5. The CRS stack

The srvctl stop syntax for shutting down RAC, ASM, and node

applications is described in the appendix “Server Control (SRVCTL) Reference”

in Oracle® Real Application Clusters Administrator's Guide 10g Release 1

(10.1) Part No. B10765-02. Also see the chapter “Pre-Installation Tasks for

Installing RAC on Linux-Based Systems” in Oracle Real Application Clusters

Installation and Configuration Guide 10g Release 1 (10.1.0.2.0) for AIX-Based

Systems, hp HP-UX PA-RISC (64-bit), hp Tru64 UNIX, Linux, Solaris

Operating System (SPARC 64-bit), and Windows Platforms Part No. B10766-

04.

Stop all listeners on each system in the cluster by typing:

$ $ORACLE_HOME/bin/lsnrctl stop listenername

Shut down CRS on each node by typing:

# /etc/init.d/init.crs stop

Then disable CRS by typing:

# /etc/init.d/init.crs disable

on each node. This step prevents the cluster software from starting automatically

when you restore the file /etc/inittab.

2. Save Critical Files

As user root, change directory to /. Using the tar command, create a

compressed archive of /etc, the home directory of the user who installed Oracle,

and all Oracle-specific files and directories. For example:

# cd /

# tar –cvjf oracle-bak.tar.bz2 etc home/oracle

opt/ORCLfmap opt/oracle usr/local/bin/oraenv

usr/local/bin/dbhome usr/local/bin/coraenv

var/spool/cron/oracle

Substitute the actual path of the home directory of the user who installed Oracle,

if is not /home/oracle. If you do not store important files in that directory, you

can omit it from the archive.

The file /var/spool/cron/oracle is a crontab file that might not exist on your

system. If you did not install any optional Oracle components, such as

Automatic Storage Management (ASM), /opt/oracle/ might not exist on your

system.

Copy oracle-bak.tar.bz2 either to removable media or to a location that will not

be overwritten, such as an NFS file system. As a precaution, you might want to

verify the archive at this time, to ensure you have all the files you need. The

command to list the contents of the archive is:

1 2 3 4 5 6 7 8 9 10 11 12
