Well, i've tryed everything, but the real problem is that this version of Informix ODS (7.23) seems not work well with W2K, cause everything is correct, but the database server does not change from offline to online, even login in with the user informix and doing all that was suggested here. The database simply can't change to online mode.
The database works, the services starts, i can access the tables, insert data and other stuff like this, the only problem is that i can't manage the logs, start the continous logical logs backup, setup the dbspace and etc.
I guess i'll give up, if anyone has more ideas please help me!
Regards to everybody!
