PMDF System Manager's Guide
Chapter 8
Maintaining the Configuration
The critical PMDF configuration files,
- the configuration file, discussed in Section 1.2, Section 2.2
and Section 2.3,
- the alias file, discussed in Chapter 3,
- the mappings file, discussed in Chapter 5,
- the conversion file, discussed in Chapter 6,
- the option file, discussed in Chapter 7,
- the security configuration file, discussed in Chapter 14,
- the system wide filter file, discussed in Section 16.2.3, and
- the circuit check configuration file, discussed in Section 31.3.1.1,
may be pre-processed and compiled into a single image referred to as a
compiled configuration. By pre-processing these files and storing them
into an image, the initialization time for PMDF is significantly
reduced thereby improving PMDF's performance. Compiling the
configuration will be discussed in Section 8.1.
When updating the PMDF configuration, regardless of whether the PMDF
configuration is compiled, it is important to ensure that any affected
components of PMDF are made aware of the change. That is, if the PMDF
configuration is not compiled, then components need to be restarted
after changes to the PMDF configuration files; if a compiled
configuration is used, then the configuration needs to be recompiled
after changes and then components need to be restarted. An
overview of what components need to be restarted when various changes
are made to the PMDF configuration is provided in Section 8.2.
