The best AP for large warehouse deployment ?

Hi,
Hope you peeps can assist.
New design / installation at a warehouse....
What is the best / recommended AP for a warehouse with shelving 10m high and 1.8m appart and a ceiling at about 11.5m? Warehouse is 129m x 97m, about 60% of the floor will be shelving and the rest offices with a ceiling of 3m.
My concern is the area where the shelving will be utilized and scanners to be used for stock control. The goods on the shelves will differ from plastics to metal in wooden crates and normal boxes.
Thank you in advance for your advice and recommendation. Please also state whether you recommend internal or external antennae.
David

That is hard to tell you exactly what you need to do, but for that height, I would use an external antenna, the office if fine with internal. I would use either the 3702e or 2702e for the install. Most of my clients in the manufacturing/distribution has gone with the 3702e's.

Is OWB the Best Tool for Designing Warehouse Tables?

My current site uses OWB for ETL but mandates the use of TOAD Data Modeller for design and build of the warehouse tables.
I always thought that OWB could do this task just as well as TOAD, but I'm not very experienced with OWB.
Can anyone advise?

You can design table with OWB and deploy to database, but is better create database objects [tables, views ets.] with SQL by DDL script and import this objects to OWB.
You can define physical properties, keys, constraints, partitions, indexes, grants ets. for one table in one SQL-script.

What are the best solutions for data warehouse configuration in 10gR2

I need help on solutions to be provided to my Client for upgrading the data warehouse.
Current Configuration: Oracle database 9.2.0.8. This database contains the data warehouse and one more data mart on the same host.Sizes are respectively 6 Terabyte(retention policy of 3 years+current year) and 1 Terabyte. The ETL tool and BO Reporting tools are also hosted on the same host. This current configuration is really performing poor.
Client cannot go for a major architectural or configuration changes to its existing environment now due to some constraints.
However, they have agreed to separate out the databases on separate hosts from the ETL tools and BO objects. Also we are planning to upgrade the database to 10gR2 to attain stability, better performance and overcome current headaches.
We cannot upgrade the database to 11g as the BO is at a version 6.5 which isn't compatible with Oracle 11g. And Client cannot afford to upgrade anything else other than the database.
So, my role is very vital in providing a perfect solution towards better performance and take a successful migration of Oracle Database from one host to another (similar platform and OS) in addition to upgrade.
I have till now thought of the following:
Move the Oracle database and data mart to separate host.
The host will be the same platform, that is, HP Superdome with HP-UX 32-bit OS (we cannot change to 64-bit as ETL tool doesn't support)
Install new Oracle database 10g on the new host and move the data to it.
Exploring all new features of 10gR2 to help data warehouse, that is, SQL MODEL Clause introduction, Parallel processing, Partitioning, Data Pump, SPA to study pre and post migrations.
Also thinking of RAC to provide more better solution as our main motive is to show a tremendous performance enhancement.
I need all your help to prepare a good road map for my assignment. Please suggest.
Thanks,
Tapan

What is the best practice for setting up warehouse inventory for oil & gas tank farm

Hi, i want to know the best practice for setting up warehouse inventory for oil & gas tank farm. SAP has these levels for inventory management in warehouse environment: warehouse-aisle-shelf-bin. To me the bin seems to be the central location for inventory. So do i set up each oil tank as a bin location?

Hi,
In order to be able to suggest you a database product, we need to know more details on what your application's needs are and on what operating system you use.

Hi all! What is the best way to create the correct space for baseball jersey names and numbers? along with making sure they are the right size for large printing.

What is the best way to create the correct space for baseball jersey names and numbers? along with making sure they are the right size for large printing.

Buying more hard drive space is a very valid option, here. Editing takes up lots of room, you should never discount the idea of adding more when you need it.
Another possibility is exporting to MXF OP1a using the AVC-I codec. It's not lossless, but it is Master quality. Plus the file size is a LOT smaller, so it may suit your needs.

What is the best practice for AppleScript deployment on several machines?

Hi,
I am developing some AppleScripts for my colleagues at work and I don't want to visit each of them to deploy my AppleScript on their Macs.
So, what is the best practice for AppleScript deployment on several machines?
Is there an installer created by the Automator available?
I would like to have something like an App to run which puts all my AppleScript relevant files into the right place onto a destination Mac.
Thanks in advance.
Regards,

There's really no 'right place' to put applescripts. folder action scripts nees to go in ~/Library/Scripts/Folder Action Scripts (or /Library/Scripts/Folder Action Scripts), anything you want to appear in the script menu needs to go in ~/Library/Scripts (or /Library/Scripts), script applications should probably go in the Applications folder, but otherwise scripts can be placed anywhere. conventional places to put them are in ~/Library/Scripts or in a subfolder of ~/Library/Application Support if they are run by an application. The more important issue is to make sure you generalize the scripts: use the path to command to get local paths rather than hard-coding them in, make sure you test to make sure applications or unic executables you call are present ont he machine, use script bundles rather tna scripts if you scripts have private resources.
You can write a quick installer script if you want to make sure scripts go where you want them. Skeleton verion looks like this:
set scriptsFolder to path to scripts folder from user domain
set scriptsToExport to path to resource "xxx.scpt" in directory "yyy"
tell application "Finder"
duplicate scriptsToExport to scriptsFolder with replacing
end tell
say "Scripts are installed"
save this as a script application, then open the application pacckage and create a folder called "yyy" in the resources folder and copy your script "xxx.scpt" into it. other people can run the app to install the script.

Which is the best way for posting a large number of records?

I have around 12000 register to commit to dababase.

I meant RECORDS instead of REGISTERS.Maybe that is where you are going wrong, records are for putting on turntables.

What is the best software for burning a large slideshow with 500 photos and music to DVD?

What is the best software for burning a large slideshow with 500 photos and music to DVD?

Are you talking about strictly burning an already put-together slideshow or composing one and then burning it?
My all time favorite slide show maker is Photo to Movie; you can then burn it from there or get it into iMovie and/or iDVD for the "finishing" touch. My favorite burn software is Toast, although you can use iMovie, iDVD, and Finder as well.

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.

Where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable.

where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable. Thank you.

How to maintain a Mac
1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
If storage space is running low, use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

What are the best practices for generating an EPS logo from InDesign?

Our costomer is running into technical issues with the logo we sent them, which was exported from Indesign. Images were not embedded and fonts missing. I was able to embed the images and fonts. However, we DO NOT want them to be able to make any text changes. So after exporting an eps, I opened the file in Adobe Illustrator and made all the text outlines. I hope this works. But I just wanted to post the question on what are the best practices for doing this?
The client needs the logo with transparent background, images emebdded and type in outlines. Also, they need some space around the text. When I exported the eps, the file is right up on the edge of the type.

It sounds like you are pretty far from "best practice" with regard to logo design and delivery.
These days, the very use of the EPS format should be considered bad practice, and some other terms in your post, (i.e., 'images,' 'missing fonts'), make it sound like there is not a seasoned logo designer involved.
That said, you probably already got the advice you need to get out of the immediate jam. However, without proper logo design, you and the client will soon be facing other problems. You should be delivering a 100% vector graphic in single-color (black) and corporate-color(s) versions, with no live font data, that has been test-scaled to very small and very large sizes; ensuring it will work at postage-stamp size and on the side of a truck or building, with specific spot color(s) and proportions that will enable it to be offset printed, embroidered and screen-printed on apparel, and cut into signage materials and decals.

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.....

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's the best way for home sharing to iDevices without iTunes?

What's the best way for home sharing movies and tv shows on my iDevices? I know I can use home sharing through iTunes, but I'm looking for a way to share videos to my iDevices without having to leave my computer on. I have a MacPro, iPhone, iPad, Airport Extreme, and Airport Express (and several external hard drives). Can anyone suggest an app that would do this? Can I have videos on an external hd attached to an Airport Extreme/Express and have it stream without iTunes?

If your "server" is new enough to run Mountain Lion, you can purchase the OS X Server app from the Mac App store and you'll have everything you need to host a NetInstall (NetBoot) server.
If your machine does not support Mountain Lion, you'll need to purchase the appropriate Mac OS X Server software (i.e. Lion Server or Snow Leopard Server)
From there you can host NetInstall or NetRestore images, depending on your preferred workflow, which can be created using System Image Utility.
As Richard points out you can also use Deploy Studio which, again depending on your preferred workflow, might simplify things.

What is the best app for animation for big screen - Flash?

I am working on a project that requires multiple animations that will be projected on a large outdoor screen. Edge Animate looks very easy to use, but looks like it only exports to html? Am I correct in assuming that Flash is probably the best choice for creation, and then doing my edits in premiere?

Flash Pro CC has a export video feature to export your content in full high-definition video and audio:
