Uwagi

sp_adjustpublisheridentityrange is used in all types of replication.

For a publication which has the auto identity range enabled, the Distribution Agent or Merge Agent is responsible for automatically adjusting the identity range in a publication based on its threshold value. However, if for some reason the Distribution Agent or Merge Agent has not been run for a period of time, and identity range resource have been consumed heavily to the point of threshold, users can call sp_adjustpublisheridentityrange to allocate a new range of values for a Publisher.

When executing sp_adjustpublisheridentityrange, either publication or table_name must be specified. If both or neither are specified an error is returned.

Permissions

Only members of the sysadmin fixed server role or db_owner fixed database role can execute sp_adjustpublisheridentityrange.
