Re: [Pharo-project] load testing a database

by Tudor Girba

Hi, Sorry for the late reply, and thanks everyone for the suggestions. I did not provide much details because I am new to this domain and I wanted to see from the reactions if maybe I am not missing some relevant direction. We are trying to measure how an Oracle database can cope with an increase in usage (basically, there will be more users for the application). We are basing our analysis on typical SQL statements coming from the application. We are currently doing load testing by: - recording sql statements from some use cases that are considered to be important - generalizing them by replacing actual values with generic variables - providing meaningful values for the generic variables - replaying them against the database from several client machines - consuming the first record from the responses - reporting the timing of the statements - recording the CPU, memory and I/O load of the server However, I am interested in pitfalls, and in the way people interpret the results given that it is hard to determine what is a typical usage in terms of what statements to trigger and at what delays.

I see two possible ways. First recording the SQL statements and then replaying them (have fun with bind parameters). Second just running the application itself. > > Oh yeah, Oracle has a tool named RAT, no idea what the marketing department though there.

Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 775 by marcmoo...(a)gmail.com: Pane partially clipped http://code.google.com/p/moose-technology/issues/detail?id=775 Hello I have some small problem in Glamour. When I execute following in a Workspace | browser | browser := GLMTabulator new. browser row: #menuBar size: 25. "Bottom Part get hidden because of this" browser row: [ :r1 | r1 column: [ :c| c row: [:r | r column: #one; column: #two ] span: 2; row: #three. ]]. browser transmit to: #one; andShow: [:a | a title: 'One'. a list ]. browser transmit to: #two; andShow: [:a | a title: 'Two'. a list ]. browser transmit to: #three; andShow: [:a | a title: 'Three'. a list "title: 'List'" ]. browser openOn: (1 to: 10) the bottom part of the third pane is partially hidden. Do I something wrong? (A hacky workaround is to simplay add an additional row with size 25 -- which then is invisible) (See attached picture) Tested in Pharo 1.1 - 1.3 Marc Please fill in the labels with the following information: * Type-Defect * Component-Glamour Attachments: hidden.png 18.5 KB

realeasing moose 4.6

by Tudor Girba

Hi, As there is not much activity around Moose, there is hardly any point to wait for releasing 4.6. I will do it tomorrow. If you have objections, please raise them until then. Cheers, Doru -- www.tudorgirba.com "Reasonable is what we are accustomed with."

Issue 743 in moose-technology: This is strange that we have to systematically specify the class of the importer

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 743 by usman.bh...(a)gmail.com: This is strange that we have to systematically specify the class of the importer http://code.google.com/p/moose-technology/issues/detail?id=743 a typical sript to import a model is MooseSqueakClassPackageImporterTask new importerClass: SmalltalkImporter; model: model; addFromPackageNamed: #'Moose-TestResources-LAN'; run; yourself But it is rare that we should change the importerClass (it was useful when we had to import FAMIX2 and FAMIX3 side by side). I suggest that we introduce a default and that we initialize the importerClass to SmalltalkImporter.

Issue 738 in moose-technology: bugs in EyeSee

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Defect Priority-Medium Platform-Pharo Component-EyeSee New issue 738 by alexandr...(a)gmail.com: bugs in EyeSee http://code.google.com/p/moose-technology/issues/detail?id=738 I played with the matrix in EyeSee in a Pharo image. I found some problems: - #new:withAll: and #new: seems to raise an emergency debugger, whatever the value we provide - Many references are made that do not belong to EyeSee. For example #zero that refers to MalMatrixCoercion I also found other problems (e.g., hash). I added some tests for those. I produced version 0.9.2 Cheers, Alexandre
