I tried to run this statement:
alter index [index_name] on [schema_name].[table_name] reorganize
but got an error:
The index "index_name" (partition 1) on table "table_name" cannot be reorganized because page level locking is disabled.
Where can I find an information about page level locking and how to unlock it? This is a part of our nightly job and I got this message for several days in a row.
