• Load Testing and Benchmarks on Oracle RAC, Romain, DB meeting, Dec 2007

01 Dec 2007

• Performance_RelationalAccess documentation

15 Nov 2007

• Create a tutorial

12 Nov 2007

• Adapt monitoring pages to the new LEMON website.

5 Nov 2007

• COOL performance : browseObjects (task #4381)

15 Oct 2007

• Stress tests with Balys on Oracle 11g
• COOL performance : SVMC Bulk Insert (task #5654)

11 Sep 2007

• Investigating differences between results of my tests and Gianni's : COOL220ExecutionPlanProblem

01 Aug 2007

• COOL 2.2.0 was released in July, we can test the differences between this release and the previous one
• UTBM Report

26 Jun 2007

• back to the Pvss2CoolTest with the help of Andrea

25 Jun 2007

• did some tests with flashback table scripts... need more feedback from Gianni & Andrea

20 Jun 2007

• develop Flashback Table scripts for Gianni : CoolTestFlashbackScripts

18 Jun 2007

• Calculate COOL data overhead (index...) : factor of 3.5 ... more details following : CoolDataOverhead

12 Jun 2007

• Use PVSS, PVSS2COOL in order to test them. Investigate documentation and Andrea's log.

11 Jun 2007

• Inserted different data sets for performance tests (Atlas DCS data => CoolInsertionTest). Space problem on CMSONR where the data is stored (not enough space to store all different data sets so the tests will be started with 7 days, 25d, 50d, 100d and 150d in a first time, we'll go with 1-year data after).

06 Jun 2007

• Found problems while running tests at night : RunningPerformanceTestsAtNight

04 Jun 2007

• NEW: if num clients == 0 then stop test and report ? => Define a condition for the client to stop in pyCoolClient, means define a new parameter ?

30 May 2007

• Develop & use a C++ client for COOL bulk storage (in order to fill 1 year data first then for performance testing)

22 May 2007

• FIX: merge stopClients et startTest (manager script)
• FIX: change the way to calculate the throughput in the reporter
• use mid-range servers : CoolInsertionTest
• kick out the threads => use fork()

08 May 2007

• BUG: Problem with pyCoolClient, increasing number of clients do not increase number IOV/s => python problem (threads cannot execute properly on multi cpu machine => back to processes)
• Persistency thread/proc test : same problem => python threads

07 May 2007

• NEW: use the variable isThreaded to chose threads or processes
• COOL 5000 prefetch test : no meaning full improvement

27 Apr 2007

• NEW: modify the report script to accept new changes (need more changes)

26 Apr 2007

• CHANGE: way to calculate average since test start, impact on client, startTest and report
• NEW: use cvs files instead of log files

25 Apr 2007

• INFO: BUG (not fixed) Segmentation fault with COOL_2_1_1 on slc4_ia32_gcc34 on exit.

24 Apr 2007

• INFO: pb w/ threads & COOL => there is a limitation on the throughput, perhaps due to system calls.

22 Apr 2007

• NEW: Documentation : Introduction
• NEW: Create a clean sql script that create ST_REPORT account and the views

20 Apr 2007

• FIX: Compute min, avg, max CPU utilization directly in the SQL statement
• FIX: Change the graphs presentation (more readable)

19 Apr 2007

• NEW: Add the number of clients to the metric graphs
• NEW: In report page add links at the top (to client & server nodes)
• FIX: Remove the buggy metric 0 (for time ellapsed since test start)

18 Apr 2007

• NEW: Add to the live reporter the wait events stats
• NEW: Add to the report script the new graphs (cpu, wait, metrics)
• FIX: Remove the avg CPU and total load on live reporter
• FIX: Change the code of pyCoolClient to new code by Andrea (4core test). Result: clients don't use the same connection anymore
