Example on how to add Virtual Host On em12c

Posted on June 12, 2013December 23, 2018 by Osama Mustafa in Application

Active/Passive Clusterware , how to use it with em12c ? How to monitor OS and Database ? As One Single host Agent will deploy on Both Hosts without Any problem but in this case you will only Deal with one Host as Single not as Clusterware.

i will provide example how to add active/passive Clusterware to em12c :

First Agent should be deploy for single Host not acitve/passive clusterware, after do that Run the below command from Single Host

emctl deploy agent -o -n “Service_name” -A

The Below Commands should be run from new agent Location

emctl secure agent

emctl start agent

emctl config agent addinternaltargets

**I prefer to set Service_name —> OracleAgent12cShared.

** Re run the above command on the passive Node after Failover shared storage on it.

Thank you

Allow users Login Solaris 11

Posted on June 3, 2013December 23, 2018 by Osama Mustafa in Operating system

Solaris 11 is the most amazing Platform that you can deal with , Specially if you want to install any Oracle products. you don’t need to check anything before install.

By default root login on solaris disabled and you cannot login as root. ( which is amazing for security ) but sometimes you need to enable this login and to do that follow the below steps :

after login to privileged user can access on Solaris switch user to root.
vi etc/user_attr

#
# The system provided entries are stored in different files
# under “/etc/user_attr.d”. They should not be copied to this file.
#
# Only local changes should be stored in this file.
# This line should be kept in this file or it will be overwritten.
#
oracle::::type=normal;project=user.oracle;defaultpriv=basic,net_privaddr

type should be normal.

and to enable SSH for root user you have to do the following :

vi /etc/ssh/sshd_config
PermitRootLogin = yes

vi /etc/default/login
#CONSOLE =/dev/login|console

rolemod -K type=normal root

Thank you
