Re: connect to the databases without using tnsnames.ora?
Thanks all for the answers. We do use Oracle Names here. Cc Harvest. --- [EMAIL PROTECTED] wrote: Neither sqlnet.ora or tnsnames.ora are required.

Re: Index questions
Thanks Don, Your explanation is very helpful.

Bitmapped indexes will be fast for the queryagainst
the 'Y's, but a
bitmapped index may not be appropriate if you are
getting lots of DML
activity on this.
Another option is to use NULL instead of the vast
majority value ('N' - in
this case) and create an index. The nulls won't be
indexed, so the index
will be small. This works best when there are
relatively few non-majority
values and they are the ones most
critically/commonly queried. A hint MAY
be required to make the CBO use the index. This
obviousy won't help on
queries against 'N' though. Example, ORDERS table
with a STATUS column -
98% 'Closed', 2% ('New' | 'Pending' |
'Whatever...'). Change the logical to
interprete NULL as 'Closed' and create an index on
ORDERS.STATUS. Queries
for open orders - ('Closed' | 'Pending' |
'Whatever...') become very fast.

not help with CBT(usually most of the values are

My question is : how about bitmap indexes? Should it
help a lot, or just a little bit?

Re: export the schema exclude two tables?
Claim,Jared,Peter,Rajesh: Thanks for the reply. I just try a different method. exp the two tables to a dump, truncate the tables, exp the rest to another dump. imp the two tables back to the database, ship the secpdn dump to the customer. The customer does not like that two tables, because there are two big and the data is useless. Thanks all. Chris --- [EMAIL PROTECTED] wrote: I tried a different way once - with the PL/SQL extensions to export package. It isn't described in the docs, but there is a file (dbmsexp.sql) in rdbms/admin directory. Basically for each table that needs special treatment, you insert a row in sys.expact$ and identify the PL/SQL code you want to call before or after the table is exported. I had PL/SQL functions that renamed the tables (rename emp to a_emp). It sort of worked; exp renamed the tables before copying the rows and then raised an ORA-942 error because the table wasn't found and then continued with the next table in the schema. One problem was that the exp dmp file still contained the create table statement for the excluded tables. The solution to that was to pre-create dummy tables on the target system with the same names... It was a while ago maybe in Oracle7.3. Right now I can't remember why I did it. Is there a limit on the number of tables you can list for the exp tables parameter? Maybe the issue was to speed up the exp or limit the size of the exp dump file? With a complete export, you can still create dummy tables on the target with the same names as the tables you want to exclude and run imp with ignore=n. This at least excludes certain tables from the imp (if not from the exp).

RE: How to set DBWR_WRITE_PROCESSES in Oracle8i?
Thanks Kirti and Paul for the reply. The instance is up for only 3 days. We know there are very heavy inserts in the database. Yes, There are high waits for 'buffer busy waits' event in V$SYSTEM_EVENT view. But I didn't see 'buffer busy waits' in V$SESSION_EVENT. I may try to increase the freelist to 12(I don't know whether it helps, anyway we have 12 Java threads insert data into the same table concurrently). Thanks, Chris --- Deshpande, Kirti [EMAIL PROTECTED] wrote: How long has the instance been up? It appears that the application is trying to read the same data blocks /or more sessions are trying to update the same data block or the free lists may need to be set properly to support concurrent INSERTs. So, before changing anything for DBWR process, I would suggest to check the top wait events from V$SYSTEM_EVENT view. You may see high waits for 'buffer busy wait' event. If so, I would trace it further using V$SESSION_EVENT and V$SESSION_WAIT (P1, P2 values) to find out the 'hot' segment and the file. You may have to review the pctfree, freelists, extent sizes etc. to address 'buffer busy waits'. For all you know, it could be just an application issue in scheduling the processes properly. And to answer your question about setting DBWR_WRITE_PROCESSES(actually the parameter is DB_WRITER_PROCESSES) you may want to check out Note# 97291.1 on Metalink. It has some good information.

Re: High DML Table - Suggestions??
I have a big table too, about 16GB. It is a vert static one(customer table), will add data once in it, but queried all the time, and do the segmentations against it all the time. It also has 12 indexes. Right now , the performance is ok. Any special consideration for such a big table. Thanks, Harvest. --- Christian Trassens [EMAIL PROTECTED] wrote: Don't put it in a buffer keep because of the amount of consistent gets the table could have. It seems to be a high volatile table.

Update Query
Seems like Oracle Doesn't have to the query like this: update tablea set firstname=tableb.firstname, lastname=tableb.lastname where tableb.id = tablea.id; I can have one, it works if it has a match for the two tables, otherwise the two columns updated to null: update tablea set (firstname,lastname) =(select firstname,lastname from tableb where tableb.id=tablea.id); Then the following one works, but very ugly: update tablea set (firstname,lastname) =(select firstname,lastname from tableb where tableb.id=tablea.id) where exists( select 'x' from tableb where tableb.id=tablea.id) Any suggestions?

wrong setting of sort_area_size
we had a customer of the sort_area_size=1000 in their database, the temp table space is 256MB, the db_block_size is 8k. They have some performance problem, I think it's probably related to the setting of sort_area_size(we have only one user). So what's the benefits/disadvantage of too big sort_area_size?

Re:Temporary Tablespace Design
Thanks Dick and Lisa for answering my question. I think I am going to either let the file auto-extend, or will try a smaller file as a start.

Which is faster??
I have the following scripts: insert into table select * from table2 ; So if use the about bulk statement in my application, and the table2 is big, say 10 million records, my concern is that it's going to fail because of the possible rollback segments failure. So then I have to use PL/SQL to create a cursor and commit every 5 records. What's the disadvantage of this?Will it be much slower than a bulk insert? Can I do it another way: create a stored procedure for this bulk insert, then pin this procedure in memory, does it still have RBS problem? Anyone has similar experience?

Drop a column in a 9 million records table
The database is Oracle8.1.7. I used the syntax: alter table foo drop column bar; Why it gives run out of RBS error? Is alter table a DDL? How does it use RBS? TIA Chris Harvest __ Do You Yahoo!?
