A HoBT-level lock does not necessarily lock the aligned HoBTs for the partition. Note HoBT-level locks usually increase concurrency, but introduce the potential for deadlocks when transactions that are locking different partitions each want to expand their exclusive locks to the other partitions.

users in the database as that will prevent acquiring the exclusive lock on the database. This command waits only a short time to acquire the exclusive lock before timing out. If the database is being replicated, stop the replication agents before enabling vardecimal storage format on the data...
