installing Oracle Instantclient on Linux without setting environment variables?

Question

Oracle\'s instructions specify setting LD_LIBRARY_PATH. This makes my application dependent on random users\' configuration and is very troublesome to set up.

How can I

Answer 1

or you can try using this command

Linux

sqlplus user/pass@'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=port_number)))(CONNECT_DATA=(SID=sid)))'

Windows

sqlplus user/pass@"(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=port_number)))(CONNECT_DATA=(SID=sid)))"

so you don't need the tnsnames.ora
