Title: Meddelelse
Rajesh,
SYSDATE is of datatype DATE (that's what the documentation says), i.e. it
contains century, year, month, day, hour, minute and second (without
decimals).
I have made a little test. FirstIdump a
SYSDATE to see the internal representation. Then Icreate a table with
Tanel,
Oracle 9-2 SQL Ref manual. Lob storage clause.
The options for lobs on creation are:
CACHE
NO CACHE
CACHE READS
I don't think the last one appeared until 9.2
I was wrong about caching only writes, though -
one of the joys of trying to quote everything from
memory.
The CACHE
It's just one example of my general suggestion that messing about
with block sizes rarely has any direct performance benefit. But
if you can put something out of the way where it can't do so much
damage then the performance of everything else might benefit.
Regards
Jonathan Lewis

Thank you for this note, I had somehow missed this important improvement.

i apologize if someone posted this answer(i missed it if you did), but why do cached
lobs require writes on the control file? and jonathan said that isnt 'necessarily'
bad. is that because there isnt alot of I/O?
so caching lobs are primarily useful for read only or read 'mostly' LOBs?

That's really interesting, that switch between 7 and 8

Hallo,
I would like to write the code to atrigger that makes insert into another table inly

PREFERED_NUMBER = 1 and TELEPHONE_TYPE_ID in (1,2, 5)

They seem to vary according to whether I queue the job from a windows client

Hi,
From Note: 69028.1 on Metalink
The datatype returned is 13 and not 12, the external DATE datatype.
This occurs because we rely on the TO_DATE function!
External datatype 13 is an internal c-structure whose length varies
depending on how the c-compiler represents the structure.
Note that

Changes the service to AutoStart when the machine reboots. As Thomas said,
the NT service has to be running for you to be able to start the database.
The service will stay running even if you shut the database down. Think of
the service as a backgrouond placeholder for the database.

information about oracle-l as well, it's the first hit in google when you

We move an application that uses
OPTIMIZER_MODE=RULE from Oracle8 to 9i. Most of it is fine, but there are two
queries that have a very different execution plan. In one case, the execution
time increases from less than a minute to more than an hour. Neither query uses
any of the new Oracle

Keith,
To my
knowledge, RBO has not changed. That includes NOT dealing w/ IOT.
So, I think if you execute a query that references an IOT, you'll implicitly
invoke the CBO. That would explain why the plan is changing. So, did
you change a table from heap to IOT when you moved

There is not enough memory to start a dedicated connection. sochange the server mode from dedicated to shared, (you can do it change some parameters in init_sid.ora file see oracle documentation).
If you are going to change the server mode to shared and you have two databaseon the same machine,

Tom,
As stated earlier, here the intention is to startup the database using OEM
only and without using windows service. As for as I understand if the
OracleServiceSID is properly setup and if startmode for the service is set
to automatic then it will startup the database automatically once you
That's true.
Dharminder
There is a pretty good explanation in this usenet thread:
Well, you can't. Windows is different from other systems in that you have
these services that have to be running in the background. Once the
services are running, you can use OEM to shutdown and startup the database.
But the service has to be running first.
Sorry.
Have you looked at OEM Jobs?
Dharminder,
OracleServiceSID starts the database automatically, because by default
the registry key ORA_SID_AUTOSTART IN
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0 is set to TRUE.
If you don't want your OracleServiceSID to start the database
automatically, change the value to FALSE.

Mladen,
Thanks for info. So all the dirty blocks need to be written to disk after eachcheckpoint. After that is donethe status becomes 'INACTIVE'. Just that sometimes this is very unpredictable.
My question : Ifa log switch always causes a implicit checkpoint then what is the need for this
