[mapserver-users] oraclespatial connect error

[Yu-Hsin Chen]

I'm on Mandrake Linux ProSuite 8.0.  Oracle is 8i 8.1.7 for Linux.  I
can access my remote database through sqlplus or a perl cgi program
without problems.  Mapserver was compiled with oraclespatial and the
path was pointing to the correct $ORACLE_HOME path.

I won't be able to try anything until Monday.  So I will create a local
database to see if I at least can conquer the connect problem.

After that I'd have to work with the spatial issues.  I'm not familiar
with Oracle spatial implementation.  My need is simple: I'd like to be
able to retrieve locations from the database based on certain criteria
and plot them on the map.  That's why in my original message I put the
'DATA' statement that way.  I thought I could pull the latitude and
longitude data and plot them as circles (that's how I understood the
Mapserver reference manual) with that statement.  If that's not the
case, Rod, I think I'll need assistance later.

Thanks.

Yu-Hsin

Which binary of mapserver are you using? Windows or Unix? -- just for
curiosity

Also, you could try to track the error by running sqlplus and trying to
connect to the database. You should get the same TNS error when you try
to
connect.

Hello,

don't you have more than one Oracle install on your local server ? May
be
the
Oci don't look in the right tnsnames.ora file ?
