This document outlines instructions for migrating an existing Oracle Applications system running on Red Hat Linux to Red Hat Linux 4.0. It applies to the following Red Hat operating systems:

· Red Hat Linux 2.1

· Red Hat Linux 3.0


If you installing a new Oracle Applications Release 11.5.10 system on Red Hat Linux 4.0, do not follow the instructions in this document. Instead, refer to Installing Oracle Applications: A Guide to Using Rapid Install and the appropriate sections of Oracle Applications Installation Update Notes and Oracle Applications Release Notes.

1 Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers. For additional information, visit the Oracle Accessibility Program Web site at

Accessibility of Code Examples in Documentation JAWS, a Windows screen reader, may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, JAWS may not always read a line of text that consists solely of a bracket or brace.

Accessibility of Links to External Web Sites in Documentation This documentation may contain links to Web sites of other companies or organizations that Oracle does not own or control. Oracle neither evaluates nor makes any representations regarding the accessibility of these Web sites.

2 Prerequisites

This section describes the requirements for successfully migrating an Oracle Applications system running on a Red Hat Linux 2.1 or 3.0 operating system to Red Hat Linux 4.0

Required software releases, components, and patch levels

The following table contains the minimum product versions required for using these migration instructions.




Oracle Applications


Release 11.5.10 + CU1 is recommended. See Oracle Applications Release 11.5.10 Maintenance Pack Installation Instructions on OracleMetaLink (Doc ID: 259484.1).


Release is recommended. See Interoperability Notes: Oracle Applications Release 11i with Oracle9i Release 2 (9.2.0) on OracleMetaLink (Doc ID: 216550.1)


J2SE 1.4*

See Using J2SE Version 1.4 with Oracle E-Business Suite 11i, Release 11.5.9 or Higher on OracleMetaLink (Doc ID: 246105.1)

*Required on Linux versions Red Hat Enterprise Linux 3.0 and higher

3 Migrating the Operating System

This section outlines the tasks required to migrate an operating system from Red Hat Linux 2.1 or 3.0 to Red Hat Linux 4.0.

Migrate to Red Hat Linux 4.0

System upgrades are described in Appendix A of the Red Hat Enterprise Linux Installation Guide, available at . If you need additional information about operating system migrations, contact Red Hat directly.

Install Red Hat packages and apply patches

Migrating to Red Hat Linux 4.0 automatically installs the following packages and patches:


In addition, you must install openmotif21-2.30-11 and libaio-0.3.102-1 manually. These two packages are available on Disk 3 of the RHEL4.0 media.

To finish the installation, complete the following steps.

1. Verify that all packages and patches are present in your system, use the rpm -qa|grep command. For example, to verify that all compat-gcc packages are present, you would type the following command, and it would return the associated components.

2.            # rpm -qa|grep compat-gcc
3.              compat-gcc-32-c++-3.2.3-47.d
4.              compat-gcc-32-3.2.3-47.3

6. Apply OS library patch 4198954 to supply two additional rpm commands, which provide compatibility files that are necessary for running Oracle on Red Hat Linux 4.0. See the readme file in the patch for more information.

To install the rpms, use the following commands:

rpm -ihv compat-oracle-rhe14-1.0-5.i386.rpm
rpm -ihv compat-libcwait-2.0-2.i386.rpm

Refer to the release notes for the Oracle products you are installing or running.


This rpm checks for the xorg-x11 -deprecated-libs and xorg-x11 -deprecated-libs-devel packages. If they are not installed, get them by selecting X Software Development on the Add Remove Software screen during the RH 4.0 installation.

7. Reboot your system.

8. Apply Oracle9i (Release 2) interoperability patch 3119415 to the RDBMS ORACLE_HOME.

9. Apply Oracle 8.1.7 Applications interoperability patch 3846086 to the iAS ORACLE_HOME.

10. Apply Oracle 8.0.6 patch 3293983 and Discoverer patch 3170128 to the 8.0.6 ORACLE_HOME.

4 Post-migration Tasks

Finish the migration to Red Hat 4.0 by performing all the tasks in this section.

Set DNS parameters

Two Domain Name System (DNS) resolver parameters (timeout and attempts) are set by default to low values when the operating system is installed. These values may cause attempts to make network connections to an Oracle database to fail.

If a connection attempt fails, re-set the DNS parameters in the /etc/resolv.conf file on each server node to the following values:

options attempts:5
options timeout:15

Modify host names

Modify the following settings for host names:

1. Verify that the /etc/hosts file is formatted as follows:

2.   localhost.localdomain
3.             .

5. Verify that the /etc/sysconfig/network file is formatted as follows:

6.            HOSTNAME=.

8. If the /etc/sysconfig/networking/profiles/default/network file exists, remove it.

9. Reboot the system if you make changes to any of these files.

Modify number of open file descriptors

Open /etc/security/limits.conf and change the existing values for "hard" and "soft" parameters as follows:

hard nofile 65535
soft nofile 4096

Modify port range value

Open /etc/sysctl.conf and change the port range value as follows. Reboot the system after you make this change.

net.ipv4.ip_local_port_range = 1024 65000

Set environment

Set the environment as follows before you start the Applications:

1. Use the following command to verify the host name setting. It should return a fully qualified host name (for example: .).

2.            # hostname

4. Use the following command to install rpm setarch-1.0-2 (or higher) for the hugemem kernel. You can omit this step for up, smp, and book kernel:

5.            # setarch i386

Set LD_ASSUME_KERNEL environment variable

This value must be set correctly so that Java will work. You must also make the value permanent by entering it in the applmgr user and the oracle user shell initialization files (such as $HOME/.bash_profile or $HOME/.profile), or in the system's global shell initialization file (/etc/profile).

From a Bourne, Bash, or Korn shell, type the following:
