Exalogic Networking Part 1

This is the first blog entry in a series I will be writing on Exalogic Networking. The entries will start with the low level basics and work their way up to architectural strategies for the partitioning and configuration an Exalogic Rack.

This first entry will look at the low level creation and configuration of vNICs, vIPs, vLANs, BONDs and how we can leverage scripting and the dcli command to configure all Exalogic Compute Nodes at the same time. At this point in time the scripts with documented within this page are designed from Oracle Enterprise Linux but can be tweaked slightly for a Solaris Exalogic installation. In addition we will focus on the external facing 10Gb network because the the 1Gb is management only and should be on a private network whilst the internal InfiniBand network will not be directly accessible to the outside world.

Java CAPS Tip : Configuring SJSAS For MSMQ XA Transactions

Following on from my MSMQ blog entry, "Reading MSMQ Messages with high TPS",  I was required to reproduce the scenario running in a SJSAS 8.2 Environment. Since this is not the standard Java CAPS 5.1.3 Runtime Application Server we need to configure is specifically to work with the appropriate queue systems. Although a number of documents exist informing you how to do this the key information does not exist at present in an online format. So I have decided to put this entry together based on a number of the engineering documents so that I can easily access the information when required.[Read More]

Java CAPS Tip : Application Reconfiguration

Following on from my previous blog entry on Reconfiguring Java CAPS EARs I will expand on the functionality available within the Java CAPS 5.1.x iConfigure Tool and how it can be used to reconfigure a deployed EAR file. Then I will compare this with, its evolutionary successor, within Java CAPS 6 configuration utility. Although at present there is no migration tool to move the iConfigure xml files information to the new property structure this would be an interesting sideline project for when I have some free time.

Java CAPS Tip : Reconfiguring Java CAPS EAR Files

Given the new reconfiguration functionality available within the Java CAPS 6 release you may be wondering why this type of functionality is not available within the previous releases of the tool set. Well their is a little known, undocumented, tool that is available from Sun Java CAPS support called iConfigure. The iConfigure tool will allow you to take an existing 5.1.x ear file and change its configuration based on a supplied, delta, XML configuration file. As a result of this you can now redeploy and reconfigure you Java CAPS 5.1.x EAR file without needing to rebuild that EAR within Enterprise Designer.

My intention within a future blog entry (Java CAPS Application Configuration) is to describe to people already using the iConfigure tool how they can successfully migrate their configuration information from their XML file to the Java CAPS 6 properties based implementation thus facilitating ease of migration.
