https://rhn.redhat.com/errata/RHSA-2005-412.html

1.1. After installing these patches, run ldconfig -v.
(Note : ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/lib and /usr/lib). The cache is used by the run-time linker, ld.so or ld-linux.so. ldconfig checks the header and file names of the libraries it encounters when determining which versions should have their links updated )

1.2. Verify minimum Kernel Requirements with uname and rpm command,




[root@vision ~]# uname -r
2.6.9-5.ELsmp
[root@vision ~]# rpm -q glibc
glibc-2.3.4-2

1.3. Domain Name System (DNS) Resolver Parameters
Edit the following file /etc/resolv.conf and set the following parameters as below,
options attempts:5
options timeout:15

(Note : The resolv.conf file resides in the /etc directory and contains the IPs of domain name servers that you will probably need if you are going to do anything on the internet.
options :Allows certain internal resolver variables to be modified. The syntax is where option is one of the following
timeout: n (IN SECONDS)
sets the amount of time the resolver will wait for a response from a remote name server before retrying the query via a different name server.
attempts: n
sets the number of times the resolver will send a query to its name servers before giving up and returning an error to the calling application).


1.4. Host names

1.4.1. The format of hosts /etc/hosts file must be formatted as follows :

127.0.0.1 localhost.localdomain
.
(In apps01 hosts file make this entry and there should be entry for the other nodes which hosts the servers)

192.9.200.149 apps01.oneapps.com local_host
192.9.200.146 apps02.oneapps.com

(In apps02 the following entries to the /etc/hosts file has to be added )

192.9.200.146 apps02.oneapps.com local_host
192.9.200.149 apps01.oneapps.com

Ping the remote machine with and hostname and check
Comment the first line in the /etc/hosts file

1.4.2. Verify that the /etc/sysconfig/network file is formatted as follows :
HOSTNAME=.

Exi : HOSTNAME=apps01.oneapps.com

( Note : Make sure that your machines has static ip address)



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

Note: If you changed any files in the previous steps, reboot the system.

1.6. Modify number of open descriptors: in file /etc/security/limits.conf add the following lines:
hard nofile 65535
soft nofile 4096

(.You can protect against certain types of denial of service attacks by modifying /etc/security/limits.conf. This file sets limits on system resources for each user.. The above setting limits the maximum number of files open)

1.7. Change port range value : /etc/sysctl.config add the following line,

net.ipv4.ip_local_port_range = 1024 65000

1.8. Set LD_ASSUME_KERNEL in file /etc/profile

LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL

1.9. Apply one of these OS library patches: 4198954 (for Red Hat 4.0), you can download it from metalink.

 The above patch contains compat_libcwait-2.0-2.i386.rpm, compat-oracle-rhel4-1.0.-5.i386.rpm
 After applying the compat-libcwait-2.0-2.i386.rpm move the libcwait.so - library from /usr/lib to /lib and modify the path in /etc/ld.so.preload

2.0 Create a goup and two users one owner of database and other owner of oracle application

groupadd dba
useradd –g dba –G dba oracle
useradd –g dba –G dba applmgr
passwd oracle
passwd applmgr
