Adding environment variables to Runtime.exec()

Hello,
I'm trying to use Runtime.getRuntime().exec(command, envp);
When envp is null the program launches properly. (the doc says that the subprocess inherits the environment settings of the current process).
I want to add an environment variable, so when I use an array containing only my variable (envp), the process fails. I guess it needs the variables of the current process (as used when using null).
In that case, How adding a variable instead of replacing the default ??????
(I did not see any way to retrieve these default variables so I can concatenate with the custom one)
Thanks !

Use a wrapper script that is launched with a default environment and first sets the custom variable and goes on with your program.

Adding environment variable in build.xml(ANT)

Hi,
I need some information Regarding ANT,
the problem is i have to add a property file in build.xml (as a environment varialble) so that i can read it in my java code. as
System.getProperty("").
Please sugggest me how to set environment variable in build.xml(ANT)
Thanks

Hi Jakain, yep thanks for your information but my manager wants that way to do..
he wanted me to set property file as a environment file using build.xml as this property file changes dynamically..
can you suggest me

X11 environment variables on MacBook Pro

Hi
I have just got my new MacBook Pro and have installed Gimp to run using x11 that came on the apple installation disks however I can't seem to get the xterm to configure correctly.
GIMP is installed under /sw/bin but the default PATH for x11 does not include this location so I added PATH=$PATH:/sw/bin:/sw/sbin to a newly created .bash_profile. But x11 did not seem to use this file although terminal worked OK.
After doing a bit of research, I then created a .bashrc file with the PATH defined and changed the .bash_profile to source .bashrc with no other entries.
Again this worked OK for Terminal but now when I type 'echo $Path' in an x11 xterm the PATH displays two entries for /sw/bin & /sw/sbin. i.e.
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/sw/bin:/sw/sbin:/sw/bin:/sw/sbin
Any ideas why? and how can I correct it?
Macbook Pro 17 Mac OS X (10.4.9)

Sorry this was a bit brief; I think I was still asleep when I typed it.
The reasons are these:
1. Many fink programs require environment variables and other settings. When you source that init.sh file, it ensures everything is set up to work out of the box. (Among the things it does is to in turn source every relevant file in /sw/etc/profile.d -- take a look in it to see what, if anything, is in there). There is also some code to keep your path trimmed properly, so you don't get repeats pasted on.
2. Bash is unique in that either .bashrc or .bash_profile, but not both, get sourced. In a rooted X11 environment, everything works properly, but on OS X, where X11 is "rootless," it leads to unexpected behavior like what you saw. As long as you put everything into one file and then tell the other one to source its contents, you should be ok.
You can also run X11 stuff from Apple's terminal, provided you somewhere in a startup file have something to set the DISPLAY variable, usually to .0.
I've put more discussion of these things here

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/:

Environment variable setting not working in the report

Hi everybody,
Iam facing a problem related to reports10g ids. database is 9i
My basic requirement is ,i want to show a report out put in a BRAZILIAN PORTUGUESE Language.
For this purpose i configured the report_server.conf file like
<environment id="PS">
<envVariable name="NLS_LANG" value="BRAZILIAN PORTUGUESE_BRAZIL.WE8MSWIN1252"/>
</environment>
After that i added a entry along with the web.show_documents(using for calling the report)envid=PS
when iam running the report ,report server is only converting one date field in to portuguese ,rest of them are same as in the database.
Actualy i dont know where i did wrong.if anybody know please help meee
Thanks in advance
mathew

Hello Matthew,
See Note:231051.1, Dynamic Environment Switching In Reports 9i for an example of setting your environment variables at runtime. It uses REPORTS_PATH, there is also an entry for NLS_LANG in the reports.sh file (in UNIX). This setting is causing the conflict when you try to set it at runtime.
I think you have to remove the entry from reports.sh config file and then you will have to pass the parm at runtime everytime.
I hope this helps!

How do I clear environment variables in 10.6

I am having some difficulty in configuring custom paths with my environment variable, environment.plist. In setting up some of my software, I am trying to configure custom paths so that I can eventually store preferences on the server for all users to access the same tools. I had this working up until last week, when I installed a second piece of software, that modified my environment.plist file, which now doesn't work at all.
My original environment.plist file, which is located in ~/MacOSX, was as follows:
<plist version="1.0">
<dict>
    <key>NUKE_PATH</key>
    <string>/Users/jamesdavidson/Documents/Nuke_Gizmos/Nuke</string>
    <key>OFX_PLUGIN_PATH</key>
    <string>/Users/jamesdavidson/Documents/Nuke_Gizmos/OFX</string>
</dict>
</plist>
Which worked just fine. It was then changed to:
<plist version="1.0">
<dict>
    <key>NUKE_PATH</key>
    <string>/Users/jamesdavidson/Documents/Nuke_Gizmos/Nuke</string>
    <key>OFX_PLUGIN_PATH</key>
    <string>/Users/jamesdavidson/Documents/Nuke_Gizmos/OFX</string>
    <key>PATH</key>
    <string>/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/Applications/Deadline/Resou rces/bin</string>
</dict>
</plist>
and now, the only variable that shows up is PATH. I edited the file back to the original, without the PATH variable, restarted my machine, and yet my Variables did not change... Is there somewhere else that I should be looking? Some other file?   this is what I get from terminal:
$ echo $NUKE_PATH
$ echo $OFX_PLUGIN_PATH
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Applications/Deadline /Resources/bin
And this even after deleting my environment.plist file. Any help would be appreciated.
Thanks,
James

I hope you made a typo in your post and meant ~/.MacOSX. You typed ~/MacOSX, i.e., without the leading dot.
At any rate $PATH is a predefined shell variable so I suspect you cannot define that one with this environment.plist mechanism. The "proper" way to set up such things is with a ~/.bash_profile, ~/.bash_login, ~/.profile, or IMO, best of all. ~/.bashrc. These are scripts the shell looks for during launch (somewhat depending on whether it's a login shell or not -- see the bash reference manual).
If bash is executed interactively it will also first look for /etc/profile. And it will cause a $PATH variable to be created. So that is probably the definition you are seeing all the time until you create an appropriate startup script of your own (e.g., ~/.bashrc) to override or modifiy the existing $PATH variable.
Note, I may have paraphrased a lttile too much so see section 6.2 Bash Startup Files in the bash reference documentation for the complete proper description of the order these files are used. If you have the developer tools installed look for bashref.html. Otherwise it's online here.
Finally, if you look at /etc/profile you will see it attempting to execute /usr/libexec/path_helper -s. Try that in terminal and see if that isn't the $PATH definition you are currently seeing.

Not able to get SSL related CGI Environment Variables?

We are currently using APEX 3.2.0.x, OHS 10.1.3.x, and 11gR1 on linux. The APEX application we've been developing will be accessed via SSL and x509 certificates such that a client certificate is passed from a user's browser to the OHS, the information will be read from the certificate, and if the user's cert information exists in a user table associated with the application, they will have the role they've been assigned as an existing user within the application. Otherwise, the user will be a guest and have a minimum role accessing the application.
We are certainly not guru's when it has come to setting up and configuring SSL and certs, but we have gotten to the point where we have all of the required certs created and installed, and the client cert passes it's information successfully to the OHS to get to the "home" page of the application via the Rewrite statement in the httpd.conf/ssl.conf that points to the appropriate https url. We are now at the point where we need the APEX application page to read the cert information, and this is where we are having problems.
We have created an "On Load - Before Header" process and temporary item on the "home" page to display CGI environment variables to see what we're getting. It's a PLSQL Anonymous block like this:
DECLARE
lUserName VARCHAR2(100);
BEGIN
SELECT NVL(owa_util.get_cgi_env('REMOTE_USER'),'NOT POPULATED') INTO lUserName FROM DUAL;
:P1_REMOTE_USERNAME := lUserName;
END;
We can grab any of the cgi environment variables that are listed in the OHS mod_plsql User's Guide. We cannot seem to be able to get any of the SSL CGI environment variables though. We are adding the SSL variables to the dads.conf via the PlsqlCGIEnvironmentList parameter (ex: PlsqlCGIEnvironmentList SSL_CLIENT_S_DN_CN) and bouncing the OHS as needed. Unfortunately, we have not been successful in getting any of them to show up in the item on the APEX page.
As far as we can tell, we have the SSL/OHS/Certs configured, but may be there is another SSL directive or some other configuration item that we've missed that needs to be set in order for SSL CGI environment variables to be available to the owa_util.get_cgi_env function. If anyone can tell us what we may have missed, it would be appreciated.
thanks
bob

Hey John,
what we have found that we were not sure of is that we need to use Rewrite rules and conditions in the ssl.conf to grab the ssl cgi environment variables and "put" them into the request header to hold them like this:
RewriteCond %{SSL:SSL_SERVER_S_DN} (.*)
RewriteRule .* - [E=SSLS_DN:%1]
RequestHeader add X-SSL-SERVER-S-DN %{SSLS_DN}e
Then in the dads.conf put the request header reference in there with the plsqlcgienvironmentlist parameter like this:
PlsqlCGIEnvironmentList HTTP_X_SSL_SERVER_S_DN
Restart the OHS, and then grab the HTTP_X_SSL_SERVER_S_DN variable(s) via the owa_util.get_cgi_env in the APEX page to pull the value out with an anonymous block in an On Load - Before Header process like this:
DECLARE
lUserName VARCHAR2(100);
BEGIN
SELECT NVL(owa_util.get_cgi_env('HTTP_X_SSL_SERVER_S_DN'),'NOTHING HERE') INTO lUserName FROM DUAL;
END;
It's the Rewrite rules and putting them into the request header that we were not totally sure about as far as how and where you put the environment variables to make them accessible to the dads.conf with the PlsqlCGIEnvironmentList parameter that in turn makes them accessible to APEX. We're still not 100% sure this is the correct method, but it's working. We don't recall reading in any of the APEX docs, APEX forum threads, or other documentation about needing Rewrite rules and conditions to put the cgi environment variables into the request header to make them accessible to APEX. So, that seems to be our missing piece of the puzzle here.
Anyway, I think we're okay for the moment, and may be this thread will help someone else out in the future. Thanks for your help John, and will give you a helpful plug on the forum for this thread. BTW, I do have your book, so it was nice to see someone as advanced with APEX as yourself reply to the posting.
Thanks
Bob

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 to export an environment variable from command line ?

Hello,
I have build a python application which run some processes(or executable or other python scripts) using subprocess.
i.e.
subprocess.call(["xyz.py"], shell=True, stdout=log_file, stderr=log_file)
Above call throws an error as "xyz.py is not recognized as an internal or external command." I added the location of xyz.py into path variable inside a batch script which I used to run before running the script.
set PATH=D:\path of xyz:%PATH%
But As subprocess executes a script into anther child shell, This setting is not available in child shell (or sub-shell) used by python script.
How can I make this PATH setting available to sub-shell also ?

Rather than going into much details I have used explicit path by referring only one environment variable of the shell where application is running.
i.e. As xyz.py will be in a specific location of my repository, I am setting path of root_dir:
      set root_dir=<path_of_root_dir>
      And then,
      subprocess.call([os.path.join(os.environ['roo_dir'], 'dir', 'xyz.py')], ...)

Hello Matthew,
See Note:231051.1, Dynamic Environment Switching In Reports 9i for an example of setting your environment variables at runtime. It uses REPORTS_PATH, there is also an entry for NLS_LANG in the reports.sh file (in UNIX). This setting is causing the conflict when you try to set it at runtime.
I think you have to remove the entry from reports.sh config file and then you will have to pass the parm at runtime everytime.
I hope this helps!

How to include Windows environment variables in e-mail action scheduled task

Hello Support,
Is it possible to include Windows environment variables such as %username% or %computername% in the subject line or body of the "Send e-mail" action item of the Task Scheduler? For example, I would like when I setup a scheduled
task to perform a certain task and send an e-mail message, the email should include either the user name or computer name in the subject line and body of the e-mail. Is that possible?
Thanks

Hi,
You can create a new Scheduled Task preference item to solve your requirement.

I created a scheduled task and that does not provide what I need. The scheduled task will simple send an mail, but I want to know from which machine or user triggered the email. I also tried adding the batch file to the scheduled
task and that did not work even though the scheduled task has the following settings.
User Configuration >> Prefence >> Control Panel Settings >> Scheduled Tasks
When running the task, use the following user account
NT AUTHORITY\System
Run whether user is logged on or not
Run with highest privileges HighestAvailable
Configure for: Windows 7
I also tried with Computer Configurations

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.

Environment Variables don't work after migrating zcm policy

Hi There...
I hope anyone can help me with this.
After migrating my zcm policies to active directory I found my Environment Variables set in my login script do not work anymore.
My guess is that somehow the Environment Variables in the login script are in a different cmd environment then the zcm bundles. but I'm still in the dark what migrating the policies to a different environment has to do with this... and how to solve it.
The policies didn't change, just the environment from where they are loaded...
I build a workaround by adding the set commands within launch command of the bundle, but I would rather keep them in my login script instead of builing 3 or 4 icons of the same application but with different set Environment Variables.
If anyone has a good idea... let me know plz!!
TIA
Rey

ZCM does not detect changes in environment variables until a reboot.
It's possible the variables were being set earlier in the logon process
which proceeded ZCM fully initializing.
Consider using something such as SETX.exe or SETENV.exe which can set
them permanently. There will still be a one logon delay until they are
seen.

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.
