Scanning Useless Users for all servers
1. Generate a script for all servers. The following script will be used to scan the version of useless users in all servers assigned to me. It may be a better to use the useless logins instead of useless users.
SELECT DISTINCT 'OSQL -U I270478 -P stupid1 -S ' + a.SQL_INSTNC_IP_ADDR +','+ CAST(b.SQL_INSTNC_PORT AS VARCHAR(5)) +' -d master -i "c:\UselessUsers.sql" -b -n -h-1'
FROM EDBA..vw_SERVR_DBA a, EDBA..vw_Server_inventory b
WHERE LAN_ID = 'I270478' AND a.MACHN_MGMT_IP_ADDR = b.MACHN_MGMT_IP_ADDR AND a.SQL_INSTNC_IP_ADDR = b.SQL_INSTNC_IP_ADDR
Save the generated script in the file, C:\UselessUsers.bat
2. Save the following script in the C:\UselessUsers.cmd file.
REM SET /P variable=[promptString] allows user to set the value of a variable to a line of input entered by the user.
REM Displays the specified promptString before reading the line of input.
@echo off & set /p osqluser=Type in your userid. Then hit Enter.
@echo off & set /p osqlpassword=Type in your password. Then hit Enter and minimumize your screen.
REM echo %date:~-4,4% returns year
REM echo %date:~-10,2% returns month
REM echo %date:~-7,2% returns day
UselessUsers.bat >> c:\UselessUsers-%date:~-4,4%%date:~-10,2%%date:~-7,2%-%random%.txt
@echo off & set osqluser=
@echo off & set osqlpassword=
3. Save the following script in the C:\UselessUsers.sql file
SET NOCOUNT ON
DECLARE
@dbname2 SYSNAME
DECLARE @sql2 VARCHAR(255)
CREATE TABLE #temptbl (Col1 VARCHAR(100), col2 VARBINARY(85))
DECLARE dbCur CURSOR FOR
SELECT name FROM sys.sysdatabases WHERE DATABASEPROPERTY(name, 'IsOffline') = 0
AND DATABASEPROPERTY(name, 'IsSuspect') = 0 AND DATABASEPROPERTY(name, 'IsReadOnly') = 0
OPEN dbCur
FETCH NEXT FROM dbCur INTO @dbname2
WHILE (@@FETCH_status = 0)
BEGIN
SET @sql2 = 'INSERT INTO #temptbl SELECT name, sid FROM '+@dbname2+'.sys.sysusers WHERE islogin <> 0 AND sid is NOT null AND name NOT in (''dbo'',''guest'')'
EXEC(@sql2)
FETCH NEXT FROM dbCur INTO @dbname2
END
CLOSE dbCur
DEALLOCATE dbCur
SELECT @@SERVERNAME, name uselessLogin FROM sys.syslogins WHERE NOT EXISTS (SELECT Col2 FROM #temptbl WHERE sid = Col2) AND sysadmin = 0 AND status <> 10 AND name NOT LIKE '%clusteradmin'
/* To disable all useless logins, we can include this snippet
SELECT 'ALTER LOGIN [' +name+ '] DISABLE' AlterLoginDisable FROM sys.syslogins WHERE NOT EXISTS (SELECT Col2 FROM #temptbl WHERE sid = Col2) AND sysadmin = 0 AND status <> 10 AND name NOT LIKE '%clusteradmin'
*/
DROP TABLE #temptbl
4. Run the C:\ OrphanUsers.cmd file. It will use the C:\UselessUsers.bat and the C:\UselessUsers.sql files, and output the results to the C:\UselessUsers ******* file.
