Ps -ef -o args

Hi Guys!
I'm working on some perl scripts which need to check some config files from running processes. My problem is that the with of the args column of the ps command sometimes is too small to display the full path of the config file.
Till now I haven't found a solution to enlarge the column.
Has anybody got some suggestions?

/usr/bin/ps displays the kernel buffer that holds a portion of the initial execution string. That buffer is limited to 80 characters.
You can display the process's buffer (ARGV[0]) via 'pargs' if you have sufficient privileges (or via /usr/ucb/ps on older systems), but be aware that the process can change that buffer as it runs.

Performance problem: Query explain plan changes in pl/sql vs. literal args

I have a complex query with 5+ table joins on large (million+ row) tables. In it's most simplified form, it's essentially
select * from largeTable large
join anotherLargeTable anothr on (anothr.id_2 = large.pk_id)
join...(other aux tables)
where large.pk_id between 123 and 456;
Its performance was excellent with literal arguments (1 sec per execution).
But, when I used pl/sql bind argument variables instead of 123 and 456 as literals, the explain plan changes drastically, and runs 10+ minutes.
Ex:
CREATE PROCEDURE runQuery(param1 INTEGER, param2 INTEGER){
CURSOR LT_CURSOR IS
select * from largeTable large
join anotherLargeTable anothr on (anothr.id_2 = large.pk_id)
join...(other aux tables)
where large.pk_id between param1 AND param2;
BEGIN
FOR aRecord IN LT_CURSOR
LOOP
(print timestamp...)
END LOOP;
END runQuery;
Rewriting the query 5 different ways was unfruitful. DB hints were also unfruitful in this particular case. LargeTable.pk_id was an indexed field as were all other join fields.
Solution:
Lacking other options, I wrote a literal query that concatenated the variable args. Open a cursor for the literal query.
Upside: It changed the explain plan to the only really fast option and performed at 1 second instead of 10mins.
Downside: Query not cached for future use. Perfectly fine for this query's purpose.
Other suggestions are welcome.

Other suggestions are welcome.Best wild guess based on what you've posted is a bind variable mismatch (your column is declared as a NUMBER data type and your bind variable is declared as a VARCHAR for example). Unless you have histograms on the columns in question ... which, if you're using bind variables is usually a really bad idea.
A basic illustration of my guess

NI 845x USB: Error -301713 occurred at Property Node (arg 2) in General I2C Read.vi

Hello,
I am currently working with digital accelerometer LIS35DE from ST Microelectronics. I want to start with tests of this device. For that purpose I used NI 845x USB to connect with accelerometer via I2C. Unfortunately, when I made electrical connections and set up parameters of communication and run the program (I found it in examples) the following error occured:
Error -301713 occurred at Property Node (arg 2) in General I2C Read.vi
Possible reason(s):
NI-845x: An input parameter, or combination of parameters, is invalid. An example of this error may be setting an invalid baud rate or enabling I2C ACK polling while using 10-bit addressing.
The code can be found in attachements. I couldn't find any extended description of this problem. What could be a problem: incorrect device address, register address, configuration parameters?
Any help is appreciated!
Best regards,
Michael

General I2C Read.vi ‏24 KB

Hi MicMac89!
First of all could you please post which version of LabView are you using?
Could you please tell me which version of 845X hw are you using? (8451 or 8452)
I opened the example you attached. As you wrote the error occurs at the second argument of the property node. (I guess this is the first property node where the error occurs.)
This argument of the property node enables the onboard pull-up resistors. But not all NI-845x hardware support pull-up resistors. (Because of this is important to know which hw version are you using.)
Did you try the example with disabling the pull-up resistors?
I suggest you to go through the Manual of this product, (if you did this not yet) This could make it clear where and when to use what kind of pull-up resistors.
For example: If you are using 8452, you must enable pull-up resistors, for Vref ≤ 1.8 V for the FPGA to properly detect a low-to-high transition
Manual: http://www.ni.com/pdf/manuals/371746d.pdf
HW specification: http://www.ni.com/pdf/manuals/290598a.pdf
Please post if my suggestions helped. Of course if you have any questions, don't hesitate to post them.
Best regards,
Balazs Nagy

Error 1073807202 occurred at Property Node (arg 1) in VISA Configure

I am working with the 30-day evaluation version of LabVIEW
(Version 9.0 32-bit). I am attempting to perform the serial loopback test
described in NI's Developer Zone Tutorial, executing Basic Serial Read and
Write.vi. When I click the Run arrow a dialog box appears with the
following legend:
"Error 1073807202 occurred at Property Node (arg 1) in VISA Configure
Serial Port (Instr).vi>Basic Serial Read and Write.vi. LabVIEW: VISA or
code library could not be located. ...required drive not installed..."
I can find the "smplserl.vi" driver in the /examples folder on my PC.
What's wrong?

Did you do a search for that error? Install NI-VISA.

How to call java with public static void main(String[] args) throws by jsp?

how do i call this from jsp? <%spServicelnd temp = new spServicelnd();%> does not work because the program has a main. can i make another 2nd.java to call this spServiceInd.java then call 2nd.java by jsp? if yes, how??? The code is found below...

In general, classes with main method should be called from command prompt (that's the reason for main method). Remove the main method, put the class in a package and import the apckage in your jsp (java classes should not be in the location as jsps).
When you import the package in jsp, then you can instantiate the class and use any of it's methods or call the statis methods directly:
<%
spServiceInd spsi = new spServiceInd();
spsi.SubmitMsg();

Potential Args, Computer shutting down while playing a game

I've only had this mac for 5 months, but it keeps shutting down while I'm playing StarCraft II. It should be able to handle the game, but it keeps telling me to restart and I have no idea what the error says or means. I'm not sure what (4 potential args on stack) means. I'm not sure if it is a frame rate issue and how to fix it or change the frame rate if needed. Any help would be much appreciated. The error is below:

You are only just beginning to feel the pain of Starcraft II on your Mac. Have you seen this List of problems?
Blizzard created the junk, and it's up to them to properly patch it. The list of other well known and respected programs it's incompatible with (LittleSnitch, AppCleaner, FileVault, and PeerGuardian to name a few) doesn't give me a warm and fuzzy.
The page also mentions that your CPU can overheat, for whatever reason, and that means total failure for a laptop or early component damage to a motherboard. Gee, that sounds like something that shouldn't be run on a regular basis.

It looks like my MBP optical drive is dead - arg!

I have a Macbook Pro - circa 2006. This one does not have apple care.
I've got a blank cdr stuck inside it. As near as I can tell the macbook
does not even know it has a cd/dvd drive anymore. The drive is spinning,
but the OS does not see a disk. Nothing in disk utility. Holding down
mouse button or eject key does nothing. Trying drutil seems to do nothing.
Choosing about this mac tells me there no Disc Burning device was found.
Arg.
I don't burn things on this machine often, so it is not critical, but is nice to have. The geniuses I run into seem to know less than the people here. I guess I should give them a try, but I'm already afraid of what they'll estimate for repair.
I'm thinking just buy an external cd/dvd drive/burner would be a good option for this machine. Any specific suggestions? Anything more I should try before I throw money at it?
The other issue is, I hate wasting battery spinning a disk the machine cannot seem to see. Do I have to open the machine up (or pay somebody to do it) to turn
off the defective internal drive?
Is there a reasonably priced internal (or external) drive that would be recognised by the system should I have to reload or update the OS at some point?
Thanks for your help.

It may be something of a long shot, but you might check to see that DVD player is still in your applications folder. Also, you could try verifying both permissions and the disk, and repair if necessary. I don't know if that will help, but it won't hurt anything. It may even be worth trying to reinstall the OS, just in case it has somehow gotten corrupted and is not recognizing the optical drive. It might be worth booting from your install disc and navigate to Disk Utility and see if you can see the optical drive then.
It's also possible that one of the cables to the optical drive has come undone and needs to be reseated.
On the other hand, I have been reading about optical drive problems on this forum for some time, and some people thing the internal optical drive is just not of the best possible quality. So investing in a good external optical drive may not be a bad strategy.
Good luck!

I have an iphone 4 that I recently upgraded to IOS 7, and now I cant drag music to it. It says "preparing to update" eternally. Weird thing is... I have an iphone 3s that is IOS 6, and it takes new music all day. arg.

I have an iphone 4 that I recently upgraded to IOS 7, and now I cant drag music to it. It says "preparing to update" eternally. Weird thing is... I have an iphone 3s that is IOS 6, and it takes new music all day. arg.
I have tried direct connecting the iphone 4, via wifi, everything. I hate itunes with a passion, but it seems to be a necessary evil. I dont know why I would have no trouble with my iphone 3. I am using the same technique for both phones. Find the music I want in the library and drag it to the iphone. Works on IOS 6, not IOS 7.
WHat else should I try?

Hi jeffmbellucci,
If you are having issues dragging music to your iPhone 4 after a recent upgrade to iOS 7, you may want to verify that the phone is still set to "Manually manage music and videos." You may find the following article helpful:

Arg! Airport Extreme to Extreme- Can't Connect via ethernet

Hello- Arg! Frustrated and can't figure out what's going on.
Goal: Wirelessly connect an airport extreme to another airport extreme and use the 2nd Extreme as a local wired hub.
Problem: Everything works fine, but any machine that is hooked up to the 2nd extreme isn't getting a DHCP assigned and can't see it. But wireless can see it and works great.
Setup: (here goes)
- Airport extreme 1 (AE1) is hooked up to a comcast cable modem. Works great
- Airport extreme 2 (AE2) has been configured to wirelessly join AE1- This also works great.
- 2 Mac pros are connected to AE2 via ethernet cable
visual example:
(comcast) - (AE1) ~~ (AE2) - Mac pros "~" = wireless, "-" = wired
I've tried different machines and cables... no luck. If I reset AE2, they can all connect.
What am I doing wrong here... seems like ethernet is being disabled.
All AE have been updated and along with computer software. All wireless works fine.
Thanks!

Got it... Instead of joining, I had to select extend and ensure that AE1 had extend network enabled. Seems to be working now. Sweet!

Req help in conversion of string to array of args

Hi,
i need help in converting a string into array of args just like command line args
i have a string s1 = 12 13 56 etc
now i want to copy that into an array a[]
a[0] = 12
a[1] = 13 etc
Thanks for help

U can use String tokenizer.Why prefer that over split?Yah Bobby u can use split too..
J2SE 1.4 added the split() method to simplify the task of breaking a string into substrings, or tokens.
Thanks BigDaddy.. I realized after you told.
try this too..
String str = "Your string";
String[] arr = str.split (" ");
for (int i=0; i < arr.length; i++)
System.out.println (arr);

A problem with args[i]

Hi, I'm totally new to Java and I have a problem with my first program. It has to read the numbers from the input and checks wheter it is a prime number.
This is what I have so far:
public class PrimeNumbers
public static boolean isPrime(int n)
if (n<2) return false;
if (n==2||n==3) return true;
boolean prime=true;
int limit=(int)Math.sqrt(n);
for (int i=2; i<=limit; i++)
if ( n%i==0 )
prime = false;
break;
return prime;
public static void main ( String[] args )
int n,i;
for(i=0;i<=args.length;i++)
n=args;
if (isPrime (n))
System.out.println (n+ "is Prime");
else
System.out.println (n+ "is not Prime");
It shows an error in line : "n=args[i];". Can you tell me how to fix it? Thanks :*

Integer.parseInt(args)

Problem opening a file from a command line executed program with args

I have to run my program from the command prompt like this:
c:\ java Parser template.txt keyvalue.dat output.txt
I figured out how to read the args in, and I know they are being assigned to the proper variables. My template.txt, etc are in the same directory that I am in when I run the program. They are also all lowercase, just like the command.
The only error it throws is the one that I coded (Error opening file template.txt) I would make my message better if I knew what the problem was!!!!
Any ideas (either for what I'm missing or how to improve my error handling) :\
Jen

After catching the exception, call the printStackTrace() to have it print out the error it caught, as well as the file and line number it occured on...

GetTreeCellRendererComponent(): get path to value without using row-arg?

I'm using a JTree to display hierarchical data which include cyclic dependencies (i.e. an item may be its own ancestor).
If a node shows up for the second time in a hierarchical tree path, I put a stop to further expansion (using the getPath() of a TreeExpansionEvent in a TreeWillExpandListener), and I give the node a special display (using a tree-cell renderer with a custom implementation of getTreeCellRendererComponent()). The implementation uses tree.getPathForRow(row) to get the path by which can be detected if a node is cyclic, but this does not always work: sometimes tree.getPathForRow(row).getLastPathComponent() corresponds to the value-object given as argument to getTreeCellRendererComponent(), but sometimes it does not.
The example below shows the difference (switch the lines marked "Not OK" by the line marked "OK"; to keep it simple, I left the cyclic dependencies out).
Checking the swing source files reveals that if getTreeCellRendererComponent() is called by paintRow() in BasicTreeUI, value and row correspond. But if getTreeCellRendererComponent() is called by getNodeDimensions() in one of the LayoutCache-classes, the given value-object does not correspond to the object at the given tree-row. Somewhere I read that getNodeDimensions() is called to determine preferred sizes of nodes before they are shown for the first time. If that's the case, it is logical that value and row do not correspond, although I would have liked to get a hint, e.g. a row value of -1.
To detect a cyclic node, I need a treepath, but the row-argument is unreliable. Is there another way to determine the path corresponding to the value-object passed to getTreeCellRendererComponent(), so without having to use the row-argument?

The only general way to hack-around, as far as I remember, is to force the VariableSomething out of the way and make a FixedSomething takes it place. No api, but you can reach that by doing both:
- tree.setLargeModel(true)
- tree.setRowHeight(somevalueabovezero)
Your memory's fine. I ran a short test, this seems to make row- and value-arguments correspond to each other consistently.

... before expanding a node it calls the renderer with the row set to the the row following the row of the node to expand (same for all children)...I suspected something like this, and it opens up a way to solve my question, but it seemed like a too shallow basis for coding. I'm satisfied with fixed row heights, so I'll stick to your suggestion above, and I'll include a short equality test in getTreeCellRendererComponent(), just to make sure:
value.equals(tree.getPathForRow(row).getLastPathComponent())Thanks for the help - Jan

Japanese characters from args giving question marks on Japanese OS

Hi,
We are internationalising our product to japanese, and one of the features is to be able to open a file containing japanese characters from a double click on a japanese windows OS.
The double click is set up in the registry, and indeed it works properly for most characters. There are a few characters though (unicode character 20060 among them) that it doesn't work for, and what happens is that between the double clicking of the file, and the command line name of the file to open ("%1" in the registry / args[0] in java), the character in question is converted into the literal character for "?" (ascii 63), and java can't open the file.
Testing wordpad directly with this character is fine, the file opens. I've written a simple C++ app and a simple JAVA app which fork wordpad with the fileName param passed to it from the registry, and it didn't open the file passed because of that character.
So our java application, a simple java program and a simple C++ program can't resolve the fileName passed to it because of this character.
The thing is, wordpad is using the same regedit method to get its parameters as we do ("appName.exe" "%1" in shell/open/command) and it opens files containing this character without a problem.
Any ideas on what I'm missing?
Thanks very much
Jack

JackUnicode 20060 belongs to an extended part of JIS Kanji code set and there can be many
applications or systems that do not support those characters. Shift_JIS doesn't and
EUC-JP use 24 bit code for representig those chars which, unfortunately, aren't supported

Problem with vmargs at ARGS property in imqbrokerd.conf

Hi @ all,
I'm currently testing Sun Message Queue and would like to give the Queue a little bit more of memory.
I read the docs and tried to set the vmargs parameter at the ARGS property in the imqbrokerd.conf.
But when I try to start the Queue I get a Exception in thread "main" java.lang.NoClassDefFoundError: "-Xms256m error and I'm a bit confused.
My ARGS look like this:
ARGS=-name testqueue-vmargs "-Xms256m -Xmx512m"
I also tested with escaping the like
ARGS=-name testqueue-vmargs \"-Xms256m -Xmx512m\"
but this also doesn't helps.
Could somebody help me with this?
Thanks, NoOne1337

Could it be the missing space?
That won't work...
ARGS=-name testqueue-vmargs "-Xms256m -Xmx512m"
But that, might...
ARGS=-name testqueue -vmargs "-Xms256m -Xmx512m"

JavaFX 1.3 has multiple memory leaks problems:
http://javafx-jira.kenai.com/browse/RT-6921
You are not alone in this issue...actually I didn't know that JavaFX 1.3 applets work on MAC ;)
You'll have to migrate to JavaFX 2.XX and wait for the JavaFX runtime on MAC
