How Installing the ppe.perf and ppe.pvt Filesets Alter Your System

PE Benchmarker consists of the Performance Collection Tool ppe.perf fileset and the Profile Visualization Tool ppe.pvt fileset. In addition, if ppe.perf is installed, ppe.dpcl must also be installed. Installing PE Benchmarker creates the directories and files detailed in the following table:

Table 6. ppe.perf and ppe.pvt directories and files installed

Directory or File	Description
/usr/lpp/ppe.perf/READMES	Directory containing necessary files to be read by the customer
/usr/lpp/ppe.perf/bin	Directory containing executables
/usr/lpp/ppe.perf/config	Directory containing configuration files PCT uses to determine hardware counter groups
/usr/lpp/ppe.perf/deinstl	Directory containing packaging information for uninstalling the product
/usr/lpp/ppe.perf/help	Directory containing help images and files
/usr/lpp/ppe.perf/lib	Directory containing libraries used by PCT
/usr/lpp/ppe.perf/resources	Directory containing JAVA resource bundles used for labelled text in graphical user interface
/usr/lpp/ppe.perf/samples	Directory containing sample programs and scripts
/usr/lpp/ppe.perf	Directory containing the necessary Performance Collection Tool files.
/usr/lpp/ppe.pvt	Directory containing the necessary Profile Visualization Tool files.

In addition, symbolic links set up for PE Benchmarker files and libraries are placed in the following directories.

/usr/include
/usr/lib
/etc

Installing DPCL files (ppe.dpcl)

If you install the ppe.perf fileset, you must also install the ppe.dpcl fileset. You need superuser (root) authority to install DPCL. If you plan to use tools built using DPCL with more than one node, you must install DPCL on all of the nodes you want to use. You can do this by making the same image available to the other nodes, either by copying or mounting the image file, then using installp to install the image. You can also set up a host list file and run installp via dsh (for SP systems only) or rsh, and install the DPCL filesets on multiple nodes simultaneously.

DPCL Installation Effects

Also, as part of the post-installation steps, the following steps occur.

The file /etc/services is modified in the following manner:
- If no entry for the dpclSD service is found, an entry is added using port 7895/tcp.
- If an entry exists for the dpclSD service that uses port 7895/tcp, no change is made to the /etc/services file.
The file /etc/inetd.conf is modified.
If no entry for the dpclSD service is found, an entry is added.
If an entry exists for the dpclSD service, no change is made to the /etc/inetd.conf file.
inetd is refreshed.
