I'm trying to get Oracle installed.
If I type just sqlplus -V I get this error
Error 6 Initializing SQL*Plus
Message file sp1<Lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
However if I type
/home/oracle/product/11.1.0/db_1/bin/sqlplus -V
it works. I then set my PATH, ORACLE_HOME and export them. Everything works. If I close the terminal and reopen, I'm back to the start with orginal error.
How can I set my PATH and ORACLE_HOME permanently?
