  Hello SSC,

  Does changing ownership of an object require an instance reset, or can it be done live without causing any problems? (maintenance plans, databases, agent jobs, etc.)  I want to change the owner domain\user to 'sa' on hundreds of servers but need to make sure it won't cause any problems.  These would be SQL Server 2008 and up.

  Thanks,
  Dan

  changing the owner for object or jobs are just  object level schema lock; no instance wide affects. if someone is connecting or updating , you might have to wait for a transaction to complete, but it's just a wait.

  i use ALTER SCHEMA {schemaname} TRANSFER dbo.TableName all the time, in a loop, as i move data in and out of schemas.

  also i wrote this snippet to identify potential offenders:
  

  --check all databases
select
 'Database Not owned by sa' As Issue,
  name,
  suser_sname(dbz.owner_sid) As TheOwner ,
  CASE
  WHEN suser_sname(dbz.owner_sid) <> 'sa'
  THEN 'ALTER AUTHORIZATION ON DATABASE::' + name + ' to sa;'
  ELSE ''
  END As cmd
from sys.databases dbz
WHERE suser_sname(dbz.owner_sid) <> 'sa'
order by dbz.name;

  IF OBJECT_ID('tempdb.[dbo].[#tmp]') IS NOT NULL
DROP TABLE [dbo].[#tmp]
CREATE TABLE [dbo].[#tmp] (
[DatabaseName] NVARCHAR(128)        NULL,
[AsObjectName] SYSNAME         NOT NULL,
[ObjectType]  NVARCHAR(60)         NULL)

  INSERT INTO #tmp([DatabaseName],[AsObjectName],[ObjectType])
EXEC sp_msForEachDb 'SELECT ''[?]'' As DatabaseName, name AsObjectName, type_desc AS ObjectType FROM [?].sys.objects WHERE principal_id IS NOT NULL'

  SELECT 'object not owned by sa' AS Issue,* FROM #tmp

  SELECT
  'objects not in dbo schema' As issue,
  sch.[name] AS schema_name,
  objz.[name] AS table_name,
  'ALTER SCHEMA dbo TRANSFER ' + quotename(sch.[name]) + '.' + quotename(objz.[name]) + ';' AS cmd
FROM
  sys.objects AS objz JOIN
  sys.schemas AS sch
   ON objz.[schema_id] = sch.[schema_id]
WHERE sch.schema_id > 4
