DB00207W

MULTI-USER UNABLE TO ACTIVATE IUCV SUPPORT

Reason:

The attempt to activate the guest System Control Program (SCP) Inter-User Communication Vehicle (IUCV) support function failed when the Multi-Guest Sharing option was activated.

Action:

Before running Multi-Guest Sharing option applications, stop the Multi-User Facility by executing the EOJ option of the DBUTLTY COMM function or by using the related console command COMM. Then resolve the problem causing IUCV failure (see the following Resolution Procedure), initiate the Multi-User Facility, and try again.

Resolution Procedure:

Begin the process of problem resolution by seeing if the following are true:

  1. The directory control statements that follow are specified in the VM directory for the guest System Control Program containing the Multi-User Facility:

    IUCV ALLOW

    IUCV (MSGLIMIT= subparameter)

    OPTION (MAXCONN= subparameter)

  2. The TASK MUF startup option has the vmnumber parameter specified as greater than zero. For details on the TASK MUF startup option, see the CA Datacom/DB Database and System Administration Guide.
  3. The following DBSYSID macro parameters in the DBSIDPR module are being used by the Multi-Guest Sharing applications:

    VMID= is the target guest SCP containing the Multi-User Facility.

    VMSUBID= is the number for the target Multi-User Facility.

    VMSVC= is the number identifying target Multi-User Facility (not an
    actual SVC number).

  4. You have used the CA? command to see if CA-System Adapter is installed. CA-System Adapter is the name of one of the components of the CA CIS (Common Infrastructure Services).
  5. There is a SET SDL statement for DBGXIPRn,SVA where n is 0, 1, 2, 3, or 4. You will need to check the installation sub-library for DBGXIPR to obtain the correct value for n for the release of CA Datacom you are executing.
  6. All of the partitions (including the MUF partition) have REAL STORAGE available to them. For a formula for determining storage requirements, see the CA Datacom/DB Database and System Administration Guide.

For more information, see the chapter on using CA Datacom/DB in a VM environment in the CA Datacom/DB Database and System Administration Guide.
