125 .. container:: paragraph
126
127 A simple verification of an APEX installation can be done by
128 simply starting the APEXOnapPf without any configuration. On
129 Unix (or Cygwin) start the engine using
130 ``$APEX_HOME/bin/apexOnapPf.sh``. On Windows start the engine
131 using ``%APEX_HOME%\bin\apexOnapPf.bat``. The engine will fail
132 to fully start. However, if the output looks similar to the
133 following line, the APEX installation is realized.

156
157 OnapPfConfig.json is the file which contains the initial configuration to startup the ApexStarter service. The dmaap topics to be used for sending or receiving messages is also specified in the this file. Provide this file as argument while running the ApexOnapPf.

308 The ApexOnapPf is initialized using a configuration file:
309
310 .. container:: ulist
311
312 - OnapPfConfig.json

319 The configuration file is a JSON file containing the initial values for configuring the rest server for healthcheck and the pdp itself.
320 The topic infrastructure and the topics to be used for sending or receiving messages is specified in this configuration file.
