The Cluster Edition installer does not create RUN_server files.
However, if you create a RUN_server file,
you can add a new location for the error log.
If you do not provide a path to the error log, the Cluster Edition
adds an error log according to the:
Cluster input file errorlog location. This information is stored in the quorum device and used by the dataserver command.
Default location for error logs. If you do not supply an error log path, a log file named instance_name.log is created in the current working directory for dataserver.
You can change the log location stored on the quorum device using the qrmutil --errorlog parameter or with sybcluster ‘set instance errorlog’.
If you are starting the cluster instances using shell scripts, change the value of the dataserver -e parameter, which overrides other settings for the error log location.
