Apply any kernel customizations required at your site and reboot, if necessary.

If you need to use the Oracle VLM option to create a very large buffer cache or

to use the hugetlb feature of the RHEL3 kernel, see the January, 2004 article

Upgrading from Red Hat Enterprise Linux 2.1 AS To Red Hat Enterprise Linux

and OracleMetaLink document 262004.1, Configuring RHEL 3 and Oracle 9iR2

with Hugetlb and Remap_file_pages. (The latter article applies to Oracle

Database 10g as well as Oracle9iR2.)

If necessary, re-configure raw partitions, as described in the “Pre-installation

Tasks” chapter of Oracle Database Installation Guide.

If necessary, install and configure the ASM library driver software, as described

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

If you are using RAC, load the hangcheck timer:

# /sbin/insmod hangcheck-timer hangcheck_tick=30

hangcheck_margin=180

Install any custom software required at your site.

6. Re-Create the Oracle Environment

Now restore the files you saved in your tar archive. Do not extract the archive

while your current directory is the root directory, or you will overwrite RHEL3

system files. Instead, copy oracle-bak.tar.bz2 to a convenient directory on your

system, such as a user’s home directory. Then become root and extract the

archive into that directory. For example:

$ cd $HOME/tar_dir

$ su

# tar –xvjf oracle-bak.tar.bz2

You can copy most of the files directly from the extracted archive to the RHEL3

directories. You should inspect and merge some files, however, rather than

copying them directly, because of differences between the default RHAS2.1 and

RHEL3 files. Before merging files, review the Linux sections of the “Pre-

Installation Tasks” chapter in Oracle Database Installation Guide: 10g Release

1 (10.1) for UNIX Systems: AIX-Based Systems, hp HP-UX, hp Tru64 UNIX,

Linux, and Solaris Operating System (SPARC) Part No. B10811-02.
