# default.env - default Forms environment file, Windows version
#
# This file is used to set the Forms runtime environment parameters.
# If a parameter is not defined here, the value in the Windows registry
# will be used. If no value is found in the registry, the value used will
# be that defined in the environment in which the servlet engine (OC4J
# or JServ) was started.
#
# NOTES
# 1/ The Forms installation process should replace all occurrences of
# <percent>FORMS_ORACLE_HOME<percent> with the correct ORACLE_HOME
# setting, and all occurrences of <percent>O_JDK_HOME<percent> with
# the location of the JDK (usually $ORACLE_HOME/jdk).
# Please make these changes manually if not.
# 2/ Some of the variables below may need to be changed to suite your needs.
# Please refer to the Forms documentation for details.
#
ORACLE_HOME=C:\DevSuiteHome_1
#
# Search path for Forms applications (.fmx files, PL/SQL libraries)

# The PATH setting is required in order to pick up the JVM (jvm.dll).
# The Forms runtime executable and dll's are assumed to be in
# C:\DevSuiteHome_1\bin if they are not in the PATH.
# In addition, if you are running Graphics applications, you will need
# to append the following to the path (where <Graphics Oracle Home> should
# be replaced with the actual location of your Graphics 6i oracle_home):
#
# ;<Graphics Oracle Home>\bin;<Graphics Oracle Home>\jdk\bin

# -------------------------------
