Set/Export Unix Variables through forms [message #110723]

There is a forms built-in called TOOL_ENV.GETVAR which gets Unix environment variables.

Is there a way to Set or Export Unix environment variables which will PERSIST longer than a standard Host command variable. That is, I have an environment variable DEBUG which I set to 0 (zero) with a DEBUG=0 command before starting my Unix/Linux oracle command. My application looks at this environment variable to see whether I want lines written to a text file. I can turn it on or off BEFORE I start the session, but I want to be able to change its value WHILE the session is running. A 'host' command starts a new session and does not update the variable in the current session.

Any ideas?

Use :GLOBAL.variable_name.

Check out the docs for more info concerning global variables.

C scripts can't read globals.

Create a file debug and alter the contents from 0 to 1. If you use utl_file, you can modify files on the server.

Found that 'C' has a 'setvar' facility. We used it.
