Retrieve OS Environment variable values
Dear All,
In all Operating System we can set the system environment variables in either Batch file(Windows) or script files (Unix Based operating system). Is there any way to retrive the variable values declared in the batch file or script file in throu java application without specifying -D param in java command
Thanks
ARvind
Personally, I use a little dirty trick to get the environment settings on Windows.
I have a batch file doing "set > output.txt". Then I call this batch file with Runtime.exec() and I parse the resulting output.txt file.
Not clean at all, but it works ;-)

I am not getting User Environment Variable Value

I show you data result after procedure was excecuted.

I see that only ORACLE_HOME variable value was got, question is why, of course, variable values are already defined as user variables.
Variables PATH_MODULO and FILELOG was defined using windows maintenance variable method, that is :
1.- settings
2.- system
3.- advanced options
4.- environment variables
Here my oracle version
SQL> select version from v$instance;
VERSION
10.2.0.1.0
SQL>
Is this an Oracle Issue or variables would be defined in another way?
ORACLE_HOME VARIABLE was created when oracle engine was installed.
I have got same result after computer was restart.
I appreciate wathever clue.Ok, that is , I only can read environment variables values, but not variables values at user profile. It happends in unix environment too. So I tried to use another instruction sequence in order to read user variables values.

Hi all,
how do i get the environment variables in PL/SQL on Windows NT/2000 or SUN environment..?
Thanks.hi Andrew P Clarke ,
Thanks for ur immediate reply. That's fine, using sys_context. But i'm not asking thatt...sorrry i didn't specified clearly.
My question is how do i get the Operating system - User defined system variables. (Ex: in Win 2000 Server Box i've creadted the sysvariable like TEST='C:\TEST\FILE\', like our V$parameter in ORACLE...in 'C'/JAVA we will use the function "GETENV".
Similllar one in oracle. how do i get the value?
Thank You very much for ur help and OTN. -
How to get the path of the INST_TOP environment variable value
Hi,
I have some file processing code in the OAF. I would like to use INST_TOP/temp folder as a temporary location. When I tried to get the env variable from System.getenv(), System.getProperties(), they don't seem to have INST_TOP in the list.
Could anyone please tell me if it could be fetched from some other place ?
Thanks
PonrajConcurrent processes store the value in fnd_env_context ... if that helps, you might do something like the following (example only for this thread, not tested!):
select value from FND_ENV_CONTEXT where variable_name = 'INST_TOP' and concurrent_process_id = (select max(concurrent_process_id) from FND_ENV_CONTEXT);

CLASSPATH Environment Variable on Win2k problem
hi
i am new to java, but having problems to seting the CLASSPATH Environment Variable on my Win2k professional. my university computers are alredy set and i enjoy working with java. i just cant get my head arround to this problem. it would be much appriciated if some one send me a link which provide screenshot to resolve this problem. i got my jdk1.4 kit in a folder caled jdk in c:\ root.

Our application is stand-alone application and we are using Applet with Object Id tag for JavaScript to Java connectivity. In our application we are displaying the value of classpath environment variable on screen.
Applets and stand alone applications are two different animals.
While migrating from JRE 1.5 to JRE 1.6, we are unable to retrieve the classpath variable value. After analyzing, figure out that when classpath is defined in uppercase (i.e. CLASSPATH) then only we are unable to retrieve its value. However if its defined in lower case or any character is in lower case (i.e. classpath) then its value appears correctly. We are retrieving the classpath value via the "Set" command from Java.
That's completely unnecessary, there's a System.getevn("CLASSPATH") method.
However the CLASSPATH environmental variable isn't much use, and certainly not in the case of Applets, which definitely don't use it.
Futhermore I don't expect the sandbox environment of an Applet will allow you to access the environmental variables in any way, (certainly not by running a program). Applets, unless signed, have almost no access to the client machine they run on. -
Hi everybody
I'm trying to read an environment variable value, but I don't know how to do it.
Thanks.Five possibilities:
-Don't use a env var for application values. Use a java property file instead.
-Use System.getenv() on versions before 1.3.
-Use the java command line option '-D' which makes the passed in value available via the system properties.
-Use Runtime.exec() to run a OS specific command that returns the value and parse it.
-Use JNI. -
Using CIS to get UCM environment variables
Hi,
I am working on extending an existing CIS application.
I would need to read the UCM's environment variable value.
I see there are CIS APIs for the most common actions needed, but couldn't find anything useful in the docs - is there something similar for the env variables?
Any help is highly appreciated.
Thanks,
ZoranDo you want to get the port and server name from the web server or from the database?
If it's the web server have a look at the package OWA_Util.print_cgi_env to get a list (you can also run this procedure in the SQL Workshop) of all available environment variables in the HTTP session context. Use OWA_Util.get_env to read the value of a particular environment variable.
Hope that helps

Hey,
I am trying to use
cl_gui_frontend_services=>gui_download
and include the windows environment variable %USERPROFILE%
in the path for example:
filename = '%USERPROFILE%/filename.txt'
that only creates a directory called %USERPROFILE% but not the Variable.
Has anybody experienced this ?
Thank your for your help,
kind Regards
Christofyou have to use the following code to get the environment variable value and then use that with gui_download
call method cl_gui_frontend_services=>environment_get_variable
exporting
variable = p_envir_name
changing
value = ls_envir_path
exceptions
cntl_error = 1
error_no_gui = 2
others = 3.
call method cl_gui_cfw=>flush
exceptions
cntl_system_error = 1
cntl_error = 2
others = 3. -
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/DEVAre 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. -

Retrieve environment variables (but not classpath or other java ones..)
Hi,
Does somebody know another way than System.getPropriety() to retrieve a environment (system) variable? I have a variable so-called CSServer designing a path, and I do not succeed to retrieve it from a Java program.
Any ideas?
Thanks
RichieI once implemented it by creating a process that executedecho %<yourVar>%and reading the output, but I'm not very proud of it.
For other options, search the forums.

Getting a Unix environment variable
Hi, everyone.
I need to use a Unix enviroment variable from a form. This form
is gonna use this variable in order to be the path of another
form who is gonna be called.
In other words:
CALL_FORM( $unix_var + '/forms/myform_name' );
unix_var is what I want to get.
Thanks a lot in advance,
EduardoIt worked, Michael. Thanks a lot!
To the documentation guys at Oracle... This is how you define
the TOOL_ENV package in the Forms' help:
"The TOOL_ENV package allows you to interact with Oracle
environment variables by retrieving their values for use in
subprograms."
Suggestion: ...with Oracle environment variables AND OTHER
SYSTEM OPERATION ENVIRONMENT VARIABLES...
because this narrow definition can prevent people for trying to
use it to retrieve other NON-ORACLE environment variable via
this package. Thanks.
