Enabling Internet access in OEL 6.4 64 bit

Issue : After installing OEL 6.4 , Internet was not working.

Solution :

Goto System-> Preferences -> Network Connections
Under Wired
                  -> System eth0  (Edit)
Make sure below are checked.
 -> Connect   automatically
-> Available ti all users

Under Tab - Wired (you will see the Device MAC address , Nothing in Cloned MAC address)
MTU would be set by default as automatic (bytes).

 Under Tab - 802.1X Security - Nothing is checked.

Under Tab - IPv4 Settings :
Addess : <Machine-IP>   , Netmask: <IP> , Gateway- <IP>
In DNS Servers - <DNSIP>  , Nothing in Search domains.
Check - Require IPv4 addressing for this connection to complete.
Nothing on Routes button details.

Under Tab - IPv6 Settings  , Method - Ignore

After addind DNS Servers, restart the network services from root user.
You can verify the settings in /etc/resolv.conf file
----------
# Generated by NetworkManager
search vijoraapps.com
nameserver <Above DNS IP>
----------
Also you can verify the entry in /etc/sysconfig/network-scripts/ifcfg-eth0
You will see dns entry now, like.
DNS1=<DNSIP>

$service network restart

And test the internet.

You can ping 4.4.4.4 ( to check network connectivity)
or ping 8.8.8.8  

Other commands:
ifconfig
setup
system-config-network

1.#ifconfig
2.#vim/etc/sysconfig/network-scripts/ifcfg-eth0
3.#vim /etc/resolv.conf

R1213 SSO-OID-LDAP Error oame OAMSSA-20027 Could not get user : username, idstore: EBSIdStore == oam_server1.log

Error ==>

<Mar 17, 2015 5:47:20 AM PDT> <Error> <oracle.oam.user.identity.provider> <OAMSSA-20027> <Could not get user : ledefall, idstore: EBSIdStore, with exception: oracle.security.idm.OperationFailureException: javax.naming.NamingException: LDAP response read timed out, timeout used:2000ms.; remaining name 'cn=adusers,cn=users,dc=vijoraapps,dc=com'.>

Solution :

Collected data using
1) Collect data using - >  oiddiag collect_all=true
2) All OID logs from the time of the Timeout errors
(Oracle_Instance/diagnostics/logs/OID/oid1 or instance name)

OID1 instance you have the following default attributes set:
3000 : orclmaxcc=4
3000 : orclserverprocs=1

Reference Doc: http://docs.oracle.com/cd/E28280_01/core.1111/e10108/oid.htm#ASPER99273
Check out the section labeled "23.3.2 LDAP Server Attributes"
http://docs.oracle.com/cd/E28280_01/core.1111/e10108/oid.htm#ASPER99964

You will notice the chart where orclserverprocs and orclmaxcc is mentioned
For orclserverprocs the recommendation is :orclserverprocs Number of CPU cores
and for orclmaxcc, the recommendation is 10

Another suggestion would be the tuning wizard documented here:
http://docs.oracle.com/cd/E28280_01/core.1111/e10108/oid.htm#ASPER106
