What is the best platform for Oracle Server?

What is the best platform for Oracle Server?
What is your criterion?
Thanks,
Somsak B.

I believe that Oracle is developed and coded on a Solaris
platform and then ported to other operating systems. If that is
the case, you can assume that Solaris is the best platform or at
least the safest in terms of performance and risk.
If anyone knows anything to the contrary, pls correct me.

WHat is the best platform for SAP EP ?

Experts
Can any one help to share some information about what is the best platform for portal ?
Windows or UNIX
I have personally seen most of the customers are using windows as thier OS for Portal. When it comes to R3 BW SRM CRM and other application,its UNIX.
Interms of Performance , Windows is not right choice . I am not sure about life cycle management for the Windows.
A big advantage of using Windows hosting is that.NET technologies: ASP. NET, VB.NET easily works on these Hosts. If, the website is built using these technologies then opting a Windows server is most suitable
Microsoft Sharepoint is yet another application, which needs exclusive, Windows hosting. The only option available for users using this application is Windows server

Whats is the Best platform for CiscoWorks installation.

Hello,
Please advise whats the best platform for CiscoWorks installation. We are currently using the windows 2003 32-bit and CiscoWorks is slow.
We are currently using the LMS 3.2, RME 4.3.0, CM 5.2.1
THANKS

We are using 2008 R2 for LMS 4.0.1 - runs great - need loads of RAM and page file but we have not had many challenges. Java seems to run away with memory at times and we cycle out the services but it runs great.

What is the best book for Analysis Server 2012??

What is the best published book for SSAS 2012?

Thanks for the recommendation, Shankar! I would like to point out that the answer depends on what you mean by "SSAS 2012". Here are a few other recommendations...
If it's SSAS 2012 Tabular, then yes, "SQL Server Analysis Services 2012: The BISM Tabular Model"
is an option - but as a co-author I'm obviously biased! Teo Lachev's book, "Applied Microsoft
SQL Server 2012 Analysis Services: Tabular Modeling" covers some of the same ground and is also very good. If you're just interested in DAX, Rob Collie's book "DAX
Formulas for PowerPivot" is worth a look - even though it's for PowerPivot, the DAX language is the same as in SSAS Tabular.
For SSAS 2012 Multidimensional, because not much has changed since SSAS 2008, any book for 2008 or 2008 R2 will still be relevant. I haven't seen the 2012 edition, but editions of "Professional
Microsoft SQL Server 2012 Analysis Services with MDX and DAX" for older versions of SSAS were good general introductions; "Microsoft
SQL Server Analysis Services 2008 Step-By-Step" is also good. For more experienced developers there's another book I co-wrote, "Expert
Cube Development with SQL Server 2008" (a refresh for SSAS 2012 is coming later this year); and for the really advanced SSAS developer who wants to understand the internals of the product there's "Microsoft
SQL Server 2008 Analysis Services Unleashed", written by Edward Melomed and several other senior members of the SSAS dev team at the time. For MDX beginners I'd recommend "Microsoft
SQL Server 2008 MDX Step--By-Step", and for more advanced MDX there's "MDX with Microsoft
SQL Server 2008 R2 Analysis Services Cookbook".
For the whole Microsoft BI stack, Brian Larson's books are always good (eg "Delivering Business
Intelligence with SQL Server 2012") and cover more than just SSAS, although they go into less detail.
HTH,
Chris

What are the BEST books for Oracle database architect/designer?

What concrete books would you recommend for OLTP database developer (to start from the scratch, starting from data sources analysis, logical and physical data modeling, indexes, tuning, maintaining). It doesn't have to be a book particulary for Oracle but suitable for it..
I don't mean books DBA's or overall Oracle handbooks, also not for OLAP.
Thanks!

For learning how to use Oracle database effectively, i would say
Tom Kyte's both books:
Effective Oracle by design
& Expert Oracle Database Architecture
Jonathan Lewis's
Practical Oracle 8i
They tell you all the stuff: what/how to do something? and most importantly what/how not to do ?
And their writing style is just awesome :)

What's the best approach for handeling about 1300 connections in Oracle.

What's the best approach for handling about 1300 connections in Oracle 9i/10g through a Java application?
1.Using separate schema s for various type users(We can store only relevant data with a particular schema. Then No. of records per table can be reduced by replicating tables but we have to maintain all data with a another schema Then we need update two schema s for a given session.Because we maintain separate scheama for a one user and another schema for all data and then there may be Updating problems)
OR
2. Using single schema for all users.
Note: All users may access the same tables and there may be lot of records than previous case.
What is the Best case.
Please give Your valuable ideas

It is a true but i want a solution from you all.I want you to tell me how to fix my friends car.

What is the Best Practice for Server Pool...

hi,
wht is the Best Practice for having server pool i.e
1) having a single large serverpool consisting of "n" number of guest vm
2) having a multiple small serverpool consisting of less of number of guest vm
please suggest.....

Raja Kondar wrote:

2) having a multiple small serverpool consisting of less of number of guest vm I prefer option 1, as this gives me the greatest amount of resources available. I don't have to worry about resources in smaller pools. It also means there are more resources across the pool for HA purposes. Not sure if this is Official Best Practice, but it is a simpler configuration.
Keep in mind that a server pool should probably have up to 20 servers in it: OCFS2 starts to strain after that.

What is the best artical for understanding Data Pump

Hi,
What is the best artical for understanding the relationship / dependency of NETWORK_LINK with FLASHBACK_SCN or FLASHBACK_TIME .
Why it is manditory to have NETWORK_LINK , when we are using FLASHBACK_SCN or FLASHBACK_TIME.
Can some one explain the internal for that dependency
Thanks
Naveen

There's no direct dependency between NETWORK_LINK and FLASHBACK_SCN and FLASHBACK_TIME
As noted in this Oracle doc,
If the NETWORK_LINK parameter is specified, the SCN refers to the SCN of the source database
FLASHBACK_SCN and FLASHBACK_TIME are mutually exclusive.

What is the best antivirus for MacBook Pro?

What is the best antivirus for MacBook Pro?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

What are the installation steps for Oracle Fusion HCM

Hi all
I will like to ask, what are the installation steps for Oracle Fusion HCM as well as can it work on Windows or only on virtual machine?
Thanks

If you're looking to install Fusion HCM, your best bet is to install on linux, eg, Oracle Enterprise Linux. It's up to you whether you put that in a Virtual Machine or not. I don't think Windows is an available platform for Fusion Apps at the moment, although am prepared to be corrected if you find anything to the contrary!
If you're looking to do an install on your own PC/laptop, you're probably out of luck - you'll be needing around 128GB of RAM. Check out this post:
http://onlineappsdba.com/index.php/2011/11/02/fusion-applications-128-gb-memory-and-500-gb-disk-space-are-you-ready/

Hi Gina D 3333,
Best-practice file-naming conventions for PDF files are the same as for any other file. I found this article on Apple's website that contains some useful pointers to consider when you're naming files that will be used on multiple platforms: OS X: Cross-platform filename best practices and conventions
I hope this helps!

What are the best approaches for mapping re-start in OWB?

What are the best approaches for mapping re-start in OWB?
We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
We have number of mappings. We built process flows for mappings as well.
I like to know, what are the best approches to incorportate re-start options in our process. ie a failure of mapping in process flow.
How do we re-cycle failed rows?
Are there any builtin features/best approaches in OWB to implement the above?
Does runtime audit tables help us to build re-start process?
If not, do we need to maintain our own tables (custom) to maintain such data?
How did our forum members handled above situations?
Any idea ?
Thanks in advance.
RI

Hi RI,
How many mappings (range) do you have in a process flows?Several hundreds (100-300 mappings).
If we have three mappings (eg m1, m2, m3) in process flow. What will happen if m2 fails?Suppose mappings connected sequentially (m1 -> m2 -> m3). When m2 fails then processflow is suspended (transition to m3 will not be performed). You should obviate cause of error (modify mapping and redeploy, correct data, etc) and then repeat m2 mapping execution from Workflow monitor - open diagram with processflow, select mapping m2 and click button Expedite, choose option Repeat.
In re-start, will it run m1 again and m2 son on, or will it re-start at row1 of m2?You can specify restart point. "at row1 of m2" - I don't understand what you mean (all mappings run in Set based mode, so in case of error all table updates will rollback,
but there are several exception - for example multiple target tables in mapping without corelated commit, or error in post-mapping - you must carefully analyze results of error).
What will happen if m3 fails?Process is suspended and you can restart execution from m3.
By having without failover and with max.number of errors=0, you achieve re-cycle failed rows to zero (0).This settings guarantee existence only two return result of mapping - SUCCSES or ERROR.
What is the impact, if we have large volume of data?In my opinion for large volume Set based mode is the prefered processing mode of data processing.
With this mode you have full range enterprise features of Oracle database - parallel query, parallel DML, nologging, etc.

What is the best resource for Discoverer novice.

I need direction in this tool. what is the best resource for me to use.

Hi Ade
You could do a lot worse than get hold of a copy of the Oracle Discoverer 10g Handbook that I wrote. It will walk you through much of what you need to know. You can find it on amazon.com or via a link from my website: http://learndiscoverer.com/books/books.htm
Another good resource would be a training class in either the Admin tool or End User tool or both. Oracle Corporation offer excellent training as do many other companies, including mine. Just google Discoverer Training.
Further resources are the Oracle By Example series on the OTN forum. These are free. You will find the Discoverer lessons here: http://www.oracle.com/technology/obe/obe_bi/discoverer/discoverer_1012/index.html
Other resources, such as blogs, abound on the web too. Here are some:

What is the best app for backing up my mac. I do publication work and need to save my work?

what is the best app for backing up my mac. I do publication work and need to save my work?

My answer does not have the black Apple logo but the hardearned black belt of (bad) experience.
There is one problem with TimeMachine. It can get corrupted out of the blue with no warning and it will not want to restore correctly (as an added "bonus" you get to find this out the "hard" way, when you need it most). Plus it takes ages for the data to be copied back, sometimes days. Haven't tried my 600gb backup on Mavericks but Mountain Lion had this knack of breaking Timemachine after a couple of months.
To back up my entire server is use SuperDuper. It mirrors the drive to an external one (usb for example) The cool thing is you can use that usb drive and start the OS X from it (by holding Alt when you hear the boot chime).
This way you have a working copy of your entire machine. You can even go to another mac and boot it from there. I literally ran the OS X Server in my company from a usb drive on an old MacBook Pro until i got around to fix the problems with the actual server machine.
This has saved me twice already as the Hitachi drives Apple uses, tend to die like clockwork after 4000-5000 hours of use with no warning.
http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
PS. As a sidenote... SSDs are more reliable than a normal HDD (not to mention faster) I can't stress this enough, my Server is on two SSDs now. I can't tell you how stress free the setup is, it doesn't feel like a computer but more like a router, it just works... forever. After two years with SSDs my server has had two days of downtime and their health is at 97%, they will literally last 100 years with normal use. I'd go so far as to recommend you buy an SSD and move your old HDD to an external enclosure and use that as a usb backup. (for SSDs i use Plextor / Lite-On M3s (older) or the M6s (newer))
