It is evident for any such relevant initialization parameter files, where there is no particular instance of server parameter files then there is always a persistent variable given to them from Oracle so that these can work on the basis of constant given to them. It is always advisable to make lesser parameter files when you are first creating a newer Oracle database.

Alter and Trace Log Files:

Each physical server when runs within specified hardware environment, it runs a background process and it makes associated trace files. When an internal error occurs while the server is running any instances, it creates dumps files about concerning error and store inside server for future administrative references. There are for two classes of dump files. The first part is related to errors intended for referring administrators and the second one related to find out the exact reason behind errors from Oracle support and help services.

In these second class of dump files, one can find detailed and constant information related to further improvement to tune applications and instances. From time to time Oracle sends updates and improves system performance by collecting all these relevant information from different servers and this can help in both ways as from all these gathered information Oracle sends relevant information and then sends critical system updates in order to satisfy exact customer and industrial needs.

Alert file is part of log files and this is essential to store error information about which way server is running. Alert files are set for special log files; it creates a set of alert log files in a chronological order in terms of messages and different trace errors.

Backup Files:

Backup files are an exact replica of database files, and it is used to replace the corrupt file. Most times, when particular files show error logs, or any media failed to log or deleting the original files by mistake there comes the urge to restore that files from backup locations. There are two ways backup files, one is user managed or manual backup files and the second one is automated backup files. In the second instances, automated backup makes a complete backup and it has severe load on physical capacity of the server.

In the first instance of backup file, user has to manually make backup processes, before making running server trial processes. In the second instances of backup processes, which are alternatively known as server-managed backup processes, which deal with scheduled backup processes, and the work of system administrator to install the correct backup file before making restoration of backup processes. In simple terms, backup processes help you to protect your database from out surge. Data loss and help you completely reconstruct a database from scratch and compensate any loss that might have happened due to extreme data losses.
