How Do I Interpret Output Of Set?

OpenLink's Unix components require the following ODBC environment variables to be set:

Variable
Definition
CLASSPATH A JAVA client variable that passes the full path to an OpenLink JDBC .jar file. This variable should appear on all systems that contain OpenLink JDBC client components.
LD_LIBRARY_PATH A generic library path variable that appends the full path to OpenLink's lib sub-directory. This variable should be set on any machine that contains Single-Tier or Multi-Tier client or server components.
LIBPATH An AIX library path variable that appends the full path to OpenLink's lib sub-directory. This variable should be set on any AIX machine that contains Single-Tier or Multi-Tier client or server components.
ODBCINI Passes the full path to ~/openlink/bin/odbc.ini. This variable should be set on any machine that contains Single-Tier or Multi-Tier client components.
ODBCINSTINI Passes the full path to ~/openlink/bin/odbcinst.ini. This variable should be set on any machine that contains Single-Tier or Multi-Tier client components.
OPENLINKINI This Single-Tier variable passes the full path to ~/openlink/bin/openlink.ini. This variable should be set on any machine that contains Single-Tier client components.
PATH Appends the full path to OpenLink's bin sub-directory. This variable should be set on any machine that contains Single-Tier or Multi-Tier client or server components.
SHLIB_PATH An HP/UX library path variable that appends the full path to OpenLink's lib sub-directory. This variable should be set on any HP/UX machine that contains Single-Tier or Multi-Tier client or server components.

set output should be checked against ls output for the relevant directories structures. This shows:
  1. Which environment variables are set.
  2. Which environment variables are missing.
  3. Whether or not variable paths are correct.
  4. Whether or not permissions prevent access to files or directories.
OpenLink's drivers also require database specific environment variables. set should be run before Single-Tier client installation or Multi-Tier server component installation. Users must insure that the relevant database native environment variables are set. This enables OpenLink's installers to detect the settings and write them into Single-Tier openlink.ini or Multi-Tier oplrqb.ini file.
