two ways I guess, 0) put the eniter schema in a read only table space 1.1) create another schema which will be the owner and for rest all give only select access, sys, system and the new schema owner passwords should be kept secret or 1.2) other than the present owner give everybody as select access, and sys, system and the orginal schema owner passwords should be kept secret thanks and take care..subodh ________________________________ From: Avadhani mys <avadhanimys@xxxxxxxxx> To: oracle-l <oracle-l@xxxxxxxxxxxxx> Sent: Monday, 22 June, 2009 17:27:34 Subject: How to convert schema to readonly schema.
