There is a database running in an AIX partition on a p570 server. The database administer wants a script run to cleanly shut down the database before the operating system is shut down. As system administrator,which of the following would meet the database administrator requirement?

A.Create an /etc/rc.shutdown file containing instructions to shut down the database

B.Create a DLPAR script on the HMC that issues an operating system command to run the database shut down script whenever a shutdown LPAR command is run on the HMC

C.Use the chitab command to change the Action field of the appropriate /etc/inittab entry from Respawn to Once

answer:A
OS shutdown前会自动调用/etc/rc.shutdown这个脚本的

The /etc/rc.shutdown file is checked each time a shutdown
command is issued. If the file exists, it will be run; otherwise, the system will
perform a regular shutdown depending on the flags that are used to bring the
system down.
Tip: /etc/rc.shutdown must be set as executable before it can called by the
/usr/sbin/shutdown script.
