Executable behaving different when called f/Java

I have an executable that is run from the command line which behaves differently when I run it from my application. The executable takes MP3s files as arguments and merges them together. When I use large files from within my app, it doesn't respond, but using the same files from the command line works fine. I was thinking it might be a memory thing, but the executable should get its own space seperate from the VM. Does anyone have any suggestions? Thanks!

I do not have the source for the executable, so I wouldn't be able to pull lines out of there. It works from my Java app when I pass in smaller files, so I know I have the syntax correct, but with larger files it hangs. When I run the same thing from the command line with the larger files it runs like a champ. I was trying to use my task manager (I'm on Win NT) to look at memory usage since the only variable seems to be file size, but nothing seems to indicate it is a memory issue.

Query behave strange when called from java

Hi,
I had the same scenario a few times in two different queries in different databases (10g v2) and so not putting the query.
When I run the query from sqlplus/toad it takes less than a second
When I run it from java it takes about 5 minutes.
I could have thought it is something to do with Java ...
But when I rename the underlying table and use the new name in the query it takes normal (less than a second) time both in java and sqlplus/toad.
Before changing the name, I have tried rebuilidng the indexes and analyzing the table. The table has about 10 million rows and 13 indexes in one scenario and as less as 400k with 3 indexes in the other scenario. and in both cases updated once daily.
Each time this happends either a rename or dropping and recreating the table is solving the problem. I am lost.. any ideas what might be causing this problme; any solutions.
Thanks

Do whatever it is you are doing that makes it faster and run an Explain Plan capturing the output with DBMS_XPLAN. Also save off the stats collected on the table and indexes
Then, when performance deteriorates capture another plan along with the stats.
What is different?
A table with 13 indexes is an indication of an issue. I would suggest someone take a good look at why so many indexes are there.

Why does "Link Media" behave differently when used as a keyboard shortcut vs when right clicked???

Not sure whether anyone else is encountering this, but the "Link Media" command behaves differently when right clicked as opposed to when used as a keyboard shortcut.
When you right click to select that option for an offline file, you get only the corresponding disconnected source media. But when you execute "Link Media" via a keyboard shortcut, PP brings up a huge list of all other offline media. Why does it only do that when you use the keyboard shortcut for "Link Media" but not when you right click "Link Media".
I'd like to get the Link Media command to behave via the keyboard shortcut the same way it behaves when right clicked. I don't want to have to deal with relinking a hundred other files, but just the single offline file I'm working on.

Among the alternatives not mentioned... Using a TiVo DVR, rather than the X1; a Roamio Plus or Pro would solve both the concern over the quality of the DVR, as well as providing the MoCA bridge capability the poster so desperately wanted the X1 DVR to provide. (Although the TiVo's support only MoCA 1.1.) Just get a third-party MoCA adapter for the distant location. Why the hang-up on having a device provided by Comcast? This seems especially ironic given the opinions expressed regarding payments over time to Comcast. If a MoCA 2.0 bridge was the requirement, they don't exist outside providers. So couldn't the poster have simply requested a replacement XB3 from the local office and configured it down to only providing MoCA bridging -- and perhaps as a wireless access point? Comcast would bill him the monthly rate for the extra device, but such is the state of MoCA 2.0. Much of the OP sounds like frustration over devices providing capabilities the poster *thinks* they should have.

Out of memory error when calling a java stored procedure multiple times

Trying to run a PL/SQL loop calling a java stored procedure, I get the following error:
"ORA-04030: out of process memory when trying to allocate 262188 byte callheap,ioc_allocate free)"
(with some other error lines).
The stored procedure does two major things:
1) Open a socket to communicate with a server, of which it queries some data.
2) Use JDBC (with the default DB connection it has, as a stored procedure) to write the results to a table.
All socket connections, statements, etc. are properly closed and all memory should be garbage collected between each call.
Can anyone offer an explanation or additional checks to make? I'm quite sure the code isn't causing the problem, since I've tried running it as a stand alone application (outside of Oracle) and didn't have any problems.
Thanks.

Type conversion when calling a java program in form 6i

Hi,
I would like to call a java program in form 6i. The java program takes a date parameter in. When I call the java program in form, how can I pass a date parameter to it?
-- Method: isSystemDate (Ljava/util/Date;)Ljava/lang/String;
FUNCTION isSystemDate(
obj ORA_JAVA.JOBJECT,
a0 ORA_JAVA.JOBJECT) RETURN VARCHAR2;
Thanks.

hi Tony,
Perhaps you could notice that i myself commented in the beginning itself that I know that XE does not support JAVA. I wanted to know if there is any other way of calling java program from apex, perhaps from javascript,etc.
if you RE READ the comment from Munky , he says that I could use PL/SQL for my objective and I have answered WHY it does not satisfy my problem
thanks

Code behaves differently when run in debugger

var he:Array = handControl.getHumanInfo(ha, handNumber);
while (he.length != 0)
humanInfo.push(he.shift());
This snippet is part of a large flash project I am working
on. The program works fine by itself, but when I try to step
through it in the debugger, it sometimes crashes, depending on
where I put a breakpoint. If I put the breakpoint on the first line
of code above, I can step into the function getHumanInfo(), trace
it, and step back out, and everything is fine. But if I only put a
breakpoint somewhere inside the getHumanInfo() function, all of a
sudden when I step out of that function, the variable 'he' is
undefined, and so the while loop never ends.
This makes no sense to me. The code is either good or bad, it
shouldn't behave differently based on where I put the breakpoint.
The getHumanInfo() function always creates a new array and
passes it back, so there is no reason 'he' should be undefined.
This has happened many times when I've tried to use the flash
CS3 debugger -- is there a known issue that this sounds like? I'm
so fed up I'm ready to stop using the debugger altogether.

I ran the program without the debugger and put some trace()
statements in, just to make sure. Everything works fine without the
debugger. So it seems to me it has to be a debugger issue. Has
anyone heard of a similar issue?

How stored procedure get executed when called from java

When we create a stored procedure or function in oracle, it is compiled and stored there. From java when we call them no compilation is performed its a simple call. When a function or stored procedure is invoked from multiple instance of java objects(for a single session), does the stored procedure clone it self so that it can be called by different java objects which I think not possible at all. In such cases when one java object is interacting with the stored procedure, does other java objects go on a wait state. What happens if sessions are different.
Please help.

>
does oracle creates multiple instance of a particular stored procedure for different sessions or connections. if not then there might be some kind of waiting principle followed.. what happens exactly
>
What happens exactly is detailed in Chap. 14 Memory Architecture ni the Database concepts doc
http://docs.oracle.com/cd/E14072_01/server.112/e10713/memory.htm#i21266
The code is shared but the data isn't (see the lone exception to this below).
See the section on the Library Cache
>
Program Units and the Library Cache
The library cache holds executable forms of PL/SQL programs and Java classes. These items are collectively referred to as program units.
The database processes program units similarly to SQL statements. For example, the database allocates a shared area to hold the parsed, compiled form of a PL/SQL program. The database allocates a private area to hold values specific to the session that runs the program, including local, global, and package variables, and buffers for executing SQL. If multiple users run the same program, then each user maintains a separate copy of his or her private SQL area, which holds session-specific values, and accesses a single shared SQL area.
>
The exception is when code uses the SERIALLY_REUSABLE pragma. In that case the memory for package state is in the SGA and users do not have their own copy in their UGA.
See the SERIALLY_REUSABLE pragma in the PL/SQL Language doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/seriallyreusable_pragma.htm
>
The global memory for serially reusable packages is pooled in the System Global Area (SGA), not allocated to individual users in the User Global Area (UGA). That way, the package work area can be reused. When the call to the server ends, the memory is returned to the pool. Each time the package is reused, its public variables are initialized to their default values or to NULL.
Serially reusable packages cannot be accessed from database triggers or other PL/SQL subprograms that are called from SQL statements. If you try, the database generates an error.

Applescript in Automator behaves differently when executed from inside Automator, or as an Automator application

Hello everyone,
I'm trying to execute an Automator workflow at startup, which I do by saving the workflow as an application, and adding it to the startup list, this works fine.
My workflow works fine when executed from within Automator (ie clicking on the "Execute" button), but does not anymore when the Automator application is executed (ie. simply double clicking on my Automator file)
I have narrowed it down to an Applescript inside my workflow which fails only when the application is executed from the finder (the step works fine from within Automator). The script automatically creates an ad hoc wifi network.
The line which specifically fails is :
set menu_extras to value of attribute "AXDescription" of menu bar items
Anyone has any idea why executing the workflow from within automator, and executing it from the finder yield different results ?
The crazy thing is that all this worked fine up until a few days ago, there might have been an update since (running Mavericks 10.9.2), but nothing game-changing.

You will need to provide more than the one line of AppleScript you quote if you want a definitive answer. (We can't even see which app you are addressing this to.)

Java application behaving differently when run from netbeans

Hi,
When i run my program from netbeans it receives packets from ip addresses which are not in my subnet
but when i run it from outside netbeans it doesn't receives packets from ip addresses which are not in my subnet.
Can anybody explains why my application is showing different behavior when run from netbeans and when run independently?
Thanks.

Bingo! My script started the rmiregistry and continued on to start the servers. Apparently, it was too quick. I put a 10 second delay after the rmiregistry startup and all is working as it should.
Thanks for your help. You get the Duke dollars if I can figure out how that works.

'create table..' statement behaves differently when alone or in a SP

hello
sorry for the title, I just couldnt think of a better description of the problem in very few words...
the problem I have is:
I created a stored procedure into the oracle db, and this procedure has the following code inside it:
auxsql := 'create table tmp (id smallint, name varchar2(256))';
execute immediate auxsql;
- now this procedure I call from a java class, using a callable statement
when I call the stored procedure, I get this message:
ORA-01031: insufficient privileges (at the line containing the execute instruction)
my dillema arises from the fact that if I change my callable statement to execute a query of the form:
auxsql := 'create table tmp (id smallint, name varchar2(256))';
execute immediate auxsql;
- but executed as is, not embedded in a sp or something;
- so if I change to execute simply this, all goes well....
I would much appreciate if anyone knew at least where to start looking.
Thank you,
Silviu Lipovan Oanca
p.s. for any further details, just say.

In all probability, the user that owns the stored procedure has the CREATE TABLE privilege through a role, not granted directly. In PL/SQL blocks (assuming definer's rights), only direct privilege grants are "visible", whereas straight SQL statements also "see" privileges granted through a role.

Fatal PL/SQL error when calling imported java code

Hi,
I'm developing reports using Report builder 9.0.2 under Win2k and I have the following problem:
I select data into fieds A and B.
I created 2 formulas fA and fB that call a PLSQL function from my report in order to convert A and B based on other data.
I also have a formula fC which is actually fA-fB
I have 3 summary columns on fA, fB and fC. I don't display any of those columns on the report but I created other formulas columns fA_Fmt, fB_Fmt,... to format the values using an imported java class.
This java class is static.
so fA_Fmt looks like this:
function fA_Fmt return Char is
begin
return MyJavaClassPackageName.formatValue( :fA, report_global_variable );
end;
When I run my report under report builder, I get a REP-1401 report error like "fA_Fmt formula: fatal PL/SQL error occured
ORA-39565: Message not found, product RDBMS, facility: ORA"
This happens randomly on any of the formulas.
Sometimes I even get a java.lang.StaskOverFlowError and I have to close and restart report builder.
I've tried to debug and I even caught the exception.
The parameters passed to the java method are fine.
The exception number is 105101 and after a couple of exceptions like this, visual C++ runtime library tells me there's a runtime error in rwbuilder.exe and the application crashes.
I don't know if it's Java, if it's Report builder or even Win2k.
Anyway, I'm stuck with that and I don't know what to do to fix it.
Any idea or work around?
Thanks
Manu

Hi Manu
I suspect the line given below:
return MyJavaClassPackageName.formatValue( :fA, report_global_variable );
Do not pass report values directly. Instead, assign it to a temporary variable and try again. See if this works:
temp1 <Variable_Type>;
temp2 <Variable_Type>;
temp1 := :fA;
temp2 := report_global_variable;
return MyJavaClassPackageName.formatValue( temp1, temp2 );
Note: You may also hit Fatal PL/SQL errors if the arguments happen to be invalid.

Why does terminal behave differently when logged in as different users?

when I'm logged into my mba as my regular normal user, bash behaves normally; but when I create a new user or use any user other than my default the behavior is different. (might be bash or sh)
Specifically, the tab autocomplete function works fine when I'm logged in as my regular user (tab-complete; tab twice for all available selections/options).
But on a newly-created user (also an admin) there is no tab complete, no 'tab twice, other options' etc.
Has anyone else seen this?
I searched in this forum and found some instructions for creating an .inputrc file but I don't appear to have one on my default user so not sure why I would need this on the new user ?!?!?
p.s. here are the instructions I found previously via a post on this forum:

JavaFX hangs when called from Java

Hello
I am developing a java application with a JavaFX gui, the communication from Java works with an java interface. The communication works,but after a few updates the javaFX code hangs and subsequently the Java code also hangs.
Is this a common problem, and so is there a common solution for this.

JavaFX UI calls need to be done on the Event Thread. So if your Java Application has multiple threads or runs on a different Thread to need to wrap all callbacks to JavaFX in a deferAction like this:
class YourFXClass extends YourJavaInterface {
   override public function someMethod(someArgument) {
        FX.deferAction(function() : Void {
              // doSomething with someArgument
    }

IE6 leaks "Handles" when calling *ANY* Java applet

Hello all IE experts,
It seems that IE has "Handles" leak when it calls Java Applet.
Every call to a Java method from JavaScript, IE allocate a handle and does
not free it.
THIS DOES NOT HAPPEN when I use mozilla or Netscape.
Versions:
* Windows 2000 SP 3 (The most recent, with all fixes of hfnetchk)
* Internet Explorer (The most recent one, with all fixes of hfnetchk)
Version 6.0.2800.1106
SP1
Q328970
Q324929
Q810847
Q813951
* Java Plug-in - 1.4.1_02-b06
If you compile the applet and use the test html, then press "Test" you will
notice that 1000 (or more) handles are allocated (At Windows Task Manager).
If you press again you will see that another 1000 (or more) handles are
allocated. The handles are NEVER released, even if you browse to other
sites. You can enjoy this process until there are no more handles to
allocate... :)
Notice that the applet I use does nothing... I've checked this with various
of applets on the web and the results are the same.
Can anyone help?
