Accelerate your Oracle DB startup and shutdown using Solaris 11 vmtasks

last week I co-presented the Solaris 11.1 new features at the Solaris user group
I would like to thank the organizers and the audience
You can find the slide deck here
I presented the following Solaris 11.1 new features:


1. Installation enhancement adding iSCSI disks as boot device and Oracle Configuration Manager (OCM) and Auto Service Request (ASR) registration during operating system installation

2. New SMF tool svcbundle for creation of manifests and the brand new svccfg sub-command delcust

3. The pfedit command for secure system configuration editing

4. New logging daemon rsyslog for better scalability and reliable system logs transport

5. New aggregation option for the mpstat , cpustat and trapstat commands in order to display the data in a more condensed format

6. Edge Virtual Bridging (EVB) which extends network virtualization features into the physical network infrastructure

7. Data Center Bridging (DCB) which provides guaranteed bandwidth and lossless Ethernet transport for
converged network environments where storage protocols share the same
fabric as regular network traffic

8. VNIC Migration for better flexibility in network resource allocation

9.  Fast Zone updates for improved system up-time and short system upgrades

10. Zones on shared storage for a faster Solaris Zones mobility

11. File system statistics for Oracle Solaris Zones for better I/O performance observability

12. Oracle Optimized Shared Memory



The Solaris 11 feature that got the most attention was the new memory process called vmtasks.

This process accelerates shared memory operation like : creation locking, and destruction.
Now you can improve your system up-time because your Oracle DB startup and shutdown are much faster.

Any application that needs fast access to shared memory can benefit from this process.

Oracle VM for SPARC (LDoms) Live Migration

This document provides information how we can increase application
availability by using the Oracle VM Server for SPARC software
(previously called Sun Logical Domains).

We tested the Oracle 11gr2 DB on a SPARC T4 while migration the
guest domain from one SPARC T4 server to another without shutting down the
Oracle DB.

In the testing the Swingbench OrderEntry workload was used to
generate workload, OrderEntry is based on the oe schema that ships
with Oracle 11g.

The scenario includes the following characteristic :
30GB DB disk size with 18GB SGA size, The number of
workload users were 50 and the time between actions taken by each
user were 100 ms.


The paper shows the complete configuration process, including the
creation and configuration of guest domains using the ldm command.
In addition to that Storage configuration and layout plus software requirements that
were used to demonstrate the Live Migration between two T4 systems.
