Database Upgrade - SPM
We are planning to upgrade our databases from 10.2.0.4 to 11.2.0.3. We are planning to use SQL plan management to retain the exisitng 10g plans and evalute and accept 11g plans at later stage if it looks better . We are planning to capture all the SQLs from appliction ( Say sql for one day) and load it to sql tunning set and import this tuning set to 11g SPM.My Question is, Is there any limiations on number of sqls that can be loaded to SPM.Do we have any performance issue if we load too many sqls from tuning set to SPM ?
