Backing Up Oracle - Computing at Cornell

Chapter 7. Day-to-day monitoring of Oracle backups on UNIX
Once the TDP for Oracle implementation and environment has been set up,
as described in the preceding chapters, it is recommended that the regular
day-to-day tasks be monitored and automated for more efficient execution.
This chapter details some of the processes and tasks which can be used.
7.1 Automating database tasks
There are some Oracle database tasks which can be automated as detailed
in the following sections. These are best determined by the Oracle DBA.
7.1.1 Starting SQL*Net and RDBMS services at system reboot
During the boot of a UNIX system, /etc/inittab is processed. The file
/etc/inittab controls process dispatching by init. The processes most
typically dispatched by init are daemons — but there is also a section in the
inittab, where user defined scripts are executed.
We chose to start Oracle services when the system is switching to run level 3,
which is also called extended multi-user mode. In this mode, all important
system resources are available.
On both systems, AIX and Sun Solaris, we placed a kill-script and a
start-script into:
/etc/rc.d/rc3.d for AIX
/etc/rc3.d for Sun Solaris
The start scripts first start SQL*Net services, and then the RDBMS is started.
Because it runs under root authority, a superuser command to the Oracle
instance owner is issued. An example of the start script follows:
