Transcription

1 W706 Troubleshooting Transactions Using SQL Profiler Pre-requisites: Session W607 or similar knowledge A perfect follow-up to session W607, this class will provide a more detailed look at the specific ways you can utilize SQL Profiler to troubleshoot events in your Prophet 21 solution. You'll also learn how the results achieved in SQL Profiler can be used to assist in creating reports. You won't want to miss this exciting and informative session. Ron Schorr Quality Assurance Wednesday, 5:00 p.m. 2 Session Objectives SQL Profiler can be used to view all SQL statements being passed between the Prophet 21 application and the database SQL Query Analyzer can be used to interpret the statements from the profiler and convert them into data These tools are essential for understanding the inner workings of the Prophet 21 application

2 3 Session Objectives Reviewing the SQL in Profiler can help you determine the code to use for reports and data queries Help you understand which tables are used for different purposes 4 SQL Server Profiler Where do you find Profiler? SQL Server Profiler can be selected from the SQL Server 2005 menu Performance Tools Profiler can also be accessed via the tools menu in SQL Server Management Studio

3 5 SQL Profiler Connect to SQL server SQL authentication or Windows authentication System Admin rights are required 6 SQL Profiler Trace Properties Select template and/or trace name

4 7 SQL Profiler Trace Properties Select events to display TSQL Stored Procedures Starting or completed 8 SQL Profiler Trace Properties Select columns to display Text data Login name Database name Application DB reads Duration

5 9 SQL Profiler Trace Filters Filter out unwanted data Specify login Specify DB Any column 10 SQL Profiler Trace Template Allows you to set up most common elements and save for re-use

6 11 SQL Profiler Trace Results Shows the data activity in the system 12 SQL Profiler Trace Results Highlight row to show full statement below

7 13 Query Analyzer Run Query You can cut and paste from Profiler to run 14 Troubleshooting Example Order Missing Salesperson tells you that an order they recently created is no longer showing in the system They are getting a message when entering the order number Enter a valid ID or Leave ID Blank You will use SQL Profiler to trace the process of entering the order number in the Order Processing Screen to simulate the message reported by the user

8 15 Troubleshooting Example Order Missing Using Profiler, you find the statement that retrieves order information You ll want to review this in Query Analyzer 16 Troubleshooting Example Order Missing After running the statement in Query Analyzer, you find that as noted in the message, the order can not be found You ll want to focus on the JOINS section of SQL

9 17 Troubleshooting Example Order Missing By systematically commenting (--) lines of code, you can run the query until the order appears In this instance, it is the join to Users that is causing the order to not appear 18 Troubleshooting Example Order Missing The join to Users is on the value taker in oe_hdr Running another query will show the value is null Select Taker from oe_hdr(nolock) where order_no = 87515

10 19 Troubleshooting Example Missing Line In this scenario, an order shows two lines in a drill down but only is showing one line in Order Processing Follow the same steps from the previous example: Gather a trace Identify the SQL Move it to Query Analyzer and run Notice results similar to those seen in OE Systematically comment rows until results are returned Notice that UOM doesn t exist for that item 20 Troubleshooting Example IMI In this example you can see that Profiler and Query Analyzer can show you the inner workings of a screen Run Item Master Inquiry while running a trace You ll notice that the fields you see on the screen match the values that you are seeing in the query results By reviewing the SQL statements you can better understand where the data is coming from that makes up the values you are seeing

12 23 Troubleshooting Example IMI 24 Return on Investment Opportunity These tools and processes allow you to solve problems quickly and reduce downtime Powerful tool for understanding performance concerns Creates a portal to your data and increases understanding of the application Access to more information allows you to make more informed decisions

13 25 Suggested Action Plan Run Profiler wide open and look at the traffic Apply filters and events to make the data more meaningful to you Copy statements from traces and manipulate them to develop reports or queries for specific data needs Review the data in order to determine how the application is working and to better understand why things are occurring in the system 26 Additional Resources SQL Server Books Online ;EN-US;pwebcst (Microsoft WebCasts) Educational Services - MS SQL Server 2005 Coming in June Customer Web Site - Data Dictionary default.aspx Inside SQL volumes (various authors)

14 27 Summary SQL Profiler is the most powerful tool for understanding the inner workings of the Prophet 21 application Profiler and Query Analyzer may be used to determine the data returned to the application Using these tools can greatly enhance your ability to solve problems and reduce downtime Great tool for writing reports 28 Thank You for Attending W706 Troubleshooting Transactions Using SQL Profiler Ron Schorr Please submit the Session Feedback Form To receive NASBA credits, please be sure to complete the Session Feedback Form and sign the class roster in the back of the room
