Configuring Limited/Full Membership of Exalogic Guest vServers on the Default IPoIB Network (Doc ID 1908498.1)

Last updated on JULY 11, 2016

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.6.0.0 and later
Linux x86-64
Oracle Virtual Sever (x86-64)

The procedure in this document is applicable to v2.0.6 and v2.0.4 Exalogic Guest vServers, running on EECS v2.0.6.0.0 or higher in a virtualized configuration.

Goal

Overview

When vServers are provisioned on the IPoIB default network, they are created, by default, with full membership on the network. When such vServers are created in different accounts within a vDC, due to their full membership, vServers provisioned in Account A can be reached from those provisioned in Account B. Currently, there is no support for changing the membership on the default IPoIB network during the process of vServer creation.

A set of scripts is provided with this document to enable the toggling of vServer membership on the default IPoIB network from full to limited. These scripts can be used to toggle the membership of Exalogic Guest vServers on  the default partition if the vServers have an interface defined on that partition, and also provide support to verify whether the membership changes have been made successfully.

In one execution of the script, Guest vServers belonging to a single account can be modified. To change the membership of Guest vServers belonging to other accounts, the script needs to be executed once for each account.

Note

The scripts may be used for the following operations as well:

  • Changing the membership from limited to full
  • Changing the membership of a subset of vServers in a given account

 

Important: Guest vServers are rebooted as part of script execution for the membership changes to take effect. It is recommended that this procedure be performed during a maintenance window.
