Hi,

Im a oracle newbie and I came across this issue:
We have 2 oracle instances, and frequently we query one instance from the other (select * table@instance2)
This morning, the password was changed. While before I was able to query the other instance, now I am getting login/password incorrect error.
It's a configuration issue but being new to oracle I dont know where to look for it.
Any suggestion is highly appreciated.

Thanks,

Vlad
