2 Known Problems and Workarounds GUI Limitations • Using the same HP Caliper GUI project for both HP-UX and Linux sometimes results in corruption of the project. When this occurs, the GUI will post an error message at the end of a collection run saying it failed to save the information to the project. This limitation can be avoided by using separate workspaces for HP-UX and Linux.
in the other. To enable marking of branch targets, set disasm_mark_branch_targets = True in the .caliperinit file or a configuration file. • Running HP Caliper on set-user-ID and set-group-ID programs For security reasons, the HP-UX kernel does not allow users to run HP Caliper or any other program to monitor a program that has its setuid or setgid bit set. If you run a set-user-ID program under HP Caliper, the setuid/setgid will not be honored.
• Missing function name for STUB. Shared bound executables make use of “stubs” to bridge calls between load modules. HP Caliper reports stubs with the name of the function they bridge to, for example: {STUB}->function in most, but not all cases. • A program that calls setjmp, forks, or execs a process with the child process doing a longjmp to the parent-saved address fails with the precise measurement configurations. To measure a program such as this, you must specify the --process-all option.
3 Installation Information Operating System Requirements HP-UX 11i v2 or later is required. Hardware Requirements HP Caliper is supported on the HP Integrity server family. Software Requirements Java Java version 1.5.0.03 is required if you want to attach HP Caliper to an application and enable attribution of samples to JVM compiled methods at run time. Java 1.5 is needed to run the HP Caliper GUI. Java 1.5 is also needed if you want to measure a Java application on HP-UX with HP Caliper.
The latest version of HP Caliper is available on the HP Caliper Web page at: http://hp.

6 Changes in Previous Releases This section describes changes for the three releases prior to this one. Changes in Release 5.3 New Options and Enhancements The HP Caliper 5.3 release has the following improvements: • A new option --sw-process-list, is added. This option is used in the system-wide mode (-w option) to specify a list processes to analyze. This option is used to reduce the overhead of Caliper in the system-wide mode.
Deletions None. Changes in Release 5.1 New Options and Enhancements to Options The HP Caliper 5.1 release has the following improvements: • The cstack report has been enhanced to report inter-process blocking primitives (semaphores, message queues, sockets, pipes, regular file descriptors, etc.). This process level blocking primitive information is provided in addition to the previously reported primitives (mutexes, rwlocks, condition variables, etc.).
• HP Caliper can now generate reports from Caliper databases created on a different OS than the one from which HP Caliper is reporting. You can now view measurement information on a different system than that used to make the measurement. • The –db-save option has a new argument, all, that specifies that symbols, code, and line tables should be saved to the HP Caliper database. This information can then be used to report without access to the original binaries.
Changes in Release 4.4 New Options and Enhancements to Options • The new option: --db-save=[syms][:code][:src] allows you to save in the database containing your measurements, additional information helpful in later reporting. This option must be used when the measurement is first made. You can then generate reports or view reports in the GUI without needing access to the system where data was collected.
