Getting oracle environment variables using plsql code

Hi Geeks,
Can anyone tell me how to get an Oracle environment variable (eg db_cache_size) from inside a plsql block of code or through a sql query?
Thanks,
Prabhu

Is it possible to update the values via SQL?That's indicated by:
ISSES_MODIFIABLE VARCHAR2(5) Indicates whether the parameter can be changed with ALTER SESSION (TRUE) or not (FALSE)
ISSYS_MODIFIABLE VARCHAR2(9) Indicates whether the parameter can be changed with ALTER SYSTEM and when the change takes effect:

Setting Oracle environment variable using batch (.bat) file in windows

Hi,
Oracle 9i db
Windows OS
I am in process to create the database (Considered that Oracle9i software is already installed) by running one batch file which consist of all the scripts for the database creation.
But i also want to set the environment variables at MyComputer(right click)>properties>advance>environment, permenently by running the batch (.bat) file
ORACLE_HOME
ORACLE_BASE
ORACLE_SID
So, how can it be done ?
With Regards

Hi,
*@echo off*
set ORACLE_SID=iprsdb
set ORACLE_BASE=C:\oracle
set ORACLE_HOME=C:\oracle\ora92
call C:\install_bkp\test_env_var.bat
echo Test Successfull.
Above mentioned is the code written in the batch (.bat) file
In that i have also called another .bat file which test the env. variable values which is as below:
c:\>test_env.bat
===================
Testing oracle sid
===================
iprsdb
=====================
Testing oracle base
===================
C:\oracle
=====================
Testing oracle home
=====================
C:\oracle\ora92
Test Successfull.
But when i checked at MyComputer(right click)>properties>advance>environment variables
there, I saw none of the entries from the above, why so ?
how to set env. variables permanently using the DOS commands. ?

How to read a non-oracle environment variable?

I have been trying to read a non-oracle environment variable using TOOL_ENV.GETVAR, and have come to understand that it doesn't work. Is there another function that can do what I want? I don't want to hardcode the directory the forms and reports must reside in, but can't find anyway to make this value flexible.
can anyone help ?
thx
adam

I figured out a way. I put a String in the registry in the oracle home area, and can read it with TOOL_ENV.GETVAR now. It appears that it reads from the registry, not the environment variables. Except for unix apparently, where it reads environment variables.

Unable to access value in System Environment Variable using Java

I am using Java code to get the value of a System Environment Variable using the Runtime, Process java classes.
The code works fine in tomcat, but when deployed in 9ias the code is unable to retrieve the value stored in the System environment variable in Windows 2000.

Thanks for the comment steve, here is the code which i am using.

Oracle Environment Variable Problem - OCIEnvNlsCreate() failed

We are using PHP 5.2.3 with oci8 version 1.2.3 in CentOS 5.0.
We have installed Oracle 10g in the same machine where Apache (2.2.3) is running.
First we tried to set the Oracle environment variable in httpd.conf as
SetEnv ORACLE_HOME u01/app/..../db_1
SetEnv ORACLE_SID oratest.
But we were unable to connect and got the message 'OCIEnvNlsCreate() failed'.
Then we tried to set the environment variables in root's bash profile.
Then it did work in PHP command line interface. But it didn't work in browser. Interestingly, getenv function shows the environment variables correctly (even in the browser).
We also given the read and execute permissions for all users in all directories of oracle. But still it gives the same error.
Please help.

While trying to get new oci8 php extension to work I remember trying to set parameters using SetEnv inside apache httpd.conf or inside .htaccess file. However this is not recommended and I remember seeing some suggestions as not to use SetEnv for Oracle environment variables. I also had issues with that before. I went and added bash
export ORACLE_HOME=... to the Apache startup script in /etc/init.d and this has resolved the problem for me.
I hope this helps.

How to get an environment variable from OS in class ?

Hello,
How to get an environment variable from OS in class ?
Thanks !

An example of a Java application that does this is Ant, when you add a line like this in your build.xml:

<property environment="env"/>
I have looked at the source code of Ant 1.3, especially the file src/main/org/apache/tools/ant/taskdefs/Execute.java. Look at the methods getProcEnvironment() and getProcEnvCommand(). Ant uses an OS-dependent trick to get the environment variables.
You can download the Ant source code from http://jakarta.apache.org/ant

Oracle environment variable setting for mulit instances

Dear experts,
I am doing CRM_ABAP, CRM_JAVA,ERP installation based on Oracle in a laptop for SAP Best Practise.
The CRM_ABAP installation have done, and start to install CRM_JAVA named CRJ.
In CRM_ABAP installation, I set Oracle environment variable as below:(/etc/profile.d/oracle.sh)
・CRACLE_SID=u201DCRMu201D
・CRACLE_HOME=u201Doracle/CRMu201D
・PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/bin/oPatch:$PATH:
・export CRACLE_SID CRACLE_HOME PATH
My question is that how do I set environment variable for CRM_JAVA(CRJ) in oracle.sh,?
I tried e.g. CRACLE_SID=u201DCRMu201D:u201DCRJu201D, CRACLE_HOME=u201Doracle/CRMu201D:u201Doracle/CRJ/102_64u201D
or CRACLE_SID=u201DCRJu201D CRACLE_HOME=oracle/CRJ/102_64u201D export CRACLE_SID CRACLE_HOME
in addition
but got an error message in SAPinst (Task Progress: configure Oracle server network)
said u201CAssertion failed:lsnrctl:Parameter dbHOME has to be a valid ORACLE_HOME).u201D
kindly help me to reslove the issue.
Thanks.
regards.

Setting a Linux environment variable like ORACLE_SID to multiple values will not work.
Use another oracle.sh, and maybe also another Linux user.
I am not familiar with the details, but what does your installation guide say?
Or you may have to use the same values for Java. The installation guide will tell you.

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/:

Is there any way to get windows environment variables like %USERNAME% with javascript?

is there any way to get windows environment variables like %USERNAME% with javascript using Adobe 10 pro?

There is a fair amount of Acrobat JavaScript and Acrobat knowledge need to sort all of this out.
The identity object holds a lot of sedative information. First, upon installation of Acrobat, only the login name is available in the identity object and the end user of the application needs to complete the "Name", "email" and "Organization Name" in the application's preferences. These are the only fields that are available to Acrobat JavaScript identity object as corporation, email, loginName, and name.
Using the instructions in The Acrobat JavaScript Console (Your best friend for developing Acrobat JavaScript) you can run the following script in the JS console to see the items of the identity object:
for(i in identity) {
console.println(i +": " + identity[i]);
and the following will appear in the console:
loginName: georgeK
name: George Kaiser
corporation: Example
email: [email protected]
true
The documentation states you need to use a trusted function to access this data, but you can access it at startup of Acrobat/Reader and add the properties of the identity object to an array:
// application variable to hold the properties of the identity object
var MyIdentity = new Array();
// loop through the properties of the identity object
for (i in identity) {
// place each property of the identity object into an element of the same name in the Identity array
MyIdentity[i] = identity[i];
console.println(i +": " + MyIdentity[i])
You access the items with:
var loginUser = MyIdentity[loginName]; // get the loginName property
In the user application level JavaScript file. See Acrobat Help / User JavaScript Changes for 10.1.1 (Acrobat | Reader) for the location of the application level folder you need to use.
I would change the name of the array used in this post so an untrusted user cannot get to your data. Some of this data can be used in hacking into a user's system.

The solution I proposed worked only on Windows XP/2003.
The following solution will work on Windows NT/2000/XP/2003 with JDK 1.2+.
1- Download the [url http://www.gjt.org/download/time/java/jnireg/registry-3.1.3.zip]JNIRegistry zipped archive.
2- Open the registry-3.1.3.zip file and extract in the folder of your choice ( Eg. c:\setenv ) only the 2 first files (when sorted by path): ICE_JNIRegistry.dll and registry.jar.
You don't need to keep the folder tree in the extraction.
3- Create the following SetEnv.java file in the same folder ( Eg. c:\setenv ).
import com.ice.jni.registry.Registry;
import com.ice.jni.registry.RegistryKey;
import com.ice.jni.registry.RegStringValue;
import com.ice.jni.registry.RegistryValue;
public class SetEnv
    static final String REG_HKLM_SUBKEY_NAME = "SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment";
    public static void main(String[] args)
    throws Exception
        new SetEnv().exec(args);
    void exec(String[] args)
    throws Exception
        if (args.length != 2)
            throw new IllegalArgumentException("\n\nUsage: java SetEnv {varName} {varValue}\n\n");
        String varName = args[0];
        String varValue = args[1];
        RegistryKey key = null;
        RegStringValue value;
        try
            key = Registry.HKEY_LOCAL_MACHINE.openSubKey(REG_HKLM_SUBKEY_NAME, RegistryKey.ACCESS_ALL);
            value = new RegStringValue(key, varName, RegistryValue.REG_EXPAND_SZ);
            value.setData(varValue);
            key.setValue(value);
            key.flushKey();
        finally
            try { key.closeKey(); }
            catch (Exception e) {}
}4- Compile it.
javac -classpath .;registry.jar SetEnv.java
5- Run it. varName and varValue are strings of your choice.
java -classpath .;registry.jar -Djava.library.path=. SetEnv varName varValue

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,
Zoran

Do 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
Patrick

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.

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

Oracle environment variable tns_admin instead tnsnames.ora

Hi, I have a big trouble with the tns_name file. First of all I am working oracle with visual studio .net. I have the file tns_name in the following route C:\oracle\ora92\network\ADMIN\tnsnames.ora. If I delete this file, visual studio .net can still work properly. Then I figured out that it is taking the tnsnames from tns_admin in environment variables. It means visual studio .net is taking the tnsnames from tns_admin instead of C:\oracle\ora92\network\ADMIN\tnsnames.ora.
Can someone explain me why and how is the way to configure which file is used? Where can I configure it?
Thanks in advance.

it throws the following error: ora-12154 tns could not resolveORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

How do you get your environment variables seen in SS?

I am trying out SS, we currently use gcc/Kdevelop. When I try to launch my program or debug inside Sun Studio I get an error about a missing .so. Since everything works fine from the command line I assume SS does see my shell environment variables. I don't see any option for this, what am I missing?

First of all, you can check whether environment is inherited or not from dbx command line:
- start debug session
- go to "Dbx console" tab at the bottom
- issue 'set' command and/or 'set | grep your_variable' to see if it is there
If it's really missing or has value other that expected, use project properties to specify environment for the application. It can be done like this:
- right-click project in Projects window, choose Properties
- select "Running" node
- and edit the "Environment" field
