SolManDiag – SQL Trace (How to use it)
Typically, you should use the SQL Trace when you need to check the
behavior of a particular application. This is the following scenario:
� Launch the SQL Trace application
� Activate the SQL Trace.
� Run the application that you want to trace
� Deactivate the SQL Trace
� Set filters optionally
� Evaluate the trace
You can also evaluate an already existing trace.
The SQL Trace also provides functions for file administration.

SolManDiag - SQL Trace Filtering
The SQL Trace stores information about all database calls issued using Open or
Native SQL. When evaluating the trace using the SQL Trace Web application, however, you can enter filtering criteria to display only those entries, which are relevant for
your purposes.
SAP AG 2006, Diagnostics for Solution Manager - OM / 23
SolManDiag – OpenSQL Monitoring (SQL Trace – Features)
The SQL Trace function is an on-demand log of all SQL statements thatare issued against the database through Open and Native JDBC
methods. The SQL trace can be switched on or off dynamically from theweb application. The log format is database independent. Besides the SQL
statement text, each log record contains information about the point in time when the statement was executed, its duration, its input parameters and results (where applicable) as well as context information.
The SQL trace is especially useful for:
Development - SQL trace can help enterprise beans, servlet andJSP developers to learn which kind of database accesses their codeproduces.
Performance analysis - Typically, performance issues are caused by
inefficient database accesses. In this case SQL Trace can be used toshow the issued SQL statements and their duration, thus helping to
identify inefficient SQL statements.

SolManDiag Log Viewer
The Log Viewer can display structured and unstructured logs. Structured
logs are created by the SAP WebAS with header information and delimiters.
This allows the Log Viewer to recognize fields of the log records, and thus
allows filtering and searching of log records based on field content.

With the Web Dynpro Console administration tool, you can display the performance data for the times of a request to the J2EE Engine.
In contrast to Web Dynpro Framework, Client, and Applications, this function gives information about the response times of the individual steps of a request (starting within the J2EE Engine).
SAP AG 2006, Diagnostics for Solution Manager - OM / 57
SolManDiag – WebDynpro (Measuring Request Performance I)
Context:
The table lists the requests sorted by the length of time. The required response time, the number of methods involved, the method takingthe longest time, and the user are listed for each request.
Procedure:
Select a line
You get detailed information for the particular request.
Result
The performance data for a request includes the framework, application, and backend times.
The detailed information also includes the level of the methods, giving you information about the call depth of the methods called.
You can thus find out which query took the longest and which methods within a query consumed time. . .
