Setting my bash shell enviroment variables

my experience on managing oracle on linux is very little.My background is generally on windows server.
Every time i want to use an oracle application i always have to set the environment variables like $oracle_home.How can i make this setting permanent.I have tried doing this when logged on as 'oracle' user using the command vi .bash_profile. But if i try to save it i get the annoying message that the file has not been opened for editing.
In summary how can i open my bash profile file for editing.
Thank you
Charles

if i try to save it i get the annoying message that the file has
not been opened for editing..bash_profile is normally updateable by the owner only (or by root). If you get that message, then probably you're trying to do that as another OS user. Please try the following :
$ cd /home/oracle # (where /home/oracle is the oracle OS user's home directory)
$ ls -la .bash_profile
-rw-r--r-- 1 oracle dba 1687 May 16 11:39 .bash_profile
$ id
uid=500(oracle) gid=500(dba) groups=500(dba) context=root:system_r:unconfined_t:SystemLow-SystemHigh

DIsplay variable setting ReflectionX in Bash shell

Everyone,
Can somebody help me with setting display variable for running Configtool in ReflectoinX in Bash shell.
Appreciate your time. Thanks.

> It looks like it will work..only thing is that we need to set display variable..i assume.
If you logon as <sid>adm then no DISPLAY (or other variable) must be set if you use XDMCP.
> I am doing sudo for opening a java tool which needs x window..other x windows like visual admin is working fine but for configtool, i am getting this error saying display variable is not set.
That's what I was saying - do not switch users (sudo, su etc.) - that will delete the environment and invalidate .Xauthority.
> I am not given the <sid>adm password, can i just use X window with sudo OR do i need to get the <sid>adm password to start the configtool..
In that case I would not use XCMCP to connect but a pure telnet, do sudo and then set the DISPLAY to
<your-IP>:<reflection-display>. the latter can be found when open Reflection in the lower part of the configuration window.

How to set enviroment variables for Inso Filter

Hi everyone,
I want to convert word documents to html using CTX_DOC.Filter.According to the documentation,I know I neednot set the 'Inso Filter'in the preference when creating index,but I must set enviroment variables for Inso Filter.
I found the following instructions for it in the 8.1.5 documentation,but I can't understand it well.Is there anyone can tell me how to set enviroments variables for Inso Filter on Windows2000 Server?(My DB version is 8.1.7EE)
Environment Variable Locations
All environment variables related to Inso filtering must made visible to interMedia Text. Set these variables in the following locations:
listener.ora file. This makes the environment variables visible to the extproc PL/SQL process.
The operating system shell from where ctxsrv server is started. This makes the environment variables visible to the ctxsrv process, which does background DML.
Any suggestions are apreciated

How to set Enviroment Variable

Bash shell does not recognise 'java', 'javac' commands (Linux command line)

i' ve used javac and java compile & execute commands to build the same application on the DOS command line with Windows - no problem.
But when I try to compile the same file on the command line under Linux Redhat (7.1) using Bash shell i get <bash: javac: command not found> and <bash: java: command not found>.
In both cases I'm using j2sdk1.4.2 downloaded from java.sun.com for Windows & Linux respectively.
I make sure I have both the javac and the file I want to compile in the same directory ../j2sdk1.4.2/bin for both the Windows and the Linux applications.
Is there something I need to do to get bash to recognise javac, java etc? Is there a different setup procedure?
Any angles on this are much appreciated ..

Have you tried these correctly..
Set the CLASSPATH environment variable to include whichever directories you like, eg (on bash) type:
export CLASSPATH=$CLASSPATH:.:<your java dirs>
To make java easier to run, put the directory in which it is installed into your path:
export JAVA_HOME=<where you installed java>
Then do
export PATH=$PATH:$JAVA_HOME/bin
verify it has worked by simply typing
java
You can put all of these commands into the .*rc file for your shell, so that they are executed every time you open the shell. So if you are using bash you can put them into ~/.bashrc
Read up setting the PATH and CLASSPATH for more info.
This shall resolve the issue .

How to use enviroment variables in JSP code?

I�m developing a web server with JSP�s, and I need to move the application to others computers. I need to access to a directory, but I don�t know it because the user can install the Application in the directory he wants. So I need to access to that directory in the JSP code.
The directory is "C:\Program Files\....\tomcat\webapps\ROOT\upload". I have the CATALINA_HOME enviroment variable defiened as "C:\Program Files\....\tomcat\", so I need to use something like "CATALINAHOME\\webapps\upload\", but I don�t know how to mekr the JSP code to understand the enviroment variable CATALINA_HOME.
I�ve tried with %CATALINA_HOME%, but the Tomcat server doesn�t recognize it. How can I access to that directory?
Thanks (Sorry about my english)

My JSP�s are in: %CATALINA_HOME%\webapps\ROOT\
I wan�t to access to %CATALINA_HOME%\webapps\ROOT\upload\
My JSP code:
<% ...
String DPATH = "C:\\Program Files\\JBuilder7\\jakarta-tomcat-4.0.3\\webapps\\ROOT\\upload\\";
File newfile = null;
newfile = new File(DPATH+filename);
%>
I want the JSP to locate the directory \webapps\ROOT\upload\ without knowing the complete route "c:\Program Files\...", because I have the enviroment variable CATALINA_HOME with the value "C:\Program Files\JBuilder7\jakarta-tomcat-4.0.3\". SO the user of the aplication only has to set the CATALINA_HOME variable and the aplication should access the upload directory throught the CATALINA_HOME variable.
I can�t explain it better. Sorry.

How to pass a result of SQL query to shell script variable

Hi all,
I am trying to pass the result of a simple SQL query that only returns a single row into the shell script variable ( This particular SQL is being executed from inside the same shell script).

Try:

Any tips on Controlling interactive bash shell on Cygwin via Java process?

Ideally, I'd like to be able to control an interactive bash shell on Cygwin from a Java process. But for starters, I want to do 'ls > /cygdrive/c/fred.txt'. The little program to do this, below, doesn't work. It simply runs without error.
Any ideas? And also, any tips on doing a fully interactive shell?

package com.treelogic_swe.real_estate_explorer.utils;

import java.io.InputStream;

What do you mean by this? Do you just want to start a bash shell, and have it's input and output come from and go to your Java program?
Please be specific about what you want, as there are a couple of interpretations for what you said. You need to understand the differences and relationships among terminals, shells, shell builtins, and executables.
You'll want to read this:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
from a Java
process. But for starters, I want to do 'ls >
/cygdrive/c/fred.txt'. The little program to do
this, below, doesn't work. It simply runs without
error.
, <, |, and others are specific to the shell. When you're in a terminal, and you type ls > /tmp/zzz, it's the bash shell that interprets the >. Cygwin doesn't know anything about it. ls doesn't know anything about it.So if you want to to that, the command you'd execute from Java is not ls, but bash (or some other shell). You'd then tell bash to execute the rest. I'm not sure what the command line arg is for bash to tell it the rest of the command line args are a command that bash should interpret and execute. I think it might be -c like it is for zsh. So you'd need to do something like Runtie.getRuntime().exec("bash -c 'ls > /tmp/zzz'");

AppleScript: How to let AppleScript use the same environment as Bash shell does?

Howdy!
I can run AppleScript from Bash shell.
I can also run Bash shell from AppleScript.
So my question is when I run a Bash shell script from AppleScript, I am hit with a path problem.
Suppose my AppleScript is under ~user/a.scpt. I want my AppleScript to know its current path (i.e. ~user/a.scpt).
So a quick snippet test in my AppleScript shows that AppleScript always begins from the root directory:
do shell script "pwd"
So let's do a workaround AppleScript like this:
tell application "Finder" to set currentDir to (target of front Finder window) as text
do shell script "cd " & (quoted form of POSIX path of currentDir) & "; pwd"
This works. However, this approach poses a potential danger.
Suppose when I run this AppleScript for a bash script, I inadvertently clicked other Finder Window. That would result in execution of bash script in that newly clicked Finder Window, resulting in a big mess.
Is there a better way to let the AppleScript to know its current path?

The following is what your Applescript environment looks like, so plan accordingly. If you want your Applescripts to be portable to other user environments, you should NOT depend on your environment, but rather embed all the environment knowledge you need into your script.

Bash shell scripting

Dear Mac Users:
I have a bash script which I copied from a bash book to learn how to use bash. Whenever I try to run it on Linux (cygwin--Windows Linux interpreter) it throws an error that something is wrong with the syntax.
But when I try to run the same script on my Mac using Terminal.app the bash shell throws an error saying access denied. I chowned a copy of bash and referenced this copy in my script but I still get the error. I also chowned the script to the user account on my Mac. Why can I not run the script?

Enviroment variables!

I have the java card kit 2_2_01. I have set the enviroment variables(at least i think so, i just did what the pdf says) and when I am trying to emulate one of the samples included,the message in the dos-prompt enviroment says
Out of enviroment space.
Exception in thread "main" java.lang.NoClassDefFoundError: apdutool/bat
Generally it does that in every tool that I am trying to use. Thank you in advance for your interest!

How is your environment set up ?
The JRE is interpeting apdutool.bat, to apdutool/bat !
Don't put apdutool.bat in your CLASSPATH. Just add the javacard \bin to your PATH. CLASSPATH is for Java ONLY, PATH is for Windows system environment

And even other blog tell to point to the home where is all my Oracle tolls which in my case should be C:\Oracle\Middleware. What is the purpose to set this system variable? I can run weblogic, OSB and OER without that. The only reason I setted BEA_HOME was to use harvester and untill now, apparently there are no diference what the path I set the variable with.

How to get current directory and enviroment variables

Hello,
1.- Is there a global variable to get the actual (project, where is DSB and DSQ files) directory?
2.- Is there a way to get User directory like reading enviroment variables from Operative System?
Thanks in advance.
PD: I'm using Dasylab12
Solved!
Go to Solution.

Yes, use System Strings
For example, ${DATA_FOLDER}.
The easiest way to get the list is to right click and select Global Strings. The bottom half of the dialog box lists system strings, including date, time, the name of the worksheet, with or without path, the DEFAULT folders for worksheet, data, other, black box, etc.
