| J. Duke | 319a3b9 | 2007-12-01 00:00:00 +0000 | [diff] [blame^] | 1 | This directory contains tools and tests associated with creating the |
| 2 | class list for class data sharing. |
| 3 | |
| 4 | The class list is produced by running the refWorkload startup3 benchmark with |
| 5 | the -verbose:class option. The -Xshare:off option must also be used so that |
| 6 | bootclasspath classes are loaded from rt.jar. The MakeClasslist program |
| 7 | should be built into the jar file makeclasslist.jar and is run |
| 8 | on one of the logs from each of the benchmarks in the following fashion: |
| 9 | |
| 10 | cd .../results.startup3 |
| 11 | $JAVA_HOME/bin/java -jar makeclasslist.jar results.Noop/results_1/log results.Framer/results_1/log results.XFramer/results_1/log results.JEdit/results_1/log results.LimeWire/results_1/log results.NetBeans/results_1/log |
| 12 | |
| 13 | Presently, $JAVA_HOME must be the same path used to run the startup3 benchmark. |
| 14 | |
| 15 | The logs are deliberately concatenated in roughly smallest to largest |
| 16 | order based on application size. The resulting output is redirected |
| 17 | into a file and results in one of classlist.solaris, classlist.linux, |
| 18 | or classlist.windows. These files are checked in to the workspace. A |
| 19 | necessary checksum (AddJsum.java) is added to the final classlist |
| 20 | (installed in lib/ or jre/lib/) during the build process by the |
| 21 | makefiles in make/java/redist. |
| 22 | |
| 23 | In a forthcoming JDK build we plan to manually add the dependent |
| 24 | classes for the calendar manager Glow, which pulls in the Preferences |
| 25 | classes and, on Unix platforms, the XML parsing classes. |
| 26 | |
| 27 | The properties file supplied to the refworkload is approximately the |
| 28 | following: |
| 29 | |
| 30 | javahome=/usr/java/j2sdk1.5.0 |
| 31 | resultsdir=classlist-run |
| 32 | iterations=1 |
| 33 | benchmarks=startup3 |
| 34 | globalvmoptions=-client -Xshare:off -verbose:class |
