Note:
* (step1, step 2) Both the Profiler trace and the Performance Monitor logs should be started and stopped at about the same time.
* (step 3, step 4) Once you have completed capturing the data for both tools, you are ready to perform the correlation analysis.
* (step 5) How to Correlate SQL Server Profiler Data with Performance Monitor Data Correlating Performance Monitor and Profiler data is a straightforward process that simply involves importing both sets of data into Profiler. Start Profiler and load the trace file you want to correlate.
From the main menu of Profiler, select File | Import Performance Data,
* With SQL Server Profiler, we have the tools to identify the causes of such spikes. We can import Performance Monitor log data and compare it directly with Profiler activity. If we see a spike in CPU utilization, we can identify which statement or statements were running at the same time, and diagnose potential problems.

You are creating a stored procedure named usp1. Usp1 will create a table that will be used during the execution of usp1. Only usp1 will be allowed to access the table.
You need to write the code required to create the table for usp1. The solution must minimize the need to recompile the stored procedure.
Which code segment should you use to create the table?

Correct Answer: A
You have a database named Database1. Database1 has two stored procedures named Proc1 and Proc2 and a table named Table1. Table1 has millions of rows.
Proc1 updates data in Table1. Proc2 reads data from Table1.
You discover that when Proc1 is executed to update more than 4,000 rows, Proc2 is blocked. The block affects all rows, including those that are not being updated by Proc1.
You need to ensure that when Proc1 is executing, Proc2 can access the data in Table1 that Proc1 is not updating.
What should you change Proc1 to do?
