Hi friends,

Ora 9.2 on win2000

I'm quite confused by this error, ora-12637 in our server.
When I use the command:

c:\> sqlplus system/manager ( it can connect)

but if i use

C:\> sqlplus system/manager@ora9 (it produce ora-12637)

the above commands is issued on the server itself.

but when I issue the command on the client PC

c:\> sqlplus system/manager@ora9 (it can connect ) I use the same
tnsnames.ora on the server....

Why am i having error on the server and not on the cliemt?
