Purpose
-------
This Article Will Assist You To Determine if you are running a
Red Hat Supplied Kernel That Can Be Supported by Both Red Hat and Oracle.
Scope & Application
-------------------
This is intended for Linux System Administrators and Linux DBAS
With sysadmin Skills On Red Hat Advanced Server Version 2.1 (RH 2.1 AS / ES) &
On Red Hat Enterprise Linux (RHEL 3.0).
This Note Is Done for x86 processor architecture.
The Errata Kernel's List is Not Applicable To The Itanium Processor.
How to verify you have a redhat supported kernel
------------------------------------------------
Issue The Following 2 Commands, Then Proceed THROUGH THE BELOW TABLE
To check if your kenel is supported.
1) # uname -a
Example Output:
# uname -a
Linux Linux1 2.4.9-E.3 # 1 fri may 3 17:02:43 Edt 2002 i686 Unknown
The Following Table Details The Currently Supported Red Hat Advanced Server Kernel Versions.
If The Version of the Kernel Shown by Uname Is Not listed The you are running an unsupported kernel.
.
However, Oracle Recommends Use of Redhat Linux Advanced Server 2.4.9-ERRATA 2.4.9-E.12 or Higher.
In Case of Red Hat Enterprise Linux (Rhel) The supported kernel is 2.4.21-4.el or higher

2) The next step is to check to ensure That the the are no tainted modules
Loaded. Some 3rd Party Vendors Distribute Binary Modules Which Are Loaded
INTO The Kernel. Binary Modules Are Modules Where The Source Code Is Not
Available for Linux Developers to InvestiGate. if The are binary modules
Loaded There Is, In Essence, a Kernel Extension That Can Only Be Fixed
By the vendor. as such oracle and red hat cannot full support environments
WHERE Binary Modules Are Loaded.
# / sbin / lsmod
The Header Line from this Command Should Include The Text
'Not tainted' as in The Following EXAMPLE:

If you see the word 'tainted' listed, The This Indicates That The Kernel
Cannot Be Supported. The Values listed by Tainted Area Follows:
P Means That a proprietary binary module is loading That Does Not Contain A
GPL license.
FORCE LOADED. Force loading modules bypass
Kernel / Module Verification Checks.
From kernel.h
#define taint_proprietary_module (1 << 0)
#define taint_forced_module (1 << 1)
#define taint_unsafe_smp (1 << 2)
#define taint_forced_rmmod (1 << 3)
P = taint_proprietary_module
F = taint_forced_module
Here is an example with a proprietary driver loading:
Module Size Used by Tainted: P
NFS 91936 0 (AutoClean)
Lockd 61184 0 (Autoclean) [NFS] SunRPC 86032 0 (AutoClean) [NFS LOCKD]

AdditionAl Information
----------------------
To get the licensing information for the loading kernel modules,
Execute Thase Commands in a Bash Shell Script:
For i in `cat / proc / modules | awk '{print $ 1}'`;
DO
X = `/ sbin / modinfo -n $ i`;
Echo $ x;
Size $ x;
Modinfo -l $ I;
Modinfo -p $ i;
DONE
The resulting Output Will LOOK LOKE:
# / sbin / modinfo hangcheck-timer
Filename: /lib/modules/2.4.9-e.3/kernel/drivers/addon/Hangcheck/hangcheck-timer.o

----
- IF a Customer Is Running An Os That Does Not Fit The Above Needs, WE DO
Support the Oracle Products Itself, We Well Just Defer OS Related
Issues.
- Oracle & RedHat Recommends The Customer To BE on Kernel Version 2.4.9-E.12
OR HIGHER.
