Loader controller

The loader controller (plc) manages data loaders by controlling the schedule in which the data loaders gather data from the system.

Default behavior

The loader controller service starts automatically when the primary host starts up.

Interactions

The loader controller service controls the data loaders, which collect data from the system and write it into the database. Sampling data loaders request cluster operation data from the data sources while other data loaders obtain it directly.

Using the plc service with SUSE Linux® Enterprise Server (SLES) 15

If you use IBM® Spectrum Symphony with SLES 15 and cannot start the plc service, try these solutions:
  • Edit the $EGO_TOP/perf/3.8/etc/plc.sh file and change -Xmx1024m to -Xmx2048m.
  • Edit the $EGO_TOP/eservice/esc/conf/services/plc_service.xml file and change the value of the MALLOC_ARENA_MAX parameter to 1.
