What's the best network for distributed processing?

Hey guys,
I have a network of three computers... I have distributed processing all set up on Compressor, and it runs really fast through the ethernet connection I have set up.
What's the absolute best way to set up this network?
The macbooks both have a firewire input, but that's not being used to transfer the data in this case... it's all ethernet.
The mac pro has 2 firewire ports... leaving one potentially open for a network.
Do you think it would be beneficial to set up a firewire network for these three computers, or is there any reason why a simple ethernet network is preferable?
Thanks in advance for all of your help...
Oh! One more question!
If I was going to set up a firewire network, how would I do it?

Hi MrWizard.. do you have Compressor.app V4.1? (Dec 2013) installed or the older ones.? According to you sign you're on older OSX 10.7.5.
The idea you post is sound HOWEVER... it's somewhat fickle and troubesome.. I'm assuming old V3.4 Compressor/Qmaster later ....
Hardware:
You can CERTAINLY use the Firewire ports as NETWORKS NIC using IP over FW.. It certain works between TWO macs as Ive used it yeas back..
Assume you have a FW hub or use the single FW HUB in the MACPRO ... or scout around for a fw switch 800 (if they exist!) or just use a FW800 to 400 cables and an cheap legacy FW400 hub... I saw one once in Taipei!
Simply on each configure the Firewrie INTERFACEs in the System Preferences / Network .... (+ add interface etc etc), apply
Either
hard code (manual) an IP address (1.1.1.x) for each,
Install and deploy OSX SERVER on your MACPRO (IP - 1.1.1.1) and set up a simple DNS and domain "mrwizards.cool_network" for that FW subnet (1.1.1.1x) then DHCP server for that subnet so that when the two MACBOOM PROS connect tey get a an IP address such as 1.1.1.2-253 and assign machine names. Set the dsn serahc on each machine to add 1.1.1.1 (your macpro to resolve machine names0. More work however easier to manage.
test your local DNS between the machines or TRACEROUTE / PING the machines from each other and verify the IP path over the FW NICs works ok.
as long as you can ascertain the IP traffic around your 1.1.1.x subnet the better.
Once you configure these as a separate NETWORK, you will need some way to provide FireWire however... this is only the start of your headaches. Im assuming you are on an olde Compressor/Qmaster V3.5 with legacy FCS 3 suite... true/false?
The configurations takes patience and trial and error and some clear understanding of what you are trying ot acheive if its really worth the effort.
TRANSCODING over nodal cluster: AKA DISTRIBUTED SEGMENTED MULTIPASS TRANSCODING!
ON paper you'd imaging the throughput would be worth it. Sadly the converse is true!.. it often takes LONGER to use a bunch of nodes rather than submission on a SINGLE machine using a CLUSTER on a single machine....
the elapsed time for the submission relies on the processing speed of the slowest machine and its network connection
final assembly of the quicktime peices for the object
hmmmm often quickier just to use a single CLUSTER on the MACPRO!.
You MAY want to consider this option assuming the hardware you have mentioned:
what about this instead of FireWre NICS?
USE Gbit ETHERNET allaround.
Steps:
Set the WIFI on the host to use the WIFI only network for you usual internal activities and bonjour (.local) etc.. assume low IP traffic. - all works oK
OPTION: on the MACPRO dedicate EN0 (first ethernet NIC to WIFI router). Turn off WIFI on MACPRO.
Utilise the ETHERNET (EN0 - builit in ethernet) on the MACBOOKs (older ones? .. will be very slow BTW)
connect the MACPRO Second ETHERNET, and the MACBOOk (pros?) ethenets to a cheap 8 x port Ethernet HUB switch ($HK150 / €15) they are all switches these days). This gives you an isolated subnet... no router needed. Plug in the hub/switch and power on!
look at step 3. above .. QUICK START: just hard code IP addresses as follows in each SYSTEM PREF/network):
MAC PRO ip 1.1.1.1
MACBOOK (Pro) #2 : ip address 1.1.1.2
MACBOOK (Pro) #2 : ip address 1.1.1.3
test the 1.1.1.1-1.1.1.3 network... (ping or traceroute)
V3.5 Compressor and Qmaster for ye old FCS - dig in to QMASTER PREFS as:
MACPRO - set servces and ALSO MAKE CONTROLLER., set NETWORK INTERFACE to the interface on the ETHERNET 2 (not all). set instances to more than 1 one instance but NOT max! Tick MANAGED SERVICES
MACBOO (pro)'s set servces only, set NETWORK INTERFACE to the interface on the ETHERNET (not all). set instances to more than 1 one instance but NOT max! Tick MANAGED SERVICES
launch APPLE QADMINISTRATOR.app and make a managed cluster - easy (DONT waste your time with Quickcluster!.. just dont)
IMPORTANT: make sure teh SOURCE and TARGETS of ALL the pbjects tha the transcodes will use are AVAILALBE (mounted and access) on ALL the machines that you want to participate.
set up batch and make sure SEGMENTED is ticked in the inspector..... submit the job
See how you go.
However if you have Compressor V4.1 (dec 2013) then just set your network up and it should just work with out all teh voodoo in the previous steps.
Post your results for others to see.

What is the best option for my process

Hi Gurus Can any one guide me which is the best available option for my business process.
in our client process We have a Final Product(say A). and two Vendors (say Vendor1 and vendor2)
This Final Product is made up of 3 other parts Lets say B,C and D.
So The client buys Product B and Product C from the Vendor1 and Product D from Vendor2
The vendor1 supplies the both the parts(A and B) to Vendor2.
The Vendor2 Takes the Parts B, C and Joins with Part D and deliver the final product A to the client.
There is no assembly cost for Vendor2- he charges for only part D.
Can anyone tell which is the best available option for my client.
Please help me ASAP
Thanks

Hi Amar,
There are many other factors that you need to take into consideration to define best approach for the process.
You have to know what type of control you want to have of the "production" of the product "A". Who is the owner of the components B and C while they are at vendor 2.
Who is the payer and how are you going to receive invoices of vendor 1 (you receive invoices for components according to the quantity of product A you receive in your company, or you receive invoices for all B and C received at vendor 2??)
Its no easy to give you a feedback without more information.

What is the best way for email processing setup on CRM 2013 (on- premises) Set up?

We need to notify customers via CRM 2013 for some activities.
I searched regarding email processing set up, and i found two options:
1. via outlook
2. Via Exchange Server.
Tried through email router (exchange server), but it requires exchange online or SMTP for outgoing profile.
I do have exchange on premise setup, I am not sure about SMTP option.
My queries are:
> Can we configure Exchange server to work as Exchange Online?
> what other option, I can try for email Processing?
looking for your suggestions...
Thanks in advance!

If you have Exchange onPremise, then you should be able to use the email router or server side sync in combination with CRM workflows (to generate the email). This is a fairly common scenario. You do not need Exchange Online.

What is the best network for an unlocked Iphone 5?

I have an unlocked IPhone 5.
Almost evey network I've been to told me that they don't offer 4G for unlocked IPhones.
AT&T said that I have to be on a contract and pay around $90/mo for an unlimited everything.
The issue is that I'm not that type of person who likes contracts...If I don't have the money to buy something in cash then I don't buy it, and i travel a lot; therefore, an IPhone5 5 has to be unocked for me.
currently I'm using H2O network which most people told me that they only claim that they provide 4G even though they don't...
So I would like to know what networks do you guys suggest? how much is it? and is it a real 4G?

Thanks, Meg.
So would a Verizon device-only iPhone 5S still be the better choice if I plan to use GSM in the US (and not the CDMA part of the Verizon iPhone which would lock me to their service).
Ideally, if I had the device in my hand, I would like to use TMobile's prepaid plan (40$ for unlimited talk, text, and 500 mb of data). Upon getting the phone, couldn't I just discard the included verizon simcard (without my activation) and just pop in the TMobile SIM card since the Verizon device-only instrument comes with the GSM unlocked? ( In other words, I don't have to ask Verizon to unlock the GSM part of the iPhone 5S )
Also, if this is what my goal is (to use a prepaid Tmobile sim), I could just buy an unlocked sim-free iPhone 5S from Apple, right? I dont have to ask for a Verizon device-only iPhone 5S if I want nothing to do with Verizon or use their CDMA service? I'm guessing a device-only iPhone 5s (regardless of carrier label) is the same as unlocked sim-free iphone 5S?

What is the best network for my small business?

Hi community! matt here, I'm new and looking to set up some buisines phones (11 in fact!) Has anyone had any experience with EE buisines? Are there any features which EE have which are useful? I'd particularly like to have a good interface to control all of he sims which I'm paying for and what each of them is using. Thanks very much,matt

I do use both MyEE online and through the app on my iPhone.
Personally I believe it could use a little more work, don't get me wrong; I have used worse online account management systems. However it does have all the important functionalities which you would expect and need from an account management system.
I use it to manage both my iPhone and a second data only SIM card.
I use it for the following reasons:
Enable and disable international roaming, international and premium calls and the ability to block users from purchasing additional data.
Check my itemised billing (this is provided to business customers FREE of charge).
Check my bill each month.
I've had to use for the following reasons in the past:
Check my price plan and what was included.
Check what active add ons were on my account.
What I personally find the most useful is, if you have more than one phone or SIM on your MyEE account, you can manage all of their settings in one convenient place.
You have the ability to:
Enable or disable data use (this stops the user from using any data).
Enable or disable the ability to purchase more data (this helps you manage your costs).
Enable or disable international roaming.
Enable or disable international and premium calls.

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 inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

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?

Please 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?

What is the Best practice for ceramic industry?

Dear All;
i would like to ask two questions:
1- which manufacturing category (process or discrete) fit ceramic industry?
2- what is the Best practice for ceramic industry?
please note from the below link
[https://websmp103.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000409682008E ]
i recognized that ceramic industry is under category called building material which in turn under mill product and mining
but there is no best practices for building material or even mill product and only fabricated meta and mining best practices is available.
thanks in advance

Hi,
I understand that you refer to production of ceramic tiles. The solution for PP was process, with these setps: raw materials preparation (glazes and frits), dry pressing (I don't know extrusion process), glazing, firing (single fire), sorting and packing. In Spain, usually are All-in-one solutions (R/3 o ECC solutions). Perhaps the production of decors have fast firing and additional processes.
In my opinion, the curiosity is in batch determination in SD, that you must determine in sales order because builders want that the order will be homogeneus in tone and caliber, and he/she can split the order in diferents deliveries. You must think that batch is tone (diferents colours in firing and so on) and in caliber.
I hope this helps you
Regards,
Eduardo

What's the best SSD for a Macbook Pro 13" Mid 2010?

Hello.
I will upgrade my 2010 Macbook Pro. I need to know what's the best SSD for my Macbook Pro. I was thinking about those:
- Kingston SSDNow V+200 (SVP200S37A/120G) - 120 GB
- CRUCIAL SSD M4 128 GB
- CORSAIR SSD Force Series GS 128 GB
- SAMSUNG SSD 840 Series Basic 2.5" - 120 GB (MZ-7TD120BW)
- CRUCIAL SSD interno Crucial v4 - 128 GB
Those are the easiest to find on Portugal.

It is my understanding that SATA III is backwards compatible to SATA II so that should not be an issue for your selection process.
As an aside, you might be interested to know that your MBP can now have 16 GB RAM installed.

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 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.

I hope Apple see fit to broaden this list, because, having thrown away several of those brands in my life, I now have a network compatble BROTHER printer that's awesome,
"There's an app for that," ie the BROTHER, but you can only print pictures and soforth.
Apple, step up, open up the list of printers we can use!
