How to fix Oracle OVN (Xsigo) startup errors

xms startup will fail with log4j errors

log4j:ERROR Error occured while converting date.
java.lang.NullPointerException

To fix the error stop xms

service xms stop

Changed log4j pattern in /opt/xsigo/xms/webapps/xms/WEB-INF/classes/log4j.xml
From

value="%d %-5p: %c - %m%n"

To

value="%d{yyyy-MM-dd HH:mm:ss}

Then start the xms, it should start with out any errors

service xms start
