Yesterday I had case, my developer can't access db with TOAD but he can access it on machine.
Solutin :
Check : $TNS_ADMIN/sqlnet.ora
There are lines :
tcp.validate_checking = yes
tcp.invited_nodes = ....
First line is sett db should check node who can access db. yes means db machine would check who access the db.
Second line is define nodes who accepted to access db.
Both of lines is addition, after install db, the lines is not exist, we should add those lines for security issue.
