Setting Environment variable in windows xp

Hi all,
I am trying to run a java program in textpad, which is installed in windows XP, but i am getting the following error.
java.lang.NoSuchMethodError: main
Exception in thread "main"
Can anybody tell me, how to set the environment variable in the control panel.
Thanx,
Guddu

java.lang.NoSuchMethodError: main
Exception in thread "main"This error is NOT caused by an environmental variable mis-configuration. It means you did not define a main method correctly, or you are trying to run a class as an application and it is not an application.public static void main(String[] args)

How to Set Environment Variables in Windows

Hi Guys,
You know that we can retrieve the environment variables using System.getProperty("JAVA_HOME"); like this. It is easy.
Can anyone tell me how to create an environment variable using System class or is there any alternate java API to create environment variable. Please let me know.
My requirement is that I want to create the environment variable as follows
DEV_HOME
D:/Java/DEV

Are you talking about Java System properties (get and set through System.get/setProperty) or Environment Variables (read-only, get through System.getenv)?
You can set the former, not the latter (unless you start a new process through Runtime.exec(), for which you can specify a custom environment.

Path and ClassPath:
PATH
In Windows 9x you would set it up in the autoexec.bat file
ie.
SET PATH=%PATH%;c:\jdk1.4.2\bin\;
where c:\jdk1.4.2\ is the path where you installed Java.
In Windows 2000 and XP
Right click on My Computer->Properties->Advanced Tab->Environment Variables... Button.
If you see a PATH in System Variables, click that and edit it. If you don't, you will need to create a new System variable.
It should look something like this:
%SystemRoot%\system32;%SystemRoot%;c:\jdk1.4.2\bin\;

R12, Environment Variables on Windows, and OBIEE

Dear Experts,
I've managed to install R12 on Windows.
Now, in the global environment variable, Path, the user Oracle has a number of directories in its default PATH, starting with the Oracle apps middle tier.
C:\oapps\apps\tech_st\10.1.2\bin;
C:\oapps\apps\tech_st\10.1.2\jdk\jre\bin\classic;
C:\oapps\apps\tech_st\10.1.2\jdk\jre\bin;
C:\oapps\apps\tech_st\10.1.2\jlib;
C:\oapps\apps\tech_st\10.1.3\bin;
C:\oapps\db\tech_st\11.1.0\bin;
C:\Windows\system32;
C:\Windows;
I notice that there are .cmd scripts that set the Path.
This script sets the path to look in: c:\oapps\db
cd C:\oapps\db\tech_st\11.1.0
VIS_black.cmd
echo %PATH%
C:\oapps\db\tech_st\11.1.0\perl\5.8.3\bin\MSWin32-x86-multithread\;
C:\oapps\db\tech_st\11.1.0\bin;
This script sets the path to look in: c:\oapps\apps
set PATH=""
cd c:\oapps\apps\apps_st\appl
VIS_black.cmd
echo %PATH%
C:\oapps\apps\apps_st\appl\au\12.0.0\bin;
I'd like to install OBIEE on the same server. Obviously, I don't want any path conflicts. And, OBIEE uses a different version of java.
1)
Do all these Apps directories need to remain in the global PATH environment variable? Or, can the directories be removed from the path, and the scripts can be relied on to set the appropriate variables?
Thanks a lot!

if you want global settings (always present, even after reboot), you have to edit the autoexec.bat file, e..g
SET CLASSPATH=c:\myclasses
you can set environment variables temporarility in a DOS shell using the same command.
if possible, you should avoid the CLASSPATH environment variable, and use the -cp or -classpath option for java and javac. This helps a lot to solve classpath confusions.

Runtime.exec and setting environment variables

Runtime.exec and setting environment variables
I need a decent example which works on Windows.
Got any?

Thank you.
I was hoping for an example of the use of
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Runti
e.html#exec(java.lang.String,%20java.lang.String[]) or
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Runti
e.html#exec(java.lang.String,%20java.lang.String[],%20j
va.io.File) which take environment variable
information such as PATH.
The reason is because there is a library which is
being loaded via loadLibrary (
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Syste
.html#loadLibrary(java.lang.String) ). However, for
the child process to find the library the PATH needs
to be updated.
Any example regarding changing the PATH variable via
Java so that libraries can be loaded and processes
created? (Perhaps, I should make a new post and
restate the question with this more explicit
information?)
That won't work. LoadLibrary occurs in the JVM environment. As I said you can't change the JVM environment via exec().
If the shared library needs something in the path then you are going to have to set the path before your application starts up.
If you just need to load the library from someplace that is not on the path then you should be using System.load().

Mountain Lion: how set environment variables

Am I correct that for Mountain Lion, if not earlier, the only way to set environment variables at the system level is to use (or create) a file /etc/launchd.conf that contains commands such as:
setenv CATALINA_BASE /opt/local/share/java/tomcat6
(That does seem to work as expected.)
If so, how does one do this by referencing the value of something else, e.g., to set JAVA_HOME? I tried
setenv JAVA_HOME $(/usr/libexec/java_home)
but then in Terminal if I run
echo $JAVA_HOME
I just get back $(/usr/libexec/java_home).
By contrast, if I put that same setenv JAVA_HOME $(/usr/libexec/java_home) command into my ~/.profile, then the result of echo $JAVA_HOME is the actual value referenced, namely, /Library/Java/JavaVirtualMachines/jdk1.7.0_15.jdk/Contents/Home.

Linc Davis wrote:
launchd is not a shell and does not peform expansion. You have to use literal expressions. But you can also modify the bash environment system-wide by editing the file /etc/profile.
But sudo emacs /etc/profile won't let me edit this file: it's read-protected, emacs says.
What permissions should I give it? Right now it's in group wheel, owned by root but with Read permission only.
P.S. And is it really a good idea to edit /etc/profile -- assuming I can suitably set the permissions to do so? Apple goes out of its way to try to hide this file: /etc is a link to /private/etc, e.g.

Forget to set environment variable export SAPINST_USE_HOSTNAME

Dear Experts
we have installed the SAP ECC6.0 EhP4 in HACMP environment with AIX6.1 ,Power HA cluster6.1, oracle 11g database
the problem is while installing the CI and ASCS and Dialog instance I missed to set environment variable
export SAPINST_USE_HOSTNAME = <virtual Host Name> and while starting the sap-inst also i didn't start as like
./sapint SAPINST_USE_HOSTNAME = <virtual Host Name>,Now i am facing problem while doing cluster fail over to another node
Node A host Name is not reflecting in Node B and I am not able to start the SAP with host name of Node A
in AIX6.1 in IBM Admin they didnt give any virtual host name they said that they have configured the cluster with two service IP there is no virtual IP in AIX6.1
please help me out how to resolve this host Name issue and to start the SAP in Node B
Thanks in Advance
krishna

Hi Krishna,
I dont agree with the AIX 6.1 having no virtual ip's, because i recently installed a HA instance with ASCS, SCS & also ERS on 6.1
to answer your questions:-
"can you tell is this correct setup or anything we did mistake for file system setup and installation"
This depends on what your requirement is. Typically a cluster will have Oracle on one host and SAP on the other host. Ill explain the VCS concept, so you will have a better understanding.
Lets consider Node1 & Node2. Now each node will have a physical IP and a virtual IP. The Virtual IP will be associated with a set of file systems. For example /oracle will be associated to virtual ip lets say "xyzDB" & the /usr/sap/<sid>, TRANS & sap mount will be associated with virtual ip lets say "abcCI". Now when the cluster fails over to which ever node, these file systems will still be associated with their respective virtual ip's.
So, the start profile will always have START_DVEBMGS_abcCI. Irrespective of which Node the sap is in, when you start the SAP, it will use the virtual hostname and start up SAP. I hope your getting the concept.?
Coming back to the setup, since you have ASCS, Oracle , CI & a dialog instance. Im not sure what file systems you have associated with VCS groups. Can you give command "hastatus -sum" and post the output?
Regarding your other question
"this file system is moving to Node B but while starting SAP on Node B host Name is not reflecting and SAP is not coming up due to there hostname didnt change in Node B,, can you advice me please ,,"
This is inline with what i explained above for cluster mechanism. The physical IP will not change. It is only the virtual IP that is associated with a set of file systems.
Ill give you one more example, Consider the parameter rdisp/mshost = <> . What should this be? Physical host or Virtual host?? :-) .It should be Virtual. Because the CI can be in Node1 or Node2. If we give the physical host, then if the SAP fails over to the other node. How will it start up? because the profiles still say the message server is in the other host... Getting my point?

Setting environment variables remotely doesn't work for Windows 7

Hi,
$RemoteMachineList = 'machA', 'machB'
$session = New-PSSession $RemoteMachineList
Invoke-Command -Session $session {[Environment]::SetEnvironmentVariable("Role",0,"Machine")}
The above is the code snippet which I've tried for setting a machine level environment variable. After executing this code in a collection of XP and Windows 7 machines, when I go and check the advanced settings->system environment variables, I can see
the new entry "Role" in all the machines. But unfortunately, this env variables actually gets set only in XP machines(I did a set command from a cmd prompt/or an echo command) whereas in Windows 7 machines, this doesn't exists even though it
shows up in the advanced settings->system environment variables.
Tried in several machines, only Windows XP is yielding the required result.
Please help.
Thanks in advance !
-Aravind

Thanks Chen, but still the same result.
I'll narrow down the scenario(actually two scenarios) as per the way it's behaving on Windows 7 machines.
Case - 1
1. I do a SetEnvironmentVariable remotely.
2. I go to that remote machine and search in advanced settings -> system env variables window. Dont click on the OK Button. Close these windows.
Result: Yes it is there as an entry.
3. I open up a command prompt and type 'set'
Result: No it is not set.
4. Again open up advanced settings -> system env variables window. Click on the OK Button. Close these windows.
5. Now open up a command prompt window and type 'set'
Result: It is set now
Case 2:
1. I do a SetEnvironmentVariable remotely.
2. I go to that remote machine and search in advanced settings -> system env variables window. Dont click on the OK Button. Close these windows.
Result: Yes it is there as an entry.
3. I open up a command prompt and type 'set'
Result: No it is not set.
4. I do a system restart.
5. Open up a command prompt and type 'set'
Result: It is set now
Any idea why this is behaving like this(more or less like setting a user level env variable), please ? I've to some way get through this obstacle to advance further. Thanks a lot for the support

Setting ORACLE_HOME as Environment variable in Windows

Hi,
I have a problem.
I am using Oracle Application Server 9.0.4. on Windows 2000 server .
There are 2 homes, one for mid tier and one for Infra.
Now when I look in PATH variable of the environment variables, i can see both homes specified there.
But when issue echo %ORACLE_HOME% from command prompt then i can see nothing.
And there is no ORACLE_HOME environment variable, so i created a ORACLE_HOME variable and assigned the Oracle home path to it.
Now when i issue the command echo %ORACLE_HOME% i can see the value of the ORACLE_HOME,
So is this the correct way to set the ORACLE_HOME?
Is this the way to create the ORACLE_HOME environment variable.
Thanks & Regards,
Avinash.
Pune.
India.

So is this the correct way to set the ORACLE_HOME?
Is this the way to create the ORACLE_HOMEenvironment
variable.No. Not on Windows platforms.
The Oracle Home paths are already set via Windows
Resgistry values. Check HKLM\Software\Oracle\ (HOMEx
or KEY_<home name>) for ORACLE_HOME settings.
This is used by programs via PATH and when calling a
program that uses the oracle.key files from OH\bin.
Setting it via system environment could override
individual settings, which may lead to unwanted
results or issues.True for some areas.
And yet, for Patching you MUST set the Oracle_Home variable, in which case Virag's response is the correct method.

Setting Environment Variable CPIC_MAX_CONV

Hi Experts,
In of the steps during POST INSTALLATION of PI7.0 it says to set the variable CPIC_MAX_CONV, using the transaction RZ10.
When i logged in to the abap system , and checked in RZ10,did find any variable of this name.
Do I need to create it first and then set the value gw/max_conn_per_wp.
If yes, give me the steps to do this. or else any other alternative.
Thanks in advance,
