Here is a routine for a DOS batch file that checks tempdb. See the maintenance batch script for an example of validating command line arguments.
echo Verify tempdb size isql -U%1 -P%2 -S%3 -d%4 -i cktempdb.sql -o %5\cktempdb.out -n if NOT ERRORLEVEL 1 goto :tempdb_checked echo: echo An error occurred while checking the size of tempdb! goto :end :tempdb_checked find "tempdb is OK" %5\cktempdb.out if NOT ERRORLEVEL 1 goto :verified_tempdb echo: echo The tempdb database is less than 50M in size. goto :end :verified_tempdb echo hurray! :endHere is the isql script the batch file calls.
PRINT "Check the size of tempdb"
SELECT getdate()
