What is best practice for multi camera edit with differing lengths?

I have three cameras that took video of an engagement party. Camera A and B took it all (with some early extra material exclusive to each camera). Camera C took some, then stopped, then took more.
So I have four sets of clips - A and B which are complete, then C then D.
Should I create sequence 1 with A, B and C synchonised, then create sequence 2 with A, B and D synchronised, then sequence 3 with sundry early non-multi camera clips, plus sequence 1 plus sequence 2 then late non-multi camera clips?
Or can I synchronise A, B and C, then on the same timeline synchronise A, B and D? I'm concerned that the second synchronisation will put C out of sync.
What is the best way to approach this?
Thanks in advance.

A and B which are complete, then C then D.
I think you're looking at this in the wrong way. You have only three cameras, A, B and C, but you don't really have a D camera, as those are just other clips from camera C. You might call them C1 and C2 if you like, but calling them D seems to be confusing the issue, as it's still only three cameras, and three shots to choose from when cutting the sequence. (Except for the gap between C clips, where you will have only the A and B shots to choose.)
You can absolutely sync all the clips form camera C on the same sequence as A and B. And it will probably be easier to do so.

What is best practice for using a SAN with ASM in an 11gR2 RAC installation

I'm setting up a RAC environment. Planning on using Oracle 11g release 2 for RAC & ASM, although the db will initially be 10g r2. OS: RedHat. I have a SAN available to me and want to know the best way to utilise that via ASM.
I've chosen ASM as it allows me to store everything, including the voting and cluster registry files.
So I think I'll need three disk groups: Data (+spfile, control#1, redo#1, cluster files#1), Flashback (+control#2, redo#2, archived redo, backups, cluster files#2) and Cluster - Cluster files#3. So that last one in tiny.
The SAN and ASM are both capable of doing lots of the same work, and it's a waste to get them both to stripe & mirror.
If I let the SAN do the redundancy work, then I can minimize the data transfer to the SAN. The administrative load of managing the discs is up to the Sys Admin, rather than the DBA, so that's attractive as well.
If I let ASM do the work, it can be intelligent about the data redundacy it uses.
It looks like I should have LUN (Logical Unit Numbers) with RAID 0+1. And then mark the disk groups as extrenal redundancy.
Does this seem the best option ?
Can I avoid this third disk group just for the voting and cluster registry files ?
Am I OK to have this lower version of Oracle 10gr2 DB on a RAC 11gr2 and ASM 11gr2 ?
TIA, Duncan

Hi Duncan,
if your storage uses SAN RAID 0+1 and you use "External" redundancy, then ASM will not mirror (only stripe).
Hence theoretically 1 LUN per diskgroup would be enough. (External redundancy will also only create 1 voting disk, hence only one LUN is needed).
However there are 2 things to note:
-> Tests have shown that for the OS it is better to have multiple LUNs, since the I/O can be better handled. Therefore it is recommended to have 4 disks in a diskgroup.
-> LUNs in a diskgroup should be the same size and should have same I/O characteristica. If you now have in mind, that maybe your database one time will need more space (more disks) than you should use a disk size, which can easily be added, without waisting too much space.
E.g:
If you have a 900GB database then does it make sense to only use 1 lun with 1TB?
What happens if the database grows, but only grows slightly above 1TB? Then you should add another disk with 1TB.... You loose a lot of space.
Hence it does make more sence to use 4 disks á 250GB, since the "disks" needed to grow the disk groups can be extended more easily. (just add another 250G disk).
O.k. there is also the possibility to resize a disk in ASM, but it is a lot easier to simple add an additional lun.
PS: If you use a "NORMAL" redundancy diskgroup, then you need at least 3 disks in your diskgroup (in 3 failgroups) to be able to handle the 3 voting disks.
Hope that helps a little.

What is best practice for calling XI Services with Web Dynpro-Java?

We are trying to expose XI services to Web Dynpro via "Web Services". Our XI developers have successfully generated the WSDL file(s) for their XI services and handed off to the Web Dynpro developers.
The Java developers put the WSDL file to their local PC's and import as "Adaptive Web Services" data models. When the application is constructed and deployed to our development box, the application abends because the J2EE server on that box cannot locate the WSDL file at runtime (it was on the developers box at, say, "C:\temp\" and that directory does not exist on the dev server).
Since XI does not have a way of directly associating the generated WSDL file to the XI service, where is the best place to put the WSDL so it is readable at design time and at run time? Also, how do we reconcile that we'll have 3 WSDL files for each service (one for Dev, one for QA and one for Prod) and how is the model in Web Dynpro configured so it gets the right ome?
Does anyone have any good guide on how to do this? Have found plenty of "how to consume a Web Service in Web Dynpro" docs on SDN, but these XI services are not really traditional Web Services so the instructions break down when it comes time to deploy.

HI Bob,
As sometimes when you create a model using a local wsdl file then instead of refering to URL mentioned in wsdl file it refers to say, "C:\temp" folder from where you picked up that file. you can check target address of logical port. Due to this when you deploy application on server it try to search it in "c:\temp" path instead of it path specified at soap:address location in wsdl file.
Best way is re-import your Adaptive Web Services model using the URL specified in wsdl file as soap:address location.
like http://<IP>:<PORT>/XISOAPAdapter/MessageServlet?channel<xirequest>
or you can ask you XI developer to give url for webservice and username password of server

What's best practice for logging messages in pageflow?

What's best practice for logging messages in pageflow?
Workshop complains when I try to use a Log4J logger by saying it's not serializable. Is there a context similar to JWSContext that you can get a logger from?
There seems to be a big hole in the documentation on debug logging in workflows and JSP pages.
thanks,
Rodger...

Make the configuration change in setDomainEnv.cmd. Find where the following variable is set:
LOG4J_CONFIG_FILE
and change it to your desired path.
In your Global.app class, instantiate a static Logger like this:
transient static Logger logger = Logger.getLogger(Global.class);
You should be logging now as long as you have the categories and appenders configured properly in your log4j.xml file.

What is best practice for installing Yosemite

I am currently on OS X Mavericks version 10.9.5 Macbook pro 13. 2.6 ghz intel for i5, 8gb 1600 mhz ddr3.
I am now downloading yosemite 10.10.1 but since i've been reading all these negative feedback so far, i am having second thoughts if i should continue to install the upgrade or not.
Any suggestion What is best practice for installing Yosemite? Or is it not yet time to upgrade since the platform is premature yet?
Thanks in advance.

Check your apps are compatible with 10.10 - roaringapps.com
http://www.etresoft.com/etrecheck can show what is running & installed - look for updates on the developer own sites.
If you have many kernel extensions or startup items look for updates to them too
Take a full bootable backup to another disk via Carbon Copy Cloner, Super Duper! or Disk Utility
Disconnect the backup before you begin any install (ideally set it aside & leave it untouched incase you need to go back to 10.9)
Personally I prefer a clean install when there are signs of multiple migrations (if you have upgraded several OS for a period of years). Setup Assistant/ Migration Assistant can import user data from a backup, but consider that Apps & 'other data' should be manually reinstalled from the latest versions.
If you clean install (erase the HD before installation) then make sure you deauthorise iTunes & any other apps that are associated online (like find my Mac).

What are best practices for managing my iphone from both work and home computers?

What are best practices for managing my iphone from both work and home computers?

Sync iPod/iPad/iPhone with two computers
Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans withiTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entires and import the local content you have on that box.

Best practice for integrating oracle atg with external web service

Hi All
What is the best practice for integrating oracle atg with external web service? Is it using integration repository or calling the web service directly from the java class using a WS client?
With Thanks & Regards
Abhishek

Using Integration Repository might cause performance overhead based on the operation you are doing, I have never used Integration Repository for 3rd Party integration therefore I am not able to make any comment on this.
Calling directly as a Java Client is an easy approach and you can use ATG component framework to support that by making the endpoint, security credentials etc as configurable properties.

Multi Camera Editing with Matrox CODEC ( VS4 ) Card

Hello All.
Setup
I am recording 4 inputs from the Matrox VS4 via Wirecast 4.2 and also tried 5.0
- 1080i @ 100Mbps
- All the video footage play perfectly with no problems what so ever
- I Have installed the Matrox VFW Software Codecs of a system which DOES NOT have the VS4 card
- I can edit 1 video with NO PROBLEM.
Problem
- Using Adobe Premiere 7.1 CC with multi camera editing, the footage is jittery after a few seconds.
- Using Adobe Premiere CS 6.0 with multi camera editing, the footage is jittery after a few seconds.
- I have tried with 2 cameras up to 4 cameras and I get the same problem.#
Other Test
- I have tried 12 x videos which are MP4 in multi camera editing with NO PROBLEMS!!!
- I am using 4 x 128GB SSD in RAID 0 ( 1450 MB/s) - Through put is not an issue.
- I have also reduced the MB/s on the ISO capture of 50MB/s
This is the CODEC you need to have installed on your computer in order to edit the view/edit the videos recorded by the Matrox VS4:
http://www.matrox.com/video/en/support/windows/vfw_software_codecs/downloads/softwares/ver sion1.0/
The Matrox Video for Windows (VFW) software codecs let you render and play back Matrox .avi files in your VFW programs without having Matrox video hardware installed. This version provides codecs that were previously available only on systems that have particular Matrox video hardware, such as Matrox Axio. This includes the Matrox DVCPRO HD codec, and "+ Alpha" versions of the Matrox uncompressed and MPEG-2 I-frame codecs. As well, the Matrox VFW MPEG-2 I-frame HD codec now lets you render and play back Matrox MPEG-2 I-frame .avi files in all HD formats (720p, 1440x1080i/p, and full-size 1080i/p).
The following VFW software codecs are provided for use on 32-bit and 64-bit Windows operating systems:
Matrox DV/DVCAM
Matrox DVCPRO
Matrox DVCPRO50
Matrox DVCPRO HD
Matrox MPEG-2 I-frame in SD and HD resolutions, with or without alpha
Matrox Uncompressed in SD and HD resolutions, with or without alpha
Matrox Offline HD
Matrox M-JPEG and HDV (playback only)
Is this an issue that is present the Premier 7.1 CC or the CODEC or even both?
Thank you all.

What is best practice for conditional rendering?

i have a set of radio buttons that conditionally render another set, which in turn conditionally render a 3rd set.
i am doing this by using a valueChangeListener on an h:selectOneRadio
when i click yes on the 1st set it renders the 2nd set.
when i click yes on the 2nd set it renders the 3rd set.
when i click no on the 1st set now it correctly removes the 2nd & 3rd sets, the method also nulls the values.
when i click yes on the 1st set, it renders the 2nd set with the old values even though they were nulled. and i can see in the debugger they are still null.
so there seems to be an issue updating the model, but i dont know what that issue is. im sure it just has something to do with the way i am trying this conditional render. please see below for my first field and my valueChangeListener method.
any help with what is a best practice for this scenario would be greatly appreciated.

Similar issue is covered and explained here: [http://balusc.blogspot.com/2007/10/populate-child-menus.html]. Not sure if it solves your problem as you're using ajax4jsf whereas I don't, but it might give new insights. To the point you might need to bind the component(s) and use setValue(null) or setSubmittedValue(null).

What are best practice for packaging and deploying j2EE apps to iAS?

We've been running a set of J2EE applications on a pair of iAS SP1b for about a year and it has been quite stable.
Recently however we have had a number of LDAP issues, particularly when registering and unregistering applications (registering ear files sometimes fails 1st time but may work 2nd time). Also We've noticed very occasionally that old versions of classes sometimes find their way onto our machines.
What is considered to be best practice in terms of packaging and deployment, specifically:
1) Packaging - using the deployTool that comes with iAS6 SP1b to package is a big manual task, especially when you have 200+ jsp files. Are people out there using this or are they scripting it with a build tool such as Ant?
2) Deploying an existing application to multiple iAS's. Are you guys unregistering old application then reregistering new application? Are you shutting down iAS whilst doing the deployment?
3) Deploying ear files can take 5 to 10 mins, is this normal?
4) In a clustered scenario where HTTPSession is shared what are the consequences of doing deployments to data stored in session?
thanks in asvance for your replies
Owen

You may want to consider upgrading your application server environment to a newer service pack. There are numerous enhancements involving the deployment tool and run time layout of your application that make clear where you're application is loading its files from.
If you've at a long running application server environment, with lots of deployments under your belt, you might start to notice slow downs in deployment and kjs start time. Generally this is due to garbage collecting in your iAS registry.
You can do several things to resolve this. The most complete solution is to reinstall the application server. This will guarantee a clean ldap registry. Of course you've got to restablish your configurations and redeploy your applications. When done, backup your application server install space with the application server and directory server off. You can use this backup to return to a known configuation at some future time.
For the second method: <B>BE CAREFUL - BACKUP FIRST</B>
There is a more exhaustive solution that involves examining your deployed components to determine the active GUIDS. You then search the NameTrans section of the registry searching for Applogic Servlet *, and Bean * entries that represent your previously deployed components but are represented in the set of deployed GUIDs. Record these older GUIDs, remove them from ClassImp and ClassDef. Finally remove the older entries from NameTrans.
Best practices for deployment depend on your particular environmental needs. Many people utilize ANT as a build tool. In later versions of the application server, complete ANT scripts are included that address compiling, assembly and deployment. Ant 1.4 includes iAS specific targets and general J2EE targets. There are iAS specific targets that can be utilized with the 1.3 version. Specialized build targets are not required however to deploy to iAS.
Newer versions of the deployment tool allow you to specify that JSPs are not to be registered automatically. This can be significant if deployment times lag. Registered JSP's however benefit more fully from the services that iAS offers.
2) In general it is better to undeploy then redeploy. However, if you know that you're not changing GUIDs, recreating an existing application with new GUIDs, or removing registered components, you may avoid the undeploy phase.
If you shut down the KJS processes during deployment you can eliminate some addition workload on the LDAP server which really gets pounded during deployment. This is because the KJS processes detect changes and do registry loads to repopulate their caches. This can happen many times during a deployment and does not provide any benefit.
3) Deploying can be a lengthy process. There have been improvements in that performance from service pack to service pack but unfortunately you wont see dramatic drops in deployment times.
One thing you can do to reduce deployment times is to understand the type of deployment. If you have not manipulated your deployment descriptors in any way, then there is no need to deploy. Simply drop your newer bits in to the run time space of the application server. In later service packs this means exploding the package (ear,war, or jar) in to the appropriate subdirectory of the APPS directory.
4) If you've changed the classes of objects that have been placed in HTTPSession, you may find that you can no longer utilize those objects. For that reason, it is suggested that objects placed in session be kept as simple as possible in order to minimize this effect. In general however, is not a good idea to change a web application during the life span of a session.

What is best practice for dealing with Engineering Spare Parts?

Hello All,
I am after some advice regarding the process for handling engineering spare parts in PM. (We run ECC 5)
Our current process is as follows:
All materials are set up as HIBE's
Each material is batch managed
The Batch field is used for the Bin location
We are now looking to role out PM to a site that has in excess of 50,000 spare parts and want to make sure we use best practice for handling the spare parts. We are now considering using a basic WM setup to handle the movement of parts.
Please can you provide me with some feedback on what you feel the best practice is for dealing with these parts?
We are looking to set up a solution that will us to generate pick lists etc and implment a scanning solution to move parts in and out of stores.
Regards
Chris

Hi,
I hope all the 50000 spare parts are maintained as stock items.
1. Based on the usage of those spare parts, try to define safety stock & define MRP as "Reorder Point Planning". By this, you can avoid petty cash purchase.
2. By keeping the spare parts (atleast critical components) in stock, Planned Maintenance as well as unplanned maintenance will not get delayed.
3. By doing GI based on reservation, qty can be tracked against the order & equipment.
As this question is MM & WM related, they can give better clarity on this.
Regards,
Maheswaran.

With Tiger there is a migration assistant that will move everything over from your Powerbook to your new iMac G5. All you need is a firewire cable and when prompted in your first start-up select migration assistant and connect the two computers. You will need to boot up your Powerbook holding down the 't' key before you connect the two together. Good luck, Jack.
