In Oracle 10g release 2, the dbstart command includes an automatic start of the listener, so there are some differences between the two versions, but the following represents Oracle's preferred method for Oracle 10g. This method relies on the presence of an RSH server, which requires additional packages and configuration. This can be quite problematic when attempting to use this method under later Linux distributions, where rsh is deprecated.

As a result, I prefer to use the "su" command method. For a time the Oracle 12c documentation recommended using the "runuser" command in the "dbora" service. The latest version of the documents have reverted the using the "su" command.

However, you can specify that the dbshut script shuts down a set of databases while the dbstart script is not used at all. To do this, include a dbshut entry in the system shutdown file, but do not include the dbstart entry from the system startup files.

To automate database startup and shutdown by using the dbstart and dbshut scripts:. In this example, the values Y and N specify whether you want the scripts to start or shut down the database, respectively. For each database for which you want to automate shutdown and startup, first determine the instance identifier SID for that database, which is identified by the SID in the first field. Then, change the last field for each to Y.

You can set dbstart to autostart a single-instance database that uses an Automatic Storage Management installation that is auto-started by Oracle Clusterware. This is the default behavior for an Automatic Storage Management cluster. To do this, you must change the oratab entry of the database and the Automatic Storage Management installation to use a third field with the value W and N , respectively.

These values specify that dbstart auto-starts the database only after the Automatic Storage Management instance is started. Change the group of the dbora file to the OSDBA group typically dba , and set the permissions to LOG is a chronological log of messages and errors written out by an Oracle Database. Typical messages found in this file are database startup, shutdown, log switches, space errors, etc.

This file should constantly be monitored to detect unexpected messages and corruption. Beginning with Release 11g, the alert log file is written as XML formatted and as a text file like in previous releases.

The default location of both these files is the new ADR home Automatic Diagnostic Repository, yet another new dump dest in 11g.
