Within VPA, please follow the Help link; the Help contents list available user guides. | | |
|
Within VPA, select "Welcome" from the Help pulldown menu, then click on "What's new in VPA 6.2". Note that when you start VPA for the first time, the "Welcome" screen will automatically display. | | |
|
Dynamic help is also available. While VPA is open, simply press F1 in a view and a pane will open with information about the tool and the view you are in. | | |
|
VPA can open profiles generated on any server as long as they are in XML format. For remote profiling with AIX servers, you need a Power4 or Power5 processor on the system. | | |
|
No; you can generate a profile on the system and then copy VPA input files to your ThinkPad or desktop that is running VPA. | | |
|
No. Unfortunately, this is an RSE issue. In order to change the settings, you must right-click in order to delete the connection and create it again. | | |
|
When you open a listing file in VPA, it is associated with the current process and symbol that you have selected. Make sure you select the process and symbol that the listing file was generated with, and then associate the listing file. | | |
|
In Pipeline Analyzer, the Scroll mode and Resource mode views are defined in the .config file. You can not switch modes manually. If you open the .config file using a text editor, you will notice that the first line specifies the type of this file. But, once again, you cannot modify this type manually because, for Scroll mode and Resource mode files, the .pipe file contents are different. If you want to see the resource mode view working, you must find resource mode .pipe and .config files. For information about how to generate a .pipe file with resource information, please see the manuals in VPA Help. | | |

It happens when your free disk space is so limited so that the installer cannot extract itself successfully. Please ensure you have at least 200 MB free disk space. | | |
|
Please enter the following code:
#java -Xrunvpn_jpa:instructions=1 i2d.class &
#tprof -ujek -A -I -N -d -r report -x sleep 100 &
#trcon
#trcoff
|
Then Tprof can get the trace file between line 3 and line 4. If you think the time is too long, you can kill the process (sleep 100) manually. | | |
|
This limitation is due to the profiling tools not being found under the PATH environment variable. Please add its directory, such as C:\IBMPERF\bin, to the PATH environment variable. Then restart VPA so that the new PATH variable will take effect. | | |
|
VPA is using the Eclipse 3.1.1 SDK, and it appears to have a library conflict with Firefox 1.5.0.7. There are two views in Code Analyzer (Instruction Properties and Browser) that will not work on Fedora Core 6. VPA runs well on Fedora Core 5, and the Eclipse SDK it uses will be updated in future releases to solve this problem. | |
