Dropping user in Shared Exadata Infrastructure in Oracle Cloud is very slow
We have a local database in 11.2.0.4 and a database in the OCI Shared Exadata Infrastructure that we are moving to. The schemas in both environments have about the same number of objects, about 4000, consisting of the same usual tables, indexes, views, packages, LOBs, triggers, synonyms, etc.
DROP USER {user} CASCADE takes about 2 minutes in the local 11.2.0.4 database, but over 3 hours in the Cloud. I run a query to watch the progress to see if it is hung up one on object that is causing the time, but no, it just seems to drop only a handful of objects every few seconds.
