    ftp your tnsnames.ora file from your server to Client and try.
    ie. update your client tnsnames.ora with your server tnsnames.ora

    Try this:
    TNSPING (or TNSPING80 depending on your client version)
    First try this:
    TNSPING testdb
    see what happens and report. If fails try
    TNSPING testdb.legend.com

    Also rename sqlnet.ora (if it's there) on client machine to something else(to make it invisible to Oracle) and retry.

    hi, Chandra and JDoyle:

    Thank your help !
    Chandra, I compared tnsnames.ora in client side and server side, find unique different is tnsnames.ora of server using hostname in "address" section, but in client, it using ip address in "address" section. i must to be add alias of server machine to /etc/hosts of clients , then i can connected to database. but when i removed that alias and changed alias to ip address , same error occured. why? i must be resolve this problem.
    JDoyle, i also renamed sqlnet.ora to other. but it also can't connected to my database.
