注解

属性 MaxDistributionRetention 指定删除事务之前的最长保持期。 尚未收到早于最大分发保留期的复制命令的订阅将被标记为非活动状态。

只有MaxDistributionRetention分发数据库上的 或 replmonitor 固定数据库角色的成员db_owner、发布访问列表中的用户 (PAL) 使用分发数据库的发布或对分发数据库中的 MSdistributiondbs 系统表具有 SELECT 权限的用户才能检索属性。

属性 MaxDistributionRetention 只能由分发服务器上的固定服务器角色的成员 sysadmin 设置。

检索 MaxDistributionRetention 属性等效于执行 sp_helpdistributiondb。

MaxDistributionRetention设置 属性等效于执行sp_adddistributiondb或sp_changedistributiondb。
