Installation and Upgrade Guide

7.8.10 Initializing and Running the Performance Data Collector Base Software
(Optional)
The Performance Data Collector for HP OpenVMS (TDC) collects and manages configuration
and performance data for analysis by other applications. TDC_RT Version 2.2 is a run-time only
(base) variant of the TDC software that is installed automatically with the OpenVMS operating
system for use on specific operating system platforms.
Use of the TDC_RT software is not required. If you do not plan to use TDC_RT or any products
that depend on it, you can skip to the next section.
TDC_RT does not run automatically when the system starts, but any suitably privileged user
can start the software manually. This section includes information about system parameters,
privileges and quotas, startup, and installation in OpenVMS Clusters.
NOTE: Do not attempt to explicitly remove TDC_RT from your system. The PRODUCT REMOVE
command is not supported for TDC_RT although there appears to be an option to remove it.
TDC_RT is installed with the operating system and is tightly bound with it. HP or third-party
applications might require TDC_RT. Attempts to remove it might not work as expected and can
create undesirable side effects. An attempt to remove it results in a message similar to the
following:
%PCSI-E-HRDREF, product HP TDC_RT V2.3 is referenced by HP I64VMS OPENVMS
V8.3-1H1
The two products listed above are tightly bound by a software dependency.
If you override the recommendation to terminate the operation, the
referenced product will be removed, but the referencing product will have
an unsatisfied software dependency and may no longer function correctly.
Please review the referencing product’s documentation on requirements.
Answer YES to the following question to terminate the PRODUCT command.
However, if you are sure you want to remove the referenced product then
answer NO to continue the operation.
Terminating is strongly recommended. Do you want to terminate? [YES]
7.8.10.1 User Privileges and Quotas
Users of TDC_RT require various privileges, depending on the types of data to be collected.
Online help is available when running the collector application and specifies the privileges
required to collect each type of data. Enabling the following set of privileges enables collection
of all data items: CMKRNL, LOG_IO, NETMBX, PHY_IO, SYSLCK, SYSPRV, WORLD.
Users of the product also require working set quotas (WSQUO) greater than 7000 pagelets.
7.8.10.2 Startup File
TDC_RT provides a startup file that should be launched during system startup. The startup file
defines several logical names required for use of the product, but the startup file does not actually
start the data collector.
Add the following line to SYS$MANAGER:SYSTARTUP_VMS.COM:
$ @SYS$STARTUP:TDC$STARTUP
To directly run TDC$STARTUP.COM, SYSNAM privilege is required.
