Exec function issue on linux

I have a java daemon process A. Process A uses the Runtime.getRuntime.exec() function to run other java process(es) B at fixed intervals. Both A and B do not display any windows, frames, dialogs , messages etc...
Process A is started via commandline in ...../FolderA:
java - cp .:classesA.jar processA
In Process A, I use the exec function to launch Process B, in ..../FolderB as follows:
String command = java - cp .:classesB.jar processB
String workingDir = ...../FolderB
String envArray[] = null;
prcs = Runtime.getRuntime().exec(command,envArray,workingDir);
On Windows:
1) I can start Process A via commandline on windows, and it runs Process B correctly
2) I telnet to the windows system from linux, and start Process A. It still runs Process B correctly.
On Linux:
1) I start Process A via commandline from RedHat desktop terminal, and it runs Process B correctly, but I get the following message:
Warning: Cannot convert string "<Key>Escape,_Key_Cancel" to type VirtualBinding
Warning: Cannot convert string "<Key>Home,_Key_Begin" to type VirtualBinding..... + 4 more similar warnings
Even with these warnings, process B runs fine and returns with exit code = 0,
2) However, If I telnet to Linux from windows, and start Process B, then Process B fails and returns with exit code = 1. Also, no warning or error information is available from the runtime.exec function.
It seems like an 'environment' issue related to X11 or some shell setting needs to be put into envArray[]. I am not a Unix person and have no idea about fixing something like this. Any inputs would be appreciated.

In the GUI environment (whether you really use it or the JVM just thinks it is needed) the DISPLAY variable has to point to the X server. If you leave it out from the enviroment when exec'ing the second JVM from the first one, then it will become a problem.

SGD 4.5 Desktop Functionality Issue

I've come across an odd functionality issue on SGD 4.5. When I start "My Desktop" everything works fine. However if I start a new Full JDS Desktop session on another server, the JDS session doesn't appear to load correctly. New windows automatically open in the upper left corner and can't be moved. If I close both JDS Desktop sessions and open the other system first, then "My Desktop" session doesn't open windows properly. Has anyone come across this? It's not to big of deal right now, but it might become more of an issue when more users start using our SGD instance.
Adam

@JRoesler :
The script for installing the users during installation when the users are not created is included some version before the 4.50.907
The SGD version here is only 1 minor version before the latest release.
@aspenhedge:
If I look into the rpm (for Linux install) I don't see a check for a valid shell. It does however try to 'su' into those accounts. I might be wrong in this one.
Can you manually use 'su ttaserv' and 'su ttasys' without any problem? Do these users have a valid home-dir for example.

Open a *.exe application in LABVIEW with system exec function.

Greetings,
I would like to be able to lauch a *.exe application and open a specific file within my labview vi. The trick is to avoid using active X control at all cost. I would like to use the system exec function but I couldn't quite get it to work.
Let's assume that I would like to lauch wordpad.exe from my local drive. What are the params I need to pass? Thanks.

You have to type in the command line of the System exec vi the name of the executable and eventually its path.
Look at the attached vi that launches Wordpad as you asked.

Functional Issues w/ IOS7

Depending on how this discussion board works, I will attempt to update functional issues with this operating system.
9/21/13: Alarm: Setting the alarm is rather akward, the numbers are too rigid, fine, and small. I feel the numbers being larger would be more user friendly.
9/21/13 Calendar: Previous version was superior in certain ways. Shading out a part of the day which you typically don't use (ex: 1am-5:30am) would be great. I feel lost in this update, it does not feel refined. Please allow me to send an appointment through imessage already as well!

About "kernel.exec-shield" and "because they will bring security issue" for linux ASE

In " ASE Quick Installation Guide for Linux", "kernel.exec-shield=0" and “kernel.randomaize-va-space=0” should be set.
But SuSE engineers say that “kernel.exec-shield=0”and “kernel.randomaize-va-space=0” will bring the OS security issue.
Customer want to know why ASE need the above parameters ?
Has anybody the idea for customer's question?

If the parameters are not set as documented, attempts to start additional engines beyond the first one will fail, generating stack traces.
ASE acts in many ways like it's own operating system, scheduling individual user connections (spids) to actively run (note that ASE was developed well before native threading was commonly available). Each spid has it's own stack information that gets swapped in when it is set to "running" state on the engine and swapped out when it yields the engine. The mechanics of this is not that different from the buffer overrun exploits described in the Red Hat document linked to by the
install guide, http://www.redhat.com/f/pdf/rhel/WHP0006US_Execshield.pdf
and the exec-shield mechanics definatately interfere ASE's operations when ASE is using multiple dataserver processes (engines) that swap spids around.

Issue in using Runtime.exec for service in linux

Hi,
I have a problem in executing my own service through java6 on linux operating system.
I have created a UI (user interface) which contains a button. On clicking that button my own service gets executed successfully. But the problem is that when I close my UI, my service gets stopped. I want that it should keep running even when the UI gets closed.
I am using this command to start my service in ActionListener:
Runtime.getRuntime().exec("service myservice start");Am I missing something here?
Is this the expected behavior of exec()?

You need to use something along the lines of
        String[] command =
            "bash", "-c", "xemacs > /dev/null 2>&1 &"
        Process p = Runtime.getRuntime().exec(command);
        Thread stderr = new StreamGobbler(p.getErrorStream(), "stderr");
        stderr.setDaemon(true);
        stderr.start();
        Thread stdout = new StreamGobbler(p.getInputStream(), "stdout");
        stdout.setDaemon(true);
        stdout.start();
        int exitCode = p.waitFor();
        System.out.println("Exit code = " + exitCode);where the StreamGobbler class is taken from [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]. You should read all the 4 sections of this article.

EXEC Function in LINUX

Hi,
After processing a flat file in DS, I want to move it to an archive directory.
The command I'm using in a script is
$G_Return_Msg = exec('bash','mv /u02/home/bobje/eric.test /u02/home/bobje/ejtestdir',8);
print('== [$G_Return_Msg] ==');
but it returns the following error message -
== 126: /bin/mv: /bin/mv: cannot execute binary file ==
Can anybody tell me what I'm doing wrong ?
Thanks,
Eric Jones.

you are passing mv commad as argument to bash, this will executed as bash mv a b, which is wrong if you want to open a shell and execute a command in it then pass the command with -c option, check man page for sh, ksh etc
try using the following syntax
$G_Return_Msg = exec('sh',' -c mv /u02/home/bobje/eric.test /u02/home/bobje/ejtestdir',8);
or put this command in .sh file and inovke that script form exec() as below
put the following command in script /u02/home/bobje/move.sh
mv /u02/home/bobje/eric.test /u02/home/bobje/ejtestdir
$G_Return_Msg = exec('/u02/home/bobje/move.sh', '' ,8);

Function issue: inconsistent datatypes?

Hi all.
I'm having an issue with a function that converts coordinates to a spatial data type.

              return v_geometry;

/basically, it takes a list of coordinates, in the following format:
with t as (select '130.88214073599997,-12.377589935499998,0 130.88189276799997,-12.378437734999997,0 130.88164895999998,-12.379271400499997,0 ' coords from dual)replaces the spaces with commas and splits the resultant string by comma, then removes the third coordinate in each set (sets delimited by spaces in above example) and converts the result to sdo_geometry type.
This logic is not where my problem is occurring
If I run the query found in the package separately, it works fine:

REPALCE() function issue. String getting truncated.

Hi,
I am using ORACLE DATABASE 11g. I am facing a very strange problem. I have a string in an variable when i print that sting i can see that the string is correct but after applying a replace function on to it when i print the string the string is incomplete.
Details are as follows :- In the code i am getting some DDL statement (alter table ) , this is the difference between the 2 compared tables. Then I want to place ';' at the last of each line and keyword 'BEGIN' at start and 'END;' at the last. I tried to do this with replace() function but the output string is shot than needed. Please follow the code :-
     dbms_output.put_line('V_TAB_DIFF_ALTER:=' || V_TAB_DIFF_ALTER); -- Print the original string. Variable datatype used varchar2(32767)/CLOB
     dbms_output.put_line('SOURCE Size := '||Length(V_TAB_DIFF_ALTER)); -- Size of the original string.
      V_TAB_DIFF_ALTER_REP :=V_TAB_DIFF_ALTER; -- Placed the sting in new variable.
      V_TAB_DIFF_ALTER_REP := 'BEGIN '||replace(V_TAB_DIFF_ALTER_REP,CHR(10),';') || ' END;'; -- Used the replace function and concatenate string.
     -- EXECUTE IMMEDIATE V_TAB_DIFF_ALTER_REP;
dbms_output.put_line('After replace := '||V_TAB_DIFF_ALTER_REP); -- Now again printing the sting but this time its not proper.The output is as follows :-

NEW Var. Length :- 1862 -- Length of the new string but still the printed string is not the perfect one. It only prints 1830 characters, rest are not printed.
{code}
Here you can see that the sting in after replace in actually short and will give error when trying to execute. As you can also see that length of new string is more i.e. 1862 but its reading and writing only 1830 characters => which is the actual size of original string.
Variable datatypes used varchar2(32767) and CLOB. Faced issues in both the cases.
Its very obvious that when i am trying to replace a few things then I can add a bit more to it. Why is it only reading or writing only the 1830 character string not the whole 1862 string ??? How can i get the size as 1862 but not the whole string ??
Let me know any solution on this ...
Thanks in advance.

Thanks William for your reply.
I have tried with increasing the buffer size by
exec dnms_output.enable(40000000);but still no improvements.
I was able to successful print long strings than this one but when it comes to format it with replace i am facing this scenario.
Let me know if you have any idea.

IPrint functionality gone in Linux iPrint server

We have an application that uses specific fonts that need to be
downloaded to the printer before the job prints. They are PCL fonts.
A long time ago we would capture a printer to LPT1 and then run a
program that would push the fonts to LPT1, then we'd print from the
application.
When we went to iPrint I talked to the iPrint developers and they came
up with a great idea that has served us well. They suggested creating a
print banner that was actually the font file. That way, when anyone
tried printing to one of the printers setup for the application, it
would automatically send the fonts as a banner and things worked great.
That capability is gone in the iPrint for OES Linux. You can no longer
create custom banners so we can't send the fonts. Does anyone know a
way around this? Is anything coming (maybe in OES 2) that will add the
functionality back? Or, does anyone know another way to do it?

Surface Pro 2, Functionality Issues with Photoshop

I've been working with PS for years, and previously used a Cintiq, but i would like to branch out somewhat to a Surface Pro 2 by Microsoft. However, i've been having issues with the way the pen works and how the program reacts to swiping.
I would like to know if i can change the functionality of the button on the stylus on the Surface Pro, as i often have with my Cintiq tablet. Currently it pulls up the brush menu, when i would like it to function as an eraser.
Further, PS seems to react to any upward swipe from my finger by throwing the view of the canvas wildly to the upper corner, rather than a gentle scroll.

Further, PS seems to react to any upward swipe from my finger by throwing the view of the canvas wildly to the upper corner, rather than a gentle scroll.

SAP MII function issue in SAP MII 14.0

Hi,
Currently I was working on some content up gradation work in SAP MII 14.0 , but while working, I have got a strange think regarding SAP MII Functions. We have developed the same code in SAP MII 12.2 and faced the issue while migrating to 14.0. The issue is as follows,
The function we have used in 12.2 is getvalue(name) as in the below screenshot,
but while we have migrated to 14.0, then we saw the function has updated into getvalue(map, key) in 14.0
I have no idea why parameter of the existing function got updated, but the problem is if someone want to migrate the existing code from 12.2 to 14.0 using such of function then he/she can get a "Conversion Exception" and at that time it will become bit hectic to identify the issue and change the logic to handle this in all the places.
Regards,
Suman

Hello Suman,
I guess it is a bug in MII 14.0. The help doc has the getValue(name) still. However, the newer function is not present in the same. I guess it was not documented. I guess, the getValue(map, name) is a newer function which somehow replaced the older one.
I would suggest you to raise a support ticket. According to me, the getValue(name) and getValue(map, name), both should exist.

OBIEE dashboard login issue in LINUX

Hi,
I am getting the following error on LINUX IN presentation server log.
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred.
[nQSError: 12002] Socket communication error at call=recv: (Number=9) Bad file descriptor (HY000)
On Windows its working fine and when i copy the RPD Linux server and try to login its not logging in.
Please help.

Hi User,
It seems to be a Unix server crash.
I have few questions :
1) Are you using OBIEE 10g (10.1.3.4)?. It seems to be a bug on 10.1.3.4 to do with the ldap library.
2)Can you login as Administrator and check the report? . What about the login status for normal user?
If your case is as an adminstrator, you can login and see the report while for a normal user you can't able to view then
Do the following steps to fix the issue: (To start up the OBIEE Server)
abipatst:-$ more StartBIEE.sh
#!/bin/ksh
. $HOME/BIEE/10.1.3.4/setup/sa-init.sh
export LD_PRELOAD=$HOME/BIEE/10.1.3.4/server/Bin/libibmldap.so
$HOME/BIEE/10.1.3.4/setup/run-sa.sh start
$HOME/BIEE/10.1.3.4/setup/run-sch.sh start
Thanks,
