the same user and group ID values as in the RHAS2.1 files. Be sure to set a

password for the user who installed Oracle.

Oracle Universal Installer creates copies of /etc/inittab, such as inittab.cssd.

Recreate these by copying the RHEL3 version of /etc/inittab, then cutting and

pasting the Oracle-related changes.

As a precaution, do not add the Oracle-related lines to /etc/inittab until you are

ready to restart Oracle. Instead, make a copy of the RHEL3 version of

/etc/inittab called /etc/new_inittab and add the Oracle-related lines to that file.

d. Kernel Limits

Some default kernel limits changed between RHAS2.1 and RHEL3. For best

results, do not copy the RHAS2.1 sysctl.conf file into /etc. Instead, set kernel

limits as described under “Configuring Kernel Parameters on Linux” in the

Oracle Database Installation Guide. To learn how to set a value for the new

RHEL3 limit hugetlb_pool, refer to the January, 2004 article Upgrading

from Red Hat Enterprise Linux 2.1 AS To Red Hat Enterprise Linux 3 at:

That document also explains how to use the Oracle VLM option to create a very

large buffer cache.

7. Restart Oracle

If you want to take advantage of the asynchronous I/O capability of the RHEL3

kernel, relink Oracle by using the following command line, as the user who

installed Oracle:

$ cd $ORACLE_HOME/rdbms/lib && make PL_ORALIBS=-laio

–f ins_rdms.mk async_on

Frequently

Asked Questions (FAQ) Asynchronous I/O (aio) on Red Hat Advanced Server

Version 2.1 – 3.0.

If you do not need asynchronous I/O, you do not need to relink Oracle.

Now rename /etc/new_inittab to /etc/inittab by typing:

# sync; sync; sync; mv /etc/new_inittab /etc/inittab

On RAC configurations, reboot one node at a time. Verify that each node has

started correctly before starting the next node. For more information, see Oracle
