Oracle, by default, uses $ORACLE_HOME/network/admin to stor the tnsnames.ora,
sqlnet.ora, listener.ora, snmpro.ora and snmprw.ora files for configuration
of the Net8 services. If you declare a TNS_ADMIN variable oracle will use
that location for these files. It allows you to keep your networking config
files separate from the oracle distribution files. Example: On our
development machines we have multiple oracle homes of diferent versions
8.0.x, 8.1.7, etc. All these versions use the same TNS files from a
directory under the $ORACLE_BASE. Our setup is:
/usr/oracle
admin
common
<SID>
product
8.0.5.1
8.1.7
jre
oui
oraInventory
network
admin
log
trace
We then use the 8.1.7 listener and OEM agent against all db's. We have one
sqlnet.ora and tnsnames.ora configuration for all instances on the machine.
One place for log and trace files for TNS issues. It makes administration
easier.
The LD_LIBRARY_PATH is a variable that tells applications working with the
oracle client where the oracle libraries are. It is version dependent and
should be set with the oraenv. Normally it is $ORACLE_HOME/lib.
If you are not using oraenv then you need to make sure that it is exported
before you start doing your oracle stuff. All of this assumes that you are
working with oracle on a Unix machine.
The discussion applies to NT also except these variables are specified in the
registry under \\HKEY_LOCAL_MACHINE\Software\Oracle
