- .. container:: paragraph - - Once APEX is installed, a few configurations need to be done: - - .. container:: ulist - - - Create an APEX user and an APEX group (optional, if not - installed using RPM and DPKG) - - - Create environment settings for ``APEX_HOME`` and - ``APEX_USER``, required by the start scripts - - - Change settings of the logging framework (optional) - - - Create directories for logging, required (execution might - fail if directories do not exist or cannot be created) - -APEX User and Group -------------------- - - .. container:: paragraph - - On smaller installations and test systems, APEX can run as - any user or group. - - .. container:: paragraph - - However, if APEX is installed in production, we strongly - recommend you set up a dedicated user for running APEX. This - will isolate the execution of APEX to that user.
