SQL Developer

I run win xp sp 2, and oracle client 9.2.0.6 trying to connect to a database in unix environment.

I have two issues

1) I use ldap.ora and sqlnet.ora to connect to the databases.

Under the TNS tab, when I use the service name I get the error

"Status : Failure - no ocijdbc10 in java.libray.path"

I can only connect using the basic connection by specifying thee host and port.

2) Connecting with basic method, running a debugger, I get a message in Debugging area as,

Connecting to the database user_a@connect_str.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: ALTER SESSION SET PLSQL_COMPILER_FLAGS=INTERPRETED
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( 'xxx.xx.xxx.xxx', '1519' )
ORA-30683: failure establishing connection to debugger
ORA-12535: TNS:operation timed out
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
Process exited.
Disconnecting from the database user_a@connect_str.


Any help is much appreciated.

So, far it looks like a great tool in making...
Thanks
