server0 not starting; ERROR => Can't open property file
I have installed SAP EP 6.0 and it was working fine till yesterday.
But now when I am trying to open the Portal (http://hostname:50000/irj) it says Page cannot be displayed.
Also when I try to login to Visual Admin I get this error message:-
Unable to lookup connection Default http://sbdep:8101/msgserver/text/logon returned empty list of connection parameters
I restarted the EP instance (not rebooted) and the JC00 and SCS01 have started normally,but portal is till not UP.
Have found the following details in the logs:-
[Thr 47609482135840] *** ERROR => Can't open property file [/usr/sap/EPD/JC00/SDM/program/config/sdm_jstartup.properties] [jstartxx_mt. 1952]
[Thr 47609482135840] *** ERROR => JStartupReadArgumentsEx: can't enumerate nodes [/usr/sap/EPD/JC00/j2ee/cluster/instance.properties:/usr/sap/EPD/JC00/SDM/program/config/sdm_jstartup.properties] (rc = -1) [jstartxx_mt. 524]
Kindly suggest where cud be the issue and how do I proceed.
