.
IBM J9 Micro Environement does not have this support.
I am wondering if Oracle provides this implementation.
If not is there a get around.
the client database is crucial to the application and i would really appreciate an answer to our problem.Check out

Network speed for spatial oracle-Arcsde databases
Hi all
I am working in a oracle -ArcSDE production database environment. The data size is huge and more than 100 users are connected to the database. Wht should be the Reccomended Network speed for the database?
Thanks in Advance
AlbinAlbin,
Obviously the faster the network, the quicker you will move data from the database to the client. However, in most cases (at least with a 1Gb network) I find that the neither the database or the network are usually the bottleneck with ArcMap, but instead the client-side "SDE"/rendering process. This is especially true when returning large numbers of geometries. The 10.x engine just chokes on anything more than a few thousand objects, and unfortunately the render model they use causes a full refresh on any movement / zoom, repeating the painful process over and over.
In a nutshell, it is simply a poorly designed architecture for today's loads. Our custom Java WebStart GIS client runs circles around it. Hopefully the new project they are working on will improve performance, especially when using native SDO_GEOMETRY data - but I haven't really had time to pound on it yet to verify that one way or another.

Moving a 32 bit Oracle 9i database to 64 bit on a different server
Hello,
We have a 24 GB database with Oracle 9.2.0.7 (32 bit). As the hardware of this server is getting obsolete, it is planned to move this instance to another server, which has 64 bit Oracle software of same version (9.2.0.7). In this scenario what is the best way to move the instance?
Is it only the full export from 32 bit server and import into 64 bit server(after creating the instance there)?
Since this is a 24 GB database, and target server is 8 gb of ram, any pointers on how long the import process can take?
There is a documentation to change word size, I can run utlirp.sql as suggested here:
http://www.orafaq.com/forum/?t=rview&goto=258668#msg_258668
But I have some doubts as I mentioned in that post. Can you please share your suggestions?
Thanks,
NiravHi
Is there some document or steps to follow when creating the instance on the new server The database move is easy, and here is one way to move the schema, fast:
http://www.dba-oracle.com/oracle_tips_db_copy.htm
And then, you just run the script to change the wordsize for 64-bit:
Also, after your migration, watch out for common performance issues:
http://www.dba-oracle.com/t_bad_poor_performance_upgrade_migration_32_64_bit.htm
Also, note that Oracle has changed the optimizer costing model from "IO" to CPU" in 10g, and shops that combine an upgrade to 64-bit servers with a 10g migration may want to look at changing the new default for _optimizer_cost_model.
Going 64-bit means that you can now allocate very large RAM data buffers and increase your shared_pool_size above two gigabytes. However, it is important to remember that there are downsides to having a super-large db_cache_size. While direct access to data is done with hashing, there are times when the database must examine all of the blocks in the RAM cache. These types of database may not always benefit from an upgrade to a 64 bit server:
Systems with high Invalidations: Whenever a program issues a truncated table, uses temporary tables, or runs a large data purge, Oracle must sweep all of the blocks in the db_cache_size to remove dirty blocks. This can cause excessive overhead for system with a db_cache_size greater than 10 gigabytes.
High Update Systems: The database writer (DBWR) process must sweep all of the blocks in db_cache_size when performing an asynchronous write. Having a huge db_cache_size can cause excessive work for the database writer. Some shops dedicate a separate, smaller data buffer (of a different blocksize) for high-update objects.
RAC systems: Oracle RAC and Grid does not perform optimally with super-large data buffer RAM, as available in 64-bit systems. You may experience high cross-instance calls when using a large db_cache_size in multiple RAC instances. This inter-instance "pinging" can cause excessive overhead, and that is why RAC DBA's try to segregate RAC instances to access specific areas of the database. This is why Oracle 10g grid server blades generally contain only 4-gig RAM.
Hope this helps. . .

Steps to follow for Installing Oracle SOA 11g in 64 bit Windows 7 machine
Hi,
I have successfully installed Oracle SOA 11g components in Windows 32 bit machine by following the downloading the installers for Windows 32 bit and following the steps mentioned in the Quick Start Guide for SOA Suite and BPM Suite.
Now I am trying to install Oracle SOA components in Windows 7 64 bit machine.Are the installation steps I followed for 32 bit is applicable for 64 bit too?Or are there any difference?
In the download section of installers,I could see one for 32 bit, linux and generic.Can you guide me which one I need to download for 64 bit machine?
Thanks in advance.I followed for 32 bit is applicable for 64 bit too?Or are there any difference?Steps followed for 32 bit installation would be same as for 64 bit. The only difference would be 64 bit JDK as it's required for win 7 to run the installation binaries of SOA Suite.
http://www.oracle.com/technetwork/java/javase/downloads/java-se-jdk-7-download-432154.html
I could see one for 32 bit, linux and generic.Can you guide me which one I need to download for 64 bit machine? You can use even 32 bit installer for 64 bit machine ( it works like charm for DEV like environment)...
but as per Oracle doc they prefer to use generic installer.

I was wondering if this might have anything to do with the i386 software prerequisites. Speaking of Oracle 11gR2 x86_64, the need for i386 libraries was removed with 11gR2 11.2.0.2. Or in other words, one can go straight to 11.2.0.2 without the need to install any 32-bit libraries.
Under Oracle Linux 5 x86_64, the "oracle-validated" package triggers the installation of several i386 packages. Under Oracle Linux 6 x86_64, the oracle-rdbms-server-11gr2-preinstall package uses x86_64 only. Under Oracle Linux 6, i386 changed to i686.
For what it's worth, I have installed Oracle 11gR2 database 11.2.0.1 under Oracle Linux 6.1 to 6.3, both x86_64, simply by using the oracle-rdbms-server-11gr2-preinstall package, and so far have not noticed any problems. Is there some information available, why 11.2.0.1 (x86_64) should not be used or is not certified for Oracle Linux 6 (x86_64)?
Thanks.I was afraid of that. Since the question is Oracle Linux 6 specific, I thought I'd try my luck here, thinking that if I get an answer, then probably here. Maybe it was not very realistic to get an answer anyway.
For what it's worth. Using "oracle-validated" under Oracle Linux 5, and "oracle-rdbms-server-11gR2-preinstall" under Oracle Linux 6, I was able to install Oracle 11gR2 11.2.0.1 just fine, both platforms x86_64 and 32-bit. I have not found any operational issues yet and it seems to run perfectly well.
The only trouble I had was with Grid Infrastructure 11.2.0.1, and here 11.2.0.3 is indeed required for it to install. I made a custom patch, just a few lines and after that 11.2.0.1, both x86_64 and 32-bit installed just fine and is fully operational.
I'm though I could post the patch. I guess it might make those people happy who do not have access to Oracle support and download 11.2.0.3. The patch will allow them to use the 11gR2 OTN version and install it under Oracle Linux 6. It won't be certified, but it is good enough for the purpose of education.
I'm closing the thread. -
Ntp Server for Oracle 11gr2 (oracle clusterware) on HP-UX
we are planning to configure a ntp server on Windows 2003 server for our Oracle 11gr2 RAC (2 nodes) on HP-UX but we have some issues to be clear. Following are the details for our environment.
RAC : Oracle Clusterware (2 nodes)
Database : 11gr2
OS: HP-UX B11
Hardware: HP Intergrity Blade Servers BL860c i2
ntp server : HP Proliant
if our ntp server fails how the both nodes will manage the time?if our ntp server fails how the both nodes will manage the time?Use NTP insure that all cluster nodes must be synchronized to the same time ,in 9i , 10g and 11gR2 Oracle Clusterware includes the Cluster Time Synchronization Service (CTSS) . On startup Clusterware checks for a NTP configuration, if found, CTSS goes into Observer mode. This means it will monitor the clock synchronization and report in the Oracle Clusterware alert log if it finds a problem. If it does not find a NTP configuration, CTSS will be active .
