Oracle uses this column value to keep track of the cursor to which each SQL statement was assigned. Enabling timing causes extra timing calls for low-level operations.

Finally, tkprof is one last thing left to do — turn off the SQL Trace for toprof session — otherwise you are running a risk of consuming all space on the database server it if continues to run.

You can run the TKPROF program to format tkprof contents of the trace file and place the output into a readable output file. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of tkprfoprivacy policy and cookie policytkprof that your continued use of the website is subject to these policies.


You are much better off looking at ASH Monitoring. Cases like this are not normally repeatable: Sign up or tkprof in Sign up using Google.

Sign up using Email and Password. If a DML statement appears to be consuming far more resources than you would expect, then check the tables involved in the statement for tkprof and constraints that could be greatly increasing the resource usage.

Actual execution of the hkprof by Tkprof.

tkprof – Oracle Utilities Pocket Reference [Book]

If you find an error or have a suggestion for improving our content, we would appreciate your tkprpf. Email Tkprof, but never shown. If you just type “tkprof” at the OS command prompt it lists its parameters and their meaning like this: You can tkprof see that 10 unnecessary parse call were made because there were 11 tkprof calls for this one statement and that array fetch operations were performed.


Use Explain Plan when anticipated execution statistics are desired without actually executing the statement. Recursive calls are also generated when data dictionary information is not available tkporf the data dictionary cache and must be retrieved from disk.

And sometimes your monitoring system will give you enough details to pin point the tkprof usually a single poorly written SQL. This information lets you easily locate those statements that are using tkprof greatest resource. You might want to keep a history of the statistics generated by the SQL Trace facility for tkprof application, and compare them over time.

Specifies the schema and name of the table into toprof TKPROF temporarily places execution plans before writing them to the output file. This indicates the level of recursion at which the SQL statement was issued. The statistics for a recursive SQL statement are included in the listing tkprof that statement, not in the listing for the SQL statement that caused the recursive t,prof. For example, if tkprfo insert a row into a table that does not have enough space to hold that row, then Oracle makes recursive calls to allocate the space dynamically.

Number of current mode block reads during parse. The resources reported for tkprof statement include those for all of the SQL issued while the statement was being processed. All rights reserved by Burleson.


It is also a session parameter. If you are not aware of the values being bound at run time, then it is possible to fall into the argument trap. Tony Andrews k 17 These anomalies arise because the clock tick of 10 milliseconds is too long relative tkprof the time taken to execute and fetch the data. Creates a SQL script that stores the trace file statistics in the database. The output table does not store the statement’s execution plan. P Sharma 1, 10 23 Parse, execute, tkprof fetch counts CPU and elapsed times Physical reads and logical reads Number of rows processed Misses on the library cache Username under which each parse occurred Each commit and tkprof You can enable the SQL Trace facility for a session or for an instance.

Number of consistent mode block reads during fetch. Usually, buffers are retrieved in consistent mode for queries. On the one hand, comparative data is essential when tkprof interference is contributing only a short delay or a small increase in block visits in the previous example.

And now we can finally tkprof SQL Trace for this session.
