Oracle Enterprise Linux (OEL) 5 or Red Hat Enterprise Linux (RHEL) 5
Important:
Ensure the Known Issues at the bottom of this document is reviewed before proceeding with the installation steps.

OEL 5 and RHEL 5 Known Issues

1. The following packages (or later versions) must be installed on your Linux x86 or Linux x86-64 system:

binutils-2.16.91.0.5-23.4
gcc-4.1.0-28.4
gcc-c++-4.1.0-28.4
glibc-devel-2.4-31.2
libgcc-4.1.0-28.4
libstdc++-devel-4.1.0-28.4
libstdc++-4.1.0-28.4
make-3.80-202.2
compat-db 4.1.25-9

Note:
The Oracle Application Server 10g is a 32-bit application to be installed on either Linux x86 or Linux x86-64. These are 32-bit installation requirements on Linux x86-64 in order allow compatibility with the 32-bit Application Server product. Please see the Installation Guide for more details on the Linux x86-64 and other general requirements. This Note does not replace the Installation Guide, as its only stating the newer and specific OEL5/RHEL5 requirements.
Additionally, the following 2 rpms are also being checked in the Patch 7391242 and Patch 7391245 (as part of an installation step stated below). These packages are needed only if you are later planning to install Middle Tier components like Forms & Reports from Oracle Application Server 10g Release 2 (10.1.2.0.2). If you are not planning to install these middle tier components later on this same machine, you can skip the pre-req check warning during installation by manually clicking the check box for the pre-requisite warning dialog and proceeding with the install.

2. Ensure that libXp has been installed. The package libXp was not installed in RHEL 5/OEL 5 with default RPM packages, so it will need to be installed manually. In RHEL 4 this file was provided by the package xorg-x11-deprecated-libs which is installed with default package installation but this is not the case for RHEL5/OEL5 and is now provided with a different rpm, the libXp rpm. Install the package libXp by the command:

# rpm -ivh libXp..i386.rpm

Note: libXp.so.6 can be found by installing the package /Server/libXp-1.0.0-8.1.el5.i386.rpm under Disk3 of the OEL5 media.

Issue the following to confirm:

% rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep libXp

[ Reference Note 443617.1 ]

3. When installing Oracle Identity Management 10g (10.1.4.0.1) within the OEL 5.x or RHEL 5.x operating systems, you will need to create the following symbolic link as root prior to doing any installations:

# ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2

If an error occurs stating that libdb.so.2 already exists, it may be from a previous installation. In this case, either move the file for backup and create the symbolic link or skip this step to see if the following problem occurs.
Without this symbolic link, httpd will give the following error:

httpd: error while loading shared libraries: libdb.so.2:
cannot open shared object file: No such file or directory

With this link in place, httpd should start up successfully in OEL 5.0 or RHEL 5.0

4. Before installing Oracle Application Server Metadata Repository Creation Assistant (MRCA) 10g (10.1.4.0.1), apply Patch 7391245 in order to start the installer. If you do not apply this patch, pre-req check for the OS Version will fail when you invoke the runInstaller.

Before installing Oracle Identity Management 10g (10.1.4.0.1), apply Patch 7391242 in order to start the installer. If you do not apply this patch, pre-req check for the OS Version will fail when you invoke the runInstaller.

5. Follow all other instructions from the Installation Guide and Release Notes and the below Known Issues for OEL 5 and RHEL 5.

6. After initial installation successfully completes, apply the Oracle Identity Management 10g, Patch Set 2 (10.1.4.3.0) - Patch 7215628. This is required in order to be fully certified on OEL 5.x or RHEL 5.x.

OEL 5 and RHEL 5 Known Issues

1. During the installation of Oracle Identity Management 10g (10.1.4.0.1) or Oracle Application Server Metadata Repository Creation Assistant 10g (10.1.4.0.1), you may receive an error regarding the check for display colors:

Could not execute auto check for display colors using command/usr/X11R6/bin/xdpyinfo.
Check if the DISPLAY variable is set.
Checking if CPU speed is above 300 MHz.
Actual 3391 MHz Passed.
Some optional pre-requisite checks have failed (see above).
Continue? (y/n)

Solution:
This prerequisite check can be ignored.

2. During the base install of 10.1.4.0.1 and the patchset install of 10.1.4.3, you may receive a warning message during the installation:

"The OPMN Process Manager failed to start. Please check the logs in the ORACLE_HOME/opmn/logs directory for the cause of failure. Once the cause of failure has been remedied, start OPMN manually and click Retry."

This is a false message and you can click "Ignore" to proceed further with the installation.

3. Simplified Chinese and Traditional Chinese fonts are missing in OEL 5 with update levels less than 3 (OEL5.3). On this level, the product in Simplified Chinese and Traditional Chinese language can not be accomplished without a specific package installed.

Solution:
If you have an OEL5 version with update level 2 or lower, install the following package:

fonts-chinese-3.02-12.el5.noarch.rpm
