Hi Teches
I am facing few problem in starting eclipse 3.0 ; I had gone trogh forum , 1 of the persone suggest me to upgrade the java version.For this
I had installed java 1.5 and set the following variable
JAVA_HOME ---> to the home dir of JAVA
PATH ---><home dir>/bin
CLASSPATH --><jre>/lib
But when ever i m giving "java -version" command on console , the result is as follows:
C:\>java -version
java version "1.3.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)
suggestion are welcome Plz.

For a given process ID, how do I determine environment variables (e.g. PATH)?

At command line, what is the best/most direct way to determine the environment variables (e.g. PATH) for a given process ID? Must be able to query for any arbitrary environment variable. PATH is just the first example.
'lsof -a -p $PID -d cwd -F' gets some of it.
But, I don't see a way to get the PATH for the given PID, using lsof.
'ps -Ep $PID' gets some of it.
But, again, 'not comprehensive. It appears to give back only a portion of the 'environment' for the process.
On a number of other Linux/UNIX variants, you can look at '/proc/<pid>/environ'. But, OS X apparently does not use that mechanism.

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.

Setting widows environment variable like "path "

I want to set a new value for windows environment variable path. Is there any way to set change the varibale.

You could also use ORA_FFI package to call Windows API function SetEnvironmentVariable. There is an example below.

res:=WIN32.SetEnvironmentVariable( 'PATH', s );

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

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.

Does eTester has anything like environment variables like we have in QTP?

I need help in finding out the path where my test is saved.
For eg. - In QTP, I can use environment(TestDir). This will return the complete path where my test was stored. Similarly, how do i find this path in eTester.

I suppose you could use vbscript to scrape the caption of the OFT main window. That would give you the script name and workspace. The workspace will always fall under the the mapped file location (either local install directory or shared directory that is specified in the rsw.ini file) so all the information is there if you want to write your own vbscript

Open module for managing property file and environment variables

Looking for an open module for managing property files and environment variables (like CLASSPATH) set in a shell script. For handeling properties (preserving comments, supporting includes, appending new entries, and more) I have looked at SuperProperties from openadaptor but find certain functionality lacking. As for interfacing with common shell scripts/files containing setting for CLASSPATH, JAVA_HOME, other system/application variables another type of object editor is needed. Maybe JFIG?
Any ideas are greatly welcomed.

You seem wright, you hit a brick wall here with Air to find the location
of the command console on windows...
So in fact I never build an exe tool, but this little problem was a nice
case to test it and I tried it.:
I downloaded monodevelop
-GTK# for .NET 2.12.10*
-MonoDevelop 2.4.2*
from http://monodevelop.com/Download
created a console project and had an exe in 5 minutes !
You can download the findconsole tool and the projectfiles here:
http://greencollective.nl/temp/dump/findconsole_monoproject.zip
findconsole.exe will reveal the path/location of cmd.exe on a windows system.

Unix shell: Environment variable works for file system but not for ASM path

We would like to switch from file system to ASM for data files of Oracle tablespaces. For the path of the data files, we have so far used environment variables, e.g.,
CREATE TABLESPACE BMA DATAFILE '${ORACLE_DB_DATA}/bma.dbf' SIZE 2M AUTOEXTEND ON;
This works just fine (from shell scripts, PL/SQL packages, etc.) if ORACLE_DB_DATA denotes a file system path, such as "/home/oracle", but doesn’t work if the environment variable denotes an ASM path like "\+DATA/rac/datafile". I assume that it has something to do with "+" being a special character in the shell. However, escaping "\+" didn’t work. I tried with both bash and ksh.
Oracle managed files (e.g., set DB_CREATE_FILE_DEST to +DATA/rac/datafile) would be an option. However, this would require changing quite a few scripts and programs. Therefore, I am looking for a solution with the environment variable. Any suggestions?
The example below is on a RAC Attack system (http://en.wikibooks.org/wiki/RAC_Attack_-OracleCluster_Database_at_Home). I get the same issues on Solaris/AIX/HP-UX on 11.2.0.3 also.
Thanks,

My revised understanding is that it is not a shell issue with replacing +, but an Oracle problem. It appears that Oracle first checks whether the path starts with a "+" or not. If it does not (file system), it performs the normal environment variable resolution. If it does start with a "+" (ASM case), Oracle does not perform environment variable resolution. Escaping, such as "\+" instead of "+" doesn't work either.
To be more specific regarding my use case: I need the substitution to work from SQL*Plus scripts started with @script, PL/SQL packages with execute immediate, and optionally entered interactively in SQL*Plus.
Thanks,
Martin

Java classpath with Environment variable..

Hi,
I need to start an Java application with an Environment variable(EV) as class path.
Ex:
I have an EV APP_PATH =c:\myapp
so i will give java -cp c:\myapp, instead of doing like this I need to give APP_PATH in the java -cp<EV>.
I gave like this java -cp %APP_PATH% and that doesn't work...
Is this the correct way or how to do this ?
Thanks.

I gave like this java -cp %APP_PATH% and that doesn't
work...It does if APP_PATH has the correct value.
Try echo %APP_PATH% and see if it's what you expect. They plug whatever that returns into your java command.
Is this the correct way or how to do this ?That's the correct way. You APP_PATH must be wrong.

Add firewall rule with custom environment variable in program path

Hi,
We want to create a firewall rule for a program which is placed in folder which changes sometimes. I know you can add a firewall with the ProgramFiles environment variable like this:
netsh advfirewall firewall add rule name="Test Firewall rule" dir=in program="%%ProgramFiles%%\Test\Test.exe" action=allow security=notrequired
The environment variable ProgramFiles isn't expanded and if the Program Files folder is different on a system the rule still works.
We try to use this with a custom environment variable which we set a system environment variable with this command:
SETX SomeFolder "D:\Some Folder\Apr 2015" /M
If we use the command below to add the firewall rule in a batch file the environment variable SomeFolder is expanded correctly and the program path is added as a static path.
netsh advfirewall firewall add rule name="Some Firewall Rule" dir=in program="%SomeFolder%\AFile.exe" action=allow security=notrequired
Because the folder changes sometimes we want to change the environment variable SomeFolder and not remove the old firewall rule and create a new one. We want to add the environment variable SomeFolder to the program path as a (dynamic) environment variable
and not as the expanded path at the moment when the rule is added. If we use this command:
netsh advfirewall firewall add rule name="Some Firewall Rule" dir=in program="%%SomeFolder%%\AFile.exe" action=allow security=notrequired
We get the error:
          Windows Firewall with Advanced Security
          An error occurred while adding the rule.
          Error: The parameter is incorrect
          Status: The application name could not be resolved
          OK
Why can't we use %%SOMEFOLDER%% like we can use %%PROGRAMFILES%%? The same error is shown when we try to add the firewall rule through the management console 'Windows Firewall with Advanced Security'
W. Spu

Hi,
Based on my plenty of test with this problem, it seems like there is no better method to achieve your requirement. To add new policy to firewall, it would be better using general cmdlet. The path parameter like %%SomeFolder%% do have problem in add firewall
policy cmdlet.

Hi Hunter,
this one worked great. this is really cool man.

i created a environment variable saying
"HTTP_HOME=/home/oracle/oracle/product/10.2.0/http_1"
i need to go to $HTTP_HOME/Apaceh/Apache/bin"
and i give the command "./apachetcl start" for the http server to start running.
how can i make this apachectl variable to work so that form any directoy i should be able to give "apachectl start" comand and it runs.
Can u help me please.
i think if i do this also i can get some more understanding.
the command u gave worked great, but i did not understand the
LD_LIBRARY_PATH and CLASSPATH. what are they for.

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;
C:\oracle\product\10.1.0\db_1\jre\1.4.2\bin;

How do I use Embed with an environment variable in an Actionscript AIR project Flash Builder 4.7

I am using Flash Builder 4.7 to build an Actionscript AIR project. The project embeds a number of png files from my local directory and I have been using absolute paths which all works fine.
I have a laptop with which I want to start developing the same project - I set up a git repository that both the laptop and main pc can pull from and so I can get the source where I need it and push it back to the central repository.
My problem is that the absolute paths for the embed commands don't work on the laptop as it has a different filesystem setup (Windows 8 with one drive as opposed to Windows 7 with a SSD and a data drive). I thought the solution would be as easy as using an environment variable to specify the path which could then point to a different physical directory on both machines, i.e:
[Embed(source = "DEVELOPER_RESOURCES/graphics/are/here.png"]
I did a bit of research and there was quite a lot mentioned about setting up resource directories using path variables which I worked through but I just can't get it to compile. The Actionscript compiler just won't find the png files however I specify the path. I tried something with a FLEX project and the compiler didn't complain but I think this is because the compiler for FLEX uses a different convention.
[Embed(source ="/Project Name/DEVELOPER_RESOURCES/graphics/are/here.png"] works with FLEX but not Actionscript.
So does anyone have a recipe for using the Embed command referencing assets using an environment variable that works across multiple machines with different file structures?

I managed to find a solution on Windows which was to use symlinks and absolute paths. You an basically point one directory to another so I did something like:
mklink c:\developer_resources c:/the/local/path/to/my/resources
and then reference all resources as c:\developer_resources\...
Now as long as a developer machine has the right link (from c:\developer_resources to the place where the resources are kept) then it seems to work.
This doesn't however work for Mac and certainly isn't a solution for passing files between Mac and windows

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.
Li.etsuhin

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.

Environment variables like classpath,JAVA_HOME,path
