Distributed Server Definition

CA VM:Secure implements the product server virtual machine definition as an IDENTITY entry in an SSI complex. This implementation enables the server (usually VMSECURE) to log in to all cluster member systems at the same time. Additional changes in the product server virtual machine definition are as follows:

• Audit minidisks are member-specific and are defined in a SUBCONFIG entry specific to each member.
• The minidisks that are defined for the CP Object Directory area are member-specific and are defined in a SUBCONFIG entry specific to each member.
• The distributed product server virtual machines communicate using APPC protocol over a GLOBAL APPC resource definition. You create the definition by adding an IUCV *IDENT statement to the IDENTITY directory entry.
• A two-phase commit process is used to synchronize changes across the complex. A new LOG minidisk is defined to the product server to record the status of a change while it is in flight.
