Thanks for your reply , netstat -nr says But my windows box is in the same subnet than the ntop box. And i can connect to it whith ssh. So i don't think routing is bad .

but it works when being connected with the oracle user. And i don't know why... ;) Anyway, now it works with all users :)

Solved yesterday. ldd command tells me why it doesn't works ! On each of our productions systems oracle is installed under /<host name>/oracle/..... and there is a link /oracle -> /<host name>/oracle We never use the real path but we use the path given by the link (/oracle/... ) for...

I bought a two proc machine . lscfg -v | grep proc gives me But... lsattr -El aio0 gives me and ps aux | grep -w aioserver | wc -l gives me : 160 The strange thing is that i read that number of aioserver will be : number of proc x max aio servers. So I waw expecting 80 aioservers...

Ok, thanks you all for answering. Marco.
