Re: Oracle 817 freezing

Dick,

    I have seen something similar, but with shared servers (obviously not your case - your reference to dedicated servers is presumably not by opposition to shared servers), but perhaps the reason for the freeze is related.
In my case, the shared pool was too small (although the large pool was adequate). Instead of returning ORA-I don't know how much as it should have, Oracle exhibited exactly the behavior you describe. I couldn't reproduce it in 9.2.
