Best Practice for Handling Timeout

Hi all,
What is the best practice for handling timeout in a web container?
By the way, we have been using weblogic 10.3
thanks

Are you asking about this specific to web services, or just the JEE container in general for a web application?
If a web application, Frank Nimphius recently blogged a JEE filter example that you could use too:

Ignore the tailor fitted ADF options, this should work for any app.

Best practices for handling elements and symbols (including preloading)

I am trying to learn Edge Animate and I have not seen enough animations to know how this is typically handled and I searched the forum and have not found an answer either.
If you have many different elements and symbols for a project, what is the best practice for having them appear, disappear, etc. on the timeline? I ask this question not only from a performance based perspective, but also keeping in mind the idea of preloading. This is a 2 part question:
Part 1: Using elements and symbols later in the timeline:
Since artwork is always imported directly to the stage in an "always on" status, should we place a visibility OFF on every item until we need it?
or should they be opacity 0 until I need them?
or should they be set to visibility hidden until I need them?
Which of these is the best option if you don't want the element / symbol visible until later in the timeline? Does it matter?
Part 2: Impact on page loading
Does the above question have any impact upon page loading speed
or is this something handled in preloading?
or do you need to make a special preloader?
Thanks for the help.

Hi, escargo-
Good questions!
Part 1: Using elements and symbols later in the timeline:
Since artwork is always imported directly to the stage in an "always on" status, should we place a visibility OFF on every item until we need it?
or should they be opacity 0 until I need them?
or should they be set to visibility hidden until I need them?
Which of these is the best option if you don't want the element / symbol visible until later in the timeline? Does it matter?
I would recommend that you set your visibility to "off" instead of simply changing the opacity. The reason I suggest this is that when your visibility is set to off, your object's hit points also disappear. If you have any type of interactivity, having the object still visible but with 0 opacity will interfere with anything you have underneath it in the display order.
Part 2: Impact on page loading
Does the above question have any impact upon page loading speed
or is this something handled in preloading?
or do you need to make a special preloader?
Thanks for the help.
No, none of this has any impact on page load. As you already noticed, all of the assets of your project will load before it displays. If you want only part of your composition to load, you may want to do what we call a multi-composition project. There's a sample of that in the Edge Animate API in the Advanced section, and plenty of posts in the forums (and one in the team's blog) explaining how to do that.

Best practice for handling errors in EOIO processing on AEX?

Hi,
I'm looing for resources and information describing the best practice on how to handle processing errors of asynchronous integrations with Exactly-Once-In-Order QoS on an AEX (7.31) Java only installation. Most information I've found so far are describing a the monitoring and restart jobs on AS ABAP.
Situation to solve:
multiple different SOAP messages are integrated using one queue with an RFC receiver. On error the message status is set to Holding and all following messages are Waiting. Currently I need to manually watch over the processing, delete the message with status holding and restart the waiting ones.
Seems like I can setup component based message alerting to trigger an email or whatever alert. I still need to decide on how to handle the error and resolve it (ie. delete the errornous message, correct the data at sender and trigger another update). I still need to manually find the oldest entry with status waiting and restart it. I've found a restart job in Background jobs in configuration and monitoring home, but it can be only scheduled in intervals of 1 or more hours.
Is there something better?
Thank you.
Best regards,
Nikolaus

Hi Nikolaus -
AFAIK - For EOIO, you have to cancel the failed message and then process the next message in the sequence manually..
Restart job only works the messages which are in error state but not in holding state.. So you have to manually push the message... So there is no other alternative.
But it should not be that difficult to identify the messages in a sequence..

Though it is for older version, it should be the same.. you should be able to select the additional columns such as sequence ID from the settings..

Can you provide a test case that shows the structure of the data and how you've generated the index? Otherwise, the generic advice is going to be "use prefix indexing".

Best practice for handling data for a large number of indicators

I'm looking for suggestions or recommendations for how to best handle a UI with a "large" number of indicators. By large I mean enough to make the block diagram quite large and ugly after the data processing for each indicator is added. The data must be "unpacked" and then decoded, e.g., booleans, offset binary bit fields, etc. The indicators are updated once/sec. I am leanding towards a method that worked well for me previously, that is, binding network shared variables to each indicator, then using several sub-vis to process the particular piece of data and write to the appropriate variables.
I was curious what others have done in similar circumstances.

I can certainly feel your pain.
Note that's really what is going on in that png You can see the Action Engine responsible for updating the display to the far right.
In my own defence: the FP concept was presented to the client's customer before they had a person familliar with LabVIEW identified. So I worked it this way from no choice of mine. I knew it would get ugly before I walked in the door and chose to meet the challenge head on anyway. Defer Panel Updates was my very good friend. The sensors these objects represent were constrained to pass info via a single ZigBee network so I had the benefit of fairly low data rates as well but even changing view (Yes there is a display mode that swaps what information is displayed for each sensor) was updated fast enough that the user still got a responsive GUI.
(the GUI did scale poorly though! That is a lot of wires! I was greateful to Jack for the Idea to make align and distribute work on wires)

Best practices for handling large messages in JCAPS 5.1.3?

Hi all,
We have ran into problems while processing larges messages in JCAPS 5.1.3. Or, they are not that large really. Only 10-20 MB.
Our setup looks like this:
We retrieve flat file messages with from an FTP server. They are put onto a JMS queue and are then converted to and from different XML formats in several steps using a couple of jcds with JMS queues between them.
It seems that we can handle one message at a time but as soon as we get two of these messages simultaneously the logicalhost freezes and crashes in one of the conversion steps without any error message reported in the logicalhost log. We can't relate the crashes to a specific jcd and it seems that the memory consumption increases A LOT for the logicalhost-process while handling the messages. After restart of the server the message that are in the queues are usually converted ok. Sometimes we have however seen that some message seems to disappear. Scary stuff!
I have heard of two possible solutions to handle large messages in JCAPS so far; Splitting them into smaller chunks or streaming them. These solutions are however not an option in our setup.
We have manipulated the JVM memory settings without any improvements and we have discussed the issue with Sun's support but they have not been able to help us yet.
My questions:
* Any ideas how to handle large messages most efficiently?
* Any ideas why the crashes occur without error messages in the logs or nothing?
* Any ideas why messages sometimes disappear?
* Any other suggestions?
Thanks
/Alex

* Any ideas how to handle large messages most efficiently? --
Strictly If you want to send entire file content in JMS message then i don't have answer for this question.
Generally we use following process
After reading the file from FTP location, we just archive in local directory and send a JMS message to queue
which contains file name and file location. Most of places we never send file content in JMS message.
* Any ideas why the crashes occur without error messages in the logs or nothing?
Whenever JMSIQ manager memory size is more lgocialhosts stop processing. I will not say it is down. They
stop processing or processing might take lot of time
* Any ideas why messages sometimes disappear?
Unless persistent is enabled i believe there are high chances of loosing a message when logicalhosts
goes down. This is not the case always but we have faced similar issue when IQ manager was flooded with lot
of messages.
* Any other suggestions
If file size is more then better to stream the file to local directory from FTP location and send only the file
location in JMS message.
Hope it would help.

Best practice for handling original files once movie is complete?

So I'm taking movies from my Canon S5IS (and other cameras in the past) and making projects in iMovie, sharing in the Media Browser, importing into iDVD, and burning to DVD.
I can't help but wonder if I might need the original footage one day. Do most people keep their original files for future media (replacement for DVD) which I realize would require recreation of the movies that were created in 2008 with iMovie (with title screens, transitions, etc.)? Or do most people delete the originals with the feeling that DVD will be a suitable way to watch home movies for the foreseeable future?
I just can't figure out what to do. I don't want to burn dozens of DVDs of raw footage, only to have keep up with them in a safe deposit box and have to deal with the anxiety of having to recreate movies one day (which is daunting enough now...unbelievably daunting to think about the exponential growth as time progresses).
Hope this make sense. Reading that DVD movies are not suitable for editing due to the codec has made me realize I need to think through this before destroying all these originals as I'm finished with them.
Thanks in advance!
-John

If any of your cams are miniDV, then you simply need to keep the original tapes and tape is still the safest long term archiving solution, when stored properly.
Other cams that use flash memory, hard drives, even DVD cams, do not offer the security that tape does. If you are wanting to save those types of files, the best option would be to store them on one or two external hard drives, bearing in mind those drives could fail anytime. Back up to your back up in that case.
Another nice thing about miniDV cams is that you can export your finished movie back to a tape also, using iMovie HD6, and have safe copies of original and finished material.

Best practice for handling local external assets in Air?

When setting up a project (as3 mobile not flex framework ideally), where and how might one place their runtime-loaded application assets?
Especially, does anyone have example code for referencing local files such that it works across android, iOS and the local debugger/local playback?
Thanks,

Just have a folder to collect your assets and call with an relative path. Because you'r going to attach the files and folder while packaging which is refered by your app.

Best practice for handling custom apps tracks with regards to EP upgrade?

Hi,
We've are currently in the progress of upgrading from EP 6 to EP 7.0, and in that context we need to "move" our tracks containg development of custom J2EE components.
What we've done so far is :
1.Create a new version 7.00 of each software component we have developed with correct EP 7 dependencies
2. Create a new version 7.00 of our product in the SLD: Bouvet_EP
3. Attached the new versions of the SCs to the new product version
4. Create a new track with the SC of version 7.00 along with relevant dependencies
My question now is how do we get the EP 6 component source code into the new track, so that we can change dependecies of the DCs and build it again for EP 7.0?
Should we somehow export the code from the old track, check in and transport ? (how do we then export the code from the track)
Regards
Dagfinn

Hi Dagfinn,
This is a really interesting thread. I have not encountered this scenario till now. However i can only guess.
1. Copy the latest sca files generated for all the SC's in your track from one of the subdirectories of JTrans and place those sca files in the inbox directory of target CMS. Check if these sca are available in the Check-in tab. I think this will not work because the SC verion you have defined in SLD for WAS 7.0 is different than the one in SLD for WAS 6.40.
2. Second and crude method may be you create a SC in the source SLD similar to ones created in target SLD. Create a track for these SC's in the source system. Then create a track connection between the newly created track and existing tracks. Forward all the sources to the target track. Then assemble this SC and copy the sca file and repeat the process above.
I dont know. Possibly this may click. Notes 877029 & 790922 also give some hints on migration of JDI server.
Please do keep this thread updated with your progress.

Sidharth

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.

Maheswaran.

Best Practice for disparately sized data

2 questions in about 20 minutes!
We have a cache, which holds approx 80K objects, which expired after 24 hours. It's a rolling population, so the number of objects is fairly static. We're over a 64 node cluster, high units set, giving ample space. But.....the data has a wide size range, from a few bytes, to 30Mb, and everywhere in between. This causes some very hot nodes.
Is there a best practice for handling a wide range of object size in a single cache, or can we do anything on input to spread the load more evenly?
Or does none of this make any sense at all?
Cheers
A

AHi A,
It depends... if there is a relationship between keys and sizes, e.g. if this or that part of the key means that the size of the value will be big, then you can implement a key partitioning strategy possibly together with keyassociation on the key in a way that it will evenly spread the large entries across the partitions (and have enough partitions).
Unfortunately you would likely not get a totally even distribution across nodes because of having fairly small amount of entries compared to the square of the number of nodes (btw, which version of Coherence are you using?)...
Best regards,
Robert

Best practice for passing parameters to a Timer event handler?

The code hinting is suggesting that I use a Timer object rather than setTimeout or setInterval, however I need to pass a parameter to the timer handler.
What is the best practice for doing this?
+ Subclass Timer?
+ Subclass TimerEvent?
+ Global variable?
+ other?
Thanks

Hmm. I don’t think I would’ve chosen that option. I would probably create a class that listens for the TimerEvent dispatches a custom event. Unless there is information you need in TimerEvent, I don’t see a need to extend it.

Best practice for keeping a mail session open in web application?

Hello,
We have a webmail like application where users login with their IMAP credentials, then are taken to an authenticated area of the site where they can manage different things about their email account.
Right now the application is opening and closing a mail store connection (via a new javax.mail.Session) for each page load based on the current logged in user credentials. To me this seems like it would be a bad practice to keep opening and closing a connection each page load.
Are there any best practices for this situation? It would be nice to be able to open the connection to the mail server on login, then keep that connection open until the person logs out, session expires, etc.
I can probably put the javax.mail.Session into the HTTP session, but that seems like it would break any clustering functionality of tomcat. This would be fine if the machine the user is on didn't fail, but id assume if they failed over to another the mail session would be gone. Maybe keeping the mail session in the http session, checking for a connection, then first attempting to reconnect with the logged in credentials before giving up would be a possiblity?
Any pointers would be appreciated

If you keep the connection open across pages, you're going to need to deal with
timeouts - from the http session and from the mail server.
If you don't keep the connection open, you're going to need to "resynchronize"
your view of the store/folder with each operation, in case the folder is modified
by another session.
The former is easier in the common cases, especially if you don't care how gracefully
you handle failures. The latter is more difficult in the common cases, but handles
failure better, and in particular handles clustering better. You'll need to measure it to
see if it meets your performance and scalability requirements. You may need to mix
the two approaches to get acceptable performance.
