RE: ADMIN PLZ REPLY - FW: !!Please Read - Oracle-L moving!!
Bruce, Thanks for all your work, support, and honesty. It's appreciated. Henry -Original Message- Bruce A. Bergman Sent: Thursday, January 22, 2004 11:14 AM To: Multiple recipients of list ORACLE-L Yes, this is legitimate. Jared and I have been talking recently about this. This list has just outgrown what Fat City can handle. While I'd like to think that I've always provided adequate-to-good service for the list, it's never been "great", and with the list growing, and traffic growing, my concern is that I just won't be able to continue to give the list good service. It makes me sick to think that, because I really have enjoyed giving back to the Oracle-L community, and because y'all have supported ME so well in the past, but I just don't want to see anything deteriorate simply because the volume exceeds what we can handle here. The list archives here will be available as long as Fat City continues to be in existence, so those of you who are searching for old topics are quite welcome to use the facilities here. It won't be going away. Jared has always been an awesome list owner, and I know he'll continue to make sure the list is successful. This move is just an indication of the relevancy and successful growth of the Oracle-L list, and I know it will continue. I wish you all the best in your new home, and I'll see you over there in a minute. :-) thanks, bruce bergman ListMaster, Fat City Hosting -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Bruce A.

RE: List problems (duplicate?)
For the record, I've been having the same problem at two email addresses. Iguess one question is whether it is consistently the same email that no onegets. If it's my mail gateway seeing it as spam, will everyone see it as spam?For example I got Dan's "Partioning question (duplicate?)" email from lateyesterday afternoon, but I never got the original post (even though I see it onthe fatcity.com website). Obviously Dan never got the original post either. Didanyone? This might help to narrow down the source of the problem.

I'm not seeing a lot of volume nor> anything I've sent recently. Funny you should ask.If you go to fatcity.com you will see that all email is arriving there unmolested. Several emails I sent did not appear in my inbox at 2 different addresses, yet they are on the server at fatcity.com. The most likely problem is that something is happening to them after they leave fatcity. The question is what. fatcity is on an ISP (RoadRunner ) that happens to allow dynamic IP addresses, a favorite tactic of spammers. RoadRunner therefore frequently is seen on blacklists, though fatcity is not responsible for any of the spam.That's one possibility. There are others. * your mail gateway is intercepting it as spam * your company's spam filter is deleting it. * ... ? Fatcity ( aka Bruce Bergman ) provides this service to oracle-l free. As such, there's a limit to how much time he can spend on this. Bruce has become an IS director and finds that his time is rather limited. Imagine that? ;) The number of subscribers experiencing this problem, or at least reporting it, is very small. Options are to ride it out, or find a new venue for this list.

RE: stress testing
Good catch on the array. I never noticed that. Henry -Original Message- Jared Still Sent: Monday, January 05, 2004 10:59 AM To: Multiple recipients of list ORACLE-L The patch I refer to is one I made that didn't make it into the most recent version of yapppack. YP uses an array as internal storage, and walks through it with a for i in 1..n loop. Since arrays are sparsely populated there is a fair chance of hitting an array element that does not exist. The patch consists of rewriting the loop with array.first/next/last in a while loop to avoid the problem. Yes, it is high level, but it can pinpoint time periods that you may want to investigate.

The conditions that need to be met depend on the dynamic_sampling initialization parameter in effect for the session. The default is 1 which practically disables dynamic sampling. 0 will totally disable it but IMHO the conditions for dynamic_sampling=1 are so rare (in practice) that one can regard it as off.

RE: Should we stop analyzing?
Makes sense, BUT... "If the data changes A LOT you should of course re-analyze." is assuming you know when that happens. You are assuming communication between users, developers, and DBAs. Communication is my New Year's Resolution. I would at least suggest exporting stats before changing them. Then there are all the extra problems such as retaining histograms with 8i, applications which constantly insert/delete from temporary tables (not Oracle temp tables), ... Henry -Original Message- >>But then I listened to Dave Ensor at the UKOUG conference, and he said roughly this: * Stop analyzing after the first analyze. It's the new stats that cause the optimizer to change execution plans. * "I know that big tables tend to stay big. Small tables stay small. Unique indexes stay unique and non-unique indexes stay non-unique..." * If the data changes A LOT you should of course re-analyze.

RE: select via dblink does not use index
Yechial, It's been a couple of years since I worked on tuning queries with db links, but a couple of issues come to mind:is the correct table being used for the inner table of the join, is too much data being sent over the network. -is the correct table being used for the inner table: I remember in earlier versions of Oracle, the local table was always the driving table. I don't know if that is stll the case, but it would be clear from the explain plan. The smaller table (local_table) should be the inner table of your hash join. Of course if this is the case, the full 1M records of the remote_table are being pulled across and compared to the hash table. ( a 10046 trace should help show if this is where the time is going) -is too much data being sent over the network: Assuming your result set is much smaller than the number of records in your remote table, you can run the query on the remote side and then bring back the result set. On the Target database create a view (create view my_remote_view as select * from target_table, [EMAIL PROTECTED] where ...). Kick off the query from your source database using (select * from [EMAIL PROTECTED]). The query is run on the remote side with only the result set passed back. Of course you now have to check if the correct table is being used as the inner table for the hash join (see the first point). If not, a different execution plan might be necessary. There also might be some newer features provided for distributed queries which I haven't had the chance to use yet. Henry -Original Message- Adar Sent: Thursday, December 04, 2003 8:29 AM To: Multiple recipients of list ORACLE-L Here are all the details: Source database 9.2.0.4 (upgrade from 8.1.6.3.4).

RE: View definition oddities
Jared,
Thanks, but what I was wondering is how the views got created in the
first place. If the field name needs an alias (i.e. substr(x,i,j)) and you
include this alias in the CREATE VIEW ddl, it will also appear in
dba_views.text. If you don't include the alias in the DDL, the view won't be
created. Yet we have views with no aliases in dba_views.text, yet these aliased
(column names) are in column_name.dba_tab_columns. Also, if I just run the
script from dba_views.text I get the error saying I need the alias. How did
these views get into the database?
Henry

you could probably tear apart a trace file and learn how oracle is reassembling the view from the DD.
A hard parse on a view can produce
250k of trace file. It is easier
to recreate by generating the ddl from a combination of all_tab_columns and all_views. Been there, done that. :)Jared
