Large 7921 Environment Questions

How do you handle per phone user / password authentication when using EAP-FAST? Do you create 1 credential per user when you distribute the phone or do you have a shared credential for all your phones?

You can do either. But for stronger security, would suggest to have an account per phone. Also this can help when troubleshooting, tracking a phone.

Benefits of RAC in large systems environment

Hi All,
One query regarding RAC
In a large systems environment where multiple CPUs and memory are dynamically available to be deployed for a database server, what are the benefits of a RAC implementation? Obviously no single point of failure is eliminated but how else is performance improved?
Thanks

A clustered system either DB or the system(OS) or any other form of clustering is designed for high availabilty only and not for performance improvement.
Please keep in mind that you need to check the performance of 2 clusterd and non-clusterd systems with the same level hardware and OS resources.
If your application is performing at level 'X' with 4 CPU and 4 GB RAM on a non-clusterd machine then its performance cannot be matched with the 2 machines with 4 CPU each and 4 GB RAM each, because thats the double the resources than available in non-clusterd machince.
Also just keep one more thing in mind that with the same resources now distributed in clustered nodes (ie 2 nodes with 2 CPU and 2 GB RAM v/s 1 node with 4 CPU and 4 GB ram), the single node will alawys perform better because there will be no inter-connect overhead that is there in RAC systems.

German Umlauts OK in Test Environment, Question Marks (??) in production

Hi Sun Forums,
I have a simple Java application that uses JFrame for a window, a JTextArea for console output. While running my application in test mode (that is, run locally within Eclipse development environment) the software properly handles all German Umlauts in the JTextArea (also using Log4J to write the same output to file-- that too is OK). In fact, the application is flawless from this perspective.
However, when I deploy the application to multiple environments, the Umlauts are displayed as ??. Deployment is destined for Mac OS X (10.4/10.5) and Windows-based computers. (XP, Vista) with a requirement of Java 1.5 at the minimum.
On the test computer (Mac OS X 10.5), the test environment is OK, but running the application as a runnable jar, german umlauts become question marks ??. I use Jar Bundler on Mac to produce an application object, and Launch4J to build a Windows executables.
I am setting the default encoding to UTF-8 at the start of my app. Other international characters treated OK after deployment (e, a with accents). It seems to be localized to german umlaut type characters where the app fails.
I have encoded my source files as UTF-8 in Eclipse. I am having a hard time understanding what the root cause is. I suspect it is the default encoding on the computer the software is running on. If this is true, then how do I force the application to honor german umlauts?
Thanks very much,

So you start with a string called "input"; where did that come from? As far as we know, it could already have been corrupted. ByteBuffer inputBuffer = ByteBuffer.wrap( input.getBytes() ); Here you convert the string to to a byte array using the default encoding. You say you've set the default to UTF-8, but how do you know it worked on the customer's machine? When we advise you not to rely on the default encoding, we don't mean you should override that system property, we mean you should always specify the encoding in your code. There's a getBytes() method that lets you do that.
CharBuffer data = utf8charset.decode( inputBuffer ); Now you decode the byte[] that you think is UTF-8, as UTF-8. If getBytes() did in fact encode the string as UTF-8, this is a wash; you just wasted a lot of time and ended up with the exact same string you started with. On the other hand, if getBytes() used something other than UTF-8, you've just created a load of garbage. ByteBuffer outputBuffer = iso88591charset.encode( data );Next you create yet another byte array, this time using the ISO-8859-1 encoding. If the string was valid to begin with, and the previous steps didn't corrupt it, there could be characters in it that can't be encoded in ISO-8859-1. Those characters will be lost.
byte[] outputData = outputBuffer.array();
return new String( outputData ); Finally, you decode the byte[] once more, this time using the default encoding. As with getBytes(), there's a String constructor that lets you specify the encoding, but it doesn't really matter. For the previous steps to have worked, the default had to be UTF-8. That means you have a byte[] that's encoded as ISO-8859-1 and you're decoding it as UTF-8. What's wrong with this picture?
This whole sequence makes no sense anyway; at best, it's a huge waste of clock cycles. It looks like you're trying to change the encoding of the string, which is impossible. No matter what platform it runs on, Java always uses the same encoding for strings. That encoding is UTF-16, but you don't really need to know that. You should only have to deal with character encodings when your app communicates with something outside itself, like a network or a file system.
What's the real problem you're trying to solve?

Large music collection questions...

Hello All,
I am new to iTunes and I have a couple of questions I need answers to before I make a big mess.
I am moving from all windows to all mac environment. My music collection (77,000 songs) exists on several external HDD and are configured for the win 7 machine. The only organization for the collection is my own folder system, it has not been scanned or compiled into a whole by any program, win or mac.
I also have a Mini hard wired to a 2TB TC. I want to get the music into iTunes and I am looking for some direction.
First, I want to clean up the collection and get it all on 1 drive before I move it to iTunes. Or do I? This is my first issue, dont know what to do first. Do I work with the collection in Win first and then move a clean collection into itunes or move it to iTunes first?
I have read about the tuneup program and it seems like it either works great or not. Any opinions here? Of course I am smart enough not to just dump the whole collection on it and expect it to be fluffed and folded in an hour. It is available for Win as well as being an iTunes plug-in... is it better one way or another.
If the opinion is that tuneup is not the best program then what are the better alternatives?
Second question involves final resting place of clean collection. I want to keep the clean collection on an external HDD. Do I want it to be plugged into the mini or the TC for it to be shared accross all devices?
If there is something I am overlooking please chime in, as I said, new to iTunes and Mac and there is a lot to learn.
Thank you for your time in this matter.
Cheers,
Alex

AutoVue for Agile PQM - Java Runtime Environment Question

Greetings,
An end user is attempting to view/open attachments within Agile Product Quality Management (PQM); we use Agile PQM 9.3.1.
When clicking on an attachment file, a pop-up screen opens with a javascript alert, prompting the user with, "Please Install Java Runtime Environment." After clicking "OK", user is redirected to java download website. User downloads and installs the update.
After rebooting the machine, we attempt to access the attachment file again within PQM and receive the same error message, "Please Install Java..."
After installing the first java update, the user is now on the following java version:
Java Plug-in 10.55.2.14
Using JRE version 1.7.0_55-b14 Java HotSpot(TM) Client VM
Do we need to install the second update to be able to view attachments within Agile PQM via AutoVue?
I can't test the java updates myself because there are some legacy Oracle apps that I won't be able to support if I update my java.
Thanks in advance,
William

You might want to post the question to the Agile forum
The popup you see seems to be tied to Agile code itself and not AutoVue
AutoVue will work on Java 7u55
But you are running Agile, so you will need to make sure the rest of the apps are confirmed with 7u55
You also need to review Java update guidelines, by default you will be always prompted to install the latest java update

Configuring our RAC environment Questions

The environment consists of Sun Solaris 10, Veritas, and 10g RAC:
Questions:
I need to know the settings and configuration of the entire software stack that will be the foundation of the oracle RAC environment....Network configurations, settings and requirements for any networks including the rac network between servers
How to set up the solaris 10k structures: what goes into the global zones, the containers, the resource groups, RBAC roles, SMF configuration, schedulers?
Can we use zfs, and if so, what configuration, and what settings?
In addition, these questions I need answers to:
What I am looking for is:
-- special hardware configuration issues, in particular the server rac interconnect. Do we need a hub, switch or crossover cables configured how.
-- Operating System versions and configuration. If it is Solaris 10, then there are more specific requirements: how to handle smf, containers, kernel settings, IPMP, NTP, RBAC, SSH, etc.
-- Disk layout on SAN, including a design for growth several years out: what are the file systems with the most contention, most use, command tag depth issues etc. (can send my questionnaire)
-- Configuration settings\ best practices for Foundation suite for RAC and Volume manager
-- How to test and Tune the Foundation suite settings for thru-put optimization. I can provide stats from the server and the san, but how do we coordinate that with the database.
-- How to test RAC failover -- what items will be monitored for failover that need to be considered from the server perspective.
-- How to test data guard failures and failover -- does system administration have to be prepared to help out at all?
-- How to configure Netbackup --- backups

Answering all these questions accurately and correctly for you implementation might be a bit much for a forum posting.
First I'd recommend accessing the Oracle documentation on otn.oracle.com. This should get you the basics about what is supported for the environment your looking to set up, and go a long way to answering your detailed questions.
Then I'd break this down into smaller sets of specific questions and try and get the RAC axters on the RAC forum to help out.
See: Community Discussion Forums » Grid Computing » Real Application Clusters
Finally Oracle Support via Metalink should be able to fill in any gaps int he documentation.
Good luck on your project,
Tony

Quick Environment Question

It's time I finally delved into the Environment, but I'm a little nervous about messing things up. So here's my question:
If I start Logic and save my Autoload song under either another name or as a project and then start twiddling about in the Environment, will the changes I make in the Environment be reflected the next time I open Logic, or do they only apply to this new saved "song" that I've just created?
Sorry if that's a little naive, but I'm just wanting to be safe.
Thanks!

you'll be alright doing it that way. the environment is particular to a song - not changing any global prefernces or anything.
go twiddle.
check out vector faders. very cool. never used them though. main thing i use in environment is transformers. not cool - just useful.

Please help: large scale Printing question

A Client asked me to do a backdrop for a play that is 10' high by 18' wide. She wont give me the number of where shes getting it printed from for some stupid reason so i cant ask them directly, my question which is this: What size and format should my photoshop file be in for large scale printing like that? Right now my file is 10" high by 18" wide and 300dpi. and its a Psd right now of course. Any help would be awesome.

hu instinct,
Basically, when scaled the artwork has identical appearences at identical proportional distances (looks as if it has the same resolution); in other words: when you look at a 1:1 print of your present 10x18" artwork at a certain distance, the 10x18' backdrop will look the same to the audience/actors/instructor/whoever at 12 times the distance, so if it looks nice to you at 1' or 1.5' or2', it will look just as nice to them at 12' or 15' or 18'.

EJB environment question (static helper classes)

We're using JBoss as AS containing several stateless session beans.
Now, we have certain helper classes that are abstract and contain static methods. Is this a problem for the EJBs? All of them use these helper classes all over their methods. Are they sharing the static class and will slow down somehow? Or is each EJB using its version of the class and can run concurrently?
Should we rethink this and put an INSTANCE of each helper class in each ejb instead of using static methods in the helper class?
Now in EJB method:
Helper.calculateStuff();
Should it be?
Helper h = new Helper(); // defined when ejb is created
helper.calculateStuff();

>
The helper methods do database querries etc and return results that the EJB sends onwards to clients. If these methods
are NOT synchronized (and the ejbs share the static class) won't it cause concurrency errors? I think most of our methods are not
synchronized (and it doesn't seem to cause any concurrency errors so far... though the system have not beeen stressed test that much,
and concurrency bugs tends to pop up later and randomly :P).
>
No, if you dont have any static data variables in the Java classes, static method as such will not cause concurrency errors, and the methods should not be synchronized.
If you have any synchronized methods and they take a while to execute, that could become a bottleneck in itself, because different threads waiting for each other,
so make sure you dont have any synchronized methods where it is not explicitly needed.
Think of a static method (without static data in the class being manipulated) as a plain function in another programming-language.
>
We have some scaleability problems with the EJBs... It seems as if they do not run concurrently. If we do a stress test with several threads calling the EJBs their response time increases by a too large factor to feel comfortable...
>
Apparently, you do have a some scaling/concurrency problem, which could have many causes -- transaction locking and clashes in the database, poorly configured database, network congestion, problems in the EJB architecture, etc -- can be many reasons...
The general idea to debug, is first to find out exactly what calls in your code that take longest time to execute (profiling, logging, System.out.println's are useful) when you put parallel load on your system -- rather than just seeing "the whole application seems slow" -- from there you can move on, "divide&conquer" the problem, etc...

General MII environment questions

Hi,
We are just starting a project to implement MII. We have an MII consultant on site who has stated that in addition to the stock MII install, we need an additional database at each plant for locally caching production orders, purchase orders, inventories (raw, wip, f/g, packaging & ingredients) and other support type data (storage locations, material masters, tolerance, item-pack mapping codes, etc.) in support of the continuous operation requirement.
Are additional databases a common requirement?
If so, is dba level access for developers a requirement? Please keep in mind, they would potentially also want the same access for the production system.
If dba access is not required, couldn't we just add a tablespace (we're using Oracle)?
What is a typical configuration?
The consultant is not familiar with NWDI. His recommendation is to move directories from development environments to production.
Are most MII customers using NWDI including the Change Management Service? If not, how are they controlling and coordinating changes?
It was my impression that some of the data was stored in files and some of the data is stored in the database. Is that incorrect?
Can changes be safely migrated from development to production by copying directories?
Best regards,
Russ

Hi Russ,
I support Mike's comments.
At one time all the MII application "articles" were text based and accessible via Windows Explorer. Now with 12.0+ releases, everything exists in the DB as you are aware. I'm not aware of anyone/customer/partner actually using NWDI with MII. When things were file based, it made it a bit more easy to integrate with some flavor of source control. But, even then, most projects did not use such tools for several reasons (albeit not necessarily good reasons). Many projects are small enough in scope that one person is working on code at a time. So the need for source control to prevent code contamination was not there. It would be helpful for promotions or transports from dev->tst-prd though. But, again, many projects used a possibly archaic method (ie, Excel) to keep track of what files and version of those files were where. At best, when things were file based, source control was used as a nightly backup of files. I could rattle off a number of multi-site, large enterprises that use Excel as their MII SVN tool. Again, it may not be best, but it is a common observation.
Today, yes, MII does work with NWDI. Is it the ultimate in source control/software configuration management? Probably not. Last year in Nashville for the SAP AMS conference, I gave a presentation on Software Configuration Management (SVN being a part of SCM) and MII. I gave some recommendations for incorporating SCM into the MII world. There are different options depending on your version of MII. But, for some combinations of MII and components of SCM, I was not able to provide a solution.
I'm hoping to find a really, really good solution for complete SCM compliance in the MII architecture at some point, but I'm haven't yet.
Regarding local DBs. Yes, if the requirement is limited sustainability or local survivability, then, yes, you will need a DB at each plant (at least one). As far as authorizations for your consultant - well it depends on how much you want them to do on the DB side. If you don't grant permissions, someone who has permissions will need to write the queries and stored procedures, obviously. That's really your call.
Good luck with your MII endeavors.

Eclipse / Workshop dev/production best practice environment question.

I'm trying to setup an ODSI development and production environment. After a bit of trial and error and support from the group here (ok, Mike, thanks again) I've been able to connect to Web Service and Relational database sources and such. My Windows 2003 server has 2 GB of RAM. With Admin domain, Managed Server, and Eclipse running I'm in the 2.4GB range. I'd love to move the Eclipse bit off of the server, develop dataspaces there, and publish them to the remote server. When I add the Remote Server in Eclipse and try to add a new data service I get "Dataspace projects cannot be deployed to a remote domain" error message.
So, is the best practice to run everything locally (admin server, Eclipse/Workshop). Get everything working and then configure the same JDBC (or whatever) connections on the production server and deploy the locally created dataspace to the production box using the Eclipse that's installed on the server? I've read some posts/articles about a scripting capability that can perhaps do the configuration and deployment but I'm really in the baby steps mode and probably need the UI for now.
Thanks in advance for the advice.

you'll want 4GB.

Environment question for experts...

Is it possible to save an environment layer, for example a multichannel VI setup, to then import into another song?
Thanks...

You can't save an individual Environment layer (as "in a discreet Environment file"), but as the previous poster said, you can copy and paste Environment elements between two open songs (make sure "hide inactive songs" is unchecked in your prefs).
Note, however, that you can't copy/paste the layer itself; you can only copy/paste the objects in a layer between songs. If you want to create a similarly named layer in your target song, use the Create New Layer function in the Environment and then re-name it. Note also that you can't change the order in which the layers are listed in the Environment. So if you create a new layer, it will always appear as the bottom-most layer in the layer list. You can't move it inbetween existing layers or move it to the top.
On the flip side, you can import whole, individual layers from one song into another using the import functions available within the Environment (and the song from which the layer is imported does not have to be open). But depending on what you're trying to do you may end up with huge headaches. The import functions are not only a bit hard to understand, but they're buggy in some respects.
So post what you're trying to do exactly and I'm sure people will chime in as to whether you're better off copying/pasting or using the import layer function.

Environment Question. How to send to external midi devices

Hi All,
I used to be able to do this but now can't remember. Basically, I'd like to control an external synth from logic..... Edit an instrument performance then run it to say a moog and record the audio back in. What do I need to do in the environment to make this happen?
Thanks!!

Old way:-
Open the environment, create a New -> Instrument. Name it "Moog" (or whatever), and chose the MIDI port and channel it responds on.
Back in the arrange, control-click on a track, select "Reassign track object" and choose the "Moog" instrument to assign it to a track. Now all notes on this track get sent to the Moog.
Audio you record in the normal manner.
Newer way:
On a software instrument, add an "External Instrument" plugin. Choose the MIDI port and channel (or your "Moog" instrument) and the audio inputs the audio is coming back on. Now you can treat your hardware synth in a similar way to regular software instruments.

Environment question

Hey everyone,
I am fiddling around in the environment trying to learn a little bit more. I am not sure how, but I have stopped all sound from coming out of Logic (MIDI, audio, and all). I was playing mainly with MIDI in/out stuff and all of the sudden nothing is making any noise. It seems to be an environment issue because there is nothing registering in the audio track meters.
I have been digging around for about 20 minutes trying to find the issue, but to no avail. Does anyone have any suggestions?

ronketti,
There's a chance that the cabling you mentioned didn't disappear by your doing. There was a problem in Logic 7 where this cable would disappear all by itself. Strange but true. It happened to me several times, and there were numerous subsequent posts about it from other people on various forums. And it usually happened to people who weren't even close to messing around in the Environment. I guess I'm hoping out loud that this problem doesn't still exist in L8.

MUD Environment question.

Hi,
As of now, I have a development and a live environment for OBI. All OBI EE services run on individual servers (virtual). Can I setup MUD in this scenario? My assumption was development would be used to develop projects. A test environment for Merging the projects. When the merged repository is tested by the QA team, then I shall release the tested rpd to the Live environment. Is this correct? If not, could you please let me know how I could setup the MUD with the given environments?
Thanks,
Manoj.

To set up MUDE there is no need to change the Insatnceconfig file.
what happens to the samplesales.rpd in the default location and to the master repository in the shared location "H:\OBI_Shared_Folder\"?
Lets say you need to add one new presentation catalog in the rpd?
With no mude ---> You need to modify rpd either in online or offline and samplesales.rpd should be modified.
With MUDE -->- You need to open the administrator - File - Multiuser - Check out. Now if you see the rpd name you are modifying the version of Shared_samplesales.rpd not the original rpd.
With mude once you are done with the modification you need to move Shared_Samplesales.rpd from H:\ drive to the actual Server-> Repository and you need to rename the Shared_Samplesales.rpd to samplesales.rpd which is there in the instanceconfig file.
Means, no need to change the instanceconfig file.
For QA Team testing ---- You need to refer to the SHARED_Samplesales.rpd which is latest. Move it to Server--->Repository -> Rename - Bounce servers and test it.
Since you do not have separate environment once Migration of file from shared to folder to actual folder testing should be.
