Upon job submission with the -G option and when user groups have overlapping members, defines whether only the specified user group’s limits (or those of any parent group) are enforced or whether the most restrictive user group limits of any overlapping user/user group are enforced.
If the value is Y, only the limits defined for the user group that you specify with -G during job submission apply to the job, even if there are overlapping members of groups.
If you have nested user groups, the limits of a user's group parent also apply.
View existing limits by running blimits.
If the value is N and the user group has members that overlap with other user groups, the strictest possible limits (that you can view by running blimits) defined for any of the member user groups are enforced for the job.
If the user group specified at submission is no longer valid when the job runs and ENFORCE_ONE_UG_LIMIT=Y, only the user limit is applied to the job. This can occur if the user group is deleted or the user is removed from the user group.
