环境变量设置  Solaris windows

Solaris Example
The following Solaris example sets the environment variables thatare required for
selecting an instance. When switching between instances withdifferent Oracle homes,
the  ORACLE_HOME  environmentvariable must be changed.
% setenv ORACLE_SID SAL1
% setenv ORACLE_HOME /u01/app/oracle/product/10.1.0/db_1
% setenv LD_LIBRARY_PATH/usr/lib:/usr/dt/lib:/usr/openwin/lib:/usr/ccs/lib

Most UNIX installations come with two scripts, oraenv  andcoraenv, that can be
used to easily set these environment variables. For moreinformation, see
Administrator's Reference for UNIX Systems.
