[siva krishna M2]

Do you know how ServiceNow locks the instance to restrict doing other plugin installations/update set retrieval/ update set implementation during one plugin installations/update set retrieval/ implementation?

ServiceNow creates a record with name "Update-Mutex" in sys_mutex table to lock the instance to restrict doing other plugin installations/update set retrieval/ update set implementation

Kindly click on "Helpful" if it helps

@siva krishna M2 While creating update-mutex record in mutexes table, does system store information on user who is triggering the action of plugin installation/update set retrieval/implementation?
