The following sections describe how to do a complete installation of Oracle Virtual Assembly Builder.
Read this section before proceeding. It contains vital security information and precautions. Failure to read and understand these items may cause security vulnerabilities.
The user who installs should be a trusted user, and a member of a trusted OS group.
The template creation process does a security check to see that the Operating System (OS) user attempting to create the template is the same OS user who owns the Oracle Virtual Assembly Builder bin directory. Having the OS user who installs the product be the same OS user who creates templates ensures that the security check will succeed.
Before using Oracle Virtual Assembly Builder, ensure that your environment meets the following prerequisites. These items are not required for installation, but are necessary environmental components for the use of Oracle Virtual Assembly Builder.
The following are requirements for virtual to virtual introspection and deployment.
Note:
Virtual introspection can only be performed on non-Oracle JRockit Virtual Edition deployments.Introspection on a deployed virtual machine (VM) can fail to complete when the temporary directory used for introspection is a mounted NFS share with NFS file locking. To avoid this problem, remount the NFS file system with locking turned off:
mount -o nolock example:/scratch /net/example/scratch
You must ensure that the reference system on the virtual machine has enough space for an image of itself. If this is an issue, you can resolve it by using one of the following options:
Copy System.img to Oracle Virtual Assembly Builder host and run modifyjeos to increase the disk size to handle the snapshot of the product installation. Then redeploy the image and restart it. This will provide enough space in the /tmp directory.
If the previous option is not feasible, mount an NFS disk of suitable size, and place the catalog on it. For remote packaging, use the NFS disk location, rather than /tmp.
In order to deploy your applications into virtualized environments, you must also have appropriate Reference Systems set up (for Introspection), and an Oracle VM environment ready to deploy your applications.
This document details the steps you must complete in order to install and configure Oracle Virtual Assembly Builder. The entire process is comprised of the following steps:
Install and configure your reference systems. Supported reference systems include:

Depending on the type of operating system you choose for your appliance at template creation time, you may need the Oracle Enterprise Linux Base Image or Oracle WebLogic Server on Oracle JRockit Virtual Edition Base Image (or both).
Note:
You have a choice of downloading an Oracle provided sample Oracle Enterprise Linux Base Image, or creating your own. The sample image is available on Oracle Technology Network:
http://www.oracle.com/technology/products/ovab
Ensure that the base image architecture matches your component software. That is, use a 32-bit base image if your component software is 32-bit; 64-bit base image for 64-bit component software.
To create the appropriate Base Image(s):
Oracle Enterprise Linux Base Image, see: http://www.oracle.com/technetwork/server-storage/vm/overview/templates-101937.htmlThe information on this, and referenced pages, will provide the information you need to create your own System Base Image.
When specifying a base image, the image must meet the following requirements:
Oracle Enterprise Linux 5 (UL3+)
At least 250MB of free space for /tmp. (depending on the type of product your are creating appliance for and deploying, you may need more free space. Refer to appropriate product install guide for specific free space requirement)
At least 500MB of swap space
You must have installed the following packages (RPMs):
nc
libaio
zip
unzip
nfs-utils
xen-tool
In addition, for deploying virtual machines for FMW components, you must have installed:
gcc
gcc-c++
setarch
sysstat
libaio
libaio-devel
libstdc++
libstdc++-devel
compat-libstdc++
compat-db
control-center
glibc-common
binutils
make
For deploying virtual machines for Oracle Database, you must have installed:
binutils
compat-libstdc++
elfutils-libelf
elfutils-libelf-devel
gcc
gcc-c++
glibc
glibc-common
glibc-devel
glibc-headers
libaio
libaio-devel
libgcc
libstdc++
libstdc++-devel
make
numactl-devel

soft=4096
hard=4096
For Oracle database, the following shell parameters must be set
nproc-soft=2047
nproc=hard=16384
nofile-soft=1024
nofile-hard=65536
maxproc(ulimit -p)=16384
descriptors(ulimit -n)=65536
For Oracle database, the following kernel parameters must be set:
Semaphore Limits
semmni=128 # max number of arrays; default is 128 semmsl=250 # max semaphores per array. default is 250 semmns=32000 # max semaphores system wide; default is 32000 semopm=100 # max ops per semop call; default is 32
Shared Memory Limits
shmmni=4096 # max number of segments; default is 4096 shmmax=0.5GB # max seg size (kbytes); default is 4194303, which is 3GB shmall=2097152 # max total shared memory (kbytes); default is 1073741824
File Descriptors
file-max=6815744 # system wide file descriptors; default is 204573; aio-max-nr=Maximum:1048576 # default is 65536; ip_local_port_range=9000 65500 # default is 32768 61000; rmem_default=262144 # default is 109568; rmem_max=4194304 # default is 131071; wmem_default=262144 # default is 105968 wmem_max=1048576 # default is 131071
Additional database requirements:
Name Resolution: Ensure that host names are resolved through the /etc/hosts file. Note that this is not what base image can preset.
Add the following line in the /etc/pam.d/login file:
session required pam_limits.so
You must turn on oraclevm-templates while creating the image.
Oracle recommends that you turn off iptables while creating the image.
The base image must have the user oracle. One example of meeting this requirement is to boot the base image, log on to it as root, and call /usr/sbin/useradd oracle.
Note:
The primary group for oracle user must be oracle. By default, when you create the oracle user, it is automatically set. To set it manually, create the group and assign it to oracle user by executing:/usr/sbin/groupadd oracle /usr/sbin/usermod -g oracle -a -G oracle oracle
Refer to your modifyjeos documentation for instructions on creating a base image.
Oracle WebLogic Server on Oracle JRockit Virtual Edition Base Image is included in the Oracle WebLogic Server on Oracle JRockit Virtual Edition bundle. Unzip the product's zip file, and find the system.img and vm.cfg files (in the wlsve sub-directory of the structure into which you unzipped the files).
Note:
The base image (system.img) must not have an executable bit. Otherwise, export/import may not work properly. You must set the permission of base images properly, for example, to 644:
$ chmod 644 System.img $ ls -l System.img -rw-r--r-- 1 jdoe g900 748500480 Apr 22 12:52 System.img
