the same mutex group or from different groups. The following examples describe how
you might use mutex groups to activate and deactivate multiple services.
Example 1—Multiple mutex services of the same mutex group
Service Manager activates the multiple mutex services, which are in the same group,
then deactivates all previously existing services that are also members of that mutex
group. Active services that are members of different mutex groups are unaffected.
Example 2—Multiple mutex services of different mutex groups
Service Manager activates the mutex services, which are members of different mutex
groups. Service Manager then deactivates all previously existing services that are
members of the same mutex groups as any of the newly activated services. Active
services that are members of different mutex groups are unaffected.
To configure and enable a mutex service, you complete the following steps:
Create the new service definition and configure the service as a member of a mutex

group.
When you create the service definition, include the following service attribute in the
service definition, where groupIndex identifies the mutex group for this service. The
groupIndex can be a number in the range -1 to - 2147483647 or 1 to 2147483646. If
the groupIndex is outside of the acceptable ranges, or if you do not include the
mutex-group statement, the service is not included in a mutex group.
