Hi to all

I have been trying to connect a db(ATDMPQA Oracle 9i) from this current 10g db but I encounter TNS-12535: TNS:operation timed out. Please help as I really cannot figure where the mistake was... Thanks.

Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY = o3_
ora.NECSS.NEC.COM.SG) (PROTOCOL = TCP) (Host = 138.141.10.5) (Port = 1531))) (CO
NNECT_DATA = (SID = ATDMP) (GLOBAL_NAME = ATDMP.NECSS.NEC.COM.SG)))
