When copying the contents of a directory, remember to copy files and directories

with names that begin with ., such as .ssh. and .profile. Use the following

command to list them:

ls –a

b. Symbolic Links

The rc.2, rc.3, and rc.5 subdirectories of /etc/rc.d contain symbolic links to files

under /etc/init.d. Oracle Universal Installer created some of the files and links in

your extracted RHAS2.1 archive. For example, the installer might have created a

file called init.crs under /etc/init.d, with symbolic links named K96init.crs and

S96init.crs in the subdirectories of /etc/rc.d. In addition to copying the files to

/etc/init.d, you must copy these links so that certain Oracle processes can be

started and shut down cleanly on system startup and shutdown. By default, the

cp command copies the files that the links point to, not the links themselves. To

copy the links, use the --no-dereference option with the cp command.

For example (using bash) :

# for DIR in rc2.d rc3.d rc5.d; do

> cd $HOME/tar_dir/rc.d/$DIR

> cp --no-dereference *init.crs /etc/rc.d/$DIR

> done

If you did not install RAC on your RHAS2.1 system, you would replace *init.crs

with *init.cssd in the command line to copy the links. If you have other Oracle-

related links to files in init.d, you would copy them in the same manner.

c. Files to Merge

The following files have changed between RHAS2.1 and RHEL3:

/etc/csh.*

/etc/profile

/etc/group

/etc/passwd

/etc/inittab*

Use the diff command to compare the two versions. For example:

$ diff $HOME/tar_dir/etc/inittab /etc/inittab

If you want to use the RHEL3 version of a file, first back up the RHEL3 file,

then locate the Oracle-specific lines in the RHAS2.1 file and cut and paste those

lines into the RHEL3 file, using a text editor such as vi.

Instead of modifying /etc/group and /etc/passwd directly, you might find it easier

to simply use the groupadd and useradd commands as described in the

“Pre-Installation Tasks” chapter of the Oracle Database Installation Guide. Set
