Hi guys

Recently I upgraded my PC with Oracle 9i. Though the database part is working fine now I am having troubles with connecting developer 6i. Please go through the tnsnames.ora entries down and suggest me what changes I must do so that I can connect the developer with Database.

My Oracle 9i tnsnames.ora entries are:-
# TNSNAMES.ORA Network Configuration File: I:\ORANT\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

INST1_HTTP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rajesh)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = SHARED)
(SERVICE_NAME = MODOSE)
(PRESENTATION = http://HRService)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

PERSONAL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rajesh)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = Personal)
)
)

Forms 6/6i entries are as following:-

Beq-local.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = BEQ)
(PROGRAM = oracle80)
(ARGV0 = oracle80ORCL)
(ARGS = '(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq))) ')
)
)
(CONNECT_DATA = (SID = ORCL)
)
)
Tcp-loopback.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(Host = 127.0.0.1)
(Port = 1521)
)
)
(CONNECT_DATA = (SID = ORCL)
)
)
TcpExample.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(Host = Production1)
(Port = 1521)
)
)
(CONNECT_DATA = (SID = ORCL)
)
)
SpxExample.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = SPX)
(Service = Server_lsnr)
)
)
(CONNECT_DATA = (SID = ORCL)
)
)
NmpExample.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =

(Server = FinanceServer1)
(Pipe = ORAPIPE)
)
)
(CONNECT_DATA = (SID = ORCL)
)
)
CMExample.world =
(DESCRIPTION=(address_list=
(ADDRESS=
(PROTOCOL=tcp)(PORT=1610)(HOST=CM_SERVER))
(ADDRESS=
(PROTOCOL=tcp)(PORT=1521)(HOST=LSNR_SERVER)))
(CONNECT_DATA=(SID=ORCL))
(SOURCE_ROUTE=yes)
)
extproc_connection_data.world =
(DESCRIPTION =
(ADDRESS =
(PROTOCOL = IPC)
(KEY = EXTPROC%ORACLE_HOME_ID%)
)
(CONNECT_DATA = (SID = extproc)
)
)
kazema.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(Host = 131.102.2.200)
(Port = 1521)
)
)
(CONNECT_DATA = (SID = kazema)
)
)
PERSONAL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rajesh)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = Personal)
)
)

The PERSONAL database info was copied from the tnsnames.ora file found with database installation path. I do get replies while using tnsping commands available with both forms 6/6i and Oracle 9i. Please help.

Thanks in advance.
