Team foundation power tools provide set of cmdlets to manage and deploy TFS content

Pre req

  1. Team Foundation – Team explorer
  2. Team Foundation – Power tools

 

I found some very use full must read basics links before we kick start

How to Fix : Script cannot be loaded because the execution of scripts is disabled on this system.

You can fix this issue in lot of different ways depending on your environment by running below command in powershell

1.

Set-ExecutionPolicy RemoteSigned

RemoteSigned  – all scripts you created yourself will be run, all scripts downloaded from the internet will need to be signed by a trusted publisher

2.

Set-ExecutionPolicy unrestricted

Unrestricted – Executes any script

3.

ExecutionPolicy ByPass -File “Script name”

Bypass a particular script

If you are in controlled or restricted environment

4.

Set-ExecutionPolicy -Scope “CurrentUser” -ExecutionPolicy “RemoteSigned”

or

Set-ExecutionPolicy -Scope “CurrentUser” -ExecutionPolicy “Unrestricted”

 
 

PowerShell – Execute Batch files & Executable file, Exes – Dynamically passing Parameters

In PowerShell you can execute a executable in 3 ways

  1. Using Invoke-Expression
  2. Call operator ‘&’  “invocation operator”
  3. System.Diagnostics.ProcessStartInfo

 

Original command c:\Progra~1\NetApp\snapdrive\sdcli.exe snap mount -r  -k -d X -s sqlsnap__sql_08-14-2014_10.15.41

1) Invoke-Expression

$snap= “snap mount -r  -k -d X -s sqlsnap__sql_08-14-2014_10.15.41″

Invoke-Expression -Command “c:\Progra~1\NetApp\snapdrive\sdcli.exe $snap”

2)Call operator

& “c:\Progra~1\NetApp\snapdrive\sdcli.exe ” $snap

3)

$psi = New-Object System.Diagnostics.ProcessStartInfo “c:\Progra~1\NetApp\snapdrive\sdcli.exe”
$psi.Arguments = $snap
[System.Diagnostics.Process]::Start($psi)

How to FIX: Manage Orphaned users in SQL SERVER with a simple script

Using below scripts

 

  • Fixes all orphaned users in the current database if a login exists
  • If a login does not exist in thesql server instance
    •  User will be removed  — @fix = 0
      • If a user is a schema owner then the schema is transferred to DBO and then user is removed from DB
    •  or A login will be created  — @fix = 1

 


DECLARE @t TABLE (

id INT IDENTITY(1, 1)

How to fix: Access to the remote server is denied because the current security context is not trusted SQL Server

You are seeing this error because you are trying to impersonate or  switching the execution context using EXECUTE AS clause and Executing a RPC on a linked server

 

LInked server

 

If you have a procedure on Server X

USE ServerXDB

Create procedure proc

execute as ‘TESTUSER’

Execute ServerY.TestDB.dbo.test

Select * from [ServerY] .TestDb.dbo.testtable

To Fix this you have two options
  1. Enable Trusty worthy on ServerXDB database on Serverx
  2. Remove the execute as clause in the procedure and grant execute privileges to user we used to set up the linked server

 

you can also try by signing a certificate on the proc procedure but I havent tried it

How to fix : Server is not configured for RPC.

.Net SqlClient Data Provider: Msg 7411, Level 16, State 1, Line 3

Server name is not configured for RPC.

 

If you receive an error something like this most likely is from the Linked server its because when you try to run a remote procedure call like stored procedures.. Linked server setup should have RPC enabled

In order to fix this change the Linked server properties

EXEC sp_serveroption ‘server_name’, ‘rpc’, ‘true’;

EXEC sp_serveroption ‘server_name’, ‘rpc out’, ‘true’;

or we can change usi SSMS GUI interface

 

Reomote procedure linked server
