annoying replies. You want me to browse all the post
two weeks ago to find what im looking for. stoopsMost regulars to this forum find X-posting annoying. Since you are lazy and want me to search the posts of the last couple of week for you, I find you very annoying.

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 SeftonI 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? -
Hi,
We are about to start a new project using Technologies like Spring and JSF. I am looking for some IDE which provide us Drag and Drop support for JSF components.
Moreover, the IDE is plugable with third party JSF components. So that all those component are available at Design Time.
Till now, i am thinking for Sun Creator, but i am looking for suggestions.Hi Ali,
I would suggest you go with NetBeans IDE 5.5 and using Visual Web. If you want to use Spring Framework, you can also do that because plugin for spring framework is available too.
I've recently created my project which was using EJBs and I found NetBeans a single IDE to develop complete enterprise application. -
I am looking to start developing apps for the iTunes Store, but I have no previous experience. What is the best way for me to start on this? As in which programs and materials must I need and what I need to know. Thanks!
You will need a Mac, with OS X 10.6+ on it, to be able to develop iOS apps.
There is some info on these pages :
developer site : https://developer.apple.com
developing for iOS 7 : https://developer.apple.com/ios7/
developer support : https://developer.apple.com/support/
developer forums : https://devforums.apple.com/index.jspa (you will need to be a registered developer to access them) -
my daughter is a college student. she needs to write and compile c programs on her mac for a class this semester. what is the best place for her to start to get the correct compiler etc. to use ? thanks
If you know that you will not be asked to design GUI interfaces, and the C programming course will adhere to command line compilation environments, then get the Xcode command-line developer tools, and skip the extra complication of Xcode until you absolutely need it. Apple has kicked GNU C to the curb and is rightly so, using Clang/LLVM compiler technology.
Sign up for a free Apple Developer account using your Apple ID, and then visit the Mac Dev Center, and towards the bottom of the page, you will see additional downloads. Click on the associated, all down loads link. Know your OS X version beforehand, as the command-line tool releases are tied to general operating system versions, and the most recent Xcode version. That said, there are currently two March 9, 2015 command-line tools for Xcode 6.2 — one for OS X 10.9 Mavericks, and the other for OS X Yosemite. -
What is the best solution for running windows based programs
I have one program that I need windows for. What is the best solution for doing this without painfully slowing down my mac.
Depends on your needs.
BootCamp requires reboot and uses all physical resources of the system. Only OSX *or* Windows can run. Better for gaming or memory intensive tasks. BootCampAssistant must set up the boot sector to make it work. Also BCA required to remove it.
VM (virtual machine) like Parallels which "hosts" Windows while still running OSX. You split RAM between the two environments. VM is just another program so no special boot sector changes needed, but not good for graphics or RAM intensive programs.
Other recommended alternates to Parallels (paid) are VM Fusion (paid) and VirtualBox (free download from Oracle.com). -
My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?
Rich PPlease follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

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 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.
RIHi 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.

I have a MacBook Air (13", 1.7GHz, 8GB RAM, 500GB SSD) that I'll be using to play sound files (primarily organ and piano) for worship services at my church. We'll be using a QSC RMX2450 650 Watts/Channel amplifier with Community CPL-27 speakers and also a JBL SUB 250P powered subwoofer with its own amplifier. What's the best option for getting sound out from the Mac to both of these amplifiers?
if you work with own recorded sounds you might wanna have a music program where you want to work with samples, steinberg has got very good ones (so they say)... but their really really ( ²) expensive(that's why almost no one haves them), magix haves good ones too bu their more for 'unprofessional' use, ableton haves really good ones too and they're not to difficult to use (if you know a bit of those programs you learn very quickly) and if you don't get them, there is a sort of manual built in it which explains and lets you do things to start (basics)
i hope this helped, btw stereo speakers are always better if you buy good ones (no pc speakers), but if you don't think you need them, don't buy them...
so again, i hope you have some ideas now -
What are the best tools for converting .shg files to HTML image maps?
After trying several different ways to import our WinHelp
project into RH HTML, I'm left with recreating the project in HTML.
There are over 200 .shg files. What's the best tool for converting
them? Is there a free program that converts them? Or is there a
better way?
LaconaYes, I have not been able to import the .hlp file, which was
my last posted question/issue. I have tried creating a Microsoft
HTML layout in RH4 Word; it begins to compile and, somewhere in the
process, just freezes. I've tried importing the .hlp file into RH
HTML; same result. I've tried creating a new HTML project with the
.hlp file; same result. If I could import the file, it'd be great.
Otherwise, I'll need to recreate the entire project, which brings
me to converting the .shg files. Any ideas? -
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
NaveenThere'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 solution for me to run Microsoft Access on my brand new iMAC? Assume I'm a casual user.
I am lead to believe by some real smart guys on the Apple site that If I have the Apple Store partition my iMAC and add the full suite of Office products on that partition, I can run the few Access programs I have and need to run.
Comments encouraged. Thank you in advance for your consideration and help.You would have to install Windows, then install Microsoft Office Professional for Windows on it To install Windows you will have to choose between Boot Camp (faster, free) and a Virtual Machine (simpler, slower, easier to backup)
You should try LibreOffice (free), it can open Access files, it may not have all Access's feature set though, worth a try.
