# This routine is used to condition a C shell user's environment
# for access to an ORACLE database.  It should be installed in
# the system local bin directory.
#
# The user will be prompted for the database SID, unless the variable
# ORAENV_ASK is set to NO, in which case the current value of ORACLE_SID
# is used.
# An asterisk '*' can be used to refer to the NULL SID.
#
# 'dbhome' is called to locate ORACLE_HOME for the SID.  If
# ORACLE_HOME cannot be located, the user will be prompted for it also.
# The following environment variables are set:
#
#	ORACLE_SID	Oracle system identifier
#	ORACLE_HOME	Top level directory of the Oracle system hierarchy
#	PATH		Old ORACLE_HOME/bin removed, new one added
#
# usage: source /usr/local/coraenv
