|j'ai trouvé l'outil d'analyse et d'optimisation de SQL400. Il est dans iseries navigator (demarrer / programmes / IBM iSeries Access for Windows / iSeries Navigator). Et la fenêtre "Run SQL Script" est au bout de mes connexions / (ma machine) / Bases de données / qtemp ; clic droit : execution de script||I found the tool for analysis and optimization of SQL400.

There are two ways to invoke the Visual Explain tool. The first, and most common, is through iSeries™ Navigator. The second is through the Visual Explain API, QQQVEXPL. You can start Visual Explain from any of the following windows in iSeries Navigator:
In addition, a database monitor table that was not created as a result of using iSeries Navigator can be explained through iSeries Navigator. First you must import the database monitor table into iSeries Navigator. To do this, right-click the SQL Performance Monitors and choose the Import option. Specify a name for the performance monitor (name it will be known by within iSeries Navigator) and the qualified name of the database monitor table. Be sure to select Detailed as the type of monitor. Detailed represents the file-based (STRDBMON) monitor while Summary represents the memory-resident monitor (which is not supported by Visual Explain). Once the monitor has been imported, follow the steps to start Visual Explain from within iSeries Navigator.
You can save your Visual Explain information as an SQL Performance monitor, which can be useful if you started the query from Run SQL Scripts and want to save the information for later comparison. Select Save as Performance monitor from the File menu.
