Oracle Problem Resolution

oracle| Solve | The problem
These days it is necessary to deploy a system to Linux as a prototype of the system development. System with the database is Oracle 9i Linux, build a database, guide data for a long time, finally thought it was done, but the start of the monitoring when the results of the error, can not start, really depressed dead. There was some fear of Oracle, and some of the parameters were not chosen when the database was created. Ah, there is a problem, is really afraid of Oracle. After a few hours or not, that day is the weekend, forget it or do not get it next week. Returned home with a weary heart. Today Monday work, still need to get Oracle ready Ah, or the old problem, monitoring can not start. Replaced an instance with the old database in the previous system. Or not, today is Monday, the mood is very certain, I think the machine environment is certainly the problem, I suddenly want to have, look up the/etc/hosts file, sure enough the machine's IP address is different, modified to the current IP address is good. That's good, I guess I don't have to fear Oracle any more.
