Exalogic 2.0.1 Tea Break Snippets - Scripting Asset Creation

So far in this series we have looked at creating asset within the EMOC BUI but the Exalogic 2.0.1 installation also provide the Iaas cli as an alternative to most of the common functionality available within EMOC. The IaaS cli interface provides access to the functions that are available to a user logged into the BUI with the CloudUser Role.

As such not all functionality is available from the command line interface however having said that the IaaS cli provides all the functionality required to create the Assets within a specific Account (Tenure). Because these action are common and repeatable I decided to wrap the functionality within a simple script that takes a simple input file and creates the Asset.

Following the Script through will show us the required steps needed to create the various Assets within an Account and hence I will work through the various functions within the script below describing the steps.

You will note from the various steps within the script that it is designed to pause between actions allowing the proceeding action to complete. The reason for this is because we could swamp EMOC with a series of actions and may end up with a situation where we are trying to action a Volume attached before the creation of the vServer and Volume have completed.[Read More]

Exalogic 2.0.1 Tea Break Snippets - Importing Public Server Template

Before we can create Virtual Servers within Enterprise Manager Ops Centre (EMOC) we will need to import an appropriate Server Template that will be used to create the Virtual Server. Server templates are associated with accounts and hence may be imported on an account by account basis or for common base templates we can import them once and make them Public. Once we have configured the imported template to be Public it will be available to all accounts and users.

Serve templates can be uploaded to an account in 3 simple steps although this initial upload will make the template private to an account its properties can be set to public by simply changing the "Public" flag within the account Server Template tab. The following steps are required to import a template and make it public.

Exalogic 2.0.1 Tea Break Snippets - Creating Accounts

Once we have created our Users and Networks we will want to enable the Virtual Data Centre (vDC) for access by the Cloud Users. To facilitate this we will need to create Accounts within the vDC / Cloud and allocate the users to these accounts. Once a Cloud User has been allocated to an account they will be able to access that account and hence create / manage Virtual Servers within that account / Pool.

To create an Account within a vDC / Pool you will need to be logged into Enterprise Manager Ops Centre (EMOC) with the appropriate Role, and this is generally done using you Cloud Administrator, then simply navigate to the vDC Management Accordion, vDC, your Cloud and finally Accounts.

Exalogic 2.0.1 Tea Break Snippets - Allocating Static IP Addresses

By default once a Network has been created within the Enterprise Manager Ops Centre (EMOC) it can be allocated to vServers during their creation. At this point an IP Address will be allocated automatically from the pool of Allocated IPs associated with the Network and Account combination.

In many customer solutions the vServers will need to be allocated a specific IP address so that they can be accessed externally at a know location. To achieve this we must Allocate a number of vIPs within the range allocated to the Account. This is done on an Account by Account basis as follows.

Exalogic 2.0.1 Tea Break Snippets - Creating Networks

In the majority or Real World scenarios we will need to access the Virtual Servers running within the Exalogic from an external client network. To facilitate this we will want to leverage the 10Gb Ethernet connection and hence we will need to create 1 or more EoIB networks that can be accessed by the Virtual Servers.

During the installation of the Exalogic 2.0.1 Virtual environment we create a single "EoIB-external-mgmt" network that we could, in theory, use to access the Virtual Servers we create. Although this is possible, assuming it has enough IP Address, this would be bad practice because this network is intended solely for management functionality and access to the Control VMs. Therefore to provide the Virtual Servers with external Ethernet access we will need to create additional EoIB interfaces. Each of these will need to be VLAN tagged to provide network isolation and partitioning.

Exalogic 2.0.1 Tea Break Snippets - Creating Cloud Users

Creating Cloud Users and Administrators will be one of the first tasks when setting up a new Exalogic 2.1 environment. We will step through the simple process of creating users and describe a few key user types. Initially we will need to login as either the root user or the exl-admin user.

Before adding users to the Exalogic 2.1 environment they must exist as either local users on the physical machine running the Exalogic Control Virtual Server or existing within an appropriate repository, LDAP etc, used by the machine for authentication. This is required because Enterprise Manager Ops Centre 12c (EMOC) does not store any account authorisation information instead this is left tot he underlying OS. It is assumed within this blog that this has been done.

Enterprise-class SOA on Exalogic... what, why and how?

At the Oracle Open World 2011 conference, I had presented a session titled "Enterprise-class SOA on Exalogic" along with Vikas Anand and Manas Deb. Exalogic is part of Oracle's new breed of engineered systems, and is geared towards the middleware space. For those new to the term, an 'engineered system' is one where a single vendor provides everything from hardware, network, OS, middleware, applications, etc in one appliance. The hardware and software are fully integrated out of the box and designed for... read more

Configure IPoIB on Solaris 10 branded zone

Compute nodes in Exalogic communicate with each other and mount their shares from the ZFS storage appliance over the bond0 interface. Bond0 is a highly available network interface over the InfiniBand fabric using a portability layer called IPoIB that allows compute nodes and the storage appliance to communicate using TCP/IP protocol over InfiniBand.

In previous entry, we have created a Solaris 10 branded zone, obviously we would also like the branded zone to be able to mount shares from the ZFS storage appliance over IPoIB.

In this entry, I’ll show you the steps.

Create Solaris 10 Branded Zone on Exalogic

One of the reasons that customers choose to run Solaris 11 Express on Exalogic is the capability to create container. Container is a form of Operating System Virtualization that allows multiple operating system environments to coexist on a single system. Container not only allows user to run the same version of Solaris but it is also possible to create a container, also known as branded zone, to run previous Solaris version, such as Solaris 10. It is a very useful feature that enable customer to continue running applications that only certified on older OS version.

In this entry, I will show you the steps to create a Solaris 10 branded zone on Exalogic.
