I think that indexing the 'profile' table on entpc and laccess could be a good thing to start with.
Probably some work to do on MSG_HISTORY as well. You are right about bind variables, but it won't help the queries on MSG_HISTORY, where the long string of ORs is obviously dynamically built. Oracle doesn't often choose to iterate as it should with a long string of ORs (or a long IN list), the 'FIRST_ROWS' hint may help. You can also tell your developers to review the English irregular verbs, especially 'to send'. Forget about the magical INIT parameter.
