Unable to set JAVA_HOME environment in bash shell

[Former Member]

hi all,

I am a new user in our sap environment in solaris boxes. we use WRQ Reflection to run the X-Windows for using Java tools like Visual Administrator.

Since my profile is new,the environment variable JAVA_HOME for my user profile is not set.

The default shell is bash.but i dont know how to set the enviroment variable to start the java tools.

Please help me where can i find the .bash_profile and how to set it..( i can execute unix commands, but i am not an expert )

Help would be greatly appreciated and rewarded.

Thank you all for your time.

moved to the Unix forum, as this question is not Linux related

Profiles are always in your home directory.

Logon as root

vi .bash_profile

then press "SHIFT" "G"

enter

export JAVA_HOME=<yourpathtojava>

- press "ESC"

- enter ":x"

logoff - and logon as root.

Then check with

echo $JAVA_HOME

if the path is set.

Markus,

Thanks for your quick reply.

I couldn't find the .bash_profile in either /home OR /home/<my_user_id>

instead i see .bash_history file under /home/<my_user_id>

i cannot login as root.but i think i have the permissions to edit and modify files ( i could do with other files ) how do i check my own permission ?

Can i do it on my own if i have the necessary permission or i need unix admins help ?

Please help..simple thing..but eating my brain for 2 days..!

Appreciate your time.

SAP installation must be done as user "root". You don't necessarily need to logon as root but can you an

su - root

I don't know the root password to switch the user ( su ).

Is this mandatory to have root permissions to set the environment variable ?

Can i do it with you guys help or I need to request solaris admins help as i may not have necessary permissions. since i am able to edit and modify other files, i think i should be able to do it.

Please help..

when we try to su - root , we cannot use our password which is meant for our id and i don't have root password.

environment setting has to be done by the root or we can do it if we have necessary permissions ?

appreciate your time and help.

su - root means

"S witch User"

the "dash" means that the environment from the new user should be taken

the second argument is the username

Bash is not a default shell on Solaris so it won´t use the normal enviornment.

Create a new file with the name

.profile

in your users home directory and set

export JAVA_HOME=<yourpath>

Markus,

I found the jdk path - /usr/jdk/j2sdk1.4.2_12

And tried to export the JAVA_HOME and Ofcourse it works..Thanks !

i was able to start the application..but its only for the current session.

( I used export JAVA_HOME=/usr/jdk/j2sdk1.4.2_12 which is my jdk location )

But, when i tried to see .profile or .bash_profile to make it permenant, none is found.

I tried to create a .profile as you said..but when i tried to save the file after putting export command in there, i am not able to save,getting an error " Operation not applicable "

Is that because i don't have enough permissions ? How do i check my own Permissions ?

Please help...

I suggest you contact your Unix admins. Usually a user should be able to write/create files in his home directory.

when i told this to my colleague, he asked me to create any file ( not a .profile )and put the commands whatever i want and execute it startup.

i will try for that option..please help if you have any idea..
