OutOfMemoryError - good way to handle this error?

Hello.
I am pulling in images into an array, and every now and then I will get an error stating:
OutOfMemoryError
I posted earlier concerning how to examine whether an image can be garbage collected or not, and I got some useful replies.
But, I was wondering if there were any tips on how to handle this error.

In general you cannot handle this error as it is possible that your
error handling code with cause the error again. In reality you
can catch it somewhere where you know a large chunk of memory has been
freed.

What's a good way to handle this conversion to a QUAN field?

Good day everyone,
I developed an RFC that receives data from XI. I assign this data to a BAPI, and one of the fields is a field with a data type of QUAN(length 13, decimals 3). All works fine if XI passes me a numeric value in this field.
Here's the problem: In running some test cases through XI and into the RFC, we ran a test case where the quantity field had a value of "test" (e.g. no numeric value). Incredibly, XI transforms the text value of "test" into the value of 4534 and sends it to my RFC. So my RFC thinks everything's fine when, in fact, that number was derived from a text field and is completely wrong.
What we need to do is change the field to something that will "kick out" in XI when it tries to call my RFC. I thought I could change it to a type of NUMC, but that doesn't let me use decimals. We've already sent out the file layout to vendors, so we expect them to include numeric values with decimal places if need be.
Is my best bet changing this to a character field with a length of 17, then checking to make sure it consists only of 0-9, a space, or a decimal? I then need to assign it to the BAPI's field with the data type of QUAN(13,3) -- am I going to have issues trying to do this from a character field? Do I need to worry whether or not they include a decimal (it might be implied -- in other words, they might just say quantity is "20" which becomes "20.000" to the BAPI). Is there a nifty routine I can use to do all this easily?
Thanks everyone. Points awarded as always for ALL helpful answers.

Ravi, that's kinda what I was thinking, but if it's true (i.e. a proper amount) can I just move the contents directly to my QUAN field? Will SAP automatically do the conversion for me such that it ends up in the right place? I've yet to have to worry about such conversions -- this is the first time I've had to deal with it -- and I want to make sure that the right value gets assigned, whether that value is "20", "54.1", "1000.25", or "986.500".

What's the best way to handle this?

I'm not sure what APIs/setup to use for this situation:
A company wants to store data projects they do for clients. Each year, the data fields are set (as a result of gov't requirements) and they won't change for any client project for that year. however, the fields required can (and usually do) change every year. So things they require this year, might not be needed the next year and new fields might be introduced.
While there are likely to be many common fields from year to year, there's no way to guarantee which ones will remain consistent. They also want to be able to do searches on the data and fields, for projects within a year and across years.
What's the best framework/API/configuration to handle this? EJB? Simple JDBC? If so, how should the database be handled? Won't it have to constantly create new fields in a table? Or is there another way to handle this?
What's the best way from a "clean architecture" standpoint?

dang, I really have to start over? I finally got all this stuff working again. well, hopefully it won't be as big a pain this time since the data won't be coming from a different machine. After completing the Migration Assistant process, I had to reinput a bunch of serial numbers for apps, reinstall print and mouse drivers, etc... I've finally got the new machine up and running smoothly and now I gotta start over? Sigh.
I was hoping that either I could rename the current account after deleting the other one, or just move everything from one account to the other and then delete the 'RJM' account.
ok, so it sounds like here are the steps I need to take:
- make another full cloned backup of this current machine in Super Duper
- reboot this machine using the advice in the first post, wipe everything clean and reinstall the OS
- create a new account like 'user1' and re-do software update (which is like 2.5 gig worth of stuff) and takes like an hour even on a high speed connection
- then re-do the migration assistant process to the properly named account
- then delete the 'user1' account
does that sound right?

Is it good way of using this?

Hi Experts,
                 Is it using inside loop , select single -
statement, is it good way of using this during performance? Pls suggest me

//Is it using inside loop , select single -
statement, is it good way of using this during performance? Pls suggest me
See
loop at itab.
       select single ...
       endloop.
This is as good as executing the select statement the number of times as the entries in table itab.
You can use this but when it comes to performance then say suppose 10000 entries are there then select is executed 10000 times .
If u do a Sql trace ST05 on the code it will show u in minute(s) .
So if i do a select and read all the entries into an internal table and now compare this with the Read statement then the performance will be high .

What's a good way to do this?

I'm an old C programmer learning Java. As an exercise, I'm writing a
fairly simple astronomy program, and one of the things it needs to do is
to convert between two different coordinate systems, (altitude, azimuth)
and (hour angle, declination).
As it happens, it's possible to write a single conversion function that
works in both directions. In C, the prototype might look like
void convert( double latitude, double fromX, double fromY,
double toX, double toY );
and I could call this two different ways.
convert( lat, alt, az, &ha, &dec );
convert( lat, hr, dec, &alt, &az );
Is there an elegant way to implement this in Java? Everything I can
think of feels kinda kludgy and slow (convert() can easily be called
millions of times).
I know I could represent the coordinate pairs as double[] and have
public static void convert( double lat, double[] from, double[] to )
but I'm not real happy with that. I'd have to use double[] in the rest
of the program, which would mean things like
star[ i ].EqCoord[ 0 ]
star[ i ].AACoord[ 1 ]
instead of the more concise and self-documenting
star[ i ].ha
star[ i ].az
Or I could wrap the calls to convert() with something like
double[] result = new double[ 2 ];
convert( lat, star[ i ].alt, star[ i ].az, result );
star[ i ].ha = result[ 0 ];
star[ i ].dec = result[ 1 ];

Thanks kglad! I think I'm getting the logic looking at a
number of examples.
Would I head in this direction?
onClipEvent (load) {
moveTo(ball_mc._x,ball_mc._y);
_root.onEnterFrame = function(){
lineTo(ball_mc._x, ball_mc._y);
lineStyle(3, 0xee3355, 100);
Or this direction:
onClipEvent (load) {
/* x & y co-ordinate for the movieclip code.*/
x1 = _parent.ball_mc._x;
y1 = _parent.ball_mc._y;
moveTo(x1,y1);
lineStyle(3, 0xee3355, 100);
onClipEvent (enterFrame) {
lineTo(_parent.code._x, _parent.code._y);

Best way to handle this producer-consumer situation

This is, i'm sure a common thing, however, I never really thought about it before. I can't post my VI so a description will have to do. It should go without saying, but I will repeat it's producer-consumer architecture. Let's say you have a signal generator and all the controls for it are in a cluster. A value changes, fires an event in the producer loop and you compare new and old values to determine which button changed. Cool, all good. So then I queue up a read front panel state in my prodcuer loop which is dequeued in my consumer loop. The read front panel state loads all the new values into a cluster which then is fed into a shift register to be accessed from anywhere in my code (see here).
Now my question is, what should my next state be that I queue up? If I have a single "send commands to sig gen" state, in my consumer loop I again have to determine which value changed in order to know which command to send (because the original determination of what changed was in the producer loop). However, if I have an individual state for each command I want to send, my case structure will get very big, very fast.
Final option is have one send command state and just write all data on a single control's value change, whether it's new or not (this seems overkill).
Suggestions please?

For situations like this I would not send a "state" to the consumer. I send a "command." When the consumer receives a command, it determines whether that command is executed immediately or whether it completes the task in process and then handles the new command.
Along with the command I send a parameter or parameters. For your signal generator the parameters would probably be something like a cluster of "control ID" and "value." The control ID would probably be a typedefed enum and the value a DBL.
What ever you decide, think about it, plan it, and document it before you code it.

Collecting Caller Inputs - best way to handle this?

Greetings,
My apologies in advance, I'm sure this has been asked before and I did try the search function.
So we have a need to collect, and report on, caller inputs on a couple of menus. For example - one menu offers three options, and based on your choice you could go to another menu with five options, etc. And we're trying to get a handle on the best way to collect and report on callers inputs at the various levels. We know UCCX comes with ten custom variables however, if we have custom variables doing other things can we reuse them? Or, once they are designated to do something are they no longer available?
Would it be best to use a log file of some kind/type?
If there are posts (somewhere) discussing this, a link would be spectacular.
For those of you who have dealt with this your insights would be appreciated.
Thanks for your time and attention!

DOWNLOADED THE LATES ITUNES BUT NOW I CAN NOT FIND THE BACKUP OPTION IN THE LIBRARY. BACK UP TO DVD, SO HOW IS THE BEST WAY TO HANDLE THIS?

I DOWNLOADED THE LATEST UPDATE TO ITUNES AND NOW CAN NOT FIND HOW TO BACKUP MY LIBRARY

The backup to disk option was removed as of iTunes 10.4. If you want to back up your tracks to a CD, you can as a workaround put the tracks in a playlist and then use the Burn Playlist to Disk command and select a data disk as the format. If you want to back up your tracks to a DVD now, you'll need to use other software. Unless your library is pretty small, though, it's probably a lot more effective to just copy the entire iTunes folder to an external hard drive or USB flash drive.

How to handle runtime error in PreUUT step when running in Parallel mode

I would like to run Test UUTS in parallel mode, and some actions are done in PreUUT such like read serial number and fixture control.
The process model won't goto PostUUT Step when runtime error occurs in PreUUT step, so i would like to add some actions to check if sequence error in cleanup and go back to setup in PreUUT step, but i find it skip all the actions in setup and main step?
What should i do if i want to go back to run PreUUT again as the first time to run when runtime error occurs?
Or, is there any good way to handle this kind of error withour restart program?
Solved!
Go to Solution.

This question does not depend on PreUUT or ParallelModel at all.
First of all:
A Runtime Error is a situation where TestStand encounters a problem which makes further testing either impossible or senseless. So a Runtime Error always indicates a situation where proceeding the test sequence is not recommended.
Nevertheless, there are situation where you want to handle those errors without stopping the execution. A "traditional example" for this is initialising serial/GPIB devices. If the device does not reply, there might be different issues the operator can easily resolve and (if corrected) the sequence can proceed properly. The operators action could be:
- Check if device is switched on
- Check connection between PC and device
So the error state is used to inform the operator about the malfunctioning device and regarding of the actions the operator takes, the execution will either proceed or terminate.
When TestStand encounters a Runtime Error, it initially reacts with displaying a dialog. This behavior can be modified in the Station Options >> Preferences >> On Runtime Error.
Furthermore, you can install callback sequences which are called if an error occurs. Those would be either SequenceFilePostStepRuntimeError or ProcessModelPostStepRuntimeError (depending on the fact if you are changing the process model or simply working with client sequence file callback overrides). These are "normal" sequences you can use in order to get system information, loop on the step or....essentially do whatever you want. If you want to proceed though, you must not forget to reset the error flag.
hope this helps,

Whats a good way switch between a real and mock data service?

I have a new Flex application...and am contemplating the use of the Mate mock remote object capability.
However, I'd like the application to be able to switch back and forth between a real and mock data service without recompilation. And without loading the mock service objects unless they are needed.
Whats a good way to handle this switching without recompiling the application?

The only way I can think of not having ANY mock services in the production code is to take them out manually. Your program for mocking purposes is going to have to be able to know where these services/object are and how to contact them. I'm sure if it had to be done , you could use some mass of modules and event maps.
Sincerely ,

Is this a good way for loading and handling an xml file?

I'm new to xml files, but it seems to me that a good way to handle them may be this:
- create an xmltype table with a unique xmltype column
- load the xml file in the xmltype column of the table
- writing a procedure for scanning the whole column of the table by using the extractvalue built-in function for inserting the different nodes of the xml file (just loaded) in the final tables (to link correctly the father and son tags with foreign keys)
Does it seem to you a good way to load the nodes of a xml file in a relation database?
Thanks!

Is this the 10gR2 Express Edition you mentioned over in How to load a XML file into a table or a different version?
