Pipelined functions

Doh !!

I just figured it out .. "set arraysize 1" was the missing link ... one guy replied to my posting on forum://Metalink:oracle_plsql that it might be client side caching and that prompted me to experiment with arraysize.

So, it was an issue with sqlplus setting and not pipelining, which I am happy to report works just fine ... now lines for attempt 1 appear BEFORE attempt 2 (each attempt compiles invalid objects in the database), previously they used to appear at the same time. e.g.

13:18:20 SQL> set heading off pagesize 0 trimspool on line 200 arraysize 1
13:18:24 SQL> select * from table(system.dbf_compile_invalid());
--
-- Compile Attempt [1] Found 3 invalid objects.
-- Initial invalids "3", now "3". [time: 2.000 sec.]
--
-- Compile Attempt [2] Found 3 invalid objects.
-- Initial invalids "3", now "3". [time: 2.000 sec.]
--
-- # Of invalid objects is constant, so I'll stop now with "3" invalids.
--
-- Outputting a list of commands to recompile remaining invalid objects.
-- Listing Commands to be executed ...
--
-- select * from table(system.dbutil.show_errors(666615));
ALTER PACKAGE "SQLAB"."QUEST_SL_ERRORS_PKG" COMPILE BODY REUSE SETTINGS -- 666615;
--
-- select * from table(system.dbutil.show_errors(666649));
ALTER PACKAGE "SQLAB"."QUEST_SL_SCHEDULED_COLLECTOR" COMPILE BODY REUSE SETTINGS -- 666649;
--
-- select * from table(system.dbutil.show_errors(666662));
ALTER PACKAGE "SQLAB"."QUEST_SL_USER_MANAGER" COMPILE BODY REUSE SETTINGS -- 666662;
-- End Of Listing ...

Subject: Pipelined functions

I have a question related to pipelined functions ...

I have a function which performs a task in a loop. I have piped messages at the beginning and end of the loop and expect them to appear as soon as they are piped. But there seems to be a difference of opinion between oracle's and my definition of "as soon as". I see these messages appear after 2/3 loops instead of each loop.

Does anyone know why this should happen? Any way to trace the piped messages? 10046 doesn't cut it for me. BTW this is 9202. I did search for Metalink for bugs but didn't find any obvious ones. Anyone know the internals (or heard any rumors) of pipelining ... like is there a buffer size, when reached messages are output? something like that?
