Using Powershell to execute DBCC CheckDB from SQL Agent.

Question

So, I have a weird situation that I think is tied tot he resource group and powershell, but I am having trouble determining if it is that or not. I run DBCC CheckDB using a resource pool and a secondary account. The account has permissions to do the work
and if I log onto the server and run the procedure locally it runs fine in the resource pool configuration. However, when I kick it from the SQL Agent job using the powershell step, it only does checkDB on the first 3 system databases and then stops once it
hits a user database. I am not seeing any errors or messages, it just stops. I ran profiler and I see it do the work, get to the first user database, issues this statement from DBCC, then just stops, and the job ends.
SELECT @BlobEater = CheckIndex (ROWSET_COLUMN_FACT_BLOB)
FROM { IRowset 0xD0936A7902000000 }
GROUP BY ROWSET_COLUMN_FACT_KEY
>> WITH ORDER BY
  ROWSET_COLUMN_FACT_KEY,
  ROWSET_COLUMN_SLOT_ID,
  ROWSET_COLUMN_COMBINED_ID,
  ROWSET_COLUMN_FACT_BLOB
OPTION (ORDER GROUP)
 I am not doing anything special in my code that would limit which databases to process. As I said earlier, executing the call to the procedure from a query window runs as expected and processes all of the databases.
Here is the Agent Code calling powershell:
[string] $DayOfWeek = ""
$DayOfWeek = (get-date).DayOfWeek.ToString()
$DayOfWeek
if ($DayOfWeek -eq 'Sunday')
invoke-sqlcmd -database sysadm -serverinstance HQIOSQLDEV01\DEV01 "exec ConsistencyCheck.upConsistencyCheck NULL, 'N', 'Y', 'N', 'N', 'N'"
else
invoke-sqlcmd -database sysadm -serverinstance HQIOSQLDEV01\DEV01 "exec ConsistencyCheck.upConsistencyCheck NULL, 'Y', 'N', 'N', 'N', 'N'"

Answer 1

There are 3 additional databases. The last known good is today as I am able to execute the procedure via query window just fine. It is only when executed from a SQL Agent job as above that it stops after only doing the System Databases. The largest database
is 130GB in size, with the largest table being 62 GB.
