Solution:

I  added below parameter in parameter file and reboot the system.

Please check the following note: 
12C Database Instance Startup Fails With ORA-27102: OUT OF MEMORY Error On Solaris ( Doc ID 1987090.1 ) 

A workaround that has proven successful is to set the following parameter in the init/spfile and restart the database 



*._use_osm=FALSE
