Performance Check Event Set Requirements

In order for SequentLINK V4.3.0 to collect performance data, the following requirements must be satisfied:
NOTE:
ptx/PDC may not have been installed by Sequent Manufacturing. If your system is running DYNIX/ptx V4.4.2 or later and you want SequentLINK to run Performance Check, ensure that ptx/PDC is installed.
NOTE:
ptx/PDC V1.1 is included in the release of DYNIX/ptx V4.4.4. ptx/PDC V1.0 (which is not sufficient to run Performance Check) was released with DYNIX/ptx V4.4.2. To collect performance data on systems with DYNIX/ptx V4.4.2 and SequentLINK V4.3.0, Version 1.1 of ptx/PDC must be installed.

OS Availability Event Requirements

The OS Availability Event uses information from the /var/adm/wtmp file. Therefore, in order for this event to function properly, this file must exist and must be in this location. (There is a symbolic link to this file from /etc/wtmp .)
Beginning with DYNIX/ptx V4.5.0, a new file holding only wtmp accounting records was created. SequentLINK V4.3.0 will use this file when available, eliminating the need for /var/adm/wtmp .
