Update JDK environment variables...

Oracle 11g RAC RHEL 4 AS
I have just upgraded JDK from 1.4 to 6.0 and I wanted to know where and which environment variables need to be updated.
Thanks.

Well, I have just finished upgrading my RAC database to 11g. And in the deprecated section, it is mentioned that JDK 1.4 is not supported for 11g and we must upgrade to 1.5 or 5.0. So I upgraded to 1.6 but I still get the error:
Exception in thread "main" java.lang.UnsupportedClassVersionError: oracle/ops/opsctl/OPSCTLDriver (Unsupported major.minor version 49.0)

when I give the the srvctl stop instance command. I am thinking maybe I need to point the environment variables to the correct java version? Perhaps I need to edit the $ORACLE_HOME/bin/srvctl file?
please feel free to move this post to the RAC section if you feel necessary.
Thank you.

I am trying to install itunes 10 but error messages saying could not update the environment variable PATH and CLASSPATH appear. how can i fix this?

this is really frustrating ive been googling for hours trying to find the solution! any help would be greatly appreciated. I have windows 7 and the newest gen ipod nano

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach.

Update environment variables of unix from java

i want to update DISPLAY environment variable in unix from java.
(very urgent).

Basically not possible. The environmental variables belong to a particular task, typically the shell, and your JVM process just has a copy. If you create another task (with Runtime.exec) you can specify whatever environmental variables you like but it's always the parent that supplies them to the child, not the other way arround. (export is handled internally by the shell's own task, it's not a program of it's own).

Using a environment variable that was created during the Task Sequence process - SCCM 2012 R2

Hi,
I'm triyng to use a environment variable that is create in the beginning of the Task Sequence.
1. I'm using a VBScript that get the Exit Code of an application, and create the environment variable "iReturn" with the value of the exit code. (This is working)
2. I add this variable in the CustomSettings.ini, like this "iReturn=%iReturn%
3. After the step that I run the VBScript I put the "Gather" step to get the variables, but looking in the BDD.log the iReturn variable appears the same as the CustomSettings.ini configuration "iReturn=%iReturn%". (But, if I put a "Restart
Computer" step after the VBScript, the BDD.log shows the iReturn variable with the right code.)
Question: How can I update the environment variable of Windonws XP to use in the Task Sequence without restart.
OR
How can I configure autologon in SCCM 2012 (if have no way to update withou restart computer).
I already tried the autologon with registry settings and a specific user, If I starts the process with this user works, but If I starts the process with other user, after the autologon the process doesnt continue, I have to do logoff and login with the user
that I started the process.
PS: All this steps have to be executed before the WinPE phase.

Environment variables must be explicitly set every time a system boots so unless you have a process to repopulate it after the reboot, it won't persist automatically.
Why not store the value in a task sequence variable so that it persists after a reboot?

Installed jre and jdk and setup environment variable

installed jre and jdk and setup environment variable but still i am not able to rum program?
cannot find symbol class string
package system does not exist

if removing 1 jre will help your disk space problems
then you urgently need a bigger disk.
Btw i never notice Java installing 2 different JRE's
so i dont think it will harm remvong one, make sure
you dont delete one you are using :)I assume that you don't run MS os; that's the only one that installs 2 JRE's.
To OP: This has been discussed by Sun, but no changes have been announced. Maybe the relocation in version 1.5 of the private (aka developer) code to the Program Folder is a start of this change?

How to get system Environment variable?

How to get system Environment variable without using jni?
just like "JAVA_HOME" or "PATH"...
Any reply is help to me!! :-)

Thx for your reply...
I get it!!!
Read environment variables from an application
Start the JVM with the "-D" switch to pass properties to the application and read them with the System.getProperty() method. SET myvar=Hello world
SET myothervar=nothing
java -Dmyvar="%myvar%" -Dmyothervar="%myothervar%" myClass
then in myClass String myvar = System.getProperty("myvar");
String myothervar = System.getProperty("myothervar");
This is useful when using a JAVA program as a CGI.
(DOS bat file acting as a CGI) java -DREQUEST_METHOD="%REQUEST_METHOD%"
-DQUERY_STRING="%QUERY_STRING%"
javaCGI
If you don't know in advance, the name of the variable to be passed to the JVM, then there is no 100% Java way to retrieve them.
NOTE: JDK1.5 provides a way to achieve this, see this HowTo.
One approach (not the easiest one), is to use a JNI call to fetch the variables, see this HowTo.
A more low-tech way, is to launch the appropriate call to the operating system and capture the output. The following snippet puts all environment variables in a Properties class and display the value the TEMP variable. import java.io.*;
import java.util.*;
public class ReadEnv {
public static Properties getEnvVars() throws Throwable {
Process p = null;
Properties envVars = new Properties();
Runtime r = Runtime.getRuntime();
String OS = System.getProperty("os.name").toLowerCase();
// System.out.println(OS);
if (OS.indexOf("windows 9") > -1) {
p = r.exec( "command.com /c set" );
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1 )
|| (OS.indexOf("windows xp") > -1) ) {
// thanks to JuanFran for the xp fix!
p = r.exec( "cmd.exe /c set" );
else {
// our last hope, we assume Unix (thanks to H. Ware for the fix)
p = r.exec( "env" );
BufferedReader br = new BufferedReader
( new InputStreamReader( p.getInputStream() ) );
String line;
while( (line = br.readLine()) != null ) {
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
String value = line.substring( idx+1 );
envVars.setProperty( key, value );
// System.out.println( key + " = " + value );
return envVars;
public static void main(String args[]) {
try {
Properties p = ReadEnv.getEnvVars();
System.out.println("the current value of TEMP is : " +
p.getProperty("TEMP"));
catch (Throwable e) {
e.printStackTrace();
Thanks to W.Rijnders for the W2K fix.
An update from Van Ly :
I found that, on Windows 2003 server, the property value for "os.name" is actually "windows 2003." So either that has to be added to the bunch of tests or just relax the comparison strings a bit: else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1 )
|| (OS.indexOf("windows 2003") > -1 ) // works but is quite specific to 2003
|| (OS.indexOf("windows xp") > -1) ) {
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 20") > -1 ) // probably is better since no other OS would return "windows" anyway
|| (OS.indexOf("windows xp") > -1) ) {
I started with "windows 200" but thought "what the hell" and made it "windows 20" to lengthen its longivity. You could push it further and use "windows 2," I suppose. The only thing to watch out for is to not overlap with "windows 9."
On Windows, pre-JDK 1.2 JVM has trouble reading the Output stream directly from the SET command, it never returns. Here 2 ways to bypass this behaviour.
First, instead of calling directly the SET command, we use a BAT file, after the SET command we print a known string. Then, in Java, when we read this known string, we exit from loop. [env.bat]
@set
@echo **end
[java]
if (OS.indexOf("windows") > -1) {
p = r.exec( "env.bat" );
while( (line = br.readLine()) != null ) {
if (line.indexOf("**end")>-1) break;
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
String value = line.substring( idx+1 );
hash.put( key, value );
System.out.println( key + " = " + value );
The other solution is to send the result of the SET command to file and then read the file from Java. ...
if (OS.indexOf("windows 9") > -1) {
p = r.exec( "command.com /c set > envvar.txt" );
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1
|| (OS.indexOf("windows xp") > -1) ) {
// thanks to JuanFran for the xp fix!
p = r.exec( "cmd.exe /c set > envvar.txt" );
// then read back the file
Properties p = new Properties();
p.load(new FileInputStream("envvar.txt"));
Thanks to JP Daviau
// UNIX
public Properties getEnvironment() throws java.io.IOException {
Properties env = new Properties();
env.load(Runtime.getRuntime().exec("env").getInputStream());
return env;
Properties env = getEnvironment();
String myEnvVar = env.get("MYENV_VAR");
To read only one variable : // NT version , adaptation for other OS is left as an exercise...
Process p = Runtime.getRuntime().exec("cmd.exe /c echo %MYVAR%");
BufferedReader br = new BufferedReader
( new InputStreamReader( p.getInputStream() ) );
String myvar = br.readLine();
System.out.println(myvar);
Java's System properties contains some useful informations about the environment, for example, the TEMP and PATH environment variables (on Windows). public class ShowSome {
public static void main(String args[]){
System.out.println("TEMP : " + System.getProperty("java.io.tmpdir"));
System.out.println("PATH : " + System.getProperty("java.library.path"));
System.out.println("CLASSPATH : " + System.getProperty("java.class.path"));
System.out.println("SYSTEM DIR : " +
System.getProperty("user.home")); // ex. c:\windows on Win9x system
System.out.println("CURRENT DIR: " + System.getProperty("user.dir"));
Here some tips from H. Ware about the PATH on different OS.
PATH is not quite the same as library path. In unixes, they are completely different---the libraries typically have their own directories. System.out.println("the current value of PATH is: {" +
p.getProperty("PATH")+"}");
System.out.println("LIBPATH: {" +
System.getProperty("java.library.path")+"}");
gives the current value of PATH is:
{/home/hware/bin:/usr/local/bin:/usr/xpg4/bin:/opt/SUNWspro/bin:/usr/ccs/bin:
/usr/ucb:/bin:/usr/bin:/home/hware/linux-bin:/usr/openwin/bin/:/usr/games/:

Using custom environment variables in the profile path

Hi,
I've created a custom environment variable that I've setup on two computers and the domain controllers. I want to use this in the profile path in user properties. However when users log in the variable is taken literally rather than being converted
into the value. For example
\\fileserver\share\user\%myenv%.v2 is generated rather than \\fileserver\share\user\envdata.v2
If I add in another built-in variable such as %OS%, that converts properly but any time I use a custom variable Windows just doesn't use it during the logon process. If I open up Explorer and type in the path to my data as it should be it works fine
so Windows is definitely picking up the variable, just not using during the logon process. I can't seem to find a TechNet article that states custom variables can't be used in profile paths.
Has anyone else come across this?
Thanks,
Tim

Hi,
Thanks for your post.
So did you create the environment variable using group policy? If yes, i would suggest you use 'Create' and not 'Update', the variable is then held through reboots.
Please refer to this blog, hope it will be helpful

Library paths and environment variables

Hello,
I am using 10g AS 9.0.4 on a Unix system.
I am trying to convert an old JSP web application to work with 10g. It is not an EAR/WAR file so I am manually trying to set it up under the "default-web-app" folder. It uses a number of java class files which currently reside in $J2EE_HOME/default-web-app/WEB-INF/classes/mystuff.
These class files require access to a number of libraries. I foolishly believed that they would be accessible if I were to place them in the $J2EE_HOME/default-web-app/WEB-INF/lib folder, but that did not work.
I read that OC4J uses a "catch all" lib directory at $J2EE_HOME/applib. I copied the library files there and they still did not work.
Frustrated, I tried to print out the environment variables for the server - only to find that this function is not supported.
I managed to print out the library path by creating a Java class files which returns the following as a string:
System.getProperty("java.library.path");
This (when called from a JSP) prints a number of different library paths, none of which match those found listed in the $J2EE_HOME/config/application.xml file. I placed the library files in one of the paths listed by the "java.library.path" and it worked!
3 questions:
1. How do you print the server's environment variables using a JSP? This strikes me as a very useful function for sorting out library and path issues. Do a search on Google for "print environment variables OC4J" or something similar and there are no useful pages suggesting how this can be done.
2. Why are the default library paths different on the server than to those specified in application.xml?
3. How do I change the LD_LIBRARY_PATH (or any environment variable for that matter)? I have tried adding the following line to $ORACLE_HOME/Apache/Jserv/etc/jserv.properties without success:
wrapper.env=LD_LIBRARY_PATH=/my/custom/library/path
Any help you can offer would be most appreciated.

>
Thanks very much for a such a comprehensive response
- it has helped answer a lot of questions, especially
being able to print out the system properties. That
will be really useful!
No worries at all Rob.
The main hurdle is that the libraries are indeed
native (*.so) libraries. I hadn't considered that
until you pointed it out in your message. Can I
assume, then, that $J2EE_HOME/applib and
$J2EE_HOME/default-web-app/WEB-INF/lib are only
designed to handle Java's .JAR librares? That would
explain why placing the native libraries in there
didn't work, but is there a way of getting such
native libraries recognised and bundled up in a
WAR/EAR file?
Yep, that's it.
Our proprietary applib and the servlet specs web-inf/lib are only dealing with Java archives.
The J2EE specs don't cover how to deal with native libs like this.
Now I've NEVER EVER tried it, but it's worth a shot of at least trying -- for simplified packaging purposes, what you may be able to do is to distribute the .so's within the web-inf/lib -- and then just set that directory (where's its realized on the server after the app is deployed) to be referenced witihn the LD_LIBRARY_PATH. I'd expect our deployment manager will just ignore files it doesn't know about, so arguably you should be able to at least distribute them with the standard archive.
You'll need to specifically set the LD_LIBRARY_PATH as a separate task outside of the deployment operation though.

This is where things get a bit weird, and is partly
my fault during the installation of 10g AS.
We already had an existing installation of Oracle 10g
Database (10.1.0) at $ORACLE_HOME under the user
"oracle". I logged in as the user "oracle" to install
the Application Server into a different location (In
this case, "$ORACLE_HOME/../ias10g_9.0.4" - let's
call this $IAS_HOME). So there is no separate user
account for Oracle Database and Application Server
(and hence no separate $LD_LIBRARY_PATH).
If I log into UNIX as the user "oracle" and echo the
LD_LIBRARY_PATH, I get the following directories:
$ORACLE_HOME/lib
/usr/openv/netbackup/bin
/usr/dt/lib
/usr/lib
I use this user to do "opmnctl stopall" and "opmnctl
startall". If I then print out the library path from
a JSP using
"System.getProperty("java.library.path");", I get the
following paths:
$IAS_HOME/jdk/jre/lib/sparc/server
$IAS_HOME/jdk/jre/lib/sparc
$IAS_HOME/jdk/jre/../lib/sparc
$IAS_HOME/opmn/lib
$IAS_HOME/lib
$IAS_HOME/usr/lib
Which is totally different to those listed by
$LD_LIBRARY_PATH at the command line, which means
they must be coming from somewhere else.
It gets worse - my application is trying to call a
native library that is only present in the
$ORACLE_HOME/lib32 directory (libclntsh.so.10.1), so
unless I can include this path in the
"java.library.path" on the Applicaiton Server, then
my program will not work.
So, how do I change the "java.library.path" when the
values aren't coming from $LD_LIBRARY_PATH in the
first place?
The utility $IAS_HOME/opmn/bin/opmnctl is actually a shell script.
It has this section which sets the LD_LIBRARY_PATH:
if [ -z "$LD_LIBRARY_PATH" ]
then
LD_LIBRARY_PATH=$ORACLE_HOME/opmn/lib:$ORACLE_HOME/lib ; export LD_LIBRARY_PATH
else LD_LIBRARY_PATH=$ORACLE_HOME/opmn/lib:$ORACLE_HOME/lib:${LD_LIBRARY_PATH} ; export LD_LIBRARY_PATH
fi
So if you have an existing LD_LIBRARY_PATH env var set, it should just be putting its paths onto the front of it.
What you could try as a quick test is to edit the opmnctl script (after taking a backup of course) and either appending the path you need to it, or just add some debug statements to output the LD_LIBRARY_PATH value it ends up setting so you can try and work out what's causing it.
I expect these other entries:
$IAS_HOME/jdk/jre/lib/sparc/server
$IAS_HOME/jdk/jre/lib/sparc
$IAS_HOME/jdk/jre/../lib/sparc
are coming from the JRE when it is launched, in probably a similar manner to our opmn entries.
I really appreciate your help, and I bet if anyone
can answer these questions, you can! ;-)
You're very welcome.
cheers

How do I use a OS (Windows) Environment Variable in the source path of me ActionScript 3.0 settings

I'm sure this can be done as I know we used something similiar at my old work place, below is an image showing what I am attempting to do.
We used this to create more portable / shareable assets files which when symbols are linking to code, the code was very often in different directories on different machines.
So we had set up environment variables in the OS to point to source directories and then used these variables in the source paths.
As long as everyone had these variables set up then it would all work.
Anyone know the correct way to do this in Flash CC
Thanks in advance!
Best Wishes
Rhys Thomas

sinious the problem with doing that is that the changed path gets into the code repository as well, so you wind up with everyone going back and forth changing it to their own value, which is a hassle. If you use relative paths and a standard project setup, then it all "just works" without a problem.
For example, this is the setup I use:
.dev
     .thisProject
          .Flash1
               Flash1.as
               .Flash1
                    Flash1.xfl
               .view
                    .audioAssets
                    .customViews
          .SoundLib
               SoundLib.xfl
          SoundLib.swc
     .bin <swfs are output here
          .xml
     .core
          .control
          .model
          .service
          .view
We have a "base project" that you check out to start a new project (we do heaps of similar work), and the paths are already set up to be relative. Having each project point to its own copy of the core code allows for fine-grained control of which revision you're using--we've even pointed deliberately to old versions or branches on rare occasions.
The bin folder is actually shared with the website repository, which is in a different directory from the Flash source code (in the website, it has a different name). This allows the generated swfs to be easily updated and ensures that the latest XML is being used both for development and on the site.
The "thisProject" folder actually includes a Flash Builder workspace with all the standard shortcuts, etc., already set up. This is primarily because of how the "default path" works when you create a new Flash Pro project in FB. Because we output a level up from the workspace, we hack the .metadata folder every time, but that's a small change.

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 to set the PATH Environment variable with multiple homes?

I have several Oracle homes, and now I cannot get reports to work anymore. These are the things I installed, in this order:
- Oracle Database 10g
- Oracle Developer Suite 10g
- Oracle Discoverer 4
- Oracle HTMLDB
Now my PATH environment variable is flooded with paths, but none seem to work when I want to start Reports 10g. I deleted all of the paths from the other homes and still no luck.
This was my original PATH:
C:\oracle\product\10.1.0\db_1\jre\1.4.2\bin\client;

What am I supposed to change to get Reports to work again (i.e. do more than just show the splash screen)?
Forms and Designer work just fine....

Never mind I found my solution here:

Problem with environment variable & compiling

G'day all,
I'm totally confused :(
I've set my environment detail but when I use javac the command window just does nothing. The cursor (or flashing thingo) drops to the line below and just hangs there. If i manually type in the entire path javac works fine.
Image of my environment variable window is here:

Using Windows 7, JDK 1.6.0_18 and latest version of Eclipse is installed.
Second issue:
I wrote a program using Eclipse. It all went into a package named "openagil". 3 classes in total. Class "A", "B", "C". A uses both B and C. It creates an instance of B and C. Included in each is package openagil; at the very top.
Running in eclipse it works fine. However, how do I compile this using javac and then in turn run it? The .java files are located within a workbench folder (java) and then in the package directory (openagil). These are contained on the D drive so "d:\java\openagil" - No class variables are set as I am unsure how this is done (despite reading a few guides).
I can do javac d:\...*.java and it'll compile all of them fine but I am then unsure how to run it. I think what I do is do java openagil.classA but this pulls up errors - an "exception in thread' error followed by a "noclassdeffound: openagil/classA" then a whole bunch of URL/Access Controller stuff.
I understand programming fine, but configuring this is a bitch. My Java book doesn't cover installation nor does it cover packages and the

I think it would be java -cp d:\java openagil.classAFYI class naming convention is to start with a capital letter - YourMainClass for example. It may help to go here [http://java.sun.com/javase/6/docs/technotes/tools/index.html] and go to General Information, then click on How Classes Are Found.

Help with setting environment variable on solaris 10

hi, i am new to solaris. i have solaris 10 x86, and as root user, i installed jdk 6 into /usr/jdk/jdk1.6.0_20. now i want to add the path /usr/jdk/jdk1.6.0_20/bin to my path variable. also i want to set JAVA_HOME. but each time i do this, and close the terminal, it resets. i mean when i echo $JAVA_HOME, i get nothing and if i echo $path, the address i aded is no longer there too.
what can i do to make this permanent. and do i have to set it for every user, or will the one set by root, be seen by all users?
thanks.

Assuming you're using tcsh, then I typically place my environment variables in my .login.
You can also place them in your .tcshrc file.
Use
setenv JAVA_HOME <path>
for tcsh.
For the Bourne shell, you can put them in the .profile file.
Use
JAVA_HOME=<path>
export JAVA_HOME
