Solution:

This exception is observed mainly in DB2 database and is caused due to insufficient DB buffer page size. Please increase the buffer page size to 32K to resolve it.

I am getting NullPointerException while creating a domain on DB2 database java.lang.NullPointerException at com.tibco.pof.authorization.AuthorizationDomain.install_5_1_3(AuthorizationDomain.java:225)
