Setting up Oracle Instant Client 12 on Debian Jessie

debs

Convert rpm files by alien as usual.

Configuring tnsnames.ora

without environment variables

If a tnsnames.ora file is used, you can easily put it to /etc as Oracle Instant Client searches for that file in /etc.

with TNS_ADMIN

Set TNS_ADMIN environment variable to the path where your tnsnames.ora is if it is not located in /etc.

with ORACLE_HOME

If an environment variable ORACLE_HOME is set, Oracle Instant Client searches for tnsnames.ora also in $ORACLE_HOME/network/admin.
