javax.naming.NameNotFoundException: Unable to resolve 'jdbc.oamds'. Resolved 'jdbc'; remaining name 'oamds'
  at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(BasicNamingNode.java:1139)

Solution:
this error is no harm because jdbc.oamds is for future version.

if you still want to remove this error

go to
base_domain/config/fmwconfig/mbeans (base_domain is you domain name)

and modify following files

idaas_mbeans.xml,
 rp_mbeans.xml, 
oauth_mbeans.xml,

change property oracle.security.idaas.common.config.mbeans.persistence.database.enabled to false
