try this one

1.

check the waits

SELECT * FROM sys.dm_os_wait_stats
WHERE wait_type IN (‘CLR_AUTO_EVENT’, ‘CLR_CRST’, ‘CLR_JOIN’, ‘CLR_MANUAL_EVENT’
, ‘CLR_MEMORY_SPY’, ‘CLR_MONITOR’, ‘CLR_RWLOCK_READER’, ‘CLR_RWLOCK_WRITER’, ‘CLR_SEMAPHORE’
, ‘CLR_TASK_START’, ‘CLRHOST_STATE_ACCESS’, ‘ASSEMBLY_LOAD’, ‘FS_GARBAGE_COLLECTOR_SHUTDOWN’
, ‘SQLCLR_APPDOMAIN’, ‘SQLCLR_ASSEMBLY’, ‘SQLCLR_DEADLOCK_DETECTION’, ‘SQLCLR_QUANTUM_PUNISHMENT’)
ORDER BY wait_time_ms DESC, wait_type ASC;

check the wait type explanation

Wait statistics, or please tell me where it hurts

checking each wait type explain

3.

index fragmentation

SELECT
    *
   ,wait_time_ms/waiting_tasks_count AS 'Avg Wait in ms'
FROM
   sys.dm_os_wait_stats 
WHERE
   waiting_tasks_count > 0
ORDER BY
   wait_time_ms DESC

SELECT OBJECT_NAME(ind.OBJECT_ID) AS TableName,
ind.name AS IndexName, indexstats.index_type_desc AS IndexType,
indexstats.avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats(DB_ID(), NULL, NULL, NULL, NULL) indexstats
INNER JOIN sys.indexes ind
ON ind.object_id = indexstats.object_id
AND ind.index_id = indexstats.index_id
WHERE indexstats.avg_fragmentation_in_percent > 35
ORDER BY indexstats.avg_fragmentation_in_percent DESC

4. MS

High waits on CLR_MANUAL_EVENT and CLR_AUTO_EVENT

Only job owner or sysadmin role can modify the job

the metadata could not be determined because statement uses a temp table

Two solutions proposed in this post

SSIS not working with temp tables

SELECT name
FROM   sys.procedures
WHERE  Object_definition(object_id) LIKE '%table_name%'

Imports System.IO
Imports System.Data
Imports System.Text.RegularExpressions
Module CreateRDL

Sub Main()

Dim filepath As String = “c:\temp”
Dim ds As DataSet = DbTools.GetRDLs()
Try
System.Console.WriteLine(“total rdl for this ID: ” & ds.Tables(0).Rows.Count)
System.Threading.Thread.Sleep(1500)

For Each dr As DataRow In ds.Tables(0).Rows

Dim filename As String = dr.Item(“Name”).ToString() & “.rdl”
Dim folder As String = dr.Item(“path”).ToString().Replace(“/”, “\”)
Dim lastpos As Integer = folder.LastIndexOf(“\”)
folder = folder.Substring(0, lastpos)

Dim xml As String = dr.Item(“content”).ToString().Replace(“”, “”)
”xml = xml.Replace(“XYZDB”, “XYZDB_NEW”)

Dim newxml As String = xml

”newxml = xml.Replace(“XYZDB”, “XYZDB_NEW”)

SaveTextToFile(filepath & folder, filename, newxml)
System.Console.WriteLine(DateTime.Now & ” saving file ” & filepath & folder & “\” & filename)
System.Threading.Thread.Sleep(100)

Next

Catch ex As Exception
System.Console.WriteLine(ex.Message)
End Try
End Sub

Public Sub CreatePath(ByVal path As String)
Try
If Not Directory.Exists(path) Then
Directory.CreateDirectory(path)

End If

Catch ex As Exception
System.Console.WriteLine(ex.Message)
End Try
End Sub

Public Sub dummy()

‘xml = xml.Replace(“<DataSourceReference>XYZDB</DataSourceReference>”, “<DataSourceReference>netforumIAQA</DataSourceReference>”)
‘xml = xml.Replace(“<DataSource Name=””XYZDB””>”, “<DataSource Name=””XYZDB_NEW””>”)
‘xml = xml.Replace(“<DataSourceName>XYZDB</DataSourceName>”, “<DataSourceName>XYZDB_NEW</DataSourceName>”)

End Sub
Public Sub SaveTextToFile(ByVal FullPath As String, ByVal filename As String, ByVal strData As String, Optional ByVal ErrInfo As String = “”)

Dim bAns As Boolean = False
Dim objReader As StreamWriter
