Oracle database connection

Oracle 11g client installed in a public place on c:\ in windows. For example, c:\oracle\production\client_1, but tnsnames.ora and sqlnet.ora files are located in another driver. For example, e:\oracle\files\tnsnames.ora and sqlnet.ora. The two files can't be copied to Oracle home on c:\. Can the databases in the tnsnames.ora be connected and how to do that?

Agreed, if you are comfortable doing so, the TNS_ADMIN variable may be set as a system default under the CP / system / advanced / environment.  Secondly, consider placing a shortcut to the E: folder in your other oracle home(s).

For the fun of it, please always remember to backup your source file prior to making ANY changes with its content.

there is no need to create a link e:
the unc patch can be specified too

set tns_admin=\\server\share

as a backup plan copy the tnsnames.ora and sqlnet.ora to a local folder
when the \\server\share becomes unavailable it's possible to revert
too see how this works:
start tnsping with a share or reverting if it fails:
md c:\oracle\tns
robocopy \\server\share c:\oracle\tns *.ora
if exist \\server\share ( 
  set tns_admin=\\server\share
) else (
  set tns_admin=c:\oracle\tns
)
tnsping db_alias

Open in new window

Hi,
You can also set the TNS_ADMIN in the registery for a specific ORACLE_HOME.
Note that environment variable takes precedence on registery.
Regards,
Franck.
