Setting Linux environment variable

Is there other web site which talks about how to set the environment variable of J2EE for Linux?
I followed this web site
http://www.dougsparling.com/comp/howto/linux_java.html
but after all
when I tired to compile a servlet program... it couldn't be complied. I think the case is that the compiler couldn't find servlet.jar ...
why is that?

You have to verify that your CLASSPATH environment variable is set in your account's profile. I use the
bash shell therefore my variables are set in .bashrc
for example my CLASSPATH is set to :
CLASSPATH=.:$J2EE_HOME/lib/j2ee.jar:$J2EE_HOME/lib/locale

Setting new environment variable on Linux

{noformat}I need to set new environment variable on my linux machine from inside my code. I am using csh and the command works fine from command line:
setenv IFConfigLocation4 /home/username/myfile.xml
But when i try the same thing from Java code it does not seem to have any effect. here is my code:
import java.util.*;
import java.io.*;
public class CDE_parser_methods{
public static String fileParse(String inFile, String parserName, String outFile, String CMConfig_locale)
String parsed = "SUCCESSFUL";
System.out.println("Parsing file..." + "\nParser name: " + parserName +"\nInput file name: " + inFile + "\nOutput file name: " + outFile + "\nCMConfig file is: " + CMConfig_locale);
System.out.println("Current Java version: " + System.getProperty("java.version"));
try
          String cmd[]={"/bin/csh", "-c", "setenv IFConfigLocation4 " + CMConfig_locale};
          Process proc = Runtime.getRuntime().exec(cmd);
          int exitVal= proc.waitFor();
          System.out.println("Value of setenv command is: " + exitVal);
          String cmd2[]={"/bin/csh", "-c", "env"};
          Process proc2 = Runtime.getRuntime().exec(cmd2);
          InputStream instr = proc2.getInputStream();
          InputStreamReader inread = new InputStreamReader(instr);
          BufferedReader buf = new BufferedReader(inread);
          String line=null;
          while((line=buf.readLine()) != null)
               System.out.println(line);
          int exitVal2= proc2.waitFor();
          }catch(CMException cme){
               System.out.println("Issue when trying to executing parse command, details: " + cme.getMessage());
               System.out.println("Description of the issue is: " + cme.getDescription());
               parsed = "FAILURE: " + cme.getDescription();
          }catch(Exception e){
               System.out.println("Uncought exception, details: " + e.getMessage());
               parsed = "FAILURE: " + e.getMessage();
     return parsed;
public static void main(String[] args) {
     String results=CDE_parser_methods.fileParse("/opt/itemfield/ServiceDB/Project2/Mapping_for_Account_Number_Structure_ITS_Input_File.xls","MappingforAccountNumberStructure","/opt/itemfield/ServiceDB/Project2/test_ws_44.xml","/home/rvenishe/CMConfig.xml");
     System.out.println("Result of fileParse call is: " + results);
     }The out put of my env command does NOT contain system variable "IFConfigLocation4". Any ideas? {noformat}

Environment variables and their values set from within a user process has their scope and lifetime limited to the process and its subprocesses. See java.lang.ProcessBuilder class and its API documentation for setting env for a subprocess that will be started by a ProcessBuilder instance. Even in the C programming we have the same limitation for the environment.
Since they are not globally set, system command like env or Java method like System.getenv() can't see them.

Set DISPLAY environment variable -- in DBCA not working at AIX OS

Hi,
I want to create new database in AIX OS and database is oracle 10g:-
When i say DBCA it is giving below error, what should i do?
$ dbca
DISPLAY not set.
Set DISPLAY environment variable, then re-run.
Please help...

How to set the DISPLAY environment variable in AIX?Usual format is:
+<host>:<display-number>+
E.g.
export DISPLAY=192.168.0.235:1
Where the host is the hostname or IP address of the client platform running a X-Server. If the X-Server is running locally, then this entry can be omitted.
The display-number is the display number of the X-Server to use. A single X-Server can have multiple displays. E.g. Unix server running a X-Server can have 10 users connected via X-Terminals and will this have 10 displays.
Judging from X-Windows questions asked on OTN, it seems to be a tad complex to grasp for some - especially those from a MS Windows background as X-Windows is very different and also reverses the client-server concept, requiring the X-Server component to be running on the client platform (where the server platform runs the program that is the X-client).
So it is a lot easier to rather use something like VNC instead - supported on most Unix platforms, Linux, Windows and Apple's OS/X.
Simply run the VNC server on the server platform to create a virtual container for running the X-server display. Connect from a client using a VNC client.
As it uses the RFB (Remote Frame Buffer) protocol, it is a lot faster than running the slower and larger X11 protocol required for X-Windows connectivity over TCP/IP.

How to set the Environment Variable

I'm going through a tutorial on how to create an application and run from the command prompt. I have finished installing my jdk 6 Upadate 5 but i don't know how to set the Environment Variable for the javac compiler and the java interpreter to find my program.
I have created an application called "ExampleProgram" and have saved it on drive C:. How do i set the Environment Variable so that the "javac" compiler and the "java" interpreter can find it

I Google and had several information on how set it, but i tried all of them and none seem to work.I typed "how to set environmental variable in winxp" in Google and the very first link provided all the information I needed (you need). These things will make much more sense if you go through it yourself rather than having someone else spoon-fed you the answer.

Why do we actuallya need the setting of environment variables?

Hello guys,
I read that, in order to connect to the database via SQL*Plus, we need to have the environment variables set. So, SQL*Plus is a command tool, which doesnt know over which path to connect to db, if the environment variables are not set?
How about the needs of setting environment variables at point of view of MS-DOS? I know that over MS-DOS we can check if the environment variables are already set or not. Or we can actively set the environment variables.
When should we actually set the environment variables? Before we run the GUI or after? I read, that if we set it before we run the GUI, then the setting will be taken over when it comes to that step by running GUI. I am curious, since this would be interesting to know, if we use other version than XE.
Thanks..

Oracle's flexibility ... many different versions working the same on many different versions of many different operating systems ... means that a single consistent installation and configuration methodology must work everywhere so as not to have the limitations of other competing products that work on only a single operating system or require that one learn a different syntax and methods for different versions.
Be grateful Oracle is as it is. Your competence in one version and operating system translates into competence in others.

Setting the environment variable

I just installed the rpm for the 1.4 SDK on my RedHat 7.1 box. Does anyone know how I can set the environment variable so it will recognize Java from the command line? Thanks in advance.

You need to set a couple of environment variables in your "profile" script. Which one, exactly, depends on the shell you use. It's probably .profile on your home directory.
Try
JAVA_HOME=/usr/java1.4 (or wherever it really is)
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME,PATH

I want to set Jdeveloper environment variables

First,thanks for your answer.But I mean to set Jdevelop
environment variables.If I can't set right Jdeveloper
enironment,program can't pass the compile.Because "import
oracle.html.*" can't be found by Jdeveloper.
null

Hi
You would need to include jweb.jar file as a library in your
project properties.
jweb.jar comes with Oracle Application Server. Copy the jar file
to lib directory in JDeveloper and add it as a library to the
project.
This would make import oracle.html.* work.

Linux Environment Variables

I have tried several times to set the environment variables. I have tried pointing to /usr/local/java/j2sdk1.4.0/bin and this does not work. This is where the sdk is located, so why would this not work. All the documentation says to point there. Any help is appreciated on how to get this working.

I assume you are using bash. Did you try to say:
PATH=/usr/local/java/j2sdk1.4.0/bin:PATH
and then invoke your javac or java?
Having "said" that, the setting will however apply to that command shell and will not affect the other ones.
To set this permanently, you might consider including this line into your .profile file.
I use a more flexible solution, as I have several jdk's installed and I want to switch among them from time to time.

How to set timezone environment variable to EST

Hello Experts
I'm having problem when I try to run my Enterprise Manager. Listner start normaly but then I tries to start the database I got the following message.
oracle@linux-f4y3:~> /apps/oracle/product/10.2.0/db_1/bin/emctl start dbconsole
Oracle Enterprise Manager 10g Database Control Release 10.2.0.1.0
Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved.
http://linux-f4y3.site:1158/em/console/aboutApplication
Timezone mismatch: The agentTZRegion value (EST) in
/apps/oracle/product/10.2.0/db_1/linux-f4y3.site_orcl/sysman/config/emd.properties
does not match the current environment TZ setting(EST).
The dbconsole cannot run with this mismatch.
If EST is the correct timezone, set your timezone environment variable to EST and repeat the 'emctl start dbconsole' operation.
If EST is not the correct timezone, make sure that the timezone in your environment is correct, and then run the following command in your local Oracle Home: 'emctl resetTZ agent'
The output of this command will include detailed instructions to follow, to correct the mismatch.
To me looks like I need to fix the timezone on my machine but I don't know how. Can please somebody shows me the steps how to achieve this task?
Thanks a lot in advance.

I believe this issue is occurring because timezone info between the OS and oracle is out of synch - possibly because timezone patches have been applied to the OS or oracle, but not both. It is always good practice to apply such patches to both OS and Oracle.

How do you set NLS_LANG environment variable in report builder

How do you set up the reports builder environment to display foreign fonts.
So far what I read makes me think that in report builder I have to set the NLS_LANG environment variable .
If anyone has done this is that true and if so how.
Also the languages I want to use are the following.
Armenian
Cambodian
Chinese
Russian
Tagalog
Vietnamese
How do I find the NLS_LANG environment variables for these.
Where I am at now+
I have to set the DEVELOPER NLS LANG. I see the NLS LANG in the registry and I guess I have to add the DEVELOPER NLS LANG.
Now I am searching for syntax. If anyone knows the syntax for those languages please let me know and how do I set more than 1 at a time.

Hello Howard,
Check out the following link here you can find your desired NLS parameters.
http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm
And about the NLS_LANG for developer why you want to create for developer. Its is already there in REGISTRY. Just seaching in developer registry you can find there.
how do I set more than 1 at a time.
You can set only one NLS_LANG parameter at a time.

Best practice for setting an environment variable used during NW AS startup

We have installed some code which is running in both the ABAP and JAVA environment, and some functionality of this code is determined by the setting of operating system environment variables. We have therefore changed the .sapenv_<host>.csh and .sapenv_<host>.sh scripts found in the <sid>adm user home directory. This works, but we are wondering what happens when SAP is upgraded, and if these custom shell script changes to the .sh and .csh scripts will be overwritten during such an upgrade. Is there a better way to set environment variables so they can be used by the SAP server software when it has been started from <sid>adm user ?

Hi,
Thankyou. I was concerned that if I did that there might be a case where the .profile is not used, e.g. when a non-interactive process is started I was not sure if .profile is used.
What do you mean with non-interactive?
If you login to your machine as sidadm the profile is invoked using one of the files you meant. So when you start your Engine the Environment is property set. If another process is spawned or forked from a running process it inherits / uses the same Environment.
Also, on one of my servers I have a .profile a .login and also a .cshrc file. Do I need to update all of these ?
the .profile is used by bash and ksh
The .cshrc is used by csh and it is included via source on every Shell Startup if not invoked with the -f Flag
the .login is also used by csh and it is included via source from the .cshrc
So if you want to support all shells you should update the .profile (bash and ksh) and one of .cshrc or .login for csh or tcsh
In my /etc/passwd the <sid>adm user is configured with /bin/csh shell, so I think this means my .cshrc will be used and not the .profile ? Is this correct ?
Yes correct, as described above!
Hope this helps
Cheers

Setting JAVA_HOME environment variable?

Sorry for such a trivial question, but in Windows 2000 Server with Microsoft Visual J++ 6 and the JRK 1.1.8, can somebody tell me what the environment variables should be so that I can use this jdk? If not can you tell me what your environment variable JAVA_HOME points to?
And one last question if it's not too much to ask. Can you tell me the NNTP server address for SUN so that I can go to the newsgroups in my News reader rather than over the web?
Thanks.
George Hester

Thanks. I have a problem though. I installed the jdk 1.1.8 because I heard that was the last one supported using Visual J++. Hence I have a C:\jdk1.1.8. This folder has no JRE subfolder so I am stuck at what you said the Classpath should contain as the path\folder you say it should be does not exist.
I have a folder C:\Program Files\JavaSoft\JRE\1.3.1 which has the lib folder containing rt.jar.
So as you can see I'm sort of in a quandry.
If I make JAVA_HOME as you say then it does not contain the JRE. If I make JAVA_HOME C:\Program Files\JavaSoft so that your suggestion for Classpath is correct that folder does not contain the jrk and it seems that I will not be using it.
Any suggestions how to set this up so that it's right?

How can I set PATH environment variables when there is no ~/.profile?

Hi,
I have a MacBook Air and just installed MySQL.
I read the doc which I downloaded and should be able to run "mysql" from terminal as descibed below:
Suppose that your MySQL programs are installed in /usr/local/mysql/bin and that you want to make it easy to invoke these programs. To do this, set the value of the PATH environment variable to include that directory. For example, if your shell is bash, add the following line to your .bashrc file:
PATH=${PATH}:/usr/local/mysql/bin
I checked on my terminal with ls -al, but no ~/.bashrc also no ~/.profile files. Echo $SHELL shows me that I am using /bin/bash as shell.
When I run export PATH=$PATH:/usr/local/mysql/bin then it works and I just have to type "mysql" to get the mysql command line but as soon as I kill my terminal and open a new terminal this setting is lost.
Any idea how I can accomplish this?
Thanks,
MacNewby

Hi,
Never mind, I found it :-)
I just created a file .bash_profile in my home folder and added "export PATH=$PATH:/usr/local/mysql/bin" and restarted my terninal. Now it works.
