RHEL6 64-bit and Oracle 11g R2

ok so RH Enterprise Linux 6 has been released. I'm installing it to test an oracle 11g installation. included below is the kickstart script used.

BIG CAUTION: ORACLE 11g (nor any other oracle versions afaik) is not certified (yet) to run on RHEL6. SO DON'T PUT THIS ON PRODUCTION.

first issue encountered is the installation over NFS. my NFS RHEL6 sources are on anAIX 5L machine. and anaconda won't mount the export.

i resorted to using an RHEL5U5 system to host the ISOs.

here's the directory structure:

/apps/erik/RHEL6/

|-- i386
|   |-- images
|   |   |-- README
|   |   |-- TRANS.TBL
|   |   |-- install.img
|   |   |-- product.img
|   |   `-- pxeboot
|   |-- rhel-server-6.0-i386-dvd.iso
|   |-- rhel-server-supplementary-6.0-i386-dvd.iso
|   `-- sha256sum.txt
`-- x86_64
    |-- images
    |   |-- README
    |   |-- TRANS.TBL
    |   |-- efiboot.img
    |   |-- efidisk.img
    |   |-- install.img
    |   |-- product.img
    |   `-- pxeboot
    |-- rhel-server-6.0-x86_64-dvd.iso
    |-- rhel-server-supplementary-6.0-x86_64-dvd.iso
    `-- sha256sum.txt

the "images" directory is copied from the server iso image. the nfs based installationwon't proceed without that directory. appears to be a mandatory requirement now for the NFS install.

the kickstart install sets an oracle user and needed environment for
an 11g installation. my oracle11g sources are hosted on an AIX 5L machine
(UX0027). installation will be done via vnc session.

the usual nfs mounting procedure won't work. it spits out an error:

mount.nfs   UX0027:/export/isapsys/oracle11g /mnt/nfs   -v
mount.nfs: timeout set for Tue Nov 16 14:36:19 2010
mount.nfs: trying text-based options 'vers=4,addr=UX0027,clientaddr=LX013'
mount.nfs: mount(2): Remote I/O error
mount.nfs: Remote I/O error

the fix is to use v3 or v2 option:

[root@LX0130 ~]# mount.nfs   UX0027:/export/isapsys/oracle11g /mnt/nfs -o v3
[root@LX0130 ~]# ls /mnt/nfs
AIX  AIXclient  Linux64  Linuxclient  linux.x64_11gR1_database_1013.zip
[root@LX0130 ~]#

Installation of Oracle 11g R2

in a vnc session, running runInstaller encountered a permission denied
error due to the mount optins of /tmp:

/dev/mapper/vg00-lvsys05 on /tmp type ext4 (rw,noexec,nodev)

to fix (just for the install)

[root@LX0130 ~]# mount -o exec,remount /tmp
[root@LX0130 ~]# mount | grep /tmp
/dev/mapper/vg00-lvsys05 on /tmp type ext4 (rw,nodev)

install then started but encountered another error during a pre-req
check - there are "missing" packages:

libaio-0.3.105
compat-libstdc++-33-3.2.3
libaio-devel-0.3.105
libgcc-3.4.6
libstdc++-3.4.6
unixODBC-2.2.11
unixODBC-devel-2.2.11
pdksh-5.2.14

these packages are old versions. RHEL6 ships with the following:

libaio-0.3.107-10.el6.x86_64
libaio-0.3.107-10.el6.i686
libaio-devel-0.3.107-10.el6.x86_64
libaio-devel-0.3.107-10.el6.i686
compat-libstdc++-33-3.2.3-69.el6.x86_64
compat-libstdc++-33-3.2.3-69.el6.i686
libgcc-4.4.4-13.el6.x86_64
libgcc-4.4.4-13.el6.i686
unixODBC-2.2.14-11.el6.x86_64
unixODBC-devel-2.2.14-11.el6.x86_64

(these packages will be installed by the kickstart file above).

pdksh is no longer part of rhel6. i did install the following:

ksh-20100621-2.el6.x86_64
mksh-39-4.el6.x86_64

So i chose "Ignore All" and continued the installation. it finished with
no additional complaints.

hth.

update (in reference of comments below from Bob):

i did a re-install. this time with a database created. it proceeded with no problems. haven't tried doing it manually AFTER oracle SW only installation.
