materialized view log

2003-07-11 Thread Li, Xiangli
Hi, All
I have a question on how to interpret materialized view log, which has a
field change_vector$$. I think this fields record all the changes on master
table,  I need to understand the updates on the master table so I can
develop my own API to copy the change to a flat file.

Any help would be appreciated.

ODBC issue???

2001-05-29 Thread Li, Xiangli
Title: ODBC issue???





Hi, DBAs
We are running a third party application on oracle8.1.6 with oracle odbc drive8.1.6.3. 
Everything works fine when application launched a single process, but it generated following error message when two processes running concurrently.

 --ora 1461, 0, "can bind a LONG value only for insert into a LONG column"


I guess when running in multi-process mode, the SQL strings submitted from application to oracle server exceed the limitation on ODBC driver ( 4000 characters?).

Is there any other issues I missed?

Li

Subject:    RE: Listener.logwriting to renamed file


On NT, if you don't want to lose any listener.log entries and you want to
keep using the same logfile name then you will need to use set log_file
twice.


Also, under NT (at least with 815 and 817) don't specify an extension for
the log file - it automatically gets ".log" appended.


For example (something like the following untested code):

lsnrctl set log_file temp1
ren listener.log listener_tmp.log
lsnrctl set log_file listener
copy /b listener_tmp.log + temp1.log  listener-date.log
del listener_tmp.log
del temp1.log

You could put the date into the archived listener log using the for command
to process output of date/t and time/t.
Note that using set log_file requires the listener password to be entered.
This can be automated under NT by using something like:

    rem create the temp file
   echo set password %lnrpwd% >  %lnrstart_file%
   echo stop %1 >> %lnrstart_file%
   echo exit   >> %lnrstart_file%
   echo.    >> %lnrstart_file%


    rem feed it into lsnrctl
   lsnrctl < %lnrstart_file%





Regards,
Bruce

Issue the SET LOG_FILE command using lsnrctl, then move/delete/whatever 
the old file.

The file handle listener is using is still pointed at the old file.  To 
fix this you need to stop and start the listener.  This will not affect 
anybody who is already connected.  I'm not sure if a reload will do the 
same thing.

The file handle listener is using is still pointed at the old file.  To fix this you need to stop and start the listener.  This will not affect anybody who is already connected.  I'm not sure if a reload will do the same thing.

Li,
 
1GB for Access would be huge...and cause very poor performance.  The only way to overcome the size limitation is to upgrade to a real database...preferably Oracle, but that SQL Server thing would work as well for a DB that size.

filesystem buffer ON/OFF ?

2001-04-18 Thread Li, Xiangli
Title: filesystem buffer ON/OFF ?





Hi, all
I have a database running oracle8.1.6 on HP-UX 11 (64 bit). We enable file system buffer on OS level.
I think bypassing the filesystem buffer will improve performance because right now, both oracle and the filesystem are performing this operation.

If I am right, should I turn off file system buffer only for data, index segments, how about system,rollback segs. and temporary 

segs. ?
Any suggestion are very welcomed, and any website talking about this? because I have to convince my SA guys.


thanks in advance.

Subject:    Qualifying columns to improve performance?


At a course some years ago, we were told that in join statements, we should qualify ALL our column names with the appropriate table name, not just those that may be ambiguous. The reason was that the parser would not need to spend time checking multiple tables to determine the table to which each column belongs.

 
Is this still a valid rule?
 
Does this apply to statements in PL/SQL procedures/packages?  Or are they different, because they are checked at compile time?

We have a application which causes oracle error 1461 when using oracle ODBC 8.1.6.3, but it works well with Microsoft ODBC driver, any suggestion for this?

And I also want to know where I can find all version oracle ODBC drivers because I may use 8.1.6.1.
