Managing CA VM:Secure in a Single System Image Complex › Distributed Server Definition

Distributed Server Definition

The CA VM:Secure product server virtual machine definition is implemented as an IDENTITY entry in an SSI complex. This allows the server (usually VMSECURE or VMDIRECT) to logon 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 will be defined in a SUBCONFIG entry specific to each member.
• The minidisks defined for the CP Object Directory area are member specific and will be 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 which you define 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.
