To increase the vdi size issue the following command: D:\VirtualBox VMs\OEL6U3-Developer>"c:\Program Files\Oracle\VirtualBox\VBoxManag e.exe" modifyhd OEL6U3-OS.vdi --resize 51200 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% c:\Program Files\Oracle\VirtualBox\VBoxManage.exe is the Virtual Box exe D:\VirtualBox VMs\OEL6U3-Developer\OEL6U3-OS.vdi is the VDI file 51200 is in MB = 50 GB

Step 1: Install the RPMs which are missing, the following are required as per oracle document: rpm -q binutils-2.20.51.0.2-5.28.el6 compat-libcap1-1.10-1 compat-libstdc++-33-3.2.3-69.el6 compat-libstdc++-33-3.2.3-69.el6 gcc-4.4.4-13.el6 gcc-c++-4.4.4-13.el6 glibc-2.12-1.7.el6 glibc-2.12-1.7.el6 glibc-devel-2.12-1.7.el6 libaio-0.3.107-10.el6 libaio-devel-0.3.107-10.el6 libgcc-4.4.4-13.el6 libstdc++-4.4.4-13.el6  libstdc++-4.4.4-13.el6  libstdc++-devel-4.4.4-13.el6 libXext  libXtst  openmotif-2.2.3  openmotif22-2.2.3  redhat-lsb-core-4.0-7.el6  sysstat-9.0.4-11.el6 uln-internal-setup-1.0.1-1.el6.noarch.rpm The query will result in several rpm saying as unavailable, most of them have a new version so we will be fine. package binutils-2.20.51.0.2-5.28.el6 is not installed package gcc-4.4.4-13.el6 is not installed package gcc-c++-4.4.4-13.el6 is not installed package glibc-2.12-1.7.el6 is not installed package glibc-2.12-1.7.el6 is not installed package glibc-devel-2.12-1.7.el6

1) Install the oracle-validated RPM http://www.oracle.com/technetwork/articles/servers-storage-admin/ginnydbinstallonlinux-488779.html 2) Set user limits vi /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 3)  Edit /etc/pam.d/login and add the line below in order for the login program to load the pam_limits.so so that the /etc/security/limits.conf is read and limits activated and enforced. session required pam_limits.so 4) Add Groups and Users groupadd –g 1000 oinstall groupadd –g 1021 asmdba groupadd –g 1031 dba groupadd –g 1023 oper useradd –u 1101 –g oinstall –G dba,asmdba,oper oracle 5) Create directory mkdir -p /home/oracle/app/oracle chown oracle:oinstall /home/oracle/app/oracle chmod -R 775 /home/oracle/ 6) Create the user profiles for oracle user. su - oracle vi .bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then

vi /etc/fstab /dev/sdb                /home/oracle               ext4 defaults        0 0 /dev/sdc                /home/weblogic             ext4 defaults        0 0 mount –a [root@soadev db]# mount /dev/sdb on /home/oracle type ext4 (rw) /dev/sdc on /home/weblogic type ext4 (rw)
