Re: shared pool waits

In our case , optimizer_adaptive_plans TRUE and optimizer_adaptive_statistics as FALSE. But in any case, if this is doing high number of soft parses and that is causing issue, wont this resulted into high number of child cursor or version count. The max number of version count for this sql i saw is ~84 during this ~15 minutes period for ~190K execution of this select query. But yes there is no change in plan its keep using same plan for all the executions. Is this really pointing to an issue related to adaptive feature or parsing?
