env statements

[Brett Penza]

I am changing an env statement in HP 9000 Unix box.
SHLIB_PATH=/opt/vertex20/lib

When I do this, my program still does not see files in this directory.

I'm wondering if I need to REBOOT THE system for changes to ENV to take place. Or if there is some procedure I must run to get ENV variables to become active. Thanks. for help

Which location are you changing the path in? The /etc/profile, or ~/.profile?

Is the variable actually set? Go into a shel and enter "env", look for the variable to confirm.

Hi,

SHLIB_PATH=/opt/vertex20/lib
export SHLIB_PATH

This should work. I think that you forgot to export it.

Hi,
you have to check if the searching is enabled.

use

chatr
to see and

chatr +s
to enable searching


after that,
you have to simply re-load the env.

as your user in your homo

. ./.profile


or just logout/login


HTH,

Hi:

You need to export the modified variable. You can do this in one line as:

# export SHLIB_PATH=/opt/vertex20/lib

Yes, you should export the variable. Also, if this is a regular requirement,...

a) Place it in a profile script
b) Ensure that you include any existing contents of the SHLIB_PATH variable (Oracle uses this variable as well!) if it already has existing contents.

ie export SHLIB_PATH=$SHLIB_PATH:/opt/vertex20/lib

NB. No users were harmed during the coding of this script (more's the pity). Ian

I'm just retyping a different path at the root prompt.
ie,.
root:\SHLIB_PATH=/opt/vertex132/lib

Then when I type "env" It does show the change that I have made.

I'm just not sure if this change is in place for everyone, or is there some wierd thing going on here. Because the program can't find the files that are in that directory when
it runs.

Thanks for response.

Question - does the program start as another User, or is it started using a script that may wipe out environment variables that were set?

The following command may be better...:

# export SHLIB_PATH=/opt/vertex20/lib:$SHLIB_PATH

in case there is already some value in SHLIB_PATH and your program needs to have access to more than one library paths.

Hello!

If you made this in the workspace that you after try to run that's ok (for feature better to put in you enviroment files)
Check with the chatr that it find
the library.
