# If ORA_CRS_HOME is still not right - that is, it does not
# contain our libraries, it means that the script is being run before it is
# instantiated with an env variable that is not right (perhaps a db home instead
# of a GI home).  We will try one last time to find a good
# GIHome to run from.
# This is because okadriverstate must be able to run
# before okaroot is run - the patch and install setup uses
# this script to tell if OKA is supported, and it is run
# before our scripts are instantiated.
# So we try and use the path we are running from, where we assume
# that this is a GI home.

    # Since we are only concerned with finding the library
    # we don't need to find the canonical path or anything like that.
    # If we were connecting to ASM, we would need the same canonical
    # path that ASM was running from.
