Application is not accessible through Tomcat.
we are using CA SDM 17.2 which is upgraded and migrated from 14.1 on windows server 2016. As our application not able to run since 21/12/2019 Saturday. When we check the services then all service CA SDM were running. After that we check the tomcat status using pdm_tomcat_nxd -c status then it shows "Unknown status (0) received for SERVICEDESK Tomcat " we restarted the server and again start all the services but issue is still same. Please assist ASAP.
