Best practice for install oracle 11g r2 on Windows Server 2008 r2

Dear all,
May I know what is the best practice for install oracle 11g r2 on windows server 2008 r2. Should I create a special account for windows for the oracle database installation? What permission should I grant to the folders where Oracle installed and the database related files located (datafiles, controlfiles, etc.)
Just grant Full for Administrators and System and remove permissions for all others accounts?
Also how should I configure windows firewall to allow client connect to the database.
Thanks for your help.

Best practices for gathering statistics in 10g

I would like to get some opinions on what is considered best practice for gathering statistics in 10g. I know that 10g has auto statistics gathering, but that doesn't seem to be very effective as I see some table stats are way out of date.
I have recommended that we have at least a weekly job that generates stats for our schema using DBMS_STATS (DBMS_STATS.gather_schema_stats). Is this the right approach to generate object stats for a schema and keep it up to date? Are index stats included in that using CASCADE?
Is it also necessary to gather system stats? I welcome any thoughts anyone might have. Thanks.

Hi,
Is this the right approach to generate object stats for a schema and keep it up to date? The choices of executions plans made by the CBO are only as good as the statistics available to it. The old-fashioned analyze table and dbms_utility methods for generating CBO statistics are obsolete and somewhat dangerous to SQL performance. As we may know, the CBO uses object statistics to choose the best execution plan for all SQL statements.
I spoke with Andrew Holsworth of Oracle Corp SQL Tuning group, and he says that Oracle recommends taking a single, deep sample and keep it, only re-analyzing when there is a chance that would make a difference in execution plans (not the default 20% re-analyze threshold).
I have my detailed notes here:
http://www.dba-oracle.com/art_otn_cbo.htm
As to system stats, oh yes!
By measuring the relative costs of sequential vs. scattered I/O, the CBO can make better decisons. Here are the data items collected by dbms_stats.gather_system_stats:
No Workload (NW) stats:
CPUSPEEDNW - CPU speed
IOSEEKTIM - The I/O seek time in milliseconds
IOTFRSPEED - I/O transfer speed in milliseconds
I have my notes here:

Hope this helps. . . .

What is best practice for installing Yosemite

I am currently on OS X Mavericks version 10.9.5 Macbook pro 13. 2.6 ghz intel for i5, 8gb 1600 mhz ddr3.
I am now downloading yosemite 10.10.1 but since i've been reading all these negative feedback so far, i am having second thoughts if i should continue to install the upgrade or not.
Any suggestion What is best practice for installing Yosemite? Or is it not yet time to upgrade since the platform is premature yet?
Thanks in advance.

Check your apps are compatible with 10.10 - roaringapps.com
http://www.etresoft.com/etrecheck can show what is running & installed - look for updates on the developer own sites.
If you have many kernel extensions or startup items look for updates to them too
Take a full bootable backup to another disk via Carbon Copy Cloner, Super Duper! or Disk Utility
Disconnect the backup before you begin any install (ideally set it aside & leave it untouched incase you need to go back to 10.9)
Personally I prefer a clean install when there are signs of multiple migrations (if you have upgraded several OS for a period of years). Setup Assistant/ Migration Assistant can import user data from a backup, but consider that Apps & 'other data' should be manually reinstalled from the latest versions.
If you clean install (erase the HD before installation) then make sure you deauthorise iTunes & any other apps that are associated online (like find my Mac).

What are the best practices for Database management and performance tuning?

Hello,
I want to ensure that I am using the best practices for managing and maintaining our Database.
Is there any documentation out there that outlines how to maintain and ensure top performance out of our database?
Thank you!
John Sefton

I appreciate the responses, however this is not the information I am looking for.
I am specificaly looking for best practices invloving the managment and performance tuning.
Example: are their tools that I can install that will monitor the size and response time of the database and alert me if there is degradation in performance?
Are there specific periodic activities I should be doing to garuntee that my database will continue to function that way it is supposed to?
Or is this a fire and forget solution that does not need this attention?

JSF - Best Practice For Using Managed Bean

I want to discuss what is the best practice for managed bean usage, especially using session scope or request scope to build database driven pages
---- Session Bean ----
- In the book Core Java Server Faces, the author mentioned that most of the cases session bean should be used, unless the processing is passed on to other handler. Since JSF can store the state on client side, i think storing everything in session is not a big memory concern. (can some expert confirm this is true?) Session objects are easy to manage and states can be shared across the pages. It can make programming easy.
In the case of a page binded to a resultset, the bean usually helds a java.util.List object for the result, which is intialized in the constructor by query the database first. However, this approach has a problem: when user navigates to other page and comes back, the data is not refreshed. You can of course solve the problem by issuing query everytime in your getXXX method. But you need to be very careful that you don't bind this XXX property too many times. In the case of querying in getXXX, setXXX is also tricky as you don't have a member to set. You usually don't want to persist the resultset changes in the setXXX as the changes may not be final, in stead, you want to handle in the actionlistener (like a save(actionevent)).
I would glad to see your thought on this.
--- Request Bean ---
request bean is initialized everytime a reuqest is made. It sometimes drove me nuts because JSF seems not to be every consistent in updating model values. Suppose you have a page showing parent-children a list of records from database, and you also allow user to change directly on the children. if I hbind the parent to a bean called #{Parent} and you bind the children to ADF table (value="#{Parent.children}" var="rowValue". If I set Parent as a request scope, the setChildren method is never called when I submit the form. Not sure if this is just for ADF or it is JSF problem. But if you change the bean to session scope, everything works fine.
I believe JSF doesn't update the bindings for all component attributes. It only update the input component value binding. Some one please verify this is true.
In many cases, i found request bean is very hard to work with if there are lots of updates. (I have lots of trouble with update the binding value for rendered attributes).
However, request bean is working fine for read only pages and simple binded forms. It definitely frees up memory quicker than session bean.
----- any comments or opinions are welcome!!! ------

I think it should be either Option 2 or Option 3.
Option 2 would be necessary if the bean data depends on some request parameters.
(Example: Getting customer bean for a particular customer id)
Otherwise Option 3 seems the reasonable approach.
But, I am also pondering on this issue. The above are just my initial thoughts.

Any best practice for Key Management with Oracle Obfuscation?

Hi,
I was wondering if anyone is aware if there are any best practices regarding key management when using Oracle's DBMS_OBFUSCATION_TOOLKIT? I'm particularly interested in how we can protect the encryption/decryption key that we would use.
Thanks,
Jim

Best practice for installing many SL-500

Hi,
I have just bought 25 SL-500 and are to buy a hundred more in half a year.
They are all model 2746-4DG
I wish to make a special installation with all standard software of my office and transfer this to a DVD as a Ghost Image.
Normally (in my old job) I would do this by installing everything I need on one PC, and do a sysprep for making a factory image. After this I would make a Ghost image of the disk and transfer this to a DVD.
But in my old job we did not buy OEM windows XP - we had a VOL agreement.
I would really like to install all PC's with only one Windows Key and skip activation, but can this be done if I buy one VOL license and media for Windows XP and use this key on all PC's.
And is it legal for me to do so?
Kind regards

Best practices for installing Win 10 under Hyper-V on Server 2012R2 host

Yeah, yeah, I know I could probably get my answers after spending 10 hours reading hundreds of isolated threads here. I've already put in about 2 hours, and I'm exhausted. Plus, this site does not have a very sophisticated search function.
I want to install Win10 as a VM on my Server 2012R2 machine. I am not currently hosting any other VMs, so my first decision was whether to try it using Hyper-V or VirtualBox. I started with VirtualBox, but I ran into two problems: networking
and video. Also, VirtualBox itself seems to have some issues with failing to install the extension pack. So now I think I'll give Hyper-V a shot.
I found some blog posts from last year providing guidance on setting up Hyper-V for Win10, but given the rate of change of this beta OS, I expect there are many new "features" that can be mitigated against by specific settings on the VM.
Some specific questions:
1. Generation 1 or Generation 2 in the Hyper-V setup? The blogs I've seen say to use Gen1, but provide no justification. Perhaps because they are using Win8 as the host? I am using 2012R2.
2. Does the Win10 ISO file need to be continually available to the VM, or is it only used in the initial installation?
3. How do I get the VM to access the GPU card, which has lots of memory, over the useless onboard video chip which only has 8MB and no 3D instruction set? This was a dealbreaker with VirtualBox.
4. I anticipate many issues with networking, but I'll start with this: I have dual onboard NICs going into a managed switch. Should I just give one physical NIC to the VM and let the host have the other? I think I'm going to have some issues
with DHCP IP address assignment, but we'll see. Any best practices here would be helpful.
Thanks.

>1.
I'd use Gen 1, that is a BIOS type boot, but that's just because I've had
less trouble than with Gen2 VM's.
>2.
Only during install, refresh, reset, or sfc.
>3.
No virtualization solution does it easily, but there is RemoteFX if you can
get a Windows 10 client to use it. I've never tried.
http://social.technet.microsoft.com/wiki/contents/articles/16652.remotefx-vgpu-setup-and-configuration-guide-for-windows-server-2012.aspx
>4.
That's what I would do (assigning one NIC to the VM, and one the host). If
both are receiving an IP address right now from DHCP, they will continue to
do so the new way unless you have a managed switch that would prevent more
IP addresses. It's hard to tell...
