Question

Can't acces my CentOS/oracle 11g database

When I try to connect with TOAD this appears:
TNSADMIN environment variable is not defined
EZCONNECT is not the first naming method in NAMES.DIRECTORYPATH which may conflict with other naming methods specified.

Plus I do not know what to put on the service name section

Hi @javierruiz
You’re probably better off asking in a Oracle forum, but when I searched a bit, it seems like you’re probably missing the Oracle path from $PATH:

The TNSADMIN environment variable is used to specify the directory location for the tnsnames.ora file. The TNSADMIN environment variable can be defined in the following ways:

For UNIX users, the order in which Oracle searches locations for Oracle Net files like sqlnet.ora and tnsnames.ora are in this order:

  1. $HOME for hidden files only (i.e., .sqlnet.ora and .tnsnames.ora)
  2. $TNS_ADMIN
  3. $HOME
  4. /etc or /var/opt/oracle (depends on platform)
  5. $ORACLE_HOME/network/admin

Don’t hesitate to contact me if you have any trouble !
