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.

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.

Server Sizing For Oracle Database
Hi All,
I need a server sizing for the below mentioned architecture:
This application is basically for logistics company which we are planing to host it centrally with two server's one server for application and one for oracle database along with DR site (Other Location). There are four locations and each location will have 20 users who are going to access this application (20 x 4= 80 Users). We are using MPLS network of 35 mbps bandwidth.
1. Application server: Windows server 2008 R2
2. Database Server: Windows server 2008 R2, Oracle 11g r2
I need a server sizing documents.
Thanks........EdStevens wrote:

Thanks........I'd seriously reconsider hosting Oracle db on Windows. Obviously there are many, many shops that do. And obviously it is often a case of the fact that they do not have (and choose to not acquire) expertise in Linux. But I've been in IT for 30+ years and have worked on IBM S-370 and its variants and descendents, Windows since v3, DEC VMS, IBM OS/2, Solaris, AIX, HPUX, and Oracle Linux. The first Oracle database I ever created was on Windows 3.11 and at that point I had never seen *nix. Now I am in a position to state that Windows is the worst excuse of an operating system of any I have ever used. I am constantly amazed/amused by how often (at least once a month on schedule, plus unplanned times) that our Windows SA has to send out a notice that he is re-booting his servers. I can't remember the last time we had to reboot a Linux server ( I have 4 of them)
Yes, I'm biased away from Windows, but that bias comes from experience. Hardly a day goes by that I don't see something that causes me to say to whoever is in earshot "have I told you how much I hate Windows?"I was going to refrain from commenting on that, as I assumed they're a Windows shop and aren't open to any other OS (but my assumption could be incorrect).
I haven't been working in IT for as long as many of the folks around here, only about 10 years. I'm a former system admin that maintained both Linux and Windows servers, but my focus was on Windows. In the right hands, Windows can be rock solid. If a system admin has to reboot Windows servers often, he is most likely doing something wrong, or is rebooting for security updates. It's never as simple as "Windows Sucks," or "Linux Sucks;" it all depends on who's running the system (again, in my opinion).
I have seen some windows servers run uninterrupted for so long no one could remember the admin password. But more often memory leaks and the "weekly update" (replacing last weeks bugs with this weeks) is the culprit.
Yes, it really is sad how often you have to reboot for updates if you want to keep your system current. Mind you, it's better to have the fixes then to not have them (maybe). I rebooted my servers about once every month at my old place... which is not that bad.
With that said, in my experience, Oracle on Windows is a major pain. It takes me much longer to do anything. Once you get proficient with a CLI like the bash shell, the Windows GUI can't compare.Agreed. One of my many complaints about Windows is the poor excuse of a shell processor. I'm pretty proficient in command line scripting, but still cringe when I have to do it. Practically every line of code I write for a command script is accompanied by the remark "this is so lame compared to what I could do with a shell script". Same for vi vs. notepad. But my real problem is the memory leaks and the registry. I'm fairly comfortable hacking certain areas of the registry, but the need to and the arcane linkages between different areas of the registry and how they influence 'process environment' remains a mystery to all but a tiny minority of admins. Compare to *nix where everything is well documented and "knowable".
One (of many) anecdotal experiences, this with my personal Win7 laptop. One time it crashed and refused to reboot. A bit of a google search turned up some arcane keystroke sequence to put it into some sort of recovery mode on bootup .. similar to getting into the bios, but the keystroke sequence was much more complex .. it may have involved standing on one foot while entering the sequence. Anyway, it entered a recovery process I've never seen before or since and repaired everything. My first thought was "hey, that was pretty cool." Then my second thought was 'but only Windows would need such a facility.
Bottom line? To paraphrase a famous Tom Hanks character, "My momma always said Windows was like a box of chocolates. You never know just what you'll get."Haha... I like that one. Yes, the registry is definitely horrible. It's amazing to me that a single point of failure was Microsoft's answer to INI files.
I think Windows and nix have their places. Server work definitely seems more productive to me in a nix environment, but I think I'd jump off a cliff if I had to use it as my desktop environment day-in-day-out. The other problem is application lock-down; I can't blame the OS for that, but it's a reality... and using virtualization to run those applications seems to defeat the point to me. -
Installing Oracle Application Server 10.2 for Oracle Database Lite
Can anybody please tell me how to install oracle application server 10.2 for oracle database lite (i use oracle database lite for my final project). I use wi-fi connection to synchronize between pda and my laptop as server. Should i install oracle internet directory before installing oracle application server? I have difficulties in installing application server, what are the options should i take in every page of installation? Thanks before.
Install with the base, do not select any other options. Only choose webcache if you require the use of a software load balancer.

How to setup the SMTP server in Oracle apps?
Hi,
How to setup the SMTP server in Oracle Apps? Is it mandatory to keep the SMTP server on the same host where the Oracle data base is installed? Also can someone help how we can set up the SMTP server on different host (not the Database server) and we can use the same for Workflow notification mailer.
Thanks,

No, it is not mandatory. Also please note that the mails are sent out from concurrent manager mode. Not from the database node.

It depends on the operating system you are using. If you are using *nix then sendmail needs to be configured.

Where to download and how to install X Window System for Oracle Linux 5 ?
Folks,
Hello. I am using Oracle Linux 5 and Oracle Database 11g for PIA.
Before install Oracle DB 11g into Oracle Linux 5, we need to install X Window System according to the document page 2 http://download.oracle.com/docs/cd/B28359_01/install.111/b32285.pdf
But I don't know where to download and how to install X Window System for Oracle Linux 5.
Can any folk provide a link to download X Window System and tutorial to install it for Oracle Linux 5 ?You can address the problem in a number of different ways.
You can install X-windows from the installation DVD or setup access to the Oracle public software repository as described in http://public-yum.oracle.com. In which case, the command to install X-windows is: yum groupinstall "X Window System"
Or, you login remotely and and use SSH with X-forwarding, in which case the software on the server will use the X-Windows server on your client system. This is probably the preferred way since you do not have X-windows installed on the server. For more details about SSH forwarding and howto, please see Install Oracle 11gR2 on Ubuntu Linux 11.04 (64-bit) Howto part 2 Oracle Universal Installer. -
How To Find The Right Server........
Hi Friend�s I am Again Here
I Have A Question. I have Tool That�s Work is To Check The Duplicate CDR from Three day�s dump and Then Load this CDR�s in Database. I runt his tool on 2.4 GHz System with 1GB ram and I got the result
74 CDR�s /see Processing.
This time I Have A problem that I need server to run this tool and I am not getting that how I calculate the right server so that I can get the result upto 500 CDR�s/see
How Much CPU I need and How Much Ram I Needed. As per My Knowledge this can run fine on 2*2.4 GHz dual core CPU with 8GB ram.
Is it Fine,,,,,,,,,,,,,,,,,,,
Can anyone Help to Find Right System for this tool.Your post is hard/annoying to read. In English only the start of a sentence is capitalized. There is no need to capitalize every word within a sentence, unless required otherwise, like the pronoun "I" or the person/product names, e.g. "John Doe" and "Java".
Apart from that, your question has nothing to do with Java at all. Look for a CDR software forum or so. -
How outlook choose a CAS server
Hi all,
I would like to ask how outlook choose a CAS server? For example, if I have 2 sites to deploy exchange server, 1 in hk 1 in russia. How would outlook choose to connect to which CAS server for exchange 2010. For exchange 2013, should it be connected
to the active mailbox database copy? Thanks
Best Regards,
ElroyHi,
Client Access Server for Outlook provides the Autodiscover service, Web services (Autodiscover, availability and OAB) and RPC over HTTPS.
Outlook 2007 first searches for the SCP in AD which contains the URL to the Autodiscover service, if more than one SCP object is found in Active Directory which means there are mulitiple CAS servers in the Exchange organization. It will sort the list of
available SCPs by Site Affinity that match the site the Outlook's mailbox is located in. One of two lists is created, an in-site list or an out-of-site list. The list is not sorted in any particular order which is approximately in the order of oldest SCP records
(based on creation date) first. This is not related to the proximity. However, when retrieving the Web service (availability and OAB), It will decide which entry to return based on proximity and current availability. That means to contact Autodiscover maybe
use CAS which integrated with mailbox, and must use the CAS when retrieving other services.
Network Load Balancing is a supported method of doing this.
If there are mulitple CAS servers, for Outlook Anywhere (not logged into the domain), to even out the work load across multiple CAS servers which could offer Autodiscover services
Thanks & Regards

How to choose the right Mac Pro Specs?
Hello all,
Below is a question I posted in May along with someone's response. I'm wondering if I should still go with the response I received considering the new release of the mac pro 12 core. Did anything change that I need to note in my purchase or is the below response suitable? THANKS!!!!!
my question:
I need some help in choosing the right specs for my mac pro. I am looking for a computer that will help me in running my small business and keep my art portfolio organized. I'll probably be running several programs at a time (ex. mozilla, itunes, adobe bridge, dreamweaver, illustrator, and photoshop). More specifics below
What i'll be using it for:
building a few websites
managing my small business
large photo file editing
keeping business files, artist receipts, etc
cataloging my art portfolio (large photo files)
storing photos, music, and short videos
graphic design
infrequent film editing
infrequent sound editing
what programs i'll be using:
CS5 (mostly photoshop, illustrator, bridge, dreamweaver)
iphoto
itunes
maybe minimal finalcut/soundtrack pro
maybe minimal aftereffects
Advice?
My concerns are that it needs to run pretty smoothly with multiple programs open, no overheating, plenty of space for file storage and application support.
Hello washleyill,
My advice would be to buy the standard configuration 2.66GHz Quad Core (i.e. 3 x 1GB RAM, 640GB hard drive) from the Apple store, with the exception of the graphics card which you can buy as a CTO option for $200.00. It is well worth the upgrade from the GT120 - I know, because I upgraded myself last November after using a GT120 for 4 months.
With regard to the memory, if you can afford it now, buy 4 x 4GB from OWC now. If not, I would suggest that you buy 2 x 4GB now, and then add another 2 x 4GB in the future. 16GB of RAM is a much better option than 8GB for your requirements. You can sell the 3 x 1GB RAM to OWC in "part exchange", and there would be little difference in price for 2 x 4GB to the CTO option of 4 x 2GB.
http://eshop.macsales.com/shop/memory/Mac-Pro-Memory#1066-memory
Instead of buying 2 x 1TB hard drives as a CTO option, you could purchase 2 x 1.5TB or 2 x 2TB HDDs for less money, and you would still have the 640GB. Spare drives are always useful. I use my original 640GB as a spare emergency system boot drive (OS and applications) in an external enclosure.
Another alternative is to wait a few more weeks, in case the rumours of the introduction of a new Mac Pro range in June have any foundation.
Regards,
BillHello again washleyill,
The defining factor, which you haven't mentioned in either this or your original question, is what your overall budget is.
With the introduction of the new models, it's a new ball game now since I replied to your original question.
Now, if it is within your budget, I would recommend the 2010 Mac Pro 3.33GHz 6-Core "Westmere", with the standard 1TB hard drive, the basic 3 x 1GB RAM, but with the CTO Radeon HD5870 1GB Graphics Card.
This is the same configuration that Lloyd Chambers (of Mac Performance Guide fame) has recently ordered:
http://macperformanceguide.com/index.html
Then buy as much memory as you can afford now from OWC (trade-in the 3 x 1GB of Apple RAM against this):
http://eshop.macsales.com/shop/memory/Mac-Pro-Memory#1066-memory
(The 1333MHz is now listed on this page as well as the 1066MHZ)
If your budget is large enough, then certainly it is worth considering the 2.93Ghz 12-Core, but the 3.33GHz 6-Core, with maxed out memory and fast hard drives, should be more than adequate for your requirements. The more memory the better for Photoshop CS5!
I have just ordered Photoshop CS5 myself. It is a big step-up from Elements 8, and I was going to wait until next year, by which time, hopefully, any initial problems and bugs should have been resolved.
However, Adobe UK made me an offer I couldn't refuse! The full boxed Photoshop CS5 edition for half price!
Also, the offer included an option to buy Lightroom3 at the same time with a 30% discount off its normal price, and so I have taken the plunge and ordered that as well, because I have never been completely happy with Aperture (II or III). Normally, I would not have purchased both Photoshop CS5 and Lightroom 3, but at these prices the offer was too tempting.
Best of luck with your purchase,
Regards,
Bill -
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 -
